P. 55 93 -- Delete this sentence and substitute: "Require a minimum open space allocation as part of the subdivision process." p. 119 & Beginning with the last paragraph on page 119, the text should read 120 as follows: "Therefore, because the City Council deems it requisite for the protection of the public interest that an amount of land for parks based on the standards specified in this Comprehensive Plan be provided for the residents within a subdivision, the City Council has expressed interest in the adoption of a Minimum Open Space requirement. Such a requirement, as a condition to plat approval, would require a developer to provide a minimum amount of common open space per dwelling unit, in order to reserve land for parks to serve residents of the developed subdivision. The Minimum Open Space requirement, as outlined by City Council, would allow the developer two alternative methods of providing open space: (1). the developer may sot aside within the subdivision, open space to be maintained privately (e.g., through a homeowners' association); (2) if the City wishes to incorporate the developer's open space into a neighborhood park, the developer may dedicate the open space to the City. In addition, it may be possible for the developer to pay to the City fees in lieu of open space or parkland. Certain restrictions on the quality and location of the land which could be provided as open space would be specified in the ordinance to insure adequate usable space for active and passive recreation. However, portions of steep slope areas and portions of storm water detention sites would possibly be accepted as part of the required open space. MICROFILMED BY JORM MICR+LA6 MILROFILMED BY JORM MICROLAB City Council May 26, 1978 Page 2 • CEDAR RAPIDS AND UES MUIMES, IOWA A minimum open space requirement would provide a mechanism which would allow the developer to achieve the same number of lots or dwelling units within the subdivision as would have been attainable without the provision of open space. Consequently, the open space requirement would not increase and may in fact decrease costs for the developer or home buyer. Approval of any subdivision plat by the Planning and Zoning Commission and the City Council would be contingent upon conformity of the sub- division with the Comprehensive Plan and the Minimum Open Space Requirement. The Minimum Open Space 'Requirement has a legal status similar to mandatory park dedication. The City Attorney's memorandum of March 5, 1974, to the Mayor and City Council regarding mandatory dedication concluded: "The status..." There are no changes on the rest of page 120 and 121. In order to clarify the intent of the Public/Semi-Public land use indicated on the Comprehensive Plan Land Use Map, the following paragraph will be inserted on p. 87 below the Public/Semi-Public heading: Existing and proposed parks, stream valleys, governmentally owned land, and privately owned land on which various community facilities are located were given one of three Public/Semi-Public designations on the Comprehensive Plan Land Use Map. These designations do not indicate how such land will be zoned, nor imply that all land within the Public/Semi-Public category will be acquired for a public use. Generally it is the intent of the Plan that governmentally owned land will eventually be shown as within a Public Zone, while privately owned land will be given a zoning designation appropriate to the use on the land and the area surrounding it. p. 117 (e) and (f) have been combined into a single Public Zone. (e) and (f) will be deleted and Comprehensive Plan Land Use Map Designation (e) will be "Public: Zone for Governmentally Owned Land." p, 87 "Englert" Tract -- On the recommendation of the Legal Staff the sentence, "The City is unable to purchase this tract for open space at this time." has been deleted.

The Plan is meant to be a flexible working document which can be adapted to the changing conditions of the community. The previous Comprehensive Plan was prepared in 1962. since then, Iowa City's population has increased over 40%, and many other changes also occurred. That Comprehensive Plan no longer reflected conditions in Iowa City, and did not provide an up-to-date policy framework for current decision-making. The courts have increasingly used a city's comprehensive plan in ruling on land development decisions. In its attempt to balance the wishes of individual landowners with the overall public good,'the City must show that its decisions have been based on an adopted plan which clearly states goals, objectives and policies for future growth. The new Comprehensive Plan provides background support and evidence for well thought out policies and planning, important for ensuring a logical pattern and intensity of land use within Iowa City. Various federal programs require cities to have a comprehensive plan before grant applications are considered. This new plan provides basic documentation for grant applications, and places Iowa City in an advantageous position for receiving federal funds. As discussed in the text (in the Capital Improvements Program and Budget section), the City is operating under financial constraints which must be considered in planning for the future. Therefore, the 1 110101 WHO !t1 JORM MICROLA13 • ULAk RAPW�) AND OL '411IL - .N„' to implement some recommended programs because al resources. an helps to set priorities for city improvements h as obtaining easements or rights-of-way for cways.

THE COMPREHENSIVE PLANNING PROCESS The Comprehensive Plan Coordinating Committee (CPCC) was established in February, 1976 "to make recommendations to the Planning and Zoning Commission related to the Comprehensive Plan on behalf of the resi- dents of Iowa City" (Rules of CPCC adopted May 3, 1976). The com- mittee was composed of four members of the Iowa City Planning and Zoning Commission and three members of the Iowa City City Council. (A fifth member of the Planning and Zoning Commission joined the com- mittee later in the year.) The committee worked with the planning staff, consultants, neighborhood organizations, and other citizens for a period of 2, years. During this time, various elements of the Comprehensive Plan were prepared. ELEMENTS OF THE PLANNING PROCESS 1. Citizen Participation Widespread citizen participation is essential to a successful planning process, to ensure that the final plan document reflects the desires and needs of citizens. Sasaki Associates, Water- town, Massachusetts, in cooperation with Attic and Cellar, Inc. Washington, D.C. were hired in October, 1976, as consultants to assist in the preparation of an ongoing citizen participation program and to help formulate surveys. The consultants worked with CPCC, city staff and citizens for a five month period. Initial citizen meetings were held in November, 1976. Over 400 members of various Iowa City organizations were invited to 3 il.MI C+ DORM MICROLAB L., by JORM MICROLAB CLOAit kAPIU5 AND AL '1k. !!1L. , V` these meetings including the Iowa City School Board and Adminis- tration, the University of Iowa and the Johnson County Regional Planning Commission. These organizations provided the first input of citizens' concerns for the future of Iowa City. Issues raised at these meetings provided initial guidelines to the City Council, CPCC, staff and consultants for formulating questions for the special and general surveys. The Consultants prepared a special survey, which was distributed to about 250 Iowa City residents in January, 1977, for the pur- pose of obtaining information about their concerns, priorities and ideas for the future of Iowa City. Information and comments from this special survey were used to prepare the People's Guide and Survey which was mailed to all Iowa City households in April, 1977. The People's Guide and Survey was intended to provide back- ground information, and to describe some of the alternatives and choices in planning for the future of Iowa City. This guide pre- sented some of the City's choices with regard to growth and an- nexation, transportation, housing, energy, human services, neighborhoods, and patterns of future development. Included with this guide was a questionnaire which all households were asked to complete. During the week after the People's Guide and Surve_ was distributed, five neighborhood meetings were held to discuss some of the issues raised and to encourage return of the questionnaires. Over 2,000 questionnaires were returned. Computer analysis of these questionnaires provided basic demographic information 4 DORM MICROLAB ' :, * UL.: fiy JURI.1 LIICRULAb 2 3 (.EUA,< kAVIJ'� ANC and indicated the residents' views on how the City should plan for future growth, housing, community facilities, transportation and environmental concerns. All sections of the population were represented by age, income and geographical location. Other neighborhood meetings were held on the Preliminary Proposal: Land Use Plan (mailed to all Iowa City households in February, 1978) as well as public meetings by the Planning and Zoning Commission and public hearings by the City Council. Reports and Studies Background reports and studies were prepared to provide basic information for use in preparing the plan. These reports are described in Section III of this document and are included in Appendix A. Issues and Alternatives Information from neighborhood meetings, surveys, reports and studies were used to prepare a list of basic issues to be ad- dressed by the Comprehensive Plan. A number of alternatives for resolving each issue were prepared by the staff, together with an analysis of the land use, social, economic, legal and environmental impacts of each alternative. CPCC discussed these major issues and alternatives and made recommendations on how they should be addressed in the Compre- hensive Plan. Using this direction a Preliminary Proposal: Land Use Plan was prepared and mailed to all Iowa City house- holds in February, 1978. During the week after the preliminary 5 A]CRol liMf.) 0 DORM MICROLAS ;II .,, BY JORM MICROLAB ILUA,< RAPIJ'� NI10 JL ',i • .t. plan was mailed, five neighborhood meetings were held by CPCC to elicit citizen comments on the plan. q,Pre oration of Plan Elements A revised draft of the Land Use Map was prepared using com- ments from citizens, boards, commissions and other governmental groups and staff. Using the Issues and Alternatives identified by CPCC and the findings from background studies, goals and objec- tives, recommendations and policies were developed for the City. In addition, a detailed explanation of the Comprehensive Plan Land Use Map was prepared together with definitions of the land uses. Development standards for various land uses are included in Appendix B. The rianntuy aua ---- meeting on this draft of the Comprehensive Plan Map and recom- mended a final version to the City Council. The City Council then held a public hearing on both the Map and Text of the Com- prehensive Plan. Following the adoption of the Comprehensive Plan by the City Council, a Zoning Ordinance map and text will be prepared to implement elements of the Comprehensive Plan. New subdivision regulations will also be prepared for this same purpose. For each addition or amendment to the plan, public meetings and hearings will be held by the Planning and Zoning Commission and the City Council prior to adoption. 6' AP Rw ivatit i0 JoRM MICROLAS ";. ,*J! :L'•!;u by JORM MICkOLAB • LEUAR kAPIJS ANU uta 'h- a' , - "' 3 Update of the Comprehensive Plan Documents The Planning and Zoning Commission will review and update the Comprehensive Plan documents periodically (approximately once every three years), to ensure that the plan remains a viable document. Amendments will be made as necessary, with public hearings being held prior to the adoption of any amendments. It is the responsibility of the Planning and Zoning Commission to initiate and make recommendations to the City Council for amend- ments to the Comprehensive Plan. 7 • -I Nf. RI ri II.

'^„ In order to provide basic information on existing land use, population, economics and other topics in Iowa City, and to document topographical and other natural features, a series of background reports were pre- pared by the planning staff. These background reports are included in Appendix A of this Comprehensive Plan document. These reports, which catalog existing conditions and recommend alternatives for solv- ing some existing problems, are summarized below. Much of the data in the Report on Population: Summar (January, 1977) is from the 1970 and 1974 federal censuses. The population of Iowa City was 46,850 in 1970, and 47,744 in 1974. The growth rate slowed to 1.9% in the early 1970's after growth increased by 40% during the previous decade. The census counts reflect a disproportionate number of 20-24 year olds in the population, a characteristic which can be directly attributed to the presence of the University of Iowa. In the Report on Population: Summary, projections suggest that the population will increase at a moderate rate of 500 persons per year. The 1976 Land Use Summar (January, 1977) includes a map of land use in Iowa City. Agriculture and low density residential were found to occupy over 50% of the city's land area at that time. The report com- pares land use in different areas of the city, and identifies several land use -related problems including mixed use areas, land use changes, and obsolete sites. s 1h Rid 1111tJ !0 JORM MICROLA13 m ,.. A ,L":,� BY JURM MICRULA6 LLUAtI RAVIbi AIdJ ,,L., �'..',t... . "' The Vegetation Guide (January, 1977) describes eight types of eco- systems found in the Iowa City area. Special considerations involving ecosystems are presented, along with ideas on how to more advantageously plan for future development. Report on Housing (March, 1977) relates that the rapid increase in the amount of housing stock during the 1960's has not been enough to offset the growing demand for additional housing in the Iowa City area. The projected housing requirement for Iowa City is approximately 310 units per year, assuming population growth continues as expected. The breakdown between renter and owner -occupied units can be expected to remain at about 54% to 46%. The Report on Housing suggests a de- crease in the minimum lot size and side yard requirements which could reduce single-family housing costs. The report recommends several de- sign elements for making multi -family housing more livable. The Trafficways Report (April, 1977) lists several existing problems in the trafficways system, including congestion at river crossings, inadequate cross-town arterials, under -utilization of the transit system and the disruption of residential neighborhoods by through traffic. Design solutions for some problems are suggested in the re- port, and alternatives for the locations of Freeway 518 and of Scott Boulevard are provided. Analyses and recommendations on the location of Freeway 518 have been prepared in addition to the Trafficways Report. Negotiations with the Iowa Department of Transportation to shift the location of the freeway further west have taken place; how- ever, a majority of the City Council is opposed to the construction DORM MICROLAB .L x;v BY JUkM MICkOLAB ILLUAtt kAPIJ'� ANIS ULA I - . of a four -lane freeway and prefers the construction of a two-lane (relocated U.S. 218) in this location. The Preliminary_ Bikeways Plan (March, 1976) was prepared to provide a continuous, safe and direct bikeways system in Iowa City. The Locational Factors Report (May, 1977) maps and synthesizes infor- mation on soils and topography, vegetation, trafficways, utilities, physical barriers, and distances from core areas in Iowa City. These factors were combined to form a composite map, and to provide guide- lines for recommended land use intensity. The Report on utilities (May, 1977) discusses both the public and privately owned utilities needed to serve Iowa City residents. The city provides both water and sewer service to residents. The present water treatment plant capacity is more than adequate for meeting peak demands and is capable of meeting future demands to the year 2000. The existing sewage treatment plant discharge at times exceeds the effluent limitations set by the federal Environmental Protection Ag- ency (EPA) and the Iowa Department of Environmental Quality (IDEQ). The proposed facility will remedy this problem and will provide in- creased capacity. Electricity and natural gas are provided by Iowa -Illinois Gas & Electric Company. The company is presently willing to supply an un- limited amount of electricity and foresees no problem in meeting future demand. Iowa -Illinois also foresees no problem in supplying natural gas to homes, but industries are already looking towards the use of alternative sources of energy. 10 .!lit 4WI !fI�T DORM MICROLA9 ...mj; :I_'A' c by JORM MILROLAb LLUAti iW ) I J:, ANO Ju !I- - , Land Use Concepts (June, 1977) reviews the characteristics and com- patibility of land uses found in the Iowa City area. The report in- cludes a brief analysis of alternative development patterns, including sprawl, core, node and corridor, and naturalistic. Comprehensive planning concepts reviewed in this report include neighborhood plan- ning, metropolitan planning, and natural features planning. The re- port suggests the use of buffering techniques such as site orientation architectural barriers, transitional uses, and landscaping to mini- mize land use conflicts. The Landforms Guide (June, 1977) reviews the significance of Iowa City's soils and topography in urban development. A map of the landforms and their generalized development limitations is provided in this report. Also included is a map showing the watersheds of the Iowa River and Willow and Ralston Creeks. The Community Facilities Report (August, 1977) includes a map of exist- ing public facilities and information about their size and operation. National standards for parks and schools are provided, although these standards cannot be directly applied to Iowa City without further adaptation. For the City Library, Police and Fire Departments, other public buildings and the Airport, discussion includes present opera- tion and inadequacies of existing structures. The Economics Report (November, 1977) catalogs statistics on the labor force, retail, wholesale, and services activity within Iowa City. 11 JoRM NiOCROLAS ;,.;t, a BY JORM MICROLAb (,_bAK kAP1J`, AIIu Jl, .'11..aL. • • 11 - Standards for the development of neighborhood commercial areas are provided. Data concerning manufacturing in Iowa City and economic activity associated with the University of Iowa, hospitals and health care is also included. The potential for future economic development is discussed. The Citizen Participation Report (December, 1977) reviews the City's efforts in providing opportunities for citizen input in the comprehen- sive planning process. The report covers the characteristics of survey respondents, and a summary of survey results. The Tree Planting Plan (November, 1976) recommends the use of trees and shrubs for shading, as windbreaks, for noise and erosion control, and for insulation. The City's tree planting regulations are included in this report. A list of appropriate street trees and tree -planting instructions are included. Another leaflet, Iowa city Guide to Parking Lot Landscaping, is available through the City of Iowa City and was prepared as a part of this background study. In addition to general background studies, a number of detailed studies and plans were prepared which contribute to the entire Comprehensive Plan. These studies and other relevant reports referenced below are available through the City of Iowa City. The Urban Renewal Plan, prepared by the Department of Community De- velopment in May, 1977 and the January, 1977 memorandum from con- sultants Zuchelli, Hunter & Associates on their market analysis of 12 DORM MICROLAB ;L';t- by JORM MICROLAb LLUAk kAVIJ'� AND A, Urban Renewal sites, were useful in planning for future commercial activity in Iowa City. The three-part Iowa River Corridor Study, 1975-76, prepared by Stanley Consultants, made several recommendations concerning the Iowa River and its floodplain. The majority of these recommendations have been incorporated into the Land Use Plan. Part I of the Veenstra & Kim Sanitary Sewerage System Plan, 1976-77, was used in determining population densities for areas within the city. The "Historic Structures Inventory" and the "Neighborhood Impacts Survey", both portions of the North Side Neighborhood Preservation Study were used in evaluating residential densities within the north side neighborhood. f;;..:;,1 :i. 1; BY JORM MICROLAB IV.

In addition, studies of the potentials and limitations of the natural and man-made environment, financial capabilities, and legal constraints were taken into consideration. A number of alternative courses of action were also evaluated. This section of the Plan identifies the overall goals for Iowa City as well as a number of functional goals for land use, transportation, economics, community facilities, housing and the environment. These goals represent the guiding principles of the Comprehensive Plan. Overall Goal It is the goal of Iowa City to protect the health, safety, and welfare of its residents; to allow for individual development and enjoyment; to protect and enhance the heritage and character of the city; to efficiently provide an adequate level of municipal services; to pro- tect the use, value, and enjoyment of private and public land; to protect and enhance the environmental quality of the city and its environs, and to wisely use and conserve energy. 14 IKRI-f ILFff :� B DORM MICROLAS ., �'J ;L by JURM MILRULAb Land Use Ul Aii kAPI'JJ Akb ui., . iL_ Goals 1.

Nearly all the factors which affect growth are inter -related. However, to provide clarity, the many considerations are divided into logical groupings as follows: Land Use, Transportation, Economics, Community Facilities, Housing, Environment, and Human Needs. Within the following sections, each functional topic is addressed. The key findings identified during the planning process are set forth. Explicit goals and objectives are identified, and a set of recommended policies is included in each functional section. These recommended policies link future decisions and actions to the goals and objectives which the City desires to achieve. A. LAND USE 1. Findings Analysis of existing land use patterns can provide much of the basis for a new land use plan. However, several factors besides existing land use influence the location of future land uses. These factors include soils, topography, dis- tance from established core areas, physical barriers, and the location of trafficways and utilities. A detailed dis- cussion of these topics can be found in the Locational is _ ;nruw uial,i Re JDRM MOCROLA13 ,._w)f ;G'., � by JOR14 141CROLAb LLDAt 1A'r1J'3 AnU L)L., U.'11 --"" Factors Report. The key factors regarding each of these topics are discussed below: a. Existing g Land Use A study of the existing land use in Iowa City was completed in 1976 and the results were published in the 1976 Land Use Summary. Careful consideration of the existing land use pattern serves to provide continuity and to protect private investment, the city's archi- tectural heritage, and existing neighborhoods. However, concern for increased environmental quality, efficiency, and fairness will require some adjustments to the established pattern. Some land use patterns are no longer valid as com- munity needs have changed. Land uses once well suited to a particular location may now be incompatible with surrounding uses or the sites may be more appropriate for another use entirely. Iowa City's existing land use is mapped in the 1976 Land Use Summary and a discussion of land use compatibility is contained in the Land Use Concepts Report, both of which are set forth in Appendix A. b. Soils Topography, and Vegetation Steep slopes and wet soils present limitations to urban development. Careful consideration must be given 19 DORM MICRmLAB ?,�. IL'dIa by JORM 141CROLAB CLUAR kAVIuS AND OL', 'ii,i:1L .n.', to the site planning process to minimize the development costs in these areas. Low coverage development is gen- erally best suited to areas of steep slopes or wet soils. The generalized development limitations imposed by soil and topography are set forth in the Land Forms Guide in Appendix A. Crop land and woodlands are two vegetation types which influence urban development patterns. The need to preserve areas of native vegetation, and to respect the productive role of prime agricultural land is well documented in the Vegetation Guide in Appendix A, and is discussed further in the Environment section of this document. In the coming years, as prime building sites within the city are filled, it can be expected that pressure for development in areas of steep slopes, wet soils, and woodlands will increase. Core areas are those locations where employment or shopping opportunities are concentrated. These areas are major determinants of traffic patterns, housing demand, and demand for other public services and facil- ities. In Iowa City, the existing core areas are: the central business district/east University of Iowa campus, the health center campus, the Mercy Hospital/Central Junior High School area, the intersection of Iowa "I(yol II.IdCJ 8v DORM MICROLA13 ,....or ;L`'.; z, by JOkM MICROLAb CJ CLOAti RAvIJ3 AND OLI 'ii;. IL . Highway 1 and Interstate 80 where American College Testing and Westinghouse Learning Corporation are located, the Lower Muscatine/First Avenue shopping area, the U.S. 6/Keokuk Street commercial area, the commercial area at the intersection of Iowa Highway 1, U.S. 6, and U.S. 218, and the southeast Industrial Park. These core areas are identified in the 1976 Land Use Summary and the Locational Factors Report and are discussed in the Locational Factors Report, in Appendix A. Trafficways Trafficways have a great effect upon city form and function. The relationship between trafficways and land use intensity is well established. Because of the need for ready access, intense land uses are generally located adjacent to major trafficways. As the level of access increases, land use intensity increases. Land uses which generate or attract large volumes of traffic are best located near the primary and secondary arterial system. Sites along the arterial system, with easy access to the external highway system, are sought for industrial and commercial uses which generate a signifi- cant number of semi -trailer truck trips. Major commer- cial centers which generate high volume automobile traffic also seek to locate along the arterial street system to increase accessibility and visibility. 21 DORM MICROLAS ',:_11,i I :L'Ii u IiY JURt4 MICROLAU e LEUAR RAPIJS MD OL'I 'r1,',1,, e" Physical Barriers Natural and man-made physical barriers influence the pattern of urban development by restricting utility extensions, and the vehicular and pedestrian transporta- tion networks. Several barriers exist within Iowa City including the Iowa River, railroad lines, limited -access highways, portions of the University of Iowa campus, and several large parks, cemeteries and school sites. In some instances these barriers provide desirable buf- fers. However, the existence and location of these Physical barriers has a direct impact on the location of land uses because the efficiency of utility exten- sions, population movement, and the provision of other community services is reduced when it is necessary to "go around" these barriers. f. Utilities Utility networks providing, sewer, water, electric, natural gas, and telephone service are essential for most urban land uses. The potentials and limitations which utilities (particularly sanitary sewers) present to urban development can be used in planning to identify areas of potential growth, areas which are at or near capacity, and areas difficult and inefficient to serve. 22 JORM MICROLA9 MICROLAb I,EUAR RAVIJi A;1D JL, -b .'r..,, �. The efficient provision of sanitary sewer service is closely related to watershed boundaries. Gravity flow sewers are most efficient in terms of capital cost and operating cost. The use of lift stations to pump sewage increases system operating costs and wastes energy. The new sewage treatment plant, which is programmed for construction immediately south of the existing city limits, will provide service to portions of the Willow, Ralston, Rapid and Snyder Creek watersheds. Certain areas within the city cannot be efficiently served by the sanitary sewer system. If developed, these areas should be in low intensity use such as low density resi- dential (less than one dwelling unit per acre) or ware- house. Land Use Compatibility Land use compatibility is based on the similarities or differences of the characteristics of land uses. Each land use type has specific site requirements in terms of topography, soils, access to transportation and utility networks, and lot size. Land use compatibility is also related to the levels and types of activity generated by a particular land use. Two bordering land uses with substantially dif- ferent activity characteristics are likely to be incom- patible. Incompatibilities arise over the side-effects 23 ..A 11 P1 III .1 !i, JORM MICROLA© ., ;. i:::.'; by JORM 1-11CkOLAB of the more intense land use which do not stop at property lines. However, in many instances it is desirable to locate incompatible uses in close proximity. In these situations careful site planning at the boundary between incompatible uses is necessary to assure that negative side-effects of the more intense land use are controlled. Architectural buffers (e.g., brick walls or wooden fences), or natural buffers (e.g., open space or natural screen- ing) may be useful in such situations. Where it is not desirable to locate incompatible uses in close proximity, two buffering techniques are particularly useful. First, transitions between different land uses which take place across alleys and rear property lines are usually more successful than transitions along side lot lines or across streets. Second, an intermediate use which shares some of the characteristics and requirements of the adjoining uses provides a less abrupt transition from high intensity to low intensity uses. These concepts are further discussed and illustrated in the Land Use Concepts Report in Appendix A. h. Energy Energy savings can be realized by distributing land use to maximize use of the existing utility net- works, streets, schools and other public buildings, and existing public services and facilities. Compact develop- ment of higher density residential and commercial develop- ment (as opposed to strip or spot development) will za JO R M MIC RO L A 6 r .L'1:o BY JURM MICkULAb i I,LUAJt iiJkPjjS AND OLS `�,,.": , . "" encourage pedestrian and bicycle travel, and the use of mass transit, and will reduce dependence on the private automobile. Future Land Use Future land use needs are based on projected demands of residents, business and industry, and government. The Report on Population: Summary provides information on existing and future population trends. It is expected that Iowa City will continue to grow by approximately 500 persons per year and that, as the University popu- lation stabilizes, the proportion of those over 25 and under 18 will increase. By providing adequate, yet not excessive land for business, industry, housing, and other activities, moderate growth can be accommodated, while the provision of utilities and other city services can occur in an efficient and economical manner. 2. GOALS AND OBJECTIVES - LAND USE a. Goals 1. To provide adequate development opportunities while recognizing environmental constraints and citizen needs, through a multi -core development pattern guided by watershed and other natural boundaries. 2.

LAND USE POLICIES The background topical reports in Appendix A, and the findings set forth above identify existing and predictable future problems. In order to achieve the land use goals and objectives stated above, the following policies should be established. Upon adoption of this Comprehensive Plan it shall be the policy of the City of Iowa City to: a. Existing Land Use 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 impera- tive to residents' health and safety. 27 sucau� mato i>� JORM MICROLA13 U. ;L:<i it BY JOHM MICROLAB LEUAR RAIU'; AND JL'a b. Soils, Topography, Vegetation 1. Utilize woodland areas, flood plains and creek head- waters as positive locational criteria for parks and open space, and similar low intensity land uses. 2. Encourage the use of Planned Unit Developments in areas where soils, topography, or vegetation are limiting factors. C. Core Areas 1. Locate new businesses, industries, health and education facilities in existing core areas where appropriate, to facilitate the provision of city services and maximize efficiency. 2. Provide higher density housing opportunities adjacent to core areas. d. Trafficways 1. Locate high intensity commercial and industrial land uses adjacent to major trafficways. 2. Locate moderate intensity land uses (such as multi- family residential or junior and senior high schools) in areas with direct access to collector or secondary arterial streets. 3. Locate low density residential uses along local streets. 28 :11 CRal 1 LM IJ 8e JORM MICROLA6 1.1,"'ru,:i.%!;., BY JORM 1.11CROLAB (_LOAR RAP IJ'� AND OL: 11):�I; . .,. e. Physical Barriers 1. Utilize streams, railroad lines, arterial streets and similar features to define residential neighbor- hoods for the provision of parks, schools, and other neighborhood -serving facilities. 2. Use ridge lines between watersheds to define the limits of urban development. 3. Utilize physical barriers such as parks and linear greenways as transitions or buffers between dif- ferent land uses. f. Utilities 1. Zone areas within the city which cannot be served by sanitary sewers for low intensity uses. 2. Discourage the use of sewage lift stations. 3. Discourage intense development which cannot be adequately served by existing or proposed City services and facilities. g. Land Use Compatibility 1. Where possible, zone to achieve gradual land use change. 2.

TRANSPORTATION 1. FINDINGS: a Transit The operation of a mass transit system offers Iowa City an energy efficient and environmentally sound way of utilizing its investment in streets and roadways. By using buses, the trip -carrying capacity of arterial streets is dramatically increased, and congestion is re- duced. Increased use of the transit system serves to alleviate parking problems in and near the downtown and other core areas. These problems also contribute to the deterioration of adjoining neighborhoods. Buses provide necessary transportation to low income residents, students, the elderly, and other Iowa City residents who do not have ready access to private trans- portation. Many of the sample and general survey re- spondents were highly complimentary toward the present transit system. Eighty-five percent of the People's Guide and Survey respondents would like to live within one to four blocks of a City bus stop. Buses are more energy efficient than automobiles, and efficiency can be increased as buses are more fully utilized. Currently, the transit system is under-utilized during the middle of the day and other off-peak hours, 31 DORM MICROLAB +.:�,'J ;L''II i BY JORM 1.11CROLAB and on outbound morning and inbound evening runs. Greater utilization of existing transit system capacity can be accomplished if major employers use flexible time or other adjustments to working hours. Additional transit efficiency can be gained by careful arrangement of the transit routes. b. Major Traffic Ways Numerous problems have been identified within the existing trafficways system of Iowa City. These include: congestion at river crossings; congestion and congested left -turning movements at major intersections; an inade- quate number of cross-town arterial streets; inadequate capacity on several arterial street sections; inefficient access to several core areas; and unnecessary traffic routed through the downtown core. An improved trafficway system would serve to benefit passenger and delivery vehicle operation, and the operation of the mass transit system. A more complete discussion of these findings is set forth in the Trafficways Report in Appendix A. C. Residential Neighborhood Impact The negative impacts of major trafficways upon resi- dential neighborhoods are, in certain locations, a major problem. During the citizen participation process, par- ticular concern was expressed by residents, both in 3? �����:AIC2iit IUdC.7 IIY JORM MICROLAF3 o ali r by JOkh1 1.11CkOLAb 0 UUAk RAF1U� A11U „Lq;,'IL_. . 111 surveys and in meetings, concerning high level of automobile and truck traffic operating through residential neighborhoods. These problems are caused by traffic "short -cutting" through residential neighborhoods on non -arterial streets, and by inadequate buffering between designated arterial streets and adjoining residences. Bikeways and Walkways Bikeways and walkways provide basic transportation and recreation to the community. As a form of transportation, bicycling and walking are much more energy efficient than driving a car. Additionally, they do not rely on dwindling supplies of fossil fuel power. Although the benefits of these energy efficient modes of travel are widely 'recognized, several constraints limit their full utilization. Conflicts with vehicular traffic make movement unsafe for pedestrian and bicyclists at many intersections and along several streets in Iowa City. The close - spaced grid pattern in the older areas of the community creates numerous conflicts between bicyclists and motorists. In new subdivisions, long curvilinear streets often have poor pedestrian and bicycle circulation characteristics. This topic is more fully discussed in the Trafficways amort and the Preliminary. Bikeways Plan. 33 �au ao� ivai , u� JORM MICROLA6 '- : 1C,!.0 by JURM 1.11CROLAb ULM kAPIU�l A11U JLC • '111' 2. GOALS AND OBJECTIVES - TRANSPORTATION a. Goals 1.

RECOMMENDATIONS The topical reports contained in Appendix A, and the summaries of findings contained above, identify existing and predictable transportation problems. In order to minimize these problems, and achieve the goals and objectives set forth above, the following recommended actions should be taken: a. Transit 1. Arrange routes so they end at employment centers when possible. 2. Provide higher level transit service in corridors where the higher level service will reduce traffic congestion by reducing the use of private automobiles. 3. Develop a program which will maximize the use of transit and reduce the needs for long-term parking in the downtown area. 4. As soon as ridership levels and financial capability permit, provide increased frequency and hours of service. 5.

ECONOMIC 1. FINDINGS: a Commercial Activity Market analyses indicate that upon completion of the Urban Renewal process, there will be adequate retail space in the downtown for meeting the City's needs. Required retail and office space was projected by consultants, Zuchelli, Hunter & Associates, Inc., as part of the Urban Renewal work program in January, 1977. The other major commercial areas in Iowa City, the Lower Muscatine/First Avenue shopping area, the U.S. 6/Keokuk Street commercial area, and the commercial area located near the intersection of U.S. 6, U.S. 218 and Highway 1, have been steadily expanding also. Ad- ditional information concerning commercial activity in Iowa City is contained in the Report on Economics in Appendix A, and in the Urban Renewal Plan and Urban Renewal LandMarketin Prospectus. b. Economic Development Because much of Iowa City's land is State-owned and non-taxable, Iowa City's tax burden rests more heav- ily on residential property. When compared to other cities of similar size, Iowa City has a larger proportion 39 JORM MICROLAB '•I: �..::ur .L'•i; a jsY JORM MICROLAB c. CLOAK kAkWS AMU )L- 10,iL .. of total property valuation in residential property, and a smaller proportion in industrial property. Enrollment projections for the University of Iowa, show a leveling off and actual decline after 1980. Not only will this affect the amount of retail trade in Iowa City; it may reduce new employment opportunities within the University. It is important, therefore, for Iowa City to reduce its economic dependence upon the University of Iowa by attracting new industries and other major employers. In mid -1977, the City Council began exploring economic development potential. The firm Zuchelli, Hunter & Associates, Inc., was retained to undertake a brief study of Iowa City's economic development poten- tial. An economic development program is to be established during fiscal year 1979. Most People's Guide and Survey respondents favored attracting University -oriented industry (83.6%), medically -oriented industry (83.4%) and other light industry (71.2%). Respondents emphasized that only non-polluting industries were favored. Neighborhood Commercial The use of neighborhood commercial centers to pro- vide many basic retail needs such as food, hardware, or pharmaceuticals, is an alternative to concentrating these retail activities in larger commercial centers. Convenience stores and offices in residential neighborhoods were favored by most People's Guide and Survey 40 _-�airuui u.ran� �s� DORM MICROLAB ..r .:_'!L , 11Y JUKM HICRULAb l,L'JAif RAFIJP ANU iiL� . • ^r' respondents (70.6%). Analysis of neighborhood com- mercial centers suggests that, if properly designed and regulated, these centers would not be disruptive and could be very beneficial by saving residents' time and energy. These stores significantly contribute to the reinforcement of a neighborhood concept within the city. The neighborhood concept is specifically addressed in the Land Use Concept Report in Appendix A. d. Energy The largest of Iowa City's care areas attracts as many as 10,000 employees per day. At present the majority of employees and shoppers travel to these core areas by automobile. When business and industrial activity are concentrated into cores, they are much more easily served by alternative transportation modes. Maximizing the population within walking or bicycling distance from shopping and employment opportunities will decrease de- pendency on the automobile. 2. GOALS AND OBJECTIVES - ECONOMIC a. Goals 1. To maintain the economic viability of Iowa City by ensuring sufficient employment opportunity and shop- ping facilities, and by expanding the tax base. 41 JORM MICROLAE3 1.1; .,60, IL:'!.0 BY JORI4 14ICROLAb 3 • CEOAR RAPIJS AND ,n, ._"", 2.

COMMUNITY FACILITIES In Iowa City, more than one governmental jurisdiction provides facilities for use by residents of Iowa City. Schools and parks, for example, are owned and operated by separate entities. Facilities operated by one jurisdiction could at times be utilized by another jurisdiction to great advantage. Additionally, because of many similar locational requirements, the joint development of schools and parks is frequently beneficial. 1. FINDINGS: a. Joint Facilities Benefits of joint development and use are evaluated in the Community Facilities Report in Appendix A. The joint development and use of community facilities offer greater return for the investment. Shared costs of structures and site development, and shared use allow for fuller utilization of facilities. For example, if properly designed, a school gymnasium can be open to the public for evening recreation. b. Parks Iowa City's park system consists of 28 parks totaling approximately 500 acres. The Community Facilities Report includes information on the type and location of each park, and at which parks recreation equipment and aS — sil�R���wata fr+ DORM MICROLAB o) . :',: BY JORM MICROLAB and areas are provided. The report includes national park development standards which, if applied to Iowa City would indicate a shortage of park land. However, Iowa City's needs for park land are somewhat unusual because of the University population and facilities, and because of the facilities provided at the Coralville Reservoir, Lake hlacbride and Kent Park. Of the People's Guide and Survey respondents, 59.6% felt additional recreational facilities should be funded. The Community Facilities Report and the Iona River Corridor Study (Stanley Consultants 1975-76) recommend incorporating into the parkland system areas of environmental concern, riverfront property, and flood detention sites. In the People's Guide and Survey, 62% of the respondents answered that improving the, Iowa River and riverbank should be a City -funded project. Linear parks, including bikewyas and walk- ways, provide improved access between facilities. As Iowa City continues to develop, new neighborhood and community parks will be necessary. In order to ensure the availability of parks in suitable locations to serve neighborhood needs, other communities require mandatory dedication of park land, or payments -in - lieu of dedication as residential land is developed. Iowa City could require mandatory dedication of park land or fees -in -lieu of dedication if certain standards are prescribed and met. 46 JORM MICROLA9 [V JURM 1.1ICkOLAb 117 2 ULUAK kAPIJi) AN6 ,Ju i;.-'iL.. Libraries and Cultural Activities For a community of its size, Iowa City has numerous cultural and learning opportunities in addition to the public school system. The Iowa City Public Library and Recreation Center are City -owned facilities; most others are part of the University of Iowa. The Iowa City Public Library is currently housed in a building with approximately 23,000 square feet of floor area. This facility is no longer capable of accommodating increased demand; additional space for shelving, staff and seating is needed. At present, the building is located on six levels and is inaccessible to the handicapped. Results from the People's Guide and Surve showed strong support (62.2%) for expanding library facilities. There was also citizen support for large and small meeting rooms and lounge areas for resting, reading, and socializing in the downtown area. Police and Fire Protection The Police Department has serious space deficiencies in its present facilities. The Police Department, which occupies a total of 5,426 square feet in the Civic Center, lacks interview rooms, adequate laboratory facilities, adequate storage space, sufficient booking and receiving area, and a private area for polygraph operations. Iowa City's Fire Department received a Class Four rating by the Insurance Services Offices of Iowa which compares very favorably with other Iowa communities. The only problem identified in the Community Facilities Report was inadequate apron area for the main fire station. 47 JORM MICROLAE3 '4; : L•I, J BY JURM MICRULAB LtUAR k0loJ) AND ULA .10i'L.. . " Iowa City now operates three fire stations: one centrally located, one to the southeast, and one to the west. As community growth continues, the City will need to continuously evaluate response time and equipment and man -power adequacy to ensure continued fire protection at the existing level. e. Energy Iowa City can assist residents in saving energy by locating public facilities at locations which minimize necessary travel. By providing neighborhood facilities (schools, parks, and recreation) within walking distance, the need for driving can be reduced substantially. Locating government offices compactly near the central business district will allow for better transit service and fewer trips. The construction, landscaping, and orientation of public facilities can serve as examples of energy ef- ficiency within the community. Presently, several private businesses in Iowa City accept items for recycling. The City is involved in recycling paper, and is experimenting with reclamation of bottles and cans. f. Iowa City Municipal Airport The Iowa City Municipal Airport occupies 485 acres in the southwest part of Iowa City. As explained in the Community_ Facilities Report in Appendix A, this airport is used extensively for general aviation. Federal Aviation Administration standards need to be 48 • ._ ;dl Lllnf �L11C i1 61' JORM MICROLAE] ,i::L:,:, by JORM 1.11CROLAb L�DAR RAI`LDJ AND A, 1,:.'u., used for the protection of the approach zones to the airport, and for protection of nearby residences. g. Public Offices The Johnson County. Regional Planning Commission conducted an evaluation of existing public and quasi - public facilities in 1975. The study found that in the Iowa City government facilities there is inadequate. space, buildings are not fully accessible to the handi- capped, locations are not convenient in relation to county offices, and Ralston Creek flooding poses a hazard to the Civic Center. The study also concluded that the Civic Center has several distinct locational advantages, including building expansion potential and publicly - owned land nearby. h. Utilities A discussion of the public utility systems in Iowa City is presented in the Report on Utilities in Appendix A. Areas which can be provided sewer service by the existing system are identified in this report. A new sewage treatment plant is included in the Capital Im- provements Program, and a site for the sewage treat- ment plant has tentatively been selected. Upon the completion of the new sewage treatment plant additional areas within the City can be sewered. However, construction 49 !.!I( P01 II.Mr a n, JORM MICROLAS ',:. i .L'1i.0 BY JOHM 1.11CROLAb 2 CEUAH k0ljJ ANU ,L� lo -'u. of a new sewage treatment plant will not fully resolve Iowa City's sewer system problems. Additional sewer system improvements will be required in the years ahead, in order to fully realize the potential offered by the new sewage treatment plant. The Iowa City water treatment plant capacity is more than adequate for meeting peak demands and should be capable of meeting future demands to the year 2000. The ability to efficiently provide utility service, particularly sanitary sewer service, is a primary de- terminant of future growth areas within the city. This is more fully explained in the Locational Factors Report in Appendix A and the Land Use section above. Specific sewer system improvements are addressed in the Growth Sequencing section of this Plan. GOALS AND OBJECTIVES - COMMUNITY FACILITIES a. Goals 1.

Select sites for future fire stations, prior to development, which will meet Insurance Services Offices of Iowa and location standards. e. Energy 1. Follow the recommended work program established by the Resource Conservation Commission to check existing public facilities for inefficient energy use, and make improvements where necessary. In constructing new facilities, emphasize energy- saving features in building, landscaping and site orientation. 2. Encourage and promote recycling efforts, and eval- uate energy efficient alternatives to the landfill. 3. Implement life cycle costing, where relevant, as a basis for capital acquisitions. 4. Check vehicle efficiencies and make improvements where necessary. In purchasing new vehicles, emphasize energy-saving features. f. Iowa City Municipal Airport 1. Follow FAA standards when allowing development to occur within airport approach zones. g. Public Offices 1. Prepare a study which evaluates alternatives for increasing office space. 54 DORM MICRmI—AB .,.,"i::,".; J by JURM MILRULAb LLDAtt kANI',1''j AIJU JLJ II.::,L . , 4 h 2. Provide reasonable improvements to make the Civic Center and other public facilities more accessible to the handicapped. Utility Service 1. Expand the sanitary sewer system in a manner which maximizes the use of gravity flow, and does not use sewage lift stations unless absolutely necessary. PUBLIC FACILITIES POLICIES In order to promote the purposes of this Plan and achieve the goals and objectives set forth above, upon the adoption of this Comprehensive Plan it shall be the policy of the City of Iowa City to: 1. 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. 2. Establish a system of bikeways and walkways in Iowa City. 3. Require mandatory park dedication or payment of fees - in -lieu of dedication as part of the subdivision process. 4. Locate neighborhood parks within walking distance of all residents living in areas where housing densities are greater than 2 dwelling units per acre. 5. Locate community parks so that recreation opportunities are available in all areas of the city. 55 DORM MICROLAB '•'�: i.i:U: :C;1iJ by JURM 141CROLAB • UUAR k0iuS AND AL "!�;j L., . 141' 91 7 11 Locate any new government offices central to the pop- ulation they serve, and preferably within an existing government complex.

LFuArt RAPIJ'� ApU OL'� I1.I-1L_. ds/Situation a City housing market is characterized by: ancy rates for rental housing; relatively costs; single-family dwellings which have ed to multi -family dwellings without ade- ions for parking and open space; and fairly development of apartments and single-family roughout the City. The Report on Housing zen Participation Report in Appendix A tional information on this topic. is of particular concern to city residents in the People's Guide and Survey responses )orhood meetings. All residents desire Ible housing. Single-family home owners •ceive the inclusion of rental or multi- •ties.in their neighborhoods as undesirable, ips frequently demand housing in the same area. Single -Family Dwellings itional single-family detached dwelling has itively expensive for many Iowa City 57 - IIICRoi ILIII I Its' JORM MICROLA6 �.W);.L'I;U by JURM MICROLAb I,LUAR RAI' 1J� AND A, 10:'n._, .!6, families and individuals. The supply of quality low cost single-family housing is limited. Current build- ing costs, and zoning and other development regulations contribute to the high cost of housing. The City can have a direct effect on the provision of low cost housing through zoning, and development reg- ulations. Garden homes, townhouses and mobile homes are three forms of single-family housing which could be encouraged. Garden homes are built on relatively narrow lots with one building wall located on one lot line with the other side yard at least ten feet in width. Because lots are smaller and utility and street improvements per lot are reduced, significant savings in land de- velopment costs can be realized. The traditional single-family neighborhood character is, however, retained. Townhouses are distinguished by common walls con- necting several individual units, and minimum lot sizes. Only end units have side yards, though all units have front and rear yards. Townhouses represent the maximum density for single-family housing. Land development costs are minimized and building costs are reduced (due to common walls). Garden homes and townhouses are further discussed in the Report on Housing in Appendix A. Mobile homes are the form of single-family hous- ing with lowest costs. Mobile home owners would like the choice of purchasing their lots in a mobile home sub- division or renting their lots in a mobile home park. 58 ;-I1(1?01 IIIli ) R) JORM MICROLAB ,,,,;r :, -11?. by JORM 1-11LkOLAd c rol I_LJA,f kAPI05 AlIU ,ILS I,,: Vii;_. . ,. Housing for Special Groups Housing for the handicapped, the elderly, students, and other special groups is necessary within any com- munity. The State of Iowa requires that apartment com- plexes with more than four units have one or more units which are accessible to the handicapped (a sliding scale is used). Subsidized elderly housing will be signifi- cantly increased in the near future with the construction of two new complexes within and adjacent to the downtown. Approximately 47% of the University of Iowa student population is housed in dormitories, married student housing, fraternities, or sororities. The rest must find housing elsewhere. This has created a high demand for low cost rental housing near the University campus. Housing Location A number of factors influence housing location, in- cluding: distance to core areas (areas where employment, education, or.shopping opportunities are concentrated); availability of city services such as sanitary sewer, water, schools, and parks; location of hazards or nuisances such as highways, railroads, heavy industry, or extraction operations; and environmental factors such as floodplains, valuable agricultural land, topog- raphy and vegetation. Generally, the highest density 59 JoRM MICR©LAB ;LX , by JORM MICkOLAb CEDAR kAkIJ'� AtJU Uu • housing is best located adjacent to core areas, where adequate city facilities and services exist, and on areas of relatively flat topography. Low density hous- ing is suited to all types of topography, and requires the provision of less intense city facilities and services. Residents of low density housing generally prefer to be away from core areas. All housing should be some distance from hazards and buffered from nuisances. Though there has been a consistently high demand for low cost housing near the University, other renters prefer different locations. This is not to imply that multi -family units should be mixed with single-family. Instead, multi -family units can be successfully inte- grated in neighborhoods as transitional uses between neighborhood commercial areas and single-family resi- dences. e. Housing Rehabilitation Housing rehabilitation maximizes the potential use of the existing housing stock (often resulting in low cost housing), serves to maintain the character and function of existing neighborhoods, and frequently serves to preserve the city's architectural heritage. However, older homes may be quite expensive to heat due to size or construction, or may be located in areas no longer suitable for single-family housing. In some 60 DORM MICROLAB �; ;L'ILJ EY JORM 1.11CkOLAb f (,LUAR RAPIJ3 AIIU uU �' "I , instances, these homes may be moved to new locations or converted to multi -family residences. Neighborhood Preservation The preservation of Iowa City's older neighborhoods is of major concern to some residents. The homes in these neighborhoods, some of which are architecturally and/or historically significant, have contributed much to the city's character. Many of the homes have been converted into multi -family units or torn down and replaced by apartments. Scattered apartments within established neighbor- hoods tend to disrupt activity patterns and weaken neighborhood identity. In addition, existing City facilities may be inadequately sized to efficiently meet the needs of multi -family use. Some homes will deteriorate to the extent that it is no longer economical or practical to retain them; other homes may be destroyed by fire or similar disaster. Garden homes and townhouses, as replacement for groups of single-family houses, provide economical alterna- tives for retaining the single-family character of a neighborhood. Housing and Site Design Criteria and Energy Conservation Good housing design is a benefit to the community 61 _ _sno!uiiiwn�ur JORM MICROLAEI '!:-1,01 :L I a by JORM h11CkOLAB N (LUAk RAP IU5 4D Jt, 1GJ,L., -"` in general. Not only does it help people to live com- fortably and in a pleasant environment, but it can also help to reduce housing deterioration, energy waste, and psychological stress. Privacy is essential to good housing design and was expressed as second only to cost in satisfying hous- ing needs of the respondents to the People's Guide and Survey. Noise buffering between attached residential units, and fencing of yards are two common methods of increasing privacy in residential areas. Proper site orientation not only increases privacy but also conserves energy. The addition of landscaping can further decrease energy needs by providing shade in summer and insulation in winter. The Vegetation Guide in Appendix A provides additional information on the benefits of urban vegetation. Enjoyable private open spaces for each dwelling are energy efficient because they reduce the need for leisure auto trips. Most multi -family units are lack- ing in open space and other amenities.

F. ENVIRONMENT I. FINDINGS: a Fragile Environmental Features Iowa City has a number of natural features which are environmental, aesthetic and recreational assets to the city. These features include the Iowa River, bottomland woods along the streams, and steep wooded slopes, all of which provide environmental variety. Upland woods, as- sociated with steep slopes, provide opportunities for parks, conservation and very low density residential uses. The Storm Water Management, Flood Plain, and Tree Ordin- ances are means of protecting these features. Conserva- tion of natural areas was viewed as the highest priority item by citizens responding to the People's Guide and Survey (85%). Seventy-three percent of those stating that conservation of natural areas should be funded were also willing to pay more for existing services in order to fund such projects. The ecological importance of maintaining a diversity of natural systems, which provide for a large variety of plant and animal life, is explained in the Vegetation Guide, in Appendix A. GR A ( RM ILIdf d 61' JoRM MOCROLA13 L',,; by JORbt MICROLAb CLGA,< kAPIij AIIU ,L� ;, , �t . b. Natural Stream Corridors The flooding of Ralston Creek has been a serious problem in Iowa City for a number of years. As develop- ment takes place within the watershed, the additional impervious surface area increases run-off and compounds the flooding problem. Flooding is a potential hazard as development occurs in other watersheds, also. The stream channels form natural corridors which, if left as greenbelts, serve to reduce the effect of heavy run- off from adjacent development by maintaining the natural floodway and flood plain to transport and hold water. Vegetation on the banks of stream channels minimizes erosion, and varying soil types permit diverse vegeta- tion and wildlife habitats. Bottomland woods, associated with stream valleys, are well suited for development of linear greenways through the city and as storm water detention facilities. In addition, construction in the flood plains is costly, making flood plain land more suitable for low intensity uses. C. Soils and Topography The Landforms Guide details the variety of soil types in Iowa City, Soil requirements vary for different land uses; poorly drained soils with high moisture re- tention are unsuitable for intensive land uses but can be used for low density development. Similarly, steep 69 fir. POO IIP,{ I IPS. DORM MICROLA6 ti(u�;L�'% J [iY JURM MICRULAB I,LDAR kAVIJ� ANU LJL slopes create construction difficulties and erosion hazards. Details concerning these factors in Iowa City are contained in the Landforms Guide and Locational Factors Report, in Appendix A. d. Edge Effect of Open Space Urban land uses - especially continuous, contiguous development - create large tracts of land devoid of both diversity and the natural systems necessary for a healthy, stable environment. The result is pollution, psychological stress and a degraded environment. The Johnson County Regional Planning Commission's Land Use Plan for the Metropolitan Portion of Johnson County, Goals and Objectives for Parks, Recreation and Open Space (1976 Update) recommends a system of greenways connecting neighborhoods to schools and open space, and a linked network of open spaces along the Iowa River and other stream corridors. Parks, recreational areas, and open spaces which are located so that their expos- ure to public activity is maximized offer the greatest number of benefits to the public. Linear parks or greenways provide for a very large area of contact be- tween open space and urban uses and therefore have a great edge effect. When these facilities border streets, They provide relief from continuous urban development, and expand the natural effect at transitions between 70 __.. A H Rol ❑.1111 BY JORM MICROLAB ";;_-�& ;,'t; , BY JORM 01CROLAB LEUAR RAYIU�) AkU L '.;,'i... open space and other uses. These benefits are greater per unit area of open space when open space areas are linear and have irregular boundaries. In addition, a linear park or greenway provides a buffer between land uses on each side. This buffer provides not only visual relief but also reduces noise and air pollution. e. Urban Quality 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. In both the Special Surve and the People's Guide and Survey, many residents expressed concerns about increasing pollution particularly of the creeks and the Iowa River. The main sources of pollution of the Iowa River are run- off from fields and feed lots upstream, dust and rock particles from extraction sites, inadequate sewage treatment facilities and solids from the water treatment plant. Run-off from trafficways and, in winter, salt from the streets also contribute to pollution. In- creased storm water run-off due to urbanization con- tributes to the inadequacy of the sewage treatment plant. The effluent from this plant does not meet EPA standards (See Sanitary Sewerage System Facility Plan, Pt. I, Veenstra & Kimm). 71 ........11c@ul II.I1I ''1 a1' DORM MICROLAEI u:L; i a BY JURM 141CROLAG f LEDAR kAPIUJ ANu IL, 'I,,."L . . A` Air pollution in Iowa City is caused mainly by auto- mobiles, trucks, and coal burning systems. Noise pollution in Iowa City is caused mainly by motorized vehicles and machinery. The effective noise level increases with the decrease in buffering vegeta- tion. As shown in the Tree Plantinq Plan, trees ef- fectively reduce sound levels by blocking, reflecting and absorbing sound waves. All types of vegetation also reduce air pollution by absorbing gaseous pollutants and mechanically filtering dust particles. (See Ecological, Environmental and Engineering Use of Trees.) The response to the Pile's Guide and Survey was strongly in favor of energy conservation measures. Eighty-six percent of the respondents said the City should enact energy-efficient construction requirements, 69% wanted the city to support home insulation programs, and 57% indicated an interest in installing solar heating and cooling systems in their houses if low interest loans were available. 91% supported recycling programs which conserve energy and reduce litter. The increased use of mass transit and bicycles for energy conservation and to help reduce air pollution was also supported. 72 JoRM MICROLAB . i; ._`%,; by JOKM MICkOLAb EA L'LuAr� kAkWj ,AILD OL, �.- .. The amount of solar energy available for daily use is over 10,000 times the amount of fossil fuel energy we currently use on earth. By development and wide appli- cation of new solar technology, we can not only assure ourselves a reliable source of power, but we can more closely fit into natural energy processes and reduce pollution. There are also other sources of energy such as wind, hydro -electric, and methane gas produced by burning trash, which can reduce the need for fossil fuels. The cycle of solar energy use is described in Ecological, Environmental and Engineering Uses of Trees: Energy Conservation which is available from the Iowa City Department of Community Development. Appropriate site orientation and landscaping can be used to conserve energy in buildings as described in the Tree Planting Plan. GOALS AND OBJECTIVES - ENVIRONMENT a. Goals 1. To provide a stable and healthful urban environment for all residents, which is in harmony with the surrounding natural and agricultural environments. 2. To preserve and protect fragile environmental areas. 3. To maximize the impact and accessibility of parks and open spaces for all residents. 73 DORM MICROLAS . •. u .

The Human Needs Plan will be completed in the fall of 1978 and will be adopted as a separate Comprehensive Plan element at that "t: i. it li ;LYnL BY JORM MICROLAB CLDAk RAPIU� AND A 4i !It.. , v" VI. EXPLANATION OF THE MAP The overriding concept in preparing the new Iowa City Land Use Map has been to encourage compact development within portions of the Willow, Ralston, Rapid and Snyder Creek Watersheds. These areas can be efficiently and economically served by the proposed sewage treat- ment plant, and other city services and facilities (existing or pro- posed). In addition, the provision of parks and open space, including linear greenways, and the allocation of development intensities will serve to protect the environmental quality and to assure a healthful environment. The area of the Map within the dotted line is the focus of this Plan. This area, if fully developed and redeveloped, could represent a total population of 95,000, which would be an increase of 45,000 over present population. This amount of growth is not expected to take place within twenty (20) years (projections suggest the growth of 500 persons per year should be expected). Areas of increased densities are not likely to be developed or redeveloped completely within a twenty (20) year time frame. Consequently, many areas will be lower in density during the twenty (20) year period then the Map indicates. Meanwhile, undeveloped areas will provide greater location opportunities for developers and home -buyers. The accompanying sequencing map is based on the cost of providing trunk sewers to potential development areas. The order in which water and sewer service is extended to parts of the city will direct the sequencing of growth and development. Included in Appendix B are the m :11(IN11 IL6¶rI BY JOF7M MICROLA6 ,,, I: „'% L, by JURM MICRULAS LLJ;k HAPIU'� AU ,L� '';1;."L , expected population increases for various areas of the city, and descript- ions of the proposed facility sites to serve the new population. The Land Use Map emphasizes development capability. The capability is determined by the ability to provide utilities, by environmental factors, and by existing uses. The ability to provide sanitary sewers is an im- portant factor in determining residential density for the areas within the city. There are some areas on the far west side (west of Mormon Trek Boule- vard and south of Melrose Avenoe) where the ability to provide sanitary sewer service with existing facilities is questionable. A study by the Public Works Department, now underway, will determine the existing capacity and provide recommendations for serving this area. Areas of steep slopes, flood plains or significant vegetation are designated for low intensity use, or as open space. High intensity uses (i.e., commercial and indus- trial) are located on major streets and near existing core areas. Where possible, low density residential uses are located away from heavily traveled streets, industry and commercial activities to minimize conflicts. Some of the locations for recommended use on the map are approxi- mate; circles and rounded edges are meant to imply that boundaries and locations are not definite for neighborhood commercial areas, parks or park/school sites. A set of locational criteria is provided else- where in the text to define appropriate locations for these flexible land uses. The Land Use Map indicates generalized land uses. In the downtown area, individual sites for different uses have not been specifically identified. Each category of land use on this map may include up to four zones on the zoning map. In a single category for residential Ff :11(Rol It till) m}' JoRM MICROLAB 141,�r1,)I IL. -4,, by JORM MICROLAb Li OAR kANIUS AIN) ,,u . . 1.1 use, there may eventually be zoning for townhouses, duplexes, four- plexes, small apartment buildings and mobile homes. These categories have been designed to portray intensity and density rather than specific use. Further discussion of the land use categories and locations follows. RESIDENTIAL The Land Use Plan generally preserves existing residential uses while providing greater opportunity for high density housing close to the University of Iowa and alternative forms of single-family dwellings throughout the city. The majority of land designated for housing is for single-family use, in keeping with existing de- mand. This Land Use Plan fulfills the housing objectives of Ions City. Efficiency is maximized, variety of choice is offered, de- velopment alternatives are maximized, and low cost housing is encouraged. 25+ Dwelling Units Per Acre Highest density housing opportunity (25+ DU/A) is pro- vided north and south of the Central Business District (CBD), adjacent to the eastern edge of the University of Iowa campus, and between Newton Road and U.S. 6/218. The University of Iowa, Veterans and University Hospitals, and the CBD are the largest core areas in terms of employees, students, patients, and shoppers. Locating high density housing in these areas RN :I IL It III I LI IIO R1' JORM MICRmLA6 ,,. ,,I; .I % , JY JORM MICkOLAb LLUAk KAPI,iS 4NU ,,L would be convenient for residents, and would increase ef- ficiency and energy savings by encouraging pedestrians and shortening travel distances between places of employment, classes and residences. City services and utilities can be adequately provided and the areas are located adjacent to arterial or collector streets. Limited commercial activity will be permitted in some areas within this use category. 16-24 Dwelling Units Per Acre Moderately high density housing opportunity (16-24 DU/A) is provided east of the CBD, in the Benton Street/Green- wood Drive area, north of Towncrest, along North Dodge Street and in several other locations generally along col- lector or arterial streets. This land use density includes townhouses, low-rise apartments (three stories or less), and mobile home parks and serves as a transitional use between high density housing and/or commercial areas, and moderate density housing (garden homes, townhouses and mobile home subdivisions). These areas are located near core areas to encourage economical redevelopment in some cases, or to provide choice for renters. 8-16 Dwelling Units Per Acre This land use area is the highest density single-family category and also includes low density multi -family uses. Garden home, townhouse, and mobile home subdivisions and parks are the principal forms of development. These uses are located in several areas throughout the city, but 9K -tairuunumu ir, JORM MICROLA6 L'h , BP JORM MICkOLAB CEUAH kAPIUS AHO OL, ,;!�,.'iL-, . are generally closer to core areas than the 2-8 DU/A density. Residential development of 8-16 DU/A is also used as a tran- sitional use between apartments and low density single-family housing. These areas are located to encourage economical development or redevelopment of single-family neighborhoods, to provide choice for home -buyers, and to allow mobile home subdivisions. Planned Unit Developments in this use category provide opportunity for the inclusion of traditional single- family detached dwellings, and apartments if the overall density is maintained. 2-8 Dwelling Units Per Acre Land use density of 2-8 dwelling units per acre includes traditional detached single-family dwellings and garden homes. Areas of this density are provided throughout the city, gen- erally away from commercial and industrial areas, and major trafficways. Buffers, indicated by green strips, are shown where these residential areas and incompatible uses adjoin. The use of Planned Unit Developments in this use category can provide opportunity for the inclusion of townhouses and apartments if the overall density is maintained. Less Than 1 Dwelling Unit Per Acre Very low density housing opportunity (less than 1 DU/A) is provided in the area north of 1-80 and in the area south M <ir.u�ri �Lwc� iIv JORM MICR6LA13 by JOkH Id 1CROLAb LL'uAr� r<APIU'� ANu )�� ,,: u . of Ralston Creek, east of Scott Boulevard. These areas can- not be efficiently served by sanitary sewers. Existing woodlands provide an attractive setting for residential dwellings. This area provides housing opportunity for those who might otherwise choose to locate in rural areas of the county. Agricultural land will be saved and potential in- terruption of farming operations minimized. The size of individual lots will depend upon soil type as the dwelling units will require on-site sewage disposal systems. The cost of providing police and fire protection and road main- tenance to this area will be higher than average. Land Use Intent for Special Areas Because the Comprehensive Plan Land Use Map is generalized and certain land uses may include a number of different zones, specific use is recommended for certain special neigh- borhoods of Iowa City. Reasons for these recommendations are given in detail here, so that future Planning and Zoning Commissions and City Councils will have a record of the intent of the present City Council when this Comprehensive Plan was adopted. I. Advanced Drainage Systems Site This area bounded approximately by Sheridan Avenue, the railroad, Maggard Street and Ralston Creek is shown at a residential density of 8-16 DU/A (dwellings units per acre) 85 __- AhRuiILIIf RY JoRM MICROLA6 ,,'6)' I,-!I � by JORM MICROLAb I.CDAk RAPIJ) AND A it .:IL , . 11- on on the Land Use Map. The site is almost entirely surrounded by single family dwellings with a gross density of about 5 DU/A. (The net density is approximately 7 DU/A.) Because of the lot size of most of the units, the area surrounding the ADS site will mostly be zoned for a density of 8 DU/A (the land use map shows possible zoning for 2, 5, or 8 DU/A). The Advanced DRainage System site will also be zoned at 8 DU/A, however, because this site is particularly well suited for cluster housing (which could reduce the impact of the railroad and the Ralston Creek flood plain), it has been shown as 8-16 DU/A on the Land Use Map. This will make subdivision and development of the area more economical- ly desirable, since up to 60 units could be built on the site, and indicates that use, while remaining single-family residential, will not be traditional detached single family houses. II. hlacbride Addition Part II This subdivision which is bounded by Melrose Avenue to the north and Mormon Trek Boulevard to the west is cur- rently zoned as a Planned Unit Development (PUD) within the RJB zone. Most of the single-family houses in this development have been built, but 104 apartment units planned for the corner of Mormon Trek Boulevard and Melrose Avenue have not been constructed. The land use map indi- cates the whole subdivision at 2-8 DU/A, and, whereas this overall density would be maintained when the apartments are built, the net density of that particular area will be higher. 86 :dlGk�il 11.IIrD BY JORM MICROLAB ',,; r;); .L"!I,BY JURM MICkOLAb III. "Encllert" Tract LEUM kAVIJ'j AtIU ,u '�".',L , This area bounded approximately by Taft Speedway, N. Dubuque Street and Foster Road contributes to the at- tractive, open north entrance to Iowa City. The City is unable to purchase this tract for open space at this time. The tract is almost entirely in the flood plain and is therefore shown for development as cluster housing at 8-16 DU/A. The intent is to permit economical development while maintaining as much open space as possible. Recom- mended zoning will be at a density of 8 DU/A. PUBLIC/SEMI-PUBLIC Parks and Open Space Parks and open space are an integral part of this Land Use Plan. These areas are generally located in woodlands, along streams, or along ridgetops. These areas provide linear greenways throughout the city (generally along streams), visual relief to intensely developed urban areas, opportunity for outdoor recreation and education, wildlife habitat, and similar land use opportunities. Park and open space areas may be publicly or privately owned. However, the majority of these areas shown on the map are or will be in public or semi-public use. Examples of privately owned open space include: country clubs, golf courses, and common open space in Planned Unit Developments. LII .. .. ...:n 1 Ri d 1 Olfa [I DORM MICROLAB I.!.. L"t..l; :L�11.G BY JORM MICkOLAB LLUAit MPiJS AIw JL, >k Parkland is provided at the ratio of twelve acres per 1,000 population and is divided among several categories of parkland. Four types of parks are recognized: playgrounds, neighborhood parks, community parks, and city-wide parks. Standards for these parks are described in detail in the Comnunit Facilities Report. Generally, five acres per 1,000 population have been allocated to playgrounds or neighborhood parks, and seven acres per 1,000 population have been allocated to community or city-wide parks. New parks are represented on the map by dots (see legend). The size of the dot ap- proximates the size of the park. The majority of existing city residents are within one- fourth mile of some type of park or school playground. Large lot single-family residents have less need for play areas within walking distance. In high density residential de- velopments where adequate yard areas do not exist, the need for neighborhood parks nearby is greatest. Another factor which affects park land distribution is accessibility. Heavily travelled streets and highways, rail- roads, streams and similar barriers can limit the area con- sidered "within walking distance". Parks are generally located away from heavily travelled streets, highways, and intersections. However, parks should be designed to maximize exposure to collector or local streets. In this way, the greatest number of residents can enjoy the open space pro- vided, as the park is visible to all who go by. Parks which border rear lot lines of residences are undesirable as they provide the open space benefits to relatively few.

Along streams, the greenways will vary in width depending on flood plain size. New parks and school sites are located adjacent to greenways wherever possible. These greenways provide natural corridors within the city and opportunities for walkways and bikeways. Neighborhood parks are located and sized in conjunction with population distribution. Three new neighborhood parks are proposed in or immediately adjacent to existing residential areas where it has been determined that deficiencies exist. Existing city-wide and community parkland is adequate for a population of approximately 55,000 people. An ad- ditional 315 acres will be needed for the potential 45,000 population shown on the map. The 270 acre community/city- wide park shown on both sides of the Iowa River (southeast of the airport) in accordance with the recommendations of the Iowa River Corridor study by Stanley Consultants, a 40 acre park along the Iowa River on the peninsula (op- posite the old Coralville Power Dam), and an addition to Hickory Hill Park will provide adequate additional community and city-wide parkland. The designation of park/school sites is intended to provide the public school system with suitable locations for potential elementary and junior high schools. Projected population figures and the assumption that elementary schools should generally be centrally located in relationship to their service population, were utilized to determine appropriate general locations. Elm JORM MICROLAEI uI iiY JORM MICROLAB U,)Ak kAP W� AtIU OL , ,;_ , ..v... School/park sites are dependent upon population distribu- tion. Generally, elementary schools are located to serve neighborhood units of approximately 6,000 persons and are on local streets. Junior highs are located to serve a number of neighborhoods and are generally on collector or arterial streets. The park/school sites will remain as open space until development occurs. Park development will generally occur concurrent with development of the area; schools will be built when and if they are needed. The sites will be sized so that adequate parkland will remain if the schools are built. This implies that excess parkland will be held for some time; it should be considered an economical alternative to a limited or non-existent choice of school sites at a future date. If a site is not needed for a school, it may be utilized for another public facility such as a fire station. Elementary school/park sites are located: on the penin- sula; along Willow Creek south of Benton; along Willow Creek west of West High School; west of Wetherby Park; east of the proposed sewage treatment plant; southwest of Bon -Aire Mobile Home Park; and north of Hickory Hill Park (along the exten- sion of First Avenue north). The southwest intersection of Rohret Road and Mormon Trek Boulevard, and an area between Hickory Hill Park and A.C.T. are potential junior high school sites. Each junior high site is approximately 40 acres in size. Additional acreage for parkland is not needed at the Hickory Hill junior high site as the park and school site will be linked with a IO DORM MICROLA6 _,a& ;:'!; bV JORM M[CROLAb CLDA,t kAP:J, ANO A, �, . il greenway; five to ten acres of neighborhood park will be necessary at the Rohret Road junior high site to serve the surrounding neighborhood. Public and Semi -Public Buildings Existing public and semi-public buildings shown include: government offices and buildings, the Recreation Center, Veterans and Mercy Hospitals, and the National Guard Armory (public and private schools, and the University of Iowa are not included in this category). Due to the general nature of this map, the City Library, the existing sewage treatment plant, churches, and private clubs are not shown. New public and semi-public facilities will include a City Library in the Central Business District, an east side fire station/water storage tank on Rochester Avenue, and a new sewage treatment plant on South Gilbert Street. Other new uses may include private clubs, government office and facility expansion, and churches. New government and semi- public facilities will be appropriately located to conform with standards set forth in the Zoning Ordinance. University of Iowa All properties under the control of the Board of Regents of the University of Iowa are included in this category. 91 .�—ncuu�ivain iiv JoRM MICROLAB :Lil; i BY JORM VIICRULAB AGRICULTURE LLDAR kAPIuS AIU OL, 11-11 The areas depicted as agriculture on the map are to remain as such for years to come. The preservation of prime agricultural land south and east of the city limits is consistent with National, State, and County government policy. In some instances, however, fiscal considerations may dictate development of limited areas of prime agricultural land which can be efficiently provided with municipal services. In areas shown as Agriculture on the Land Use Map, residential development at a density of one dwelling per acre or less may be permitted where the land is unsuitable for agriculture. COMMERCIAL Neighborhood Commercial The majority of new commercial areas will be neighbor- hood commercial centers. The locations shown on the map are approximate. These centers are located on one corner of the intersection of two arterial streets or the intersection of an arterial and a collector street. The size, number, and types of retail establishments included in the center will depend on the size and type of population to be served. The centers shown on the map would eventually serve around 8,000 to 10,000 neighborhood residents. A grocery and drug store would generally be the main tenants of a neighborhood center. (Single stores or very small centers could be included in Planned Unit Developments, but are not shown on the map.)

Gross floor area could range from 30,000 to 75,000 square feet. Standards for location, design and hours of operation of these stores are included in the Zoning Ordinance. These standards are designed to protect neighboring uses from potential conflicts. General Commercial General commercial use is provided in existing core areas and in one or two other locations. The number of commercial areas is limited to maximize efficiency and to minimize impact on residential neighborhoods. Department stores, apparel and accessory shops, office supplies, res- taurants, and similar retail operations are examples of general commercial activities. Adequate opportunity for ad- ditional general commercial development exists within these areas. The majority of new general commercial development will occur in the Central Business District as a result of recent urban renewal activity. Several new stores, a hotel, and office space will be added. Additional commercial expansion may occur south of the U.S. 6/Keokuk Street commercial area, northeast of the Lower Muscatine/First Avenue commercial area, and between South Riverside Drive and the Iowa River north of U.S. 6. 93 ;niemu.iu, B JORM MICR6LA6 I; ;; ''; ; by JURM MICRULAb Office commercial LEUAP kAPIJJ ANU JL� ..'11. , Office commercial used include professional offices such as doctors, dentists, and lawyers. The greatest demand for additional office space is in the Central Business District and adjacent to Mercy Hospital. Office space in the CBD can occur in conjunction with the general commercial area. New areas for office space in the area surrounding Mercy Hospital have been indicated. A four square block area east of the City Civic Center/Recreation Center complex has been designated for office use, as has an area near the Highway 1/Interstate 80 interchange. Small additional amounts of office space may occur in neighborhood commercial areas or other general commercial areas. Land Consumptive Commercial (Warehouse)_ Land consumptive commercial use includes wholesale or retail businesses which require large amounts of land. Auto dealerships, construction yards, and building suppliers are examples of this type of use. The land designated east of the Iowa River provides opportunities for expansion. The area southwest of the airport along Highway 1 and U.S. 218 provide the greatest area for potential land consumptive commercial development. Access roads will be constructed along Highway 1 and U.S. 218 as needed. Expansion of highway commercial uses (motels/hotels, res- taurants, and a gas station) will be limited to one quadrant of the Highway 1 -relocated U.S. 218 interchange. 94 JORM MICROLAB ..

These sites provide excellent access to the Interstate system, as well as the potential for attractively landscaped settings. Uses in the office research parks could include national or regional offices in addition to research facilities such as A.C.T. and Westinghouse. Manufacturing Manufacturing uses may locate in the southeast Industrial Park on U.S. 6, and on the east side of U.S. 218 southeast of the airport. Access to the transportation network is adequate in these areas; however, the improvement of Scott Boulevard will increase the attractiveness of the Southeast Industrial Park for potential industries. The new sanitary sewage treatment plant will also serve to increase the potential for manufacturing expansion. Performance standards are included in various State and City ordinances to regulate industrial pollution and to minimize impact on adjoining non -industrial uses. Additional areas for industrial development may be needed as new industries locate in Iowa City. The following 95 k0f ilMf'] io JORM MICROLA© BY JURM MICkULAB l,LUAIt RAVIJ'� AkU ,nI i,,I'IL-. areas are commended as suitable for industrial or light industrial land use at such a time as more land is needed for these uses: 1.

The western bypass is located some distance to the west of the 20 -year growth line in order to preserve the develop- ment potential of the Willow Creek watershed. The development of an eastern bypass in addition to Scott Boulevard is important as a means of improving access to the Southeast Industrial Park ark area, and as a means of minimizing the intrusion of truck traffic in reasidential areas. The eastern bypass is located one mile east of Scott Boulevard on what is now a county road. Curving to the west, this bypass intersects U.S. 6 at the U.S. 6/Scott Boulevard intersection. The bypass continues southwest and joins the proposed southern bypass about one mile east of the Iowa River. The southern bypass will extend east from the intersection of relocated U.S. 218 and existing U.S. 218 South approximately one mile south of the existing City limits. Construction of a new Iowa River bridge will be necessary. This completed bypass system will provide alternative routes to through traffic, considerably reducing traffic congestion and disruption on City streets. The purpose of the central arterial system is to provide ef- ficient traffic flow through various parts of the city with emphasis on the University, the hospitals, and the downtown areas. Because the expansion of street capacities tends to disrupt neighborhoods, street widenings have been recommended only where existing problems seriously impede the flow of traffic. Construction of new arterials is recommended only for peripheral locations. 97 B JORM MICROLAB I): ,L'�.; c by JOR14 MICkOLAU CLUAk kAklu� Aro AL !I : a , - 41 0 Several streets on the west side will be improved to primary or secondary arterial standards. Melrose Avenue will be improved from relocated U.S. 218 to West High School. Portions of Mormon Trek Boulevard will be upgraded as necessary to carry arterial traffic from First Avenue in Coralville southward. Expansion of Sunset Street from Benton Street south to Highway 1 is also shown, and Camp Cardinal Road and Rohret Road are shown as secondary arterials. On'the east side of the Iowa River, a minimal widening of Dubuque Street from Park Road to Church Street will ease congestion and provide a more even flow of traffic to and from the central business district and central campus. Improvement of North Dodge Street from Prairie du Chien Road to Interstate 80 will also facilitate traffic flow to and from the downtown area. Improvement of South Gilbert Street is shown south of U.S. 6. Other improvements are shown where it is anticipated that future traffic volumes will warrant system changes. An extension of First Avenue north and west to link with Foster Road will serve as an alternate route through the northern portion of the city. Improvements to Scott Boulevard and Rochester Avenue east of Scott Boulevard will serve as east -side arterial streets. Though the city's commitment to mass transit cannot be graphically displayed, an efficient arterial system is basic to an efficient mass transit system.

DEVELOPMENT SEQUENCE UUA� iOPiJz) AU OL '':.':L In order to efficiently provide governmental services and facilities, and to minimize development costs, a sequence of development is estab- lished by this Plan. The principal elements which have determined this sequencing pattern include the phased extension of arterial streets, sanitary sewers, and water mains. Existing capacities of the above- mentioned systems also exert considerable influence on the sequencing of development. The ability to provide adequate levels of police and fire protection, and transit service are also instrumental in the development sequencing pattern. Specific discussion of these factors is set forth below: A. EXISTING SEWER CAPACITY The Report on Utilities and the Locational Factors Report identify the existing sewer capacity. Within the established portion of the city, there is sewer capacity to accommodate infill development, including modest increases in residential density, for approximately 5,000 persons. Major undeveloped areas which can be served by existing sewer lines are: a portion of the Willow Creek Watershed; the area south of U.S. 6, east of Gilbert Street and west of Sycamore Street; and the area in the north branch of the Ralston Creek watershed north of Rochester Avenue and west of Scott Boulevard. Once the new river corridor sewer improvement is completed, the area south of Interstate 80 between Dubuque and Dodge Streets will be served as well as the 100 ,aicam loan sv DORM MICROLAB :-!A B JORM MICRULAB CLUAk k47 L)' AhU „L� a. . peninsula area which is bounded by Dubuque Street on the east, by the Iowa River on the south and west, and Interstate 80 on the north. The provision of sewer service to the above-mentioned areas is limited by the capacity of downstream trunk sewers and the capacity of the city's sewage treatment plant. B. COST EFFECTIVE SEWER SERVICE The development of areas contiguous to existing or proposed major sewers with adequate system capacity is generally the most economical form of development. It is therefore recommended that areas of existing sewer capacities and areas which are to be provided with adequate sewer capacity in 1978-1979 be initially developed. This will include the following areas: a. Infill development b. Eastern portion of the Willow Creek watershed area C. Area south of U.S. 6 between South Gilbert and Sycamore Streets d. Peninsula area west of Dubuque Street e. Area between North Dubuque Street and North Dodge Street south of I-80. Upon completion of the proposed new wastewater treatment plant facility on South Gilbert Street, areas which could be 101 amaa n.ni , B) JORM MICROLAS x,1,1' : ;L'III .

Undeveloped area in eastern Iowa City known as Village Green Rehabilitation and increasing the capacity of existing sewers within the community and in the area draining into the north branch of Ralston Creek will allow for the following developments: a. Infill development in the established portions of Iowa City, and b. The north branch of Ralston Creek west of Scott Boulevard Once a final pattern of priorities has been established, new development should occur contiguous to existing developed areas. The areas which are located east of Scott Boulevard and in the western part of the Willow Creek watershed, generally west of Mormon Trek Boulevard will not be able to be provided with adequate sanitary sewer service until substantial sewage system improvements are made. Also, the area in extreme northwestern Iowa City which is within the Clear Creek watershed can not be economically provided with sanitary sewer service. 102 Ri,I I II4( p BY DORM MICROLAS J by JURM MICROLAb �tUAK RAPIJS AHO AL C.

Construction of Melrose Avenue around University Heights, or widening of Melrose Avenue along the southern border of the University of Iowa Medical and Sports Complex, construction of a diagonal from Melrose Avenue to the Burlington Street Bridge. Continued discussion with the University of Iowa may result in alternative solutions (such as a West Campus bypass) to traffic routing in the area of the Health and Sports Complex. The projects which will have the most significant impact upon regulating growth are those that will provide access to areas currently without paved roads. The combined effect of providing access coupled with extended sewer service will be a strong impetus for development. D. PHASING PUBLIC IMPROVEMENTS The ability of the City to provide municipal services and 104 JoRM MICROLAS ;L %o HY JORM MIGROLAB (tDAR RAPIu� ANU JL'�. ^^ facilities, particularly sanitary sewer service and major traffic - ways, has a direct impact on the sequence in which areas of the community develop. The availability of public facilities does not greatly affect the community's overall growth rate. However, because financial limitations make it necessary to schedule the construction of new public improvements over a number of years, the time at which specific areas can be provided services varies. In the analysis of alternative waste water treatment plant sites, emphasis was placed upon incremental expansion of capacity within and around the perimeter of the existing developed area, rather than redirecting growth to a particular sector. Contiguous growth which utilizes capacity of existing facilities is more economical than building all new facilities for new development. However, the location for the new waste water treatment plant does make it more economical to develop the area close by, than to extend new trunk sewers to other undeveloped areas around the perimeter of the city. Major trafficways provide a development framework. An orderly functional classification system in both existing and new areas ensures the availability of rights-of-way in appropriate locations to serve the anticipated volumes of traffic generated within each area of the city. Because the transportation network not only provides access to adjacent property, but also serves to carry traffic from location to location, system continuity is important. It is frequently necessary to extend major trafficways to logical connections with the existing system, even though the development of adjacent property is not imminent. The schedule below contains the recommended sequence for the provision of public improvements. The schedule contains four 105 ...

INTRODUCTION I.LUAH kAHJ'j ANu Oc. . . 4,: The implementation of this Comprehensive Plan will involve the use of a complex mix of implementation tools. A municipal government, in carrying out policies set forth in a Comprehensive Plan, does so primarily by enacting regulations or by allocating resources. Zoning ordinances and subdivision regulations are the primary land use regulatory devices. The Capital Improvements Program and capital budget are principal tools used to manage the expendi- ture of funds for purposes established in the Comprehensive Plan. Annexation as a policy tool, has direct impact on the spatial pattern of development planned for in the Comprehensive Plan. Cooperative agreements with other public bodies provide additional management capability in carrying out community development policies. D. ZONING A revised ordinance will be one of the major means of imple- menting the Comprehensive Plan. In this manner, the City, pur- suant to Iowa Code Chapter 414, will adopt the regulations and restrictions which will, in large measure, implement the ranges of population density and locations for various types of land uses which are shown on the Comprehensive Plan Map. 109 :.nr Rui ilia.) fn JORM MICROLAB :..purr �L'•1; by JORM 1.11LROLAB LrUArt RAPI iL Aflb jc1 %w.'+t . The specific source of the City's power to so regulate is found primarily in Iowa Code Sections 414.1 and 414.2. Under Section 414.1, the City, for the purpose of promoting the health, safety, morals or the general welfare of the community, is em- powered to regulate and restrict the height, number of stories, and size of buildings and other structures. Also the City may regulate the percentage of lot that may be occupied, the size of yards, courts, and other open spaces, the density of popula- tion and the location and use of buildings, structures, and land for trade, industry, residence, or other purposes. Section 414.2 goes on to provide that for any or all of said purposes the City Council may divide the City into districts of such num- ber, shape, and area as may be deemed best suited to carry out the purpose of Chapter 414. Within such districts the City may also regulate and restrict the erection, construction, recon- struction, alteration, repair or use of buildings, structures, or land. A limitation is that all such regulations and restric- tions must be uniform for each class or kind of buildings through- out each district, but the regulations in one district may differ from those in other districts. Therefore, Iowa Code Chapter 414 delegates specific power to the City of Iowa City to enact the zoning regulations which will implement portions of this Compre- hensive Plan. Additionally, Iowa Code Section 414.3 requires such zoning regulations to be made in accordance with a Comprehensive Plan. Therefore, the Comprehensive Plan and the revised Zoning Ordin- ance are complementary. The zoning regulations, in large measure, implement the Plan, while the Plan serves as a basis of the zoning 110 -,ur.wil ivato iso JORM MICROLAB :L`I,- M JORH 1.11CROLAb LLDAi kAPIJ5 AND ,,L� regulations. Thus, the Comprehensive Plan embodies policy deter- minations and guiding principles while the revised Zoning Ordin- ance will provide the detailed means of giving effect to those principles. The City has given careful consideration to the community's land use problems and, after careful study of its present and foreseeable future needs, has adopted this Comprehensive Plan. The amended Zoning Ordinance to follow will divide the city into districts and regulate land uses within those districts in ac- cordance with this Comprehensive Plan pursuant to the Iowa Code. The overriding consideration upon which designation of zones in the revised Zoning Ordinance will be based is the compatibility of the zoning district regulations (in terms of character and uses permitted) to the designation indicated by the Comprehensive Plan Land Use Map. Table I indicates the type of compatible zoning designations that are intended for the various Comprehensive Plan Land Use Map designations. An examination of Table I reveals that within several of the Comprehensive Plan Land Use Map designations, more than one zoning district designation may be appropriate. Also, there is overlap so that a zoning district which is compatible within the 8-16 DU/A designation, for example, is also compatible within the 16-24 DU/A designation. In drawing actual zoning 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. 111 JORM MICROLAB ?: by JORM MICk.ULA6 TABLE 1 ZON.IN_G_.

"' The City of Iowa City's review and approval power over sub- division plats gives the City another means of implementings its Comprehensive Plan. Iowa Code Section 409.14 provides that no county recorder shall file or record any plat purporting to lay out or subdivide any tract of land into lots and blocks within any city having a population by the latest federal census of 25,000 or over, or within two miles of the limits of such city, unless such plat has been first filed with and approved by the council of such city as provided in Section 409.7, after review and recommendation by the city planning commission in cities where such commission exists. The fourth paragraph of Section 409.14 contains language which clearly authorizes review of said plats for conformance with the city's Comprehensive Plan where such exists. "Said plats shall be examined by such city council and city plan commission where such exists, with a view to ascer- taining whether the same conform to the statutes relating to plats within the city and within the limits prescribed by this section, and whether streets alleys, boulevards, parks and public places shall conform to the general plat of the City and condone to an orderly development thereof, and not conflict or interfere with rights-of-way or extensions_of streets or alleys already established or otherwiseinterfere with the carrying out of the Comprehensive City Plan, in case such as has been adopted by such city. If such plats 118 - !II(Hbf III-If.I OI' JORM MICROLA13 LL UA,< kNP1 JJ A; I tl JLC i It. • . shall conform to the statutes of the State and ordinances of such city, and if they shall fall within the general plan for such City and the extensions thereof, regard being had for public streets, alleys parks sewer connections, water service and service of other utilities, then it shall be the duty of said council and commission to endorse their ap- proval upon the plat submitted to it; provided that the City Council may require as a condition of approval of such plats that the owner of the land bring all streets to a grade ac- ceptable to the council, and comply with such other reasonable requirements in regard to installation of public utilities or other improvements as the council may deem requisite for the protection of the public interest." (emphasis added) Clearly, it is the duty of the City Council to approve such plats if they conform to the State statutes, the ordinances of the City, and the City's Comprehensive Plan. Just as clearly, the Council need not approve such a plat if it interferes with the carrying out of the Comprehensive Plan. Finally, the City Council may require as a condition of approval compliance with reasonable requirements in regard to installation of public utilities or other improvements Council deems requisite for the protection of the public interest. Therefore, should the City Council deem it requisite for the protection of the public interest that an amount of land for parks based on the standards specified in this Comprehensive Plan be provided for the residents within a subdivision, it could 119 Idi(HOI ILnla 0: DORM MICROLAB I,LJArf RAPiJJ ANN JL i,; IL ..'r,. adopt a mandatory dedication ordinance. Such an ordinance would require a developer, as a condition to plat approval, to dedicate or pay fees -in -lieu of dedication, in order to provide land for parks to serve the future residents of the developed subdivision. Such subdivision development without provision for neighborhood parks as shown on the Comprehensive Plan Land Use Map and as re- quired through a mandatory dedication ordinance based on the Com- prehensive Plan, would interfere with the carrying out of the Comprehensive Plan, and would therefore be disapproved by the City Council and Planning and Zoning Commission. By this process of review, City Council and the Planning and Zoning Commission can guarantee that subdivision plats would not interfere with the carrying out of Iowa City's Comprehensive Plan, regard being had for public streets, alleys, parks, sewer con- nections, water service and service of other utilities. In this manner, Iowa Code Chapter 409 has granted review authority to the Iowa City Council and Planning and Zoning Commission, and created a mechanism by which the land subdivision process can be managed in accordance with the City's Comprehensive Plan. City Attorney John Hayek's memorandum of March 5, 1974, to the Mayor and City Council regarding mandatory dedication concluded: "The status of mandatory dedications in Iowa is uncertain as the memorandum indicates (reference is to a research memorandum of February 8, 1974, by Assistant City Attorney Dick Braun). Chapter 409 of the Code of Iowa does not spe- cifically grant municipal corporations this power. However, it is our opinion that the City does have the power to 120 a(a+nnuai:) !0 DORM MICROLAB ;LI';, BY JURM MICROLAb UUAIk kal'i.n "') IJL, r.'I"t . require mandatory dedication or fees -in -lieu of dedication if the following standards are adhered to as set forth in the memorandum: 1. The park required must be included in our comprehensive or general plan. 2. The subdivision exaction must be considered reasonable, with regard to the subdivision in question. 3. The requirements must be attributable to the specific needs of the subdivision in question. 4. The advantage gained from the requirement must be used to the direct benefit of the people in that subdivision. You should be aware that enactment of mandatory park land dedications would probably result in litigation in the courts over the issue because of the cost of compliance with such requirements to subdividers along with the un- certainty of the legal status of the requirement." 121 JORM MICROLAB -';,:,, I) I, L'1,,,BY JURM MICRULAB u (LDAK RAPIJ) AND JLC PROGRAMMING CAPITAL EXPENDITURES The Comprehensive Plan establishes a pattern of orderly growth for the community. Central to this orderly growth is the frame- work of public facilities around which the community develops. The Capital Improvements Program and the capital budget are the principal management tools available to ensure that the needed public facilities can be provided at the time and in the locations necessary to ensure efficient and orderly development. The Cap- ital Improvements Program links the development policies estab- lished in the Comprehensive Plan to the future expenditure of funds and provision of capital improvements. In general, the timing and the location of the provision of major public facilities such as trafficways, the sanitary sewer system and the water system have a more profound effect on a community's development pattern than regulatory measures. The Comprehensive Plan includes the needs for public facilities which were identified during the planning process. The Plan also establishes policies regarding the provision of public facil- ities, even where the specific facilities have not yet been identified. Need for additional capital expenditures will become apparent, from time to time, as community growth occurs. The Capital Improvements Program serves two primary municipal management functions. First, the City systematically reviews all capital facilities 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. Second, 122 YICNb� LFII J n� JoRM MICROLAB BY JOkM MILkOLAi LtUA;< kAI'IJ" ANO JLC i, . IL . . 'I. - the Capital Improvements Program serves as a strong financial management tool. State law and sound fiscal policy impose limita- tions on the ability of the City to undertake major capital pro- jects. By systematically evaluating capital projects, priori- tizing 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 Capital Improvements Program (CIP) is a mid-range (5-10 year) planning and management tool. It should include all capital facilities requirements expected to be needed within the established time period. Capital improvements programs are generally pre- pared jointly by the planning staff and the finance staff, with assistance from the departments with capital facilities needs. The CIP process normally prioritizes all foreseeable capital needs. This priority ranking is followed by an assessment of financial capability, debt limitations, debt service ability, and the identification of sources of funding. Based on this information, capital expenditures are programmed to occur over the designated five to ten year period. The high- est priority items are included in the program for the first year, consistent with financial limitations imposed by State law or the fiscal policy. The first year of the Capital Improvements Pro- gram becomes, after the City Council deliberation, the capital budget for the next fiscal year. Because capital improvements needs cannot always be foreseen, and because priorities change, the capital improvements programming process should be undertaken annually. Adjustments to the schedule must be made according to changed priorities or circumstances. The use of a Capital 123 ioRM MICR©LOB :n ;L'I:L. BY JURM MICROLAb E. CEUAr RAPID; AND uL, . . )1— Improvements Program does provide the essential link between the goals and objectives set forth in the Comprehensive Plan and the financial management of the provision of needed public facilities. OPERATING BUDGETS 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. F. ANNEXATION At the present time, no official City policy regarding an- nexation exists. However, the Utilities, Landforms, Land Use Concepts and Locational Factors Reports found in Appendix A all suggest an approach to annexation based on protecting watersheds. This approach must be taken into consideration along with the 124 MI(gill ILI'II ,) B) DORM MICROLAB :,... Br JUHM MICHULAI CE'uA I:Al iu; AW o other factors discussed in this section in making any annexation decision. The following factors should be considered by the City Council prior to making a specific decision on whether to annex a particular area: 1 2 3 Whether the given annexation will bring within the city limits, a portion of a watershed over which the City should exert control. The Landforms Guide in Appendix A identifies water- sheds which can be used as planning units. This publication concludes that flooding and sewer service problems can be minimized by a process which utilizes the characteristics of watersheds as planning guidelines. Whether increased land use controls (above and beyond the extraterritorial subdivision control of the City) are neces- sary to control development in an area. If so, annexation would be indicated. In some instances, the City may wish to exert zoning control along existing and potential high- way corridors or interchanges to guard against inappropriate development and to protect traffic carrying capacity. Bring- ing areas within the City's zoning jurisdiction by annexa- tion gives the City control over land use location and intensity. Thus, annexation would be indicated in areas where control over development is desired, such as sensitive environmental areas identified in the Vegetation Guide and Landforms Guide in Appendix A, and the River Corridor Study. Whether the annexation is fiscally sound for the City of Iowa City. The financial implications of annexation are complex. 125 JoRM MICROLAEI . "A; :'-'!: L isY .iURM MICROLAb 4 LLJArt kA'r11U'3 Allo JL, "..:�L , . "•,. The City is required to expend additional money to serve the annexed areas. Annexation will spread the payment for facilities and services over a broader area, and thus will tend to reduce the amount levied per $1,000 of assessed value of taxable property. There is the complicating factor in that the Iowa Code Section 24.36 limits the aggregate increase of the General Fund levy, as well as several other specific levies, to 7%, or in certain circumstances, to 9%. Yet, limited facilities and services will be serving a broader area. Therefore, annexation will not serve to im- prove the fiscal posture of the City. The City assessment may be spread somewhat; however, the increase in the General Fund levy is still limited by law. If the percentage limit is removed, the ultimate fiscal question is whether the increased tax base derived from annexation is. sufficient in view of the cost of extending substantial municipal services not previously provided in the annexed area. It is beyond the scope of this Compre- hensive Plan to answer this question for annexations in general. Rather, this consideration must be made on a case by case basis in analyzing proposed annexations. Whether the City has the capability of extending substantial municipal services and benefits not formerly enjoyed by the residents of the proposed annexation area. Proof of this capability will negate any claim that the City annexed the area solely to increase its tax revenue. The City has the 126 in uni ;IM!., s0 JORM MICROLA6 u:,L-.L„ BY JORM HICROLAb (,L UAk RAF'1 J�� AIIJ JL'.; :,L- , , 'o: burden of proof and whether there will be a substantial increase in services becomes a question of fact for the courts which will consider the level of services before and after annexation. However, it is not necessary that all services be extended before the City is entitled to annex adjoining property. G. COOPERATIVE AGREEMENTS To effectively implement this Comprehensive Plan, the City of Iowa City needs to work closely with other government entities. Cooperation and coordination between these various governmental units will be necessary to ensure implementation of Iowa City's Comprehensive Plan in regard to transportation, community facil- ities, and development outside the city limits. Agreements need to be explored in the following areas: 1. An agreement to constitute a basis for actions of the Iowa City School Board and the City of Iowa City in executing a plan for cooperation, joint planning, and respective use of school buildings, neighborhood playgrounds, playfields, parks and school/park sites in the. City of Iowa City. In such an agreement, the school board and the City would mutually agree that, in acquisition and planning of a school, recreation or park area, whether acquired jointly or inde- pendently, each will inform the other as far in advance as is practicable, of its plan for acquisition and development of sites which may become mutual resources. It would be 127 DORM MICROLAS ":�,tOi .L''It J by JURM MICRULAB LLUAR kAPIOS AND OLI !v, '"L • - W, understood that neither governmental unit would be obligated to conform to the desires of the other. However, it is recognized that such cooperation in acquisition, planning, and construction will create certain economic advantages. 2. An agreement between the City of Iowa City and Johnson County relative to development standards and land use in the area outside the city limits but within the City's extraterri- torial jurisdiction. 3. An agreement between the City and the University of Iowa regarding permitted land uses along the interface of property under City and University jurisdiction, as well as the use of utility services and trafficways through City and University property. In this manner, it is hoped that an ongoing effort by the various governmental entities will serve to increase the services provided by all, heighten efficiency of operations of each, and fulfill specific obligations to the citizens of the community with the lowest cost to the taxpayer. 128 ILII.

CONCLUSION This Comprehensive Plan is the culmination of a lengthy process which has required considerable time and effort. The Comprehensive Plan will be most useful in future years if it is utilized as a valid working document and as a guide for decision-making. The Plan has been prepared based on the gathering and analysis of factual informa- tion, commentary from thousands of citizens, and on endless hours of work contributed by local governmental officials and City staff per- sonnel. In order to protect this substantial investment of time and effort, it is essential that future Planning and Zoning Commissions, and City Councils periodically update the Plan in order to adequately reflect changes occurring in the community. Although the Plan generally ad- dresses itself within a twenty (20) year time frame, a thorough review of the Plan should occur every three to five years. It is also recom- mended that when Council policies deviate from the provisions of the adopted Plan, that the Plan be amended in order to accurately reflect current Council policies and priorities. 129 DORM MICROLAS n.

The Planning and Zoning Commission has reviewed and transmitted Appendix B to the City Council for consideration as part of the Comprehensive Plan Text. NEIGHBORHOOD COMMERCIAL CENTERS The location and size of the proposed neighborhood commercial centers shown on the Comprehensive Plan Land Use Map reflect the economic goals and objectives expressed in the Plan. It was an economic objective to provide for neighborhood commercial centers designed to blend in with, and serve, residential neighborhoods. Thus it was recommended that use of Planned Unit Development be encouraged to maximize the ability to effectively blend neighborhood commercial activity into residential neighborhoods. However, it was also recommended that there be no zoning or rezoning for additional large commercial areas that would detract from existing commercial areas. The neighborhood commercial centers shown on the Plan Map reflect a balanced approach of providing for neighborhood commercial centers in a trade area large enough to support them, while recommending that their size be such that they will not detract from existing com- mercial areas. Assumptions 1. The major function of a neighborhood commercial center is the sale of convenience goods and personal services. 2. Neighborhood commercial centers were located where possible 133 _. flCRul HUM1 ) Ilv jORM MICROLA6 ',:.,tw;:L>1,U BY JORM MICROLAB ULOAR RA{'IUS ANO Aj . ,"+1` near the intersection of secondary arterials or collector streets. 3. The minimum population to support a neighborhood commercial center was deemed to be 4,000. However, service areas delineated ranged from approximately 7,500 to 14,000 in potential population to ensure adequate support. 4. Total site area for neighborhood commercial centers should be no larger than 7 acres. 5. in order to achieve the desired scale for neighborhood com- mercial centers, a standard of one (1) acre per 2,000 population was utilized to arrive at a recommended site area for centers shown on the Plan Map. This standard reflects the policy decisions that the type of neighborhood commercial centers desired would be no greater than 7 acres in size and have a limited number of stores designed to serve residents of the area. 6. Four (4) new neighborhood centers were located on the Land Use Plan Map based upon nearness to secondary arterial or collector street intersections, central location to an ade- quate service area population, and proximity to higher density residential land uses. 7. Trade areas were delineated for the four new neighborhood commercial centers by assigning population to the nearest neighborhood commercial center (new or existing). This delineation of the trade areas was simplified by using straight line distance in calculating the nearest center (See Appendix B Map H2). The four new neighborhood commercial centers shown on the Com- prehensive Plan Land Use Map are as follows: 134 _,na+oi uMrn nv JORM MICRmLAB . :LYi,o BY JORM Id1CkOLAB uLDAII kAPM Arlb Uu • I 'V. A.

According to the recommended standards in this report, for the approximately 95,000 potential population depicted on the Land Use Plan Map, two 100 acre (minimum) city-wide parks should be provided. Hickory Hill Park (approximately 17.5 acres) and the adjoining 80 acres of undeveloped City cemetery property serves as one community/citywide park. The 80 acres will be gradually reduced as more cemetery space is needed. However, much of this land will be in park use for the next 20 years. A 20 acre addition to Hickory Hill Park has been proposed. City Park (105.2 acres) is the second community/city-wide park which serves Iowa City. The Community Facilities Report recommends provision of ten acres of community and city-wide park land per 1,000 population. Currently there exists ten acres of park land per 1,000 population for all types of park land, approximately eight acres per 1,000 population is provided for city/community-wide park land. However, park and recreation area provided by the University of Iowa is not included in the city park totals, but certainly contributes valuable recreation opportunity. Private recreation areas, such as golf courses, fair- grounds, and similar areas, were also not included. In addition, Coralville Reservoir, Lake Macbride State Park, and Kent Park provide similarly valuable recreation opportunities. For these reasons, it is recommended that seven acres (as opposed to ten acres) per 1,000 population of community and city-wide park be allocated as the city develops.

This acreage will be provided primarily in the form of a new riverfront park (approximately 200 acres) shown on both sides of the Iowa River southeast of the Airport. (Mesquakie Park adjoins this proposed riverfront park and is 64 acres in size.) Another park, approximately 40 acres in size, is shown along the Iowa River opposite the old Coralville Power Dam (11 acres of neighborhood park land is allocated towards this 40 acres). These two riverfront parks are in accordance with the recommendations of the Iowa River Corridor Study completed by Stanley Consultants in 1977. The proposed 20 acre addition to Hickory Hill Park will also contrib- ute to the necessary additional community/city-wide park land. Five acres per 1,000 population of neighborhood and mini -park land was recommended in the Community Facilities Re ort and subseq- uently adopted by the CPCC. Currently, there are approximately two acres per 1,000 population of neighborhood and mini -parks. However, school playgrounds were not included in this total and these areas frequently serve as neighborhood parks. The following assumptions were made in the distribution of neighborhood park land: 1 2. Neighborhood parks 'are allocated at five acres of neighbor- hood park per 1,000 population. Neighborhood parks should be a minimum of five acres in size. 3. Residents in areas where the density is greater than two dwelling units per acre should be within 0.6 miles of a park where possible. 138 DORM MICROLAB , _;OJn .L''!: , BY JORM MICkOLAb LLOArt RAViu; A,1C ul_' ;,...'.L.. . ".. 4. In areas shown on the Land Use Plan Map as developing at two dwelling units per acre or less, no neighborhood parks will be allocated as adequate open space exists for residents of these areas. 5. Generally, the existing population of Iowa City is adequately served by existing city parks and other usable open space. 6. Where redevelopment at a higher residential density than currently exists in an area is indicated by the Land Use Plan Map, the higher population density was considered in allocating new neighborhood parks. 7. In fringe areas or new neighborhoods not totally developed, potential total population (existing and future) was con- sidered in neighborhood park allocation. 8. Parks are located (where possible) in areas where attractive physical features exist such as rivers, streams or lakes, scenic views, woodlands, or rock formations. 9. A minimum of ten acres of park land (neighborhood or community/city-wide) should be located adjacent to each potential school site. 10. Greenways along rivers and streams were not included in allocated park land, unless they were within existing or proposed parks. 11. Neighborhoods are defined as units of potential population of approximately 5,000-7,000 persons, divided along barriers such as major trafficways, rivers, major change in land use, and similar features. 139 T� Y'111011'1 6, JORM MICROLAS L 'I;�,rirlr iL''1z- IiY JUM MICROLAli • UDAR kAPI0� ANU ULI iiIiu'It 'r ."

Dubuque Street, south of Rapid Creek, and west of the Office Research Park on Highway 1. Land Use Existing land use includes very low density residential, woodlands, and agriculture. Proposed use is very low density residential (less than 1 dwelling unit per acre) because of the broken topography, woodlands, and lack of sanitary sewer service. Population Approximately 35 residential dwellings are in this neighborhood, most are located along Linder Road. Additional land is available for approximately 325 new units, with a corresponding population of about 915 additional persons. Utilities This area cannot be economically served by sanitary sewers. Therefore, residents will require septic tanks and individual lots will be sized according to soil sample results. 150 :11 C11101 I Of DOR M MIC ROLA S ;,,I[ BY JORM MICROLAU NEIGHBORHOOD II • LEAR kAPIJs AND uL This area in the northwest of Iowa City is bounded by the Iowa River to the west and south, and by North Dubuque Street on the east, and I-80 to the north. Land Use Existing land use in this area of approximately 530 acres is mainly open space and agricultural. A mobile home court and some apartment units are located near I-80 and North Dubuque Street. A number of single-family dwellings are located along the river on Taft Speedway, Foster Road and Knollwood Drive. The Elks Club, with recreational facilities and a golf course, covers approximately 70 acres in the center of the peninsula. Much of the land adjacent to the river is in the flood plain. Proposed land use for the peninsula is largely low density residential (2-8 dwelling units per acre) with some higher density residential (8-16 dwelling units per acre and 16-24 dwelling units per acre) in the area between Foster Road and I-80. Population There are currently approximately 210 dwelling units in the peninsula area. The Plan projects an additional 1,740 dwelling units for an increased population of about 5,000 residents. 152 —.�aicuw n�au� oti JORM MICROLA9 �,,,,o; :L''.,v BY JORM MICROLAB Utilities LEOAk kAVIJS ANu JL, Flu, IL, . A new north -south trunk sewer on the east side of the Iowa River, extending to Foster Road, will be installed in 1978. Upon completion of this sewer the entire peninsula can be serviced. Water is already available to this area as are other utilities. Transportation Foster Road will be the main collector street serving the pensinsula and linking with North Dubuque Street. Community Facilities A five acre neighborhood park is proposed in the northern part of the peninsula to serve the higher density residential area. A 20 acre park/school site will be reserved in a location central to the peninsula residents. A 40 acre riverfront park located near the Coralville Power Dam will serve not only the residents of the penin- sula (11 acres is intended for this use) but also as a community park for all Iowa City residents and canoeists, bicyclists, hikers and fishermen using the river and river side trail. A river corridor buffer at least 100 feet wide, with a bikeway/walkway trail is planned along the river as part of a continuous trail system. Terrill Mill Park, a community park, about 18 acres in size, is located between North Dubuque Street and the Iowa River in the southeast corner of the peninsula.

This trafficways plan represents a street system designed to serve the needs of Iowa City by the year 2000. This plan is not expected to be fully implemented by 2000, but it includes some projects which will likely be built, and corridors that should be protected. The functional classification of the streets is intended to ensure this protection by reser- vation of sufficient right-of-way for eventual street construction. The plan is based on the assumption that new urban intensity development will take place largely within the existing city limits plus the Ralston Creek and Willow Creek watersheds and the area immediately south of the city limits and east of the proposed sewage treatment plant. A map of the traf- ficways plan is contained on the fold -out page following the design standards. FUNCTIONAL CLASSIFICATION. Functionally, trafficways need to fulfill two roles: circulation and access to property. The trafficways plan es- tablishes a functional classification of primary arterial, secondary arter- ial, collector and local streets, with each classification representing a shift in relative importance of the circulation and access functions. A. PRIMARY ARTERIAL streets' principal function is to provide for vehicular circulation. Primary arterial streets should be designed to carry large volumes of traffic (15,000 or more vehicles/day) and should form a continuous system of a ring and radial streets serving the core of the city. Primary arterial streets serve as the principal truck routing system of the community and, because of the adverse effects of trucks and large volumes of traffic, they should be well buffered with land- scaping and ample rights-of-way. Access to primary arterials should be strictly limited, and driveways should not be permitted to have direct access to primary arterials. 184 alcum,uato Hr JORM MICROLAB : .L5!:, iiY JURM MIC ROLAu LLUAtt RAVIJS AND ULi� . . B. SECONDARY ARTERIAL streets serve a dual function of circulation and access, with circulation taking precedence. Secondary arterial streets should be developed to carry large volumes of traffic (5,000-15,000 vehicles/day) in a grid and radial pattern which supplements the primary arterial system. Secondary arterial streets should offer direct prop- erty access only to large industrial, commercial, institutional, and multi -family residential sites and should be buffered from residential uses by ample landscaped transitions. Driveways should not be permit- ted to have direct access to secondary arterials. C. COLLECTOR streets serve the dual function of circulation and access, with access taking precedence. Collector streets should be designed to carry moderate volumes of traffic (1,000-5,000 vehicles/day) rela- tively short distances to and from arterial streets. The collector street system should be discontinuous, with street lengths no longer than one kilometer (0.6 mile) as a general rule. Collector streets should provide access to all types of land use, however access for single-family residences should be onto local streets. D. LOCAL streets serve the function of access to property. Local streets should be designed to carry only small volumes of traffic (up to 1,000 vehicles/day) and to discourage both high-speed and high-volume use. The local street network should be relatively continuous, but individual streets should neither extend much beyond one kilometer (0.6 mile) in length nor have direct access to primary arterial streets; access to secondary arterial streets should be minimized. Local streets should provide access to all land uses except the most intense uses such as industrial, institutional and commercial. 185 _tn �,�d n.Mtri us DORM MICROLA13 �';,.�•:��� ;L'•i � 6Y JORM 111CROLAB LLAk RAPIJS AND JL., lo, ,"' TRAFFICWAY DESIGN STANDARDS. The following design standards are recommended for the Iowa City trafficway system. The primary need for these design stand- ards is to ensure that the proper right-of-way width is obtained. The desig- nation of primary and secondary arterials and collector streets in advance of development in order to limit access along these routes is an important consideration. Trafficway design standards should be required within the two mile extraterritorial jurisdiction as appropriate. The pavement de- sign should be in accordance with public works design standards (Proposed Design Standards for Public Works Improvements in Iowa CCS, Iowa, April 1975) as amended from time to time. Severe physical restraints, identified need for neighborhood protection, and similar factors may require modifica- tions of these standards when applied to specific areas. Existing arterial and collector streets which are below standard will not be widened unless noted otherwise on the Land Use Plan Map. The typical cross-sections, below, do not include turning lanes, the right-of-way width would remain the same if turning lanes were added. (Note: These standards have been modified from the standards published in the Iowa gat Plan: Trafficways Report included in Appendix A.) 1. Primary arterial streets are to be developed as boulevards or express- ways, with a median separating opposing flows of traffic. At inter- sections medians will be used to provide left turn storage lanes. No parking is permitted on primary arterials and maximum acceptable grade is 8%. Access will be controlled and driveways will not be permitted to have direct access to primary arterials. The median should be designed to protect vegetation from fall spray and snow removal operations. DORM MICROLAS 2 fiY JORM MICROLAB Uiufw RAPIJ� AMU Ju Ibl�+L... ..u..l Secondary arterial streets should be designed as four -lane facilities except in commercial areas where they may be designed as three -lane facilities. At intersections with other arterial streets it may be desirable to add a lane for left turn movements which preclude some landscaping for one-half block in each direction from the intersection. Access will be controlled and driveways will not be permitted to have direct access to secondary arterials. No parking is permitted and maximum acceptable grade is 8%. A twenty-five foot pavement (two - lanes) centered in the right-of-way should suffice as an interim con- struction project, in newly developing areas. 187 :11(Ro1 10.11..)

This paving width would provide parking on both sides and two narrow traffic lanes when traffic volumes are relatively low. In the future, as traffic volumes warrant a change, parking on one side would be re- moved to provide a good two-lane facility for a collector street. If the Council does not desire to provide on -street parking along col- lector streets, a 28 -foot facility (two -lanes) would be adequate. At intersections with arterial streets, a left -turn lane should be pro- vided by eliminating parking for one-half block on 36 foot wide streets, or by widening to three lanes on two-lane facilities. Collector streets should not be longer than 0.6 miles to discourage through traffic and maximum grade should not exceed 10%. Driveway access for single-family residences should be provided on local streets. 0 1 ,10)1 1LX, , 8V JORM MICROLAB (,GUAR kAPIJ5 ANU A .- 4. The primary local street is intended to serve residential areas which have a density greater than 1 DU/A. This type of street should not be longer than 0.6 miles and should not provide a direct route between streets of a higher classification. Parking may be permitted on both sides of the street and maximum acceptible grade is 12%. For areas at a density of 8 DU/A or greater, a 36 foot pavement with a 66 foot right-of-way should be provided if parking on both sides is desired. el 2 . 1 i if �. 4. 5. The rural local street may be developed in areas with single-family residential densities less than or equal to 1 DU/A. This type of street is ideally suited to areas of steep topography, therefore, maximum grades of 20% are acceptible, provided transitions do not exceed 12%. The length of this type of -local street should not exceed 0.6 mile. On -street parking would not be allowed. A sidewalk on one side only may adequately serve the neighborhood's pedestrian needs. 189 JORM MICROLAB LIal; ;L>1Lu BY JORM MICROLAB CLDAR RAPIJS AND Du The following table serves as a summary of the functional classification map.

An asterisk indicates where specific standards are detailed in Appendix B or the Zoning Ordinance. Agriculture: A land use restricted to typical farming operations such as cropland, pasture, feedlots, and farm dwellings. Residential development at a density of less than one dwelling unit per acre may be permitted on land not suitable for agriculture. Alternative Mode of Transportation: Any means of transportation other than automobiles. Generally refers to mass transit, bicycling and walking. *Buffer: Trees, shrubs, landscaping and appropriate fences which serve to screen objectionable views, control environmental factors and protect less intense land uses from glare, noise, dust, and excessive heat. Capital Improvement Program: A five year plan (which is updated every year) for providing capital improvements such as sewers, roads, and parks, which are closely coordinated with the Comprehensive Plan to permit orderly development and redevelopment. Central Business District (CBD): The high density, compact, pedestrian - oriented shopping, office and entertainment area in central Iowa City. Cluster Development: An example of a planned unit development in which dwelling units are built closer together than in a traditional subdivision. While the overall housing density is maintained, the costs of streets and utilities is reduced and, through clustering, common open space is provided. 195 _snisaniniala u� JoRM MICROLAS ! W; :Lih a by JORM MICROLAb ut)AR kAl ioS Ar:u ,,L' 11� -t_ . *Collector Street: Serves the dual function of circulation and access, with access taking precedence. Collector streets are designed to carry moderate volumes of traffic (1,000 to 5,000 vehicles/day) relatively short distances to and from arterial streets. *Community Park Sites: Parks sites intended for use by residents of a large area of the city. Core Areas: Those locations where employment and/or shopping opportunities are concentrated. Comprehensive Plan: A document describing Iowa City's goals, objectives and policies, and their implementation, for use as a guide in public and private decision-making. *Eight to Sixteen Dwelling Units Per Acre (8-16 DU/A): Housing density which includes small lot detached single family homes, duplexes, four-plexes, gardenhomes, townhouses, and mobile home subdivisions. Traditional detached single family dwellings could also be found in this land use area. Extractive: A land use category generally indicating sand and gravel extraction operations and similar uses, and the City landfill. *Flood Plain: Any land area susceptible to being inundated. The hundred year flood plain is delineated on the Flood Hazard Boundary Map (available at the City of Iowa City Engineering Department). *Flood Way: The channel of a river or other water course and the adjacent land areas that must be reserved in order to discharge the one hundred year HZ CRill II.

Fragile Environmental Features: Areas of scarce vegetation types and habitats, unusual topography, scenic views, or important natural resources. *General Commercial: Uses including retail stores, eating and drinking establishments, services (e.g., barbershops) and offices. In some areas, use may be restricted to specific categories such as neighborhood commercial. *Greenbelts or Greenways: Corridors of open space which include bikeways and walkways, providing access to public facilities. Headwaters: The area where the waters forming a creek or river originate. *Highway Commercial: Businesses primarily serving transients such as motels, service stations, restaurants. *Land Consumptive Commercial: A zone for wholesale and retail businesses which require a large amount of land. Included are auto dealerships, whole- sale operations, construction yards, building supply establishments and junk yards. Lateral Sewers: Sewers serving individual building connections and dis- charging wastes into trunk sewers. Lift Stations: Pumping stations which pump waste water to a higher elevation so that it can then be carried in a sewer by gravity flow. 197 JoRM MICROLAB •t; ,.';-J; ,L:4, o BV JURM MICRULAB LLUAk RAVIJS ANU ou °!,j,"L . *Local Street: Serves the function of circulation for access to property. Local streets are designed to carry only small volumes of traffic (up to 1000 vehicles/day) and to discourage high-speed and high-volume use. *Manufacturing: Land uses including heavy and industrial uses such as grain elevators, food processing, and assembly plants. Multi -Core Development: Development which is planned around a number of areas or cores where employment and/or shopping opportunities are concentrated. *Neighborhood Commercial Centers: Small centers usually including a grocery store, drug store and possibly a few other stores which primarily serve the surrounding residential area. *Neighborhood Park Sites: Potential park sites intended primarily for use by the surrounding neighborhood. *Office Zone: Professional offices and related retail firms such as pharmacies are located in this zone. *Office Research Park: A land use including service oriented industries which serve an area larger than Iowa City, such as data processing. Offices may also appear in this land use. *One Dwelling Unit Per Acre (1 DU/A): Areas which cannot be efficiently served by sanitary sewers or have relatively steep or broken topography yet are suitable for residential use, are designated for a density of one dwelling unit per acre and less. Septic tanks can be used in these areas. IM JORM MICROLA9 "I. 1,1<O; :L`1i I fiY JORM MICkOLAb L,EOA'i, kAVIUS ANU OL, ';':I'LL. , . 'r.. Out Fall Sewers (Interceptor Sewers): Convey waste from trunk sewers to the waste water treatment plant. *Park/School Sites: Suitable locations for potential public schools. The sites will be sized such that when (and if) the schools are built, adequate park land will remain. *Planned Unit Developments (PUD's): Developments with a minimum size of ten acres, or as designated in the zoning ordinance, where a variety of housing types and site design are permitted and integrated with recreation and commercial facilities designed to serve the development. Areas with steep slopes, woodlands or other fragile environmental features are well suited to PUD's. *Primary Arterial Street: Provides for vehicular circulation, with access to property through secondary arterial and collector streets. Primary arterial streets are designed to carry large volumes of traffic (15,000 or more vehicles/day) and form a continuous system of an outer ring and radial streets serving the core of the city. Prime Agricultural Land: That soil which is first in importance and is of the highest quality for production of food and fiber (USDA definition). Soils with a corn suitability rating (CSR) of 70 or more are considered prime agricultural land. (in Johnson County some areas with a CSR of less than 70 may also be considered prime agricultural land, since their pro- ductivity is high enough. The fact that in these areas the slope is more than 5% disqualifies them from the U.S.D.A. standards). *Public and Semi -Public Buildings: A land use designation including hospitals, governmental offices and similar facilities. 199 �ausmii�ar:�isv JORM MICROLAS I_ j( j BY JORM MICROLAB i,EUAR RA✓IJ'; ANU1 0�, ,. _ L - *Public and Semi -Public and Private Open Space: A land use designation including parks, cemeteries and open space. The land may be privately or publicly owned as long as it is primarily open in character. Riverfront Park Sites: Parks which have access to the Iowa River and serve canoeists, bicyclists, hikers, fishermen and others using the river for recreation. *Secondary Arterial Street: Serves a dual function of circulation and access with circulation taking precedence. Secondary arterial streets are developed to carry very large volumes of traffic (5,000 to 15,000 vehicles/day) in a grid and radial pattern which supplements the primary arterial system. Secondary arterial streets offer direct property access to only large industrial, commercial, institutional, and multi -family residential sites. Septic Tanks: A waste disposal system located on the dwelling lot and designed for use by a small number of people. Johnson County Health Regu- lations stipulate minimum lot size of 1 acre for septic tank use. *Sixteen to Twenty Four Dwelling Units Per Acre (16-24 DU/A): This density includes townhouses, low-rise apartments (3 stories or less), and mobile home parks. Strip Development: Commercial or industrial development spread along a narrow corridor generally adjacent to an arterial street. Spot Development: Development of isolated sites not contiguous to existing urban use. El DORM MICROLAO ';:L<w :LAiu BY JURM MICROLAB LEUAR RAP IJS ANU LLQ 10,:I._, . "' *Townhouses: Attached single family dwellings located on a single lot with at least one wall in common with an adjoining dwelling unit. Trunk Sewers: Major sewers which collect waste from lateral sewers and discharge it to outfall sewers. *Twenty Five and More Dwelling Units Per Acre (25+ DU/A): This density includes medium and high rise apartments, usually four to eight stores. Additionally, limited commercial uses may be permitted. *Two to Eight Dwelling Units Per Acre (2-8 DU/A): This housing density includes all detached single family dwellings (except mobile homes) and is typical of most existing residential development. University of Iowa: All properties owned by the State and used by the University of Iowa are included in this land use. Watershed: The area drained by a river or creek system. Zoning Map: A map which assigns a specific zoning designation to each area of the city in conformance with the generalized Comprehensive Plan Land Use Map. The zoning map implements part of the Comprehensive Plan. Zoning Ordinance: An ordinance which implements part of the Comprehensive Plan by establishing zoning districts within Iowa City. The ordinance details specific land uses and requirements for each zoning district. 201 11.1111: 0 BY JORM MICROLAB 1 IdICHOFILtd[D 6Y JORM MICR+LAB LOU R PIDS .

The Plan is meant to be a flexible working document which can be adapted to the changing conditions of the community. The previous Comprehensive Plan was prepared in 1962. Since then, Iowa City's population has increased over 40%, and many other changes have also occurred. That Comprehensive Plan no longer reflects conditions in Iowa City, and does not provide an up-to-date policy framework for current decision-making. The courts have increasingly used a city's comprehensive plan in ruling on land development decisions. In its attempt to balance the wishes of individual landowners with the overall public good, the City must show that its decisions have been based on an adopted plan which clearly states goals, objectives and policies for future growth. This new Comprehensive Plan provides background support and evidence for well thought out policies and planning, important for ensuring a logical pattern and intensity of land use within Iowa City. Various federal programs require cities to have a comprehensive plan before grant applications are considered. This new plan provides basic documentation for grant applications, and places Iowa City in an ad- vantageous position for receiving federal funds. As discussed in the text (in the Capital Improvements Program and Budget setion) the der ust bec cconsidered intplanningrfornthenfuture.financial t herefore, the City may not be able to implement some recommended programs because of a lack of financial resources. The Comprehensive Plan helps to set priorities for city improvements and acquisitions such as obtaining easements or rights-of-way for utilities and sewerrand iwater service,cways. The aand, sconsequently, directs extension in a more cost-efficient manner. Sites for community fthe city'sacilities (e.g. ironmental oncern parks toddevelopment,ldbaseds nfthevinformationcprovidedill be identified in this plan. Considerable citizen and local governmental effort have gone into the preprationrehensive planrder to should betain its carefullysreul- viewed and up -dated by future city councils at least every three years.

IU94A THE COMPREHENSIVE PLANNING PROCESS The Comprehensive Plan Coordinating Committee (CPCC) was established in February, 1976 "to make recommendations to the Planning and Zoning Commission related to the Comprehensive Plan on behalf of the residents of Iowa City" (Rules of CPCC adopted May 3, 1976). The committee was composed of four members of the Iowa City Planning and Zoning Commission and three members of the Iowa City City Council. (A fifth member of the Planning and Zoning Commission joined the committee later in the year.) The committee worked with the planning staff, consultants, neighborhood organizations, and other citizens for a period of 2-� years. During this time, various elements of the Comprehensive Plan were prepared. ELEMENTS OF THE PLANNING PROCESS 1 Citizen Participation Widespread citizen participation is essential to a successful planning process, to ensure that the final plan document reflects the desires and needs of citizens. Sasaki Associates, Watertown, Massachusetts, in cooperation with Attic and Cellar, Inc. Washing- ton, D.C. were hired in October, 1976, as consultants to assist in the ion roram and helppforrmulatensurveys. The consultantr of an ongoing citizen sworkedtwithpCPCto C, city staff and citizens for a five month period. Initial citizen meetings were held in November, 1976.

These organizations provided the first input of citi- meetingsconcerns providedfor initialfuture guidelinesIowa toCity. the Cityissues Council, CPCC,these staff and consultants for formulating questions for the special and general surveys. The Consultants prepared a special survey, which was distributed to about 250 Iowa City residents in January, 1977, for the purpose of obtaining information about their concerns, priorities and ideas for the future of Iowa City.

Included with this guide was a questionnaire which all households were asked to complete. During the week after the People's Guide and Surve was distri- buted, five neighborhood meetings were held to discuss some of the issues raised and to encourage return of the questionnaires. Over 2,000 questionnaires were returned. Computer analysis of these questionnaires provided basic demographic information and indicated the residents' views on how the City should plan for future growth, housing, community facilities, transportation and environmental concerns. All sections of the population were rep- resented by age, income and geographical location. Other neighborhood meetings were held on the Preliminary. Proposal: Land Use Plan (mailed to all Iowa City households in February, 1978). Public meetings were also held by the Planning and Zoning Commission and public hearings by the City Council. 2. Reports and Studies Background reports and studies were prepared to provide basic information for use in preparing the plan. These reports are described in Section III of this document and are included in Appendix A. 3. Issues and Alternatives Information from neighborhood meetings, surveys, reports and studies were used to prepare a list of basic issues to be addressed by the Comprehensive Plan. A number of alternatives for resolving each issue were prepared by the staff, together with an analysis of the land use, social, economic, legal and environmental impacts of each alternative. CPCC discussed these major issues and alternatives and made recom- mendations on how they should be addressed in the Comprehensive Plan. Using this direction a Preliminary Proposal: Land Use Plan was prepared and mailed to all Iowa City households in February, 1978. During the week after the preliminary plan was mailed, five neighborhood meetings were held by CPCC to elicit citizen comments on the plan. 4. Preparation of Plan Elements A revised draft of the Land Use Map was prepared using comments from citizens, boards, commissions and other governmental groups and staff. Using the Issues and Alternatives identified by CPCC and the findings from background studies, goals and objectives, recommendations and policies were developed for the City. In addition, a detailed explanation of the Comprehensive Plan Land Use Map was prepared together with definitions of the land uses. Development standards for various land uses are included in Ap- pendix B. The Planning and Zoning Commission held a public meeting MICROFILM BY ...

O ILMLD 4Y JORM MICROLA6 CEDAR RAPIDS AND ULS HWNL�,, ;UNA BACKGROUND STUDIES & REPORTS In order to provide basic information on existing land use, population, economics and other topics in Iowa City, and to document topographical and other natural features, a series of background reports were prepared by the planning staff. These background reports are included in Appen- dix A of this Comprehensive Plan document. These reports, which catalog existing conditions and recommend alternatives for solving some existing problems, are summarized below. Much of the data in the Report on Population: Summar (January, 1977) is from the 1970 and 1974 e eral censuses. The population of Iowa City was 46,850 in 1970, and 47,744 in 1974. The growth rate slowed to 1.9% in the early 1970's after growth increased by 40% during the previous decade. The census counts reflect a disproportionate number of 20-24 year olds in the population, a characteristic which can be di- rectly attributed to the presence of the University of Iowa. In the Report on Population: Summary, projections suggest that the population will increase at a moderate rate of 500 persons per year. The 1976 Land Use Summar (January, 1977) includes a map of land use in Iowa City. Agriculture and low density residential uses were found to occupy over 50% of the city's land area at that time. The report compares land use in different areas of the city, and identifies several land use -related problems including mixed use areas, land use changes and obsolete sites. The Vegetation Guide (January, 1977) describes eight types of ecosystems found in the Iowa City area.

Report on Housing (March, 1977) relates that the rapid increase in the amount of housing stock during the 1960's has not been enough to offset the growing demand for additional housing in the Iowa City area. The projected housing requirement for Iowa City is approximately 310 units per year, assuming popula- tion growth continues as expected. The breakdown between renter and owner -occupied units can be expected to remain at about 54% to 46%. The Re ort on Housin suggests a decrease in the minimum lot size and si a yard requirements which could reduce single- family housing costs. The report recommends several design elements for making multi -family housing more livable.

Negotiations with the Iowa Department of Transportation to shift the location of the freeway further west have taken place; however, a majority of the City Council is opposed to the construction of a four -lane freeway and pre- fers the construction of a two-lane facility (relocated U.S. 218) in this location. The Prel�iminar� Bikewa s Plan (March, 1976) was prepare o provide a continuous, safe and direct bikeways system in Iowa City. The Locational Factors Report (May, 1977) maps and synt esizes information on soils and topography, vegetation, trafficways, utilities, physical barriers, and distances from core areas in Iowa City. These factors were combined to form a composite map, and to provide guidelines for recommended land use intensity. D The Report on Utilities (May, 1977) discusses boththe public and privately owned utilities needed to serve Iowa City residents. The City provides both water and sewer service to residents.The present water treatment plant capacity is more than adequate for meeting peak demands and is capable of meeting future demands to the year 2000. The existing sewage treatment plant discharge at times exceeds the effluent limita- tions set by the Environmental Protection Agency (EPA) and the Iowa Department of Environmental Quality (IDEQ). The proposed facility will remedy this problem and will provide increased capacity. Electricity and natural gas are provided by Iowa -Illinois Gas & Electric Company. The company is presently willing to supply an unlimited amount of electricity and foresees no problem in meeting future demand. Iowa - Illinois also foresees no problem in supplying natural gas to homes, but industries are already looking towards the use of alternative sources of energy.

MICROFILMED BY JORM MICROLAB GOALS CEDAR RAPIDS AND ULS MOINL�,, IWIA The goals, objectives and policies for Iowa City were formulated using information gathered during the planning process. Consideration was given to residents' needs, desires, and concerns, and to the concept of fairly representing the diversity of the community. In addition, studies of the potentials and limitations of the natural and man-made environ- ment, financial capabilities, and legal constraints were taken into consideration. A number of alternative courses of action were also evaluated. This section of the Plan identifies the overall goals for Iowa City as well as a number of functional goals for land use, transportation, economics, community facilities, housing and the environment. These goals represent the guiding principles of the Comprehensive Plan. OVERALL GOAL It is the goal of Iowa City to protect the health, safety, and welfare of its residents; to allow for individual development and enjoyment; to protect and enhance the heritage and character of the city; to efficiently provide an adequate level of municipal services; to protect the use, value, and enjoyment of private and public land; to protect and enhance the environmental quality of the city and its environs, and to wisely use and conserve energy. LAND USE GOALS I.

Nearly all the factors which affect growth are inter -related. However, to provide clarity, the many considerations are divided into logical group- ings as follows: Land Use, Transportation, Economics, Community Facil- ities, Housing, Environment, and Human Needs. Within the following sections, each functional topic is addressed. The key findings identified during the planning process are set forth. Explicit goals and objectives are identified, and a set of recommended policies is included in each functional section. These recommended policies link future decisions and actions to the goals and objectives which the City desires to achieve. LAND USE FINDINGS Analysis of existing land use patterns can provide much of the basis for a new land use plan. However, several factors besides existing land use influence the location of future land uses. These factors include soils, topography, distance from established core areas, physical barriers, and the location of trafficways and utilities. A detailed discussion of these topics can be found in the Locational Factors RRe ort. The key factors regarding each of these topics are discussed below: a. Existing Land Use A study of the existing land use in Iowa City was completed in 1976 and the results were published in the 1976 Land Use Summary. Careful consideration of the existing an use pattern serves to provide continuity and to protect private investment, the city's architectural heritage, and existing neighborhoods. However, concern for increased environmental quality, efficiency, and fairness will require some adjust- ments to the established pattern. Some land use patterns are no longer valid as community needs have changed. Land uses once well suited to a particular location may now be incompatible with surrounding uses or the sites may be more appropriate for another use entirely. Iowa City's existing land use is mapped in the 1976 Land Use Summary and a discussion of land use compatibilT—tyis contained in the Land Use Concepts Report, both of which are set forth in Appendix A. r; ..•� DIICROFILn[O By 1 JORM MICROLAB 15 MluO1`11-•1ED BY JORM MICROLAB Land Use Findings c. 16 CEDAR RAPIDS AND UES MUINL'�, lUe'A b. Soils, Topography, and Vegetation Steep slopes and wet soils present limitations to urban de- velopment. Careful consideration must be given to the site planning process to minimize the development costs in these areas. Low coverage development is generally best suited to areas of steep slopes or wet soils. The generalized development limitations imposed by soil and topography are set forth in the Land Forms Guide in Appendix A. Crop land and woodlands are two vegetation types which influ- ence urban development patterns. The need to preserve areas of native vegetation, and to respect the productive role of prime agricultural land is well documented in the Vegetation Guide in Appendix A, and is discussed further in the Environ- ment section of this document. In the coming years, as prime building sites within the Gity are filled, it can be expected that pressure for development in areas of steep slopes, wet soils, and woodlands will in- crease. Core Areas Core areas are those locations where employment or shopping Opportunities are concentrated. These areas are major deter- minants of traffic patterns, housing demand, and demand for other public services and facilities. In Iowa City, the existing core areas are: the central business district/east University of Iowa campus, the health center campus, the Mercy Hospital/Central Junior High School area, the intersection of Iowa Highway 1 and Interstate 80 where American College Test- ing and Westinghouse Learning Corporation are located, the Lower Muscatine/First Avenue shopping area, the U.S. 6/Keokuk Street commercial area, the commercial area at the intersec- tion of Iowa Highway 1, U.S. 6, and U.S. 218, and the south- east Industrial Park. These core areas are identified in the 1976 Land Use Summary and the Locational Factors Report and are discussed in the Locations actors a ort, i -n Appendix A. rI.��-. MICROFILM[[) By • JORM MICROLAB L, vn: ,i r 0, L., M n 1411:ROFILMED BY JORM MICROLAB Trafficways CEDAR RAPIDS AND DES MUINLS, IUWA Land Use Findings Trafficways have a great effect upon city form and function. The relationship between trafficways and land use intensity is well established. Because of the need for ready access, intense land uses are generally located adjacent to major trafficways. As the level of access increases, land use intensity increases. Land uses which generate or attract larqe volumes of traffic are best located near the primary and secondary arterial system. Sites along the arterial system, with easy access to the external highway system, are sought for industrial and commercial uses which generate a signifi- cant number of semi -trailer truck trips. Major commercial centers which generate high volume automobile traffic also seek to locate along the arterial street system to increase accessibility and visibility. e. Physical Barriers Natural and man-made physical barriers influence the pattern of urban development by restricting utility extensions, and the vehicular and pedestrian transportation networks. Several barriers exist within Iowa City including the Iowa River, railroad lines, limited -access highways, portions of the University of Iowa campus, and several large parks, cemeteries and school sites. In some instances these barriers provide desirable buffers. However, the existence and location of these physical barriers has a direct impact on the location of land uses because the efficiency of utility extensions, popu- lation movement, and the provision of other community services is reduced when it is necessary to "go around" these barriers. f. Utilities Utility networks providing sewer, water, electric, natural gas, and telephone service are essential for most urban land uses. The potentials and limitations which utilities (par- ticularly sanitary sewers) present to urban development can be used in planning to identify areas of potential growth, areas which are at or near capacity, and areas difficult and inef- ficient to serve. The efficient provision of sanitary sewer service is closely related to watershed boundaries. Gravity flow sewers are most efficient in terms of capital cost and operating cost. The use of lift stations to pump sewage increases system operating costs and wastes energy. The new sewage treatment plant, which is programmed for construction immediately south of the existing city limits, will provide service to portions of the Willow, Ralston, Rapid and Snyder Creek watersheds. Certain areas within the city cannot be efficiently served by the sanitary sewer system. If developed, these areas should be in low intensity use such as low density residential (less than one dwelling unit per acre) or warehouse. MICROfl Ud[O BY JORM MICF44LAB 'i JAI,. is I10"il - 17 In MICROFILMED BY JORM 141CROLAB Land Use Findings Land Use Compatibility CEDAR RAPIDS AND ULS MUINLS, 106A Land use compatibility is based on the similarities or dif- ferences of the characteristics of land uses. Each land use type has specific site requirements in terms of topography, soils, access to transportation and utility networks, and lot size. Land use compatibility is also related to the levels and types of activity generated by a particular land use. Two bordering land uses with substantially different activity characteris- tics are likely to be incompatible. Incompatibilities arise over the side-effects of the more intense land use which do not stop at property lines. However, in many instances it is desirable to locate incompatible uses in close proximity. In these situations careful site planning at the boundary between incompatible uses is necessary to assure that negative side- effects of the more intense land use are controlled. Archi- tectural buffers (e.g., brick walls or wooden fences), or natural buffers (e.g., open space or natural screening) may be useful in such situations. LAND/CAPE WFnl U_ W Where it is not desirable to locate incompatible uses in close proximity, two buffering techniques are particularly useful. First, transitions between different land uses which take place across alleys and rear property lines are usually more successful than transitions along side lot lines or across streets. Second, an intermediate use which shares some of the characteristics and requirements of the adjoining uses provides a less abrupt transition from high intensity to low intensity uses. These concepts are further discussed and illustrated in the Land Use Concepts Report in Appendix A. h. Energy Energy savings can be realized by distributing land use to maximize use of the existing utility networks, streets, schools and other public buildings, and existing public services and facilities. Compact development of higher density residential and commercial development (as opposed to strip or spot development) will reduce dependency on the priv- ate automobile.

Future Land Use CEDAR RAPIDS AND ULS MOINLS, WWA Land Use Goals & Objectives Future land use needs are based on projected demands of residents, business and industry, and government. The Report on Population: Summary provides information on existing and future population trends. It is expected that Iowa City will continue to grow by approximately 500 persons per year and that, as the University population stabilizes, the proportion of those over 25 and under 18 will increase. By providing adequate, yet not excessive land for business, industry, housing, and other activities, moderate growth can be accom- modated, while the provision of utilities and other city services can occur in an efficient and economical manner. LAND USE GOALS &OBJECTIVES a. Goals 1. To provide adequate development opportunities while recognizing environmental constraints and citizen needs, through a multi -core development pattern guided by water- shed and other natural boundaries. 2. To maximize the locational suitability of land uses according to existing land uses, soils, topography, vegetation, distance from core areas, trafficways, physical barriers, and utilities. 3. To'provide an adequate choice of sites for existing and future development needs, which minimizes the negative impacts of incompatible land uses. 4. To achieve a land use distribution which encourages energy efficiency. b. Objectives 1. To consider existing land use in future development and redevelopment decisions. 2. To protect steep slopes, flood plains, woodlands, and similar areas of environmental concern. 3. To concentrate the most intense land uses in or adjacent to existing core areas. 4. To locate land use in relationship to distance from trafficways. 5. To utilize physical development barriers as transitions between incompatible land uses and to create order and predictability in development. 6. To coordinate urban development with the efficient exten- sion of sanitary sewers and other utility networks. 7. To minimize undesirable land use conflicts by providing adequate transitions between different land uses. 141 CR01'I LMLO BY JORM MICRbLAB LLSO:, Idd l • 'ii, '401'[1, 19 I ZO MICROFILMED BY JORM MICROLAS Land Use Policies CEDAR RAPIDS AND DLS MOINLS, IOWA 8.

Transit CEDAR RAPIDS AND ULS I.IUINL�, IUwA The operation of a mass transit system offers Iowa City an energy efficient and environmentally sound way of utilizing its investment in streets and roadways. By using buses, the trip -carrying capacity of arterial streets is dramatically increased, and congestion is reduced. Increased use of the transit system serves to alleviate parking problems in and near the downtown and other core areas. These problems also contribute to the deterioration of adjoining neighborhoods. Buses provide necessary transportation to low income resi- dents, students, the elderly, and other Iowa City residents who do not have ready access to private transportation. Many of the sample and general survey respondents were highly complimentary toward the present transit system. Eightyfive percent of the Peo lW s Guide and S_urveI respondents would like to live witFn one to four blocks of a City bus stop. wt 50 'RI NDS! Buses are more energy efficient than automobiles, and ef- ficiency can be increased as buses are more fully utilized. Currently, the transit system is under-utilized during the middle of the day and other off-peak hours, and on outbound Id1CRUILMED BY JORM MICR4�LAEI r - R R n M L; LIICROFILMED BY JORM LIICROLAB CEDAR RAPIDS AND UES MUINLS, 10WA Transportation Findings morning and inbound evening runs. Greater utilization of existing transit system capacity can be accomplished if major employers use flexible time or other adjustments to working hours. Additional transit efficiency can be gained by careful arrangement of the transit routes. b. Major Traffic Ways Numerous problems have been identified within the existing trafficways system of Iowa City. These include: congestion at river crossings; congestion and congested left -turning move- ments at major intersections; an inadequate number of cross- town arterial streets; inadequate capacity on several arterial street sections; inefficient access to several core areas; and unnecessary traffic routed through the downtown core. An improved trafficway system would serve to benefit passenger and delivery vehicle operation, and the operation of the mass transit system. A more complete discussion of these findings is set forth in the Trafficways Report in Appendix A. Residential Neighborhood Impact The negative impacts of major trafficways upon residential neighborhoods are, in certain locations, a major problem. During the citizen participation process, particular concern was expressed by residents, both in surveys and in meetings, concerning high level of automobile and truck traffic operat- ing through residential neighborhoods. These problems are caused by traffic "short -cutting" through residential neigh- borhoods on non -arterial streets, and by inadequate buffering between designated arterial streets and adjoining residences. d. Bikeways and Walkways i 141CROFILM[i) BY JORM MICR6LA9 I '40! ;! 23 r� 24 MILROFILMED BY JORM MICROLAB Transportation Goals & Objectives CEDAR RAPIDS AND ULS MUINLi, 10AA Bikeways and walkways provide basic transportation and rec- reation to the community. As a form of transportation, bi- cycling and walking are much more energy efficient than driv- ing a car. Additionally, they do not rely on dwindling supplies of fossil fuel power. Although the benefits of these energy efficient modes of travel are widely recognized, several constraints limit their full utilization. Conflicts with vehicular traffic make movement unsafe for pedestrian and bicyclists at many intersections and along several streets in Iowa City. The close -spaced grid pattern in the older areas of the community creates numerous conflicts between bicyclists and motorists. In new subdivisions, long curvilinear streets often have poor pedestrian and bicycle circulation character- istics. This topic is more fully discussed in the Trafficways Report and the Preliminary Bikeways Plan. TRANSPORTATION GOALS & OBJECTIVES a. Goals 1. To provide a balanced transportation system which allows for the safe, orderly and efficient movement of people and goods throughout the city. 2. To protect residential neighborhoods from the adverse effects of arterial traffic circulation. 3. To provide for efficient alternate modes of transporta- tion. 4. To increase use of mass transit, bikeways, and walkways. Objectives 1. To maximize utilization of the City's transit system. 2. To improve existing arterial streets, and to build new arterial streets to meet the needs of automobiles and mass transit, and to the extent possible, to build only in areas of low residential impact, in peripheral loca- tions, or to relieve negative impacts in residential neighborhoods. 3. To protect residential neighborhoods from the adverse affects of arterial traffic circulation and parking by effective use of design features and traffic control devices and regulations. 4. To provide appropriate facilities for bicycles and pe- destrians, so that these forms of travel may be utilized as alternative modes of transportation, as well as healthful forms of recreation.

In order to minimize these problems, and achieve the goals and objectives set forth above, the following recommended actions should be taken: a. Transit 1. Arrange routes so they end at employment centers when possible. 2. Provide higher level transit service in corridors where the higher level service will reduce traffic congestion by reducing the use of private automobiles. 3. Develop a program which will maximize the use of transit and reduce the needs for long-term parking in the down- town area. 4. As soon as ridership levels and financial capability permit, provide increased frequency and hours of service. 5. Provide transit service such that ninety percent of the population is within three blocks of a bus stop. b. Major Trafficways 1. Improve traffic flow at signalized intersections where needed to reduce congestion or unsafe conditions. 2. Designate and develop a truck routing network in and around Iowa City which, to the maximum extent possible, routes trucks on major arterial streets around, rather than through, residential areas. C. Residential Neighborhood Impact 1. Where necessary, use traffic diverters to discourage through traffic in residential neighborhoods where through traffic is creating unusual adverse impacts. 2. Buffer new, developing and redeveloping residential land uses from arterial traffic by extensive use of trees and other landscape buffers. 3. Develop a parking system in neighborhoods adjoining the downtown and other core areas to discourage commuter parking. d. Bikeways and Walkways 1. Adopt and implement the Bikeways Report and Plan. 2. Establish standards for walkway and sidew_a1k7_evelopment in residential subdivisions. 3. Improve, where necessary, sidewalks in areas of high pedestrian activity, near schools, near the downtown, and near other shopping areas. �;dICROFILMED BY JORM MICR46LAB '!0131. `. 25 E 26 MICROFILMED BY JORM MICROLAB Transportation Policies TRANSPORTATION POLICIES CEDAR RAPIDS AND UES MUIPIE), IUWA In order to promote the purposes of this Plan, end achieve the Coals and Objectives set forth above the following policies are recommended.

Economic Development Because much of Iowa City's land is State-owned and non- taxable, Iowa City's tax burden rests more heavily on resi- dential property. When compared to other cities of similar size, Iowa City has a larger proportion of total property valuation in residential property, and a smaller proportion in industrial property. Enrollment projections for the University of Iowa, show a leveling off and actual decline after 1980. Not only will this affect the amount of retail trade in Iowa City; it may reduce new employment opportunities within the University. It is important, therefore, for Iowa City to reduce its economic dependence upon the University of Iowa by attracting new industries and other major employers. In mid -1977, the City Council began exploring economic development potential. The firm Zuchelli, Hunter & Associates, Inc., was retained to undertake a brief study of Iowa City's economic development potential. An economic development program is to be estab- lished during fiscal year 1979. Most People's Guide and Surve respondents favored attractingm vers tyy-oriented industry (83.6%), medically -oriented industry (83.4%) and other light industry (71.2%). Respondents emphasized that only non-polluting industries were favored. C. Neighborhood Commercial The use of neighborhood commercial centers to provide many basic retail needs such as food, hardware, or pharmaceuticals, 27 141CR0(ILId10 By DORM MICR+LAB 28 mILROFILMED BY JORM 141CROLAB CEDAR RAPIUS AND DES NOINLS, IDvIA Economic Findings is an alternative to concentrating these retail activities in larger commercial centers. Convenience stores and offices in residential neighborhoods were favored by most Peo less Guide and Survey respondents (70.6%). Analysis of neig orhooc- commercial centers suggests that, if properly designed and regulated, these centers would not be disruptive and could be very beneficial by saving residents' time and energy. These stores significantly contribute to the reinforcement of a neighborhood concept within the city. The neighborhood con- cept is specifically addressed in the Land Use Concept Report in Appendix A. NEIGHBORHOOD CONVENIENCE CENTER DESIGN J urauL I J 1 a atavict iMIIOWTIar Soufn: Redrawn from Land subdivision Regulations, Housing and HomefinannAgenm Washington, O.C. The largest of Iowa City's core areas attracts as many as 10,000 employees per day. At present the majority of em- ployees and shoppers travel to these core areas by automobile. When business and industrial activity are concentrated into cores, they are much more easily served by alternative trans- portation modes. Maximizing the population within walking or bicycling distance from shopping and employment opportunities will decrease dependency on the automobile. `' *y MICRO[lua(.o 9r JORM MICR¢LAB !: i.

Schools and parks, for example, are owned and operated by separate entities. Facil- ities operated by one jurisdiction could at times be utilized by another jurisdiction to great advantage. Additionally, because of many similar locational requirements, the joint development of schools and parks is frequently beneficial. " FINDINGS a. Joint Facilities ,-, Benefits of joint development and use are evaluated in the Community Facilities Report in Appendix A. The joint develop- ment and use of commu m ty facilities offer greater return for the investment. Shared costs of structures and site develop- ment, and shared use allow for fuller utilization of facil- ities. For example, if properly designed, a school gymnasium can be open to the public for evening recreation. b. Parks N Iowa City's park system consists of 28 parks totaling approxi- mately 500 acres. The Community Facilities Report includes r MICROfILMEB BY DORM MICR46LAB I . ^fF%!' 31 rlI,ROFILMLD BY JORM MICROLAB Community Facilities Findings CEDAR RAPIDS AND ULS hlUlliL_,, i"" information on the type and location of each park, and at which parks recreation equipment and areas are provided. The report includes national park development standards which, if applied to Iowa City would indicate a shortage of park land. However, Iowa City's needs for park land are somewhat unusual because of the University population and facilities, and because of the facilities provided at the Coralville Reser- voir, Lake Macbride and Kent Park. Of the People's Guide and Survey respondents, 59.6% felt additional recreational facil- ities should be funded. The Community Facilities Report and the Iowa River Corridor er StyLdI Stanley Consultants 1975-76) recommend incorporating into the parkland system areas of environmental concern, riverfront property, and flood detention sites. In the People's Guide and Survey, 62% of the respondents answered that improving the Iowa River and riverbank should be a City - funded project. Linear parks, including bikeways and walk- ways, provide improved access between facilities. As Iowa City continues to develop, new neighborhood and com- munity parks will be necessary. In order to ensure the avail- ability of parks in suitable locations to serve neighborhood needs, other communities require mandatory dedication of park land, or payments -in -lieu of dedication as residential land is developed. Iowa City could require mandatory dedication of park land or fees -in -lieu of dedication if certain standards are prescribed and met. Iowa City could also have a minimum open space requirement for all new subdivisions. Such open space could either be dedicated to the City or maintained and owned by a Home Owners Association. Libraries and Cultural Activities For a community of its size, Iowa City has numerous cultural and learning opportunities in addition to the public school system. The Iowa City Public Library and Recreation Center are City -owned facilities; most others are part of the Uni- versity of Iowa. The Iowa City Public Library is currently MICR0EILMED BY ' JORM MICRbLA6 MILIM ILMLD BY JORM MICROLAB • CEDAR RAPIDS AND ULS MUINLS, IUvIA Community Facilities Findings housed in a building with approximately 23,000 square feet of n floor area. This facility is no longer capable of accommodating increased demand; additional space for shelving, staff and seating is needed. At present, the building is located on six levels and is inaccessible to the handicapped. Results from the People's jGuide and Survey showed strong support (62.2%) for expanding IlDrary facilities. There was also citizen support for large and small meeting and lounge areas for resting, reading, and socializing in the downtown area. d. Police and Fire Protection The Police Department has serious space deficiencies in its present facilities. The Police Department, which occupies a total of 5,426 square feet in the Civic Center, lacks inter- view rooms, adequate laboratory facilities, adequate storage space, sufficient booking and receiving area, and a private .. O area for polygraph operations. Iowa City's Fire Department received a Class Four rating by the Insurance Services Offices of Iowa which compares very favorably with other Iowa communities. The only problem identified in the Comm(MjjX Facilities Report was inadequate apron area for the main fire station. Iowa City now operates three fire stations: one centrally located, one to the southeast, and one to the west. As com- munity growth continues, the City will need to continuously evaluate -response time and equipment and man -power adequacy to ensure continued fire protection at the existing level. e.

The study also concluded that the Civic Center has several distinct locational advantages, including building expansion potential and publicly -owned land nearby. h. Utilities A discussion of the public utility systems in Iowa City is presented in the Report on Utilities in Appendix A. Areas which can be provided sewer service by the existing system are identified in this report. A new sewage treatment plant is included in the Capital Improvements Program, and a site for the sewage treatment plant has tentatively been selected. Upon the completion of the new sewage treatment plant addi- tional areas within the city can be sewered. However, con- struction of a new sewage treatment plant will not fully resolve Iowa City's sewer system problems. Additional sewer system improvements will be required in the years ahead, in order to fully realize the potential offered by the new sewage treatment plant. The Iowa City water treatment plant capacity is more than adequate for meeting peak demands and should be capable of meeting future demands to the year 2000. The ability to efficiently provide utility service, particu- larly sanitary sewer service, is a primary determinant of future growth areas within the city. This is more fully explained in the Locational Factors Report in Appendix A and the Land Use section'— above. Specific sewer system improve- ments are addressed in the Growth Sequencing section of this Plan.

Existing Needs/Situation The Iowa City housing market is characterized by: very low vacancy rates for rental housing; relatively high housing costs; single-family dwellings which have been converted to multi -family dwellings without adequate provisions for parking and open space; and fairly low density development of apart- ments and single-family dwellings throughout the city. The Report on Housing and the Citizen Participation Report in Appendix A provide additional information on this topic. Housing is of particular concern to city residents as ex- pressed in the People's Guide and Survv� responses and at neighborhood meetings. ATT—res�ents desire safe, affordable housing. Single-family home owners typically perceive the inclusion of rental or multi -family properties in their neighborhoods as undesirable, yet both groups frequently demand housing in the same area.

Ph!;-' • A', MiLRUFILMEU BY JORM MICROLAB CEDAR RAPIDS AND ULS MUINLS, UYJA Housing Findings Alternatives/Single-Family Dwellings The traditional single-family detached dwelling has become prohibitively expensive for many Iowa City families and in- dividuals. The supply of quality low cost single-family housing is limited. Current building costs, and zoning and other development regulations contribute to the high cost of housing. The City can have a direct effect on the provision of low cost housing through zoning, and development regulations. Garden homes, townhouses and mobile homes are three forms of single- family housing which could be encouraged. Garden homes are built on relatively narrow lots with one building wall located on one lot line with the other side yard at least ten feet in width. Because lots are smaller and utility and street improvements per lot are reduced, signif- icant savings in land development costs can be realized. The y traditional single-family neighborhood character is, however, retained. Townhouses are distinguished by common walls connecting several individual units, and minimum lot sizes. Only end units have side yards, though all units have front and rear yards. Townhouses represent the maximum density for single- family housing. Land development costs are minimized and building costs are reduced (due to common walls). Garden homes and townhouses are further discussed in the Report on Housing in Appendix A. Mobile homes are the form of single-family housing with lowest costs. Mobile home owners would like the choice of purchasing their lots in a mobile home subdivision or renting their lots in a mobile home park. C. Housing for Special Groups Housing for the handicapped, the elderly, students, and other special groups is necessary within any community. The State of Iowa requires that apartment complexes with more than four units have one or more units which are accessible to the handicapped (a sliding scale is used). Subsidized elderly housing will be significantly increased in the near future with the construction of two new complexes within and adjacent to the downtown. Approximately 47% of the University of Iowa student population is housed in dormitories, married student housing, frater- nities, or sororities. The rest must find housing elsewhere. This has created a high demand for low cost rental housing near the University campus. 39 MICROFILMED BY ' JORM MICR6LAB 40 MII:ROFILMED BY DORM MICROLAB Housing Findings Housing Location CEDAR RAPIDS AND UES MUINLS, !UWA A number of factors influence housing location, including: distance to core areas (areas where employment, education, or shopping opportunities are concentrated); availability of City services such as sanitary sewer, water, schools, and parks; location of hazards or nuisances such as highways, railroads, heavy industry, or extraction operations; and environmental factors such as floodplains, valuable agricultural land, topography and vegetation. Generally, the highest density housing is best located adjacent to core areas, where adequate city facilities and services exist, and on areas of relatively flat topography. Low density housing is suited to all types of topography, and requires the provision of less intense city facilities and services. Residents of low density housing generally prefer to be away from core areas. All housing should be some distance from hazards and buffered from nuis- ances. Though there has been a consistently high demand for low cost housing near the University, other renters prefer different locations. This is not to imply that multi -family units should be mixed with single-family. Instead, multi -family units can be successfully integrated in neighborhoods as transitional uses between neighborhood commercial areas and single-family residences. Housing Rehabilitation Housing rehabilitation maximizes the potential use of the existing housing stock (often resulting in low cost housing), serves to maintain the character and function of existing neighborhoods, and frequently serves to preserve the City's architectural heritage.

In some instances, these homes may be moved to new locations or converted to multi -family residences. f. Neighborhood Preservation The preservation of Iowa City's older neighborhoods is of major concern to many residents. The homes in these neigh- borhoods, some of which are architecturally and/or historic- ally significant, have contributed much to the city's char- acter. Many of the homes have been converted into multi- family units or torn down and replaced by apartments. Scattered apartments within established neighborhoods tend to disrupt activity patterns and weaken neighborhood identity. In addition, existing City facilities may be inadequately sized to efficiently meet the needs of multi -family use. Some homes will deteriorate to the extent that it is no longer economical or practical to retain them; other homes may be destroyed by fire or similar disaster. Garden homes and townhouses, as replacement for groups of single-family houses, provide economical alternatives for retaining the single- family character of a neighborhood. 41 41CRo1 iu+11) By JORM MICRmLAB MICROFILMED BY JORM MICROLAB CEDAR RAPIDS AND US MWILS, WAA Housing Goals 8 Objectives 42 g. Housing and Site Design Criteria and Energy Conservation Good housing design is a benefit to the community in general. Not only does it help people to live comfortably and in a pleasant environment, but it can also help to reduce housing deterioration, energy waste, and psychological stress. Privacy is essential to good housing design and was expressed as second only to cost in satisfying housing needs of the respondents to the People's Guide and Survey. Noise buffering between attached residential units, and fencing of yards are two convnon methods of increasing privacy in residential areas. Proper site orientation not only increases privacy but also conserves energy. The addition of landscaping can further decrease energy needs by providing shade in summer and insula- tion in winter. The Vegetation Guide in Appendix A provides additional information on the benenits of urban vegetation. Enjoyable private open spaces for each dwelling are energy efficient because they reduce the need for leisure auto trips. Most multi -family units are lacking in open space and other amenities. HOUSING GOALS & OBJECTIVES a. Goals 1. To provide a variety of housing types which will meet the needs of city residents. 2. To meet the needs of both renters and owner -occupants in housing development and redevelopment. 3. To encourage the maintenance, and where necessary, the rehabilitation of the existing housing stock. 4. To preserve the character of established neighborhoods where desirable and possible. b. 2U!Lc 1.

C-' k., MICROFILK D BY JORM 141CROLAB CEDAR RAPIDS AND OLS MUIML�, IJAk I Environmental Findings ENVIRONMENT FINDINGS Fragile Environmental Features Iowa City has a number of natural features which are environ- mental, aesthetic and recreational assets to the city. These features include the Iowa River, bottomland woods along the streams, and steep wooded slopes, all of which provide en- vironmental variety. Upland woods, associated with steep slopes, provide opportunities for parks, conservation and very low density residential uses. The Storm Water Management, Flood Plain, and Tree Ordinances are means of protecting these features. Conservation of natural areas was viewed as the highest priority item by citizens responding to the People's Guide and Survey (85%). Seventy-three percent of those i' stating that conservation of natural areas should be funded were also willing to pay more for existing services in order to fund such projects. The ecological importance of maintain- ing a diversity of natural systems, which provide for a large variety of plant and animal life, is explained in the Vegetation Guide, in Appendix A. b. Natural Stream Corridors The flooding of Ralston Creek has been a serious problem in Iowa City for a number of years. As development takes place within the watershed, the additional impervious surface area increases run-off and compounds the flooding problem. Flood- ing is a potential hazard as development occurs in other watersheds, also. The stream channels form natural corridors which, if left as greenbelts, serve to reduce the effect of heavy run-off from adjacent development by maintaining the natural floodway and flood plain to transport and hold water. Vegetation on the banks of stream channels minimizes erosion, and varying soil types permit diverse vegetation and wildlife habitats. Bottomland woods, associated with stream valleys, are well suited for development of linear greenways through the city and as storm water detention facilities. In ad- dition, construction in the flood plains is costly, making flood plain land more suitable for low intensity uses. c. Soils and Topography The Landforms Guide details the variety of soil types in Iowa City. Soil requirements vary for different land uses; poorly drained soils with high moisture retention are unsuitable for intensive land uses but can be used for low density develop- ment. Similarly, steep slopes create construction difficul- ties and erosion hazards. Details concerning these factors in 45 * I41CRof ILMED BY JORM MICR6LAH 141t,ROFILMED BY JORM MICROLAB Environmental Findings M CEDAR RAPIDS AND DES MOINES, :O'NA Iowa City are contained in the Landforms Guide and Locational Factors Report, in Appendix A. d. Edge Effect of Open Space Urban land uses especially continuous, contiguous develop- ment create large tracts of land devoid of both diversity and the natural systems necessary for a healthy, stable environ- ment. The result is pollution, psychological stress and a degraded environment. The Johnson County Regional Planning Commission's Land Use Plan for the Metropolitan Portion of Johnson Count , Goals and bjectives nd for Parks, Recreation apen Space 1976 Update) recommends a system of greenways connecting neighborhoodsto schools and open space, and a linked network of open spaces along the Iowa River and other stream corridors. Parks, recreational areas, and open spaces which are located so that their exposure to public activity isaximblic. ZLineareparks or greatest number of benefits to the pu greenways provide for a very large area of contact between open space and urban uses and therefore have a great edge de effect. When these facilities border streets, they p rovi relief from continuous urban development, and expand the natural effect at transitions between open space and other uses. These benefits are greater per unit area of open space when open space areas are linear and have irregular boundaries. In addition, a linear park or greenway provides a buffer between land uses on each side. This buffer provides not only visual relief but also reduces noise and air pollution. 141CROFILMED BY 1 JORM MICR6LA6 e milLRUFILMED BY JORM MICROLAB CEDAR RAPIDS AND ULS MOINL�, iU'04\ Environmental Findings e. Urban Quality r' As the city grows and develops, noise, water, and air pol- lution increase, and areas of open space and vegetation which help to alleviate these pollution problems decrease in size and number. In both the Special Surve and the People's Guide and Survey, many residents expressed concerns about increasing pollution particularly of the creeks and the Iowa River. The main sources of pollution of the Iowa River are run-off from fields and feed lots upstream, dust and rock particles from extraction sites, inadequate sewage treatment facilities and solids from the water treatment plant. Run-off from traf- ficways and, in winter, salt from the streets also contribute to pollution. Increased storm water run-off due to urbani- zation contributes to the inadequacy of the sewage treatment Plant. The effluent from this plant does not meet EPA stan- dards (See Sanitar Sewerage System FacilityPlan, Pt. I, Veenstra & Kimm {,� Air pollution in Iowa City is caused mainly by automobiles, trucks, and coal burning systems. Noise pollution in Iowa City is caused mainly by motorized vehicles and machinery. The effective noise level increases with the decrease in buffering vegetation. As shown in the Tree Planting Plan, trees effectively reduce sound levels by blocking, reflecting and absorbing sound waves. All types of vegetation also reduce air pollution by absorbing gaseous pollutants and mechanically filtering dust particles. (See Ecological, Environmental and Engineering_ Uses of Trees.) f. Energy The response to the People's Guide and Survey was strongly in favor of energy conservation measures. Eighty-six percent of the respondents said the City should enact energy-efficient construction requirements, 69% wanted the city to support home Q insulation programs, and 57% indicated an interest in in- stalling solar heating and cooling systems in their houses if low interest loans were available. 91% supported recycling programs which conserve energy and reduce litter. The in- creased use of mass transit and bicycles for energy conser- vation and to help reduce air pollution was also supported. y o ENERGY 11 VA MICROFILIdCn By JORM MICRbLAB '1n,:;'. r'1ICROFILMED BY JORM MICROLAB Environmental Goals b Objectives CEDAR RAPIDS AND UES MUINES, 10'v4A The amount of solar energy available for daily use is over 10,000 times the amount of fossil fuel energy we currently use on earth. By development and wide application of new solar technology, we can not only assure ourselves a reliable source of power, but we can more closely fit into natural energy processes and reduce pollution. There are also other sources of energy such as wind, hydro -electric, and methane gas pro- duced by burning trash, which can reduce the need for fossil fuels. The cycle of solar energy use is described in Ecological, Environmental and Engineering Uses of Trees: Energy Conservation which is available from the Iowa City Department of Community Development. Appropriate site orientation and landscaping can be used to conserve energy in buildings as described in the Tree Planting Plan. ENVIRONMENTAL GOALS & OBJECTIVES a. Goals 1. To provide a stable and healthful urban environment for all residents, which is in harmony with the surrounding natural and agricultural environments. 2.

HUMAN NEEDS The human needs/services planning element of the Comprehensive Plan is being prepared by the Johnson County Regional Planning Com- mission in cooperation with the Department of Community Develop- ment. As with other elements of the Comprehensive Plan, informa- tion on existing services was gathered first (this involves City, county, and State-wide services). Information on citizens' needs was obtained through surveys, meetings and from various agencies. The Human Needs Plan will be completed in 1979 and will be adopted as a separate Comprehensive Plan element at that time, following public hearings. 51 FILMED BY ' JORM MICR#LAB CL AP R 1':k. • JL. - '101'�I S 9 r41CROFILMED BY JORM MICROLAB NEXT SEQUENTIAL DOCUMENT/FILE MISSING CEDAR RAPIDS AND UES MUINLS, IUWA JORM MICR4)LAB TARGET SERIES Y9 � SEQUENTIAL .._........ .

Explanation of Map JOFiM MIGROLA6 r� n MICRUf1LMEU BY JORM MICROLAB CEDAR RAPIDS AND UES MUINU, IUvii" EXPLANATION OF THE MAP The overriding concept in preparing the new Iowa City Land Use Map has been to encourage compact development within portions of the Willow, Ralston, Rapid and Snyder Creek Watersheds. MUDDY CRLfK CLE IOYlA�. _l CRICK'. � -Ji RALSTON •' __ fNYDER\ CREEK C1D77 OLD K1" D77 MANS n e.. urs CREEK WATERSHEDS These areas can be efficiently and economically served by the proposed sewage treatment plant, and other city services and facilities (existing or proposed). In addition, the provision of parks and open space, including linear greenways, and the alloca- tion of development intensities will serve to protect the environ- mental quality and to assure a healthful environment. The area of the Map within the limits of urban growth is the focus of this Plan. This area, if fully developed and redeveloped, could represent a total population of 95,000, which would be an increase of 45,000 over present population. This amount of growth is not expected to take place within twenty (20) years (projections sug- gest the growth of 500 persons per year should be expected.) Areas of increased densities are not likely to be developed or rede- veloped completely within a twenty (20) year time frame. Conse- quently, many areas will be lower in density during the twenty (20) year period than the Map indicates. Meanwhile, undeveloped areas will provide greater location opportunities for developers and home -buyers. The accompanying sequencing map is based on the cost of providing trunk sewers to potential development areas. The order in which water and sewer service is extended to parts of the city will MICROf ILV1GD BY • JORM MICR6LA9 53 54 MIL'ROFILMEU BY JORM MICROLAB • CEDAR RAPIDS AND ULS MUiNL'o, iUNA direct the sequencing of growth and development. Included in Appendix B are the expected population increases for various areas of the city, and descriptions of the proposed facility sites to serve the new population. The Land Use Map emphasizes development capability. The capability is determined by the ability to provide utilities, by environmental factors, and by existing uses. The ability to provide sanitary sewers is an important factor in determining residential density for the areas within the city. There are some areas on the far west side (west of Mormon Trek Boulevard and south of Melrose Avenue) where the ability to provide sanitary sewer service with existing facilities is questionable. A study by the Public Works Department, now underway, will determine the existing capacity and provide recommendations for serving this area. Areas of steep slopes, flood plains or significant vegetation are designated for low intensity use, or as open space. High intensity uses (i.e., commercial and industrial) are located on major streets and near existing core areas. Where possible, low density residential uses are located away from heavily traveled streets, industry and com- mercial activities to minimize conflicts. Some of the locations for recommended use on the map are approxi- mate; circles and rounded edges are meant to imply that boundaries and locations are not definite for neighborhood commercial areas, parks or park/school sites. A set of locational criteria is pro- vided elsewhere in the text to define appropriate locations for these flexible land uses. The Land Use Map indicates generalized land uses; individual sites for some land uses have not been specifically identified. A cate- gory of land use on this map may include up to four zones on the zoning map. In a single category for residential use, there may eventually be zoning which allows townhouses, duplexes, four- plexes, small apartment buildings and mobile homes. These cate- gories have been designed to portray intensity and density rather than specific use. Further discussion of the land use categories and locations follows. RESIDENTIAL The Land Use Plan generally preserves existing residential uses while providing greater opportunity for high density housing close to the University of Iowa and alternative forms of single-family dwellings throughout the city. Although the majority of land designated for housing is for single-family use, (in keeping with existing demand), development alternatives are provided for, and low cost housing is encouraged. RICROFILI41O By JORM MICR1LAFI MILJWFILMED BY JORM 141CROLAB CEDAR RAPIDS AND DLS HUINL:,, INA 25+ Dwelling Units Per Acre Highest density housing opportunity (25+ DU/A) is provided north and south of the Central Business District (CBD), adjacent to the eastern edge of the University of Iowa campus, and between Newton Road and U.S. 6/218. The University of Iowa, Veterans and Uni- versity Hospitals, and the CBD are the largest core areas in terms of employees, students, patients, and shoppers. Locating high density housing in these areas would be convenient for residents, and would increase efficiency and energy savings by encouraging pedestrians and shortening travel distances between places of employment, classes and residences. City services and utilities can be adequately provided and the areas are located adjacent to arterial or collector streets. Limited commercial activity will be permitted in some areas within this use category. 16-24 Dwelling Units Per Acre Moderately high density housing opportunity (16-24 DU/A) is pro- vided east of the CBD, in the Benton Street/Greenwood Drive area, north of Towncrest, along North Dodge Street and in several other locations generally along collector or arterial streets. This land use density includes townhouses, low-rise apartments (three stories or less), and mobile home parks and serves as a transitional use between high density housing and/or commercial areas, and moderate density housing (garden homes, townhouses and mobile home subdi- visions). These areas are located near core areas to encourage economical redevelopment in some cases, or to provide choice for renters. 0 56 M1640FILMED BY JORM MICROLAB CEDAR RAPIDS AND ULS MUINL�, 1044 8-16 Dwelling Units Per Acre This land use area is the highest density single-family category and also includes low density multi -family uses. Garden home, townhouse, and mobile home subdivisions and parks are the principal forms of development. These uses are located in several areas throughout the city, but are generally closer to core areas than the 2-8 DU/A density. Residential development of 8-16 DU/A is also used as a transitional use between apartments and low density single-family housing. These areas are located to encourage eco- nomical development or redevelopment of single-family neighbor- hoods, to provide choice for home -buyers, and to allow mobile home subdivisions. Planned Unit Developments in this use category provide opportunity for the inclusion of traditional single-family detached dwellings, and apartments if the overall density is main- tained. 2-8 Dwelling Units Per Acre Land use density of 2-8 dwelling units per acre includes tradi- tional detached single-family dwellings and garden homes. Areas of this density are provided throughout the city, generally away from commercial and industrial areas, and major trafficways. Buffers, indicated by green strips, are shown where these residential areas ;dICRUFi LIdf.D BY JORM MICR6LA6 M M n M;LRUFILMED BY JDRM MICROLAB CEDAR RAPIDS AND ULS MUHILI), LU'm, and incompatible uses adjoin. The use of Planned Unit Developments in this use category can provide opportunity for the inclusion of townhouses and apartments if the overall density is maintained. Less Than 1 Dwellinq Unit Per Acre Very low density housing opportunity (less than 1 DU/A) is provided in the area north of I-80 and in the area west of the University of Iowa land and north of Melrose Avenue. These areas cannot be efficiently served by sanitary sewers. Existing woodlands provide an attractive setting for residential dwellings. This area pro- vides housing opportunity for those who might otherwise choose to locate in rural areas of the county. Agricultural land will be saved and potential interruption of farming operations minimized. The size of individual lots will depend upon soil type as the dwelling units will require on-site sewage disposal systems. The cost of providing police and fire protection and road maintenance to this area will be higher than average. J Land Use Intent for Special Areas Because the Comprehensive Plan Land Use Map is generalized and certain land use designations may include a number of different zones, specific use is recommended for certain special neighbor- hoods of Iowa City. Reasons for these recommendations are given in detail here, so that future Planning and Zoning Commissions and City Councils will have a record of the intent of the present City Council when this Comprehensive Plan was adopted. 57 MICRDf ILMCD BY JORM MICR+LAO M MILROFILMED BY JORM MICROLAB CEDAR RAPIDS AND UES FIUINLS, ;OwH Advances Drainage Systems Site This area bounded approximately by Sheridan Avenue, the rail - Ralston Creek is shown ata e) road, Maggard Street and on the dential density of 8-16 DU/A (dwellings unisurts roer undedby Land Use Map.

Generally it is the intent of the Plan that governmentally owned land will eventually be shown as within a Public Zone, while privately owned land will be given a zoning designation appropriate to the use on the land surrounding it. Parks and Open Space Parks and open space are an integral part of this Land Use Plan. These areas are generally located in woodlands, along streams, or along ridg tops. These areas provide linear greenways throughout the city (generally along streams), visual relief to intensely developed urban areas, opportunity for outdoor recreation and education, wildlife habitat, and similar land use opportunities. Park and open space areas may be publicly or privately owned. Examples of privately owned open space include: country clubs, G golf courses, and common open space in Planned Unit Developments. Parkland is assigned at the ratio of twelve acres per 1,000 pop- ulation and is divided among several categories of parkland. Four types of parks are recognized: playgrounds, neighborhood parks, community parks, and city-wide parks. Standards for these parks are described in detail in the Community Facilities Re ort. Gen- erally, five acres per 1,000 population have been a ocated to playgrounds or neighborhood parks, and seven acres per 1,000 pop- ulation have been allocated to community or city-wide parks. New parks are represented on the map by dots (see legend). The size of the dot approximates the size of the park. The majority of existing city residences are within one-fourth mile of some type of park or school playground. Large lot single- family residences have less need for play areas within walking distance. In high density residential developments where adequate yard areas do not exist, the need for neighborhood parks nearby is greatest. Another factor which affects park land distribution is accessi- bility. Heavily travelled streets and highways, railroads, streams and similar barriers can limit the area considered "within walking distance". Parks are generally located away from heavily travelled streets, highways, and intersections. However, parks should be designed to maximize exposure to collector or local streets. In this way, the greatest number of residents can enjoy the open space provided, as the park is visible to all who go by. Parks which border rear lot lines of residences are undesirable as they provide the open space benefits to relatively few. Greenways are shown along the Iowa River and other streams. Along streams, the greenways will vary in width depending on flood plain Wj 141CROF 10119 By JORM MICR(yLAB '..i!iio, PUJ MILItOYILMED BY JORM MICROLAB CEDAR RAPIDS AND DLS MUINL_�, 1UNA size.

Three new neighborhood parks are proposed or immediately adjacent to existing residential areas where it has been determined that deficiencies exist.

Projected population figures and the assumption that elementary schools should bercentilizedlocated etern minerelaapproopriatetheir generalservice locations. mine appropriate School/park sites are dependent upon population distribution. Elementary schools are located to serve neighborhood units of approximately 6,000 persons and are on local streets. Junior highs are located to serve a number of neighborhoods and are on collector or arterial streets. The park/school sites will remain as open space until development occurs. Park development will generally occur concurrent with development of the area; schools will be built when and if they are needed. The sites will be sized so that adequate parkland will remain if the schools are built. This implies that excess parkland will be held for some time; it should be considered an economical alternative to a limited or non-existent choice of school sites at a future date. If a site is not needed for a school, it may be utilized for another public facility such as a fire station. Elementary school/park sites are located: on the peninsula; along Willow Creek south of Benton; along Willow Creek west of West High School; west of Wetherby Park; east of the proposed sewage treat- ment plant; southwest of Bon -Aire Mobile Home Park; and north of Hickory Hill Park (along the extension of First Avenue north).

Public and Semi -Public Buildings Existing public and semi-public buildings shown include: govern- ment offices and buildings, the Recreation Center, Veterans and ry Mercy Hospitals, and the National Guard Armory. Public and private schools, and the University of Iowa are not included in this cate- gory. Due to the general nature of this map, the City Library, the existing sewage treatment plant, churches, and private clubs are not shown. New publ;c facilities will include a City Library in the Central Business District, an east side fire station/water storage tank on Rochester Avenue, and a new sewage treatment plant on South Gilbert Street. Other new uses may include government office and facility expansion. University of Iowa All properties under the control of the Board of Regents of the University of Iowa are included in this category. AGRICULTURE The areas depicted as agriculture on the map are to remain as such for years to come. The preservation of prime agricultural land south and east of the city limits is consistent with National, State, and County government policy. In some instances, however, fiscal considerations may dictate development of limited areas of prime agricultural land which can be efficiently provided with municipal services. In areas shown as Agriculture on the Compre- hensive Plan Land Use Map, residential development at a density of one dwelling per acre or less may be permitted where the land is unsuitable for agriculture. COMMERCIAL Neighborhood Commercial The majority of new commercial areas will be neighborhood commer- cial centers. The locations shown on the map are approximate. These centers are located on one corner of the intersection of two arterial streets or the intersection of an arterial and a collector street. 61 �141CROI ILMGO BY 1 JORM MICR6LAB i i aU: F.df '10:'.6. m100 IL14ED BY JORM MICROLAB CEDAR RAPIDS AND ULS MOINLS, Wvri The size, number, and types of retail establishments included in the center will depend on the size and type of population to be served. The centers shown on the map would eventually serve around 8,000 to 10,000 neighborhood residents. A grocery and drug store would generally be the main tenants of a neighborhood center. (Single stores or very small centers could be included in Planned Unit Developments, but are not shown on the map.) A laundromat, barber or beauty shop, gas station, offices, and even a branch library could also be included. Gross floor area would usually range from 30,000 to 75,000 square feet. Standards for location, design and hours of operation of these stores are included in the Zoning Ordinance. These standards are designed to protect neighboring uses from potential conflicts. General Commercial General commercial use is provided in existing core areas and in one or two other existing locations. The number of commercial areas is limited to maximize efficiency and to minimize impact on residential neighborhoods. Department stores, apparel and acces- sory shops, office supplies and restaurants are examples of general commercial activities. Adequate opportunity for additional general commercial development exists within these areas. js The majority of new general commercial development will occur in the Central Business District as a result of recent urban renewal activity. Several new stores, a hotel, and office space will be added. Commercial expansion may occur south of the U.S. 6/Keokuk Street commercial area, northeast of the Lower Muscatine/First Avenue commercial area, and between South Riverside Drive and the Iowa River north of U.S. 6. Office Commercial Office commercial uses include professional offices such as doc- tors, dentists, and lawyers. The greatest demand for additional office space is in the Central Business District and adjacent to Mercy Hospital. Office space in the CBD can occur in conjunction with the general commercial area. New areas for office space in the area surrounding Mercy Hospital have been indicated. A four square block area east of the city Civic Center/Recreation Center complex has been designated for office use, as has an area near the Highway 1/Interstate BO interchange. Small additional amounts of office space may occur in neighborhood commercial areas or other general commercial areas. Land Consumptive Commercial (Warehouse) Land consumptive commercial use includes wholesale or retail busi- nesses and some light industry which require large amounts of land. -+7 Y ;d ICRUILMCD BY 1 JORM MICR46LAEI .m MICROFILMED BY JORM 141CROLAB CEDAR RAPIDS AND DES M011'1L�), IUWA Auto dealerships, construction yards, and building suppliers are examples of this type of use. The land designated east of the Iowa River provides opportunities for expansion. The area southwest of the airport along Highway 1 and U.S. 218 provide the greatest area for potential land consumptive commercial development. Access roads will be constructed along Highway 1 and U.S. 218 as needed. Highway Commercial Areas for new highway commercial uses (motels/hotels, restaurants, and a gas station) will be limited to one quadrant of the Highway 1 -relocated U.S. 218 interchange. INDUSTRIAL Office Research Park Office research park areas are located at the Dubuque Street and Highway 1 interchanges with I-80. These sites provide excellent access to the Interstate system, as well as the potential for attractively landscaped settings. Uses in the office research parks could include national or regional offices in addition to research facilities such as A.C.T. and Westinghouse. Manufacturing Manufacturing uses may locate in the Southeast Industrial Park on U.S. 6, and on the east side of U.S. 218 southeast of the airport. Access to the transportation network is adequate in these areas; however, the improvement of Scott Boulevard will increase the attractiveness of the Southeast Industrial Park for potential industries. The new sanitary sewage treatment plant will also serve to increase the potential for manufacturing expansion. Performance standards are included in various State and City or- dinances to regulate industrial pollution and to minimize impact on adjoining non -industrial uses. Additional areas for industrial development may be needed as new industries locate in Iowa City. The following areas are recom- mended as suitable for industrial or light industrial land use at such a time as more land is needed for these uses: 1. Land in close proximity to I-80 in northeast Iowa City (light industrial use). 2. Expansion of the Southeast Industrial Park eastward south of the railroad (light or heavy industrial uses). 3. Land in proximity to the Iowa City Airport (light or heavy industrial uses). 63 141CROMMED BY DORM MICRI ILA9 MILROFILMED BY JORM MICROLAB CEDAR RAPIDS AND DES MUIIIL�, IUvil1 Extraction Two extraction sites are shown, the City Landfill west of the city limits and a sand and gravel extraction operation on South Gilbert Street. When operations have been completed at these sites, they may provide additional parkland for the community, or other similar use. TRAFFIC WAYS An important feature of the Land Use Map is the location of major streets. New streets shown as heavy lines on the map will be developed to primary or secondary arterial street standards. The lightest lines indicate collector and local streets. The arterial street system can be divided into two parts: the peripheral arterial system and the central arterial system. Features of the peripheral system include a western bypass (re- located U.S. 218) a new eastern bypass, a new southern bypass, and I-80 on the north. The western bypass is located some distance to the west of the 20- year growth line in order to preserve the development potential of the Willow Creek watershed. i The development of an eastern bypass in addition to Scott Boulevard is important as a means of improving access to the Southeast In- dustrial Park area, and as a means of minimizing the intrusion of truck traffic in residential areas. The eastern bypass is located one mile east of Scott Boulevard on what is now a county road. Curving to the west, this bypass intersects U.S. 6 at the U.S. 6/Scott Boulevard intersection. The bypass continues southwest and joins the proposed southern bypass about one mile east of the Iowa River. The southern bypass will extend east from the intersection of relocated U.S. 218 and existing U.S. 218 South approximately one mile south of the existing City limits. Construction of a new Iowa River bridge will be necessary. This completed bypass system will provide alternative routes to through traffic, considerably re- ducing traffic congestion and disruption on City streets. The purpose of the central arterial system is to provide efficient traffic flow through various parts of the city with emphasis on the University, the hospitals, and the downtown areas.

The principal elements which have determined this sequencing pattern include the phased extension of arterial streets, sanitary sewers, and water mains. Existing capacities of the above-mentioned systems also exert considerable influence on the sequencing of development. The ability to provide adequate levels of police and fire protection, and transit service are also instrumental in the development sequencing pattern. Specific discussion of these factors is set forth below: EXISTING SEWER CAPACITY Existing sewer capacity is discussed in the Report on Utilities and the Locational Factors Report, and is under study by the Department of Public Works. Within the established portion of the city, there is sewer capacity to accommodate infill development, including modest increases in residential density, for approximately 5,000 persons. Major undeveloped areas which can be served by existing sewer lines are: a portion of the Willow Creek Watershed; the area south of U.S. 6, east of Gilbert Street and west of Sycamore Street; and the area in the north branch of the Ralston Creek watershed north of Rochester Avenue and west of Scott Boulevard. Once the new river corridor sewer improvement is completed, the area south of Interstate 80 between Dubuque and Dodge Streets will be served as well as the peninsula area which is bounded by Dubuque Street on the east, by the Iowa River on the south and west, and Interstate 80 on the north. The provision of sewer service to the above-mentioned areas is limited by the capacity of downstream trunk sewers and the capacity of the City's sewage treatment plant. COST EFFECTIVE SEWER SERVICE The development of areas contiguous to existing or proposed major sewers with adequate system capacity is generally the most eco- nomical form of development. K• 'tJ IdICROf ILIdf.O BY ' JORM MICRd•LAB 67 W OIUROFILMED BY JORM MICROLAB • CEDAR RAPIDS AND DLS MUINLS, :NA It is therefore recommended that areas of existing sewer capacities and areas which are to be provided with adequate sewer capacity in 1978-1979 be initially developed. This will include the following areas: a. Infill development b. Eastern portion of the Willow Creek watershed area C. Area south of U.S. 6 between South Gilbert and Sycamore Streets d. Peninsula area west of Dubuque Street e. Area between North Dubuque Street and North Dodge Street south of I-80. Upon completion of the proposed new wastewater treatment plant facility on South Gilbert Street, areas which could be provided with relatively economical sewer service include the following: a. Area south of U.S. 6 and east of South Gilbert Street, and b. Undeveloped area in eastern Iowa City known as Village Green Rehabilitation and increasing the capacity of existing sewers within the community and in the area draining into the north branch of Ralston Creek will allow for the following developments: a. Infill development in the established portions of Iowa City, and b. The north branch of Ralston Creek west of Scott Boulevard Once a final pattern of priorities has been established, new de- velopment should occur contiguous to existing developed areas. The undeveloped area located in the western part of the Willow Creek watershed, (generally west of Mormon Trek Boulevard) will not be able to be provided with adequate sanitary sewer service until substantial sewage system improvements are made. Also, the area in extreme northwestern Iowa City which is within the Clear Creek watershed can not be economically provided with sanitary sewer service. PROJECTED TRAFFICWAYS PROJECTS Several major trafficway projects can be expected to be implemented within the next twenty (20) years. These projects are as follows: a. Paving of Mormon Trek Boulevard from Benton Street south to the city limits. b. Relocation and widening of South Gilbert Street south of U.S. 6. c Construction of Foster Road between North Dubuque Street and North Dodge Street. @ICROf ILMLO BY , JORM mtCROLAS ,DAK R,: i[.

Extension of Lakeside Drive west to South Gilbert Street. v Other trafficway projects which may be implemented within the next twenty (20) years are categorized as follows: 1. Widening of North Dodge Street from Governor Street to the Interstate 80 interchange. 2. Construction of a southern bypass route from South Gilbert Street to the U.S. 6/Scott Boulevard intersection. 3. Construction of an eastern bypass between U.S. 6 and the Local Road interchange with Interstate 80. If Freeway 518 is constructed, it may be necessary to implement the following traffic projects: 1. Widening Melrose Avenue between Freeway 518 and West High School. 2. Construction of Melrose Avenue around University Heights, or widening of Melrose Avenue along the southern border of the University of Iowa Medical and Sports Complex, construction of a diagonal from Melrose Avenue to the Burlington Street Bridge. Continued discussion with the University of Iowa may result in alternative solutions (such as a West Campus bypass) to traffic routing in the area of the Health and Sports Complex. The projects which will have the most significant impact upon regulating growth are those that will provide access to areas currently without paved roads. The combined effect of providing access coupled with extended sewer service will be a strong impetus for development. PHASING PUBLIC IMPROVEMENTS The ability of the City to provide municipal services and facil- ities, particularly sanitary sewer service and major trafficways, has a direct impact on the sequence in which areas of the community develop. The availability of public facilities does not greatly affect the community's overall growth rate. However, because financial limitations make it necessary to schedule the construc- tion of new public improvements over a number of years, the time at which specific areas can be provided services varies. In the analysis of alternative waste water treatment plant sites, emphasis was placed upon incremental expansion of capacity within 69 MICROFILM BY JORM MICR4�LAB l.i.d/d:. 'r.',.., L'i.' '10::1'. r4iLROFIL:4ED BY JORM MICROLAB CEDAR RAPIDS AND OLS MU1NL), 10eJA and around the perimeter of the existing developed area, rather than redirecting growth to a particular sector. Contiguous growth which utilizes capacity of existing facilities is more economical than building all new facilities for new development. However, the location for the new waste water treatment plant does make it more economical to develop the area close by, than to extend new trunk sewers to other undeveloped areas around the perimeter of the city. Major trafficways provide a development framework. An orderly functional classification system in both existing and new areas ensures the availability of rights-of-way in appropriate locations to serve the anticipated volumes of traffic generated within each area of the city. Because the transportation network not only provides access to adjacent property, but also serves to carry traffic from location to location, system continuity is important. It is frequently necessary to extend major trafficways to logical connections with the existing system, even though the development of adjacent property is not imminent. The schedule below contains the recommended sequence for the provision of public improvements. The schedule contains four distinct phases for public improvements. The first phase is expected to be a seven year increment, while the other three phases are expected to be five year increments, ending at the year 2000. i 1. Phase I Improvements Sewage projects: a. Construct the river corridor trunk sewer. b. Construct the new wastewater treatment plant. � I Trafficways projects: Wel a. Relocate Gilbert Street south of U.S. 6. b.

OTHER FACTORS AFFECTING DEVELOPMENT SEQUENCING PATTERN The City's ability to provide adequate levels of police and fire protection as well as mass transit service are other factors which must be taken into consideration in development sequencing. 141CROFILMEO BY JORM MICR6LAB CCDAF: kllr ;;r dCl id0;GFS r.� a go v M11CROFILMED BY JORM MICROLAB IMPLEMENTATION INTRODUCTION CEDAR RAPIDS AND ULS MOINL), !UwA The implementation of this Comprehensive Plan will involve the use of a complex mix of implementation tools. A municipal government, in carrying out policies set forth in a Comprehensive Plan, does so primarily by enacting regulations or by allocating resources. Zoning ordinances and subdivision regulations are the primary land use regulatory devices. The Capital Improvements Program and capital budget are principal tools used to manage the expenditure of funds for purposes established in the Comprehensive Plan. Annexation as a policy tool, has direct impact on the spatial pattern of development planned for in the Comprehensive Plan. Cooperative agreements with other public bodies provide additional management capability in carrying out community development pol- icies. ►,��i� • • 0`0 - woo A revised ordinance will be one of the major means of implementing the Comprehensive Plan. In this manner, the City, pursuant to Iowa Code Chapter 414, will adopt the regulations and restrictions which will, in large measure, implement the ranges of population density and locations for various types of land uses which are shown on the Comprehensive Plan Map. The specific source of the City's power to so regulate is found primarily in Iowa Code Sections 414.1 and 414.2. Under Section 414.1, the City, for the purpose of promoting the health, safety, morals or the general welfare of the community, is empowered to regulate and restrict the height, number of stories, and size of buildings and other structures. Also the City may regulate the percentage of lot that may be occupied, the size of yards, courts, and other open spaces, the density of population and the location and use of buildings, structures, and land for trade, industry, residence, or other purposes. Section 414.2 goes on to provide that for any or all of said purposes the City Council may divide the City into districts of such number, shape, and area as may be deemed best suited to carry out the purpose of Chapter 414. Within such districts the City may also regulate and restrict the erec- tion, construction, reconstruction, alteration, repair or use of Id ICROFILMEm BY ' JORM MICRd)LA© li:JAl' idi,'.':.., L1, '40;4ES 73 FM 1-11lRUFILHED BY JORM MICROLAB CEDAR RAPIDS AND DES MUIi1L�, IUWA buildings, structures, or land. A limitation is that all such regulations and restrictions must be uniform for each class or kind of buildings throughout each district, but the regulations in one district may differ from those in other districts. Therefore, Iowa Code Chapter 414 delegates specific power to the City of Iowa City to enact the zoning regulations which will implement portions of this Comprehensive Plan. Additionally, Iowa Code Section 414.3 requires such zoning regu- lations to be made in accordance with a Comprehensive Plan. There- fore, the Comprehensive Plan and the revised Zoning Ordinance are complementary. The zoning regulations, in large measure, implement the Plan, while the Plan serves as a basis of the zoning regula- tions. Thus, the Comprehensive Plan embodies policy determinations and guiding principles while the revised Zoning Ordinance will provide the detailed means of giving effect to those principles. The City has given careful consideration to the community's land use problems and, after careful study of its present and foresee- able future needs, has adopted this Comprehensive Plan. The amended Zoning Ordinance to follow will divide the city into dis- tricts and regulate land uses within those districts in accordance with this Comprehensive Plan pursuant to the Iowa Code. The over- riding consideration upon which designation of zones in the revised Zoning Ordinance will be based is the compatibility of the zoning district regulations (in terms of character and uses permitted) to the designation indicated by the Comprehensive Plan Land Use Map. Table I indicates the type of compatible zoning designations that are intended for the various Comprehensive Plan Land Use Map desig- nations. An examination of Table I reveals that within several of the Comprehensive Plan Land Use Map designations, more than one zoning district designation may be appropriate. Also, there is overlap so that a zoning district which is compatible within the 8- 16 DU/A designation, for example, is also compatible within the 16- 24 DU/A designation. In drawing actual zoning 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 -tens goals for development within the City, the zoning 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.

SUBDIVISION REGULATIONS /Aff • =- IIullll The City of Iowa City's review and approval power over subdivision plats gives the City another means of implementing its Comprehen- sive Plan. Iowa Code Section 409.14 provides that no county re- corder shall file or record any plat purporting to lay out or subdivide any tract of land into lots and blocks within any city having a population by the latest federal census of 25,000 or over, or within two miles of the limits of such city, unless such plat has been first filed with and approved by the council of such city as provided in Section 409.7, after review and recommendation by the city planning commission in cities where such commission exists. The fourth paragraph of Section 409.14 contains language which clearly authorizes review of said plats for conformance with the city's Comprehensive Plan where such exists. J "Said plats shall be examined by such city council and city plan commission where such exists, with a view to ascertaining whether the same conform to the statutes relating to plats within the city and within the limits prescribed by'this section, and whether streets, alleys, boulevardsarks and ppubl�ic1p aces sha 1 conform to the 9 eneral lomat of the city a�ondone to an or era iv development t ereof, aU not streets or alleys airea,ay escao n sneu or ocnerwise m4t:11 - witth the carrying out of the comprehensive city _plan, in case such as has been adopted by such city.

Finally, the City Council may require as a condition of approval compliance with reasonable requirements in regard to installation of public utilities or other improvements Council deems requisite for the protection of the public interest. Therefore, because the City Council deems it requisite for the pro- tection of the public interest that an amount of land for parks based on the standards specified in this Comprehensive Plan be C provided for the residents within a subdivision, the City Council has expressed interest in the adoption of a Minimum Open Space requirement. Such a requirement, as a condition to plat approval, would require a developer to provide a minimum amount of common open space per dwelling unit, in order to reserve land for parks to serve residents of the developed subdivision. c. The Minimum Open Space requirement, as outlined by City Council, would allow the developer two alternative methods of providing open space: (1) the developer may set aside within the subdivision, open space to be maintained privately (e.g., through a homeowners' association); (2) if the City wishes to incorporate the developer's open space into a neighborhood park, the developer may dedicate the open space to the City. In addition, it may be possible for the developer to pay to the City fees in lieu of open space or park- land. Certain restrictions on the quality and location of the land which could be provided as open space would be specified in the ordinance to insure adequate usable space for active and passive recreation. However, portions of steep slope areas and portions of storm water detention sites would possibly be accepted as part of the required open space. A minimum open space requirement would provide a mechanism which would allow the developer to achieve the same number of lots or dwelling units within the subdivision as would have been attainable without the provision of open space. Consequently, the open space requirement would not increase, and may in fact decrease, costs for the developer or home buyer. Approval of any subdivision plat by the Planning and Zoning Com- mission and the City Council would be contingent upon conformity of �, .. AICRDf ILIdCD BY JORM MICR46LAB .rt.'. '101,. S IdIuROFILK D BY JORM MICROLAB CEDAR RAPIDS AND ULS MUINE�, iU'rll: n the subdivision with the Comprehensive Plan and the Minimum Open ^ Space Requirement. The Minimum Open Space Requirement has a legal status similar to mandatory park dedication. The City Attorney's memorandum of March 5, 1974, to the Mayor and City Council regarding mandatory dedi- cation concluded: "The status of mandatory dedications in Iowa is uncertain as the memorandum indicates (reference is to a research memoran- dum of February 8, 1974, by Assistant City Attorney Dick Braun). Chapter 409 of the Code of Iowa does not specifically grant municipal corporations this power. However, it is our opinion that the City does have the power to require mandatory dedication or fees -in -lieu of dedication if the following standards are adhered to as set forth in the memorandum: 1. The park required must be included in our comprehensive or general plan. 2. The subdivision exaction must be considered reasonable, with regard to the subdivision in question. 3. The requirements must be attributable to the specific needs of the subdivision in question. 4. The advantage gained from the requirement must be used to the direct benefit of the people in that subdivision. You should be aware that enactment of mandatory park land dedications would probably result in litigation in the courts over the issue because of the cost of compliance with such requirements to subdividers along with the uncertainty of the legal status of the requirement." PROGRAMMING CAPITAL EXPENDITURES tm-*, t The Comprehensive Plan establishes a pattern of orderly growth for the community. Central to this orderly growth is the framework of public facilities around which the community develops. The Capital Improvements Program and the capital budget are the principal management tools available to ensure that the needed public facil- ities can be provided at the time and in the locations necessary to ensure efficient and orderly development. The Capital Improvements Program links the development policies established in the Compre- hensive Plan to the future expenditure of funds and provision of capital improvements. 11 141CROf ILMED BY JORM MICR4�LAB 6'i'IIAI'.

IUAA The Comprehensive Plan includes the needs for public facilities which were identified during the planning process. The Plan also establishes policies regarding the provision of public facilities, even where the specific facilities have not yet been identified. Need for additional capital expenditures will become app arent, from time to time, as community growth occurs. The Capital Improvements Program serves two primary municipal management functions. First, the City systematically reviews all capital projects for consistency with the adopted goals, objec- tives, and policies established in the Comprehensive Plan. Spe- cific positive and negative impacts of capital projects can be considered in light of existing municipal policies. Second, the Capital Improvements Program serves as a strong financial manage- ment 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 Capital Improvements Program (CIP) is a mid-range (5-10 year) planning and management tool. It should include all capital facil- ities requirements expected to be needed within the established time period. Capital improvements programs are generally prepared jointly by the planning staff and the finance staff, with assist- ance from the departments with capital facilities needs. The CIP process normally prioritizes all foreseeable capital needs. This priority ranking is followed by an assessment of financial cap- ability, debt limitations, debt service ability, and the identi- fication of sources of funding. Based on this information, capital expenditures are programmed to occur over the designated five to ten year period. The highest priority items are included in the program for the first year, consistent with financial limitations imposed by State law or the fiscal policy. The first year of the Capital Improvements Program becomes, after the City Council deliberation, the capital budget for the next fiscal year. Because capital improvements needs cannot always be foreseen, and becausespriorities s should change, athe ken capital improvements programming p annually. Adjustments to the schedule must be made according to changed priorities or circumstances. The use of a Capital Im- provements Program does provide the essential link between the goals and objectives set forth in the Comprehensive Plan and the financial management of the provision of needed public facilities.

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. ANNEXATION At the present time, no official City policy regarding annexation exists. However, the Utilities, Landforms, Land Use Concepts and LocationalFactors Reports found in�ndix A all suggest an approach to annexation based on protecting watersheds. This ap- proach must be taken into consideration along with the other fac- tors discussed in this section in making any annexation decision. The following factors should be considered by the City Council prior to making a specific decision on whether to annex a par- ticular area: 1. Whether the given annexation will bring within the city limits, a portion of a watershed over which the City should exert control. The Landforms Guide in Appendix A identifies watersheds which can a use as planning units. This pub- lication concludes that flooding and sewer service problems can be minimized by a process which utilizes the character- istics of watersheds as planning guidelines. 2. Whether increased land use controls (above and beyond the extraterritorial subdivision control of the City) are neces- sary to control development in an area. If so, annexation would be indicated. In some instances, the City may wish to exert zoning control along existing and potential highway corridors or interchanges to guard against inappropriate development and to protect traffic carrying capacity.

Whether the annexation is fiscally sound for the City of Iowa City. The financial implications of annexation are complex. The City is required to expend additional money to serve the annexed areas. Annexation will spread the payment for facil- ities and services over a broader area, and thus will tend to reduce the amount levied per $1,000 of assessed value of taxable property. There is the complicating factor in that the Iowa Code Section 24.36 limits the aggregate increase of the General Fund levy, as well as several other specific levies, to 7%, or in certain circumstances, to 9%. Yet, limited facilities and services will be serving a broader area. Therefore, annexation will not serve to improve the fiscal posture of the City. The City assessment may be spread somewhat; however, the increase in the General Fund levy is still limited by law. If the percentage limit is removed, the ultimate fiscal que- stion is whether the increased tax base derived from annex- ation is sufficient in view of the cost of extending sub- stantial municipal services not previously provided in the annexed area. It is beyond the scope of this Comprehensive Plan to answer this question for annexations. Rather, this consideration must be made on a case by case basis in an- alyzing proposed annexations. Whether the City has the capability of extending substantial municipal services and benefits not formerly enjoyed by the residents of the proposed annexation area. Proof of this capability will negate any claim that the City annexed the area solely to increase its tax revenue. The City has the burden of proof and whether there will be a substantial in- crease in services becomes a question of fact for the courts which will consider the level of services before and after annexation. However, it is not necessary that all services be extended before the City is entitled to annex adjoining property. lam �a COOPERATIVE To effectively implement this Comprehensive Plan, the City of Iowa City needs to work closely with other government entities. MICROFILMED DY DORM MICR LA6 0 0 W r41LkOFILMEU BY JORM MICROLAB n CEDAR RAPIDS AND ULS MOINES, IOviA Cooperation and coordination between these various governmental units will be necessary to ensure implementation of Iowa City's Comprehensive Plan in regard to transportation, community facil- ities, and development outside the city limits. Agreements need to be explored in the following areas: 1. An agreement to constitute a basis for actions of the Iowa City School Board and the City of Iowa City in executing a plan for cooperation, joint planning, and respective use of school buildings, neighborhood playgrounds, playfields, parks and school/park sites in the City of Iowa City. In such an agreement, the school board and the City would mutually agree that, in acquisition and planning of a school, recreation or park area, whether acquired jointly or independently, each will inform the other as far in advance as is practicable, of its plan for acquisition and development of sites which may become mutual resources. It would be understood that neither governmental unit would be obligated to conform to the desires of the other. However, it is recognized that such cooperation iv in acquisition, planning, and construction will create certain economic advantages. 2. An agreement between the City of,Iowa City and Johnson County relative to development standards and land use in the area outside the city limits but within the City's extraterritorial jurisdiction. 3. An agreement between the City and the University of Iowa regarding permitted land uses along the interface of property under City and University jurisdiction, as well as the use of utility services and trafficways through City and University property. In this manner, it is hoped that an ongoing effort by the various governmental entities will serve to increase the services provided by all, heighten efficiency of operations of each, and fulfill specific obligations to the citizens of the community with the lowest cost to the taxpayer.

The Comprehensive Plan will be most useful in future years if it is utilized as a valid working document and as a guide for decision-making. The n Plan has been prepared based on the gathering and analysis of factual information, commentary from thousands of citizens, and on endless hours of work contributed by local governmental officials and City staff personnel. In order to protect this substantial investment of time and effort, it is essential that future Planning and Zoning Commissions, and City Councils periodically update the Plan in order to adequately reflect changes occurring in the community. Although the Plan generally addresses itself within a twenty (20) year time frame, a thorough review of the Plan should occur every three to five years. j0 It is also recommended that when Council policies deviate from the provisions of the adopted Plan, that the Plan be amended in order to accurately reflect current Council policies and priorities. i i J 4 V I4ICR01'IL41[11 BY ' JORM MICROLAB CLOAK [!A;' I)' • .:LS 1101NCS 87 m MICROFILMED BY JDRM MICROLAB CEDAR RAPIDS AND DES MOINES, IOWA K� -tf 141CROFILMEO BY JORM MICR+LAB UOAR ii.0 ;:n • :xs ;aor,rs r MILROFILMED BY JORM MICROLAB GLOSSARY CEDAR RAPIDS AND ULS ;IUINL), 10wi A brief definition and explanation is given of some of the land use and other terms used in the Comprehensive Plan Map and the accompanying text. Agriculture: A land use restricted to typical farming operations such as cropland, pasture, feedlots, and farm dwellings. Residential de- velopment at a density of less than one dwelling unit per acre may be permitted on land not suitable for agriculture. Alternative Mode of Transportation: Any means of transportation other than automobiles. Generally refers to mass transit, bicycling and walking. Buffer: Trees, shrubs, landscaping and appropriate fences which serve to screen objectionable views, control environmental factors and protect less intense land uses from glare, noise, dust, and excessive heat. Ca ital Improvement Program: A five year plan (which is updated every year for providing capital improvements such as sewers, roads, and parks, which are closely coordinated with the Comprehensive Plan to permit orderly development and redevelopment. Central Business District (CBD): The high density, compact, pedestrian - oriented shopping, office and entertainment area in central Iowa City. Cluster Development: An example of a planned unit development in which dwelling units are built closer together than in a traditional sub- division. While the overall housing density is maintained, the costs of streets and utilities is reduced and, through clustering, common open space can be provided. Collector Street: Serves the dual function of circulation and access, with access taking precedence. Collector streets are designed to carry moderate volumes of traffic (1,000 to 5,000 vehicles/day) relatively short distances to and from arterial streets. Comnunit Park Sites: Park sites intended for use by residents of a arge area of the city. Core Areas: Those locations where employment and/or shopping oppor- tunities are concentrated. Comprehensive Plan: A document describing Iowa City's goals, objectives and policies, and their implementation, for use as a guide in public and private decision-making.

Fragile Environmental Features: Areas of scarce vegetation types and habitats, unusual topography, scenic views, or important natural re- sources. General Cgmmercial: Uses including retail stores, eating and drinking establishments, services (e.g., barbershops) and offices. In some areas, use may be restricted to specific categories such as neighborhood commercial. Greenbelts or Greenways: Corridors of open space which include bikeways j and walkways, providing access to public facilities. j Gross Densit The number of dwelling units per unit area of land (usually expressed as dwelling units per acre), which includes both privately and publicly owned land. j Headwaters: The area where the waters forming a creek or river orig- inate. Highway Commce ercial: Businesses primarily serving transients such as motels, servistations, restaurants. Land Consum tive Commercial: A designation for wholesale and retail usinesses which require a large amount of land. Included are auto dealerships, wholesale operations, construction yards, building supply establishments and light industrial uses. Lateral Sewers: Sewers serving individual building connections and dis- charging wastes into trunk sewers. Lift Stations: Pumping stations which pump waste water to a higher elevation so that it can then be carried in a sewer by gravity flow. LocalStreet: Serves the function of circulation for access to prop- erty. Local streets are designed to carry only small volumes of traffic (up to 1000 vehicles/day) and to discourage high-speed and high-volume use.

Neighborhood Park Sites: Potential park sites intended primarily for use by the surrounding neighborhood. Office Zone: Professional offices and related retail firms such as pharmacies are located in this zone. Office Research Park: A land use including service oriented industries which serve an area larger than Iowa City, such as data processing. Offices may also appear in this land use. One Dwelling Unit Per Acre (1 DU/A): Areas which cannot be efficiently served by sanitary sewers or have relatively steep or broken topography yet are suitable for residential use, are designated for a density of one dwelling unit per acre and less. Septic tanks can be used in these areas. Out Fall Sewers (Interceptor Sewers): Convey waste from trunk sewers to The waste water treatment plant.

The standards and calculations included in this appendix have not been approved by the Planning and Zoning Commission separate from their use in the planning process. The Planning and Zoning Commission has reviewed and trans- mitted Appendix B to the City Council for consideration as part of the Comprehensive Plan Text. NEIGHBORHOOD COMMERCIAL CENTERS The location and size of the proposed neighborhood commercial centers shown on the Comprehensive Plan Land Use Map reflect the economic goals and objectives expressed in the Plan. It is an economic objective to provide for neighborhood commercial centers designed to blend in with, and serve, residential neighborhoods. Thus it is recommended that use of Planned Unit Development be encouraged to maximize the ability to effectively blend neighborhood commercial activity into residential neighborhoods. It is also recommended that there be no zoning or rezoning for addi- tional large commercial areas that would detract from existing com- mercial areas. The neighborhood commercial centers shown on the Plan Map reflect a balanced approach of providing for neighborhood com- mercial centers in a trade area large enough to support them, while recommending that their size be such that they will not detract from existing commercial areas. Assumptions and Criteria for Development 1. The major function of a neighborhood commercial center is the sale of convenience goods and personal services. 2. Neighborhood commercial centers were located where possible near the intersection of secondary arterials or collector streets. 3. The minimum population to support a neighborhood commercial center was deemed to be 4,000. However, service areas delineated range from approximately 7,500 to 14,000 in potential population to ensure adequate support. 4. Total site area for neighborhood commercial centers should be no larger than 7 acres. 5. In order to achieve the desired scale for neighborhood commercial centers, a standard of one (1) acre per 2,000 population was utilized to arrive at a recommended site area for centers shown on the Plan Map. This standard reflects the policy decisions that the type of neighborhood commercial centers desired would be no greater than 7 acres in size and have a limited number of stores designed to serve residents of the area. i. Four (4) new neighborhood centers were located on the Land Use Plan Map based upon nearness to secondary arterial or collector street MICROFILM) BY DORM MICR#LAB J'i '101'7..: U1 F LEGI 0 existing or proF ■ new neighborha trade areas for ,\\\: neighborhood p 111t,ROFILMEU BY JORM 141CROLAB CEDAR RAPIDS AND ULS MUIML�,, iUr4A TRADE AREAS FOR NEW NEIGHBORHOOD COMMERCIAL CENTERS APPENDIX B, MAP 1 H MICROFILMED BY JORM MICROLAB CEDAR RAPIDS AND DES MO1NL5, IOWA intersections, central location to an adequate service area pop- ulation, and proximity to higher density residential land 7.

According to the recommended standards in this report, for the approximately 95,000 potential pop- ulation depicted on the Land Use Plan Map, two 100 acre (minimum) city- wide parks should be provided. Hickory Hill Park (approximately 17.5 acres) and the adjoining 80 acres of undeveloped City cemetery property serves as one community/city-wide park. The 80 acres will be gradually reduced as more cemetery space is needed. However, much of this land will be in park use for the next 20 years. A 20 acre addition to Hickory Hill Park has been proposed. City Park (105.2 acres) is the second community/city-wide park which serves Iowa City. The Community Facilities Report recommends provision of ten acres of community and city-wide Parr k land per 1,000 population. Currently there exists ten acres of park land per 1,000 population for all types of park land, approximately eight acres per 1,000 population is provided for city/community-wide park land. Park and recreation area provided by the University of Iowa is not included in the city park totals, but cer- tainly contributes valuable recreation opportunity. Private recreation areas, such as golf courses, fairgrounds, and similar areas, were also not included. In addition, Coralville Reservoir, Lake Macbride State Park, and Kent Park provide considerable recreation opportunities. For these reasons, it is recommended that seven acres (as opposed to ten acres) per 1,000 population of community and city-wide park be allocated as the city develops. For the potential population of 95,000, a total of approximately 665 acres of community and city-wide parks are needed, which is an increase of approximately 260 acres. This acreage will be provided primarily in the form of a new riverfront park (approximately 200 acres) shown on both sides of the Iowa River southeast of the Airport. (Mesquakie Park adjoins this proposed riverfront park and is 64 acres in size.) Another park, approximately 40 acres in size, is shown along the Iowa River opposite the old Coralville Power Dam (11 of these acres contribute to the neighborhood park land allocation). These two riverfront parks are in accordance with the recommendations of the Iowa River Corridor Study completed by Stanley Consultants in 1977. The proposed 20 acre addition to Hickory Hill Park will also contribute to the necessary additional community/city-wide park land. Five acres per 1,000 population of neighborhood and mini -park land was recommended in the Community Facilities Report and subsequently adopted by the CPCC. Currently, there are approximately two acres per 1,000 population of neighborhood and mini -parks. School playgrounds were not included in this total although these areas frequently serve as neigh- borhood parks. The following assumptions and locational criteria were used in the distribution of neighborhood park land: 1. Neighborhood parks are allocated at five acres of neighborhood park per 1,000 population. 2. Neighborhood parks should be a minimum of five acres in size where possible. 102 MICROFILM BY JORM MICR6LAEI n MILROFILHED BY JORM MICROLAB CEDAR RAPIDS AND DES MOINL�, IUwA 3. Residents in areas where the density is greater than two dwelling units per acre should be within one-half mile of a park where possible. 4. In areas shown on the Land Use Plan Map as developing at two dwelling units per acre or less, no neighborhood parks will be allocated as adequate open space exists for residents of these areas. 5. Generally, the existing population of Iowa City is adequately served by existing city parks and other usable open space. 6. Where redevelopment at a higher residential density than currently exists in an area is indicated by the Land use Plan Map, the higher population density was considered in allocating new neighborhood parks. 7. In fringe areas or new neighborhoods not totally developed,po- tential total population (existing and future) was considered in neighborhood park allocation. 8. Parks are located (where possible) in areas where attractive physical features exist such as rivers, streams or lakes, scenic views, woodlands, or rock formations. g. A minimum of ten acres of park land (neighborhood or community/city- wide) should be located adjacent to each potential school site. 10. Greenways along rivers and streams were not included in allocated park land, unless they were within existing or proposed parks. 11. Neighborhoods are defined as units of potential population of approximately 5,000-7,000 persons, divided along barriers such as major trafficways, rivers, major change in land use, and similar features. Following are the allocations of neighborhood parks within individual neighborhoods. The existing neighborhoods are not included where additional park land is not desire adequate park land exists, wd (by here residents of the neighborhood) or where undeveloped land for potential park sites does not exist. Community park land allocations are also provided. As some of the neighborhoods are partially community parks, the as these residents are already served by existing i additional park land needed for community/city-wide parks is less than the 452 acres calculated on page log. Acreage which has been designated for potential school sites has not been included in park land calcu- lations. r , tdlC Rnf IL141D BY JORM MICR6LAB LI.JAi; k,': ': ,L '401'1: 7 103 MICROFILMED BY JORM MICROLAB CEDAR RAPIDS AND UES MOINLS, IOWA NEIGHBORHOOD Total Residential Acres = 723 Density Potential** Persons Potential** in DU/A* Acres DU's Per DU Population 0.5 723 362 2.8 1013 Total Potential Population = 1013 Park Allocation i Neighborhood Park - none (based on assumption N4) Community Park - 1013 X 7/1000 = 7 acres *Dwelling Units per Acre **Includes existing and future '1 E NEIGHBORHOOD II i Total Residential Acres = 377 I i jDensity Potential Persons Potential in DU/A Acres DU's Per DU Population 4 333 1332 2.8 3730 10 18 180 2.8 504 20 26 520 2.0 1040 Total Potential Population = 5274 104 Park Allocation Neighborhood Park = 5274 X 5/1000 = 26 acres Community Park = 5274 X 7/1000 = 37 acres MICROFILMED By JORM MICR6LAS C I.GN;

Dubuque Street, south of Rapid Creek, and west of the Office Research Park on Highway 1. Land Use Existing land use includes very low density residential, woodlands, and agriculture. Proposed use is very low density residential (less than 1 dwelling unit per acre) because of the broken topography, woodlands, and lack of sanitary sewer service. Population Approximately 35 residential dwellings are in this neighborhood, most are located along Linder Road. Additional land is available for approx- imately 325 new units, with a corresponding population of about 915 additional persons. Utilities This area cannot be economically served by sanitary sewers. Therefore, residents will require septic tanks and individual lots will be sized according to soil sample results. Trafficways No additional arterials are proposed for this neighborhood. Dubuque Street and Prairie du Chien Road are the primary trafficways. Community Facilities There are no existing community facilities within this neighborhood. Neighborhood parks are not necessary in areas of less than two dwelling units per acre, therefore none are provided. A greenway will be main- tained along Rapid Creek and along Interstate 80. NEIGHBORHOOD II This area in the northwest of Iowa City is bounded by the Iowa River to. the west and south, and by North Dubuque Street on the east, and I-80 to the north.

A number of single- family dwellings are located along the river on Taft Speedway, Foster Road and Knollwood Drive. The Elks Club, with recreational facilities and a golf course, covers approximately 70 acres in the center of the peninsula. Much of the land adjacent to the river is in the flood plain. Proposed land use for the peninsula is largely low density residential (2-8 dwelling units per acre) with some higher density residential (8-16 dwelling units per acre and 16-24 dwelling units per acre) in the area between Foster Road and I-80. Population There are currently approximately 210 dwelling units in the peninsula area. The Plan projects an additional 1,740 dwelling units for an increased population of about 5,000 residents. Utilities A new north -south trunk sewer on the east side of the Iowa River, ex- tending to Foster Road, will be installed in 1978. Upon completion of this sewer the entire peninsula can be serviced. Water is available to part of this area as are other utilities. Transportation Foster Road will be the main collector street serving the pensinsula and linking with North Dubuque Street. Community Facilities J A five acre neighborhood park is proposed in the northern part of the peninsula to serve the higher density residential area. A 20 acre park/school site will be reserved in a location central to the peninsula residents. A 40 acre riverfront park located near the Coralville Power Dam will serve not only the residents of the peninsula (11 acres is - intended for this use) but also as a community park for all Iowa City residents and canoeists, bicyclists, hikers and fishermen using the river and river side trail. A river corridor buffer at least 100 feet wide, with a bikeway/walkway trail is planned along the river as part of a continuous trail system. Terrill Mill Park, a community park, about 18 acres in size, is located between North Dubuque Street and the Iowa River in the southeast corner of the peninsula. No neighborhood com- mercial center is planned in this area. NEIGHBORHOOD III This neighborhood is located south of Interstate 80, north of Brown, and between N. Dodge and N. Dubuque Street.

Land Use Existing land use includes Hickory Hill Park, two cemeteries, Regina High School, and single-family residential generally south and east of the park. Most of the area is in agricultural use or vacant. The north branch of Ralston Creek flows across the lower portion of this neigh- borhood. Proposed residential land use includes: moderately high density residential (16-24 dwelling units per acre) along N. Dodge and north of the HyVee on Rochester; moderate density residential (8-16 dwelling units per acre) on either side of St. Joseph's Cemetery (ad- jacent to the moderately high density residential area, east of the Office Research Park on Old Dubuque Road, and along Rochester Avenue; and low density residential (28 dwelling units per acre) on most of the remaining land area. A neighborhood commercial/moderately high density residential mix will be permitted on N. Dodge between N. Summit Street and St. Joseph's Cemetery (as indicated on the Land Use Plan Map). Population This neighborhood has a potential population of approximately 9,600 persons. Utilities This neighborhood -can be served by the existing sanitary sewage treat- ment facility. Where trunks do not exist, they will be extended by developers. Trafficways The major new transportation facility will be the extension of First Avenue north to Old Dubuque Road. This portion of First Avenue will serve as an arterial. Improvements will also occur on Scott Boulevard, Old Dubuque Road, and N. Dodge.

NEIGHBORHOOD V This area lies west of Mormon Trek Boulevard and south of Melrose Ave- nue. It extends south to the present city limits. Land Use Some higher density residential development has already occurred in this area. The Mark IV subsidized housing complex is located adjacent to Mormon Trek Boulevard, and a townhouse development has been recently ? constructed just south of Melrose Avenue. The 80 -acre West High School site extends south from Melrose Avenue, and a church is located at the intersection of Melrose Avenue and Mormon Trek Boulevard. The rest of i the area is presently in agricultural use. An extension of higher density (8-16 dwelling units per acre) use is recommended along Mormon Trek Boulevard south to Rohret Road. Low density residential (28 dwelling units per acre) will occupy most of the remaining area. Population Approximately 1,000 people now live in this area. When developed, a total of 1,218 dwelling units and a population increase of 3,255 can be expected. Utilities There is some question as to the capacity of the sewer trunk which serves this area. A study of the sewer capacity in this area is un- derway and will be completed in fall 1978. Water and other utilities will be extended as development occurs. Trafficways Melrose Avenue, Mormon Trek Boulevard and Rohret Road will be improved where necessary to meet arterial street standards. Community Facilities A 53 acre park/school site located at the intersection of Mormon Trek Boulevard and Rohret Road provides the potential for a junior high school. If and when this school is constructed, 13 acres of the site will remain to serve as a neighborhood park for the area. A 20 acre site is shown north of Rohret Road for a potential elementary school. The School Board may prefer to use part of the West High School property 116 MICRO[ MILD By 1 JORM MICR6LAB i1')A1. ❑ . 4i :01.t!

A greenway along Willow Creek has been indicated which will be about 100 feet in width. A 6 acre commercial area is designated just west of Mormon Trek Boule- vard and north of Willow Creek. NEIGHBORHOOD VI This area is bounded by Sunset Street on the east and Mormon Trek Boule- vard on the west. It extends south from Melrose Avenue to the commer- cial use along Highway 1. Land Use The eastern portion of this area has already been developed. From Melrose Avenue south to Benton Street, apartment buildings line Westgate and Emerald Streets. Two Planned Unit Developments have been platted for this area. One is at the intersection of Melrose Avenue and Mormon Trek Boulevard; the other is along Mormon Trek Boulevard south of Benton Street. The rest of the developed portion of this area is low density (28 dwelling units per acre) residential. New development north of Aber Road will be low density (2-8 dwelling units per acre) residential. Higher density (8-16 dwelling units per acre) residential is shown south of Aber Road extending to the commer- cial use along Highway 1. Population This area as shown can accommodate approximately 6,300 population. Utilities The area south of Aber Road may not be immediately serviceable by sewer. A study of sewer capacity in this area will soon be completed. Water and other utilities will be extended as development occurs. Trafficways The entire Mormon Trek Boulevard will eventually be improved to arterial standards. Melrose Avenue and Benton Street will serve as east -west arterials. Sunset Street will serve as an arterial extending south from Melrose Avenue. Community Facilities Villa Park, which is 6.5 acres, and the 27.2 acre Willow Creek Park presently serve this neighborhood.

Land Use Existing land use includes older detached single-family dwellings (many converted to multiple family use), low-rise apartments, commercial use along Gilbert and Burlington, and a rail switching yard. Moderately high and moderate density residential uses are proposed for existing residential areas, commercial and industrial use may continue as they now exist. Population Total potential population is 1,580 persons. Utilities This neighborhood is adequately served by sanitary sewers and other utilities. Trafficways No new trafficways are proposed. Existing major trafficways include Burlington, Gilbert, Bowery, Dodge, and Governor. Community Facilities Existing community facilities include the Close Mansion at the corner of Gilbert and Bowery which serves as a Senior Center for Johnson County. This area is deficient in neighborhood parks by 8 acres. However, it is unlikely that an 8 acre tract can be acquired in this already developed area. A smaller park of 1 to 3 acres may possibly be acquired as re- development occurs. A buffer between the residential area and the rail switching yard should also be provided. NEIGHBORHOOD IX The area referred to as Village Green is bounded by Scott Boulevard on the east, by the Southeast Industrial Park on the south, by Muscatine Avenue on the north and by Mercer Park on the west. Land Use The entire Village Green area is shown as low density (2-8 dwelling units per acre) residential. Population The total population potential for Village Green is estimated at 2,430. Present population of the area is about 1,000. 119 MICROFILM BY JORM MICR46LAB A-101 MILROFILMED BY JORM MICROLAB CEDAR RAPIUS AND UL} MUINL�, IUAN Utilities Currently, there is a problem in providing this area with sewer service. This problem will only be solved when one of three conditions are met either a new relief sewer will have to be extended from the new plant to the Fairmeadows lift station, or improvements will have to be made to the existing downstream trunk sewer, or some mechanism for temporary storage of sewage during peak loading will have to be implemented. Trafficways Scott Boulevard will be constructed to primary arterial street stand- ards. Muscatine Avenue and First Avenue will continue to serve as arterials. Community Facilities Mercer Park, a community park, adjoins this neighborhood. A 12 acre park has been proposed to serve as a neighborhood park. A greenway has been shown buffering Village Green from Scott Boulevard and the South- east Industrial Park. t NEIGHBORHOOD X This area is bounded by U.S. 6 on the north, Sycamore Street to the east, the city limits to the south and S. Gilbert Street (Sand Road) to the west. Park of the northwest portion of the area is not residential J and is described elsewhere in this appendix. Land Use Existing land use in the area of approximately 570 acres is mainly agricultural. Part of the northwest portion of the area is developed for low density residential use (2-8 DU/A), and a mobile home court is located near S. Gilbert Street to the northeast. An area of medium density housing (8-16 DU/A) is located east of the K -Mart commercial area, south of U.S. 6.

A new street, Lakeside Drive extension, joining these two arterials and located approximately at the existing city limits is also planned as a secondary arterial street to serve this area. Community Facilities q A new elementary school west of Wetherby Park is planned to serve this area in the future. An additional neighborhood park of approximately ten acres on the west side will serve the higher density residential area. In addition, ten acres of neighborhood park land will be avail- able as a buffer north of the new sewage treatment plant. 7 Commercial areas serving this neighborhood are located centrally to the north (K -Mart area), to the northeast (Sycamore Mall area), and a neighborhood commercial center located in the northeast corner of Neighborhood XIII is proposed. NEIGHBORHOOD XI area isnded limits n thethe north, Lakeside Drive as east and south, and Sycamoreextended Street to the west. u Land Use Existing land use in the area of approximately 288 acres is mainly single-family residential, though the east portion of this area is multi -family apartments (Lakeside Apartments). Wood Elementary (8.2 u acres, maximum enrollment 450) is located in this neighborhood, as is Fairmeadows Park (4.9 acres). Proposed land use is low density (2-8 DU/A) residential for most of the area, with medium density (8-16) DU/A) residential planned for the eastern edge of the neighborhood, including Lakeside Apartments. V Population The plan projects a total potential population of approximately 3,700 for this neighborhood. Utilities The existing sewer capacity is virtually exhausted in this neighborhood. However, increased sewer capacity is possible through improvement of 121 i 141CRDf IL14ED By JoRM MICR46LAB IAILROFILMED BY JORM MICROLAB CEDAR RAPIDS AND ULS MUINL�>, IUviA downstream trunk sewers, building a relief sewer from the new sewage treatment plant to the Fairmeadows lift station, or sewer storage of some type. Trafficways Sycamore Street and Lakeside Drive as extended are planned as secondary arterial streets. Community Facilities A neighborhood park of approximately fourteen (14) acres is planned in the southwest corner of this neighborhood. This park will serve the increased population of the neighborhood and act as a buffer from the intersection of Lakeside Drive and Sycamore Street and the neighborhood commercial center that is planned for the southeast corner of this intersection. NEIGHBORHOOD XII This area on the south side of Iowa City is bounded by Sycamore Street to the east, the southern bypass to the south, S. Gilbert Street to the west and Lakeside Drive as extended west along the existing City limits to the north. Land Use Existing land use in this area of approximately 425 acres is largely agricultural, with a few single family homes. The topography is rel- atively flat and much of the land is classified as "prime agricultural". Proposed land use for the area is largely residential, with about 80 acres of the northeast corner adjacent to S. Gilbert Street and Lakeside Drive extension being the site for the new sewage treatment plant. About 72 acres south of the proposed sewage treatment plant are planned for medium density (8-16 dwelling units per acre) residential housing. Residential densities for the rest of the area are at a low density of 2-8 DU/A. Population A total potential population of approximately 4,780 persons is projected for this neighborhood. Utilities None of this area can be served by existing sewer capacity. However, as soon as the new sewage treatment plant is completed, the whole area will be serviced very economically since it is adjacent to the new plant. Other services will have to be extended into the area. 122 I41CROUILME.D BY 1 JORM MICR+LAB A C M MiLRUFILMED BY JORM MICROLAB CEDAR RAPIDS AND UES MUINLS, :UvJA Trafficways n South Gilbert Street, southern bypass, Sycamore Street and the extension of Lakeside Drive are all planned as arterial streets.

Density dwlling units per acre) residential ofsixteen to twenty-four dwelling units per acre is indicated for the northwest corner of the neighborhood, adjoining a potential commercial center. Population Total potential population is estimated at 5,524. Over 1,000 people presently live in the mobile home park. Utilities The sequencing map shows the extension of sewer service to this neigh- borhood aPhase uture. Waterand other which seven utilitieswill be extendedas development f occurs.

On the west boundary, Sycamore Street will be improved and extended south to the bypass. On the northwest, a new arterial will be constructed along the city limits (as an extension of Lakeside Drive). Community Facilities A 10 acre neighborhood park is recommended southeast of the mobile home park. An 18 acre park is shown separating the 8-16 dwelling units per acre density from the lower density (2-8 dwelling units per acre) resi- dential area. The neighborhood is buffered by greenways from U.S. 6 and the south bypass. A commercial center is shown in the northwest corner of this neigh- borhood. This center would serve the two southernmost neighborhoods and portions of the neighborhoods directly south of U.S. 6. Population in this trade area will be over 10,000. 124 MICROFILMED BY JORM MICRd)LAB crane; RA;:I. • I;Is, •10r11s `• n i MICROFILMID BY JORM MICROLAB Ps CEDAR RAPIDS AND DLS MOINLS, IUvJm CRAXACTERISTICS OF DEVEIOPINO NEIGIIRON0003 FOOTNOTES 1 173 Rea ldmtlal Acral % 0.5 W/A 767 W's.

Ca, I•liUkOl IUILD BY JORM MICROLAB CEDAR RAPIUS AND DLS 1-WINLI), IJ++ll TRAFFICWAYS PLAN (, INTRODUCTION. This trafficways plan represents a street system designed to serve the needs of Iowa City by the year 2000. This plan is not expected to be fully implemented by 2000, but it includes some projects which will likely be built, and corridors that should be protected. The functional classification of the streets is intended to ensure this protection by reservation of sufficient right-of-way for eventual street construction. The plan is based on the assumption that new urban in- tensity development will take place largely within the existing city limits plus the Ralston Creek and Willow Creek watersheds and the area immediately south of the city limits and east of the proposed sewage treatment plant. A map of the trafficways plan is contained on the page following the table of functional classifications of streets. FUNCTIONAL CLASSIFICATION. Functionally, trafficways need to fulfill two roles: circulation and access to property. The trafficways plan establishes a functional classification of primary arterial, secondary arterial, collector and local streets, with each classification repre- senting a shift in relative importance of the circulation and access functions. A. PRIMARY ARTERIAL streets' principal function is to provide for vehicular circulation. Primary arterial streets should be designed to carry large volumes of traffic (15,000 or more vehicles/day) and should form a continuous system of a peripheral ring and radial streets serving the core of the city. Primary arterial streets serve as the principal truck routing system of the community and, because of the adverse effects of trucks and large volumes of traffic, they should be well buffered with landscaping and ample rights-of-way. Access to primary arterials should be strictly limited, and driveways should not be permitted to have direct access to primary arterials. B. SECONDARY ARTERIAL streets serve a dual function of circulation and access, with circulation taking precedence. Secondary arterial streets should be developed to carry large volumes of traffic (5,000-15,000 vehicles/day) in a grid and radial pattern which supplements the primary arterial system. Secondary arterial streets should offer direct property access only to large indus- trial, commercial, institutional, and multi -family residential sites and should be buffered from residential uses by ample land- scaped transitions. Driveways should not be permitted to have direct access to secondary arterials. C. COLLECTOR streets serve the dual function of circulation and access, with access taking precedence. Collector streets should be designed to carry moderate volumes of traffic (1,000-5,000 ve- hicles/day) relatively short distances to and from arterial streets. The collector street system should be discontinuous, with street lengths no longer than one kilometer (0.6 mile) as a general rule. Collector streets should provide access to all types of land use, however access for single-family residences should be onto local streets. 129 Y :4IC ROf ILMCO OY JoRM MICR6LAB miuROFILMED BY JORM MICP,OLAD CEDAR RAPIDS AND ULS NU1NL�, :N» D. LOCAL streets serve the function of access to property. Local streets should be designed to carry only small volumes of traffic (up to 1,000 vehicles/day) and to discourage both high-speed and high-volume use. The local street network should be relatively continuous, but individual streets should neither extend much beyond one kilometer (0.6 mile) in length nor have direct access to primary arterial streets; access to secondary arterial streets should be minimized. Local streets should provide access to all land uses except the most intense uses such as industrial, in- stitutional and commercial. TRAFFICWAY DESIGN STANDARDS. The following design standards are recom- mended for the Iowa City trafficway system. The primary need for these design standards is to ensure that the proper right-of-way width is obtained. The designation of primary and secondary arterials and collector streets in advance of development in order to limit access along these routes is an important consideration. Trafficway design standards should be required within the two mile extraterritorial jurisdiction as appropriate. The pavement design should be in accord- ance with public works design standards �Pro�osed_ Desi n Standards for Public Works Im r2vp_ lents in � wa City, Iowa, Apri 1975 as amended rom time to titime. Severe h sical restraints, identified need for neighborhood protection, and similar factors may require modifications of these standards when applied to specific areas. Existing arterial and collector streets which are below standard will not be widened unless noted otherwise on the Land Use Plan Map. The typical cross- sections shown on page 132 , do not include turning lanes; the right-of- way width would remain the same if turning lanes were added. (Note: These standards have been modified from the standards published in the Iowa City Plan: Trafficways Report included in Appendix A.) 1. Primary arterial streets are to be developed as boulevards or expressways, with a median separating opposing flows of traffic. At intersections medians will be used to provide left turn storage lanes. No parking is permitted on primary arterials and maximum acceptable grade is 8%. Access will be controlled and driveways will not be permitted to have direct access to primary arterials. The median should be designed to protect vegetation from salt spray and snow removal operations. 2. Secondary arterial streets should be designed as four -lane facil- ities except in commercial areas where they, may be designed as three -lane facilities. At intersections with other arterial streets it may be desirable to add a lane for left turn movements which preclude some landscaping for one-half block in each di- rection from the intersection. Access will be controlled and driveways will not be permitted to have direct access to secondary arterials. No parking is permitted and maximum acceptable grade is 8%. A twenty-five foot pavement (two -lanes) centered in the right- of-way should suffice as an interim construction project, in newly developing areas. 130 Id I CROF I LMLO BY DORM MICR46LAB M MILROF ILMED BY JORM MICROLAB CEDAR RAPIDS AND ULS MUINLS, IUrG� Collector streets should be developed with a 36 foot wide paving. This paving width would provide parking on both sides and two narrow traffic lanes when traffic volumes are relatively low. In the future, as traffic volumes warrant a change, parking on one side would be removed to provide a more efficient two-lane facility for a collector street. If the Council does not desire to provide on -street parking along collector streets, a 28 -foot facility (two - lanes) would be adequate. At intersections with arterial streets, a left -turn lane should be provided by eliminating parking for one- half block on 36 foot wide streets, or by widening to three lanes on two-lane facilities. Collector streets should not be longer than 0.6 miles to discourage through traffic and maximum grade should not exceed 10%. Driveway access for single-family resi- dences should be provided on local streets. The primary local street is intended to serve residential areas which have a density greater than 1 DU/A. This type of street should not be longer than 0.6 miles and should not provide a direct route between streets of a higher classification. Parking may be permitted on both sides of the street and maximum acceptable grade is 12%. For areas at a density of 8 DU/A or greater, a 36 foot pavement with a 66 foot right-of-way should be provided if parking on both sides is desired. The rural local street may be developed in areas with single-family residential densities less than or equal to 1 DU/A. This type of street is ideally suited to areas of steep topography, therefore, maximum grades of 20% are acceptable, provided transitions do not exceed 12%. The length of this type of local street should not exceed 0.6 mile. On -street parking would not be allowed. A side- walk on one side only may adequately serve the neighborhood's pedestrian needs.

If the project concept is to be constructed in various stages (completed in more than one letting, and/or more than one construc- tion season), please present your anticipated schedule. 13. 'rhe MOT and FIIWA have concurred that this project is a type II non -major action with significant right-of-way acquisition. 14. Proprietary Equipment. The City requests authorization to use Automatic Signal's NIF-80 controller to control this intersection. The use of proprietary equipment is being requested for two primary reasons. At this time the City has in use eleven of these devices. The City's maintenance personnel are trained to maintain and trouble- shoot this device. A different device would require new training. The second primary reason for requesting the use of proprietary equ.ipnrent .is the City's on -hand supply of spare controller components. If the use of proprietary equipment is disallowed the City would be required to acquire additional components to maintain this installation. q,._•�(' :41CRef IL14ED BY JORM MICRbLA6 {iid'I ao 'd C, 140 R1f i.

Pavement Thickness Design. Design Method - "ASSIIT0 Interim Guide for Design of Pavement Structures". Traffic Distribution - See enclosed "Urban Pavement Determination" for traffic distribution and 18k equivalent single axle load per day (GSAL), 20 year analysis. For Design - CAR = 3 K = 100 pci Servicability index, PT = 2.5 Modulus of rupture = 575 psi Working stress = 575 (.75) = 431 pci Assume d = 8" .'.18k GSAL/day = 193 I From rigid pavement thickness nomograph d = 8" j 8 inch non -reinforced P.C.C. pavement on compacted subgrade is proposed for the total length of the project due to the heavy truck traffic from adjacent commercial and industrial development. Utilizing the traffic projections of Iowa DOT and the "AASII'1'0 Interim Guide for Resign of Pavement Structures, 1972" 8" depth rigid pavement is justified for the portion of the project from the intersecti.on of Gilbert Street and Stevens Drive north to the project terminus. For the portion of the project south of the Stevens Drive intersection, the above referenced sources would suggest something less than 8" depth pavement. however, the City maintains that the truck traffic percentage forecast south of Stevens Drive is unreasonably low. The section from Highway 6 south to Stevens Drive is to carry an estimated 9,910 ADT with 7% trucks or 695 trucks. The section south of Stevens Drive shown to carry an estimated 5,000 ADT with 4% trucks or 200 trucks. The City maintains that this imbalance (700 trucks versus 200 trucks) is unrealistic. The number of trucks through both of the sections should very nearly be the same. 141CROFILMED BY JORM MICR4�LAB MICROFILMED BY JORM MICROLAB CEDAR RAPIDS AND DES MOINES, IO1•IA 6 of 8 1 17.

LID of 70 dBA and 75 dBA will be beyond the right-of-way limits. Although undesirable, known methods of noise attentuation will not be f.ensi.bl.e due to right-of-way restrictions and excessive cost per benefit. Such practices ns construction of a noise barrier would be, for aesthetic reasons, less desirable than the higher sound levels in an urban environ- ment for this type of facility. it is expected that the truck traffic will use the facility primarily during the daylight hours since much of the volume is agricultural find construction oriented Currently, only one home,set hack 200+ feet from the right-of-way, exists on the proposed route; the remainder being commercial property. A copy of this noise analysis :Ind associated (lata will be forwarded to the City Planning find Zoning Commission for consideration in future land use decisions.

Although such noise intrusion will he relatively short in duration it could be annoying at times. Ileavy machinery associated with the construction will be the main source of noise. Contractors will be required to use the best muff Ling devices that are available under current technology. Machinery is expected to be in good working order to limit engLne noise. The noiser activities will be restricted to daytime hours. The above provisions will be included in contract documents. 18. 'Traffic Signal Guidelines A) Accident Data - 175, 176, '77 attached. B) Volumes - as per concept statement. C) Pedestrian Volumes - non-collected,known to be minimal. D) Geometries - as per concept statement. i I E) Pavement Markings - Dashed white lane lines will be used to c7incate ai�Multiple lane approaches. Arrows indicating turn lanes will be used in the appropriate lanes. The curbs of raised medians will be painted for delineation. P) Traffic Controls - The City anticipates no turning prohibitions will be required. Both U.S. Highway 6 and South Gilbert Street Will he signed"No Parking,+'. Speed limits for U.S. Highway 6 will be .posted by the fDCT; the City will sign South Gilbert Street speed limits. G) Approach Grades or�Sipnn Restrictions - All approach gra e� s are minimal.

A "No Build" Alternate would result in the following impacts: t A. A level of service "C" cannot be provided at peak hour demand; B. A safety hazard exists with the deteriorating condition of the road surface and inadequate shoulders; C. The City will have continuous and increasing maintenance costs due to the rapidly deteriorating condition of the road surface; D. The existing rural cross-section of the right-of-way is continually changing to an urban cross section, as increased development occurs, causing drainage problems. E. The existing condition of the roadway does not provide for safe and efficient movement of goods and people. New Pavement, Storm Sewer, and Related Work Using Bxisting Alignment. This alternate would result in the following impacts: A. The existing alignment consists of many sharp horizontal curves; B. Sight distance is aggravated by commercial buildings located along the front lot lines; C. The existing right-of-way width is 66 feet. This width is not sufficient to provide a safe distance between the edge of paving and the street edge of the sidewalk. D. 'rhe present alignment crosses Highway 6 with an angle of 480461, and crosses the CRISP Railroad tracks with an angle of 1 340. D. Acquiring additional right-of-way to correct existing deficiencies would require the relocation of several businesses along the route.
