STAFF REPORT To: Planning and Zoning Commission Item: REZ22-0010 518 Bowery St Prepared by: Emani Brinkman, Planning Intern Date: August 3, 2022 GENERAL INFORMATION: Applicant: Connor Moellenbeck Daydrink Coffee connor@daydrink.coffee Contact Person: See above. Owner: M&W Properties Ryan Wade ryanwade1000@gmail.com Requested Action: Rezone from High Density Multi-Family Residential with a Historic District Overlay (OHD/RM-44) Zone to Neighborhood Commercial with a Historic District Overlay (OHD/CN- 1) Zone Purpose: To allow for a coffee shop on the property Location: 518 Bowery Street Location Map: Size: 1,470 Square Feet Existing Land Use and Zoning: High Density Multi-Family Residential with a Historic District Overlay (OHD/RM- 44), Commercial building 2 Surrounding Land Use and Zoning: North: Residential (RM-44) South: Residential (RM-44) East: Residential (RM-44) West: Residential (RM-44) Comprehensive Plan: 25+ DU/A District Plan: Central Neighborhood Open Space District: C3 Public Meeting Notification: Properties within 500’ of the subject property received notification of the Planning and Zoning Commission public meeting. A rezoning sign was posted on the site July 5, 2022. File Date: July 5, 2022 45 Day Limitation Period: August 19, 2022 BACKGROUND INFORMATION: The applicant, Connor Moellenbeck, is seeking a rezoning from High Density Multi-Family Residential with a Historic District Overlay (OHD/RM-44) to Neighborhood Commercial with a Historic District Overlay (OHD/CN-1) for a 1,470 square foot property located at 518 Bowery Street. The applicant intends to open a coffee shop at the subject property. The subject property contains a one and a half story building with a one-story addition. The building was originally constructed sometime between 1856-1864 as a grocery store by John M. Haas. Having been established as a commercial business prior to the adoption of a zoning code by the City in the mid-1920s, the property has continued to be used for non- residential purposes on the ground floor throughout its existence. The existing 720 square- foot building was originally used as a grocery store, and historic records show continued use as a grocery store from 1895 until the early 1970s when it served as the first home of the New Pioneer Cooperative Society. A retail establishment, the House of Jade, moved in when the New Pioneer moved out in 1975. Records show a brief tenancy by Helen Caldicott Community School in 1983. More recently the building was used by Zaza’s Pasta and then as an office. In 2012, the property was designated a Local Historic Landmark. The historic designation protects the building from demolition as well as exterior modification that would diminish its historic integrity. The designation also makes the property eligible for certain exceptions 3 and zoning waivers to allow the continued use of the property. In 2012 the property was granted a special exception to allow for sales-oriented retail use and then in 2016 was granted a special exception for general office and commercial retail (EXC12-000010 and EXC16-00010). These special exceptions allowed the continuance of commercial uses within a residential zone. Since the building has remained vacant for over a year, the property has lost its non-conforming use status and cannot receive a special exception for a different non-conforming use. In 2013 there was another special exception application submitted to convert the sales-oriented retail use to a coffee shop, the application was ultimately withdrawn. Given the size of the property and structure, it is not possible for the property to be re-adapted for a multi-family use and single-family residential is not allowed within the zoning district. The applicant wishes to establish another Daydrink coffee shop location at the property. Their mission is to provide high quality coffee while preventing continued adoption of “single-use” plastic. Daydrink only use glass jars for to-go containers with the hope of creating a more sustainable focused community. The applicant held a good neighbor meeting on July 27, 2022, but no one from the public attended. ANALYSIS: Current Zoning: The property is currently zoned as High-Density Multi-Family Residential with a Historic Preservation Overlay (OHD/RM-44). RM-44 zoning provides areas for development of high-density, multi-family dwellings and group living quarters but does not allow single-family or duplex dwellings. The zone allows, as a provisional use, hospitality-oriented retail (hotels, guest houses, meeting or event facilities), but does not allow any other retail or commercial uses. Through a special exception, community service uses are allowed. The purpose of High-Density Multi-Family Residential is for high-density multi-family housing located in proximity to downtown, the University, or other employment centers. The minimum lot requirement for a non-residential use in RM- 44 zoning is 5,000 square feet; minimum frontage is 35 feet; front setback is 20 feet; the required side setback is 10 feet. The property does not meet any of these minimum dimensional standards. The property does meet the rear 20 feet setback standards. The property is a Local Historic Landmark and is listed in the National Register of Historic Places. Changes to the exterior of the building would require review by the Historic Preservation Commission. The Historic District Overlay will still apply if the underlying zone is changed to CN-1. Proposed Zoning: The purpose of the Neighborhood Commercial Zone (CN-1) is to promote small-scale retail sales and personal service uses in a neighborhood shopping area. The zoning encourages neighborhood shopping areas that are conveniently located and that primarily serve nearby residential neighborhoods and promote pedestrian- oriented development at an intensity level that is compatible with surrounding residential areas. Allowed uses are restricted in size to promote smaller, neighborhood-serving businesses and to limit adverse impacts on nearby residential areas. Unlike the RM-44 zone, the CN-1 zone does not have a minimum lot area requirement nor a minimum frontage requirement. The front setback requirement is 5’ and the side and rear 4 setbacks are 0’ unless the property abuts a non-residential zone, which is the case with the rear boundary of the subject property. Uses allowed in the CN-1 zone are outlined in Table 1. Table 1 – Uses Allowed in CN-1 Household living uses Group Households PR Multi-family dwellings PR Animal Related Commercial Use General PR Commercial Recreational Uses Indoor PR/S Eating or Drinking Establishments PR/S Office Use General PR Medical PR Quick Vehicle Servicing Uses S Retail Uses Alcohol sales-oriented retail PR Hospitality oriented retail PR Personal service oriented PR Sales oriented PR Basic utility uses PR/S Community Service Uses General community service S Daycare uses PR Educational facilities Specialized PR Parks and open space uses PR Utility-scale ground- mounted solar energy systems S Communication transmission facility uses PR/S P = Permitted; PR = Provisional; S = Special Exception Coffee shops are classified as Eating Establishments. Eating establishments are provisionally allowed in CN-1 if they meet certain standards (see 14-4B-4-B-10), such as a maximum occupancy load of 100, which can be increased through a special exception. Additionally, drive-throughs are prohibited. Given the proximity to adjacent residential uses, staff recommends a condition that commercial uses may not be open to the public between the hours of 10:00 p.m. and 7:00 a.m. This helps to ensure the commercial use of the property remains compatible with nearby residential properties and to minimize activities that may be injurious to the use and enjoyment of residential uses in the vicinity. A similar condition was also recommended for Deluxe Bakery’s rezoning (REZ17-0006). Parking: The property has two parking spots. Eating establishments require 1 space per 150 square feet or 1/3 the occupant load, whichever is less. Depending on the floorplan, which is yet to be determined, the proposed use could require 4 off-street 5 parking spaces. Staff has notified the applicant that the property is eligible for a parking reduction via special exception due to its local historic landmark status and one may be needed for the proposed coffee shop. On-street parking along the portion of Bowery Street is prohibited during daytime business hours. Additionally, there is a high demand for on-street parking in the surrounding neighborhoods. Rezoning Review Criteria: Staff uses the following two criteria in the review of rezoning: 1. Consistency with the comprehensive plan. 2. Compatibility with the existing neighborhood character. Compliance with Comprehensive Plan: The Future Land Use Map of the Comprehensive Plan identifies this property as appropriate for multi-family residential development at a density of 25+ dwelling units per acre. The Central District Plan Future Land Use Map has the subject property designated as High-Density Multi-Family Redevelopment. This land use category is targeted at the redevelopment of existing multi-family where living conditions are less than ideal due to a lack of adequate pedestrian amenities and little open space. The plan category notes that possible redevelopment scenarios will need to be assessed prior to redevelopment. Due to the subject property’s local landmark status, demolition of the building will not happen unless the building was structurally unsound. Although the proposed rezoning does not directly align with the land use policy direction outlined in the Comprehensive Plan and the Central District Plan, there are several goals and policies within the plans that support the rezoning. The Comprehensive Plan encourages sustainable and walkable neighborhoods and envisions neighborhood commercial uses as contributing to the quality of life within neighborhoods. The Plan states: Neighborhood commercial areas can provide a focal point and gathering place for a neighborhood. The businesses within a neighborhood commercial center should provide shopping opportunities within convenient walking distance for the residents in the immediate area. The design of the neighborhood commercial center should have a pedestrian orientation with the stores placed close to the street, but with sufficient open space to allow for outdoor cafes and patios or landscaping. Parking should be located to the rear and sides of stores with additional parking on the street (IC2030: Comprehensive Plan Update page 22). The Comprehensive Plan also has goals about establishing strategies to retain and encourage growth of existing locally owned businesses, and recognize that small, and independently owned, local businesses are integral to Iowa City’s ‘brand’ and sense of identity (IC2030: Comprehensive Plan Update page 32). Also, to promote economic growth, encourage a healthy mix of local businesses and support entrepreneurial activity. Allowing the rezoning of this property, allows for the city to create space for neighborhood commercial. Additionally, since this building is currently vacant, a rezoning can help with infill development which is another goal in the comprehensive plan (IC2030: Comprehensive Plan Update page 7). 6 The Central District Plan acknowledges several properties originally developed with buildings that served as neighborhood grocery stores and have remained, over time as non-conforming commercial uses. These include the Design Ranch Building on Dodge Street, the former Seaton’s Meat Market, Watt’s Grocery on Muscatine, and Deluxe Bakery on South Summit Street. This property is like the other properties in that it has historically been commercial in a residential zone. Keeping these buildings as their original type of use create neighborhood commercial areas that serve as the focal point of a neighborhood (Central District Plan page 3). Iowa City’s Historic Preservation Plan also has goals to protect historic resources through efficient legislation and regulatory measures (Goal 2). The Plan also recommends that the City adopt strategies to conserve historic neighborhoods which reflect their organic development, historical roles and traditions, modern needs, and economic health and stability (Goal 10). Compatibility with Existing Neighborhood Character: This building has operated with non-residential uses since the building was built. This property has contained a grocery store, retail businesses, and offices, all as non-conforming uses. Those previous uses were compatible with the surrounding neighborhood character. As noted by the Comprehensive Plan, neighborhood commercial contributes to the quality of life in the neighborhood. When the building was built over 150 years ago, it was deliberately built along a main thoroughfare near a high traffic area, to attract business (National Register of Historic Places nomination, page 11, 16, and 19). The building being in a high-density area allows for pedestrian traffic for people who live in the immediate area. Traffic Implications: Due to the size of the lot, the limited ability to provide off -street parking, and the small amount of street parking on the surrounding streets, these would be a deterrent to people driving to the site. Any business on this property will have to rely on customers coming on foot or bike from the surrounding neighborhood. The property is in an established, high-density neighborhood. The neighborhood has easy pedestrian and biking access and is close to the University and downtown. SUMMARY: In summary, Staff supports the rezoning of 518 Bowery Street from High Density Multi-Family Residential with a Historic District Overlay (OHD/RM-44) Zone to Neighborhood Commercial with a Historic District Overlay (OHD/CN-1) Zone. Both the Comprehensive Plan and the Central District Plan contain language about having commercial uses in neighborhoods to help strengthen the community and increase the diversity of neighborhoods. The Historic Preservation Plan contains goals to protect historic resources through regulatory measures and conserve historic neighborhoods. NEXT STEPS: Upon recommendation from the Planning and Zoning Commission, the rezoning will be considered by the City Council. STAFF RECOMMENDATION: Staff recommends that the application submitted by Connor Mollenbeck for a rezoning from High Density Multi-Family Residential with a Historic Preservation (OHD/RM-44) to Neighborhood Commercial with a Historic Preservation Overlay (OHD/CN-1) for a 1,470 7 square foot property located at 518 Bowery Street be approved, subject to the following conditions: 1.Any commercial use may not be open to the public between 10:00 p.m. and 7:00 a.m. ATTACHMENTS: 1.Location Map 2.Zoning Map 3.Aerial Photograph Approved by: _________________________________________________ Danielle Sitzman, AICP, Development Services Coordinator Department of Neighborhood and Development Services BOWERY STS VAN BUREN STS JOHNSON STREZ22-0010 518 Bowery Streetµ Prepared By: Emani Brinkman Date Prepared: July 2022 An application submitted by Connor Moellenbeck for approval of a rezoning of 1,470 square feet of 518 Bowery Street from High Density Multi-Family Residential Zone with a Historic District Overlay (OHD/RM-44) to Neighborhood Commercial Zone with a Historic District Overlay (OHD/CN-1). 0 0.01 0.020.01 Miles BOWERY STS VAN BUREN STS JOHNSON STRM44 REZ22-0010 518 Bowery Streetµ 0 0 00 Miles Prepared By: Emani Brinkman Date Prepared: July 2022 An application submitted by Connor Moellenbeck for approval of a rezoning of 1,470 square feet of 518 Bowery Street from High Density Multi-Family Residential Zone with a Historic District Overlay (OHD/RM-44) to Neighborhood Commercial Zone with a Historic District Overlay (OHD/CN-1).

A rezoning and a subdivision sign were posted on the site on Camp Cardinal Boulevard. File Date: April 19, 2022 45 Day Limitation Period: The applicant has waived the 45-day review period. BACKGROUND INFORMATION: The applicant, Navigate Homes, is requesting approval for the rezoning of 27.68 acres from Interim Development—Research Park (ID-RP) zone to Low Density Multi-Family Residential with a Planned Development Overlay (OPD/RM-12) and a preliminary plat for land located east of Camp Cardinal Blvd and west of Camp Cardinal Road. The Preliminary Plat, Planned Development Overlay, and Sensitive Areas Development Plan is provided in Attachment 3. The proposed development would allow for the development of 22 duplexes, 4 townhomes and 30 multi-family units. For renderings of the multi-family building see Attachment 4. The development proposes the extension of Deer Creek Road off Camp Cardinal Blvd through the parcel connecting to Camp Cardinal Road. The proposed preliminary plat for the development is a cul-de-sac - loop layout running north and south, lined by 22 duplexes. Following Deer Creek Road east toward Camp Cardinal Road, the proposal includes a 30-unit multi-family complex (13 two bedroom, 17 one-bedroom units) and 4 townhomes with additional duplexes on the south side of Deer Creek. The site contains regulated sensitive features including wetlands, woodlands, and slopes. The Preliminary Sensitive Areas Development Plan proposes impacts to wetlands and modifications to the 100’ wetland buffer requirement (14-5I-6), which requires a Level II Sensitive Areas Review. A Level II Sensitive Areas Review requires submission of a Sensitive Areas Development Plan 3 (SADP). Furthermore, a Level II sensitive areas review is considered a type of planned development and as such, must comply with the applicable approval criteria set forth in chapter 3, article A, "Planned Development Overlay Zone (OPD)". Good Neighbor Policy: The surrounding property owners have been notified of the proposed rezoning and preliminary plat. A virtual Good Neighbor meeting was scheduled and took place on February 1, 2022. A summary of the meeting is included in Attachment 5. ANALYSIS: Current zoning: The area is zoned as Interim Development—Research Park (ID-RP). This zone is intended for areas of managed growth in which agricultural and other nonurban uses of land may continue until the city is able to provide services and urban development can occur. The interim development zone is the default zoning district to which all undeveloped areas should be classified until city services are provided. Upon provision of city services, the City or the property owner may initiate rezoning to zones consistent with the comprehensive plan, as amended. Proposed zoning: The applicant is requesting to rezone the entire area (27.68 acres) to Low Density Multi-Family with a Planned Development Overlay (OPD/RM-12). The purpose of the Low- Density Multi-Family Residential Zone (RM-12) is to provide for the development of high density, single-family housing and low density, multi-family housing. In this case, a mix of multi-family housing units and duplex units provides a diverse variety of housing throughout the neighborhood, as intended by RM-12 zoning. Because of this mixture, attention to site and building design is important in this zone to ensure that these housing types are compatible with one another. Due to impacts to the sensitive areas, a Planned Development Overlay is required. The OPD process allows for a mixture of uses, provided that additional criteria in section 14-3A-4 and 14-3A-5 of the City Code are met. General Planned Development Approval Criteria: Applications for Planned Development Rezonings 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, relative amount of open space, traffic circulation and general layout. Density: The applicant is requesting a rezoning to an OPD/RM-12 zone, which allows for a density of 15 dwelling units per net acre of land area (total land minus public and private streets right-of- way). The proposed 30-unit complex, 4 townhomes, and 22 duplexes adds up to 78 total units across the 25.02 acres of net site area, which equals 3.1 dwelling units per acre. Land Uses Proposed: The applicant is proposing a mix of duplex and multi-family residential. There are currently two areas to the west zoned RM-12 and one area to the southeast. The property to the immediate west was rezoned to OPD/RM-12 in 2017 but remains undeveloped. The property to the northwest also has RM-12 zoning with townhomes constructed, as well as ongoing townhome development. Cardinal Villas Condominiums located southeast of the subject property is also zoned as OPD/RM-12 with two multi-family buildings on the property. The area to the north is zoned OPD/RS-8 and contains duplexes similar to those proposed. The addition of more duplexes and multi-family housing to the area will complement the existing, ongoing, and future development plans in the area. Mass, Scale, and General Layout: Due to the potential impacts of the sensitive areas, the development layout is more compact instead of spreading out over the property. The proposed duplexes are located on the western edge of the site off a cul-de-sac street to the north of Deer Creek Road and a loop street to the south of Deer Creek Road. Additional duplexes front Deer 4 Creek Road to the east along with the proposed 30-unit multi-family buildings and townhomes. The multifamily and townhomes cannot exceed 35 feet in height and have a footprint of 12,000 square feet and 3,660 square feet respectively. The OPD plan shows duplex footprints with the access to garages from the front façade. 14-3A- 4K-1c-(2) requires garages and off-street parking areas be located so that they do not dominate the streetscape. Alley or private rear lane access will be required, unless garages are recessed behind the front facade of the dwelling in a manner that allows the residential portion of the dwelling to predominate along the street. This standard will be reviewed at site plan and building permitting stage to ensure full compliance to the requirement. Open Space: The proposed development will need to comply with private open space standards, outlined in section 14-2B-4E of the City Code. For the 30-unit complex, the calculation comes out to be 430 square feet of private open space required (10 SF per bedroom, 43 total bedrooms in complex). The duplexes require a minimum of 300 SF per dwelling and the townhomes require minimum 150 SF of useable open space. The applicant is aware of these open space standards as they are listed on the preliminary plat. The OPD plans shows 10,000 square feet of on-site open space for the multi-family uses. Additionally, the preliminary plat includes two outlots totaling 16.76 acres that contain regulated sensitive areas that will be placed in conservation easement at final platting. Traffic Circulation: The proposed development will have access off of Camp Cardinal Blvd through an extension of Deer Creek Road. The extension of Deer Creek Road will provide access to the entire site and, until Camp Cardinal Rd and a proposed traffic circle at the intersection of Deer Creek Road and Camp Cardinal Road are constructed, Deer Creek Road will provide temporary access to Camp Cardinal Road. This will provide a secondary access, if needed. The subdivision code 15- 3-2K authorizes the City to request an applicant to contribute 50% of the reconstruction cost of bringing the segment of the subject street that abuts the subject property to city standards. As a condition to the rezoning, owner shall contribute 50% of the cost of upgrading Camp Cardinal Road to City standards prior to issuance of building permit. The infrastructure also requires traffic calming devices. The contribution shall include 50% of the cost of construction of the traffic circle at the intersection of Deer Creek Road and Camp Cardinal Road. 2. The development will not overburden existing streets and utilities. The property can be serviced by both sanitary sewer and water. Access to the site will be provided through the extension of Deer Creek Road, which will connect to both Camp Cardinal Blvd and Camp Cardinal Road. 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. The nearest neighbors to the north of the subject property are separated by a woodland preservation area and a stream corridor. The nearest neighbors to the east and southeast will also remain separated due to the preservation of woodlands. The proposed development does not adversely affect views, light and air, property values and privacy of neighboring properties any more than would a conventional development. 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 purpose of this Title, and with other building regulations. The proposed development is not seeking any waivers or variations from the underlying zoning requirements. Additionally, the proposed RM-12 zone allows the proposed mix of residential land 5 uses proposed. The proposed multi-family building, duplexes, and townhomes provide a range of housing options. When factoring in both the total building area occupied (approximately 2.27 acres or 98,800 SF) and the total area occupied by R.O.W. (2.61 acres), the total lot coverage is equal to approximately 15.5%. Meaning, approximately 84.5% of the net site area will remain free of buildings, parking, and vehicular maneuvering areas. The mix of housing, the extension of Deer Creek Road, and the preservation of sensitive features are in the public interest. Compliance with Comprehensive Plan: The area does not have a district plan hence, the proposed development is reviewed according to the IC2030 Comprehensive Plan. The Future Land Use Map of the IC2030 Comprehensive Plan identifies the subject property as appropriate for residential development at a density of 8-16 dwelling units per acre. As previously stated, the subject property proposes around 3.1 dwelling units per net acre. This density is actually below what is envisioned in the plan; however, the site is constrained due to the sensitive features. The IC2030 Comprehensive Plan encourages urban growth through compact and connected neighborhoods. The Preliminary Plat, Planned Development Overlay, and Sensitive Areas Development Plan demonstrates a commitment to these goals by providing wide interconnected sidewalks and a variety of housing types that as noted in the Comprehensive Plan, “Ensure a mix of housing types within each neighborhood to provide options for households of all types and people of all incomes”. The Comprehensive Plan is also aimed at encouraging pedestrian-oriented development and attractive and functional streetscapes that make it safe, convenient, and comfortable to walk. The applicant is showing sidewalks along both sides of Maclan Court and Dear Creek Road. The plan also shows a sidewalk along Maclan Loop and connected to the Deer Creek sidewalk on the subject property. The sidewalk along Deer Creek will connect to the existing sidewalk along Camp Cardinal Blvd. Although the comprehensive plan discourages cul-de-sacs and emphasizes stub streets for future connectivity, the proposed development is limited due to sensitive areas and existing neighborhood constraints. Specifically, due to the layout of the neighborhood to the north, which incorporates a loop street, connecting with that existing neighborhood is not possible. By proposing development on the most buildable portion of the property, and thereby preserving the natural areas of the property, the development aligns with the goals of the comprehensive plan. Subdivision Design: The proposed subdivision contains 23 residential lots and two outlots. Outlot A is noted on the preliminary plat as open space area to be maintained by the homeowner’s association. Outlot B will also contain open space to be maintained by the HOA, but it will also include a storm water management area. Additionally, the preliminary plat shows a conservation easement area that will ensure the preservation of sensitive resources. The subject plat proposes the designation of 2.61 acres of public right of way though the extension of Deer Creek Road. This also includes the construction of Maclan Court and Maclan Loop from Deer Creek Road. Maclan Court is proposed as a cul-de-sac lined by 12 duplexes. Maclan Loop is a loop street lined by another 7 duplexes proposed. East of these streets and along Deer Creek Road are the proposed 4 townhomes, housing complex, and the remaining 3 duplexes. According to section 15-3-2A-4 of the City Code, cul-de-sacs should be avoided unless it can be demonstrated that existing constraints prevent the extension of the street to access existing streets within or abutting the subdivision. Due to sensitive area constraints, as well as the northern neighborhoods providing no access point due to loop street systems, there is not an outlet for through street access. Because of these constraints on the property, the applicant proposes Maclan Court ending in a cul-de-sac. Staff supports the proposed cul-de-sac design since previous iterations with a loop street resulted in greater impact on sensitive features. 6 Environmentally Sensitive Areas: The subject property contains regulated wetlands, woodlands, and slopes. The applicant has submitted a Preliminary Sensitive Areas Development Plan as part of the OPD rezoning. Due to the proposed disturbance of wetlands and associated buffers, a Level II Sensitive Areas Review is required. Jurisdictional Wetlands – The City’s Sensitive Areas Ordinance requires a 100 ft. buffer to be maintained between a regulated wetland and any development activity (14-5I-6E-1). The Ordinance does allow for buffer averaging to be permitted where an increased buffer is deemed necessary or desirable to provide additional protection to one area of a wetland for aesthetic or environmental reasons. The applicant has chosen to request buffer averaging, as wetlands and wetland buffers are proposed to be impacted. As required by 14-5I-6E-2, no buffer will be reduced by more than 50% and all provided buffers will be equal to or greater than what is reduced. Additionally, the applicant proposes a buffer reduction for the wetland located at the southeastern corner of the subject property. According to 14-5I-6E-3b of the City Code, a wetland buffer may be reduced by up to 50’ if the standards of the of the previously mentioned section are met, as demonstrated by a wetland specialist. A wetland specialist has determined that all standards of 14-5I-6E-2 and 14-5I-6E-3b are met. Staff finds that the proposed buffer averaging, and buffer reduction can be justified as demonstrated by a wetland specialist and will meet the requirements of the City Code. The existing wetland is comprised of approximately 0.90 acres. Approximately 14% of the existing wetlands will be disturbed or 0.059 acres to accommodate leveling of some lots and stormwater management. Per 14-5I-6G, staff has required the applicant to provide mitigation for the proposed disturbance to the existing wetland. Compensatory mitigation for the impacts to a 0.015-acre forested wetland will be provided at a ratio of 1:2. Compensatory mitigation for the southern wetland areas will be provided at a ratio of 1:1.5. The applicant has proposed to meet the City’s wetland mitigation requirements by providing onsite wetland mitigation. Specifically, the applicant will provide 0.096 acres of wetland to mitigate the loss of 0.059 acres of wetlands. Woodlands – As shown in Table 2, the subject property has approximately 22.9 acres of woodlands. The preliminary SADP shows that the development proposes to disturb 9.35 acres (55.8%) of woodlands on the subject property. An additional 3.43 acres will remain unimpacted but located within the 50’ woodland buffer area. The disturbed woodlands and buffer area total 12.78 acres (55.8%), leaving roughly 44.2% (10.12 acres) unimpacted which is above the 20% woodland retention allowed per the sensitive areas ordinance. Table 2 – Summary of Woodlands Existing Disturbed & Buffer Area Woodlands Preserved 22.9 acres 100% 12.78AC (55.8%) 10.12AC (44.2%) Steep, Critical, and Protected Slopes – The subject property contains critical and protected slopes. The impacts to these slopes are outlined in Table 3. Approximately 19.3% of critical slopes are proposed to be impacted, which is below the 35% of critical slopes that are allowed to be impacted per the sensitive areas ordinance. The sensitive areas ordinance only allows impacts to protected slopes if they are manmade or needed for necessary infrastructure through a Level II sensitive areas review. The approximately 10.3% of protected slopes that will be impacted are either manmade slopes or for the construction of the storm water basin. Table 3 – Summary of Regulated Slopes Slopes Existing Impacted % Non-impacted (%) Critical 328,991(100%) 63,473 (19.3%) 276,327 (84.1%) Protected 55,031(100%) 5,575 (10.3%) (manmade) 49,456 (89.7%) 7 Archaeological Sites – Staff reached out to the State archaeologist and inquired about needing an archaeological study for the site. Staff was informed that a study was conducted in 2004 and there are no current concerns with the site. Neighborhood Open Space: According to section 14-5K of the City code, dedication of public open space or fee in lieu of land dedication is addressed at the time of final platting for residential subdivisions. Based on the 27.68 acres of RM-12 zoning, the developer would be required to dedicate 1.87 acres to the City or pay a fee in-lieu of land dedication. Storm Water Management: All storm water management requirements for this site are being met in the existing regional retention basin located on the west side of Camp Cardinal Blvd and the proposed stormwater detention basin in Outlot B. Public Works staff have reviewed and approved the preliminary storm water management plans. Additional review will occur at the time of final platting. Sanitary Sewer Service: The development is serviced by a previously approved sanitary sewer plan of improvements that was originally proposed for development on the west side of Camp Cardinal Blvd. The proposed sanitary sewer line is located at the north end of the subject property. Correspondence: Staff has received public correspondence (Attachment 6) from neighboring residents voicing both concern and support for the proposed development. Generally, the concerns expressed relate to traffic and impacts on property values. NEXT STEPS: Upon recommendation from the Planning and Zoning Commission, a public hearing will be scheduled for consideration by the City Council. STAFF RECOMMENDATIONS: Staff recommends approval of REZ22-0001, a proposal to rezone approximately 27.68 acres of land located east of Camp Cardinal Blvd and west of Camp Cardinal Road from Interim Development – Research Park (ID-RP) zone to Low Density Multifamily Residential with a Planned Development Overlay (OPD/RM-12) zone subject to the following condition: 1. Prior to issuance of building permit, Owner shall contribute 50% of the cost of upgrading Camp Cardinal Road to City standards. This contribution shall include 50% of the cost of construction of the traffic circle at the intersection of Deer Creek Road and Camp Cardinal Road. Staff also recommends approval of SUB22-0001, a preliminary plat for Cardinal Heights. ATTACHMENTS: 1. Aerial Location Map 2. Zoning Map 3.

Joe Hughes - Navigate; Jason Walton - Navigate Brian Vogel -Hall and Hall; Susan Forinash -HHE Anne Russet - Senior Planner 7 X Neighbors were not particularly excited about potentially losing some privacy and seeing the private woodland area behind their home being disturbed. Applicant explained the closest proposed home will be approximately 400' from any existing home and will be buffered by existing woodlands and drainage way. The proposed development will be at an elevation of at least 50' higher than the existing homes. Old trees were cut down but never removed from previous work that started but was never completed.

I received notification of the rezoning request for IC Grove East and while I am generally in favor of the request, I do have some comments; It appears that Deer Creek Road will be stubbed to Camp Cardinal Road with the intention of later adding a traffic circle. If this connection is to provide 2ndary egress, it would be potentially putting an increased amount of traffic on a section of gravel road from the intersection southward to Gathering Place Lane. This section of road has been the source of erosion in the form of gravel washing down into the intersection of Camp Cardinal Road and Gathering Place Ln. The increase in traffic on the gravel portion will create more dust and the intersection of Camp Cardinal Road and Camp Cardinal Blvd is already a dangerous place to pull out of due to the reduced visibility on the curve and the high speed of traffic (well above posted limit) on Camp Cardinal Blvd. Perhaps a signal at that intersection would help. All that being said, I like the project and I believe it will add synergy to the area.

MINUTES PRELIMINARY PLANNING AND ZONING COMMISSION JULY 6, 2022 – 6:00 PM – FORMAL MEETING EMMA J. HARVAT HALL, CITY HALL MEMBERS PRESENT: Susan Craig, Maggie Elliott, Mike Hensch, Maria Padron, Mark Signs, Billie Townsend MEMBERS ABSENT: Mark Nolte STAFF PRESENT: Sarah Hektoen, Anne Russett, Parker Walsh OTHERS PRESENT: Mike Welch, Heather Robb, Joe Clark, Lawrence Luebbert, Rex Clemmensen, Jo Scott RECOMMENDATIONS TO COUNCIL: By a vote of 6-0 the Commission recommends approval of REZ22-0008, a proposal to rezone approximately 64.36 acres of land located north of Rochester Avenue and west of North Scott Boulevard from Interim Development Single-Family Residential to Low Density Single-Family Residential with a Planned Development Overlay (OPD/RS-5) and 0.31 acres to OPD/ID-RS zone subject to the following conditions: 1. Prior to issuance of building permit, Owner shall: • Dedicate an access easement agreement to allow access to Lot 66 as shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Dedicate a public access easement agreement to allow a public trail from the proposed development to Calder Park as shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Install the 10’ wide trail connection shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Dedicate to the City, with no compensation to Owner, additional right-of-way along Rochester Ave and N. Scott Blvd, the area of which shall be determined by the City Engineer in a form approved by the City Attorney. 2. The final plat for any of the above-described land shall incorporate traffic calming devices in locations approved by and designed to the satisfaction of the City Engineer CALL TO ORDER: Hensch called the meeting to order at 6:00 PM. ELECTION OF OFFICERS: Item moved to end of agenda. PUBLIC DISCUSSION OF ANY ITEM NOT ON THE AGENDA: None. Planning and Zoning Commission July 6, 2022 Page 2 of 15 CASE NO. REZ22-0008: Location: Northwest corner of N. Scott Blvd. & Rochester Ave. An application for a rezoning of approximately 64.37 acres of land from Interim Development Single-Family (ID-RS) to Low Density Single-Family with a Planned Development Overlay (OPD/RS-5) and approximately 0.31 acres of land to Interim Development Single-Family with a Planned Development Overlay (OPD/ID-RS). Craig disclosed she saw this on the agenda and contacted Hektoen to see if there would have a conflict of interest as she had heard that Vintage was building a senior living complex on the corner of Scott and Rochester, which isn't too far from where she lives and she contacted them because she has some interest in that model of senior living. Hektoen stated she thought there would not be a conflict of interest as long Craig could be impartial, which she can be and no contract has been executed. Walsh began the staff report with an aerial map of the property for the proposed development. He next showed the zoning map as well as how it fits in with the surrounding area. The current zoning is interim development single family, which is typically used for plant-related agriculture, provisional detached single-family homes and also used to post development for a property until a preferred use can be developed. The proposed zoning is 64.37 acres to low density single family residential (RS-5) zone, which is intended to provide housing opportunities for individual households. The zone allows larger lot sizes and setbacks creating neighborhoods with a limited density. While the proposed development contains duplexes and a multi-family building, the Planned Development Overlay (OPD) process allows for a mixture of uses in the RS-5 zone. 0.31 acres will be rezoned to interim development single family with a planned development overlay to accommodate an existing cell tower that is allowed by right through a special exception in 2009. Walsh showed the current existing uses on site which is lot 67 (3106 Rochester Ave) and lot 66 which is the cell tower. Recommended condition includes the dedication of an access easement to allow continued access to lot 66. The preliminary OPD and Sensitive Areas Development Plan proposes 65 single family lots and a private senior living community with an additional 12 single family units, three duplexes and 29 multifamily units. A private senior community clubhouse is also proposed. Walsh next went over the planned development approval criteria and how the proposed development fits in with the policy vision of the City. The first approval criteria is the density and design compatible with adjacent development. Starting with density, five dwelling units per acre are allowed in the OPD/RS-5 zone. Currently there are proposed 112 dwellings which includes the existing property and that comes out to be 1.94 dwelling units per acre. The land uses proposed include single family, two-family and multifamily, the extension of the existing single family development pattern in the area and concentrating more intense zoning on the corners. The applicant requested a waiver from 60-foot minimum lot with standard four units within the senior living community. The proposed modification will not result in increased traffic congestion, garages and off-street parking will be recessed ensuring garages do not dominate the streetscape. The applicant also requested a waiver from the duplex corner lot standard. If waived, duplexes must vary in design to prevent monotony. Staff finds that the approval criteria is met. Walsh showed some renderings for the options residents will have to choose from for the single-family (patio homes) and duplexes. The multifamily unit would be facing the private drive Planning and Zoning Commission July 6, 2022 Page 3 of 15 with the rear at the intersection of Rochester and Scott with the west side visible from Heron Drive. Regarding the requirement of open space, the applicant proposes 15,400 square feet of private open space for the senior living community which exceeds the required 540. It proposes providing 840 square feet for each single-family home and 600 square feet for each twin home. Staff recommends the dedication of an access easement and construction of a 10-foot-wide trail to Calder Park as a condition of the rezoning. With regards to traffic circulation, Walsh noted the development will include the construction of Allison Way, Heron Drive and private drive for the senior living community. The development will be accessed off Rochester Drive so there'll be no Scott Boulevard access. Proposed traffic calming features include two raised pedestrian crossings and a roundabout. A rezoning condition includes staff recommendation that at the time of platting traffic calming features be incorporated in locations approved by the City Engineer. Next approval criteria is the development will not overburden existing streets and utilities. The subject property can be serviced by both sanitary sewer and water and have sufficient capacity to accommodate the proposed development. Transportation staff requested a traffic study which found 823 new daily trips with full development and occupancy which is estimated to be in 2026. The study found that traffic at peak hour level of service would operate at an acceptable level-of- service or a better rating. The study determined that development would not overburden existing streets and staff concurs. Staff does recommend a condition of the rezoning to include dedication of public right-of-way at the intersection of Rochester Avenue and North Scott Boulevard for potential future improvements that may include a roundabout. Recently receiving new information from Public Works, the applicant submitted a concept which would require a setback modification from 40 feet to 30 feet along portions of Rochester and staff finds that the approval criteria in 14-3A-4K-1A to be met. Moving onto approval criteria three, development will not adversely affect views, property values and privacy. Walsh stated the proposed development continues the single-family development pattern that exists south of Rochester Avenue and concentrates more intense uses at the intersection of two arterial roads and includes three outlots of approximately 33 acres to be placed in conservation easements. The closest neighbors will be to the south and to the west. To the west is Larch Lane which would be separated by approximately 18 acres (outlot A) and to the south it will be separated by Rochester Avenue so staff finds of this development will not impact existing residents more than a conventional development. Next is the approval criteria for land use and the building types will be in the public interest. The proposal incorporates single-family, two-family and multifamily uses, provides diversity of housing and helps satisfy an ongoing need of senior housing. Outlots A, B and C make up roughly 33 acres or 50% of the land area and will remain undeveloped. The proposed development balances environmental protection with the need for increased housing. Regarding consistency with the Comprehensive Plan, the Comprehensive Plan identifies this area as conservation design and encourages the preservation of sensitive areas by guiding development away from sensitive areas. Conservation design is appropriate in areas with Planning and Zoning Commission July 6, 2022 Page 4 of 15 sensitive features this development has an interconnected system with open space, wide sidewalks and trails to connect the community. Looking at the North District Plan, the North District Plan future land use map shows a vision of single family residential, townhomes, and small apartment buildings. The Plan encourages cul-de-sacs when appropriate, encourages more intense housing near arterial roads and envisions an extension of Amherst Drive across Ralston Creek. However, due to the fact that land uses have changed since the adoption of Northeast District Plan, specifically with the creation of Harvest Reserve, staff is not recommending a stub street to the north that would eventually tie into Tamarack Trail. The Northeast District Plan calls for trail connections along waterways, around ponds and through parks to encourage trail connection at the end of cul-de-sacs. The Plan shows connections between major destinations and strongly encourages a trail system to connect neighborhoods with open space, a connection between Bluffwood and Hickory Hill Park, a connection between Hickory Hill Park and the neighboring park, which is now called Calder Park. To support this policy direction, staff has requested a 10-foot wide trail between the proposed development to the edge of Calder Park. The development will also include the construction of a 5-foot wide sidewalk along Rochester Ave, a current gap in the City’s sidewalk network. Regarding compatibility with existing neighborhood, the proposed development is generally consistent with the existing neighborhood character, the development would provide a continuation of single family from south to north across Rochester Avenue, the proposal locates high density units in the southeast corner, providing a transition of uses from single family to multifamily and then to Old Towne Village directly southwest of the property. Larch Lane to the west contains attached single-family units and as mentioned earlier, they'll have an approximate 18-acre natural buffer which will separate it from development. Regarding sensitive areas, a review of sensitive areas by the Commission and City Council is required due to the impacts to wetlands, modification to buffers, and impacts of more than 35% on critical slopes. Looking at wetlands, the sensitive area ordinance requires 100-foot buffer between wetlands and development. Wetland buffer averaging may be permitted when necessary and is justified by wetland specialist. Wetland buffer reduction may also be used when necessary as justified by wetland specialists and the reduction proposed is only for the southwest corner wetland to accommodate the installation of a sidewalk. The existing wetlands are approximately 3.03 acres with 0.43 proposed to be disturbed. Mitigation requires replacement ratio of one to one which will be accomplished through offsite wetland bank credits. Regarding critical and protected slopes, 9.3 acres are critical slopes and 4.7 are proposed to be disturbed or 51%. The subject property contains no protected slopes. There are 40.3 acres of woodlands with 14 acres proposed to be impacted or 34.7%. Woodland buffers proposed to be impacted are 6.1 acres or 15.2%. Woodlands preserved will be 20.2 acres or 50.1%. Regarding archaeological sites, Walsh stated the Phase One archaeological survey of the subject property noted that the subject property is not eligible for listing in the National Register of Historic Places. No further archaeological work is recommended for the site. Finally, regarding neighborhood open space, according to section 14-5k of the City code, dedication of public open space or fee in lieu of land dedication is addressed at the time of final platting for residential subdivisions. Based on 64.37 acres and a RS-5 zone the developer would Planning and Zoning Commission July 6, 2022 Page 5 of 15 be required to dedicate 1.38 acres or pay a fee in lieu of land dedication. The applicant has requested a fee in lieu of land dedication. Staff has received correspondence regarding this item in the form of emails from neighboring residents. Concerns expressed include single family units one through six along Rochester Avenue, which have since been removed by the applicant, traffic and removal of woodlands. Staff recommends approval of REZ22-0008, a proposal to rezone approximately 64.36 acres of land located north of Rochester Avenue and west of North Scott Boulevard from Interim Development Single-Family Residential to Low Density Single-Family Residential with a Planned Development Overlay (OPD/RS-5) and 0.31 acres to OPD/ID-RS zone subject to the following conditions: 1. Prior to issuance of building permit, Owner shall: • Dedicate an access easement agreement to allow access to Lot 66 as shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Dedicate a public access easement agreement to allow a public trail from the proposed development to Calder Park as shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Install the 10’ wide trail connection shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Dedicate to the City, with no compensation to Owner, additional right-of-way along Rochester Ave and N. Scott Blvd, the area of which shall be determined by the City Engineer in a form approved by the City Attorney. 2. The final plat for any of the above-described land shall incorporate traffic calming devices in locations approved by and designed to the satisfaction of the City Engineer Next steps would include upon recommendation from the Planning and Zoning Commission, a public hearing will be scheduled for consideration by City Council. The anticipated timeline would be at the July 12, 2022 meeting Council votes to hold a public hearing and at the August 2, 2022 meeting Council there is a public hearing and first consideration. Hensch has a question regarding the request for the waiver to decrease width of the residential lots to less than 60 feet, was there a reason for that other than just to put more lots in there. Walsh stated the reason was when they had the applicant put in the imaginary lot lines, it showed that the units they had proposed would not be able to accommodate a 60 foot lot width and so to make sure that they could fit the units proposed, they requested a waiver which will require the garage setback and they later submitted floor plans which showed all of the garages would be recessed. Hensch also asked about woodlands, with 49.9% of the woodlands being disturbed does any of the development ordinances address replacement of woodlands. Russett replied there is a mitigation requirement if the impact is above 50% but since they’re below that threshold, there is no mitigation required for the woodlands. Townsend asked if any of these new units being developed are considered affordable housing. Planning and Zoning Commission July 6, 2022 Page 6 of 15 Hektoenn stated nothing is obligating them to provide affordable housing, whether they choose to or not, it's up to them, but it's not part of this process. Padron asked why a change was made on the corner. Walsh explained that would be to accommodate the requested additional right-of-way for a potential future roundabout. After Public Works contacted the applicant they noticed that the 40-foot setback would not be met along the entirety of that right-of-way, which is the need for the requested modification. Russett added that request that was not included in the agenda packet as it was a new request that came up on Friday after the packet was published and the Public Works staff had provided a sketch of the amount of right-of-way they needed for the roundabout. Craig had a question about the trail to the park, which is quite long and goes over water and it goes through the Harvest Preserve area, which is her understanding is private land and the public don't have access to Harvest Preserve, so how's that going to work. Walsh deferred to the applicant to answer that question. Hektoen noted there's a conservation easement that is necessitated by the mitigation activity that was required, so the public will be able to walk on that trail even if the trail will still be on private land. Craig understands why it's preferred that both the entrance/exit options are coming from Rochester, but to not even have a pedestrian option over to Scott Boulevard seems less than ideal. Russett noted staff did have conversations about access but noted it's really hard with the environmental resources on this site, and Harvest Preserve to the north, to have an interconnected street network. There's also an existing conservation easement in outlot A, that restricts any street network to the west. A very small portion of the development actually fronts Scott Boulevard so providing access to Scott Boulevard would have required a change in the rezoning boundary, and it would have also impacted the wetland that's within outlot C. Craig noted there's a lot of jointly held land here, she assumes there's going to be a homeowner's association or something that has to take care of all those acres and it just concerns her when the next derecho comes through and half the trees are laying on the ground, who's going to take care of it or invasive species and all that. She feels the City needs to have something that addresses those things. Signs asked if the sidewalk that's existing on Scott Boulevard goes all the way from Rochester north or does it stop. Walsh confirmed it does go all the way. Signs asked about on Rochester along the southern border this property, is there an existing sidewalk. Russett confirmed one will be required as part of this project. Signs also asked to confirm the trail to Calder Park will include a public easement which will allow the public to go through the trail. Is that conservation easement already in existence. Walsh explained the outlots would be placed into conservation easements at final platting, which would restrict them from any future development. Craig and just wanted to reinforce her point, who's going to plow that trail in the wintertime. Russett replied the trail will be maintained by the City. Planning and Zoning Commission July 6, 2022 Page 7 of 15 Padron noted the proposed sidewalk on Rochester doesn’t look as wide as the sidewalk on Scott Boulevard, why aren’t’ the sidewalk going to be the same size. Russett is not actually sure, in certain instances the City requires wider sidewalks and they did with the development of Scott, but for Rochester, she doesn’t believe they would be requiring anything more than five feet. Hektoen added City policy is usually that one side of the street has the wider sidewalk. Hensch opened the public hearing. Mike Welch (Welch Design and Development) representing the developer, the developer, Joe Clark is here as well as Heather Ropp from Ewing Properties in case there are specific questions about Ewing properties on lot 65. Welch began by noting Walsh did a great job in the staff report hitting the high points, but Welch wanted to talk about the process they've gone through over the last few months with staff and then also with the Good Neighbor meeting they had. An important piece of this development and this project was the iterative nature, and they did a really good job of working through issues. As alluded to, they talked about the possibility for access off Scott Boulevard and looked at that both from a sensitive areas for topography and wetlands, and just from general logistics, and getting that connection proved to be exceedingly difficult with the street grades that they would have ended up with and they wouldn’t be code compliant with those and the landowner was interested in keeping the northeast corner of the development not developed. Another important point is their north boundary is the south boundary of Harvest Preserve and the land that they're developing is actually not owned by Harvest Preserve but it's owned by an entity called Monument Farms. So there are two separate entities in that conservation easement. The conservation easement does stop at that north boundary of the development and Harvest Preserve does own currently the piece of land in the northwest corner, but it's not part of their overall conservation area. Welch noted at the good neighbor meeting a lot of the public didn't understand that too, that there was a line where Harvest Preserve stops, and it doesn't continue all the way to Rochester Avenue. That took some people by surprise at that Good Neighbor meeting. Welch showed the Commission what they had presented at the Good Neighbor meeting. On the photo the white boxes are what they're showing as currently corresponding with the lots, they did have those six homes fronting on Rochester, they have been required to have rear access off the back and then a little narrower, smaller house, and they were bringing those in as a way to further increase that housing diversity in Iowa City and get a different price point house wise. At that meeting with the neighbors, which was really well attended (they had 24 homeowners sign in, which included husbands and wives or two people on the same address sign in) and a lot of good questions came from the neighbors. Welch noted the biggest takeaway they got was questions about traffic, questions about woodland impacted but the one that really stood out was the six lots on Rochester and what the impact would be for people who live south of Rochester and are used to looking at that wooded area which would now go away and they would see houses. Welch stated the development team regrouped after that meeting and looked at the feedback and felt like given that opposition and the concerns, they eliminated those six lots from the development. The other piece that came up in talking to staff and understanding it a little bit better is that existing conservation easement precludes any utilities from crossing it and any trail or any kind of access so that forced them to take and snake that trail around to the north and to do that they work closely with Harvest Preserve. It took a few Planning and Zoning Commission July 6, 2022 Page 8 of 15 days but they got an agreement in place to allow that pedestrian access across that piece of land to get that connection to Calder Park. Welch noted they're really excited about this project, not only is it good for the people who live over on the north side of Rochester, or Ralston Creek, as gives them a way to get to the south, but for the people who end up living in the development, whether they're in the single family homes, or in Ewing's parcel on the corner, to have access to a neighborhood park is a really nice benefit. It also provides a nice scenic trail that then follows Hickory Trail into Hickory Hill Park, just down the road. The other piece that they think is really good about that connection is an elementary school student who goes to Lemme has a way to connect through and cut through and walk to school. For those who aren't school age, but maybe want to go get a Dairy Queen, it takes three quarters a mile off the walk by going on the trail. As one of the neighbors said, now he can take his ebike to Blackstone so there's lots of benefits for all ages. Welch also wanted to highlight the scale of this development in the scale of the overall neighborhood. Their development is 65 acres, they're removing 14 acres of woodland, but there's 33 acres that's been set aside in those outlots which will be conserved forever. It was important to note the balance of development versus preserving what's there. This is essentially an infill development, taking that last piece that's available there, and making use of road and utility infrastructure that's there. The other piece important to highlight is outlot B is the only piece of this property that has mature trees on it. Looking at the aerial photos, going back to the 30s, this area was pasture. The archeological study shows that there were two farmsteads close to Rochester Avenue and if you go back through and poke around, you can find some of the remnants of those there. But most of this land was pasture at some point, other than the woods in outlot B and that's the original mature trees that are being preserved. Welch addressed the question about the trail and crossing Ralston Creek. He stated they will be doing the study as part of the planning process to determine if that's a bridge or a culvert and look at what they need to do. There'll be DNR and Corps of Engineer permitting required for that. Same with the wetland impacts that they do have, they've started that permitting process with the Core for those mitigation impacts, they're mitigating off site and that's the Corps of Engineers preferred method for that wetland mitigation, they will be taking advantage of the wetland banks that exist now in the Johnson County area. Hensch noted Welch said that on outlot B those trees existed pre-1930s aerial photographs and the remainder was all pastureland so that's just trees that have voluntarily grown up since that time since the pastures have been taken away. Welch confirmed that was correct and noted it’s actually pretty dramatic looking at the 90s and on. Hensch asked if they did a tree inventory. Welch stated as far as the woodland areas, they use the aerial mapping to determine those boundaries and a little bit of field survey. They did consult with Impact 7G on the wetlands and as part of that they did a threatened and endangered species analysis so they do have a little bit more information, and it's in their report as far as what species are in there. Speaking of trees, Hensch noticed one of the public comment comments was about having Bradford Pears in the planting schematics. He just wondered where they got that. Welch agreed, Planning and Zoning Commission July 6, 2022 Page 9 of 15 he’s not sure if those are in there, because typically the City Forester would not allow those to be in there and the City Forester has reviewed the landscape plan. Hensch noted Welch stated on the six houses that were originally proposed for Rochester he asked if they were going to have a different price point. Were those going to be more affordably priced. Welch stated just based on the lot size, because they were fronting Rochester and they can't get driveway access directly onto Rochester, they would have been rear loaded with a shared drive, allowed a smaller footprint house on those six lots. Hensch stated merely because this is an area that he finds very curious, the main concerns the adjacent property owners had was it would interfere with their view shed. Welch confirmed and added it was the impacts of those houses on their property values and their views. Heather Ropp (Regional Director for Ewing Properties) covers the eastern Iowa territory. She noted they currently have two communities complete in the Johnson County area and one under construction in North Liberty. What they are proposing here on the east side is 55 and above housing, it's an ownership model, so these aren't rentals and don't become Airbnb’s, these are owned and operated and controlled by the owners or the members that live there. They are shareholders buying a share into the entire property. They are going to have a mix of individual homes, patio homes (slab on grade homes), optional basements, universal design concepts, designed to age in place. They're also going to add a few duplexes in there, just so they can get some more density on the site again, universal design concept, duplexes, and then a two-story building which sits at the corner of Rochester and Scott. The units will be ranging in size from 1000 square feet up to potentially 1800 square feet. Again, the universal design concept designed to age in place with underground parking. The entire community will enjoy the common spaces that will be on the property, in the two-story building there will be a great room, there will be a workshop in the garage area, in the clubhouse a fitness center, an outdoor grilling area, meeting spaces, game rooms, and other activities to do. They are really promoting this as community and building beautiful places to live. Their mission is to provide a community where people know each other and they interact, it is known that as people get older sometimes they lose that social aspect of their life and they are here to bring that back to the people in the community. Hensch asked how many units they are hoping to build there. Ropp replied it’s 28 or 29 in the two-story building, 12 individual homes and then 6 homes in the duplexes. Hensch asked about the only 55 and over. Ropp replied the state of Iowa has a law that 20% of that population can be under the age of 55, but over the age of 18, but there are minimum income requirements to financially qualify to live in any of their communities. Craig had a question about parking noting the visitor parking for 37 units seems inadequate. Can people park on the street there. Ropp noted the two-story building will have heated underground parking so the people that are shareholders in the building will have a dedicated parking spot below and it should allow for a second car parking below. The garages will have attached two car garages and then they'll have some driveway access and then they usually try to allow for a common parking area near the clubhouse for visitors. She hasn’t really seen a parking plan yet to give any input on that. Planning and Zoning Commission July 6, 2022 Page 10 of 15 Craig noted if they got three book clubs meeting on the same night, they are in trouble. Welch noted the street is a 26 foot wide private drive so that's a typical city street and would allow for parking on one side. Signs asked if there is a pool in the clubhouse. Ropp said they are proposing an outdoor pool. Padron noted this is all independent living so people will be able to purchase the properties, so when someone passes away will the property go back to the company or can the family resell it. Ropp explained being in a senior housing cooperative the members are the shareholders so they're buying a share of the entire property. When somebody passes away, they can set it up however they want, they can set it into a trust and state a transfer on death. When that happens, it's the responsibility of the community manager to resell that person’s share and it goes back to the beneficiary named, but the transactions are all handled in house by the community manager on site. Padron asked then could someone younger come and stay or would it always have to be someone 55 and over. Ropp said visitors are definitely allowed and encouraged but to live there full time, residents have to be over the age of 18. This is a senior community with ownership 55 and above, but visitors that are staying with somebody for a long term have to be over the age of 18. Grandkids and guests can come visit, but to live there long-term they must be over age 18. Craig asked what the vision for the maintenance of all the woodlands is. Welch stated that would be monitored by the homeowner’s association with the typical language that invasive species removal can happen, dead trees can be taken down, and it can be used for recreational purposes, but someone can't come in and just start clearing or anything like that. Ropp added their community is maintenance free, the community manager and maintenance technician on site will be handling all the maintenance of the members living there, not only outside the home, but everything inside the home as well. Padron asked regarding the heating parking underneath the two-story building, will there be solar panels or EV charging station for cars or anything like that. Ropp said they will probably put in those things as requested. If some of the early people that purchase have an electric vehicle, they will work with them and plan on that. Since the garage in a co-op is a community space, they would have to figure out how to monitor or meter that outlet specifically for use of an electric car but it is definitely something they'll consider. In the individual homes and duplexes, that's something if people purchase early, they can build into the construction. Joe Clark (Developer) is also present to answer questions. Padron noted sometimes the trails can be very hidden and then people don't really know that they are there to use them. Are they planning on having a sign or something to identify the trails. Clark replied that's going to be on the City as to what sort of sign they want coming in. He thinks the City could probably put something over at Calder Park that says there's trails going back through there. They'll probably need to be a connection from Hickory and Tamarack that comes down through Calder Park so he’s guessing people will see the trail heading down through there. Planning and Zoning Commission July 6, 2022 Page 11 of 15 Lawrence Luebbert (3269 Rochester Avenue) has lived there for 22 years, the house he built was a parade home in 2000. Before he bought that lot, he researched the whole area about what was to go in there and it's been great because he’s had wildlife, too much wildlife actually, all these years. But he thinks this is a great plan and likes the idea. In terms of the trees and the land, there were cows across the street when he bought his house, it was all grassland and cow pasture. He was a little bit concerned about the small houses, he thought that was awful tight because of the terrain but that sounds like that's gone. He is also a fairly serious bicycle rider so the trail will be nice. It's just a really good layout for the area. Rex Clemmensen (15 Heron Circle) is a neighbor of Luebbert’s and also likes the development but has one concern and that is the corner where Heron runs into Rochester. Because Heron is a cul-de-sac that's the only way they can get out and he looked at the traffic study and it says it's going to be 831 more trips, about 300 more cars. Also it decided at that intersection the average wait time would increase by nine tenths of a second which he finds wildly implausible because all these cars that are going to be coming out on there and there's just a stop sign on either side. While he’s in favor of development, he would like to see on the senior center where the private drive is, it looks like there's a short shot out to Scott Boulevard. He understands why they can't do it in the far northeast but why not there where it would alleviate some of the congestion at that corner. The study may say that is not that busy of intersection, but it can be busy in the mornings and at night. If there is traffic on Rochester, those on Heron are going to wait some time to get on there and they have no other way to get out except there. So he’d suggest either doing a little blurb out of there to Rochester or at the minimum take Rochester Avenue to three lanes all the way back to Tetons Circle, so they can at least have a turn lane to get out of there. He’s afraid people are going to be waiting at that intersection all day. Luebbert noted he has a point, he’s complained to the city a number of times about Rochester strip after dark coming from that four way stop. He’s seen cars doing 50-60 miles an hour through there. Craig noted the City is reserving the option someday of putting a roundabout there and that might actually help that kind of thing. Jo Scott (608 Larch Lane) stated she doesn’t have any objection to the plan and thinks it looks really pretty good. She is glad that they took the six houses out, that would have been her objection because that would impact their area. The one thing that she thinks about when she looks at the number of homes in here is the traffic on Rochester, the speed limit right now is 35. She would hope that the City would change that speed limit to 25 as it is already hard for them to get out of their area, people do just come flying down Rochester. She hopes that if this development is approved, they will seriously consider lowering that speed limit to 25 with that much traffic that this would entail. Hensch noted unfortunately as much as they'd like to this Commission doesn’t have the authority to reduce speed limits but that is certainly something that they can address the City with and ask. Unfortunately, studies have shown that lowering the speed limit does not slow down traffic, it's other factors that actually slow down the traffic, not the speed limits. When this goes forward to the City Council, that would be a time to bring up the speed limits. Planning and Zoning Commission July 6, 2022 Page 12 of 15 Hensch closed the public hearing. Signs moved to recommend approval of REZ22-0008, a proposal to rezone approximately 64.37 acres of land located north of Rochester Avenue and west of North Scott Boulevard from Interim Development Single-Family Residential to Low Density Single-Family Residential with a Planned Development Overlay (OPD/RS-5) and 0.31 acres to OPD/ID-RS zone subject to the following conditions: 1. Prior to issuance of building permit, Owner shall: • Dedicate an access easement agreement to allow access to Lot 66 as shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Dedicate a public access easement agreement to allow a public trail from the proposed development to Calder Park as shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Install the 10’ wide trail connection shown on the Preliminary Planned Development and Sensitive Areas Development Plan. • Dedicate to the City, with no compensation to Owner, additional right-of-way along Rochester Ave and N. Scott Blvd, the area of which shall be determined by the City Engineer in a form approved by the City Attorney. 2. The final plat for any of the above-described land shall incorporate traffic calming devices in locations approved by and designed to the satisfaction of the City Engineer Townsend seconded the motion. Hensch noted when he saw this drawing, it reminded him of the development on Cherry Street, that new development going on Cherry between Pepper and Gilbert, it has multiple family, townhouses and a looped road with single family dwellings and that's progressing very nicely there. That pushed him to be predisposed to this because it reminded him so much of it. Additionally the neighbors’ concerns have largely been addressed, traffic is always an issue and that's why people need to be persistent, addressing the City Council. He will support this application. Signs wanted to commend everyone involved in this project, he doesn’t recall ever having seen a proposal that matched the Comprehensive Plan and the neighborhood plan vision so well. He commends them for doing this conservation design, preserving the sensitive areas and the woodlands and trying to maximize space and that's why he don't have a problem with smaller lots because that's the price to pay to get some more open space. He is very supportive of this project, he is always concerned about these outlots, because they always say the outlots are just going to be there and then five years later someone comes with a plan for the outlot. He doesn’t see anything in here that requires conservation easements but will trust that staff is going it taken care of along the way. He also noted this may be the first time they've had a development of this size where neighbors were all generally supportive of the project so that speaks a lot to the quality of it. Craig noted she is an eastsider and likes all this development on this side of town. The Planning and Zoning Commission July 6, 2022 Page 13 of 15 combination of senior living with the single-family housing is a good one. She wishes there was an affordable option but understands why it was taken out. She is in support of the plan. Padron agrees that she would like to have seen those six units that were going to be affordable to stay. Senior living is a big issue as big as affordable housing here in Iowa City, Oaknoll has a very long wait list, but thinks the affordable units should have stayed in in the project. Townsend noted it wasn't considered affordable housing, it was less pricey housing. So that is different from affordable. Padron agreed but noted they need affordability for different income levels. They have to remember that affordability is needed for all income levels, not only for lower income people. Townsend agreed it's great that there are some finally some 55 and over housing that isn't just dependent living because there are quite a few seniors that enjoy being able to do what they want to do and still have a place they can call their own. So this is a great project for the more mature adults. Padron had one more comment, that corner at Scott and Rochester can get very, very busy. Maybe the City can think about adding a light there or something because it's a four way stop sign and it can get really busy especially very early in the morning and at five. Adding more cars to the traffic is going to have an impact. Hensch agrees, four-way stops are so inefficient because everyone just sits there and looks at each other.
