This was a follow-up from a City Council complaint as well as observation made by the Department of Public Works. It appears now that the Iowa Interstate Railroad will not perform any repairs until September of this year. bc3-4 City of Iowa City MEMORANDUM TO: Steve Atkins, City Manager. FROM: Larry Donner, Fire Chief �` DATE: June 7, 1989 RE: Proposal To Study Enhanced 9-1-1 And Emergency Communications Last year, the State of Iowa passed legislation requiring every county in the state to prepare a plan dealing with enhanced 9-1-1. Enhanced 9-1-1 automatically routes the call for help to the appropriate dispatch center and gives emergency dispatchers the caller's address. Currently, Iowa City, Johnson County, and the University of Iowa maintain 24 hour per day dispatch centers; Coralville contracts with the County for evening and weekend dispatching service. These dispatch centers serve as communication hubs for emergency medical services, fire departments, and law enforcement agencies within the County, The E9-1-1 legislation gives us an opportunity to assess our emergency communication needs and study the possibility of County -wide dispatching. As you recall, the City and County agreed to split the cost of hiring a consultant to do a formal evaluation of our current system and to evaluate the feasibility of combining dispatch centers in conjunction with E9-1-1 service. A committee was formed to solicit proposals and recommend a consultant to to the Iowa City Council and the Johnson County Board of Supervisors. Committee representatives from Iowa City, Johnson County, Coralville, and North Liberty reviewed six proposals and Interviewed three finalists, The E9-1-1 Ad -Hoc Committee on Communications Consultants recommends that Ronald Vegemast Engineering, Inc. be hired to do our study. Public safety communication system areas to be addressed in the study include: • Consideration of implementing a County -wide Enhanced 9-1-1 emergency telephone service. • Preliminary design of a multi -agency public safety communications center to the detail required to assess performance and to generate credible cost estimates. • Consideration of existing public safety radio systems to determine how they would interface with a central dispatch system. E9-1-1 page 2 There are two outstanding issues to be addressed, First, there is a question of whether or not a 28E agreement between the City and the County is required, and second, a local project manager will need to be named for the project. The committee feels these issues are minor and can be resolved administratively. At the conclusion of the study, Ronald Vegemast Engineering will provide a report of all data, findings, and recommendations based on Information and interviews conducted on-site with all agencies involved in emergency communications in Johnson County. The study should be completed within five months of the consultant receiving an executed copy of a contract. A firm fixed fee for the professional services to be performed is $33,250. This total Includes professional services plus travel expenses for an estimated seven trips to the Iowa City area. Iowa City's share of the cost will be $16,625. In-house staff time is not included In the cost estimates, As Iowa City's representative on the E9-1-1 Ad -Hoc Committee on Communications Consultants, I strongly support the recommendation to hire Ronald Vegemast Engineering, Inc. City of Iowa City MEMORANDUM Date: June 9, 1989 To: City Council From: Rosemary Vitosh, Finance DlrectorQwU [ > Joe Fowler, Parking Systems Supervisor -j A��—z Re: Recommended Preventive Maintenance - Capitol and Dubuque Street Parking Ramps The City of Iowa City financed the construction of the Capitol and Dubuque Street Parking Ramps ten years ago with Parking Revenue Bonds. Bond covenants require that the City set aside $60,000 each year for necessary maintenance and Improvements to parking system facilities. To preserve the structural Integrity of the Capitol and Dubuque Street Parking Ramps the City of Iowa City Parking Systems has carried out a program of preventive maintenance. Initial maintenance programs were directed by a report prepared by Walker and Associates of Minneapolis, Minnesota, original designers of both ramps. Beginning in 1985 the City retained the services of Shiva Haftery Engineers and Architects of Iowa City for a parking ramp evaluation and maintenance report. The repair work recommended by that report was done between 1985 and 1987. In April of this year we requested that Shiva Hattery examine both the Capitol and Dubuque Street Ramps to determine what maintenance was needed. This study was conducted under the direction of Dale Moore and Phil Larson. They have prepared a report detailing recommended repairs in both facilities. These repairs include action they feel is necessary at this time and a long range maintenance program. A brief summary of their recommendation for each ramp follows. CBgitol Street Perking Ram, The Capitol Street Parking Ramp is in 'Very good structural condilion.We found little evidence of visual deterioration of the concrete surfaces and did not identify any areas of Immediate structural concern.- Several areas of minor spelling were detected. High levels of chlorlde-Ion contamination (salt penetration Into the concrete decks) were detected in several areas of the ramp. This condition could result in concrete failure in the future if it continues. Core samples should be taken again in 1990 to determine if chloride penetration has Increased. At a minimum, the ramps will require resealing every three to five years. Based upon current data, resealing is recommended for 1991-1992. The anticipated life of expansion joints is seven to ten years. A program of major replacement was recommended beginning in 1992, This program will take three years to complete. Minor repairs are recommended this year for deteriorated sections of control joint materials and expansion joints. a E7 Dubuaue_Street Parkina Ram The Dubuque Street Parking Ramp "is in good structural condition." Several areas of concern were detected in the deck surfaces of the lower levels of the facility. Surface popouts and spelling continue to be a problem in several areas. The area of immediate concern is the north east end of level 2. Repairs have been made to this area previously. An epoxy overlay was applied during the summer of 1980. In addition spalls were repaired and resealed in 1985. At the present time the surface is scaled and water run off is being trapped. This has increased the chloride -ion content in this area to the level that action must be taken to prevent contamination of the structural steel. To restore the east end of level 2 Shiva Hattery recommends that we remove the top 1/2" of concrete and replace it with either an epoxy grout or a dense concrete, This work should be performed during the 1989 construction season. The deck surface of the 4th level, east end, and the 2nd level, west end, also show signs of spelling. These areas will be reevaluated in future years to determine if they also warrant surface removal and replacement. In addition to the surface repair It is recommended that steel connection points on the expanded decks be repainted at this time to prevent rusting, a cracked drain pipe be replaced, and repair work be done on spelled concrete and to deteriorated expansion Joints. Concrete core tests showed high levels of chloride -Ion contamination in the scaled concrete area of Level 2, while all other readings were relatively low. it is recommended that core samples be taken again in 1990 to determine N chloride penetration has Increased. At the current time, resealing is recommended for 1990. The estimated cost for the repairs necessary at this time is $77,000. This Includes the following: Recommended 1989 Repairs Capitol Street Parking Ramp: Spelled Concrete $ 800 Control Joints repair 4,000 .Expansion Joints repair 1.500 $ 8,100 Dubuque Street Parking Ramp: Spelled concrete $ 500 Expansion Joints repair 1,500 Connection plates modification 7,500 Drain pipe repair 500 i Concrete restoration, Level 2 East 54.000 54.000 $70,100 Contingency 8.900 TOTAL MM 3 In addition, the cost for Shiva to prepare bid documents and oversee the project is $9,500. Funding is available in the FY89 budget to complete the repairs recommended at this time. $100,000 has been budgeted in the Improvement Fund in anticipation of this report. Shive- Hattery's report also provided a future repair and maintenance program for the two parking ramps (See Exhibit A). This would phase-in the remaining concrete restoration in the Dubuque Street Ramp, and for both ramps the reapplication of deck sealers and the replacement of all expansion and control joints. Please note that these estimated costs do not Included engineering fees. The periodic evaluation of the parking ramps and their repair is necessary. Both ramps are structurally sound at this time, but repair and maintenance expenses are expected to increase each year as the structures age. /sp I' i "I I 3 In addition, the cost for Shiva to prepare bid documents and oversee the project is $9,500.

Gilbert Iowa City 52245 5 June 1989 Dear City Council Members: First, I want to say how pleased I am that action was finally taken against the properties of Miriam Young. Her penalty was much too small, however, and will do nothing to prevent other landlords from similar inconsiderate behavior. I rented an apartment from that woman in downtown Iowa City in 1971-72, and I'm sorry to see that she hasn't changed in the least. Anything that the city can do to prevent land- lords from turning neighborhoods into eyesores is appreciated. Second, I'd like to add my negative response to the re -zoning of the property that is destined to become a Wal-Mart. I know that this will win final approval, and I'm sure your intentions are honorable. However, I find it hard to believe that you don't, deep in your heart and mind, have doubts about ..the damage that Wal-Mart will do to what is currently a thriving .retail market. Specifically, I want to address two comments that I have heard several times from Council members: "Wal-Mart will attract shoppers from the small towns near Iowa City." I contend that those shoppers al- ready come to Iowa City to shop. Heaven knows, if discount shopping is what they want, they have plenty of discount shops to choose from already. "Wal-Mart will keep Iowa City shoppers from going out of town." Hogwash. The items sold by Wal-Mart will not differ 'enough from the other discount stores to keep people in town. Do Iowa Citians really need to leave town to do discount shopping?! I don't think so. Though we do 951 of our shopping here, when we do leave town to shop elsewhere it's to find unique things we can't find here --like furniture that isn't like everyone else's, or clothing for women over the age of 21. Or, for achange of scenery, to combine shopping with a movie or dinner somewhere new, or as part of a rendez- vous with out-of-town friends. People go out of town to shop for lots of reasons --but Wal -Hart, I'll bet, isn't -one of them. Someday, you'll say "Whoops! Guess we goofed on that decision." And it will be too late.�� P Mayor's Youth Employment Program 410 Iowa Avenue • Iowa City, IA 52240 • 356-5410 YOU ARE CORDIALLY INVITED TO ATTEND THE 2ND ANNUAL MAYOR'S YOUTH PIZZA PARTY Godfather's Pizza Parlour Corner of Washington and Dubuque Sts.

E . The era from the end of the Civil War to World War I is often considered The Golden Age of American Railroading. Before World War I, railroads were supreme and had little competition from other forms of transportation. Trackage increased from 35,000 miles in 1865 to 254,000 in 1916. The period was also one of technological innovation, consolidation of smaller lines into larger roads, and the rise of labor unions. Materials have been drawn from holdings in the Special Collections Department and the Main Library. The exhibition will be on view in the North Lobby, Main Library, from June 21 through August 11, 1989. H. Shelton Stromquist is an Associate Professor in the Department of History of The University of Iowa and the author of A Generation of Boomers.

This Information should be helpful In your questioning and general comments concerning my performance appraisal. The memorandum is self-explanatory. tp3-6 I i i i I I 1 i City of Iowa City MEMORANDUM Date: May 25, 1988 To: City Council From: City Manager Re: City Manager Performance Review I have attempted to prepare evaluation information which will hopefully assist the City Council in conducting my annual performance appraisal. In preparing the attached evaluation information, I met with some difficulty in designing a weighted criteria, that is some type of numerical system to determine whether criteria are being met. I purposely avoided the weighted criteria and have developed information which is more general in nature and hopefully by way of your notes and comments will be helpful as a performance review instrument. Evaluation is obviously a touchy subject, whether it is an evaluation of some type of a product or an individual. Traditionally, personnel evalua- tion has often been a critical and/or negative look at an individual's performance rather than the process of developing and improving relation- ships between the employer and the employee. Evaluation is a critical look at what an employee has accomplished during a given period of time, but also I believe it is a communication process, thereby allowing a method of discussion apart from the more formal decision-making process. Despite the close working relationship between the City Manager and the governing body, opportunities for personal discussions are very rare. Through regular evaluation, I believe we can begin to learn more about what everyone is doing, what everyone expects from the other, and what are the strengths and weaknesses in the relationship. Before beginning an evaluation, I think there are a number of basic prin- ciples that need to be understood to make the process successful. Those principles are as follows: /10 rA i. An evaluation must have a defined purpose. Evaluation is an opportu- nity to discuss and improve upon the working relationship between the governing body and the City Manager as well as to help define goals and objectives for future performance of the organization. We cannot assume that everyone understands the official purpose of an evaluation and, therefore, we need to take opportunities to identify just what each would like to see secured from this communication process. 2. The evaluation should begin with a mutual agreement and acceptance. Ideally, I believe the evaluation process is a joint undertaking, which means both the governing body and the City Manager want to do it and have a hand in figuring out how it should work. By working on it together, and coming up with mutual understandings, I believe we can meet the overall goals of improving performance and maintaining commu- nications. 3. The evaluation process should be regular. I believe that as the City Manager and governing body we have gone a long way toward making the evaluation a standard of performance in the relationship between the Manager and the City Council. If it is not done on a regular basis, I believe it could become ineffective, possibly threatening and suspi- cious. 4. The evaluation should be open and constructive. When the evaluation process is actually underway, it is a process of sharing - talking openly. It is important in the process we try not to waste our time on the areas that a City Manager can do very little about, such as a City Council's disagreement with a personality quirk in an individual employee. This is not to say that personality quirks can and do not often affect job performance, but we must be able to identify in this process we are trying to deal with the actual work and not an individ- ual's personality. If, however, the personality, such as erratic behavior of an employee continues, it can and should be a subject of discussion. I believe at all costs we should recognize that we are in the process of communicating and not one of combat. /0006 ■ 3 5. The evaluation should be based on objective criteria. If the criteria for evaluation is well thought out and positive, I happen to believe we will end up with a positive and effective evaluation. The best evaluation criteria for a position such as the City Manager is crite- ria that is comprehensive and identifies skills, achievements and results. In other words, if you try to review and evaluate every dimension of your chief administrator, it may be difficult to come up with objective criteria, specifically when the chief administrative officer is required to wear many hats. I think we each need to think about expectations and then expand on those expectations. 6. The evaluation should lead to positive action. To be effective there must also be a follow-through to successful evaluation. You need to it make sure in your planning that action steps are required on the part I ' ,E of the City Manager and/or the governing body. It is critical in each of the follow-up evaluations we ask ourselves "How did we dol" An evaluation should lead to opportunities to better the organization and the relationship with the governing body.

Washington St.City, Iowa 52240Joseph Company Project; Highway 1, Iowa City Mr. Atkins:1 am in receipt of your letter o£ June 1, 1989, requesting we agree to pay part of the cost of installing a traffic l On Highway 1 at Carousel Motors if one should prove ary within the next three years. We have had an unity to analyze this request, and in this letter will ize our position on this matter. s the City staff can attest, we have tried to be as cooperative as possible in developing this center to foster the City's best interests. For example, not only have we agreed to bear 100% of the cost of installing the traffic light at the main entrance of our project,, but we have also agreed to pay the cost of installing the roadway on the east side of our project as a secondary entrance. It is likely that future developments to the north of Highway l will benefit from the light at our entrance, and future developments on the Airport property east and south of our new eastern roadway will benefit from that roadway. Both of these improvements will be quite costly to install. However, we have not asked for future developments that benefit from these improvements to reimburse us for a portion of the costs of installing these improvements. Instead, we have agreed to bear the entire economic burden ourselves. We do not believe a light at the Carousel entrance on Highway 1 will be necessary because of Our project. As such, we do not feel we should be required to contribute to the cost of signalizing this intersection, especially since we are bearing the entire cost of the signal on Highway 1 and the eastern roadway. Nonetheless, we have always been flexible with the City, and needless to say will do so again if required on this matter. 1NIVERSITY SQUARE Fnunla en o. .�.

However, in this case, we will ask the City to assist us in arranging a program which will allow us to recoup a portion of the costs of the signal on Highway 1 and the eastern road, from future developments that also utilize and benefit from these improvements. IWe will be happy to discuss this matter with you and the City Council, and answer any further questions you may have. We look forward to hearing from you. MJW:7J Yours ve trul , I* 1- ��w J.

Fringe Area Policy Agreement between Johnson Co, and Iowa City Neighborhood Open Space: Methodology INTRODUCTION j A comprehensive plan Is a compendium of policy statements which deals with various facets of a community's growth and development. The plan looks to a definable future and attempts _ to project the community's rate of growth and image. The plan and its policies are the framework for public and private decisions relating to the maintenance and growth of the city. Once adopted, the plan provides notice to present and future governing bodies and to the citizenry of what to expect in terms of such Issues as land use, economic development, the construction of public facilities, the approval of development projects, the availability of public recreational opportunities, the general location of schools, and the possible future costs of . living in the community. The comprehensive plan also serves as a legal basis for development regulations and decisions. In 1978, Iowa City adopted a Comprehensive Plan which has served as a guide for Iowa City since that time. The 1978 Plan was adopted after extensive community involvement through '-! a citizen's coordinating committee, surveys, and neighborhood discussions. The goals, ! objectives and policies adopted in that Pian are carried forward, as amended, in the 1983 ( Update and in this Update. The Update completed in 1983 was the first of periodic reviews which are intended to take place every three to five years. The 1983 Update was concerned _ primarily with land use Issues, particularly the timing or sequencing of development as it relates I to constraints in the City's sewer system. The 1989 Update is the second periodic review and again evaluates the community's sequence of development as circumstances have changed _ since 1983. With this Plan Update, a new format is used in an effort to compile, in a single document, the development policies adopted and amended since 1970 and to have a plan which can be easily reviewed and can be changed when appropriate. It is also the intent of the City to refocus long-range planning efforts by engaging in a continuous process of long-range planning rather than the traditional approach taken in the past of plan adoption, and periodic — review and revision. Every effort will be made to strike a balance between the predictability _ of a static plan and the flexibility of a plan which responds to a vital community. Long-range planning will be done annually and will involve the participation of various City departments, I — boards, commissions and the Council, community leaders, members of the development i— community and the public in general. The 1989 Plan begins with a summary of the policies adopted for various aspects of the City's growth. Guidance for the development of specific areas of the City are Included in the recommendation sections of the Area Studies at the end of the Plan document. Following the -- policy summary are discussions of the rationale for particular policies, background informa- tion, a sequence of development which projects timing of growth in given areas of the city, and discussion of the ways in which this plan can be Implemented. Specific implementation measures will evolve from the Plan and be adopted by the City Council over time. I- i_ i-7 POLICIES The policies listed below were adopted as part of the 1978 Comprehensive Plan and have been revised by the 1983 and 1989 Pian Updates. These policies continue to govern the actions of the City. Many of the policy statements listed under a specific heading are applicable in different topical areas. It is critical, when using these policies to guide decisions, that all relevant policies to an issue be considered and balanced in the decision-making process. Land Use Policies a. Existing Land Use j 1. Encourage the relocation of incompatible and obsolete land uses. 2. Re-evaluate zoning districts in neighborhoods where identified conflicts exist. 3. Zone undeveloped land areas adjacent to existing uses in such a way as to maximize compatibility. 4. Acquire and redevelop areas where change is imperative to residents' health and safety. b, Soils. Topography. Vegetation _ 1. Utilize woodland areas, flood plains and creek headwaters as positive locational criteria for parks and open space, and similar low intensity land uses. 2. Encourage the use of Planned Developments in areas where soils, topography, or vegetation are limiting factors. C. Core Areas 1.

From 1970 to 1980, Iowa City experienced slow but steady growth at a rate of approximately 500 people/year. From projections done for 1990, 1995 and 2000, It appears that the rate of growth may diminish to result in a loss in population by the year 2000. Iowa City's population is unique in that there is a significant number of college students residing here. In calculating population projections, the student and non -student populations were separated and projections were made for each group. Projections for the university population were obtained from the University of Iowa Office of Academic Affairs. The projections for the general population were made using the cohort -component method. This method is the most commonly used and accepted technique for making local area population projections. The method assumes that past trends in the "components of change" - birth, death and migration - will continue Into the future. If the projection period is not too far Into the future, then this assumption is not unreasonable. Summarized below are population estimates and projections for the student and non -student segments of the population. Summary: Projected Iowa City Population E Estimated Non -student Student Population Population 7ota1 Iowa City Population, 1980 census 32,209 18,299 50,508 Estimated Iowa City Population, 1985 32,492 23,286 55,778 Projected Iowa City Population, 1990 32,661 21,845 54,506 Projected Iowa City Population, 1995 32,029 18,859 50,888 Projected Iowa City Population, 2000 30,836 19,201 50,037 The projections for the year 2000 are subject to the greatest degree of error since the time period forecasted is farthest from the original base data collected In 1980. New data collected In the census of 1990 may reveal that Iowa City's population has remained relatively unchanged or has in fact, Increased. For the purposes of this Plan, a slow rate of growth of 100 people/year has been assumed, E DEVELOPABLE LAND ANALYSIS Knowing the amount and location of undeveloped land within the corporate limits is useful in determining whether adequate space exists to accommodate future urban growth and in identifying areas where development pressures may arise. While many factors come into play in planning urban land uses, development of any land requires access to sanitary sewer service. This analysis is framed, therefore, in the context of availability of that service. Once the location of developable land is determined, the projected timing of development will be proposed based on a number of factors including the availability of sewer service. Available Acreage Of approximately 13,950 acres within the present corporate boundaries, about 4,450 acres remain undeveloped. Except for vacant lots within the Business Development, Inc. (BDI) industrial suvisio bdin, this number does not Include any land platted prior to January, 1988, that remains undeveloped. Over 92% of the undeveloped land, or 4,120 acres, is ultimately sewerable by means of gravity -flow sewers. Certain Infrastructure improvements, including construction of a new wastewater treatment plant, will be necessary to achieve full develop- ment. Approximately 325 acres, or 7% of the undeveloped land within the corporate limits, Is located in watersheds that drain away from the city and will, most likely, be dependent upon the installation of mechanisms that pump sewage into the municipal disposal system. Approximately 30% of the entire city, then, remains undeveloped and eventually serviceable with gravity -now sewers. Based upon existing zoning, about 73% of the sewerable undeveloped land is expected to develop for residential purposes, 21% for commercial use and 6% for industrial development. About 2,808 acres are zoned for single-family residential use while 193 acres are designated for multi -family residential development. Based solely on unconstrained sewer cepscIty, this amount of land could accommodate 31,830 people (Iowa Wastewater Facilities Design Standards: single-family - 3 to 3.5 units/acre, 3 people/unit or 10 people/acre; multi -family (medium density) - 4.5 units/acre, 3 people/unit or 15 people/acre), At the present rate of growth, the city has adequate developable land to serve growth needs well Into the future. By applying the 1983 Comprehensive Plan Update growth rate projection Of 500 Persons/year, It appears sufficient developable land exists for about 64 years of growth. Long-range population estimates project a loss in population due to a reduction in University enrollment and a decline in the non -student population. Even at a hypothetical growth rate of 100 people per year, Iowa City would have enough sewerable undeveloped land within its existing corporate boundaries to enable 318 years of population growth. All in all, sufficient undeveloped land exists within the City to accommodate the Increase in population anticipated within the 20 year planning period of this Comprehensive Plan Update, I", i -- Sewer Capacity This analysis assumes that solutions to certain sewer capacity problems will be accomplished r within the 20 year timeframe of this Update. Easing certain existing development constraints is expected to occur with construction of a new Water Pollution Control Plant (WPCP) south of Iowa City, improvements to sewer lines, and with upgrading the existing sewer plant. It is the intent of this analysis to Identify developable areas of the city within the confines of the { vj proposed sanitary sewer Improvements and without a commitment to additional municipal f!; capital Improvement funding beyond that provided for in the wastewater system Improvements plan. Lilt Station Policy. This analysis focuses on the developability of land which is sewerable by I means of a gravity -flow, system. As has been noted, approximately 325 acres of land generally �? located in northern Iowa City and in the southwestern part of the community are in watersheds Ll that drain away from Iowa City. These areas will, most likely, be dependent upon the installation of mechanisms that pump sewage into the municipal disposal system. Where lift i stations are necessary, the City prefers the use of mechanisms that are designed to serve an entire drainage area and not a limited number of lots within a subdivision. This design consideration reduces the cost of operating and maintaining the City's sewer collection system f' and makes the use of lift stations more cost-effective. The 325 acres which will require a lift station are not included in the developable land totals; however, these acres do supply additional land within the corporate limits for future growth, Proposed Improvements. The wastewater system Improvements plan proposes upgrading the existing "north" plant, generally located Immediately east of the Iowa River between J iOrkwood Avenue and Highway 6, to Increase Its capacity from B million gallons per day (mgd) to 9.4 mgd and constructing a new plant south of Iowa City and east of the river. The "south" plant, would have a capacity of 5 mgd. In conjunction with these improvements, a new Interceptor sewer is planned in southeast Iowa City, and a series of relief sewers within the Ralston Creek watershed and on Benton Street are expected to Improve certain existing capacity constraints. The net effect of these Improvements is to generate a proposed excess sewer capacity of 2.42 mgd. The City's Public Works Department estimates that, based upon average per capita use, this excess capacity could serve a 12,475 person Increase In the clty's population. However, this estimate does not consider contributions from infiltration and inflow as a result of an aging and expanding sewer system. Without consideration given to this component and to commercial and Industrial sewer needs, at a hypothetical average population Increase of 100 people per year, this excess capacity could accommodate almost 125 years of growth. As noted, this estimate does not consider the impact of future industrial growth. Additional j Industrial development within Iowa City will reduce the amount of residential population that can be served by the proposed Improvements. Existing Iowa City industries are typically dry uses that do not demand an excessive amount of sewer service, If new Industries locating within the city are characterized as wet versus dry uses, a considerable portion of the proposed — excess sewer capacity could be consumed by these uses. Based upon the type of Industries i 10 I— r that have historically located within Iowa City, however, the excess capacity of the improved sewer system is expected to accommodate both residential and industrial development within the community well Into the future. Although the upgraded and expanded sewer system will relieve several development constraints and is expected to accommodate significant growth within the community, it must be " emphasized that the proposed Improvements will not allow full development of the city. Additional commitments to relieve limitations within individual sewers and to expand the capacity of the proposed sewage treatment plant would have to be made to permit full development of land within the existing corporate boundaries. Impact of Proposed Improvements. Within the confines of the proposed sewer system Improvements, the extent to which areas of the city may develop will be limited by restrictions within individual sewers serving unplatted land. In conjunction with the 1983 Update of the City's Comprehensive Plan, the Engineering Division completed six sewer capacity studies in which density of development was determined for unplatted land within the service areas. The studies consist of determining the most restrictive sewer sections, the existing flows and the corresponding excess capacity in the trunk sewers. Using a peak flow average of 300 gallons per capita per day for residential development and developable acreage totals, the people per acre development potential for the unplatted areas was determined. To date, these studies have not been evaluated in the context of the proposed wastewater system improvements. Development in areas of the city with sewer constraints that will not be alleviated with the proposed sewer system Improvements will continue to be limited by those restrictions. On the other hand, the Impact of the proposed improvements on the developabil- fly of land affected by those Improvements is difficult to assess until the new system is on line and actual flows can be measured. The following discussion describes municipal sewer service capabilities within specific areas of the city and Identifies those areas that will most predictably benefit by the sewer system Improvements. Assumptions The following assumptions establish the parameters used to determine the sewer service capabilities that affect development of land within the city. It should be noted that these assumptions simply provide a basis from which to reasonably estimate developable areas; any changes in the following assumptions will change the number of developable acres available. The wastewater system Improvements, at current design specifications, will be completed by June, 1991. The north plant will be upgraded by November, 1989. Construction of the south plant, the outfall sewer leading from the south plant to the Iowa River, and the Snyder I — Creek segment of the Southeast Interceptor Sewer are expected to be completed by August, 1990. Phases I and II of the Ralston Creek segment of the Southeast Interceptor will be completed by June, 1991. - The existing sewer between Dubuque Street and Prairie du Chien Road will not be upgraded to a larger size. 11 /toV The "Oakes lift station," required for the development of portions of land east of Prairie du Chien Road, will not be built. Municipal funds will not be expended to upgrade a segment of the 10" main in the Willow — Creek Trunk Sewer to a larger size. . The "Eicher lift station," required for the development of portions of land in southwest Iowa City, may only be built in conformance with the City's out -of -sequence development policy. - Currently, sewer lines over eight inches in diameter require capital improvement funding; therefore, land which requires oversized lines not included in the Wastewater System f� Improvements Plan is not included as developable. - Land which may be sewered with eight Inch line extensions provided by the developer is j Included as developable. ` M . Land platted prior to January, 1988, which has not yet been fully developed is not included i t as undeveloped land. - The surcharge problem in the Rundell Street Trunk Sewer, Jefferson Street Relief Sewer and the Outfall Relief Seweraka "the horseshoe" sewer) will be resolved with construction of the Southeast Interceptor Sewer System. Annexation/deannexation of land for residential uses is not contemplated. Potential Growth Areas J East Area. The pivotal Issue affecting future development of the East Area is the impact of the proposed sewer system improvements on resolving wet -weather surcharging conditions in the Rundell Street Trunk downstream from the study area and in the Lower Muscatine Trunk, _ conditions that have been a deterrent to full development of the area. Construction of the WPCP and the Southeast Interceptor System are expected to alleviate sewer capacity problems i - in this area. The approximate 130 acres available for development south of Muscatine Avenue plus the Industrial park would be developable with city sewer service at a density equivalent to 13 people/acre (1983 Update estimate). This assumes that the Village Green lift station will ibe expanded to accommodate development within the Village Green subdivisions. I J Developable land north of Muscatine Avenue and east of First Avenue is serviced by the Southeast Trunk Sewer. With completion of the Southeast Interceptor relief lines and upgrade of the 18" South Branch Dam Sanitary Sewer, there exists enough capacity to provide sewerage to all of the unplatted lands within this part of the East Area. The development ipotential reaches 88 people/acre for the land lying along Scott Boulevard between Muscatine and Rochester avenues and 34 people/acre for an area south of Rochester Avenue and west of Amhurst Street; the lower density in this area is due to a local restriction in an eight Inch i line. The South Branch Dam Sanitary Sewer would have to be further upgraded to allow any (_ development beyond the existing corporate boundaries. No commitment to make these additional Improvements is proposed. I 12 I V � /09/ i 17 Inner CHy. This area is adequately sewered to permit redevelopment even at an increased density. I " North Area. The 124 acres west of Prairie du Chien Road, within the present city limits, are within the Immediate watershed of the Iowa River and could be serviced by the existing Bjaysville Lane Sewer which empties into the River Corridor Trunk. The 119 acres east of _ Prairie du Chien Road are in the Rapid Creek watershed that drains north, beyond the Iowa City corporate limits. To serve this eastern area, a lift station is required to bring the flowage Into the serviceable watershed to the west. To do so, however, decreases the capacity in the _ Bjaysville Lane line available for the development of land to the west of Prairie du Chien. ' I The 1983 Comprehensive Plan Update estimated that the remaining capacity in the Bjaysville Lane Sewer translates to a 12 people per acre development potential when considering the undeveloped area within the current city limits and the natural drainage basin served by this 1 I sewer. If, on the other hand, all the undeveloped land in the North Area is serviced without future capital improvements, the overall density of development west of Prairie du Chien which can be served is, according to the 1983 Update, decreased from 12 people per acre to 6 j people per acre, a density which is more restrictive than the densities proposed in the current Zoning Ordinance for that area west of Prairie du Chien. The 1983 Update suggests that, if development of the area is to be encouraged at densities higher than 6 people per acre, the sewer serving this North Area should be upgraded to 24 inches to accommodate long-range growth projections. I More current information from the City's Public Works Department, however, indicates that, in wet weather conditions, the Bjaysville Lane Sewer surcharges. The 12 people/acre development potential estimated for the western portion of the North Area is, therefore, = overestimated. To allow residential development at urban densities within the portion of the North Area in the natural service area of this sewer, the sewer must be upgraded. While the 1983 Update suggests that, since a proposal on the part of a private developer to construct a lift station to serve the land In the North Area located outside the service area has not materialized, the capacity exists in the Bjaysville line to permit full development In the west at 12 people per acre. More recent Information Indicates, however, that development of land within the sewer's service area is constrained by its inadequate size regardless of development i to the east. J Northeast Area. Extension of a 21 -Inch trunk line along Ralston Creek as part of the North Branch Ralston Creek Dam project has made approximately 200 acres in the Northeast Area, --- generally located adjacent to the north and east borders of Hickory Hill Park and the Ralston Creek slormwater detention facility, sewerable. While capacity in the Northeast Trunk Sewer which services this area is not a constraint, development has been hindered, in part, by a surcharge problem downstream in the Jefferson Street section of the "horseshoe" trunk sewer. Proposed wastewater system Improvements, Including construction of the Southeast Interceptor Sewer, will relieve the surcharging condition experienced In the area served by the "horseshoe" sewer. The proposed Interceptor sewer system and plant Improvements could accommodate the sewage treatment needs of the 1 11 remaining 700 acres of sewerable land in the eastern half of the area; however, additional capital improvements in the form of trunk line extensions will be needed for development to occur. Peninsula Area. Presently, approximately 60 of the 530 acres within the Peninsula Area are _j sewerable without major capital Improvements. These sewerable areas are located adjacent to existing development on the Peninsula and would, therefore, permit compact and contiguous growth. Capacity for most of this developable area is unconstrained as a 36 -inch line extended Into the Peninsula Area ties in directly to the 36 -Inch River Corridor Sewer. The short-range development limitation of the Peninsula will not be alleviated with the proposed construction of a new WPCP. Construction of a sewer extension to serve the remainder of the Peninsula is not scheduled to occur concurrent with the WPCP construction and is not anticipated in the short-range, Full development of the Peninsula can only occur following I extension of a trunk line westward from its present terminus near the Taft Speedway/Calibria Court intersection. f ( South Area. While construction of the WPCP is Intended to solve many city-wide sewer restrictions, the South Area will not benefit substantially from projected improvements to the system. Present sewer design does not call for extending a trunk line to the South Area ri concurrent with construction of the WPCP, That decision, therefore, restricts development J within the city limits to the area which is presently sewerable. Full development may occur I _ only if a trunk line is extended westward into the South Area from the proposed Southeast Interceptor Sewer. J ^ Southwest Area. The capacity of the Willow Creek Trunk Sewer is limited by a bottleneck situation which effectively limits sewerage capacity at the present time. The bottleneck situation Is the result of an 18 -Inch line flowing into a 10 -Inch sewer line. Although sewerage from i_ approximately 438 acres of undeveloped land could naturally drain to the 10 -inch trunk line, this line has the ability to accommodate development at only two people per acre for this entire area due to current constraints, Two people per acre is an extremely low density for urban development and would result in Inefficient use of public services. No public commitment of funds to relieve this constraint or to remedy restricted sections of the Southwest Interceptor Sewer are proposed in the short-range. As a result, full development of the Southwest Area is not anticipated in the short-range; development may occur on approximately 95 of the available 438 acres at a development density of about 11 people per acre. While it is anticipated that much of the Southwest Area will develop for residential uses within the long-range, residential development should be confined to areas east of U.S. Highway 218 in the short-range. Undeveloped land east of this highway is in closer proximity to existing development and, therefore, closer to the services needed to support that development. The net effect of proximity to existing development Is that the cost to the City and to current City residents of providing the required services Is less. For this reason, because sewerable, undeveloped land is available east of the highway, upgrading sewer system constraints in the — Southwest Area to accommodate development west of the highway is not appropriate. 14 i- In January, 1988, the City Council amended the 1983 Comprehensive Plan Update by Including — a policy which addresses out -of -sequence development. The basis of this policy is to permit development out -of -sequence with the City's phased growth management policy provided that j development approximates the efficiency of development upon which the growth management policy is based. This is achieved by requiring non-sequent development to absorb all of the costs associated with that development, including costs typically subsidized by the City. In the same month, the City Council conditionally rezoned approximately 85 acres of a tract iknown as Southwest Estates from ID -RS and RR -1 to RS -5 in conformance with the out -of - sequence development policy. Subsequently, about 22 acres of this rezoned tract were subdivided Into 55 low-density, single-family residential tots. As a result, until existing sewer constraints are relieved in the Southwest Area, residential development opportunities east of Highway 218 are diminished. Because the balance of the Southwest Estates tract lies within a watershed that drains away from Iowa City's sewer system, it cannot physically develop at urban densities without a lift station to pump sewage Into the municipal sewer system. While the maintenance requirements of lift stations are not cost-effective to a city if such a system serves only a few properties, that system is more cost-efficient if a large area is served. At such time as the balance of the Southwest Estates tract is developed, then, a lift station of sufficient capacity to serve °j Southwest Estates and property west of Slothower Road which is located within the corporate limits and which drains toward the subject tract should be employed. Sewage from this entire area would then be pumped to the collection lines leading to the City's sewage treatment plant. i This assumes, however, that the municipal sewage collection and treatment facilities can accommodate the Increased demand. Constraints within the Willow Creek Trunk Sewer and the Southwest Interceptor Sewer preclude full development of the Southwest Area. Unless development of the eastern portion of the Southwest Area alone necessitates Improving the sewer system, the City will make no commitment of public funds to relieve existing constraints to full development of the entire Southwest Area. Any residential development occurring west of Highway 218, with the exception of the already platted Hunter's Run Subdivision, must comply with the City's out -of - sequence policy, including setting aside a prorated amount of funds toward Improvements required within the sewer system serving the Southwest Area. Northwest Area. The topography of the Northwest Area has discouraged its development. Of the approximately 1,100 acres in the Area, none are presently served by existing sewer lines, Any trunk lines extended Into the Area, which would be funded In large part by the developer, would most likely utilize the Hawkeye lift station to pump sewage from this area into the Willow Creek watershed which drains toward the existing municipal sewage treatment plant. While this lift station has enough reserve capacity to allow full development of the Northwest Study Area, development is constrained by the lack of capacity existing downstream In the Southwest Interceptor Sewer. The Southwest Interceptor Sewer, therefore, determines the development potential of the Northwest Area, 15 /,Of/ Before full development of the Northwest Area may take place, sewer lines from the Hawkeye lift station must be extended to the area and the Southwest Interceptor Sewer must be upgraded to eliminate existing constraints in that system. Because problems in the Southwest Interceptor Sewer may have to be remedied regardless of development of the Northwest Area, the critical factor in determining the availability of sewer service to this Area rests in the extension of the trunk lines from the Hawkeye lift station to serve the developing area. MAJOR FINDINGS 1. At the current rate of growth, sufficient developable land exists within the corporate limits to accommodate residential growth needs well beyond the 20 -year timeframe of the plan. 2. Constraints within the "horseshoe" sewer will be alleviated by proposed wastewater facility Improvements and will enable full development of the East and portions of the Northeast areas. 3. Growth areas which are not dependent upon proposed improvements to the City's wastewater treatment facility are generally located in the northern and western parts of the city. 4. Potential growth areas in the north may aggravate problems in the Bjaysville Lane Sewer by adding additional flowage to lines whose capacities are currently exceeded during wet weather. This problem may dictate that development of the North Area be postponed until the surcharge problem can be alleviated. S. Growth areas which are dependent upon upgrading segments of the Southwest Interceptor Sewer are the Northwest Area and the portion of the Southwest Area west of U.S. Highway 218. 6. The extension of trunk sewer lines will determine the rate of development of the South and Northwest areas and the eastern portion of the Northeast Area. 16 i II I I ^+ DEVELOPMENT SEQUENCE i A land use development sequence schedule serves as a policy guide for public decisions I relating to the growth patterns of private development. Sequencing development is a growth r management technique that allows the City to anticipate and phase the expenditure of funds to provide the municipal services and the public share of capital improvement costs needed to accommodate new development. This technique prevents overloading existing public r facilities and services and provides a framework in which to program and budget the f { ' improvements needed for existing and proposed development. The development sequence schedule is intended as a guide for establishing a capital improvements program that will predictably and cost-effectively allow the City to expand in an efficient manner while, at the l i same time, allow developers an opportunity to anticipate the community's future growth pattern { and to plan accordingly. �j A sequence of development for residential land uses is presented in this Plan in Table 1. r Commercial and industrial uses are not Included within this development sequence proposal. The timing of development for these uses will be determined, to a great extent, by economic factors beyond the City's control. The timing of development for these uses should, nevertheless, be determined in the context of a given area's capability of supporting proposed commercial and industrial uses. Future studies are expected to analyze commercial and Industrial development within Iowa City and to offer a development sequence schedule for j 1 these uses as well. "1 Assumptions To determine the sequence of residential development, the following assumptions are made. -, These guidelines were used to analyze the various areas within the City and to derive a development sequence schedule appropriate for the community. -7 1. Proximity to existing development governs the sequencing of development. 2. Areas which can accommodate the greatest population for the least cost in capital 7 Improvements (i.e. available sewer capacity, street accessibility, existing school capacity, etc.) are considered highly developable. 3. Extension of sewer and water services and streets at the least public expense adds to the development potential of an area. -; 4. Major capital Improvement requirements in an area detract from Its development potential. '1 S. Proposed wastewater system Improvements are complete. i- i 17 �J i �0t� I i j Methodology r i i.� r J This Plan divides the community into various study areas. To determine the appropriate sequence for residential development, undeveloped areas within each study area that are expected to develop for residential purposes, were further grouped on the basis of characteris- tics that influence their developability. Each of the 20 residential subgroups thus Identified were evaluated in terms of the criteria listed in the following table. A portion of Fringe Area 5, the extraterritorial area east of Iowa City and Fringe Area 6, located south of Iowa City, were also evaluated. Proximity to existing development, infrastructure and municipal service availability and physical/locational characteristics of a site were the factors taken into consideration. A weighted score was assigned to each of the 20 residential subareas located within the corporate limits and to the two fringe areas. A low score Indicates a higher development potential and Implies that the area can develop in a manner that fosters cost- effective, compact and contiguous urban growth.

I 20 y..y' "t., J n �i u Findings The development sequence schedule reveals that the City has 436 acres of land within close ment Proximity existing lc presently developable residential y sgnificantcaptal impro ments.This stphae of the development sequence could support a 6,390 person Increase in the Iowa City population. While population estimates project the City may lose population by the year 2000, at the hypothetical growth rate of 100 persons per year, the City currently has sufficient land to accommodate over 63 years of residential growth. Within the 20 -year timeframe of this Comprehensive Plan, then, yearsuffics undeveloped residential land exists within Iowa City to accommodate the population anticipated nt In that period. At an average development density of 15 people per acre, the 2,904 acres of undeveloped residential land located within the existing corporate limits and identified in Phases II and III could support 43,560 residents, if the City were growing at the rate of 100 people per year, this land could support over 435 additional years of growth. Out of Sequence Development Policy From time to time, certain factors may encourage private developers to develop tracts of land out of phase with the development sequence determined to be appropriate for the City and Illustrated in Table 2. Those developments will require the extension of municipal services In a manner that is Inefficient and not anticipated in the City's capital improvements program. To approximate, as much as possible, the cost-effectiveness of development upon which the City's growth management policy Is based, out of sequence development would be required to absorb all of the costs associated with the development, Including costs typically subsidized by the City. Costs customarily paid by the City may be recouped at such time as sufficient intervening development occurs to resemble the cost/benefit balance upon which sequential development is based. ANNEXATION POLICY Annexation is the process by which land abutting an existing municipality is made part of that municipality. The prospect of future annexation is implicitly recognized in Iowa City's extraterritorial review of planning, zoning and subdivision activities within two miles of its existing corporate limits. The development policies for this extraterritorial area are set forth in the Fringe Area Policy Agreement between Johnson County and Iowa City. These policies offer some assurance that development within close proximity of Iowa City will proceed in a manner compatible with municipal development standards. That way, at such time as it is determined to be in the public interest to annex this territory, existing development within that area will conform with Iowa City development standards and practices. Cities generally annex land to provide area for growth, or for a particular public benefit such as controlling the development of land. The City, for example, may wish to annex land at major entrances to the community to control and direct the type of development that can occur there. The City may also annex land and furnish municipal services to that area as a means of providing readily available land to accommodate either industrial or commercial development. Whatever the motivation, annexation generally occurs when it is in the public Interest to exercise local control over a tract of land. Annexation is achieved either involuntarily (without the explicit consent or request of the owner of land to be annexed) or voluntarily (at the owner's request), Residential Growth Presently, approximately 4,450 acres of undeveloped land exist within the City to accommodate future growth. if an average residential development density of 15 people/acre (the ratio used for sizing sanitary sewers) and the 1983 Comprehensive Plan Update growth rate projection of 500 people per year are applied to the 4,120 acres of sewerable undeveloped residential land available, there is sufficient land area for about 123 years of growth. The Developable Land Analysis notes, however, that current population trends show that the City may be losing residents. By the year 2000, the Iowa City population may be slightly less than the 1980 Census count of 50,508. At a hypothetical growth rate of only 100 people per year, Iowa City would have enough sewerable undeveloped land within Its existing corporate boundaries to enable development well Into the future. With all other factors, such as the desirability of undeveloped land and property owners' inclination to develop, being equal, undeveloped land within the existing corporate boundaries appears to be capable of accommodating growth well Into the future. For reasons of providing area for expected residential growth, sufficient land exists within the community to accommodate new development; annexation of land for that purpose Is, consequently, not justified. 23 I Even though sufficient land exists to meet the overall residential needs of a city, annexation may sometimes be desirable to complete existing neighborhoods. A residential neighborhood unit is generally focused on a common facility such as a school and is delimited by the distance from the facility that Is walkable and unimpaired by physical barriers such as arterial _ streets which Inhibit interaction among the neighborhood residents. Typically this distance is a half -mile in any direction. By encouraging the development of complete neighborhoods, sufficient population exists to support the services required within that neighborhood and to make the provision of infrastructure and other municipal services cost-effective. As cities grow, i it is desirable, therefore, to annex land abutting an existing corporate limit where complete ' neighborhoods are permitted to develop. There is no justification, on the other hand, to annex land to establish new neighborhoods if suircient land exists within a community to accom- modate growth. Land Use Control i { Annexation of land may be a desirable option in areas where the City wishes to exercise greater land use control than permitted under the Fringe Area Policy Agreement. Control of " development beyond the corporate limits becomes necessary when there are specific municipal -� concerns that the County may not have the propensity or inclination to consider. In some instances, for example, the City may wish to exert zoning control along existing highway corridors or interchanges within close proximity to the City. This type of control allows the City to regulate the type of development permitted in a manner that does not detract from the development or redevelopment of properties within Iowa City, that does not burden local streets and other public facilities, that is sensitive to the environmental Interests of land within close proximity and that enhances the Image of the community. In Instances in which local control of development is desired, annexation, then, is the most effective means by which the City can protect its interests. Cost/Benefit Considerations There are municipal responsibilities and financial implications associated with annexation of land adjoining the City. The City must have the physical and financial capability of extending essential municipal services and benefits not formerly enjoyed by the residents of annexed — areas within a reasonable period of time. As a result, the direct and indirect public benefits of annexation should be measured and, at a minimum, these benefits should equal the cost of public services provided. The City should be cognizant of the Impact Its actions may have on inducing annexation _ pressures at the City's margins, The location of certain capital Improvements such as major roadways and sewer lines and the timing of those Improvements may create growth pressures _ in areas outside the community but close to those amenities. Capital Improvements which promote scattered development waste land, foster pressures to annex land where growth is not currently appropriate, and ultimately result in overextended city services which are a ... financial burden to the taxpayers at large. I - 24 i i i, '. i it I;: i FRINGE AREA POLICY r1 State enabling legislation permits a city to regulate the subdivision of land within two miles of its corporate boundaries. The extension of municipal powers beyond the corporate limits of a city into unincorporated territory is known as extraterritorial Jurisdiction. This extraterritorial Power authorizes a city to prescribe reasonable rules and regulations governing the development of land within the "urban fringe area." Fringe Area Policy Agreement In December, and ohnson �! that provided forrtthe IowaCity growth) and development of landentered lnto a withinland usethe two-milelextraterritorial fw Jurisdiction of Iowa City. Both jurisdictions deemed that the policies within the fringe area agreement were necessary to protect and preserve the area's natural and agricultural � resources, to provide for orderly and efficient development patterns, and to more effectively and .i economically provide services for future growth and development. On the basis of these objectives, the fringe area policy agreement set forth development policies for nine designated t1 ry areas within the urban fringe. P9 The icies d for the urban hichelesidentialtdevlelopm development Iseencou aged andrareas areasinagricultural differentiate etween areas in use se is preferred. Commercial and Industrial land uses are recommended, on only a limited basis, within the fringe area. r, Residential development is generally encouraged on land that is accessible by existing roadways capable of accommodating this use, in areas in which services can be efficiently and -1 cost-effectively provided, and in areas that are less suited for agricultural purposes. It is in the I Interest of the City that residential uses be restricted to certain areas within the urban fringe to concentrate residential development and, therefore, maximize the efficiency of services that must bultimatelyepresults Inoove overextended servcesScattered whl hresidential a financialburdenden t ment, ontheaother had, taxpayersnat large. All rezoning requests and development proposals are to be consistent with the development policies and design standards adopted for each designated area.

Subsequent to this action, the City and County reassessed the development policy for Area 4 and, in response to development pres- sures in the area, amended the policy to provide for limited residential development in that portion of Area 4 east of Highway 1. Efficient Municipal Service Extension i As noted, limiting residential development within Iowa City's fringe area to certain developing areas allows for the effective and economical provision of the full complement of municipal services a community must provide at such time as those areas are annexed. Concentrated residential development versus scattered development makes the extension of those services 71 more cost-effective. Once the pattern of development Is set by the layout of streets and lots, that pattern is established for perpetuity. It is in the City's best interest, therefore, to be aware of the permanency of land use decisions and to restrict residential development to areas of the urban fringe that are developing for residential purposes and that can be efficiently served with municipal services at some future point in time. Financial Inequities I Within the past few years, the City has witnessed considerable residential development within the portion of the urban fringe north of the corporate boundaries. Although the County reaps _I the financial benefits of this development via increased property tax revenue, there are few services the County provides the development and, hence, few costs the County must Incur as a result of this growth. This development, on the other hand, due to Its proximity to the city, relies upon Iowa City for some of the services a municipality offers its own residents, Including access to parks and other recreational facilities. Iowa City residents contribute toward the operation of the County government. In fact, except for tax revenue collected from County residents to pay for a portion of the cost of accessing the Iowa City Public Library and Landfill, and for maintenance of the County's secondary road system, Iowa City and Johnson County residents pay the same tax levy for services provided by the County. Although the County contributes toward the library's budget, the County's contribution, on a per capita basis, Is significantly less than the per capita support provided by the City. Except for taxes paid to the County to access the municipal library and landfill, County residents may utilize all other municipal facilities and services without paying the taxes necessary to support these services and facilities. All in all, City residents subsidize County residents' opportunity to utilize municipal resources. Until this inequity is resolved, there will continue to be financial factors encouraging residential development outside the corporate limits but within close proximity to the city and the city will continue to experience pressures to permit residential development within its urban fringe. 27 /of/ Conclusion The Fringe Area Policy Agreement is Intended to provide for orderly and efficient development patterns. While agricultural uses are preferred In the fringe area, certain areas are encouraged todevelop for residential purposes. Parts of the urban fringe In proximity to existing commercial and Industrial development are expected to develop for these uses and incorporated, at some time, Into Iowa City. It Is to the City's benefit to establish specific policies for the urban fringe which expressly limit non-agricultural development to certain areas within the fringe. That way, the needs of future concentrated residential, commercial and Industrial development In the fringe area can be anticipated and provided at the least cost to taxpayers at large and the financial Inequities experienced by the City as a result of extraterritorial development can be minimized. The Fringe Area Policy Agreement between Johnson County and Iowa City, adopted on December 22, 1983 and amended by the City and the County through November 19, 1987, Is made a this Comprehensive part of Plan Update and Is amended by the City In accordance with the policies adopted In this Plan Update for Fringe Areas 5 and 6. -J I JI 28 L...... .... f F ___ __ /e I, I ECONOMIC DEVELOPMENT The 1978 Comprehensive Plan lists three economic development policies: Encourage commercial activity to take place in existing core areas or neighborhood • commercial centers and discourage the proliferation of new major commercial areas. • Expand the non-residential tax base in Iowa City by seeking new industries and other I7 major employers. • Where possible, locate commercial and industrial activities in such a way that energy resources are conserved. i.� The 1983 Update added to or expanded these policies as follows: I "1 j Iowa City should pursue the attraction of industries within the context of the specific characteristics of the Iowa City labor force. +I Iowa City should pursue the attraction of industries that are compatible with existing industries within Iowa City and which have growth potential. However, constraints in the forms of the ability to provide services and an adequate amount of land must be resolved, 7 J These statements provide the skeleton for the policies and objectives presented in this section. As "economic developmenrl has become more and more an activity of state and local governments, the incorporation of specific economic development goals into planning documents and processes has likewise expanded. Since the 1983 Comprehensive Plan Update, the City has pursued the policies stated above. Changes have been Incremental and major shifts have not occurred in the municipality. According to a recent analysis done by the City's Department of Housing and Inspection Services of building permits Issued from 1981 to 1968, 115 acres have been developed for commercial and industrial use. Of those acres, 54 developed for commercial and office use and 61 acres were put Into Industrial usage. Commercial/Retail Development The location of new commercial establishments, including offices, has occurred primarily within existing commercial areas In the U.S. Highway 6, Riverside Drive, and Gilbert Street areas. New commercial/commercial office areas have begun developing on Mormon Trek Boulevard near Highway 1 and in the Northgate Corporate Park, north of 1.80. 29 According to the Iowa State University Extension Service, total retail sales in Iowa City from 1984-1987 have Increased in constant dollars by a factor of 10%, Land available for additional growth should be assessed to respond to assertions from the development community that insuincient commercially zoned land exists. The location of commercial uses near existing commercial cores should be encouraged. The existing commercial cores, as identified in the 1978 Plan, are downtown, the Lower Muscatine/First Avenue shopping area, the U.S. 6/Keokuk Street commercial area, and the U.S. 6, Riverside Drive and Highway 1 intersection. 1 Industrial Development The City has encouraged light Industry, emphasizing high technology and University -related industries, to locate in Iowa City to expand its non-residential tax base. The City has worked with start-up firms in the University's Technology Innovation Center and has also worked with existing industry to facilitate expansions, Most of the industrial growth in the past eight years within Iowa City has been in the Business Development Inc. (BDI) Industrial Park and along Commercial Drive in Streb's Industrial Park in south Iowa City. Approximately 50% of this growth, in terms of acres consumed, has been in warehousing and distribution activity. The City Assessor's records show that in 1987 Iowa City's primary source of property tax revenue was from residential properties (55.1%) with commercial and industrial property i contributing 36.8% and 7.1%, respectively. In 1984, residential property contributed 55,9%, commercial property 35.9% and Industrial property 6.8% to the taxable property values in Iowa City (after correcting for the elimination of personal property taxes in 1986). j Employment and Labor Force Iowa City is noted for having a highly productive and well educated labor force. Total employment in the Iowa City Standard Metropolitan Area (SMA) which Includes all of Johnson County has Increased approximately 2.6% per year from 1981 through 1987. Since 1984 -� government sector employment has Increased by 540 jobs, retail/wholesale employment has Increased by 1020 jobs, service/construction has increased by 2700 jobs, finance/insurance/real estate has Increased by 510 jobs, while manufacturing and transportation/utilities have shown — smaller gains. Trends indicate that public employment, particularly at the University of Iowa, will remain fairly stable or decline in response to anticipated decreases in enrollment. Losses In government employment between 1985 and 1987 have so far been offset by expansion in the private sector, primarily service and construction. In 1988 the Iowa City SMA's average annual labor force was estimated to be 62,000, In terms — of available labor force, in FY88 there were 12,200 job applicants: 52% male and 48% female; 66.6% between the ages of 22 and 39, 14.2% over 39; 52% with over 12 years of education, 35,7% with 12 years of education, Unemployment in the Iowa City SMA Is consistently low, averaging 2.0% in 1987. Iowa City usually has one of the lowest unemployment rates in the state and often one of the lowest — rates for metropolitan areas in the U.S. The low unemployment rate is consistent with the 30 highly educated and skilled workforce — if employment is not available locally, these people can and do compete successfully for jobs elsewhere. (Labor data source: Iowa Department of Employment Services.) An undocumented but often mentioned issue is "underemployment," i.e. when the workforce is over -educated and by inference, over -skilled for the work available. According to data from the local Jobs Service office, during the year ending March 31, 1988, the largest category of jobs available was services but the highest number of job applicants for each job opening was for the professional/technical/managerial category. Also, a 1986 survey completed by the Iowa City Chamber of Commerce of Johnson County households showed that about half of the approximately 9500 individuals responding, or 4,474, said they were interested in employment in new or expanding industry. Thus, the employment issues facing Iowa City are not the traditional concerns of unemployment and/or an unskilled labor force but of providing the number and type of employment opportunities to utilize the available skills. Economic Development Policies Iowa City should attempt to diversify and Increase the property tax base by (1) encouraging the retention and expansion of existing Industry and (2) attracting industries that have growth potential and are compatible with existing businesses and industries. While dependence on tax revenues from residential property in Iowa City is not unduly high as compared to other cities of similar or larger size in Iowa, expansion of the industrial and commercial property tax base should decrease the tax burden on residential properties. Expansion of the local economy to Include diverse Industries will also provide protection against downturns in any given sector of the economy. The City should concentrate Its efforts on recruiting new firms that complement existing Industries and that can take advantage of technology transfer opportunities with the University of Iowa. The City should also focus on industries that would not harm the environmental quality in the area and would contribute to the overall standard of living. Iowa City should work to Increase employment opportunities consistent with the available labor force. One purpose for encouraging the expansion and attraction of industry is to provide jobs that are compatible with the highly educated labor force and that require a range of employment skills. Industries which require highly technical skills could also employ University graduates who would like to remain in Iowa City but are unable to find jobs commensurate with their expertise. Consistent with this policy, the City should target firms which will Increase Industrial/research employment rather than focus on commercial establishments which increase retail/service positions. 31 ZioV Iowa City should continue and enhance downtown revitalization. As part of the policy of encouraging commercial activity to take place in existing core areas, the City should assess the market for additional high density commercial development, especially that which would be appropriate for the Central Business District area. As the City's iUrban Renewal Program is nearing an end, thought should be given to next steps to allow and enhance commercial and service development in the core area. This includes consideration _ not only of the market for such development, but also of the areas available for infill development, redevelopment and more intense usage. As part of the legacy of the Urban Renewal Program, the City should continue to be concerned with the spatial arrangement and design of downtown development to minimize conflicts between pedestrians and vehicles and to add to the aesthetic environment already created. The City should ensure provision of pedestrian and streetscape amenities and should iencourage a mix of uses to provide both daytime and nighttime activities. Iowa City should provide and protect areas suitable for future industrial and commercial development. The City should determine what areas are suitable for future expansion of the non-residential isectors of the economy in a manner that would protect and be compatible with existing development. Care should be taken to ensure that a proper balance is maintained in the amount of land that is designated for commercial and Industrial use to avoid the blight of unused property. The City should identify (and annex, if necessary) areas suitable for industrial and research/office development. Areas which should be assessed are those contiguous with existing industrial development to the south and east and with existing research/office development or zoning to the north, west and east. Iowa City should provide for the extension of Infrastructure which will induce development In areas designated for Industrial and commercial growth. Progress on the City's new and upgraded wastewater treatment plants Is a major step in providing services necessary to accommodate industrial growth. Extensions of water and - sewer services should be Included in the Capital Improvements Plan as necessary to serve areas designated for growth. The City should also continue to provide transportation corridors to serve existing and future industrial/research areas. The two recent RISE projects (Scott Boulevard/Local Road and Highway t North) are good examples of such planning. Generally the City's role should be directed toward construction of Improvements for which it Is customarily responsible and which provide an area -wide benefit. Stili, the City can influence development locational decisions by providing essential capital improvements to direct market demand and accommodate It in a specific location. This may mean paving a major street, extending utllitles, or removing obstacles such as a lack of parking. Iowa City should continue to cooperate with existing local and regional organizations to promote economic development within Iowa City. With the relatively recent Increase in the importance and level of activity associated with economic development, there are now a number of organizations and groups with responsibilities in this area. The City should cooperate with these groups and use their 77 strengths in encouraging local development, both to be more effective and to augment limited resources. The City should work particularly with the Iowa City Area Development Group, Inc. ([CAD), in I I promoting and recruiting of new industries and, with the Iowa City Chamber of Commerce, in j assisting existing businesses and industries. in addition, the City should cooperate with the Cedar Rapids/Iowa City Corridor group and the Region 10 Satellite Center at larkwood j (( Community College. Iowa City should work with the University of Iowa to enhance and establish avenues for y technology transfer and to develop mutually beneficial programs for encouraging economic development. With the University of Iowa as the dominant employer in the region and one major factor in attracting economic development of the type compatible with the City's labor force, the City and the University must communicate and coordinate their actions to place both entities in a competitive position relative to other university/city economic development efforts. Not only is the University a likely source of new business and Industry from spin-offs of faculty and staff research, other firms find proximity to the University attractive for sharing expertise and technology and for educational opportunities for employees. Construction of the new Laser Facility at the University provides even more Impetus for technology -related economic development in the local area. _I Steps that would aid the City and University in coordination and cooperation Include identification of mutual concerns and types of assistance that can be offered by each party. 7 Establishment of a joint City/University committee should be a priority to realize the economic development goals of the community. Iowa City should consider financial incentives and programs to facilitate achieving the above objecOv". Iowa City is encouraging economic development to improve the standard of living of Its residents (diversify the tax base, better utilize labor force skills) while controlling the negative aspects of such growth (Incompatible land uses, decline in environmental quality). Any Incentive to facilitate economic development should consider these purposes and should be carefully chosen to promote the desired effect. 33 I y M Care must also be taken not to place existing businesses at a disadvantage in competing with new businesses. In general, preferred incentives are those which benefit the entire area (like capital improvements). Also, Incentives should be available to both existing and new businesses and should be administered uniformly. Economic development Incentives can be offered through private organizations, joint public/private ventures, and public agencies and governments. In Iowa, as in virtually all states, there are a variety of Incentive programs. In addition, more and more individual communities offer incentives to complement and leverage state and federal programs. Indeed, Iowa's economic development programs require local participation in the Incentive package. In Iowa City, appropriate Incentives could be designed through public/private partnerships or solely by the City and might Involve establishing a revolving loan fund, land banking or even constructing a building for speculation. Each of these examples Involve repayment or reimbursement by the benefitted party. 34 ENVIRONMENTAL POLICIES The features which make Iowa City such an attractive place to live and work have been identified and it has been determined that the following elements are of importance when — considering what features of Iowa City should be protected and preserved: I -- 1. Iowa City is a very special city combining many of the benefits of small town living with the cultural and recreational opportunities of a large cosmopolitan area. 2. A number of elements both natural and constructed, contribute to the atmosphere of I this community, and it is important to protect and preserve these elements. 3. These elements include not only natural features but also neighborhoods, scenic vistas, entranceways to Iowa City, public areas and buildings. { rI i47 4. These elements and the interaction between these elements provide a sense of j community and integrity to the City and contribute to the general aesthetic and visual impression projected by the City. 5. The economic and social welfare of Iowa City is sustained and enhanced by the sense �. of community and aesthetic values provided by the natural and constructed environment. Since the City Council Is vested with certain powers to foster the healthy, safety and general r welfare of the public, and to protect public Interests, the policies listed below are adopted to maintain and enhance the quality of life in the Iowa City community and to protect the public Interest as it is affected by the elements described below. Envlronmenfalty Sensitive Areas Environmentally sensitive areas are geographical areas containing natural, ecologic, archaeological or aesthetic resources or features which are of value to the public and the destruction of which might result in the permanent or long-term loss of Important public resources (such as mature woodlands), In economic loss, In hazards such as landslides or — flooding, and in the long-term degradation of the environment, Examples of such environmentally sensitive areas Include, but are not limited to, uncommon or unique geologic formations, natural stream corridors including floodplalns, floodways and greenbelts of the Iowa — River and associated creeks, natural stormwater detention areas, bottom land and upland ._ woods, steep slopes, areas of high passive recreational value for bird watching and observation of flowers and other plants and animals and areas containing a high concentration of ecologic — and aesthetic features, i 35 Environmentally sensitive areas may also be those Identified as hazardous sites by an appropriate State or Federal agency. These sites may require special consideration and restriction in their development in order to protect the public health, safety and welfare. _ Iowa City was originally chosen as the seat for the State Capitol because of the natural beauty of the area with Its steep wooded slopes and river bluffs. The exposed limestone bluffs along the Iowa River are geologic formations which are rare in Iowa City, and which also provide _ interesting vegetation and wildlife habitat. Their destruction would result not only in the loss of this unusual landscape feature, but would also accelerate the erosion of the steep wooded slopes in the area, with possible resultant landslides and siltation. The Iowa City area was once heavily wooded, particularly along the river and creek beds. Few wooded areas now remain to provide diversity and other benefits. Northern Iowa City is one area where steep wooded slopes and ravines remain relatively untouched. Intensive development of such slopes destroys not only vegetation and wildlife habitats, but frequently • results in erosion, mudslides, the filling in of ravines, and severe changes in drainage patterns. A crucial factor in the stabilization of steep slopes is the development of a stable drainage system. Degree of slope, soil type, vegetative cover, underlying geology and precipitation patterns determine the run-off patterns. Approximately 35.40% of precipitation is not retained by the soil or used by plants, and will run off steep, wooded slopes. As the vegetative cover is disturbed by development, new drainage patterns develop which may result in the erosion of neighboring private and public property and cause downstream siltation affecting water quality. As a result costs may be Incurred by private property owners and by the City to correct the problems created. Woodlands themselves are Important moderators of climactic phenomena such as high winds — and flooding, and help to protect watersheds from siltation and erosion due to heavy runoff or wind. The woodland floor acts as a filter to water percolating into groundwater reservoirs or rivers. The woods also improve air quality by absorbing some air pollutants, and serve as — noise buffers between residences and heavy noise generators such as Interstate highways. Finally, woodlands in an urban environment provide recreational opportunities, and visual relief from the built landscape, adding to the quality of life and therefore the general welfare of any community. Rivers and creeks are the natural drainage channels of any area. As development Increases and the Impervious surface area Increases, more and more surface water runs off directly Into the creeks and rivers. The floodway, and floodplain of streams are the natural corridors for this water and should be maintained for its flow. If, in addition, vegetation is maintained along the river and creekbanks, more water can be absorbed and the risk of flooding Is reduced. Also, the filtering affect of the floodplain soils will reduce the amount of sediment and chemicals ` entering the creeks and rivers and help to maintain water quality and to reduce the risks of flooding and erosion. If greenbelts are maintained along rivers and creeks they provide diversity of habitat and by their linear nature extensively affect adjacent development. Protection of the Iowa River and Ralston and Willow Creek floodplains will reduce the need for further extensive modifications of their channels in order to reduce flooding. /09/ I policy: It Ia the policy of the City of Iowa City to preserve and protect environmentally sensitive areas as Identified by the City, and to develop measures to protect the public from those sites Identified as environmental hazards by appropriate State or Federal agencies. Buffer Areas and Open Space Buffers between land uses, such as commercial and residential, serve to screen one use from another, and help to decrease the adverse affects - such as noise, traffic, air pollution - of one use upon another. Buffers may also help to provide a transition between land uses. Buffers may be vegetative, such as a greenbelt of trees between an Interstate highway and residential development; a solid fence screening a commercial use from a neighboring residential area; or a structure designed in such a way that the structure itself is oriented to act as a buffer to the adjacent land use. Transitional buffers provide an attractive transition between land uses such as those seen on Rocky Shore Drive with the gradation from river, to plantings along the sidewalktbicycle trail, to single-family residential development. Buffers provide diversity within the City, and, if vegetative in nature, have many of the beneficial effects of woodlands but on a smaller scale. Open space provides relief from urban development and opportunities for recreation. Open space may be unimproved natural areas, pocket parks, playgrounds, neighborhood or city- wide parks, stormwater detention facilities, stream corridors or greenbelts. All these provide relief from continuous, contiguous development and the intensified extremes of temperature, Increased air and noise pollution and the psychological stress associated with such development. As the City grows and develops, noise, water and air pollution Increase and areas of open space and vegetation which help to alleviate these pollution problems decrease In size and number. protection of existing open space is therefore vital in preventing the degradation of the Iowa City environment, policy: It is the policy of the City of Iowa City to preserve and promote the creation of buffer areas and open space as Identified by the City. Neighborhoods and Structures Neighborhoods provide familiar surroundings - buildings, places to walk, people - a sense of security and community stability. Neighborhoods may be private - a place where groups of individuals live; or they may be public - places where many people gather to enjoy the surroundings or to Interact, it Is within Iowa City's "private" neighborhoods that people find the benefits of small town living and in the "public" neighborhoods that one can enjoy the diversity often found in a larger city. There are within Iowa City historic neighborhoods and structures which provide roots for the residents of the neighborhood and perpetuate a legacy of historic, architectural and cultural achievement for all of Iowa City. Some of Iowa City's neighborhoods and structures, though I I 37 I — /09/ i not historic, provide an identity for their residents which adds to the residents' sense of well- being. Likewise, there are public places within Iowa City which have become unique gathering places for the people and add to the entire city's sense of community. Policv: It is the policy of the City of Iowa City to preserve and protect the unique l attributes of Iowa City's public and private neighborhoods, as Identified by the City, for the general welfare of the community at large. -I Entranceways to Iowa City LlEntranceways to Iowa City are all the major thoroughfares along which people approach our city. These entranceways often provide the first Impression one has of the City, informing the visitor and resident alike of the aesthetic values of the community. The visual impression projected of the City through its entranceways can contribute to the economic and social welfare of Iowa City by making it a more attractive place to live and work. Policv: It is the policy of the City of Iowa City to preserve and enhance the entranceways to Iowa City. Scenic Matas There are elements of Iowa City, both natural and constructed, which are unique to the city �l and are open to public view. People are reminded through these scenic vistas of the heritage J of the community and the natural beauty of the land, Policv: It Is the policy of the City of Iowa City to seek to ensure that certain unique features within Iowa City remain perpetually accessible to public view. I 38 I _ I HOUSING The housing goal of the City of Iowa City is to meet the varied housing needs of its citizens and to ensure, to the extent possible, safe, healthy and affordable housing in a pleasant !I environment. The involvement of City government in housing usually takes two forms: through the City's regulatory powers and through programs which help people acquire or maintain I housing. The housing Issues which are presented below may be addressed through the City's ability to zone land making housing opportunities more or less varied; through building, housing, and subdivision standards affecting the cost of housing; through federal, state or local funding of housing assistance, rehabilitation programs, or housing for special populations; and through private/public partnerships to assist first-time homebuyers and foster the provision of w adequate and affordable housing. i.! In the 1983 Comprehensive Plan Update, a number of policies from the 1978 Plan were carried iforward. Three policy statements addressing the location of housing and housing for specific groups were added based on a Housing Market Analysis completed in 1982. The Community Development Plan, 1987-89, adopted by the City Council as a requirement for receipt of Community Development Block Grant monies, and the Housing Assistance Plan expands upon these policies. This Update will pull together the principles of the previous housing policy statements to guide future City actions. Housing Conditions The 1980 Census, which is the most recent data on housing units available, counted 19,232 year-round housing units in Iowa City. Between January, 1981 and April, 1986, 805 permits were Issued for construction of new residential structures which Included 511 single-family dwellings, 121 duplexes and 1,920 multi -family units for a total of 2,673 new housing units. Increasing demands for residential living units created by Increased enrollment at the University of Iowa have caused a continually expanding housing market. In 1982, the Iowa City Rental Housing Survey showed that the vacancy rate for rental housing was about 1.6%. The 1986 Rental Housing Survey showed a higher rate of 5,7%. The results of the 1986 Rental Housing Survey reflect the effect of the surge of apartment construction between 1982 and 1984 on rental rates. However, a continued relatively low vacancy rate indicates room in the market for additional mufti -family units. An exterior housing survey completed in 1988 through a windshield survey of a limited number of structures found that 63% of the 274 units observed had apparent major deficiencies which were suitable for rehabilitation; none were dilapidated; and approximately 37% had minor or no deficiencies and were basically In sound condition. Most deteriorated housing is scattered throughout the City's older neighborhoods. These neighborhoods, located close to the central business district and the University of Iowa, are desirable locations for University students. A strong demand for housing in these neighborhoods has caused periodic overcrowding of rental units, the conversion of single - 39 /09/ I " family homes to rental units, and the construction of apartment buildings next to single-family structures. These pressures have caused some deterioration of the housing stock. However, these negative influences have been offset to some extent by the City's housing code enforcement program, by down zoning in some older neighborhoods, by the appeal of historic structures in older neighborhoods for single-family use, and by the provision of newly constructed apartment complexes within walking distance of the University. Housing Needs The presence of the University of Iowa and the large hospital complexes has for years created demands for housing in Iowa City. This demand often negatively affects the elderly, new households and families, many of whom are competing with students for the same housing close to campus, downtown and near the main centers of employment. Although the Iowa City building boom between 1982 and 1984 has alleviated some housing problems, many of the new units are too expensive or poorly located for lower Income persons. The Comprehensive Plans of 1961, 1978 and 1993 targeted development of high density housing near the University and the retail/employment area of downtown as a goal. +1 Consequently, areas immediately north and south of downtown have been zoned for high- density multi -family use. Amendments to the high-density zone regulations have been made in recent years to encourage even higher density development. This type of development close to the center of the City should continue to be encouraged to provide housing opportunities for those people who wish to live close to the University and downtown and to reduce the demand for the conversion of lower density neighborhoods, farther from the center of the city, to high-density housing. 1. Housing for New Households and Families. There is the need to provide housing opportunities for low Income persons, especially families and new households. The need is for low-cost rental and owner -occupied housing, and assistance in obtaining such housing in locations which are accessible to schools, Jobs, shopping areas and on or near transit lines. One important administrative action a city can take to enable the construction of lower- cost owner -occupied housing is to zone sufficient land for housing, and particularly for less expensive housing like mobile homes, duplexes, townhouses, and condominiums and detached single-family housing on small lots, In some Instances, even if the proper _i zoning Is in place, the cost of Infrastructure diminishes the possibility of constructing affordable housing. The City may, to foster the construction of affordable housing, enter Into public/private partnerships to lessen the burden on the private sector of Infrastructure costs. Having sufficient land zoned and ready for development helps to hold down the price of land, opens up development opportunities for land holders and developers, and expedites the land development process. Another action a city can _j take Is to re-evaluate their housing, building and Infrastructure construction standards to continue to achieve quality housing and subdivision but at a lower cost. 2. Housing for Special Populations. There is a growing need for housing opportunities for special populations. Shortages in suitable housing have been Identified for people who 1) have long-term mental disabilities, 2) require physically accessible, barrier -free residences, and 3) are elderly. In particular: Iowa City has many people who would benefit from a boarding-house atmosphere providing companionship and a degree of security (i.e., shared meals and a — communal living room), but who would not need personal care or formal supervision. f ,_I A boarding-house setting could also provide housing opportunities for substance i abusers who are recovering. There is a need for affordable housing which can conveniently accommodate people who use wheelchairs, but who require minimal or no supervision. Although • handicapped accessible housing exists and some units are required to be handicapped accessible in new apartment buildings, a shortage of such housing to met the needs of a variety of people with physical disabilities does exist. ! The 1980 Census figures show 11.4% of Iowa City's population is 55 and over, I{ whereas nationally, 20.9% of the population falls Into this age group. The predominance of younger people connected with the University probably accounts for this disparity. With increases in services to the elderly in Iowa City since 1980 and with the national "greying" of the population, the percentage of Iowa City's I population which is now 55 or over has probably Increased. Despite the seeming minority position of the elderly, the elderly have unique housing needs which should be met. Considerable progress has been made in meeting these needs in the last few years. However, there continues to be demand for low-cost housing for the elderly on fixed Incomes which will permit them to live independently — for as long as possible. Some of the elderly have a desire to live with other persons of the same age, others prefer to be among mixed age groups. Many elderly need help with minor chore services and housing, counseling and assistance with financing their housing. Much has been done by the City and the County to support shared housing programs and elderly services so people can remain in their own homes longer. The City has made available the option of accessory apartments In single-family neighborhoods to permit the elderly to obtain the financial ability to retain their homes. More can be done to provide smaller, more manageable units as a housing alternative for the elderly and, thereby, release some of the older, larger housing for other households, _ 3. Rehabilitation. As the cost of new housing continues to rise, the viability of existing housing stock becomes critical as a resource for housing accessible to many segments of the population. Continuing housing needs are the upgrading and maintenance of housing stock. In some cases, lower Income homeowners as well as elderly and disabled persons need assistance in maintaining their homes. In rehabilitating and — maintaining older homes, consideration must also be given to preservation of historic i structures and energy conservation measures which will reduce heating and cooling costs. 41 — 4. Housing on Large Lots. One of the specific policies of the 1978 Plan was to "consider the diverse needs of renters and homeowners in making residential development decisions." This statement guides the City toward actions which encourage varied — housing opportunities so that people can make choices about their living environment. " One component of Iowa City's housing market is those people who desire and are able to pay for housing on large lots. In recent years, the greater Iowa City area has seen j a demand for property on which to build large, expensive homes. Much of this demand has been met through development in unincorporated parts of Johnson County. For r three reasons it is in the community's interest to attempt to accommodate this development within Iowa City: I -i 1) Extended development beyond the corporate limits and away from employment and service centers is inefficient in terms of the provision of public services such as fire protection, police protection, and transportation to schools. This type of development Is also Inefficient in energy consumption and travel time. The 1978 + Plan advocated designating areas for large lot development in Iowa City to encourage residents to locate in the City as an energy saving measure. j 2) Residents of the County use the Infrastructure and services of Iowa City without J necessarily contributing a fair share of the cost. This is particularly true in Instances In which the University, which pays no taxes to the City, is the entity attracting county residents to the urban services. 3) Although, generally speaking, residential development does not generate sufficient 7 tax revenue to cover the cost of all services to it, including schools, the housing built on large lots is usually higher cost housing which enhances the tax base and is a positive factor in the tax revenue/service cost equation. In an effort to provide additional housing opportunities in Iowa City and to address the issues of efficiency in development and equity of service provision, the designation of land for large lot development and re-evaluation of the Improvements required for such development should be undertaken. HOUSING POLICIES i _.. To carry out the goal of Iowa City to provide a variety of housing opportunities and to provide safe, healthy, affordable housing in a pleasant environment, the following statements will be used to guide housing decisions In the future: • The City has a responsibility to consider the diverse needs of renters and homeowners in making residential development decisions. • Incentives, such as density bonuses In planned developments, may be provided to produce — a mix of housing types. 42 i • Incentives, such as density bonuses in planned developments and public participation in infrastructure Improvements, may be provided to produce more affordable housing. • High-density housing and mixed use developments are appropriate close to the Central Business District. Rehabilitation and reinvestment in existing neighborhoods should be encouraged to maintain existing housing stock and preserve desirable neighborhood characteristics, particularly in older neighborhoods. Older neighborhoods provide a considerable portion of the City's affordable housing stock and should be preserved for that, among other reasons. • The creation of desirable living environments should be encouraged with the provision of open space and proper site design through a new planned development process. • The housing needs of low -moderate income households and special populations such as people with disabilities and the elderly should be accommodated. 43 /09/ III -I • Incentives, such as density bonuses in planned developments and public participation in infrastructure Improvements, may be provided to produce more affordable housing. • High-density housing and mixed use developments are appropriate close to the Central Business District.

Beyond a recognition of the needs and services necessary for the general population, this Plan acknowledges the need to address the requirements of special populations - the frail elderly, families in stress, the handicapped, the mentally ill, Juveniles, and others in need of special hI programs. These needs can be met through various human service programs. Those programs, however, require the existence of certain facilities, depending upon the population r, served. it is the intent of the City that provisions be made within the Zoning Ordinance, which will Implement this plan, to allow for the appropriate placement of the requisite facilities to better meet the needs of Iowa City's special populations. 44 I i NEIGHBORHOOD COMMERCIAL CENTERS Residential neighborhoods are basic units of a city. Socially, neighborhoods are strong forces In the development of individual and family life. Neighborhoods provide a network of Interactions which reinforce a resident's sense of identity and belonging. Physically, a residential neighborhood is an assemblage of dwellings within a physically integrated area that generally contains certain common facilities that are conveniently accessible to its residents. A neighborhood usually includes sufficient population to support the services required within the neighborhood, thereby making the provision of infrastructure and other municipal services and facilities cost-effective. This section of the Comprehensive Plan Update describes the physical characteristics of residential neighborhoods and focuses on one particular element of a neighborhood - the neighborhood commercial center. Neighborhood Characteristics Boundaries. A residential neighborhood provides easy access to the basic facilities and services required by the average household for its comfort and convenience. Residential neighborhoods are typically cohesive units that are unimpaired by physical barriers that inhibit interaction among the residents. Neighborhood boundaries are generally set either by natural features such as topography, stream valleys, or terrain; by major streets and trafficways; or by developed features such as railroads, power lines, recreational and other open space uses or community facilities. These features usually act as barriers to neighborhood cohesiveness and, therefore, serve to delimit one neighborhood from another. Circulation. Street patterns within a residential neighborhood are designed to discourage through -traffic which is disruptive to a neighborhood. Instead, while good access to main traffic arteries is essential, the neighborhood street network is designed to encourage low volume, local traffic, This design consideration preserves the residential atmosphere of the neighborhood and provides a safer environment for the pedestrian oriented activities characteristic of a residential area. Size. For planning purposes, the extent of the neighborhood has often been determined by the service area of an elementary school. The neighborhood school concept is based on the premises that 1) elementary schools should be located so that most of the students live within walking distance of the school, and 2) the school facilities - open space, gymnasium, or classroom - should be available for use by residents in the neighborhood surrounding the school grounds. Neighborhood schools enhance the neighborhood's sense of Identity but also identity a population that is collectively capable of supporting most of the services required within the neighborhood. 45 Shifts in population within a community do not always permit implementation of the — neighborhood school concept, but this concept generally identifies a population that can support the other services required in a residential neighborhood. Organizing development in a manner consistent with the neighborhood concept is cost-effective from the standpoint of _ providing the facilities and services expected by residents of a residential area. Besides convenient access to a city's infrastructure and its elementary schools, neighborhood residents also expect to be within close proximity to recreational areas and to a local convenience shopping facility to meet the needs of day -today living. While the usual residen- tial neighborhood will not contain certain facilities regularly needed by Its residents such as centers of employment, high schools, major shopping centers, specialized health services and i similar facilities which ordinarily reach a city-wide clientele, convenient access to elementary 1 schools, public open space and small shopping areas enhances the livability of residential neighborhoods. The following discussion focuses on the characteristics of a neighborhood commercial center. l Neighborhood Commercial Centers Purpose, Scale, Location. The concept of residential neighborhoods is reinforced when accessible services which reduce time, energy, and transportation costs are available to local residents. The small neighborhood shopping center should be considered a local convenience =1 and service facility focused on supplying the everyday needs of a limited residential population within a relatively small trade area surrounding the shopping center. Convenience shopping facilities have a neighborhood orientation and supply necessities or services usually requiring frequent purchase with a minimum of consumer travel. Therefore, occupants of a neighborhood commercial center are generally those businesses catering to the sale of convenience goods such as food and drugs and the provision of personal services for a fully developed residential neighborhood. A grocery store or grocery store/drugstore icombination is favored as the principal tenant in a neighborhood commercial or convenience _ center. Convenient access to the commodities available at this establishment is Important In enhancing day -today life within a neighborhood. While other retail and service establishments may wish to locate in neighborhood facilities, these tenants are typically subordinate to the grocery store and/or drugstore in size, although they may be served by the same population (approximately 8,000 people). „ Tenants of a neighborhood commercial center should be capable of being economically supported by nearby population. Businesses reliant upon community -wide patronage are not suitable tenants In a neighborhood commercial area and should be located in designated J community commercial areas. The neighborhood shopping center should contain only the types and number of stores or offices which can be well -supported by the population of the Immediate neighborhoods. A conventional grocery store (total area of about 25,000 square feet), a drugstore, and other tenants of a neighborhood shopping center should be largely dependent upon the relatively small trade area surrounding the shopping center. That way, the residential purpose and character of the neighborhood is preserved. The key characteristics distinguishing establishments permitted in a neighborhood commercial _ center from those uses allowed in other commercial areas is that the products and services available within neighborhood commercial centers are limited to those commodities and services essential for day -today living and the extent of the service areas of neighborhood commercial uses is narrower. Provided medical clinics or other office uses can rely on a trade area no greater than the trade area of conventional grocery stores (approximately 8,000 people), these uses may be considered appropriate uses within a neighborhood convenience _ center and compatible with the scale of a neighborhood commercial center and with the other { occupants of this type of facility. Convenient access to medical services, for Instance, is a I -I feature residents of a neighborhood may find comforting and appealing. Neighborhood shopping centers are, on the average, about one to two miles from other commercial centers and, depending upon the density of development, rely upon the trade area within a one-half to one mile radius from its location. The small neighborhood shopping center Is normally located on the periphery of a residential neighborhood with frontage on arterial streets - preferably at or near the Intersections of major thoroughfares. This location makes the center easily accessible to its trade area by both pedestrian and vehicular traffic and diminishes the negative effects of commercial enterprises in close proximity to the center of IM residential development. Because a neighborhood commercial center generally straddles the boundary of a residential .! neighborhood, its service area may not coincide with the service area of a neighborhood's elementary school. An elementary school may be effectively located in the center of a j r residential area without disrupting the neighborhood. its service area, therefore, will usually be �i the residences surrounding the school and within walking distance of this facility. A neighborhood commercial center's location on a major thoroughfare or at the Intersection of two major streets Implies that it is probably on the boundary of two or more residential areas. Therefore, a neighborhood commercial center usually relies upon the residents of more than j one neighborhood. Site Location Criteria. As new residential development occurs, new market areas are created and the viability of additional commercial centers is Increased. To guide land use decisions in developing areas in Iowa City, site location criteria for neighborhood commercial centers have been established. The following criteria are to be used In considering locations for new commercial centers in developing residential areas: a. Location Vehicular access, as well as walking distance, should be considered for the location of a neighborhood commercial center. Where a neighborhood commercial center is ! - justified, it should be located on a major thoroughfare and should minimize traffic movements extraneous to the normal traffic flow within the neighborhood. i 47 I b. Size There must be suircient site area for the development with room for expansion, for buffer strips separating commercial and residential uses, and for stormwater management where needed. A site size range of 3 to 7 acres is appropriate to ensure that the center retains a scale compatible with its surrounding neighborhood and has sufficient space for a well-developed site. C. Shape The site should be compact and on one tract of land. A site divided by a traHicway Interrupts continuity for shopping, Impedes the flow of pedestrians, complicates car movements, and contradicts the basic principle of unity for the shopping facility. Frontage requirements which encourage corner lot development and effectively separate residences from the commercial center are desirable. Although site depth cannot be specified with any meaning, depths of 400 feet or more should distinguish the center from the standard strip commercial areas which are usually zoned only 100 to 200 feet In depth. d. Access Access should be easy and convenient. Adequate access should accommodate the traffic load, but not create traffic problems. The center should be located on the periphery of the neighborhood so that customer traffic from outside the Immediate neighborhood does not filter through nearby residential streets, creating nuisances and irritations for the local residents. Entrances Into and out of the center must be well separated from major street Intersections (at least 125 feet from the Intersection). e. Local Conditions The site should have adequate utility services available to it, proper zoning, and favorable neighborhood sentiment. f. Topography A site should not require excessive grading. The site should be relatively level with grades not in excess of approximately 2.5 to 3 percent. g. Competition It is Important to consider the location of the center in relation to both existing and potential competition. Well located centers may, on the average, be found at Intervals from one to two miles apart, depending upon the density and economic level of the development to be served. The trade area of each of the tenants of the center should be no greater than the trade area of conventional grocery stores and drugstores (approximately 8,000 people) and preferable less. B." /Df/ NEIGHBORHOOD OPEN SPACE Public neighborhood open space serves the public interest by providing opportunities for active recreation and play as well as a place for relaxation and passive pleasure. It is considered a vital part of a community and often serves as a focal point of neighborhood activity. Open space, like streets, water mains and sewers, is a capital improvement Intended to serve the immediate and future needs of area residents. The process of urban residential growth requires these improvements in order to ensure a safe, healthy and livable environment. As population density increases and private open space decreases, the demand for public open spaces will increase. i" Neighborhood open spaces are small areas intended to serve a local residential population. ii Many times neighborhood open space is found adjacent to elementary school sites and the combination of both are considered a focal point within the neighborhood. The function of neighborhood open spaces is reflective of the type and character of the neighborhood within j ( which it will be developed. Within Inner city environments where the availability of open space is extremely limited, Its use may be passive providing merely a peaceful place in the midst of urban densities. Within a developing single-family residential subdivision, open space can be of sufficient size to serve both active and passive recreation needs. 1 I 7 This Update proposes a methodology to analyze open space needs at the neighborhood level and develop specific implementation strategies for the acquisition of open space to satisfy that need. The concentration of this Update on neighborhood open space Is not intended to preclude or Ignore the need for city-wide parks, such as the Iowa River Corridor trail system. The policies of previous years pertinent to city-wide parks are carried forward, The plan is Intended to be a dynamic working document that will reflect current and projected needs for open space within existing and developing housing environments. Regular review and updating will be essential in order for the plan's policies and standards to remain current. Comprehensive Plan Background The 1978 Comprehensive Plan presented the first comprehensive approach to the allocation of parks and recreation resources throughout Iowa City. Within this process, neighborhood open space was seen as a key resource for which additional planning was required. Certain principles of the 1878 plan which directly or Indirectly affect the allocation of neighborhood open space are still held to be valid and reaffirmed through this plan. They are as follows: 49 /09/ I I Provide adequate community facilities in suitable locations to meet the needs and desires of Iowa City residents. Maximize the efficient use of public facilities through the joint development of such facilities. Objectives: Develop public facilities jointly with other compatible public uses. Provide a complete range of parks, open space and recreation opportunities for the residents of Iowa City, distributed according to population density, suitability of sites, accessibility, and neighborhood needs. Recommendations: Develop written agreements between Iowa City, the Iowa City School Board, the University of Iowa, and Johnson County, which coordinate provision of parks, recreation and open space in an efficient manner, and which ensure that adequate facilities will be available for the entire population. Acquire sites for joint park/school sites. Establish a financial management system to carry out acquisition of parkland and open space through bond Issues or through the minimum open space requirement for neighborhood parks, or by other means. Policies: Purchase or acquire through dedication future sites large enough to accommodate schools, parks, and other public facilities prior to the development of the neighborhoods which they are intended to serve. Require a minimum open space allocation as part of the subdivision process. Locate neighborhood parks within walking distance of all residents living in areas where housing densities are greater than two dwelling units per acre. The 1978 Plan subdivided Iowa City into 13 "Neighborhood Park Service Areas." Within each neighborhood park service area a needs assessment was performed which projected the amount of open space that would be required to serve existing and future populations. The plan, however, was never Implemented through the development of strategies to purchase and/or acquire open space. The 1983 Comprehensive Plan Update recognized that a reevaluation of the 1978 Plan was necessary. The following Issues are targeted for evaluation: 1) The plan needs to address the city as a whole with regard to the allocation of neighborhood open space, The 1978 Plan deleted the downtown and already developed areas from consideration of the neighborhood open space planning process. 50 2) The park service areas of the 1978 Plan, within which open space needs were projected, need to be reevaluated. The 13 park service areas are too expansive and make determination of local neighborhood open space needs more difficult. 3) The 1978 Plan applied a "national standard" for determining neighborhood open space needs. Application of a national standard does not recognize local differences in population characteristics, density, housing form, changing neighborhood characteristics and form, open space availability, economic base, topography, etc., and should not be expected to meet specific local needs. Reevaluation of the applicability of a national standard as it applies to different areas of the city is necessary. 4) The 1978 Plan developed a methodology to project neighborhood open space needs in developing areas, but, an action plan by which specific implementation strategies to purchase and/or acquire the needed open space was never adopted by the City. Within this Update, Iowa City is divided into three Open Space Zones; two represent already developed portions of the City - the Inner -City Zone and the Developed Zone, and one represents the substantially undeveloped portions of the City - the Developing Zone. Each zone is further divided into smaller Open Space Districts within which the need for open space Will be determined. The detailed analysis of the plan focuses on the eleven Open Space districts of the Developing Zone. With the compilation of more specific information regarding land use patterns, occupancy, etc., the needs and appropriate acquisition measures for the other two Open Space Zones will be determined. yDEVELOPING ZONE The Developing Zone, which represents the outer rim of the city, contains areas in which substantial pockets of undeveloped land remain. Based upon the characteristics of properties within this zone and development projections, criteria for the selection of minimally acceptable open space were determined and a process for the calculation of open space need was developed. The greatest percentage of undeveloped land within this zone is projected to be developed at an RS -5 density with a few multiple family districts Identified for development at an RM -12 density. These assumptions were used in the needs assessment calculations for each district within this zone. It is the goal of this portion of the Update to provide a policy for the acquisition of sufficient open space in neighborhoods for active and passive recreational uses. Active recreational facilities may Include basketball goals, small play fields, or playground equipment not Intended for organized sports. Passive recreation may Include picnicking, walking or merely enjoying open space. Implementation of this plan will seek to provide for both active and passive needs within a district. -J, 1. SHe Selection Criteria: The site selection criteria are used to determine minimally acceptable open space within this zone. The criteria listed are guidelines for the .1 acceptance or rejection of dedicated or purchased open space as determined by the needs assessment process: M 51 /of/ I i The size of the parcel should be between 3-7 acres. The acquisition and/or development of contiguous open space parcels within adjacent developments to reach the sum of seven acres shall be encouraged. The parcel should not be accepted if the City must incur considerable time and expense to prepare or maintain the parcel. The parcel should be designed so as to require low maintenance. The parcel should be located centrally, usually within 1/4 to 1/2 mile of most residences within a particular district. Areas of high population density within a district, particularly multi -family dwellings, should be favored when locating open space. The parcel should be easily accessible to potential users in the district and must be safely accessible on foot. Neighborhood open spaces are primarily Intended for pedestrian accessibility although certain circumstances may require provision for limited vehicular parking where pedestrian access is shown to be difficult. The shape, topography and physical characteristics of the parcel must not limit its use as public open space. Unique landscape, such as environmentally or ecologically fragile areas and stormwater detention basins may also serve as acceptable open space. Recognizing the various functions of open space, only a portion of these areas should contribute to the total open space needs of a district. The site shall be free of existing and potential hazards or pollution from a variety of sources, including Industrial uses, railroads and roadways, The site shall be located adjacent to local streets to provide for accessibility and safety and away from major arterials. Schools and existing parks shall be credited in the calculation of open space needs in districts they influence. 2. Needs Assessment. A formula has been devised to determine the amount of open space required for each of the 11 open space districts. This formula relies on several needs assessment standards and assumptions which are outlined below. a. Needs Ratio: A need of three acres of neighborhood open space for every 1 ODO residents is established as a basis for the needs assessment. This ratio is based on a national standard for neighborhood open space which was found to be appropriate for the Developing Zone. 52 b. Density of Development: When projecting the population of undeveloped areas, it was decided that the projection should be based on the assumption that an area will not develop to the maximum density for which it is zoned. Requirements for streets, stormwater detention facilities, irregular topography, and consumer demand for larger lots often prevent areas from developing to maximum density. A survey of past developments in Iowa City shows that, on the average, areas developed to 65% of the maximum allowed density. The formula thus assumes that areas will develop at 65% of maximum density (e.g., If an area is zoned for maximum of five lots per acre (RS -5), it shall be assumed that there will be 3.25 (65% of 5) lots per acre containing households of 2.33 persons each). This factor reflects the historical trend in development in Iowa City; inclusion of this factor in the calculations in no way negates previously adopted policies to encourage the development of Iowa City's residential areas at the density permitted by zoning. C. Credits: The formula gives credit for existing public open space within a district towards fulfilling a district's open space needs. Existing parks are given up to seven acres of credit. This is consistent with the site selection criteria of a neighborhood park being a maximum of seven acres. To give full or more than seven acres of credit to existing large parks might lead to one large park fulfilling a district's entire open space need. The character, function and location of large parks often makes them unaccessible to a great portion of an open space district or unattractive for neighborhood use. Thus, they are unable to serve as neighborhood parks and are given only partial credit for doing so. i Since school shoe often provide open space in the form of playgrounds, sports ' fields and other open areas, they are given partial credit towards fulfilling the districts' needs. However, this credit is limited because the City has little, if any, control over the use of school sites. The formula limits this credit to 25% of the school's open areas, or five acres, whichever is less. This prevents a large school site, such as West High (78.7 acres), from inappropriately filling a district's entire open space need. The standards and assumptions outlined above have been integrated Into a formula which determines the amount of open space required for each of the 11 open space districts. [A x DU x PDU) + CP] x 3/1000 • (SS + PS) = OSD Projected Population x Open Space Standard - Credits = Open Space Need A = Number of acres DU = Dwelling units per acre (65% of maximum density allowed by Zoning Ordinance) PDU = Persons per dwelling unit (2.33 based on 1980 Census) PP = Projected population CP = Current population (from 1980 Census data) 53 /09/ i'� TOSN = Total open space need for district OSD = Open space to be dedicated SS = School site (25% or 5 acres, whichever is less) PS = Park space up to 7 acres The procedure for applying the formula to developing districts is as follows: 1. Determine the Total Projected Population of a District a. land area of each district divided Into two categories: -Previously developed areas, and -Non-developed areas. b. Area measurements are taken to determine: -Gross acreage of a district, -Acreage of previously developed areas, -Non-developed acreage, -Existing park and school acreage. C. Non-developed areas are divided according to zoning density (e.g. RS -5, RS -6, RM -12, etc.) to project population. d. Where possible, census data is used to determine the current population of previously developed areas within a developing district. e. When census data is not available, or ambiguous, or when an area has not yet been developed, it shall be assumed that there will be 2.33 persons per lot as Indicated by the 1960 census. The number of lots shall be assumed to be 65% of the maximum number of lots allowed according to the Zoning Ordinance. I. Total potential population of a district is determined by adding (d) and (e) above. 2. Determine the Gross Acreage of Open Space Required Standard of three acres open space per 1000 residents shall be applied to the total population, (I) above, to determine the total open space need for each district, 54 I 3. Allowance for Credits a. If the district contains Open space In the form of a park or school site, a portion of that open space shall be applied toward fulfilling the district's open space need. No more than seven acres -J of credit shall be given to an existing park. Up to 25% of the school site or five acres, whichever Is less, shall be credited towards fulfilling a district's open space need, A portion of the park or school site which Is credited toward a district's need shall be subtracted from thdistrict's to ta oen sace needs, leaving the amount that muste be obtainedl thrpoughpdevelopment fees or through developer dedication.

In order for this plan to be effective, certain actions need to be taken so that needed open space can be acquired, developed and maintained. It is the recommendation of this plan that needed open space within the Developing Zone be acquired through the subdivision/LSRD approval process by implementing a mandatory open space dedication and/or fee in lieu of dedication ordinance. This appears to be the most equitable method for acquiring needed open space since the amount bears a direct proportion to the level of demand generated by new developments. It is also recommended that Iowa City cooperate with Johnson County to coordinate the allocation, development and maintenance of open space of mutual benefit to adjoining developments within the City and County. Once the analysis of the Inner -City Zone and Developed Zone has been completed, various methods of Implementation will be investigated. Due to the limited availability of open space within these two zones, other methods of acquisition, such as capital improvement programming and fee -simple purchase may be required. In order for this Plan to be effective, it is Incumbent upon the City to allocate sufficient funds so that newly acquired open space can be developed and adequately maintained. An alternative to public funding of maintenance Is development of neighborhood maintenance districts coincident with the open space districts. Under this alternative, benefitting residents are responsible for the maintenance of their neighborhood park. 57 i IJ J �j 'J I Ll Acquisition d Maintenance There is a demonstrated need for neighborhood open space throughout Iowa City.

There are 19 school buildings in the system, 17 of which are located within the Iowa City -University Heights-Coralville area. Fifteen of the 19 structures are elementary schools, two are junior high schools and two are high schools. An alternative d secondary school program, the Community Education Center (CEC) is located in the district's administration building. w -� Enrollment r' lei September, 1988, enrollment figures show a total public school census of 8,918 students, a 9.1 percent increase in enrollment since September, 1983. Although the number of secondary students has decreased from 3,810 students to 3,624 students in this five-year period, the number of elementary students has risen by 932. This represents a 21.4 percent increase between the 1983 elementary school enrollment of 4,362 students and the 1988 enrollment of 5,294 students. Although significant Increases in district population are not anticipated, district administration expects that shifts in population may occur as undeveloped portions of Iowa City and neighboring unincorporated areas and communities become suitable or desirable for development. These demographic changes affect the ability of existing schools to accom- modate students. School Capacities Many factors affect the capacity of a school, including the pupil/teacher ratio, the use of temporary structures, and commitments made to provide specialized programs. Changes in the placement of special programs within the school system will decrease or Increase a given school's capacity accordingly. Based upon a current pupil/teacher ratio and existing space commitments made for regular and special instructional programs, the elementary schools have the capacities listed In the following table. Because conditions do not exist to permit use of all classrooms 100 percent of the time, five days a week, a multiplier of .9 is applied to determine the "effective capacity" of each school. An average class size of 23 students Is assumed. 58 While the district has the overall maximum capacity to accommodate 732 additional elementary - aged school children, the enrollments at several elementary schools (Coralville Central, Horn, Lucas, Penn, Roosevelt, Shimek and Grant Wood) presently exceed the current effective capacities of those schools. Five other schools (Hills, Hoover, Iftwood, Lemme, Lincoln) are either approaching or at their current effective capacities. Twelve of the 15 elementary schools are facing capacity problems based upon their current effective capacities, Development Potential vs. School Capacity Areas within Iowa City with the greatest development potential are presently not served by elementary schools with significant amounts of remaining capacity. On the other hand, those areas which are most desirable for development in terms of available school capacity are not necessarily the most developable parts of the city given other factors. For example, the largest amount of available elementary school capacity is in Horace Mann and Longfellow schools which serve the Inner City study area. However, this area has the least amount of vacant land available for development. The Peninsula Area, also served by Horace Mann School, is developable once sewer service is extended Into the area. Environmental characteristics of the area, however, affect the "developabllity" of this part of the city. 59 M f/ ELEMENTARY SCHOOL CAPACITIES (Without Temporary Structures) rY of Standard Maximum Effective Enrollment School Classrooms Ca ac Capacity 09.30.88 Coralville Central 19 437 393 415 Hills 13 299 269 261 Hoover 20 460 414 393 Horn 16 368 311 363 IOrkwood 19 437 393 385 Lemme 17 391 351 351 Lincoln 11 253 228 227 Longfellow 19 437 393 323 Lucas 22 506 455 494 Mann 20 460 414 298 Penn 19 437 393 417 Roosevelt 17 391 351 356 Shimek 9 207 186 234 Twain 23 529 476 396 Wood 18 414 372 381 TOTAL 262 6,026 5,399 5,294 While the district has the overall maximum capacity to accommodate 732 additional elementary - aged school children, the enrollments at several elementary schools (Coralville Central, Horn, Lucas, Penn, Roosevelt, Shimek and Grant Wood) presently exceed the current effective capacities of those schools.

Environmental characteristics of the area, however, affect the "developabllity" of this part of the city. 59 M f/ Grant Wood School, the elementary school located in the South Area neighborhood, currently exceeds its effective capacity. Consequently, some South Area elementary school -aged children attend Mark Twain and Hills elementary schools which are located outside the South Area neighborhood. Although Mark Twain and Hills elementary schools have remaining capacity, development of most of the South Area is dependent on extension of a major sewer fine into the area which is a cost commitment the City has not made to date. Full development of much of the South Area is, therefore, not anticipated in the short-range. Shimek, the elementary school serving the North Study Area, is approaching capacity. Development has recently occurred on the east side of this area, but the area's need for an upgraded sewer system and adequate access roads will delay full development of this part of Iowa City. The southwest portion of Iowa City is served by Horn and Roosevelt elementary schools. Ernest Horn Elementary School and Roosevelt School are approaching capacity; yet, this is an area within the city in which development is being witnessed. The rate of growth within the Southwest Area will, to some extent, be limited, however, by sewer capacity constraints in that part of the city. iM Development of the eastern and northeastern portions of the city has been hindered by existing Y ! sewer system constraints. These limitations are expected, however, to be relieved with proposed wastewater system improvements underway. While capacity remains within Hoover School to accommodate some of the anticipated development, Lucas and Lemme schools, which also serve the area, are near their maximum capacities. Solutions to school capacity challenges in eastern Iowa City will eventually have to be identified. "1 Addressing Capac4 Constraints j Many factors influencing the rate at which development occurs are beyond the purview of the local government. The natural qualities of a particular area, the economic climate of the community, the ownership of land, and the rate of population growth in the city as a whole are usually beyond the City government's control but affect how quickly the community grows. Consequently, predictions as to the rate at which undeveloped areas within the city will develop are not made in this plan update. The school district, too, is challenged in Its efforts to accommodate new development. In addition to some of the factors affecting capacities of schools which have already been noted, there are certain Issues currently before the school district which would affect enrollment and the distribution of school -aged children within the district. If the stale legislature mandates all - day kindergarten, space will need to be Identified to house all the kindergartners who currently — share classrooms. The district is also studying the option of establishing a middle school for _ sixth, seventh and eighth grade students. While this alternative would relieve capacity constraints in the elementary schools, existing junior high schools may have to be renovated or expanded to accommodate additional students, M. \ �t In spite of all these variables, available school capacity along with other development parameters and issues have been considered to arrive at a proposed development sequence within this plan update. While a rate of development is not proposed, the plan update sets forth the order in which development of undeveloped parts of the community is expected to proceed. Given the flexibility with which school capacity problems have been ameliorated, the school criterion was not given as much weight in the sequencing determination as was the provision of sewer service or the need to upgrade water lines. Collectively, however, these criteria establish which areas in the community have the greatest development potential. This informa- tion can, in turn, guide the school district in determining the most feasible solutions to capacity constraints be they boundary changes, renovating and expanding existing schools and, perhaps, building new schools. Neighborhood Schools This plan update endorses the continued support of the neighborhood school concept. This concept is based on the premises that 1) elementary schools should be located so that most of the students live within walking distance of the school and 2) the school facilities - open space, gymnasium, or classrooms should be available for use by residents in the neighborhood surrounding the school grounds. Neighborhood schools enhance the neighborhood's sense of identity and Identify a population that is collectively capable of supporting all of the services required within a neighborhood. Solutions to school capacity Issues should be considered within the context of the neighborhood school. it Ii. n f I I I I I ii I I TRANSPORTATION I j7 An urban transportation system Is made up of two basic components - a mode of transport and the infrastructure over which the mode travels. This Plan Update is concerned with the following modes of transportation - private motor vehicles, buses, bicycles, and pedestrians. f The infrastructure dealt with are the streets and sidewalks which comprise the City's trafficways. i .. The private automobile is the dominant mode of passenger travel in Iowa City; however, this Plan recognizes that the other modes - transit, bicycles and walking - play a greater role here ` ` than in many other cities due to Iowa City's size and its large student population. Since the i ,-i mode of travel is intimately tied to the facilities used, accommodations for bicycles and pedestrians in Iowa City's trafficways are also important parts of the system. »r j.; Comprehenslva Plan �. The 1978 Comprehensive Plan Included the following policy statements: - ia. Transit Encourage to the maximum extent possible the use of the mass transit system. 2. Encourage employers to spread employee arrival and departure times through the adoption of flexible time systems, and to encourage their employees to use the mass transit system. J 3. Coordinate and develop the Iowa City transit system with other area transit systems. n b. Maior TraMcways I 1. Provide trafficway Improvements which will facilitate the safe, uncongested, flow of traffic. 2. Protect residential neighborhoods from the adverse impacts of truck traffic by developing a truck -routing network in and around Iowa City. C. Residential Nelahborhood Impact i 1. Preserve to the maximum extent possible the desirable characteristics of existing _ residential neighborhoods. 2. Minimize the negative Impacts of arterial traffic on residential neighborhoods. — 3. Designate potential arterial streets prior to development to ensure limited access, adequate buffers, and sufficient rights-of-way. 4. Minimize commuter parking in residential neighborhoods. d. Blkeways and Walkways 1. Develop a safe, continuous bikeway system which will encourage the use of the — bicycle for transportation and recreation by all age groups. 2. Assure the provision of adequate sidewalks and walkways to allow the safe movement of pedestrians throughout the city. 82 j .I • In the 1983 Update these policy statements were retained. The discussion below will suggest i� changes or re-evaluation of some of these statements. Traftways The network of streets and roads in a city determine, to a large extent, the pattern and timing of development. Adequate access is a critical factor in business location decisions and the timing of residential development, The capacity of streets affects trairc congestion and the sense of whether a community is one in which you can get places easily. The configuration i and function of streets define neighborhoods and add to or detract from the attractiveness of residential areas. Approximately 30% of most cities' land area is made up of streets and sidewalks and public rights-of-way. It is very important, therefore, particularly due to the [ i j permanent nature of streets, that a city be aware of the function, design and placement of its a trafcways and provide for the proper extension of the street network through the subdivision process and the city's Capital Improvements Program. 1. Street Network Plan. A street network plan, including all arterial streets existing and `j proposed, is the first step toward establishing a base from which to make decisions about the layout of future subdivisions and the planned expenditure of public monies for road Improvements. The Johnson County Council of Governments Transportation f i Planning Division will be completing such a plan in FY90 for the entire urbanized area i which Includes Iowa City, Coralville, University Heights and Summit Hills, an unincorporated part of Johnson County within Coralville. Upon completion and acceptance, this arterial street plan should be considered for adoption as part of Iowa City's Comprehensive Plan. 2. Functional Classification and Design Standards. A functional classification system describes the two roles different types of streets fulfill in the community: circulation and access to property. Five classifications are proposed for Iowa City's streets: expressways, primary arterials, secondary arterials, collectors and local streets. As one I moves from expressways to local streets in the classification system, the circulatory function diminishes and the access to property function Increases. The specific characteristics and design guidelines for each category shown in Table 5 establish the relative Importance of each function. Pedestrians are accommodated through the design guidelines by indicating sidewalks along all streets except expressways. The eight foot width shown for walks along arterials is intended to allow for the use of sidewalks by cyclists, If desired. Otherwise, bicycles are treated as vehicles on collector and local streets in accordance with state law. _ The street classification system and design guidelines are used to direct the City in Its evaluation of development proposals for new streets and, In conjunction with a long- range street plan, to prioritize the use of public resources for the extension of major trafncways. Reconstruction or realignment of existing streets and new development or redevelopment on existing streets should also take the functional criteria and the guidelines Into account. It is difficult, however, to Impose all the criteria in the classification system on the existing street network where so many other Tactors have ` determined and changed the function and design of the street over time. The 63 classification system and design guidelines should be used with some flexibility to ultimately achieve the goal of designing streets that adequately serve the land uses abutting them and the community as a whole. Whhin the context of the following policy statements carried forward from the 1978 Plan, the functional classification and design system for streets shown on Table 5 is proposed and adopted as part of this Plan Update. • Provide trafficway Improvements which will facilitate the safe, uncongested flow of traffic. • Minimize the negative Impacts of arterial and truck traffic on residential neighborhoods. • Designate potential arterial streets prior to development to ensure limited access, adequate buffers, and sufficient rights-of-way. • Assure the provision of adequate sidewalks to allow the safe movement of pedestrians throughout the city. 64 I 'I J 1 � 6 I j I i 1 - classification system and design guidelines should be used with some flexibility to ultimately achieve the goal of designing streets that adequately serve the land uses abutting them and the community as a whole.

Major lows City Streets by Classification. Listed below are the major streets in Iowa City by classification. These streets were selected based upon anticipated development or redevelopment in areas served by the streets and/or anticipated street extensions. Streets not listed should be evaluated according to the criteria in Table 5 as land development and trafficway decisions need to be made. In evaluating street Improvements and development abutting any of the existing portion of those streets listed as arterials, consideration should be given to ensure that the arterial function of these streets is not compromised.

Sunset St. Dubuque St. Prairie du Chien 4. Subdivision Design. Generally, residential subdivisions should be designed such that the local streets providing access to individual lots do not also act as trafffcways for through -traffic from outside the subdivision or neighborhood, Collector streets carry the traffic from within the neighborhood to the radial and peripheral arterials which may define the neighborhood. M. I 5. II l Isolating commercial and Industrial areas from high-capacity thoroughfares hurts development and the community. Many commercial establishments thrive on locations near heavily traveled roads and the truck traffic generated by industrial uses is most appropriately channeled to arterial streets away from residential areas. Commercial and Industrial subdivisions should be served as directly as possible by major trafficways. Secondary Access All subdivisions should have a sufficient number of access routes to permit a free flow of traffic. In residential subdivisions, this is particularly important for emergency vehicle access and so that residents along a single accessway are not inordinantly burdened with the traffic of the neighborhood. For these reasons, secondary access will be required, as necessary, In all residential subdivisions. The need for secondary access will be determined by the following factors including but not limited to the size of the subdivision, the topography of the land, the density of housing, the adequacy of existing streets serving the area, and the existing and projected development of adjacent land. In some Instances, due to the ownership of land where secondary access is desirable, the City may wish to participate in acquiring the necessary right-of-way for those developments which the City deems in the public interest to foster. In reviewing development proposals where Insufficient access roads exist and the developer of the land does not own land over which the streets should traverse, it is appropriate under certain circumstances for the City to intervene, In the Interest of the community, to condemn land to provide adequate access. Cities are enabled under Chapter 471 of the Code of Iowa to exercise the power of eminent domain, that is, to take private property for public use. This power is given to cities only for "public purposes which are reasonable and necessary as incident to the powers and duties conferred upon cities." §471.4 Code of Iowa. Fair market value must be paid for the land taken. The policy of the City shall be that the power of eminent domain may be used in areas where the private sector cannot, due to lack of ownership, provide appropriate or sufficient street access and where the City wishes a particular development to take place because It would be in the public interest by: 1. encouraging compact and contiguous growth; 2. providing desirable housing opportunities; and 3. providing the best access to a she In the context of a desirable public street network. 13i AW A development project should be evaluated for Re potential degradation of the environment prior to the City's involvement in condemnation actions to determine It it is in the public Interest to foster such development. Best access shall be evaluated as it relates to the presence of sufficient excess capacity and connecting streets, the least degradation to the environment, and the greatest public good for the least cost. It is the intention of the City that the financial burden of condemnation be borne by the benefitting parties, which may include the developer initiating the project; the owners of the land over which the street traverses at such time as benefit accrues to them; and the public sector. Transportation Modes Various City policies may encourage or discourage the mode of transportation used by Iowa Citians particularly in their home to work trips to the Central Business District. Although the private automobile is the dominant mode of transportation in Iowa City as it is throughout the nation, according to 1980 Census figures a number of people who work in Iowa City use other modes of transportation on a regular basis.

An unstated but active policy of the City has been to reserve parking In the City -owned facilities downtown for short-term (shopper) parking and limit the Issuance of long-term permits (downtown employee parking). T /09/ All of these policies are inter -related, particularly those regarding mass transit and parking. Transit and parking policies are especially critical to the City since substantial sums of public monies are regularly allocated to these two complementary systems. A study of parking needs in downtown Iowa City was completed in January 1989 by the Johnson County Council of Governments. This study pointed out that "there is no current shortage of parking downtown:' I The study went on to point out that there is a perceived deficit in parking due to a number of factors. This perceived deficit continues to elicit public demand for more publicly provided f•• parking. Requests for City -owned parking structures even come from areas just outside of the ! Central Business District. r -i At the same time, Iowa City continues to support its transit system. This system, like all transit systems, depends upon the expenditure of public funds for support. Assuming that energy e costs are reasonable, the availability and ease of parking, real or perceived, directly affect the use of mass transit. i Both systems, parking and transit, fulfill the function of accommodating people's need to get downtown. Both systems under current policy and practice involve the expenditure of public funds. The City should, therefore, undertake the task of integrating its policies relative .i to parking and transit, identifying the needs to be met by each system and the appropriate public response. TRANSPORTATION POLICIES The following policies amend and supercede the transportation policies of the 1978 and 1983 Comprehensive Plans. Trafficways • Provide trafflcway Improvements which will facilitate the safe, uncongested, flow of traffic. • Minimize the negative Impacts of arterial traffic on residential neighborhoods. • Designate potential arterial streets prior to development to assure adherence to all the arterial street standards, particularly those standards addressing limited access, adequate buffers, and sufficient rights-of-way. • Assure the provision of adequate sidewalks and walkways to allow the safe movement of pedestrians throughout the city. • Encourage the development of a river corridor trail system to facilitate pedestrian and bicycle travel. • Provide adequate sidewalk design along arterial streets to enable the use of bicycles as a transportation alternative. 70 101 Subdivision Design • Preserve to the maximum extent possible the desirable characteristics of existing residential neighborhoods through appropriate street design. • Locate high -Intensity commercial and industrial uses near major trafficways. • Provide for adequate secondary access to residential subdivisions through the subdivision approval process. • In Instances where development Is deemed in the public Interest and land ownership restricts provision of the necessary secondary access, the city may Intervene to condemn land for access. • Provide for the extension of trafficwaya to complete the street network. Transit and Parking • Develop a coordinated policy to address the continued support of the mass transit system and the provision of publicly owned parking in the downtown. 71 IMPLEMENTATION The Comprehensive Plan is intended to be a guide for development decisions, It presents general land use patterns and a sequence of development based on certain adopted policies. To carry out the policies and the sequence of growth projected In the Plan, various tools may be used. The most common tools are the zoning ordinance, subdivision regulations, and the capital Improvements program; these tools are explained below. To realize the City's intent of making this Plan a vital and useful document, an Action Plan will be developed as the natural i next step in the comprehensive planning process. The Action Plan will outline regulations, ;., incentive programs, and other specific measures to carry out and coordinate the policies stated in this update. With approval of the Action Plan by the City Council, specific legislation will be �+ drafted for adoption. Zoning w I i Pursuant to Chapter 414 of the Iowa Code, the City has adopted zoning regulations which implement the ranges of population density and locations for various types of land uses which are shown on the Comprehensive Plan Map. The Zoning Ordinance divides the city into districts and regulates land uses within those districts in accordance with this Comprehensive Plan. Careful consideration is given to making the various Zoning Ordinance classifications compatible and consistent with the land use designations indicated on the Comprehensive Plan Land Use Map, Table 6 indicates the types of zoning designations that are intended to coordinate with the various Comprehensive Plan Land Use Map designations. An examination of Table 6 reveals that within several of the Comprehensive Plan Land Use Map designations, more than one zoning district designation may be appropriate. For residential land uses in particular, there is overlap so that a zoning district which is compatible within the 6-16 DU/A designation is, for example, also compatible within the 16-24 DU/A designation. - In drawing actual zone boundaries, such flexibility will permit transition districts between areas !' of high residential density and lower residential density, between commercial and residential districts, and between intense and less intense commercial areas. _ The fact that the Comprehensive Land Use Map shows only generalized land uses means that it will not in all cases reflect small areas of existing use which may be zoned to reflect such use or density. This recognizes that while the Land Use Map depicts the long-term goals for development within the City, the zoning ordinance must consider the reasonableness of a classification as applied to a particular property. Therefore, in Instances where a zoning classification In strict accordance with the Land Use Map would appear to cause such harm to a property owner as to outweigh the benefit derived from strict conformance with the Comprehensive Plan, a given property may be zoned to allow an existing use. 72 FI.

(P) n AM ,a Subdivision Regulations The City of Iowa City's review and approval power over subdivision plats gives the City another means of implementing its Comprehensive Plan. Subdivision regulations ensure the compatible growth of contiguous areas by mandating the provision of streats, sewers, and water to the boundaries of specific developments. Subdivision regulations may also carry out specific policies of the City such as requiring secondary access in appropriate cases, providing measures for the acquisition of neighborhood open space, and protecting the environmental assets of Iowa City. It is in the subdivision regulations that a City may institute the application of impact fees to meet the needs generated by a specific development project. Impact fees are only for improvements that benefit the development paying the fee and should be consistent with the City's Capital Improvements Program for community -wide facilities. Capital Improvements Program The subdivision regulations and the zoning ordinance direct the quality and intensity of development when it does occur. However, it is the capital improvements program which can manage the timing of development in given areas to ensure that no development is premature and beyond the limits of efficient municipal service provision. The capital Improvements schedule outlined below (Table 6) corresponds to the proposed development sequence of the Plan. The schedule addresses projects that involve the provision of water, sewer, and streets - those areas in which the public provision of a capital Improvement can effectively determine the timing of private Investment. The Capital Improvements Program links the development policies established in the Comprehensive Plan to the future expenditure of funds and provision of capital improvements. The City systematically reviews all capital projects for consistency with the adopted goals, objectives, and policies established in the Comprehensive Plan. Specific positive and negative impacts of capital projects can be considered in light of existing municipal policies. The Capital Improvements Program also serves as a strong financial management tool. State law and sound fiscal policy Impose limitations on the ability of the City to undertake major capital projects. By systematically evaluating capital projects, prioritizing those projects in terms of need, and anticipating financial requirements well in advance, the management of municipal debt and debt service requirements is enhanced. The operating budgets adopted annually throughout the period covered by the Comprehensive Plan are not generally considered to be major implementing devices. However, many of the policies established in the Comprehensive Plan need to be considered in the operating budget. Facility maintenance, code enforcement, housing rehabilitation, traffic control, zoning administration, subdivision plat review, and other activities required to achieve the goals and objectives set forth In the Plan are funded annually In the City's operating budget. The level of service provided by the departments carrying out these functions will have a direct Impact on the City's ability to carry out the policies set forth and the goals and objectives established in the Comprehensive Plan. 78 101 H rq It I 11�� Table 7, Capital Improvements Schedule PHASE I: Sewers: Upgrade 8" sewer west of Amhurst Water: Extend 12" water along Scott Blvd. Extend 12' water, Muscatine Ave. to Heinz Road.

At least half of the Northeast Area remains undeveloped and in agricultural use. tack of sewer service and street access to a majority of the area have contributed to its undeveloped state. An assessment of — development potential and appropriate land use is addressed in this study. j ^� Comprehensive Plan The 1978 Comprehensive Plan envisioned the Northeast Area developing primarily as low- i density residential uses with pockets of medium -density residences along North Dodge Street, east of the American College Testing Corporation (ACT), and north of Rochester Avenue between First Avenue and Scoff Boulevard. Surrounding the I.80/Highway 1 interchange, the w designated land use was office research park and commercial. The 1983 Update dropped any projected medium -density residential use, retained the predominantly low-density single family residential character, and increased and relocated the area for office/research development. This study will consider the continued appropriateness of these types of development in this area. Issues 1. Sewer Availability. The Northeast Trunk Sewer system services an area approximately 900 acres In size within the existing corporate limits. Approximately 200 of these acres _ located north and east of Hickory Hill Park and the Ralston Creek stormwater detention _- facility, will be sewerable at a density of 22 people/acre upon completion of the wastewater system improvements. This density calculation is based on serving only the area within the corporate limits, including those properties served by the Highlander _ lift station north of 1.80. The remaining 700 acres in the easterly half of the Northeast Area, will require the extension of additional trunk lines off the Northeast Trunk before development can occur. Capital Improvements will also be necessary for full development of the office/research area north of 1-80; these Improvements Include expanded capacity in the lift station and line extensions. Depending upon the type and — extent of office, research and development uses both north and south of the Interstate, the density of development In the entire study area may be diminished to less than 22 people/acre; 9-12 people/acre is an acceptable urban density. Even If 695 acres were — developed for office research and development center use, sufficient capacity would remain to accommodate an urban residential density of 9 people per acre. i_ m /09� 2. Transportation. The two major transportation issues associated with the Northeast Area are: extension/improvement of major trafficways and provision of secondary access as development occurs. The Northeast Area will ultimately be served by four major traffic - ways: Rochester Avenue, First Avenue, Scott Boulevard and North Dodge Street. Rochester Avenue and North Dodge Street exist, First Avenue has been extended into the area to a point north of Ralston Creek, and Scott Boulevard remains an arterial concept for the future. North Dodge Street, Rochester Avenue, First Avenue and Scott Boulevard will serve as the basis for a street network made up of collector and local streets feeding into the developing sections of the Northeast Area. a. First Avenue First Avenue will serve as a major north/south traffioway for the Northeast Area. First Avenue provides general access to commercial and industrial areas in south Iowa City and direct access to residential lots on Iowa City's east side. When completed, First Avenue will be the most direct connection between Highway t in northeast Iowa City and Highway 6 in southeast Iowa City. First Avenue will function as an arterial even though existing portions are designed to residential collector and local standards. Future extensions of First Avenue should incorporate arterial design features appropriate to the volume of traffic which is expected to utilize the street, while existing sections may need to be modified so that First Avenue adequately serves the Northeast Area. The policy of the City has been to extend streets through the development process. That is, streets are constructed as development occurs and with the financial participation of the developer. The only reason to deviate from this policy and place the burden of extending streets on the taxpayers generally is if the street extension is required to benefit the community as a whole. First Avenue will be extended to connect ultimately with North Dodge Street some day and, at that time, will decrease traffic flow on North Dodge Street south of the Intersection with First Avenue. Recent capacity studies done on North Dodge Street demonstrate that there does not exist sufncient traffic on North Dodge Street now to warrant the expenditure of public funds to extend First Avenue now. The extension of First Avenue may be precipitated, however, by the need for secondary access In the area to facilitate continued residential development or to accommodate possible development plans for the American College Testing Program (ACT), Consistent with past policy, funding for the extension will be provided, at least in part, by the benefitting developer. The alignment of First Avenue was discussed In the 1983 Plan Update. Based on topographic, functional and cost factors, the preferred alignment is along a ridge line that would connect First Avenue with Old Dubuque Road (or Scott Boulevard when extended) at a point on property owned by the American College Testing Program (ACT), ACT is in the process of developing a master plan for the 220 acre site they own. Upon completion of their plan, ACT may 81 propose alternate alignments for First Avenue and Scott Boulevard. At that time the City may wish to reconsider the preferred alignments for these roads, keeping in mind the impact the alignments will have on the function of the streets and on the existing development. Cost and environmental issues should also be considered. b. Scott Boulevard As with First Avenue, the alignment of Scott Boulevard may warrant re-evaluation upon completion of ACT's master plan. The preferred alignment of Scott Boulevard in the 1983 Plan follows a ridge line and curves westward to intersect with First Avenue through the middle of ACT's 220 acres and could have a significant effect on the development of the area. Scott Boulevard will be designed as an arterial intended to carry traffic between I-80/Highway 1 and areas in southern Iowa City and to collect traffic from collector and local streets In the Northeast Area generally. Scott Boulevard will be constructed, for the most part, as development occurs with the financial participation of the developer. C. North Dodge Street Capacity As development proceeds in the Northeast Area, the North Area and parts of the County, North Dodge Street will be expected to carry a significant share of the new vehicle trips from the developing areas to the central city. The capacity of North Dodge Street to continue to function as a two-lane arterial street was evaluated recently in response to a proposal by the Public Works Department to widen the street to four lanes between Governor Street and 1-80. The study, completed in May 1987 by the Johnson County Council of Governments Transportation Planning Division, concluded that currently the street functions adequately but that with full development of feeder areas signalization at certain intersections and expansion of the street to four lanes may become necessary. A copy of the study is Included in the Appendix. The study is based on the development potential as determined by current zoning of 435 acres, 100 acres of which is outside the City limits. Given the slow rate of growth of the City and the County and the development sequence of this Plan, It is unlikely that Improvements to North Dodge Street will be required In the next 5.10 years, d, Secondary Access Residential development in the south central portion of the Northeast Area has reached a practical limit given the difficulty of providing secondary access to the area. Further development cannot occur until either Scott Boulevard is completed to Highway 1 and the interior local street network is extended to Scott Boulevard, First Avenue is extended north to Dubuque Road, or the local street network is looped back to Rochester Avenue. 82 /09/ I _. Normally, the extension of streets is the responsibility of the private developer with the City sharing in the cost for collector and arterial streets. The developer's responsibility includes engineering a street layout which is acceptable to the City and dedicating the street and the underlying right-of-way for public use. As building progresses beyond the edge of existing development and projects into agricultural areas, the adequate extension of streets to create a street network becomes more difficult. Individual developers do not necessarily control all the land over which a desirable street pattern would be Imposed. It then becomes a matter of public interest, that in order to obtain the most workable street pattern for the public good, government must involve itself in a cooperative effort with the private sector to ensure the desired street network is created. The tool the City may use is its power of eminent domain. In the Transportation section of this Plan, a policy is adopted which permits the City to Intervene, in certain instances, to use its power of eminent domain to acquire right-of-way for secondary access. The cost of this public effort should be calculated into the timing of development, and all other factors being equal, may move the development of the Northeast Area back in the sequence of development, delaying its growth. 3, Topography & Residential Development. The area between the future alignment of First Avenue and Scott Boulevard extended represents an area best suited to low- density residential development. This area is characterized by severe topographical constraints in the form of ridges and ravines. Developments in this area should be planned with an emphasis on adapting to existing terrain. Although a density range of 2-8 DU/acre may be most appropriate, larger lot sizes in some locations may be necessary to provide home sites that are sensitive to this rugged topography. This area Is also well suited for planned development housing (PDH), which can allow flexibility in the placement and clustering of buildings, the provision of streets, and the use of open space. A planned development can promote efficiency by minimizing the network of utilities and streets for a given number of lots, while allowing development to occur In a manner sensitive to the area's natural features. As a means of implementing this policy for the area, the City may consider imposing planned development zoning on designated areas with standards which require development sensitive to the natural features valued, Use of this tool will require re-evaluation of the planned development overlay zone. 4. Office Research & Development Centers. The 1978 Comprehensive Plan designated an area along North Dodge Street west of the easterly leg of Dubuque Road to 1.80, an area south and east of ACT, and an area north of the 1.80 Interchange as suitable for future office research park (ORP) development. The 1983 Comprehensive Plan Update recommended that a 118 -acre area just south of 1-80 and east of ACT represented a better site for the long-range development of research parks than the area along North Dodge Street near Dubuque Road, With an amendment to the Plan in 1987, research and development centers were also considered as appropriate land uses for parts of the Northeast Study Area north oft -80. 83 /to 9/ The area northwest of the I.80/Highway 1 Interchange was also envisioned by i the 1983 Comprehensive Plan Update to develop as office/research parks. — Currently, National Computer Systems (NCS) Is the only development in this quadrant. The area has an undulating topography near 1-80 and then slopes down to relatively level land to the north which is presently in agricultural use. This area Is suited to office/research park development given the interesting and aesthetically appealing nature of the topography and the ready access to major traffic corridors and motels. Access to the Interior of the area currently zoned — ID -ORP is difficult given existing development on the NCS lot to the east and the existence of Rapid Creek to the north. These factors may limit the Interior parcel's marketability. Visibility and the exposure that occupants would have from 1.80 is limited to the southern -most portion of the area; the remainder of the 84 Ii _ Research and development centers are research parks with a greater emphasis on production than is found in office/research parks where only prototype manufacturing i takes place. In a research and development center, prototype manufacturing may evolve into full scale production of such items as electronics and computer equipment, medical instruments or pharmaceuticals. The amenities of landscaping, high quality design, and large setbacks (at least along the boundaries) that one expects in an office/research park are also critical to the successful development of a research and development center. Research and development centers may also be designed with smaller lot sizes than the more campus -like development envisioned for an office research park. The zone designed for these uses (RDP) requires the preparation of a Master Plan for the development. The plan must show the amenities necessary for a center and the measures to be taken to protect residential development In the vicinity. I The net effect of this plan review process can be the achievement of a development sensitive to any natural features present while utilizing smaller lot sizes, Research and development centers are intended to be compatible with and may, therefore, be located in areas near office/research parks or residential development. I � J a. Highway 1'lInter3tate 80 Interchange. The northeast quadrant of the Highway 1/Interstate 80 Interchange has been zoned for office and highway commercial uses since 1982 and has been developing accordingly. The plan amendment adopted in 1987 stated that the area beyond the existing commercial and office uses is more appropriate for a mix of office/research and research/development uses than for strictly office research park development as was envisioned in the 1983 Comprehensive Pian Update. The change in policy was supported by three factors: an existing smaller lot (two acres/lot) subdivision; a sense that Iowa City's economic development efforts would be best served by accommodating small, evolving research and technology firms which would eventually expand to product development; and the existence of a larger, topographically elevated -- site, visible from the interstate, that would continue to be appropriate for large office/research park development. Given the above conditions, future develop- ment northeast of the 1-80/Highway 1 interchange should continue to be for office —. and office/research park uses where possible with potential for research and development centers being fostered. The area northwest of the I.80/Highway 1 Interchange was also envisioned by i the 1983 Comprehensive Plan Update to develop as office/research parks. — Currently, National Computer Systems (NCS) Is the only development in this quadrant. The area has an undulating topography near 1-80 and then slopes down to relatively level land to the north which is presently in agricultural use. This area Is suited to office/research park development given the interesting and aesthetically appealing nature of the topography and the ready access to major traffic corridors and motels. Access to the Interior of the area currently zoned — ID -ORP is difficult given existing development on the NCS lot to the east and the existence of Rapid Creek to the north. These factors may limit the Interior parcel's marketability. Visibility and the exposure that occupants would have from 1.80 is limited to the southern -most portion of the area; the remainder of the 84 area slopes north and away from the interstate. However, with proper design, visibility on the southerly portion of the site can be maximized and it is believed that the area can develop as a successful office/research park. The area southeast of the 1.80/Highway 1 interchange represents the most desirable location for office/research park development. There is a substantial portion of the area visible from 1-80 as the land slopes up and away from 1-80 and then Is relatively flat. There are several stands of trees and the area is readily adaptable to the campus -like environment associated with office/research park development. Uke the other areas abutting the 1.80/Highway 1 interchange, this area has good access to major traffic corridors and motels. -_ b. North Dodge Street. As noted above, the 1978 Comprehensive Plan designated all of the area from the 1-80 interchange southwest along the south side of iHighway 1 beyond the easterly leg of Old Dubuque Road as appropriate for office/research park uses. This area Included the American College Testing (ACT) property, the residences on the wooded knoll southwest of ACT, and the Gatens property (between the north -south drainageway of Ralston Creek and Old Dubuque Road). In 1983, the Plan was amended to designate the area along North Dodge Street residential and an area of land directly south of 1.80 and east i of ACT for office/research park use. With the evolution of research and of development centers as an off -shoot of office/research parks, it may be appropriate at this time to consider more land for these uses and redesignate - the property along Highway 1 for office, research and development centers. This i would envision the development of this area for either an office/research park or a research and development center rather than for residential use. The property in question has frontage along Highway 1 and along Old Dubuque Road west of ACT. The topography is hilly with ravines providing areas of tree cover. Development is likely to occur on the ridge tops or plateaus. Visibility from Highway 1 is limited and from 1.801s nonexistent; however, there does exist -' easy access to 1.80 via Highway 1. if the City is interested in providing a number of different areas for research and development centers or of- fico/research park uses, this area offers such an opportunity as a continuation of the ACT campus concept. The natural amenities that exist there combined with access to Highway 1 and proximity to 1.80 provide a valuable community resource as a site for an office, research and development center that would provide leverage for other types of growth throughout the City. Development under a master plan, required for research and development centers, could also ensure that nearby residential development and the Highway 1 entranceway to Iowa City is safeguarded and have the effect of preserving the natural features that make this area attractive. 5. Annexation. The 1983 Comprehensive Plan Update addressed the possible annexation of 418 acres immediately east of the Northeast Study Area and the City's eastern corporate boundary. It was pointed out then, that the area wasn't needed for residential development and annexation was undesirable. 85 /09/ _ Since the 1983 Comprehensive Plan Update, there hasn't been a desire on the part of the City or private developers to annex the 418 acres. Until such time that the Northeast Area, already in the City's corporate boundaries, nears full development, annexation of the 418 acres would not be desirable since services would need to be extended and the space is not required to accommodate anticipated growth. Residen- tial development can take place in the next 5-15 years in other areas of the City, as indicated in the development sequence of this Plan. The long-term market demand for j housing in Iowa City and the willingness by property owners to develop their land will precipitate any consideration of annexation of this area; it is not anticipated that the _ area east of the City's corporate limit will be annexed within the next fifteen years. 6. Schools. The Northeast Study Area will eventually reach full development and may, at that time, require additional school facilities, The total undeveloped residential portion of the Northeast Study Area is approximately 597 acres in size and will yield about 999 building lots, based on the area's topography and previously platted subdivisions in the area. The development sequence of this plan projects development of only 175 acres for residential use in the next 10 to 15 years. Current single-family subdivisions in the I' Iowa City area have had a 60/40 split between three-bedroom and four-bedroom homes. Using national school -aged children multipliers, based on the above 60/40 split, approximately 260 additional school aged children can be expected in this time period. f Once the Northeast Study Area reaches full residential development, an additional 739 children may be anticipated using the same ratios and multipliers, Full residential development in the long-range, generating this many children, may dictate building new facilities if busing or boundary changes become impractical or capacity in the school system is reached city-wide. 7. Open Space. The Northeast Area encompasses two of the open space districts outlined In the Neighborhood Open Space Plan - Hickory Hill and Upper Ralston Creek. — Due to the presence of Hickory Hili Park, there is no open space deficiency in the Hickory Hill district. In the Upper Ralston.Creek district, there is a deficiency of 11 acres based on the projected residential population for full development of the area. i i Development Sequence The Northeast Area is divided Into two subareas for purposes of devisin development g a p nt sequence. The division is shown on the Sequence of Residential Development map and roughly follows a line along the Scott Boulevard alignment on the north and along property lines on the east. Those properties west of the line are expected to develop in Phase ll, or within 10.15 years, depending upon the overall rate of growth In the City. Land to the east of the line should develop in later phases of growth. 86 i Irl i v.7 AM i Ii RECOMMENDATIONS L.� 1. Future residential development should be discouraged until secondary access can be provided in the Northeast Study Area. The City will, with the financial participation of the developer, enter into negotiations to acquire the necessary right-of-way to develop an adequate street network in those instances where the private sector cannot ireasonably do so. 2. Large lot development and planned development zoning may be appropriate in this area to require development sensitive to the natural features which exist. 3, The Comprehensive Plan Map was amended in 1987 to classify the area north and rI northeast of the Highlander Inn as appropriate for office, research and development J centers. The area west of ACT, southeast of Highway 1 and south of the easterly leg of Old Dubuque Road, should also be redesignated to this land use category. I� 4. Annexation of the 418 acres east of the study area should not be encouraged as there "j is adequate developable land existing in the city. u 5. No school sites need be designated in the study area at this time. With full development of the area, the need for an additional facility or some alternative should be anticipated. 6. Neighborhood open space should be provided in the area shown as the Upper Ralston —� Creek District in the Open Space Plan. 87 lb mmm■l ■■■■■! moons! ■■■■■! ■ l_ OPEC :p"S ■ELM■ /D9/ EAST AREA STUDY Study Area I The East Area of Iowa City is bound on the north by Rochester Avenue, on the east by the corporate boundary, on the south by U.S. Highway 6, and on the west by First Avenue. The current land use in this area is predominantly single-family residential, with multi -family residential/commercial centers near First and Muscatine avenues and at First and Rochester avenues. Undeveloped multi -family residential zoned land exists along Scott Boulevard near Court Street and surrounds a tract in the northwest quadrant of the intersection of Court Street and Scott Boulevard which Is zoned for neighborhood commercial purposes. i The Iowa Interstate Railway right-of-way provides a barrier between the residential development of the Village Green subdivision and the industrial uses within the Business Development Incorporated (B.D.I.) industrial park to the south. Development west and north of the study area is, for the most part, residential or undeveloped and is compatible with the largely residential land use of the study area. County land east of Scott Boulevard is generally undeveloped with the exception of Modern Manor, Inc. and Sunrise Mobile Home Village, J manufactured housing developments. Current land uses Include farming and scattered residential uses, Land within one mile of the City's eastern corporate boundary is predomi- nantly zoned RS, Suburban Residential, which permits large lot, single-family residential J dbVelopment. One mile further east, A-1, Rural, zoned land predominates. Comprehensive Plan The 1983 Comprehensive Plan Update projects continued residential uses throughout the area, ry with those currently undeveloped portions along the eastern corporate boundary and along Rochester Avenue developing as residential uses at low to medium densities. A neighborhood commercial center, indicated at the intersection of Court Street and Scott Boulevard, is expected to serve the immediate area. The undeveloped portions of the East Area are included in Phase III of the development sequence of the 1983 Plan Update. Improvements to Scott Boulevard and completion of wastewater system Improvements were expected to precede development of these undeveloped tracts. Issues The areas of potential residential growth in this part of the City consist of approximately 270 acres that generally Ile along the eastern periphery of the study area. The timing and density ' of future development are governed to a great extent by the availability of municipal sewer service. Different sewer constraints distinguish portions of the East Area. 88 { V AM I Most of the undeveloped land lying south of Muscatine Avenue requires the use of lift stations and force mains to access the municipal sewer system. The land north of Muscatine Avenue, however, can generally be served through a gravity feed network. The following discussion of development Issues and the proposed sequence of future development in each of these areas Is addressed with these distinctions In mind. —. 1. Municipal Sewer Service. The pivotal issue affecting future development of the East r Area is the impact of proposed sewer system improvements on resolving peak wet - weather surcharging conditions in the Rundell Street Trunk Sewer downstream from the ! study area which have been a deterrent to full development of the area. The Southeast and the Lower Muscatine trunk sewers which service the study area empty into the Rundell Street Trunk Sewer and, consequently, contribute to any overload on that line. At the present time, additional development on the east side would add to existing surcharging conditions. Construction of the new Water Pollution Control Plant (WPCP) P-1, and the Southeast Interceptor System, however, will alleviate sewer capacity problems in this area. The new plant, the outfall sewer leading from the plant to the Iowa River, and the Snyder Creek segment of the Southeast Interceptor Sewer are expected to be completed by August, 1990. Phases I and II of the Ralston Creek segment of the Southeast Interceptor Sewer, the northern portion of this system, will be completed by June, 1991. j I a. South of Muscatine Avenue. Lift stations currently in use in this area have some excess capacity. However, wet -weather capacity constraints within the ry Lower Muscatine Trunk Sewer and the Rundell Street Trunk Sewer System _I suppress opportunities for full development of the Village Green residential area plus the development of the industrial park south of Village Green. I The remaining 130 acres available for residential development south of Muscatine Avenue require the use of a lift station to tie Into the municipal sewer system. i While the Village Green lift station would have to be expanded to accommodate full development within the Village Green subdivisions, proposed Improvements to the City's wastewater collection and treatment system are expected to be i capable of accommodating this residential development. i — Currently, the Lower Muscatine Trunk Sewer also carries the flow from the Heinz lift station which serves B.D.I. and from gravity feed areas downstream from the force mains which transport sewage from the lift stations into the service area of the Lower Muscatine Trunk Sewer. The Lower Muscatine Trunk Sewer cannot, however, accommodate the complete development of both the Village Green area and the industrial park. With construction of the new sewage treatment plant and Interceptor system, sewer capacity problems south of Muscatine Avenue would be alleviated. Based upon the types of industries that have historically located within Iowa City, these Improvements would permit development of the Industrial park and the remaining 130 acres within Village Green at a density equivalent to 13 people/acre (1983 Update estimate). if new Industries locating within the city demand an excessive amount of sewer service, however, the density of development within new residential areas may be reduced. b. North o/ Muscatine Avenue. Developable land north of Muscatine Avenue and east of First Avenue is serviced by the Southeast Trunk Sewer. There are existing restrictions in this trunk line which constrain development of the area. _ With completion of Phases I and 11 of the South Ralston Creek segment of the Southeast Interceptor Sewer by June, 1991, there will exist enough capacity to provide sewerage to all of the unplatted lands within the portion of the East Area north of Muscatine Avenue. The development potential reaches 88 people/acre for the land lying along Scott Boulevard between Muscatine and Rochester avenues and 34 people/acre for an area south of Rochester Avenue and west of Amhurst Street; the lower development density in this area is due to a restriction in an eight -inch line serving this area. Thus, with completion of t proposed wastewater system improvements, there is sufficient sewer capacity in the northern portion of the East Area to accommodate low to high density residential development. 2. Traftways. Recently completed Improvements to Scott Boulevard between Court Street and Rochester Avenue permit the traffcway to function as a primary arterial street linking northern and southern Iowa City in the eastern part of the community. The principal purpose of this roadway is to facilitate circulation. If Scott Boulevard is to serve Its intended purpose, access from Scott Boulevard to any new development in the study area should be limited. A limited number of collector streets connected directly to Scott Boulevard is necessary, however, to obtain efficient transit system loops and to provide access to residential neighborhoods. Between Muscatine and Rochester I avenues, the necessary collector streets are in place. With full development of the Village Green subdivision south of Muscatine Avenue, a limited number of collector streets with access to Scott Boulevard will need to be provided. — 3. Schools. The study area Is within easy access of City High School, Southeast Junior High School, and Lucas and Lemme elementary schools. Lucas School is presently at capacity and Lemme School is approaching capacity. Full residential development of the East and Northeast areas as well as development in other areas is expected to challenge the capacities of existing schools in Iowa City. The undeveloped residential portion of the East Study Area is approximately 270 acres 7 I size of which about 250 acres will most likely develop for single-family residential use, About 20 acres of land in the vicinity of a proposed neighborhood commercial center north of Court Street and west of Scott Boulevard may develop for multi -family residential use at low to medium densities. Based upon the number of lots within previously platted single-family subdivisions In the East Area, 250 acres of undeveloped, single-family residentially zoned land would yield about 826 single-family units. 90 i ■ r - About 65 percent of existing single-family homes in the East Area are three-bedroom units; 35 percent of the dwellings are four-bedroom units. By applying national school - aged children multipliers, which are based on housing unit size, to the 826 potentially new single-family dwelling units In the East Area, it is projected that approximately 710 school -aged children would occupy these new single-family homes once the East Area reached full development. Tracts that will most likely develop for multi -family residential use may also generate additional school -aged children. If capacity in the school system is reached city-wide, consideration may have to be given to accommodating children living within these new residential areas by renovating and/or expanding existing schools or constructing new schools. 4. Parkland/Open Space. Active and passive recreational facilities are provided in the area on the grounds of Southeast Junior High School, Lucas and Lemme schools and in Pleasant Hill, Court Hill, Mercer and Scott parks. Recreational needs, to some extent, are also satisfied on the Regina Schools property, in Hickory HIII Park and at Hoover School west of the study area. Based upon criteria applied to undeveloped portions of the East Area, the Open Space section of this Update concludes that existing facilities will satisfy the open space needs of area residents. No new park facilities in the East Area are, therefore, contemplated. r, RECOMMENDATIONS 1. With provision of adequate municipal sewer service to this area, development should proceed in a manner consistent with the land uses recommended in the 1983 Comprehensive Plan Update. 2. Following sewer system improvements, undeveloped areas south of Rochester Avenue and north of Muscatine Avenue may be developed without installation of major Infrastructure improvements. Development of these tracts should then be encouraged. Full development of undeveloped residential land south of Muscatine Avenue, while contiguous to existing development, is dependent upon upgrading the Village Green lift station. Development south of Muscatine Avenue should, therefore, be delayed pending completion of development in the northern portion of the East Area or until a private commitment is made to upgrade the Village Green lift station, 91 I 1 I 'LI -I I I SOUTH AREA STUDY Study Area The South Area includes land within the corporate limits which is located south of Highway 6 and east of the Iowa River. The area's delineations by the Iowa River, by the heavily used, four -lane divided Highway 6 truck route, and by the corporate boundary line on the south and east, Isolate it from adjacent neighborhoods. Both residential and commercial uses have - developed in the area but a large portion of the land remains in agricultural use. Comprehensive Plan f The 1983 Comprehensive Plan Update envisioned that, in the long-range, the South Area would develop primarily for low- to medium -density residential uses, with intensive commercial and general commercial uses concentrated in the northwest portion of the study area south of Highway 6 between the Iowa River and Broadway Street. The Plan anticipated that in the short-range, however, low density residential development of uj over 400 acres of land immediately south of existing residential development would be delayed, The delay was attributed to existing constraints within the municipal sewer system serving the i South Area. In addition, although the new water pollution control plant was, in 1983, proposed on a site adjacent to the South Area, the proposed Improvements did not call for extending a trunk line into this area concurrent with construction of the wastewater facility. Short-range residential development opportunities within the South Area were, therefore, restricted to areas that were more immediately sewerable. Issues 1. Sewer Availability. Due to topographic restrictions and existing constraints in the _ municipal sewer system serving the South Area, a limited amount of sewerable land exists south of Highway 6 and east of the Iowa River. Over 600 acres of undeveloped land remain in southeastern Iowa City but only about 90 acres are presently sewerable. Wet weather surcharging conditions in the South Side Trunk Sewer and limited capacity j In the Keokuk Branch of this trunk sewer system restrict future residential development in the South Area. i Allowing development in the service area of the South Side Trunk Sewer without addressing capacity problems would aggravate wet -weather surcharging conditions. Increased surcharging in the South Side Sewer would adversely affect businesses tied directly to this sewer, If surcharging occurs far enough upstream in the South Side Trunk Sewer, the Keokuk branch of the system would also surcharge and Impact j businesses and homes served by this segment of the South Side Trunk Sewer System. 1 I Wastewater system improvements proposed in the 1963 Update to the Comprehensive Plan, which would have permitted development of portions of the South Area, have not been constructed and the location of the new water pollution control plant has been shifted to a tract of land located southeast of the site identified in the 1983 Update. As a result of this shift, an outfall sewer which was designed to run along South Gilbert Street to the proposed plant will no longer be installed; portions of the South Area i within the service area of this sewer will, therefore, not be immediately developable. While construction of the new water pollution control plant is intended to solve many city-wide sewer restrictions, the South Area will not substantially benefit from projected Improvements to the system. Although the new Southeast Interceptor Sewer will transect the eastern portion of the South Area, proposed wastewater system Improvements do not include extending a trunk line from the interceptor sewer Into the South Area. Until this trunk sewer is extended, development within the area is generally limited to parcels which are presently sewerable. 2. TraHlcwsys. Until a trunk sewer is extended from the Southeast Interceptor Sewer into the South Area, the existing collector and arterial roadway system serving the South Area, namely Gilbert and Sycamore streets and Highway 6, is expected to adequately accommodate the study area. Extension of a trunk sewer into the area, on the other hand, will permit development of a significant portion of the South Area. To accommodate the amount of traffic that is expected to be generated by future "• residential uses, an arterial trafcway connecting Gilbert and Sycamore streets and _ perhaps Scott Boulevard extended, is recommended. In the short-range, however, existing facilities can serve the residential and commercial needs of the South Area. 3. Schools. In view of development limitations in the study area due to the lack of sewer availability, an Increase in the elementary school population attributable to development within the South Area is not anticipated. In the short-range, Mark Twain, Grant Wood and Hills elementary schools are expected to continue serving the area. As the South Area reaches full development, additional school facilities may be required. The undeveloped residential portion of the South Study Area is approximately 568 acres In size of which about 420 acres are expected to develop for single-family residential use. The balance of the residential portion of this area may develop for single-family residential use or for residential purposes at slightly higher densities. Based upon the _ P P 9 Y 9 P area's topography and the size of previously platted single-family residential lots in the South Area, the 420 acres of single-family residentially zoned land would yield about 1,582 single-family dwelling units. About 90 percent of existing single-family homes in the South Area are three-bedroom units; ten percent of the dwellings are four-bedroom units, By applying national school - aged children multipliers which are based on housing unit size to the 1,582 potentially new single-family dwelling units in the South Area, it Is projected that approximately 1,095 school -aged children would occupy these new single-family homes once the South Study Area reached full development, Additional school -aged children are also 93 /09/ ! I I 1 expected to occupy the residential dwellings that may develop at slightly higher densities in the western portion of the South Area. The number of school -aged children expected to be generated by residential development in southern Iowa City may dictate jbuilding new facilities if capacity in the school system is reached city-wide. In the short- range, however, no elementary school sites need be designated in the study area. I i! 4. Parks/Open Space. In conformance with the urban environment policies of this plan update, greenbelts should be encouraged along the Iowa River. Greenbelts along rivers and creeks not only provide passive recreational opportunities, but help maintain water quality and reduce the risks of flooding and erosion. j Two of the open space districts outlined in the City's Neighborhood Open Space Plan - Wetherby and Grant Wood - are Included in the South Study Area. The Wetherby Open Space District includes that portion of the study area between the Iowa River and r' Sycamore Street. Wetherby and Napoleon parks presently provide recreational ` opportunities within this district. If the westernmost portion of the South Area should develop for residential uses at densities higher than single-family residential uses, i' additional parkland may be needed within the Wetherby district to accommodate this l development. Future residential development east of Sycamore Street will utilize recreational facilities �l at Grant Wood School and Fairmeadows Park but additional parkland may be needed to serve the needs of the projected residential population once the Grant Wood Open _I Space District is fully developed. 5. Proposed Residential Development Sequence. Recognizing varying development limitations, the South Area is divided Into two subareas for purposes of devising a residential development sequence. The division is based upon the extent of infrastructure Improvements required and the degree of continuity to existing i development. Depending upon the overall rate of growth in the city, the subarea Identified as the Near South Area in the development sequence section of this Update Is expected to develop within 10-15 years. The balance of the South Area should develop in later phases of growth. I_ RECOMMENDATIONS _I 1. In the short-range, limited development which can be served by remaining capacity within existing sewer lines may occur but should be carefully monitored to prevent surcharge problems to downstream users. Development of much of the South Area is dependent upon a private commitment to extension of a trunk sewer Into the area. With provision of adequate municipal sewer service to this area, development should proceed In a manner consistent with the land uses recommended in the 1983 Comprehensive Plan Update. .t i i 94 i A Mi 2. An arterial trafficway connecting Gilbert and Sycamore streets and possibly Scott Boulevard extended will be needed to accommodate full development of the South Area. 3. No school sites need be designated In the study area at this time. With full development of the area, the need for additional facilities or some alternative should be anticipated. 4. Reservation of open space along the Iowa River should continue to be encouraged. Coincident with full development of the South Area, additional parkland may be needed In the area. I r. 1` SOUTHWEST AREA STUDY Study Area The Southwest Area includes land south of Melrose Avenue and generally west of Sunset Street. Since the Comprehensive Plan Update in 1983, construction of U.S. Highway 218 with Interchanges at Melrose Avenue and Highway 1 has been completed, Highway 1 West has been reconstructed as a four -lane limited access facility and Mormon Trek Boulevard has been realigned. Highway 218 isolates the western portion of the study area from existing j development east of this divided highway. Both residential and commercial uses have developed in the area; much of the study area west of Mormon Trek Boulevard, however, j remains in agricultural use. Comprehensive Plan The 1983 Comprehensive Plan Update envisions that, with the exception of platted portions of Hunter's Run Subdivision, residential development would be confined, in the short-range, to areas east of Highway 218 to promote efficient, compact and contiguous growth. Land west J of the highway is to remain, in the short-range, in agricultural use or, due to constraints in providing municipal sewer service to portions of the area, is to be developed at rural residential densities. These land use decisions are based upon the City's Interest in maximizing the efficiency with which municipal services are provided. — The Plan Update recommends annexing land, presently zoned commercial under county j — zoning, within the northern quadrant of the Intersection of highways 218 and 1 and zoning the land to allow commercial development. The objective of this recommendation is to focus commercial and industrial development in this location and to resist commercial development pressures at the Melrose Avenue Interchange with Highway 218. The Plan anticipates that land surrounding the Melrose Avenue interchange will develop for residential uses. While access to Highway 218 from Melrose Avenue and Highway 1 makes commercial development attractive at both interchanges, the Plan suggests the City may not be capable of supporting full development of commercial and industrial development at both locations. Proximity to the airport and to two main traffic facilities make residential development in the vicinity of the Highway 1 Interchange less desirable. These conditions, however, coupled with _ the availability of sewerable land for more Intensive land uses, make the northern quadrant of the Highway 1 and U.S. 218 interchange a logical location for commercial and industrial — development. The 1983,Plan Update also suggests that because land in the eastern quadrant of the highways 1 and 218 Interchange is sewerable, annexation of the eastern quadrant of the Interchange to "Dane's Road" and to existing development south of Highway 1, may be j desirable. In the long-range, this area may be suitable for industrial development at such time as sewer service is extended or the demand for industrial uses is felt. I 96 I The Plan Update identifies a portion of the Southwest Area, west of U.S. 218, which Is bordered on the north by Rohret Road and on the south by the corporate limits, where, as a result of topographic changes, the provision of municipal services was perceived to be expensive. Deannexation of all but a 300 -foot wide strip fronting Rohret Road is, therefore, encouraged in the 1983 Plan Update to permit control of development along Rohret Road while limiting what the Plan expects to be a cost prohibitive municipal service commitment to this area. i Issues 1. Sewer Service Availability. Extension of the Willow Creek Trunk Sewer to Chatham Oaks, the former Johnson County Care Facility, has increased development opportunities in the Southwest Area. The capacity of this trunk sewer continues to be restricted, however, by a 10 -inch segment of the trunk line which creates a bottleneck ! situation at the point where an 18 -inch portion of this trunk sewer line connects to the smaller diameter pipe. Consistent with the City's intent to maintain compact and I contiguous growth and to maximize efficiency in the provision of municipal services, no public commitment of funds to relieve this constraint is proposed in the short-range. As noted in the 1983 Update to the Comprehensive Plan, without upgrading the constraint caused by the 18-Inch/10-inch sewer line connection, sufficient capacity remains within the 10 -Inch line to permit development of sewerable land lying east of Highway 218 which is within the service area of the 10 -inch trunk sewer. Except for the commitment made to allow development of the Hunter's Run Subdivision, any additional development permitted west of Highway 218 will diminish the City's ability to service land east of the highway and adjacent to existing residential and commercial uses. Also affecting sewer service capacity to developable land east of U.S. 218 is the City Council's decision in February, 1988, to approve the request to rezone an 85 acre tract located west of U.S. 218 and immediately east of the corporate limits from RR -1, Rural Residential, and ID -RS, Interim Development Single -Family Residential, to RS -5, Low Density Single -Family Residential. Approval of this request was conditioned, however, on its consistency with the City's out -of -sequence development policy which is based on the City's Interest in maximizing the efficiency of municipal growth and development. While sewer service to portions of this 85 acre tract may have to be assisted by means of a lift station, It is expected that one lift station of sufficient capacity to serve the rezoned tract and surrounding rural residential zoned land would be used. if the lift station is capable of serving the area recommended for deannexation in the 1983 Plan Update, deannexation of this area would not be necessary. If development of portions of the Southwest Area proceeds prior to the development sequence recommended for the area, it is expected that all development costs will be borne exclusively by the developers of any land which is not in sequence with the City's growth management policy: This includes the costs of Improvements typical) subsidized by the City. If any further development west of U.S. 218 Is permitted 97 /09/ approval should, therefore, be conditioned upon the development's consistency with the adopted policy which allows out -of -sequence development. Insofar as development of land west of U.S. 218 may accelerate the need to upgrade the 18-inch/10-Inch sewer line connection, the extent to which that non-sequent development constrains development of land east of the highway must, therefore, be measured and the prorated cost of upgrading that connection assessed to the non-sequent development. Furthermore, proposed improvements to the City's wastewater treatment system do not include upgrading a restricted section of the Southwest Interceptor Sewer which is located on Highway 1 near the Sunset Street intersection and which serves the Southwest Study Area, Although 3,552 acres of undeveloped land lie within the major service area of this sewer, with a remaining capacity of 1,530 GPM, the development potential of this interceptor system is estimated to be 2.6 people/acre, significantly less than the development density permitted in the City's single-family residential neighborhoods. This Southwest Interceptor Sewer System constraint, coupled with the sewer restriction caused by the bottleneck situation of the 18-inch/10-inch sewer line connection, justify careful evaluation of future requests for subdivision approval west of Highway 218 as a result of the limited capacity available. 2. Traftways. In October, 1987, the Johnson County Council of Governments completed a traffic study of a portion of southwest Iowa City entitled The Southwest Iowa Citv Traffic Studv. The area evaluated in the study is bounded by Melrose Avenue on the north, Rohret Road on the south, Mormon Trek Boulevard on the east and Slothower Road on the west. The purpose of the study was to evaluate the existing street network's ability to handle existing levels of traffic and traffic generated by full development of the area studied in that report. The study concluded that the capacity of the arterial street network in southwest Iowa City is adequate for the existing level of traffic. In fact, the present capacity of the Melrose Avenue/Mormon Trek Boulevard Intersection is expected to be adequate with full development of the study area west of Mormon Trek Boulevard. Certain trafficway Improvements are anticipated, however, as development west of Highway 218 progresses. The study suggests that collector streets to serve land west of the highway should be provided. As the need for an arterial street between Melrose Avenue and Rohret Road becomes apparent, this study recommends using the existing alignment of Slothower Road from Melrose Avenue to the Southwest Estates Subdivision as a means of access to this area. Slgnalization of the Rohret Road/Mormon Trek Boulevard intersection as well as capacity Improvements to the Rohret Road approach of this Intersection are also contemplated with development of the traffic study area. A pedestrian walkway on Rohret Road over Highway 218 may also be desirable to link children and residents to schools, parks and other facilities east of the highway. 1 3. Schools. The study area is served by Horn and Roosevelt elementary schools. Ernest Horn Elementary School and Roosevelt School are approaching capacity. Full residential development of the Southwest Area as well as development In other areas are expected to challenge the capacities of existing schools in Iowa City. As the Southwest Area reaches full development, additional school facilities may be required. The undeveloped residential portion of the Southwest Area is approximately 700 acres in size of which about 500 acres will most likely develop for single-family residential use. Almost 200 acres of land, predominantly located in the southwestern portion of this study area, are topographically incapable of being served by the City's gravity Bow sewer system. Unless City sewer service via a lift station and other municipal utilities and services can be cost-effectively extended to these tracts, this land Is expected to develop for large lot, rural residential purposes. Based upon the number of lots within previously platted single-family residential subdivisions in the Southwest Area, 500 acres of undeveloped, single-family residential zoned land would generate about 1,660 lots. About 60 percent of existing single-family homes in the Southwest Area are three- bedroom units; 40 percent of the dwellings are four-bedroom units. When national school -aged children multipliers, which are based on housing unit size, are applied to the potential 1,660 new single-family dwelling units in the Southwest Area, it is projected that approximately 1,482 school -aged children would occupy these new single-family homes once the Southwest Area reached full development. Tracts that may develop for low density rural residential uses would also generate additional school -aged children. If capacity in the school system is reached city-wide, consideration will have to be given to accommodating children living within these new residential areas by renovating and/or expanding existing schools or constructing new facilities. 4. Parks/Open Space. For the portion of the study area east of Mormon Trek Boulevard, active and passive recreational facilities are provided on the grounds of Horn and Roosevelt schools and in Willow Creek and Villa parks. Recreational needs, to some extent, are also satisfied on the grounds of West High School, west of Mormon Trek Boulevard, As a result of the availability of these active and passive recreational resources, no new park facilities east of Mormon Trek are contemplated. As development progresses west of Mormon Trek Boulevard, however, additional parkland and open space will be required to serve new residents. Based upon criteria applied to undeveloped portions of the Southwest Area, the Neighborhood Open Space section of this Update contemplates that new facilities will be required to satisfy the open space needs of area residents. Two of the open space districts outlined In the Open Space Plan - West High and Hunter's Run - are located In the Southwest Study Area. Except for the southeast quadrant of the intersection of Highway 218 and Melrose Avenue, the West High Open Space District Includes that portion of the study area south of Melrose Avenue, west of Mormon Trek Boulevard and northeast of Highway 218. While the West High School site offers certain open space opportunities for future n ' I , residential development, the plan recommends that 5.58 acres of additional open space be developed to accommodate the residential population projected to occupy the West j High Open Space District once it is fully developed. The Hunter's Run Open Space District includes land within the corporate limits west of Highway 218. Future residential development within this district is expected to be I served by a sizeable park proposed north of and within existing development within the Hunter's Run Subdivision. 5. Proposed Residential Development Sequence. For purposes of devising a development sequence, the Southwest Area is generally divided into two areas by U.S. Highway 218. This division is based upon the extent of infrastructure improvements required and the degree of continuity to existing development. Until development east of the highway is complete, it is not cost-effective for the City to subsidize the j improvernmtpts required west of the highway, to extend municipal services to that area, and to encourage development at the City's margin. In the interest of compact and T contiguous growth, development of land west of U.S. Highway 218 will be discouraged w at least until such time as other developable land within the Southwest Area that requires less costly capital expenditures is developed. RECOMMENDATIONS � i 1. With the exception of the already platted Hunter's Run Subdivision, residential development should be confined to areas east of U.S, Highway 218 to promote efficient, compact and contiguous growth. Commercial and industrial development should proceed In a manner consistent with the land use recommendations of the 1983 Comprehensive Plan Update. 2. An area of land generally east of the Highway 218 and Highway 1 Interchange and west of "Dane's Road" and extending north to the city boundary line should be annexed to focus commercial and industrial development at this Interchange. 3. Commercial development pressure should be resisted at the Melrose Avenue Interchange with Highway 218. i= 4. No school sites need be designated in the study area at this time. With full development of the area, the need for additional facilities or some alternative is anticipated. j J 5. Coincident with development of the Southwest Area, additional parkland west of Mormon Trek Boulevard will be needed. i 100 . i /ti'/ I/ NORTHWEST AREA STUDY Study Area The Northwest study area is bound on the north and west by the City's corporate boundary, on the south by Melrose Avenue and on the east by the western boundary of the University of Iowa property. The Northwest Area remains largely undeveloped and in agricultural use. Comprehensive Plan The 1978 Comprehensive Plan envisioned the land included in the Northwest Study Area as developing for residential uses at a low density of one dwelling unit per acre, This area was not included in the development. sequence of the 1978 Comprehensive Plan or the 1983 Comprehensive Plan Update's sequence of development plan since the area could not be provided with sanitary sewer service except at considerable expense. Deannexation of the western portion of the area was also contemplated. Discussion of the Northwest Study Area in this Comprehensive Plan Update and its inclusion t in the development sequence is due to Iowa City's interest in a proposed office, research and development park in this quadrant of the City. Completion of U.S. Highway 218 has increased the Northwest Study Area's development potential for office research or research and development uses by providing visibility for the area from a major thoroughfare and by providing access to the interstate highway system. j Issues 1. Sewer Availability. The greatest constraint to the immediate development of the Northwest Area is the topography and its effect on the extension of sewer service. It Is for this reason that the area was excluded from even the long range development plans for the City in 1983. Given renewed Interest in the area for office, research and development uses consistent with the City's economic development goals, it is appro- priate to re-evaluate the issue of sewer availability and the relative benefits of development of this area. Of the approximately 1,100 acres in the Northwest Study Area, none are presently serviced by existing sewer lines. Historically, the extension of trunk lines is dependent on when development occurs and is funded, in large part, by the developer. Trunk lines extended Into this area will probably utilize the Hawkeye lift station, located west of Mormon Trek Boulevard on University property, to pump sewage from the Clear Creek watershed to the Willow Creek watershed, overcoming the topographic constraints to serving the area. The Hawkeye lift station is currently operating inefficiently because of the low volume of sewage flowing Into it. The lift station has enough reserve capacity to handle full development of the Northwest Study Area; however, development is constrained by the lack of capacity existing downstream from the lift station in the 101 1 ^ Southwest Interceptor sewer. i Currently, the most restrictive section of the Southwest Interceptor sewer is located at Highway 1 near the Sunset Street intersection. Remaining excess capacity is 1530 _ gallons per minute (GPM) in the restricted section. The development potential for the entire Southwest Interceptor System service area north and west of Highway #1, estimated to be 3,552 acres, is 2.6 people/acre, considerably less than the typical density of Iowa City's residential neighborhoods. Construction of the new Water Pollution Control Plant (WPCP) will not directly improve this development potential. The Southwest Interceptor sewer will continue to be served by the old sewage treatment plant until such time as the old plant nears capacity. At that time the Southwest i Interceptor will be upgraded and rerouted south of the airport and across the river to tie in with the new sewage plant. It is not anticipated that this will occur within the next 20 years. !.j Since the Southwest Interceptor sewer serves the Southwest Area and the Northwest Area, consideration is given to the relative cost of developing these areas with municipal sewer when determining the proper sequence of development. Because trunk lines _! exist in the Southwest Area and do not exist in the Northwest Area, development which depends upon municipal sewer should occur in the Southwest Area prior to its occurrence.in the Northwest Area. 2. Access and TroHlcways• U.S. Highway 216 runs northwest to southeast through the Northwest Study Area and can provide the type of access Important to large office/research parks. Melrose Avenue to the south and Highway 6 in Coralville to the north form the basis for a future network of collector and local streets serving land uses in the Northwest Study Area. However, currently the area lacks an interior street system. Camp Cardinal Road is the only existing interior roadway that future development could use as access to this area. In the future Camp Cardinal Road should serve as a secondary arterial street within the area carrying traffic from Highway 6 in Coralville through the Northwest Area to Melrose Avenue. Camp Cardinal Road and all other roads which some day will form the street ^I network for the Northwest Area will be extended as development occurs and will be primarily financed by the developers of the property. Melrose Avenue is only two lanes wide with no curbs from the Highway 216 Intersection east to West High School, where the road widens to four lanes. The Capital Improvement Program (CIP) of the City has Included widening Melrose Avenue to four lanes to better accommodate through -traffic. The "Melrose Avenue Capacity Analysis," '— completed In August 1987 by the Johnson County Council of Governments Transpor- tation Planning Division, addresses capacity issues on Melrose Avenue between '- University Heights and Byington Road. The study notes that development in the Northwest Area will potentially have an Impact on the Melrose Avenue corridor east of University Heights by generating pass -by traffic. Acknowledging that development of the Northwest Area within the 25 year time frame of the plan is speculative, the study states "If residential development of 600 units and 50% development of the Clear Creek ' 102 — research park occurs within a 25 year period, then oversaturated traffic conditions may result even with four lane operation." With full development of the Northwest Area, the traffic anticipated on Melrose Avenue will increase to the extent that additional capital improvements, beyond widening the road to four lanes, may be necessary, or — management of traffic demand may need to be employed. 3. Land Uses. The Northwest Study Area is largely zoned either Interim Development - Office Research Park (ID -ORP) or Interim Development - Residential Single Family (ID- ,..I RS) at this time. Interim Development Zoning is intended to provide for areas of managed growth in which agriculture and other non -urban uses of land may continue until such time as the City is able to provide municipal services to support urban development. Interim development zones are periodically re-evaluated to establish whether the policy for these areas is still appropriate given the current development potential of the area. iIowa City's policy is to encourage growth in a compact and contiguous manner to foster a cost effective approach to service extensions. Development in the Northwest Study W Area will require service extensions far removed from existing serviced areas which will i^ raise the per capita cost of City supplied services. Any development policies which encourage development in the Northwest Area should recognize these costs and assure their most equitable distribution between private developers and the taxpayers of Iowa City. a. Office Research and Development Centers. With completion of U.S. Highway -. 218, the Northwest Area is a viable location for office, research and development centers. The campus -like environment, characteristic of these types of development, is easily obtainable given the rolling hills and substantial timber present. Highway 218 provides ready access to other major traffic corridors, I- 80 and 1-380 to the north and Highway 1 to the south. Hotels/motels are lacking _ in this area at this time; however, existing hotels/motels are within a three mile radius. Accessibility to both the Iowa City and Cedar Rapids airports is especially convenient from this part of the city. _ Since City services have not been extended to this area, substantial service Improvements will be required before development can occur with municipal services. The decision of the City in the previous Comprehensive Plan Update was to defer development of this area to beyond the long-range development objectives of the City. In essence, this policy meant that the City did not anticipate expending any capital in this area and that there was no public Interest In either facilitating or recognizing development of the area. Given renewed private sector interest in this area for office, research and development center uses, this pian recognizes the potential future development of this area for office, research and development uses. Due to the potentially high cost of Infrastructure Improvements, it is not anticipated that this development will proceed in the near future. Private sector Initiative or a public/private partnership could, however, change this time frame, I _ 103 . /09/ C. The area currently zoned ID -ORP reflects property lines and the area of Interest for development; however, reconfiguring the northerly boundary as illustrated in Figure 2 may be appropriate. The cross -hatched area slopes northerly while the remainder of the ID -ORP area slopes southerly. To sewer this northerly area would require the use of a lift station to pump the sewage over the ridge to a southerly trunk line, or the extension of two separate trunk lines to service the area by gravity flow through the Hawkeye lift station. Since the ridge line also serves as an effective topographical distinction between land uses, an extension of the residential land use classification to the south is appropriate. Residential. Development of the area currently zoned ID -RS would entail the extension of sewer service via sewer lines extended west and southwest from the Hawkeye lift station. These sewer lines would have to traverse a significant distance, raising the cost for each dwelling unit constructed. This acts as a disincentive to residential development. Given the lack of existing utilities and the cost of extending sewer service to this area, development of the currently zoned ID -RS area at urban densities should not take place in the next 15 year period, unless services are extended to the area for non-residential purposes. The topography of the Northwest Study Area is generally hilly with tree cover retained in many parts of the area, particularly along drainageways and on the steeper slopes of the hills. These are natural amenities which should be preserved and which also make the area attractive for certain sectors of the residential housing market. Given the right combination of property ownership, market economy, the natural amenities and the difficulty of extending municipal sewer service, this area may be appropriate for large lot development on septic systems or private treatment facilities, This portion of the Northwest Area can provide a residential development option in the City which is currently available primarily in the unincorporated parts of the County and may bring some of that development back Into the incorporated area. For this to happen, modifications In development regulations will need to be made to make the economic benefit of development in the City at lead equal to that of development in the County. Commercial. The land uses around the Highway 218/Melrose Avenue interchange were addressed in the 1983 Comprehensive Plan Update in the Southwest Study Area. At that time, residential development was favored for the area surrounding the Interchange In order to direct commercial development to the Highway 1 interchange with Highway 218. This policy was based on the available land at the Highway 1 Interchange that was currently sewerable and the desirability of concentrating commercial and industrial uses along Highway 1. 104 Northwest Area Figure 2 RRl scut: 600 FT. O 183M. ID -RS ID -ORP Proposed desi for Residential ID -RS The previous policy is still valid. Sewer availability has not changed appreciably and the Highway 1 Interchange is, in fact, developing in a manner consistent with this policy. This southerly interchange is a better location for commercial uses given the existing commercial nature of the interchange and the Highway 1 corridor and given the intersection of three major traffic corridors - Highway 1, Mormon Trek Boulevard, and Highway 218. Pressure to develop the Melrose _ Avenue interchange for commercial use will probably not occur until develop- ment begins in the Northwest Study Area, particularly the office/research use. Full development of the currently zoned ID -ORP area could precipitate demand for a hotel/motel development at the Melrose interchange. This use is consistent however with the office, research and development center uses envisioned in this area and is permitted under the zoning classification for such centers. No change in policy is necessary, therefore, and changes inconsistent with this �I policy should be resisted to maintain the Melrose Avenue interchange as an + entrance to the office/research and residential area of west Iowa City. ' 4. Schools. The Northwest Area is not currently included in a defined school area M� boundary. Schools serving areas in proximity to the Northwest Area are Kirkwood, Coralville Central, and Horace Mann. Kirkwood and Coralville Central are close to or r" at capacity; Horace Mann is well below capacity. Attendance at any of these schools f would require school boundary changes to Include the students from this area. With full development of that portion of the Northwest Area presently zoned for _ residential use, approximately 450 acres may potentially generate 670 school -aged children. This number of new children would require, at some point in the development of the area, consideration of a new school facility or reconfiguration of current school service area boundaries. S. Parks. The Open Space Plan distinguishes one district for the Northwest Area - the Clear Creek district. A need for 17 acres of open space is projected. If rural residential development takes place on large lots as outlined above, the need for 17 acres of open space should be re-evaluated and possibly diminished. Development Sequence A large part of the Northwest Area Is designated for office research and development center use. Consistent with the rest of the plan, areas designated for non-residential use are not Included in the development sequence. The office, research and development center land may develop at any time depending upon the private sector's willingness to do so and/or the decision of the public sector to subsidize or encourage that development, At this time no public commitment has been made to extend services or Infrastructure for development of this area, 106 AW The areas shown for future residential development fall into the last phase of the development sequence of the plan due to the extensive infrastructure and service needs. Development may occur earlier if private systems are used, or in accordance with the City's out -of -sequence development policy in which the developer assumes the full burden of the cost of immediate service extensions. RECOMMENDATIONS 1. Office, research and development centers should be Indicated as the eventual land use for the long-range development of that area currently zoned ID -ORP as amended accordingly: The northern border of the ID -ORP zone should be redrawn to coincide with the location of the ridge line running through this area. The ridge line serves as an effective topographical distinction between office/research and residential uses to the north. 2. Residential development at urban densities north of Melrose Avenue and east of Freeway 218 should not take place in the next 15 years. Development for urban residential uses should be shown for the long-range. If rural density residential development is to be fostered, the City will need to re-evaluate its development standards to make such development economically desirable. 3. Commercial development should be restricted to the Highway 1 Interchange with Freeway 218, The Melrose Avenue Interchange should be protected as an entrance to the office/research and residential areas of west Iowa City. 4. No school sites need be designated in the study area, since full residential development at urban densities is not anticipated in the next 20 years. 5. Seventeen acres of open space are projected as needed for urban density residential development in this area. If residential development takes place at a rural density on large lots, the necessity of that much open space should be re-evaluated. 107 I I J L j PENINSULA AREA STUDY Study Area The Peninsula Area is bound on the north by Interstate 60, on the east by North Dubuque i Street, and on the south and west by the Iowa River. These natural and manmade barriers Isolate the Peninsula Area from other development areas of the city. The Peninsula is approximately 530 acres in area and is largely undeveloped and in agricultural use. A limited amount of residential use is concentrated in the eastern portion of the study area. Single-family residential dwellings are located north of Foster Road and immediately west of North Dubuque Street on Laura Drive and Knoliwood Lane. Other single-family dwellings 1 are located along the Iowa River south of Taft Speedway. A limited number of mobile homes and multi -family residential uses are generally located west of Laura Drive. The Elks Club, with recreational facilities and a golf course, occupies approximately 70 acres in the center of the Peninsula. Most of the land adjacent to the Iowa River is in the floodplain. Environmental limitations and the tack of sewer service have prevented development in this area to date. An assessment of the development potential of the Peninsula and appropriate land uses for this area will be addressed in this study. �i Comprehensive Plan The 1983 Comprehensive Plan Update envisions the Peninsula developing primarily for low- density residentialuses (2-8 dwelling units per acre) with medium density residential uses (8- 16 dwelling units per acre) restricted to the eastern edge of the study area. While the Plan Update recommends residential land uses for the long-range development of the entire Peninsula, the Plan also suggests that, when fully developed, northern Iowa City, Including the Peninsula Area, could support additional commercial activity north of Brown Street. Although the Plan does not designate a particular site on or near the Peninsula for neighborhood commercial development, the Plan does recognize that, given the development potential of the Peninsula Area, a commercial center west of Prairie du Chien Road, in the Dubuque Street/Peninsula area, would provide convenient and accessible services to future residents of the area. Issues 1. Sewer Availability. Presently, approximately 60 of the 530 acres within the Peninsula are sewerable without major capital Improvements. These sewerable areas are located adjacent to existing development in the Peninsula and would, therefore, permit compact and contiguous growth. Capacity for most of this developable area Is unconstrained as a 36 -inch line extending Into the Peninsula Area ties in directly to the 36 -inch River Corridor Sewer. 108 AM i Construction of a sewer extension to serve the remainder of the Peninsula is not, however, Included in the schedule of proposed improvements to the city's wastewater system and no public commitment to extend this service to permit development of the remainder of the Peninsula is anticipated In the short-range. Full development of the Peninsula can occur following extension of a trunk line westward from its present terminus near the Taft Speedway/Calibria Court Intersection. 2. Environmental Considerations. A significant amount of undisturbed natural scenic features exist within the Peninsula Area. This is due to the fact that much of the Peninsula is bound by the Iowa River, the city's most prominent natural resource, and that much of the study area remains undeveloped. Peninsula land adjacent to the river is wooded and susceptible to Inundation by flood waters. These "bottomland" woods are generally found in floodplain areas, a habitat characterized by poor drainage with moisture conditions ranging from total inundation to very dry periods during the summer. These characteristics pose severe limitations to urban development. To protect life and property, development within flood prone areas is limited by the requirements of the City's Floodplain Regulations. A major ridge, approximately 80'-100' above the flow of the river is located in the heart of the Peninsula Area. This portion of the Peninsula, currently undeveloped or in agricultural use, is the area best suited for development as It has adequate drainage and few erosion hazards. Only slight to moderate urban development limitations characterize this part of the Peninsula. Between the Peninsula ridge area and wooded bottomland and extending north of Foster Road are steep, wooded ravines that function as drainage channels that discharge surface runoff directly into the Iowa River. Slopes of over 18 percent occur in this area. Construction difficulties and erosion hazards are two potential problems associated with steep slopes. Severe development limitations exist on this land. The natural features of the Peninsula Area - the floodplain, the bottomland and upland woods and the steep slopes - are aesthetically pleasing and are natural means by which the community is protected. Rivers and creeks are the natural drainage channels of the j city. The Iowa River floodway and floodplain are the natural corridors that carry waters that flow across the impervious surfaces of developed areas, The water absorption and filtering abilities of the vegetative cover on steep slopes and on the bottomlands aid in maintaining water quality and in reducing the risks of flooding and erosion. It Is the policy of the City to preserve and protect these environmentally sensitive areas. Any development which takes place in this study area should, therefore, be controlled to ensure that the environment is protected. The City's Environmental Policies also encourage the preservation and enhancement of the city's entranceways. The eastern edge of the Peninsula Area is a prominent part of the North Dubuque Street entrance to the community. Since development of this portion of the Peninsula will provide one of the first visual Impressions of the community, it should proceed in a careful manner. I 3. Access and 7raNlcways. As the Peninsula develops, Foster Road will bestserve the area's needs as a collector street, functioning as the Peninsula's main trafficway and linking the area to Dubuque Street. The increase in traffic at the intersection of Dubuque Street and Foster Road, which will occur once development of the Peninsula proceeds, will most likely require signalization of this intersection. The timing of installation of a signal will be determined in part by the density of development in the area and the rate at which development occurs. The unique physical characteristics of the Peninsula Area limit secondary access alternatives for this study area. An alternative to Dubuque Street to access interior and portions of the western p Peninsula Area is to bridge the Iowa River. This alternative, however, is politically infeasible because it would be cost prohibitive, disruptive to existing development on the opposite side of the river and may impair the sensitive resources and natural qualities of the Peninsula. Extending Taft Speedway westerly into the Interior portion of the Peninsula offers another secondary access option for this part of the study area. I Secondary access to the eastern part of the Peninsula is provided via Taft Speedway. Construction of a north -south oriented roadway in the vicinity of Calibria Court would facilitate secondary access to the northern parts of the Peninsula. 4. Land Uses a. Residential. In the long range, the Peninsula Area is expected to develop for _ residential purposes. Much of the Peninsula Area is zoned Interim Development Single -Family Residential (ID -RS) at this time. The Interim Development zone is Intended to provide for areas of managed growth in which agricultural and other non -urban uses of land may continue until such time as the City is able to provide municipal services and urban development can take place. Interim development zones are periodically re-evaluated to determine whether the land use policies for these areas are still appropriate in light of the development potential of the areas. Development of the part of the Peninsula currently zoned ID -RS requires ! extension of the trunk sewer that presently terminates near the Taft Speed- way/Calibria Court intersection westward along the perimeter of the Peninsula as well as extension of municipal water service. No public commitment to extend these services to this portion of the Peninsula is anticipated prior to development of the sewered, eastern portion of the Peninsula Area. The 1983 Comprehensive Plan Update envisions a higher density of residential development for the eastern part of the Peninsula than for the rest of the study iarea. Low to medium density multi -family residential zoning classifications shown In eastern portions of the Peninsula identify the locations of existing multi -family residential developments in the study area. Sizeable undeveloped tracts of land which are almost entirely in the floodplain and located west of Dubuque Street, I between Foster Road and the river, are currently zoned for medium density single-family residential development. The physical characteristics of this land, however, make it better suited for low density single-family residential development. The environmentally sensitive nature of these undeveloped tracts, coupled with their visibility from a major entryway into the community, justify encouraging future development that adapts to and is harmonious with the natural features of this part of the city. A low density single-family residential zoning classification on this tract would assure that the environmental fragility of this tract would be given more consideration and that the purposes of the City's Environmental Policies would be better fostered. If residential development of the Peninsula Area proceeded in a conventionally r platted manner, however, even low density single-family residential development -+ could have undesirable environmental consequences. Loss of vegetation, Increased runoff and erosion, Increased flooding and deteriorated water quality i may be likely consequences of conventional development on the Peninsula, Although a density range of 2-8 dwelling units per acre may be the most appropriate land use density designation for the Peninsula Area, larger lot sizes 1 in some locations may be necessary to provide home sites that are sensitive to the unique characteristics on the Peninsula environment. Larger lot development on the Peninsula could not only protect the natural amenities of the area but may provide a residential development option in the city which is currently available primarily in the unincorporated parts of the county. To make large lot development in the city economically competitive with residential development permitted in the county, however, modifications to development regulations will _ need to be made to make the economic benefit of development in the city equal to that of development in the county. The Peninsula Area is also well suited for planned development housing (PDH) which can allow flexibility in the placement and clustering of buildings, the provision of streets, and the use of open space. A planned development can j J promote einciency by minimizing the network of utilities and streets required in an area while allowing development to occur in a manner sensitive to the area's natural features. With this zoning technique, residential development can be concentrated in those portions of the Peninsula more physically suited to urban development while environmentally fragile land can remain undisturbed. As a -, means of implementing the City's Environmental Policies within the Peninsula Area, the City may consider imposing planned development zoning on designated areas with standards that produce developments sensitive to the existing natural features of those areas. Use of this mechanism will require re- evaluation of the planned development overlay zone. 0 b. Commercial. The 1983 Comprehensive Plan Update recommends residential land _ uses for the long-range development of the entire Peninsula. However, the Plan suggests that full development of northern Iowa City, including the Peninsula Area, could support additional commercial activity north of Brown Street, between the Iowa River and North Dodge Street/Highway 1. Although the Plan does not designate a particular site on or near the Peninsula for neighborhood commercial development, it does note that to be easily accessible to Peninsula Area _ residents and to provide a competitive balance to existing commercial development, a commercial center should be located west of Prairie du Chien Road. Existing features of the Peninsula do not make the Peninsula Area a suitable l location for a neighborhood commercial center. The environmental character- istics of the Peninsula are better suited for uses that reserve a significant amount of pervious surfaces. Commercial developments typically demand large areas of pavement which would also alter the wooded and open nature of the northern entrance to the city. These environmental considerations make low density residential development a more appropriate land use choice for the Peninsula Area. 5. Schools. The study area is served by Horace Mann Elementary School which is f presently at about 65 percent of its maximum capacity. However, full development of the Peninsula Area may potentially generate 1,270 school -aged children. At some point In the development of the Peninsula, consideration will have to be given to a new w school facility or reconfiguration of current school service area boundaries to accommodate these children. 6. Parka/Open Space. In the short-range, Terrill Mill Park and City Park can serve the recreation needs of Peninsula residents; in the long-range, however, additional, more accessible neighborhood -oriented open space will be needed to serve the Peninsula population. The environmentally and ecologically fragile areas of the Peninsula, particularly adjacent to the Iowa River, may satisfy the open space requirements of this study area, The Peninsula's riverfront could offer passive recreational opportunities. The City will continue to encourage greenbelts along the Iowa River to preserve and protect the natural features of the riverfront. The open space recommendations of the Iowa River Corridor Studv, prepared in 1975 by Stanley Consultants, Inc., which do not conflict with the open space and environmental recommendations for the Peninsula Area as identified in this plan update, remain ongoing open space development objectives for this study area, 7. Proposed Residential Development Sequence. Recognizing varying development limitations, the Peninsula Area is divided Into two subareas for purposes of devising a development sequence. The division is based upon the extent of infrastructure Improvements required and the degree of contiguity to existing development. Depending upon the overall rate of growth in the city, the subarea identified as the East Peninsula in the development sequence section of this Update is expected to develop 112 /09/ ■ s, in the short-range within 5-10 years. Because public participation in the extension of municipal services to the balance of the Peninsula Area is not anticipated in the short- range, the rest of the Peninsula should develop in later phases of growth. RECOMMENDATIONS 1. Development within the Peninsula Area should be considerate of the environmentally sensitive features of the area. 2. Foster Road should adequately serve the Peninsula Area as a collector street and as the major traHicway linking the Peninsula to Dubuque Street, 3. The existing undeveloped portion of the eastern part of the Peninsula, currently zoned RS -8, should develop exclusively for low density single-family residential uses. The balance of the Peninsula should also develop for low density single-family residential purposes. Commercial development on the Peninsula is not recommended. 4. Given the unique natural features of Peninsula Area land, consideration should be given to imposing large lot and/or planned development zoning on designated areas to produce developments sensitive to these natural characteristics. 5. No school sites need be designated in the study area at this time. With full development of the area, the need for additional facilities or some alternative should be anticipated. 6. With full development of the Peninsula Area, additional neighborhood open space will be needed to serve the Peninsula population. Passive recreation opportunities offered along the Iowa River could serve these neighborhood -oriented recreation needs. 7. Preservation of greenbelts along the Iowa River should be encouraged and the open space recommendations of the Stanley Consultants' Iowa River Corridor Study which do not conflict with the open space and environmental recommendations for the Peninsula Area should continue to be the open space development objectives of the study area. 113 r; . I( NORTH AREA STUDY MENNEN Study Area The North Area is a particularly attractive part of Iowa City marked by wooded ravines, pastureland, and steep to gentle slopes. It is unique in that it has rural features and is close to the business and academic centers of Iowa City. The area is bound by Brown Street and Highway 1 to the south and east, 1-80 to the north, and Dubuque Street to the west. The location and nature of these roads effectively limit the transition between surrounding land uses, outside the study area, and those within the study area itself. Current uses in the area Include agriculture in the northeastern portion between 1.80 and Highway 1, highway commercial along parts of Highway 1 to Prairie du Chien Road, and residential uses, that are predominately single-family, along the roadways of Prairie du Chien, IQmball Road, and Whiting Avenue. At least half of the land in the area is vacant or used for agricultural purposes. iApproximately 198 acres of land is available for development west of Prairie du Chien Road and about 178 acres remain east of Prairie du Chien. Comprehensive Plan The 1983 Comprehensive Plan addressed two issues in the North Area - sewer capacity and ` access to "interior" undeveloped acreage. Since these issues are still applicable to the North Area, the discussion from the 1983 Plan is carried forward and expanded. _ I The land uses outlined in the 1983 Plan were primarily single-family residential throughout the study area with a cluster of high-density, single-family development projected between the extension of Foster Road and 1-80, west of Prairie du Chien. An existing neighborhood commercial use was delineated on North Dodge Street and it was recognized that, at some point, a neighborhood commercial area could be considered on the west side of the study area to serve the Peninsula, Issues Since the terrain of the North Area Is very hilly with a number of sharp ravines, development has occurred on the crests of the hills and the plateaus overlooking the ravines. The remaining developable land is to a large extent wooded and sloping, with access constrained by existing development and Interstate 80. The Issues having the greatest effect on development in this section of the city are the distribution of municipal sewer service between the area to the west and the area to the east of Prairie du Chien and the provision of access to "Interior" portions of the study area. 114 1. Municipal Sewer Service. The 198 acres west of Prairie du Chien Road are within the immediate watershed of the Iowa River; 74 acres can be serviced directly by the River Corridor Trunk and the remaining 124 acres must flow through the existing Bjaysville Lane sewer which empties into the River Corridor Trunk. Of the 178 acres east of Prairie du Chien, 119 acres are in the Rapid Creek watershed that drains north, beyond the Iowa City corporate limits. In order to service this eastern area, a lift station is required to bring the flowage Into the serviceable watershed to the west. To do so, however, decreases the already constrained capacity in the Bjaysville Lane line available for the development of land to the west of Prairie du Chien. Programmed improvements to the wastewater system will not alleviate this constraint. At present, the Bjaysville Lane sewer surcharges in wet -weather conditions. In order to adequately serve even the 124 acres west of Prairie du Chien at a density of 12 people/acre, this sewer line should be upgraded to 24 Inches. To accommodate j development east of Prairie du Chien, a lift station will be required to carry the effluent w to a watershed served. Since the watershed which the Bjaysville Lane line serves is _ the most practical for serving this easterly area, a re-evaluation of the appropriate size of the upgraded line will be necessary when development is proposed on the 119 acres east of Prairie du Chien. J2. TraHlcways. The topography of the North Area - the wooded ravines, numerous drainageways, and steep slopes - has acted as a natural deterrent to the rapid development of this entire section of the city. For development of this area to occur, access to the three main developable sections will be necessary. Foster Road is proposed as a collector between Dubuque Street and Prairie du Chien, with a jog before a road continues east from Prairie du Chien to Old Dubuque Road. Since sewer capacity is available to the west of Prairie du Chien without the use of a lift station, development in that area is encouraged to occur prior to development to the east. Actual development and construction of the road is at the Impetus of Individual property owners or developers. The City has chosen to facilitate development in the area by making land available for the necessary access to the main thoroughfares of Dubuque Street and Prairie du Chien along the preferred "Foster Road" alignment. Since Foster Road may at some time be continued to the east, it is recommended that driveway access be limited to the extent possible. Such limited access will allow for upgrading of the street in the future if usage demands and may encourage the development of clustered housing in this area marked by rough terrain and attractive wooded slopes. _ Access to the portion of the North Area east of Prairie du Chien Road is provided in part by the streets which are platted in the Oakes Additions. Further access may - extend off one of these roads to the north and loop back to Dubuque Road to the east, eliminating any connection with Prairie du Chien, thus keeping traffic flows within the developed area confined to predominately local traffic. I 115 ;.i J LJ Access to that area defined by Kmball Road, Whiting Avenue, and Dubuque Street could potentially come from any one of these streets. The access from Dubuque Street is problematic in that the most suitable road site conflicts with the parking lot for University housing at the Mayflower. The most feasible access points appear to be off of Kimball Road or a subdivision In the area (Nottingham Place, based one the inadequacy over, recent lf of argues against Whiting Avenue and Kmball Road as viable alternatives. Since Whiting Avenue flows Into Ridge Road, even upgrading Whiting Avenue would not resolve the inadequacy of the street system unless the geometrics of Ridge Road were changed. IQmball Road seems to offer the only possible means of access and will require improvement to adequately serve this area. If the City wishes to foster development in this area, use of the City's power to condemn land for the provision of secondary access, as outlined in the Transportation Section of this Plan, may be appropriate provided particular consideration is given to the environmental features of this area. 3. Neighborhood Commercial Area. A neighborhood commercial area has been suggested in past plans for a location somewhere along the Dubuque Street corridor. Full development of the Peninsula, the North Area, and further development in the County may create demand for such an area in the future. Given existing development and the lack of a site with the appropriate topography and access, no commercial site Is designated on the Dubuque Street corridor in the city. 4. Schools. Shimek, the elementary school which serves the North Area is currently over capacity. Using a 60/40 ratio of three-bedroom to four-bedroom units and national multipliers for the generation of school children, on the 376 acres of developable land In all of the North Area, there is a potential for approximately 559 additional school age children, Since full development of this area is not anticipated within the next ten years, no new facilities should be required within this timeframe. 5. Parkland/Open Space. The Open Space Plan delineates two districts in the North Area the Mayflower/Shimek district and the Dubuque Road district. Based on full development of the area, the Mayflower/Shimek district, which is essentially all of the area west of Prairie du Chien and north of I(imball Road, requires 11.14 acres of additional open space. The Dubuque Road district, which is east of Prairie du Chien, has a deficit of 3.8 acres. 6. Environmental Issues, This part of the city Is unique in that the natural features of the land are particularly scenic and attractive, When approving development proposals here, the City should be especially cognizant of these features and encourage through the use of planned developments and with amendments to the subdivision regulations, development which effectively preserves the natural features. 116 _ Development Sequence Due to the need for sewer system improvements, adequate access roads, school facilities and open space, both portions of the North Area east and west of Prairie du Chien are slated for development in Phase II of the development sequence. The area west of Prairie du Chien _i is favored for development first based on the greater magnitude of improvements required to the east. The area defined by Whiting Avenue and Kimball Road is slated for development in ,ji the first phase of growth. J RECOMMENDATIONS 'i 1. As soon as possible, the sewer serving the North Area should be upgraded to 24 - inches. Construction of this line should terminate at the city limits. Density designations in this area should be determined within the context of the capacity available in the 24 -inch line and the necessity to provide for future development in contiguous areas. 2. Development east of Prairie du Chien, beyond that already platted, should be encouraged only if the sewer line to the west is upgraded and the proposed lift station is constructed. Otherwise, development in the remaining area should await completion of a gravity flow system in the appropriate watershed, 3. Development in the western part of the North Area between Whiting Avenue and 1-80 should continue to be encouraged with the active participation of the City in facilitating construction of an access road, through the acquisition of land at the Dubuque Street J and Prairie du Chien intersections of the proposed road. 4. No neighborhood commercial area should be designated in the North Area. S. No new school sites are recommended at this time. 6. Parkland/open space allocations should follow the Open Space Plan. Given the unique natural features of the land In this area, efforts should be made to encourage cluster development and the preservation of wooded spaces. J I '� rVilm I■■ . P' �i ��j 4 � _ I INNER CITY AREA STUDY i_ Study Area The Inner City Area consists of much of the original town of Iowa City, from Brown Street to the Iowa Interstate Railroad and from the Iowa River to Summit Street, Muscatine Avenue and i.., Hickory Hill Park. The Central Business District (CBD) and the University are excluded from the area. The area is fully developed and is characterized by a range of residential densities I from old single-family neighborhoods to newer multi -family dwellings. Commercial uses are also found in the Inner City and are located primarily along Gilbert and Market streets. [ Because of the diversity of uses in this area, it is helpful when evaluating the Inner City to w break it up into subareas: the North Side residential area, the area surrounding and including Mercy Hospital, the College Hill residential area, the high-density residential and commercial area south of Court Street and west of Gilbert Street, and the residential area east of Gilbert Street and south of Burlington Street. Unlike the other study areas Included in this Plan, the land use decisions in the Inner City usually pertain to redevelopment and changes in land uses rather than the Improvement of undeveloped land. Therefore, the issues which arise in formulating a policy for this area are different. The preservation of housing stock, parking, and the compatibility of land uses have greater importance than does the provision of municipal services. In the discussion which follows, each of the subareas will be addressed in terms of the applicable issues either through a presentation of what has been done in an area, a policy statement, or a proposal of a future study. Comprehensive Plan Since 1978, the development policy for the Inner Ci has consistent) been to encourage the City Y 9 j establishment of commercial service businesses around the CBD and appropriate densities of ._ residential development in areas peripheral to the downtown and its service area. High density residential development close to downtown supports retail and service establishments — and adds to the vitality of downtown. Medlum-density residential uses provide a transition between multi -family and single family development and allow for the preservation of existing buildings, The 1978 Plan designated high-density residential development north and south of downtown and projected medium density development east of downtown. An area around Mercy Hospital was outlined for commercial office development. These concepts were reiterated in the 1983 Update. The preservation of existing housing stock and neighborhoods j were also goals of the 1978 Pian and the 1983 Update. These policies were Implemented in the North Side downzoning, the comprehensive rezoning of the City In 1983, the College Hill downzoning, zoning a commercial office area around Mercy Hospital, and continued zoning of areas south of the downtown for high-density residential development. An historic preservation ordinance enabling the designation of historic districts was also adopted and two historic districts were formed - Summit Street and Woodlawn. 118 AM These actions addressed a number of concerns about the Inner City area as a whole: the destruction of existing housing stock for high-density residential development particularly in the College Hill area, the preservation of historic neighborhoods and neighborhoods in general, encouraging residential development near the downtown to support downtown businesses, and the need for doctors' offices near Mercy Hospital. The extent to which these actions were successful In implementing the goals of the City varied, as explained In the following discussion. I — Issues Because the Inner City is developed, the issues dealt with in this area will differ from other area ^ studies. The Infrastructure - streets, sewer, and water are in place and the timing of any I. redevelopment is assumed to be unconstrained; the development sequence applied to other areas will not apply to the Inner City. The issues which do prevail are those which are associated with existing development - the maintenance of existing neighborhoods and existing I housing stock, the expansion of commercial development into residential neighborhoods at zone boundaries, on -street parking congestion, and the difficulty of redevelopment on smaller lots. 1. North Side Residential Area. The North Side comprises the old "Goosetown area from Reno Street west to Dodge Street, the near north side from Jefferson Street to Brown _ Street, and the residential area along Dubuque and Clinton Streets. The North Side contains some of Iowa City's oldest neighborhoods with housing stock ranging in age from the mid -19th century to dwellings constructed In the 1940s and 50s. In the 1970s, these neighborhoods were threatened by demolition and the construction of high density multi -family structures. The allowable density of the area was reduced by downzoning, ceasing the Incentive to replace older dwellings with new multiple struc- tures. Many of the larger older homes had been converted to apartments or rooming — houses. This movement also has been inhibited by downzoning and off-street parking requirements. In an effort to assure the preservation of many of the older historic structures in the North Side, the Historic Preservation Commission proposed the designation of a North J Side Residential Historic District in 1986. This proposal failed due to the size of the proposed district and the controversy generated amongst property owners in the proposed district. The goal of the district designation, as expressed by Its proponents, was two -fold: to preserve historic buildings and to maintain the integrity of the older residential neighborhoods. Based on the goals for the North Side residential area of maintaining existing housing — stock, protecting and enhancing existing neighborhoods, and preserving historic structures, the City should Investigate other methods In addition to historic district designation to attain these goals. Such methods should Include Increased local participation In rental and owner -occupied housing rehabilitation through loan and grant programs; the use of local tax Incentives to encourage Investment in neighborhoods; the active nomination of buildings for the National Register of Historic Places; continued efforts to designate historic districts of a more limited size than that proposed earlier; 119 A9 education of the public of the benefits of historic preservation; and the creation of neighborhood planning areas to foster grass roots identification of neighborhood problems and solutions. Along zone boundaries and high volume traffic corridors where existing older structures are threatened, the City may wish to consider selecting areas where it would be appropriate to permit limited commercial usage, such as professional offices, to enable buildings to be economically used and therefore saved. The appearance or sense of residential place would not then be lost even though a land use change would occur. The methods noted above, although Incorporated in a discussion of the North Side, may be applicable in other areas of the Inner City also. 2. Mercy HoapMal-Commercial/Office Area. The 1978 and 1983 Comprehensive Plans designated a 51/z block area, including Mercy Hospital, for commercial use. The Central Junior High School site and play field were denoted as public/semi-public. Upon sale of these sites to Mercy Hospital and Pediatric Associates respectively, these sites were zoned commercial office (CO -1) to coincide with their Intended use and, in the case of the Central Junior High site, in conformance with the zoning around it; the play field site was rezoned at the request of the buyer. The commercial designation in the 5Ys block area was intended to provide an opportunity for the conversion of housing on Bloomington, Van Buren and Johnson Streets to offices, primarily for physicians. Through conversions and the preservation of existing buildings, it was felt that not only would an option for the location of doctors' offices near the hospital be provided, but the residential character of the area would be preserved and the North Side neighborhood would be buffered from commercial expansion. The boundaries of the commercial office area were determined by existing uses, by the use of alleyways as good lines of transition from one use to another, by the likelihood of conversion given the existing use, and by the intended direction of the hospital's future expansion. Only two conversions have actually taken place since the option of commercial offices was made possible. One conversion required an exception to make a single doctor's office fit on one lot; in the other instance, additional land was required to support one doctor's practice. The apparent problems with conversions, as indicated by members of the medical profession, are 1) the size of building and lot needed to support a typical practice, 2) the difficulty and expense of assembling land to obtain the appropriately sized lot, 3) the cost of meeting building code requirements for medical offices, 4) the practical problems with using second story space In older houses for doctors' offices, and 5) the difficulty of providing adequate parking on residential -sized lots. Such conversions do not appear to be a practical means of providing medical office space near the hospital and of preserving existing buildings. There still exists, however, an apparent need for medical offices in proximity to Mercy Hospital, The hospital is contemplating construction of a 60,000 square foot facility on Centre Market, an existing parking lot south of the hospital. This structure will accommodate some private medical offices as well as house hospital facilities. A need for land for medical offices is perceived by the hospital as well as by other members of the medical community, To accommodate this need, this Plan retains the commercial WZ4] office designation on the north side of Bloomington Street and extends it one lot east on Jefferson Street to Incorporate a vacant lot and allow for limited office expansion on Jefferson Street. 3. College Hill Park Area. The College Hill Park area was the subject of a downzoning action in 1982. This area Includes much of the residential area east of Gilbert Street and south of Burlington Street. The rezoning action was instigated by residents who were concerned about the extensive demolition of older housing stock on Van Buren and Johnson Streets and the construction of multi -family structures. The area had been zoned for high-density multi -family dwellings; the rezoning included a number of categories from low -to medium multi -family densities. These areas have stabilized since 1982 and continue to provide a variety of residential options in relatively close proximity to the downtown. 4. Commerclal/Residential - West of Gilbert Street. The part of the Inner City west of Gilbert Street and south of Court Street is designated for mixed use on the 1983 Update plan map, The intent was that Individual parcels within the area should develop for primarily high-density residential uses, commercial uses, or a mixture of the two. Approximately one-third of the area is publicly owned. The zone designations are presently Community Commercial (CC -2) along Gilbert Street, Prentiss Street to Dubuque Street, and along Dubuque Street south of Prentiss Street. High-density residential (RM -145) and the Central Business Service zone (CB -2) dominate the remainder of the area. High-density residential uses are favored in this area since it is close to the employment and retail center of downtown and the University campus, and is a prime area for redevelopment. Much of the RM -145 land remains under-utilized. Recent changes in the Zoning Ordinance have made development in the high-density residential zone more economically feasible by reducing the building height required and, thereby, the cost of construction. Development in this area should continue to be monitored and additional measures taken, as necessary, to foster the desired redevelopment. Another part of this subarea which is under-utilized is the commercial area along Gilbert Street. Historic structures of varying value line the west side of Gilbert Street from Prentiss Street to Court Street. Some rehabilitation and re -use have taken place. Full - use of these existing structures is limited by the inability to provide parking on-site; most of the buildings cover the entire site. Efforts are being made to improve Malden Lane, to the rear of these structures, as a parking area. Revitalization of this commercial area may also require re-evaluation of the proper commercial zoning designation. This will not require revision of the 1983 Plan since a change could be accomplished under the existing general commercial designation. This land use designation should, therefore, be retained. Immediately north of this part of the Inner City Area are three blocks between Clinton and Gilbert Streets and between Court and Burlington Streets. These blocks have been targeted by some members of the community for expansion of the Central Business District. A study of the downtown and the ramifications of such a change in land use 121 I . . south of Burlington Street is scheduled for FY90. The results of that study may have an impact on land use decisions in the Inner City area south of Court Street. S. Schools. Presently, only one elementary school, Horace Mann, is located in the study area. Longfellow School, while outside of the defined study area boundaries, also serves as a neighborhood school for portions of the Inner City Area. Both schools are presently operating below capacity and could accommodate additional students. No additional schools have been proposed for the Inner City Area on the current Comprehensive Pian Map, and as higher density development has traditionally generated fewer school -aged children per unit, the need for additional schools in this area is unlikely. 6. Parka/Open Space. The 1983 Plan and the Open Space section of this Plan recognize the particular need for neighborhood open space in high-density residential areas. Multi -family development which does not have the benefit of usable private yard space may require greater public open space to ensure neighborhood livability. After an open space needs assessment of the Inner City and other developed parts of Iowa City is completed, measures such as density bonuses in exchange for open space should be instituted to encourage the provision of open space in high-density areas. It is anticipated that the proposed Iowa River corridor buffer and trail system and existing school sites will fulfill some of the open space needs of the Inner City Area. RECOMMENDATIONS 1. Rental and owner -occupied housing rehabilitation programs should be continued and enhanced. 2. Local tax incentives to encourage Investment in neighborhoods should be investigated. 3. Neighborhood planning areas should be formed to foster grass roots Identification of neighborhood problems and solutions and the preservation of neighborhoods. 4. The City should facilitate the nomination of individual historic buildings for the National Register of Historic Places. 5. Historic districts should continue to be a tool for the preservation of existing building resources. 6. To foster private property owner's Interest in the preservation of historic structures, the Historic Preservation Commission should continue to educate the public In the benefits of historic preservation. 7. The feasibility and desirability of permitting commercial uses, particularly small professional offices, in existing older structures in specified areas should be investigated as a tool for saving those structures. 122 fr I.l 8. In the Mercy Hospital area, the land use designation shown on the 1983 Plan should be retained with the old Central Junior High and playfield site plus the lot immediately east of the old playfield also shown as commercial office. 9. The high-density residential area south of Court Street and west of Gilbert Street should continue to be monitored to determine if public sector measures should be taken to foster redevelopment. III J 10. Upon completion of the downtown study, the portion of the Inner City area immediately n south of Court Street should be evaluated to determine If the land use designations I I shown are appropriate. 11. No new school sites need be shown on the Plan at this time. k t 12. Upon completion of a needs assessment for open space in the Inner City, methods to pattain open space through private sector development projects should be Investigated. rDevelopment of the Iowa River Corridor buffer and trail system may fulfill part of the Inner City's open space needs. 4fr1OF .0 t i u, l l I�I 4fr1OF .0 INNER CITY AREA FRINGE AREA 5 STUDY Study Area Fringe Area 5 is a portion of the City's extraterritorial area that is located within two miles of 71, the City's eastern corporate boundary and is bounded by Interstate 80 on the north and U.S. Highway 6 on the south. Most of the area within one mile east of Iowa City is zoned RS, Suburban Residential, which permits large lot, single-family residential development. One mile r further east, A-1, Rural, zoned land predominates. The Johnson County Zoning Ordinance states that this zone is "Intended to preserve agricultural resources and to protect agricultural land from encroachment by urban_ land uses." The northwest quarter of Area 5 is located in a+ the Ralston Creek watershed which drains toward Iowa City. The balance of the area, like .,� southeast Iowa City, is in the Snyder Creek watershed which drains away from the city. Comprehensive Plan Studies of the urban fringe area were not included in the 1983 Comprehensive Plan Update. �. The Fringe Area Policy Agreement between Johnson County and Iowa City, adopted in December, 1963, following adoption of the 1983 Plan Update, is, however, an element of this update of the City's Comprehensive Plan. The purpose of this study of Fringe Area 5 is to Identify development pressures east of the Iowa City corporate limits, to evaluate the development policies recommended in the fringe agreement for Area 5 and to determine i whether these policies continue to be consistent with the City's development goals and objectives. Issues I 1. Development and Annexation Pressures Infrastructure Improvements. Certain Infrastructure Improvements within the City may encourage full development of the eastern part of Iowa City which may, in turn, result in development and annexation pressures outside the corporate limits. Recently _ completed Improvements to Scott Boulevard between Court Street and Rochester Avenue have upgraded this roadway to allow it to function as a major arterial street and truck route for industrial development to the south. Proposed sewer system Improvements are evoected to resolve wet -weather surcharging conditions in the Rundell Street and Lower Muscatine trunk sewers that have deterred full development of eastern j Iowa City. These Improvements will allow unplatted land within the corporate limits to be sewered. — As with all sewers, additional capacity is designed In the collection system to accommodate more density than anticipated. This is done strictly as a precautionary measure to ensure that the system never needs to be replaced or upgraded at a higher cost to accommodate an unforeseen higher density of development due either to i - 124 changes in land use patterns or to future annexation. The result is paradoxical, however, as the added capacity may be seen as an opportunity by landowners outside the city limits to tap into this resource, not previously available, for urban type development. Annexation pressure will, therefore, occur. Land Use Opportunities. While the County zoning ordinance permits suburban residential development within that portion of Area 5 one mile east of Iowa City, the development policies of the Johnson County/Iowa City Fringe Area Agreement may have acted as a disincentive to residential activity in Area 5. The Suburban Residential (RS) zone allows low density residential development on lots at least 20,000 square feet in M area and 100 feet in width provided those lots are served by a communal sewer and a water supply. If not served by common facilities, each lot must be at least 40,000 square feet in area. Any development within one mile of Iowa City's eastern corporate limit, however, is required by the fringe area development policies for Area 5 to comply with the City's Urban Design Standards. All streets within these developments must meet the same j design specifications imposed upon new streets constructed within the city. All storm sewer, sanitary sewer and water distribution systems should be Installed but capped until municipal services are extended to the outlying development. Until these systems are linked to the Iowa City systems, however, the new subdivisions must be served by communal sewer and water facilities or individual septic systems and wells. If the policy is strictly followed, the cost per acre of all of these Improvements generally cannot be recovered if development is restricted to one to two lots per acre. Development, �t therefore, is inhibited. To make residential development cost-effective, developers of land within the portions of the urban fringe in which City Urban Design Standards are imposed may be inclined to petition that their land be annexed to the City. This would enable access to the City's Infrastructure and permit development at urban densities. The cost of development is, therefore, reduced and development opportunities are improved. Improvements to Scoff Boulevard and the municipal sewer system will make development opportunities east of the corporate limits more attractive. These Improvements, coupled with the opportunity to develop at urban densities, are expected r to precipitate requests to annex land within Area 5 that is in the service area of these IV improvements. 2. Proposed Annexation Policy i Accommodating Growth. As discussed in the annexation policy section of this plan update, the present corporate limits encompass sufficient land to accommodate the anticipated rate of residential development well Into the future. For the purpose of accommodating population growth, therefore, annexation of land within Fringe Area 5 Is not necessary. 125 /09/ Without consideration given to potential development east of the city, the East and - Northeast area studies noted that development within those areas alone will challenge the capacities of schools serving these areas and may require renovating and/or expanding existing schools or constructing new schools, Residential development at urban densities east of Iowa City will only escalate the need to address school capacity constraints. As can be seen, annexation carries with it responsibilities for a significant expansion of services. City policy on this Issue should, therefore, carefully weigh the costs and benefits of such an action. 126 Service Expansion Requirements. Serving land east of Iowa City would require the ^ extension of additional local trunk lines and may ultimately require construction of a ' sizeable relief sewer to accommodate development within the portion of the system serving the Ralston Creek watershed. To serve residential development within that portion of Area 5 located in the Snyder Creek watershed, it is anticipated that, at a minimum, either of the two lift stations serving southeastern Iowa City would have to be upgraded or a new lift station constructed to serve an area within one mile east of Iowa City. No municipal commitment has been made, at this time, to Initiate these Improvements. Although proposed wastewater system improvements will create development M, opportunities within the community, the excess capacity of the upgraded municipal sewer system will not allow full development of all undeveloped land within the t existing corporate boundaries. The developable land analysis section of this plan j r update estimates that existing undeveloped land which is currently zoned for single- E family and multi -family residential uses could accommodate at least 31,830 people. However, the City's Public Works Department anticipates that, if the excess capacity I•f of the improved wastewater treatment system is committed exclusively to residential ! development, the system may be capable of only serving up to 12,475 new residents. This estimate may be liberal, however, since contributions from sources such as L; infiltration and increased flows are difficult to predict until the system is on-line. This also ignores the sewer service requirements of additional commendal and industrial W development. All in all, while the new sewage treatment plant is designed to permit i, capacity expansions, the expansions required to allow full development of all unplatted land within the city represent significant municipal capital improvement commitments iwhich are not being planned. J In addition to future sewer system improvements, development east of the corporate limits may require water system improvements, and police, fire protection and sanitation services would have to be extended to serve the annexed area, Library and transit services and parks and recreation facilities would also have to be expanded to accommodate new residents. Without consideration given to potential development east of the city, the East and - Northeast area studies noted that development within those areas alone will challenge the capacities of schools serving these areas and may require renovating and/or expanding existing schools or constructing new schools, Residential development at urban densities east of Iowa City will only escalate the need to address school capacity constraints. As can be seen, annexation carries with it responsibilities for a significant expansion of services. City policy on this Issue should, therefore, carefully weigh the costs and benefits of such an action. 126 ■ <.. Completing Existing Neighborhoods. The annexation policy refers to the desirability of annexing land to complete existing neighborhoods. Providing municipal services to complete neighborhoods assures that sufficient population exists to support the services required within that neighborhood. Partial or fragmented neighborhoods, on the other hand, are inefficient from the standpoint of neighborhood service provision. Residential neighborhoods are typically cohesive units that are unimpaired by physical barriers which inhibit Interaction among the residents. Scott Boulevard is an arterial street that effectively separates uses to the east and west. Inappropriate development could result in fragmented neighborhoods east of this right-of-way. Annexation of any land east of the municipal boundaries, if deemed cost-effective, should, therefore, take into consideration the amount of land required to establish a complete neighborhood in which the efficient provision of services can be assured. �I Development Patterns. Because eastern Iowa City will substantially benefit by the proposed wastewater system improvements, full development of this part of the city may be possible. As a result, the eastern corporate boundary is not expected to be perceived by landowners as the limit of development opportunities in this part of the community. Requests to annex land within Fringe Area 5 are, therefore, anticipated. The City must give careful consideration to any request to annex land within the fringe area and must weigh each request in the context of the growth management policy espoused in the Comprehensive Plan. The extension of services to annexed areas can only be achieved by limiting development opportunities within the existing corporate boundaries. Only with a significant expansion of services can residential, commercial and Industrial development within the community be unimpaired by the extension of municipal services to the urban fringe. Development of Fringe Area 5 should only occur according to the development sequence schedule included in this plan update and only in accordance with the out -of -sequence development policy as it continues to apply to Area 5. In addition, development within Fringe Area 5, one mile east of the existing corporate boundary, should only occur in accordance with the City Urban Design Standards which require installation of the full complement of municipal infrastructure. Streets, sidewalks and storm sewer, sanitary sewer and water distribution systems within fringe —. development one mile east of the city must conform to the same design standards imposed on development within the community. In areas in which annexation pressures are anticipated, the application of City Urban Design Standards assures that the needed Infrastructure is in place at the time of annexation and relieves the City of the costly expense of installing these Improvements at a later date. Industrial Development. Preference Is given to Industrial development over residential development since Industry is basic to any community's economic well-being and growth. The development policy for Fringe Area 5 recommends expansion of the Business Development, Inc. (BDI) Industrial park eastward to encompass a tract of land east of Scott Boulevard, south of the Iowa Interstate Railway tracks and north of a local road. It would be to the mutual benefit of the City and future industrial development 127 /o9/ if this territory were incorporated Into Iowa City. Industrial development would gain access to municipal services, particularly sewer and water, and the community would j realize the tax revenue generated by industrial entitles. a The Heinz lift station, immediately west of Scott Boulevard and about 1250 feet south of the railway right-of-way serves industrial development within BDI. It is difficult, at this 1 time, to evaluate the capability of this lift station to accommodate industrial development outside the corporate boundaries. Once the upgraded wastewater treatment system is on-line, however, the excess capacity of the system serving eastern Iowa City can be 1 assessed and the extent of the system's capability to serve new areas can be evaluated. The City should take positive steps, however, to assure that sewer capacity is available to serve future industrial growth east of the present corporate boundary by controlling I•i the extent of residential development at urban densities permitted in the urban fringe. RECOMMENDATIONS i.� 1. For the purpose of accommodating expected population growth, annexation of land east of Iowa City is not needed. 2. Additional capacity designed in sewer systems should not be viewed as an opportunity by landowners outside the city limits to use up this available capacity. 3. If land east of the existing corporate limits is annexed for residential purposes and if the extension of municipal services to serve the area is deemed cost-effective, the extent — of annexation should be governed by the amount of land required to establish complete neighborhoods. :j 4. To facilitate industrial growth and development in Iowa City, land east of Scott Boulevard and south of the Iowa Interstate Railway should be Incorporated into the community. 5. Agricultural uses are encouraged to continue in Fringe Area 5. Residential uses for farm family purposes will be considered depending on soll and site conditions, Unless annexed to Iowa City, development of existing residentially zoned land should be limited by the densities permitted by the Johnson County Zoning Ordinance. 6. City Urban Design Standards should be imposed for any development within one mile of Iowa City's eastern limits. County and City Rural Design Standards should be applied to regulate any residential development beyond one mile of Iowa City's eastern limits. 128 i FRINGE AREA 6 STUDY I� ,! Study Area I iFringe Area 6 is that portion of the City's extraterritorial area located within two miles of the City's southern corporate boundary. This area is bounded by U.S. Highway 6 on the north and I east and a tributary of Old Man's Creek on the west. Most of Area 6, within one mile of Iowa City's southern corporate limits, is zoned for RS, Suburban Residential, use. This zone permits r" single-family residential development on lots with minimum areas of 20,000 square feet, J provided the lots are served by communal sewer and water supply facilities; otherwise, each lot must be at least 40,000 square feet in area. One mile further south, A-1, Rural, zoned land predominates. The Johnson County Zoning Ordinance states that this zone is Intended to j preserve the inherent rural quality of the area by "...preserving agricultural resources and protecting agricultural land from encroachment by urban land uses." Certain land within Area r. 6 adjacent to the Iowa River is zoned A-2, Resort, which permits, among other things, boat docks, beaches and bathhouses and accessory uses associated with water sports. i Comprehensive Plan T The 1983 Comprehensive Plan Update did not include studies of the urban fringe area. The Fringe Area Policy Agreement between Johnson County and Iowa City is, however, a part of this update of the City's Comprehensive Plan. The present fringe area development policy for Area 6 states that agricultural use is the preferred land use for the area. Depending upon soil and site conditions, residential uses for farm family purposes will be considered. Development of existing County residential zoning districts Is expressly limited by the fringe agreement to _ annexation and the ability to provide municipal services to these residential districts. According — to the policy agreement, City Urban Design Standards are to be Imposed on any development within one mile of Iowa City's southern limit. Beyond one mile of the corporate limits, County i and City Rural Design Standards are applied. The purpose of this study of Fringe Area 6 is to Identify factors that may encourage - development south of the Iowa City corporate limits, to examine the development policies for _ Area 6 in light of those development pressures and to determine whether these policies continue to be consistent with the City's development goals and objectives. i Issues 1. Development and Annexation Pressures. Impending construction of the City's new wastewater treatment facility within the central portion of Area 6 is expected to generate speculation as to development opportunities available given this area's proximity to a desirable municipal service. With extension of a major Interceptor sewer line to the new plant, through an area outside.the City limits, pressure to annex land from the present corporate boundary and within the service area of the Interceptor sewer is anticipated. 130 I 1 I The pressure to annex will be due, in part, to direct tie-in possibilities to the Southeast Interceptor Sewer by means of drop connections which are currently proposed at 1200 - foot intervals along the interceptor line. Due to the size and depth of the proposed Southeast Interceptor Sewer, this system Is physically capable of serving much of Area 6 by means of gravity flow. Development of Area 6, however, would require extension of trunk lines laterally from the interceptor r sewer at drop connections. These extensions and connections are expected to generate significant development costs. Providing municipal sewer service to the portion of Area 6 west of the Iowa River would also require a significant capital outlay to construct a river crossing. All of these improvements represent expenditures that are not proposed In the City's wastewater facilities improvement plan. i 2. Environmental Considerations. The Iowa Department of Natural Resources (IDNR) has identified two wetland areas within proximity of the proposed wastewater treatment facility and the southern segment of the Southeast Interceptor Sewer. Both of these wetlands are depicted on Figure 5 which Illustrates environmental areas in southern Iowa City and in the vicinity of the new sewage treatment plant. i ^� The smaller of the two wetlands Inventoried by IDNR covers an area one to two acres f In size and Is located west of Bon Aire Mobile Home Lodge within Iowa City. This �) wetland is located beyond the 200 -foot wide temporary easement associated with proposed sewer construction activities. The second wetland area, significantly larger j in size, is located east of the proposed treatment facility and within Fringe Area 6. This wetland is also located outside of the proposed sewer route. �i Federal regulations mandate that Federally financed or assisted construction projects, such as the proposed Iowa City wastewater system Improvements project, are to avoid, to the extent possible, activities associated with destruction or modification of wetlands. — The limits of proposed municipal sewer construction activity will not encroach on known wetland areas and erosion control measures will be Implemented along the construction — route to minimize the Impact of construction on sensitive lands. Consideration should also be given to discourage any development that will threaten the viability of these wetlands. As noted, construction of the City's new wastewater treatment facility within the center of Fringe Area 6 is expected to precipitate `i development pressures beyond Iowa City's southern corporate boundary. Consistent with the City's Environmental Policies, development activities within Area 6 should be .... carefully monitored to assure that these sensitive lands are neither modified nor degraded. 3. Proposed Annexation Policy, The annexation policy section of this Plan Update has established that, since sufficient land exists wkhin the community to accommodate anticipated development, annexation of land for residential purposes is not justified. The City has also advanced the policy that development should take place within the current corporate boundaries and adjacent to present development where sewer and other municipal services are available. 131 /t09/ i i A significant amount of undeveloped land exists in southern Iowa City, east of the Iowa River, that will be in close proximity to sewer service. Although the Southeast Interceptor Sewer will traverse the eastern portion of this undeveloped part of Iowa City, present sewer design does not call for extending trunk lines through the area concurrent with construction of the water pollution control plant. Development of the South Area of Iowa City will be discouraged at least until such time as other developable land within the corporate boundaries that requires less costly capital expenditures is developed. This policy of compact and contiguous growth also dictates, therefore, that full development of the South Area precede extension of municipal services to existing unincorporated areas to permit residential growth. Since sufficient developable land is available city-wide within the present corporate limits to support population growth well into the future, annexation of land within Fringe Area 6 to accommodate residential growth is currently not justified. Annexation of additional land is also not recommended when such annexation may foster noncontiguous growth or threaten sensitive lands. However, the City recognizes that proximity to a desirable municipal resource, namely sewer service, will precipitate pressures to permit residen- tial development within Area 6 at urban densities. In anticipation that land within Area 6 may, in the future, be incorporated into Iowa City, City Urban Design Standards should be applied to regulate all development within the entire area. Compliance with City Urban Design Standards means that all streets within a fringe area development must meet the same design specifications imposed upon new streets constructed within the city. In addition, provisions (other than an easement) must be made for the installation of sidewalks and of storm sewer, sanitary sewer and water distribution systems that conform with the municipal design standards for this Infrastructure. Within fringe areas in which annexation pressures exist, requiring the same development standards as are Imposed upon urban development assures that the calibre of development within the annexed territory is the same as development within the corporate limits, This requirement also ensures that the needed infrastructure Is in place at the time of annexation which relieves the City of the costly expense of j retrofitting these systems within developed areas. RECOMMENDATIONS 1. For the purpose of accommodating expected population growth, annexation of land within Fringe Area 6 Is not Justified. 2. Full development of the South Area of Iowa City should precede extension of municipal services to Fringe Area 6. i 3. Except for parcels presently zoned for residential uses, agricultural uses are the preferred land use in Area 6. Residential uses for farm family purposes will be considered, depending on soil and site conditions. Development of existing residential 132 zoning should be limited by the densities permitted by the Johnson County Zoning Ordinance. Sensitive lands within Fringe Area 6 should be protected and preserved. City Urban Design Standards should be imposed for any development within Fringe Area 6. 133 J i i I I ; I' I. i— 4. 5.

NOW, THEREFORE, the parties hereto, do agree for themselves and their respective successors to the following amended policy for Area 4: AREA 4 Policy A limited amount of residential development on the properties with direct frontage or access on Rapid Creek Road will be permitted. On other property within Area 4 with access out to Highway 1 and access to gravel surface roads, residential development should be discour- aged, and encouraged to take place in Area 3 and other parts of the County zoned for residential development. Agricultural use is the preferred use on these other properties; residential uses for farm family purposes will be considered depending on soil and site condi- tions. Residential growth along Rapid Creek Road will be guided by perform- ance standards designed to: 1. Keep County road maintenance costs and other services at an ac- ceptable level; 2. Preserve the rural character of the area; 3. Conserve prime agricultural land for farm use; 4. Minimize conflict between residential development and existing farm uses; and -2- 5. Mow for the protection of environmentally sensitive areas, such as steep slopes, wetlands and forested areas. Actual development of individual sites along Rapid Creek Road will be accomplished by matching these standards to the specific land charac- teristics, including road access safety, steep slopes, floodplains, woodlands, existing agricultural uses and prime farmland. County service level limitations, primarily road service capacity, should provide an overall basis for setting the density standards in the area. Along Rapid Creek Road large lots will not be required. Where the tracts of land being considered for subdivision are large enough, the performance standards could be facilitated through the clustering of smaller building lots. Clustering is a development design technique that concentrates buildings in specific areas on the site to allow the remaining land to be used for recreation, Gammon open space, conserva- tion of prime ag land and preservation of environmentally sensitive areas. The carrion open space created through the clustering process could be secured through the use of restrictive covenants obtained as a part of a conditional zoning process. Implementation; 1. Implementation of this policy for development along Rapid Creek Road will require amendment of the County Zoning Ordinance. This amendment could be accomplished by adding a new section on planned residential development, which incorporates the use of performance standards, site plan review and elements of conditional zoning, or by use of overlay provisions. 2. The density for development of lots having frontage on or access to Rapid Creek Road should be one dwelling unit per three acres. 3. All zoning requests will be reviewed for conformance with the policies established for Area 4. 4. Development of existing zoning within Area 4 will be required to comply with County and City Rural Design standards. S. No annexation of this area is anticipated in the next three year review period. This amendment to the agreement shall be filed with the Secretary of the State of Iowa, and with the Johnson County Recorder in compliance with Chapter 28E, Code of Iowa. 0 -3- Dated this day of , 1986.

AREA DEVEGOPMENP POLICIES & IMPLEMENPATION MEASURES �J The parties accept and agree to the following Area Development Policies and Implementation Measures regarding annexation, zoning, and subdivision review for the various designated areas outlined on the attached map. Statement of Intent — In order to facilitate the purposes of Chapter 93A of the Code of Iowa and to further the policy of this State to provide for the or er y use and _ development of land and related natural resources in Iowa for residential, commercial, industrial, and recreational purposes, preserve private property rights, protect natural and historic resources and fragile ecosystems of this state including forests, wetlands, rivers, streams, lakes and their shorelines, aquifers, prairies, and recreational areas to promote the efficient use and conservation of energy resources, to promote the creation and maintenance of wildlife habitat, to consider the protec- tion of soil from wind and water erosion and preserve the availability and -- use of agricultural land for agricultural production, through processes that emphasize the participation of citizens and local governments: and, In the interest of providing for orderly and efficient development patterns in those areas of Johnson County within the two-mile extraterritorial jurisdiction of Iowa City and in order to provide services for such development at the least cost to all of the people of Johnson County, the City of Iowa City and Johnson County agree, as provided in Chapter 28E of the Code of Iowa, to the following Development i r 1 I - Page 2 iPolicies and Implementation Measures regarding annexation, zoning and subdivision review for various designated areas outlined on the attached I - map. i The 28E agreement between Johnson County and the City of Iowa City will pertain to the entire two-mile extraterritorial jurisdictional area of Iowa City. j AREA 1 Policy Agricultural use is the preferred use in Area 1. Residential uses for farm family purposes will be considered depending on soil and site conditions. The policy regarding this area should be -7 reevaluated at such time as the potential office research park development anticipated in the northwest quadrant of Iowa City is realized. i Implementation: u 1. All zoning requests will be reviewed for conformance with the policies established for Area 1. 2, County and City Rural Design standards will be applied to regulate development within existing residential zoning. (City Urban Design Standards will not apply). ' 3. No annexation of this area is anticipated in the three year review i period provided for in Section III. AREA 2 Policy This area should develop as low to medium-density residential use; large scale commercial development is inappropriate due to the proximity of existing residential uses, the I-80 and Dubuque Street interchange, and the curvature of Dubuque Street. Limited commercial uses may be considered when integrated as part of a proposed residen- tial development. 'Implementation: 1. The County will adopt Planned Development Performance Standards (PUPS). 2.

ADMINISTRATIVE POLICIES The parties accept and agree to the following administrative polices: Zoning regulation as a rule is the county's prerogative while subdivision regulation in these areas comes under a city's authority. Annexation is also primarily under exclusive rule of cities. Each of these activities, however, affect both jurisdictions and have produced a clear and pressing �49� Page 6 need for coordination and joint administration. To that end, the City and the County agree to the following procedures for administration of land use regulations. A. zoning Regulation: 1. Zoning regulation for all unincorporated territory will remain under the authority of the Johnson'County Zoning Ordinance and the provisions of Chapter 358A, Code of Iowa. 2. Implementation of measures outlined in this agreement which call for rezoning of specific areas or the adoption of new regulations will be undertaken within the 3 year review period of this Agreement. i 3. Each request for zoning of property within Areas specified in this Agreement will be forwarded to the City for review and comment prior to the public hearing before the County Zoning Commission. Any zoning change will conform with the policies identified for the Area in which the requested change is located. B. Subdivision Regulation: 1. Subdivision of land within the 2 mile extraterritorial jurisdic- tion will be required to conform to either the Rural Design Standards of the City and of the County or City Urban Design Standards in accordance with the Area Policies and Implementation Measures specified in this Agreement. 2. Persons wishing to subdivide land within the Areas specified in this Agreement shall be required to file, at the same time with both the City and the County, a subdivision application, the processing of which shall be coordinated to ensure concurrent review by both the City Planning and Zoning Commission and the County Zoning Commission. 3. Subdivisions of lard into less than three lots will continue to be regulated by the County. C. Annexation: 1. Iowa City will annex territory only in accordance with the Policy Statements and Implementation Measures specified in this Agree- ment. 2. Requests for annexation or severance of property within the Areas specified in this Agreement will be forwarded to the County, upon receipt of the application by the City, for review and comment prior to consideration by the Iowa City Planning & Zoning Crnmission. 71 Page 7 .I _ SECTION III.

FOII,ANNE%ATION I ^�"'I I� _ i j ♦Q I I - NEIGHBORHOOD OPEN SPACE. METHODOLOGY Development of Open Space Zones and Districts With the scope of the plan to study open space needs at the neighborhood level city-wide, the city was divided into smaller planning units. Each unit represents a given geographical area -. of the city in which residential properties in the particular unit share the same limitations and/or opportunities for open space. These planning units are the basis for the plan. t. Open Space Zones: i As a first step toward defining the smaller planning units (Open Space Districts) the city was sectioned into broad regions known as Open Space Zones. This was done by distinguishing between established residential areas and newly developing residential J areas. As a result, three (3) Open Space Zones were identified; two represent the already developed portions of the city - the Inner -City Zone and the Developed Zone, and one represents the substantially undeveloped portions of the city - the Developing Zone. The two zones representing the developed sections of the city were further distinguished on the basis of housing density and type, with the Inner -City Zone consisting primarily of the downtown area where the greatest number of multi -family dwellings exist. A distinction between these three areas was necessary since different planning techniques will be required to evaluate the need for open space as well as for developing a plan to acquire the needed open space within these different environments. Outside of housing and population density, the primary difference between each of these three zones Is the availability of undeveloped open space. The availability of undeveloped open' space, both in quantity and quality, decreases dramatically progressing from the Developing Zone to the Inner -City Zone. Non-residentlal areas of the city were excluded from the Open Space Zones and Open Space Districts since these areas do not generate a need for open space, nor are they expected to contribute to the open space needs of a District. 2. Open Space Districts: As mentioned previously, the open space, districts are the planning units for the development of this plan. It is at the district level that an assessment of need will be determined and open space calculations made by using supply and demand analysis. As a beginning for denting the districts, the locations of all existing parks and their service areas were identified. Boundaries were then determined by using the following criteria: a, Focal point: Neighborhood parks are often the local point of neighborhood activity (I.e, social events, gathering place during leisure hours, etc.), Each district was dented so as to Include existing parks, or configured in such a I_ /09/ manner as to permit the development of open space geographically centered within the population of the district. b. Physical boundaries: With pedestrian accessibility as the primary goal, physical barriers were used to define the limits of each district. District boundaries were set by using one or more of the following: • Natural features, such as steep slopes, vegetation, and stream valleys; • Major streets, highways and railroads. Determination of Open Space Criteria As noted earlier, the delineation of individual zones was based upon existing land use patterns, housing types and densities, population characteristics, and topography. Districts within each zone also share similar characteristics and opportunities with regard to the availability or accessibility of open space. Based upon each zone's characteristics, the function and accebe acceptable open tability of open space potentiallyace will and thestandardusediforrent. As a result, the calcu calculating needed opeteria for n space within dtermining of the three zones will be somewhat different. Developing Zone: District Needs Assessment process The first step in this process was to compile known factual information about each District, such as population, land area, and zoning. With this information established, the next step was to apply the needs assessment formula: [(A x OU x PDU) + CP) x 3/1000 - (SS + PS) = OSD Following is an illustration showing how the needs assessment process was applied to each district. EXAMPLE: DISTRICT 1. Previously Developed Area: A. Current Population: (CP) Note: Current population figures were determined by using block/group data of the 1980 U.S. Census. 2. Non -Developed Area: A. Non -Developed Acreage by Zone: (A) Note: Area of each zoning category was determined by use of a planimeter. 8. Projected Population: (A x DU x PDU) Note: The total projected population was determined by taking the area (A) of a zone multiplied by the maximum permitted number of dwelling units per acres (DU) adjusted to 65% (DU x .65), the product of which is multiplied by the number of persons per dwelling unit (PDU) which is 2.33 as taken from the 1980 U.S. Census. j 3. Total Open Space Need: [(A x DU x PDU) + CP] X 3/1000 i r• Note: Projected and current population are added together and multiplied by the open t space standard (0.003) to determine the total open space need. 4. Credit for Existing Open Space: (SS + PS) Note: Credit is granted for existing public school sites (SS) up to 25% of the school's playground/sports field area or five acres, whichever is less, and public parks (PS) up I to seven acres. 4.J i 5. Open Space to Be Dedicated: (OSD) i Note: Total open space need minus credit for existing open space. If remainder is positive, then open space is required to be dedicated, if remainder is negative, no dedication is required. f� i { J District analysis for each of the eleven (11) Open Space Districts of the Developing Zone is provided below.
