Kellie Fruehling, City Clerk rmOPI o -e 5a STAFF REPORT To: Planning & Zoning Commission Prepared by: Sarah Walz Item: REZ17-00016 Date: December 7, 2017 Lincoln Elementary Addition GENERAL INFORMATION: Applicant: Iowa City Community School District 1725 North Dodge Street Iowa City, IA 52245 Contact: Luke Newton MMS Engineering 1917 S. Gilbert Street Iowa City IA 52240 Requested Action: Rezoning - Sensitive Areas Development Plan approval Purpose: To reduce the buffer requirements; to allow development within an area containing "altered protected slopes" for an addition to the elementary school Location: 300 Teeters Court Size: 3.6 acres Existing Land Use and Zoning: Elementary school; P-1 Surrounding Land Use and Zoning: Surrounding properties are all zoned RS -5 and developed with single-family residential; property to the northwest, is a fraternal group living use (nonconforming). Comprehensive Plan: The Comprehensive Plan identifies this area as appropriate for a school or other institutional use. File Date: October 26, 2017 45 Day Limitation Period: December 10, 2017 BACKGROUND INFORMATION: The Lincoln Elementary School property consists of approximately 3.6 acres with frontage on four streets: Teeters Court, Rider Street, Lee Street and River Street (see exhibit 1). The existing building sits at the north end of Teeters Court and atop a hillside with 30 feet of elevation change between the back (east side) of the existing building and the lower parking lot accessed from 2 Rider Street. The steep hillside, which runs north to south through the northern half of the property, is an unused portion of what is a relatively small school site (by ICCSD standards) and presents a challenge to development. The original school building, constructed in 1926, has been added onto five times over the intervening decades (see exhibit 2). These additions extended the building further to the south and east. Eight parking spaces are currently provided near the front entrance (an adjacent parking area, located on the west side of Teeters Court serves another property—the medical fraternity). An additional parking area with 28 spaces was constructed off Rider Street in the late 1980s. This portion of the property is not readily accessible to the school building—the rear entrance is accessed via a 55 -step staircase built into the slope. As part of a district wide facilities plan, the Iowa City Community School District (ICCSD) proposes a complete renovation of the existing school building and the construction of a major new addition that will provide space for a new gym and cafeteria, modern kitchen, media center extension, restrooms, a dedicated office and storage area for the before- and after-school program, and an ADA accessible (at -grade) entrance from River Street (see exhibits 3- 7).The proposed plan also provides an expanded parking area. The proposed addition and expanded parking area on River Street attempts to address several shortcomings of the school site: Limited ADA access: The proposed site plan preserves limited level outdoor play space; approximately 1.0 acre on the southern portion of the site is preserved as playground. Provides ADA accessible entrances from both Teeters Court and River Street Constrained bus and vehicle circulation: Buses currently drop off students on Rider Street and turn around in Black Springs Circle. New entrance off River Street will allow buses access and turn around adjacent to the school entrance. The applicant has used the "Good Neighbor Policy", hosting a neighborhood meeting and discussions with area residents on November 8 at Lincoln Elementary. ANALYSIS: The applicant is requesting a Planned Development rezoning for a Sensitive Areas Development Plan in order to construct the school addition on a portion of the property that contains regulated sensitive features. A Level II Sensitive Areas Review, a type of planned development, is required due to proposed disturbance of steep, critical, and previously altered protected slopes and a request to reduce a required wetland buffer. General Planned Development Approval Criteria Applications for Planned Development Re -zonings are reviewed for compliance with the following standards according to Article 14-3A of the Iowa City Zoning Ordinance. 1. The density and design of the Planned Development will be compatible with and/or complementary to adjacent development in terms of land use, building mass and scale, 3 relative amount of open space, traffic circulation and general layout. Land uses proposed and general layout—The proposed addition to the Lincoln Elementary School is part of the Iowa City Community School District's 10 -year Facilities Master Plan. It is designed to bring equitable learning spaces to all buildings in the district, improving the structure and amenities of the District's older buildings while preserving the historic qualities of those structures. The design of the proposed addition provides required ADA accessibility, classroom space, and new art, music, and gymnasium space. The location of the addition within the property also preserves ADA accessible playground area to the south of the school building and opens up potential for accessible use of the northern portion of the property along Rider Street for additional outdoor uses. The presence of the school is viewed as an essential anchor to the surrounding neighborhood and the applicant has held numerous public meetings announcing plans to expand the school building. Mass and Scale — By its very nature a school building and the proposed addition with be of a different scale and mass than surrounding single-family housing. However, the proposed addition attempts to integrate the building within the surrounding landscape. The new addition maintains the current roof height and is setback more than 140 feet from its east property line (Lee Street frontage) and 37 feet from the rear of the lot of the single-family property at 225 Lee Street, where the addition will replace a "temporary" classroom Open space — The proposed addition preserves roughly an acre open space for playground use on the south side of the property along Teeters Court and Rider Street. Playgrounds also serve as neighborhood park space when school is not in session. Traffic circulation — Currently buses pick up and drop off along Rider Street, which has a pavement width of 24 -feet, and turn around on Black Springs Circle. Parking and turn around on Teeter Court (another 25 -foot street) are quite limited. The addition makes possible an ADA accessible entrance from the east side of the school and provides an expanded parking area off of River Street. In staff's view, this will improve traffic circulation for pick up and drop off at the school, allowing buses more immediate access to the school building and to load and unload within the parking area rather than on street. 2. The development will not overburden existing streets and utilities. City sewer and water are already available to this property. Capacity is adequate to accommodate development of the addition. Onsite storm water management is required for any expansion of impermeable surface. The applicant currently proposes to underground storage beneath the parking area, however underground tanks may hot be installed over sanitary sewer lines as currently shown. 3. The development will not adversely affect views, light and air, property values and privacy of neighboring properties any more than would a conventional development. While the proposed development will be a significant change to the site, staff believes that the proposed development is not a significant departure with regard to views, light and air, property values and privacy of surrounding single-family properties and extends the life of a neighborhood school, which is viewed as a vital institutional anchor for residents of the neighborhood. 4. The combination of land uses and building types and any variation from the underlying zoning requirements or from City street standards will be in the public interest, in harmony with the purposes of this Title, and with other building regulations of the City. All planned developments must comply with all the applicable requirements and standards of the underlying zoning district and the subdivision regulations, unless specifically waived or modified through the planned development process. Variations to the dimensional requirements of the underlying base zone and subdivision regulations are allowed: • to facilitate the provision of desired neighborhood amenities or open space; • to preserve or protect natural, historic, or cultural features; • to achieve compatibility with surrounding development; or • to create a distinctive or innovative neighborhood environment for area residents. The decision to renovate and expand Lincoln Elementary is the culmination of multi- year planning process that encompassed significant public input and, most recently, a district wide vote that approved a bond for a 10 -year facilities master plan. Staff believes that maintaining Lincoln Elementary as a viable neighborhood school is a public good that is widely supported within the Iowa City community and the school district. Level 11 Sensitive Areas Review The applicant has applied for approval of a Sensitive Areas Development, a type of planned development. The purpose of the Sensitive Areas Ordinance is to permit and define the reasonable use of properties that contain sensitive environmental features and natural resources, and allowing reasonable development while protecting these resources from damage. The following paragraphs describe the impact this development will have on the sensitive features of this site (see Sensitive Areas OPD plan). Steep. Critical, and Protected Slopes - The purpose of regulating development on and near steep slopes is to: 1. Promote safety in the design and construction of developments; 2. Minimize flooding, landslides and mudslides; 3. Minimize soil instability, erosion and downstream siltation; and 4. Preserve the scenic character of hillside areas, particularly wooded hillsides. The submitted sensitive areas site plan shows that the northernmost half of the school addition and a portion of the expanded parking area extending into a sensitive slope and required buffer area. The development activity will disturb a significant portion of the steep, critical, and protected slopes: 28% of the steep slopes; 63% of the critical slopes; and 32% of the protected slopes. The 5 sensitive areas ordinance requires that disturbance of steep and critical slopes be minimized and sets a maximum of 35% for critical slope disturbance with administrative staff approval. Disturbance beyond this threshold is proposed, which has triggered the requirement of this Level II Sensitive Areas Review with Planning and Zoning Commission review and City Council approval required. Development activity is not allowed on protected slopes or within the 50 -foot buffer required around protected slopes, unless the slopes were previously humanly altered. In addition, disturbance of altered protected slopes or a reduction of a protected slope buffer may only be approved if a geologist or professional engineer demonstrates to the satisfaction of the City that the proposed development activity can and will be designed to eliminate hazards and will not undermine the stability of the slope or the buffer area. The applicant has indicated that the slope located between the building and the parking area has been humanly altered as various additions and building/site improvements were made over time and is requesting permission to encroach into protected slope. The applicant has submitted evidence to support this assessment. A topographic survey performed for the applicant earlier this year indicates that the that the hillside has a fairly consistent percentage of slope from top to bottom along its length. The majority of the slope meets the classification of critical slope (between 25%-40%) with the top of back and toe of the slope being less steep and below the threshold of "critical" slope. The slope also has a very consistent shape at its toe, sloping from south to north. The attached illustrations provided by the applicant show the changes in the slope and suggest that the construction of the steps along the slope the parking lot cut into the hillside, creating a steeper slope in this area. Moreover, a stormwater drainage pipe running from the exiting building northeast to the parking area is buried underground within this slope. The School District has contracted with a geotechnical engineer to perform and analyze soil borings on the hillside, however because the changes to the slope involved grading rather than fill, it is likely the borings will be inconclusive (see exhibit 8: Altered Slopes memo and supporting documents). It is anticipated that the new school addition will be supported on shallow concrete spread footings. The spread footings will extend to frost depth at 42 inches below grade. The proposed addition will connect to the east side of the existing school building, with the main level floor matching the existing building floor elevation. The addition's lower level will exit to grade of the east side of the addition approximately 30 feet lower than the existing school building main level. Due to the depth of excavation needed to construct the addition, the addition incorporates an earth retention system within the foundation wall system. The proposed system includes soldier piles with tiebacks that anchor the foundation wall into the existing ground slope. Certification by a licensed structural engineer will be required at the time of building permit application to ensure the stability of the building. Three mature oak trees and several evergreens located near the proposed addition will be removed as part of the project. The applicant is proposing to replace these with 10 new native trees—white, red, and bur oaks. New trees currently shown located within the parking area may need to be relocated away from easement for sanitary and storm sewers. There is ample space around the parking area perimeter to locate required parking area shade trees. Mature trees to the east and southeast of the addition, along the abutting residential properties, will be preserved. A tree protection plan should be submitted and approved at the time of the final OPD plan. The submitted landscape plan shows that the applicant will meet the S2 (low shrub) screening requirement along the north and east perimeter of the parking area. Storm water management: Stormwater management will be handled on site with underground storage located beneath the parking area. City engineers have indicated that the underground structure may not sit overtop public utilities—sanitary sewer. SUMMARY: Staff believes there is compelling evidence that the hillside to the east of the existing school building has been humanly altered over time with various additions and improvements to the school site. While the proposed plan does call for substantial disturbance (excavation and grading) to a sensitive slope, the school building is being engineered within the hillside to prevent hazards, such as erosion, and the site plan shows replacement of native trees that have long been a part of the character of this unusual school site. The planned upgrades to the existing school preserve limited outdoor play space, achieve ADA accessibility to all portions of the building and property, and improve traffic circulation. In doing so, the plan extends the life of one of Iowa City's oldest schools within a walkable neighborhood context and is therefore in the public interest and fulfills one of the goals of Iowa City's Comprehensive Plan. STAFF RECOMMENDATION: Staff recommends approval of REZ17-000016, a Sensitive Areas Development Plan subject to the following conditions: Substantial compliance with the development plan submitted. Establish easements for the stormwater management area. Establish any easements not currently existing for storm sewer and sanitary sewer. Certification by a licensed structural engineer will be required at the time of building permit application to ensure the stability of the building. DEFICIENCIES AND DISCREPANCIES: 1. Final soil report from Terracon required. 2. Technical discrepancies and deficiencies as noted by the City Engineer and water department: a. Provide stormwater calculations. b. An easement is needed for stormwater management area. c. The underground detention chambers/stormwater management area cannot be over the City's sanitary sewer d. Easements to be provided for the City's storm sewer and sanitary sewer that run thru the property. e. Underground detention chambers need to be outside the easement for the City's storm sewer. f. Trees may not be located in easements for underground detention chambers, storm sewer, or sanitary sewer (Trees in parking lot islands). ATTACHMENTS: 1. Location Map 2.

MExperts in Planning and Development Since 1975 MEMORANDUM To: City of Iowa City Staff Date: Nov. 6, 2017 Subject: Lincoln Elementary Sensitive Areas — Altered Protected Slopes 1917 S. Gilbert Street Iowa City, Iowa 52240 319.351.8282 mmsmnsultants.net mms@mmsconsultants.net Lincoln Elementary School is located at 300 Teeters Court in the Chautauqua Heights subdivision in Iowa City. The school site fronts four public streets, including Teeter Court, Rider Street, Lee Street and River Street. The original building was erected in 1926, but has received five additions since with additions in 1949, 1954, 1973, 1974, and 1988. Along with the building additions, the site has received improvements with a parking lot installation, and playground improvements. The school building sits at the north end of Teeters Court and at the top of an east -facing hillside with 30 feet of elevation change down to a valley floor and the staff parking lot which is accessed from River Street. Lincoln Elementary School is scheduled to receive upgrades as part of the district wide Facilities Masterplan and the design work is currently underway for those improvements. The improvements include a complete renovation of the existing school building and additions of a new Cafeteria, Media Center and Gymnasium with a new entrance accessed via an improved River Street parking lot. The hillside between the building at the top and the parking below is a largely unused and portions of the hillside are seemingly untouched except for the north end of the hillside adjacent to the parking lot and steps connecting it to the school building. This section of the hillside was manipulated for the installation of those site improvements. A topographic survey was performed in July of 2017 in preparation of the planned improvements. The topographic survey revealed that the hillside has a fairly consistent percentage of slope from top to bottom all along its length. The majority of the slope meets the classification of 'critical' slope having a percent of slope between 25% and 40% with the top of back and toe of slope being less steep and below the threshold of 'critical' slope. The slope also has a very consistent shape at the toe of slope arcing from south to north. The surveyed toe of the slope is called out in the attached image and delineated in with a solid black line. The assumed former or natural toe of slope is delineated with a green line and is best -fit along the surveyed toe of slope. A comparison of these two lines reveals an area of impact at the toe of the slope. The parking lot and steps were cut into the hillside when constructed and have created a steeper slope in those areas. The hillside adjacent to the corner of the parking lot is greater than 40% slope and therefore classified as 'protected'. However, the topography shows that portion of the hillside was cut at the toe and therefore the steepness of the slope is a product of grading the slope to blend the cut grade to the natural grade. And, the slope of this portion of the hillside at the toe is above 40% and not consistent with the rest of the hillside which is less steep at the toe of the slope and its lower elevations just above the toe. Additionally, the hillside has a number of large tree stumps and was once wooded, but no stumps are present in the portion of the hillside that was cut. Finally, the slope was also impacted by a storm line installation from the building to the storm pipes under the parking lot below. The identified slope on this hillside is not a 'Protected slope', but rather an 'Altered Protected Slope' as it is the result of manmade activities. The proposed building addition impacts the delineated 'Altered protected slope' and adjacent critical slopes. The School district has contracted for a geotechnical engineer to perform and analyze soil borings on this hillside, but these may be inconclusive as the 16 Vr L M1917 S.

IOWA 2 T IW Additional information for Lincoln Elementary Variance Application - Existing condition of the hillside The Lincoln Elementary school on the East side of Teeter Court is located adjacent to and atop an East facing hillside of +30 feet of elevation. Upon review of historical aerial photos (Johnson County PIV/GIS website) and inspection of the existing trees, the hillside does not appear to have been regraded at any point, except for the portions of the hillside directly North and East of the Northern end of the school building. The slope of the unaltered portions of the slope is a fairly consistent ±35%. The construction of the building and site elements has impacted the site and the hillside since the building was built in 1929. The building has received a number of additions over the years with each enveloping more of the hilltop. The original building is the most evident impact on the terrain along its North and East walls, with cut and fill operations manipulated the natural slope. Other additions to the school have impacted the site and hillside, as there are roof drains transecting the hillside to the storm sewer below the base of the hill. The addition of the parking lot at the base of the hillside has altered the slope as the toe of the slope was cut back to build out the SW corner of the parking lot. On-site inspections and the topographic survey suggest the grading cut was "chased" up the hillside a significant distance. This grading work increased the percent of slope on this portion of the hillside beyond what is apparent and typical over the rest of the (unaltered) hillside. There is also a roof drain pipe that was trenched in this same cut area that extends from the building to the storm sewer under the parking lot. Likewise the installation of steps connecting the parking lot to the building cut the slope adjacent to them and Increased the percent slope over the preexisting slope. - Site (lower parking) is currently not compliant with ADA parking standards The off-street parking lot for the school is accessed from River Street and is at the base of the hillside. There is no accessible route from the parking lot to the building and there for no accessible parking stalls. This lot does contain 27 spaces, and when coupled with the 10 on -street parking stalls on Teeters Court, the overall school site is deficient of the minimum ADA compliant parking stalls. A building expansion over the hillside to the elevation of the lower parking lot along with an improved parking lot will provide for more accessible parking and access to the building. Existing school bus site access and student drop-off/ pickup procedures The current Bus loading/unloading operation for Lincoln Elementary takes place on the city street. The buses do not travel on Teeters Court as there is no cul-de-sac bulb or other means of turn- around at the end of the street. The students must walk to the far south end of the site to reach the buses parked on Rider Street. As there is no bus pull off on the street, the traffic is Impacted by the queued busses, as well as the parent drop-off/pick-up traffic. An improved lower parking lot would provide for an off-street bus loop and safer situation for students and vehicular traffic as well. - Describe the interim and final grading It is expected that during construction, the grading work and trenching work necessary to install the foundations for the building addition would be done with benched excavation and side slopes not exceeding the maximum safe slope determined by the geotechnical engineer and/or 3.5:1. In concert with the cut for foundations, portions of the site may require temporary sheet piles or other shoring measures. Upon completion of building walls and waterproofing measures, the disturbed area around the building will be backfilled graded to a consistent 3.5:1 slope with steeper slopes only planned as necessary to tie back into the existing undisturbed hillsides. A retaining wall is part of the proposed construction on the south side of the building addition to correctly achieve the elevations needed along the building. No retaining walls are currently planned for the hillside adjacent to the north of the building addition. Iowa City School District Lincoln Elementary School Renovation & Addition Design Development Structural Design Narrative Project Scope: The project consists of an addition and renovation to the existing Lincoln Elementary School building located in Iowa City, Iowa. The new addition will be located to the east of existing elementary school building. The addition will house a gymnasium, storage, restrooms and mechanical areas at the lower levels with a new media center and cafeteria areas located on the main level. Foundations: A geotechnical investigation has not yet been completed for the project. It is anticipated that the new additional will be supported on shallow concrete spread footings. The spread footings will extend to frost depth at 42 inches below grade. The existing site grade has a significate slope across the project site. The additional will connect to the existing building on the west side of the addition with the main level floor matching the existing building floor elevation. The addition's lower level will exit to grade of the east side of the addition approximately 30 feet lower than the existing school building main level. With the proximately of the new addition to the existing building and the depth of excavation needed to construct the addition it is recommended that an earth retention, shoring, system is provided. It is proposed to incorporate the earth retention system with the gymnasium foundation wall system. The proposed system includes soldier piles with tiebacks that anchor the foundation wall into the existing ground slope. Wood lagging would span between the soldier piles and the lagging would act as the temporary earth retention system. The concrete foundation wall would be placed against the wood lagging and soldier piles. Headed studs will be welded to the soldier piles to anchor the concrete foundation wall to the soldier piles. In the final building condition the soil loads will be resisted by the concrete foundation walls, which will transfer the load to the soldier piles, which will resist the soil load by using tieback anchors into the existing ground slope. Alternate earth retention/foundation wall systems will be investigated. Slab -on -Grade: The slab -on -grade for the project is planned to be a reinforced concrete slab -on grade. These slabs will be reinforced utilizing steel welded wire reinforcement. The floor slab shall bear on an appropriate vapor retarder that is placed over the lop of free draining crushed aggregate. This crushed aggregate layer shall be a minimum of 6 inches below the floor slab on grade. Proper control joints shall be cut into the slab -on -grade at an appropriate spacing to control shrinkage cracks. At the lower level it is possible, depending on the recommendations by the project geotechnical investigation, that a subdrain system will be installed below the floor slab to control the possibility of perched water occurring due to infiltration. This subdrain system would consist of a series of drain tiles spaced across the floor slab and would be located in granular material trenches. These pipes would be collected and routed to the storm sewer. Elevated Floor Structure Framing: The elevated floor structure framing over the gymnasium will consist of a topping slab over precast concrete double tees. The elevated floor structure at the mechanical mezzanine and the corridor area will consist of a topping slab over precast concrete hollow core slabs. The precast concrete members will be topped with a 3° thick concrete topping.

REZONING ITEM (REZ17-00016): Discussion of an application submitted by Iowa City Community School District for a Sensitive Areas Development Plan (rezoning) to allow modification of a protected slope for the construction of a proposed addition on the east side of the school building located at 300 Teeters Court. Walz presented the Staff Report noting that this site is the Lincoln Elementary School property and showed maps and photos of the area. The property is accessed along Rider Street, Teeters Court and River Street. There is also some frontage along Otto and Lee Streets but the property is not accessible from those streets. Along Rider Street and Teeters Court the property has a higher elevation. Walz explained that the Lincoln Elementary School site is a small school site by Iowa City standards—it is less than four acres. Most of pickup/drop off and bus access is on Rider Street. When the School District was looking at using this site and improving the neighborhood schools (which was part of what they were called upon to do with Iowa City Planning and Zoning Commission December 7, 2017 – Formal Meeting Page 2 of 6 Community School District's facilities plan) one of the goals was to extend the life of neighborhood schools. This goal is echoed in Iowa City's Comprehensive Plan and in the City Council's Strategic Plan. Walz explained that this particular school site presents some unique challenges with street access and topography. Currently the lower level of the property (off River Street) is the teacher's parking lot, which is not an ADA accessible part of the school site. To access the school from that parking lot requires one to climb 55 steps to get to the rear entrance of the school. For this reason, the portion of the property on River Street has been useable. One of the goals of the new addition is to make the entire property, which is very small, more useful and accessible. The original school building, constructed in 1926, has been added onto five times. The lower parking area with 28 spaces was constructed off Rider Street in the late 1980s. The proposal is a complete renovation of the existing school building and the construction of a major new addition that will provide space for a new gym and cafeteria, modern kitchen, media center extension, restrooms, a dedicated office and storage area for the before- and after-school program, and an ADA accessible (at -grade) entrance from River Street. The proposed plan also provides an expanded parking area and will improve the bus circulation. Walz mentioned the sensitive areas on the site noting that many of the criteria that are required under the OPD Plan (mass, scale and density of the building) do not really apply since this is not a residential use—as a school it will obviously be of a different mass and scale than surrounding residential development. Walz explained that the Sensitive Areas Ordinance is applies in areas where there are steep and critical protected slopes. The development activity will disturb a significant portion of the steep, critical, and protected slopes: 28% of the steep slopes; 63% of the critical slopes; and 32% of the protected slopes. Walz stated the applicant has demonstrated through engineer reports that the slope was altered over time with both various additions to the school and when the parking lot was constructed. The applicants have also conducted some soil studies, taken some samples, which are inconclusive but do show some fill on portions of the site. Walz stated that with this addition, a portion of the slope will actually be excavated, and the new school building will be used as a retaining wall for the remaining slope. Additionally this development will cause the removal of some mature oak trees, the applicant's intent is to replace those trees with 10 new native trees -white, red, and bur oaks. They will also add screening around the parking lot. Walz explained that there are still some outstanding issues with the site that to be resolved. The applicant needs to provide stormwater calculations and easements will be needed for the stormwater management area. The applicant is showing underground storage for stormwater but to the underground storage cannot be placed over the sanitary sewer line. The applicants is working to resolve these issues. Staff recommends approval of REV 7-000016, a Sensitive Areas Development Plan subject to the following conditions: Substantial compliance with the development plan submitted. Establish easements forthe stormwater management area. Establish any easements not currently existing for storm sewer and sanitary sewer. Certification by a licensed structural engineer will be required at the time of building permit application to ensure the stability of the building. Theobald questioned the use of native trees versus oak trees and noted there are Planning and Zoning Commission December 7, 2017 — Formal Meeting Page 3 of 6 problems with two of the oak tree species in the State of Iowa right now and asks that the tree replacements be more diversified. Walz stated the City Forester could be asked to make a recommendation if the Commission wished to make that a condition. Theobald would like to add that condition. Hensch asked if the geotechnical soils report did not definitively indicate that the slope had been disturbed. Walz confirmed that is correct. The applicant was relying on other evidence related to development activity, especially the construction of the parking area along River Street. Hensch asked if the rule was only 35% of critical and protected slopes could be disrupted without going through rezoning. Walz said that is correct and this item is before the Commission because the applicant is exceeding the 35%. Dyer questioned if there have been other projects that have disturbed areas this much. Miklo stated it is rare to have humanly altered slopes, he can think of one instance on South Dubuque Street where they could show the street was created by landfill over 100 years ago. Hensch asked when looking at the elevations if the stormwater underground storage tanks will be able to handle the area or if there would be runoff that would go to the neighbors. Walz said the runoff flows to the north but the applicant can explain how they intend to manage the additional stormwater. Hensch opened the public hearing. Luke Newton (MMS Engineering) and Sarah Huston (Design Alliance Architecture) represented the Iowa City Community School district on this project and showed the Commission the presentation that they had also shared with the community at the Good Neighbor Meeting. Hensch asked if any comments were collected at the Good Neighbor Meeting. Walz noted she attended the meeting and that all the comments were generally positive. Newton provided a copy of the comments. Huston stated that the architecture firm began by reviewing how the existing building was constructed and added onto over the various renovations and noted how that always poses interesting issues when dealing with different construction types. There is a main building as well as two temporary classrooms, one to the south and one to the east. Most of the main site area is level and the initial addition recommendation was to expand into the southern level area with a new gymnasium, new commons, accessible classrooms, and bathrooms. Another more interesting concept was to build off to the east and that was the concept the school committee unanimously voted on because they wanted to preserve the flat area which is the playground area. Huston showed renderings of what the addition will look like, it will be nestled into the hill, the lower level being the gymnasium and above that is the new media center. From the view of Teeters Court the school will remain the same scale and the addition will be viewable from the east but not overly obtrusive because it is nestled into the slope. The main entrance to the school will still be off Teeters Court and will be at the center of the building. Planning and Zoning Commission December 7, 2017 - Formal Meeting Page 4 of 6 Huston also discussed the structural engineering of the addition and how it will be built into the slope. They will use soldier piles, steel and concrete, to provide a retaining wall that then becomes the back wall of the new structure. Additionally the new gymnasium that is dug into the slope is set 20 feet off the existing structure so it will not disturb any of the foundations or walls of the existing building. Huston noted that is important because it is safer to preserve what is already there. Newton next addressed the system areas showed a rendering of the area with the different percentages of slope and the area that is the altered protected slope. He showed the storm lines that run from the building to the storm sewers that are underneath the parking lot. Hensch asked if Newton could address how the underground storage of the stormwater will handle the runoff. Newton stated that with the increased impervious areas it will create more overland runoff and as required by City Code they will need to retain that runoff and the underground basin works similar to an above ground stormwater basin. Underground there is a system of large pipes all connected together to create the storage and detain the water up to the 100 year flood event and release it slowly at the normal runoff rate. It will be released into the existing stormwater sewer line that is already under the parking lot and then into the ditch along River Street. Newton added the goal of the detention system, and the way the requirements are set up, is to prevent any additional water onto neighboring properties. Theobald asked about the maintenance for the underground storage and Newton explained that there is maintenance but the frequency of issues depends on the amount of trash (leaves or litter) that is caught in the system and how often it needs to be cleaned out. It can be cleaned out by a large vacuum. Duane Van Hemert (Iowa City Community School District Facilities Director) stated that this underground storage would have happened whether the addition was on the north side or east side so they could protect the playground area and not use it as a water detention area. Hensch asked if all the soil that will be excavated will be retained onsite or removed. Newton replied that the soil will not be able to be retained onsite and will have to leave the site. Hensch closed the public hearing. Theobald moved to recommend approval of REZ17-000016, a Sensitive Areas Development Plan subject to the following conditions: Substantial compliance with the development plan submitted. Establish easements for the stormwater management area. Establish any easements not currently existing for storm sewer and sanitary sewer. Certification by a licensed structural engineer will be required at the time of building permit application to ensure the stability of the building. To ensure there is a diversity of trees used and reviewed by the City Forrester. Parsons seconded the motion. Planning and Zoning Commission December 7, 2017- Formal Meeting Page 5 of 6 Parsons noted this has been a history lesson tonight learning there has already been five additions on Lincoln Elementary and commented that the proposal is a unique design and having this school means a lot to the Manville Heights area and is happy to see the School District investing in this school. Signs noted that he is familiar with the site and always thought it was a disturbed slope due to all the activity around the area. Martin noted that this area is special and to be able to add onto the school and maintain the flat surface areas for children to play is essential. Dyer agreed this is a good project and happy to see Lincoln Elementary preserved. A vote was taken and the motion passed 6-0. CONSIDERATION OF MEETING MINUTES: NOVEMBER 2. 2017 Parsons moved to approve the meeting minutes of November 2, 2017 with edits. Martin seconded the motion. A vote was taken and the motion passed 6-0 PLANNING AND ZONING INFORMATION: Martin noted she would not be present at the December 21 or January 4 meetings Theobald asked if the Commission can have a discussion about street lights at some point, there have been several complaints and in the news recently it has been stated that the LED lights are actually not obtaining the savings of energy that was projected and do cause a lot of light pollution. Hektoen stated that if Commission members wished they could send some correspondence to Council regarding the issue however it is not really in the prevue of Planning & Zoning agenda items. Miklo acknowledged a flyer in the Commissioner's packets where there are encouraged to attend a training session. ADJOURNMENT: Parsons moved to adjourn. Martin seconded. A vote was taken and motion carried 6-0.

We apologize that neither of us could come to speak to the Commission in person, but our son (a Lincoln Fifth Grader) has his first elementary band concert at City High tomorrow night. We own and occupy the residence at 911 Rider Street, which is essentially across the street from the southeast corner of the school district's property. We are very supportive of the proposed rezoning, and anything the City can do to facilitate the completion of the Lincoln Elementary renovation and addition. It is hard to overstate just how much Lincoln Elementary means to our neighborhood. Suffice it to say, however, that we believe that anything that helps Lincoln remain viable as a school building, which the proposed addition certainly does, will help keep our neighborhood stable and be a benefit to the City of Iowa City as a whole. We also note, as long-time residents of the neighborhood, that we really do not see the loss of the "protected slope" in question, as much of a loss. That portion of the hill is not something we have seen utilized by students in any manner.

Prepared By: Scott Sovers — Sr. Civil Engineer Reviewed By: Jason Havel — City Engineer, Ron Knoche — Public Works Director, Geoff Fruin — City Manager Fiscal Impact: $562,000, available in the Douglass St./Douglass Ct. Water Main Replacement account #W3223. Recommendations: Staff: Approval Commission: N/A Attachments: Resolution Executive Summary: This agenda item begins the bidding process for the Douglass Street and Douglass Court Water Main Improvements Project. This project generally includes the replacement of approximately 2,000 feet of water main, new domestic water services, driveway replacements as needed to install the water main and final surface restoration. Background / Analysis: The existing 6 -inch ductile iron water main along Douglass Street and Douglass Court has reached the end of its service life. As a result, there have been approximately 15 water main breaks since 1992. In order to reduce the inconvenience residents experience during breaks, and to decrease water fund expenditures resulting from frequent repairs, the existing water main was identified for replacement. Given the impact and disruption that the proposed water main replacement would have on residents, in addition to the City's accessibility goals, the installation of sidewalks on both sides of Douglass Street and Douglass Court were originally included 'in the project. Upon receipt of questions, comments and concerns from residents and property owners regarding sidewalk installation, City staff developed options that minimized private property impacts by reducing the sidewalk width and adjusting the alignment of the proposed sidewalk to preserve as much of the mature tree canopy as possible. Two options, including the installation of sidewalk on one side of Douglass Street and Douglass Court or the elimination of sidewalk on both Douglass Street and Douglass Court, were presented to Council at the December 6, 2016 council meeting. At this meeting, Council directed staff to eliminate sidewalks on Douglass Street and Douglass Court from the project. The plans, specifications, form of contract, and estimate of cost for construction of the Douglass Street and Douglass Court Water Main Improvements Project have been filed in the Office of the City Clerk for public examination. The estimated cost of construction is $562,000, and the project is expected to be completed in the fall of 2018.
