3 DRAFT COPY 5. PZ Case No ; Residences at 62W PUD; The property owners at 6000, 6010, 6012 and 6016 NW 62 nd Avenue have requested a rezoning of their properties comprising approximately acres from RO Mixed Use Center to PUD allowing multifamily residential development up to a density of 26.5 units per acre. The subject properties are located south of NW 62 nd Avenue and west of NW 59 th Court. Aaron Wolfe presented the staff report. Petersma inquired about the density for the Winwood Apartments. Wolfe responded that it is zoned R-4, but does not know the specific density. Johnson inquired about the density of AHEPA. Wolfe responded that he does not know. Tom Ruprecht, R&R Realty, Jordan Creek Parkway, have met with neighbors and discussed details of the project, they will move the building as far north as possible and have agreed to install a fence. Johnson inquired if there are balconies proposed on the south face. Ruprecht commented that he cannot speak for exact design, there will be balconies but he does not know their location. Petersma opened the public hearing at 7:12 p.m. Troy Peterson, 6045 NW 61 st Avenue, stated that he is an adjacent neighbor to the south of the subject property. Peterson distributed copies of information. Peterson discussed the elevations and expressed concern about the height of the proposed building, with single family. Peterson commented that the proposed 4 th story is what is causing the need for higher density, all other apartments in the city are three stories or less. When approached, the developer advised that they would have to contact their investors out of state. When initially contacted, residents assumed that the proposed development would be comparable to the existing Winwood Apartments. There is a concern that residential owners are being encroached upon. Lisa Becton 6075 NW 61 st Ave, inquired about sewer and water capacity of the proposed units, if not sufficient who will pay for the improvements. Becton expressed concern about traffic, NW 62 nd Avenue is one lane each way currently, will it be able to handle the increased traffic and who would be responsible for road improvements if needed NW 61 st Ave, also a neighbor, stated that the biggest concern of neighbors was privacy, but Ruprecht cannot say whether there will be balconies overlooking the residential properties. Inquired how this building would not become an eyesore, are there other examples in the metro area that are not eyesores or detract from neighboring property values and fit with the neighborhood. Page 2 of 4

4 DRAFT COPY Tom Leffler, 5985 NW 61 st Avenue, biggest concern is the proposed height, he sympathizes with neighbors and can t see what kind of buffer would be adequate to screen a 4-story building from adjacent residential properties. In other areas the height may be appropriate but the surroundings should be considered. Leffler explained that has had no trouble with AHEPA property next to his property, but it is set further away from his property and is three stories. Commission needs to exercise discretion and determine if this proposal makes sense in this location. He is opposed to the rezoning request. Petersma closed the public hearing at 7:26 p.m. Wolfe explained that he has now looked into the AHEPA property and it is a total of 60 units, which is a density of units per acre. Height is a site plan issue, the height is allowed in the current zoning district and so the project could be built under the current zoning but still be able to be built to the same height. Wolfe noted that there is sufficient sewer and water capacity along NW 62 nd Avenue, if any improvements are needed in that regard the developer is required to address it. Access would be reviewed with the site plan. Rubrecht explained that his company owns the Winwood Apartments as well. They hired an architect and looked at developing an urban design, when the design was done it came out to 137 units, at lower density it becomes less feasible and it may be necessary to lose some of the aesthetic elements. Johnson inquired about what Rubrecht means by urban design. Rubrecht explained that elements include surface level parking with no ground level units, and street frontage close to the streets to give a streetscape appearance like one would see downtown. They are looking to market to young professionals. Severino asked if there was no change to the zoning, where are the 7 additional units that would be lost, would it they all come from the 4 th floor. Rubreck, would have to go back to drawing board and redesign to account for the lost units. Petersma inquired about the amount of concrete on the concept plan. Rubrecht answered that there is a parking requirement. Wolfe noted that one enclosed unit can be counted toward parking requirements, again this is something to be discussed at the site plan stage. Smith inquired about how the applicant will buffer a 4-story building. Rubrecht, explained that he had thought an accommodation had been reached with the neighbors by pushing it forward and adding a privacy fence. Leffler commented that he thinks most people had second thoughts after the meeting after they got home and considered how the proposed building would impact their property. Smith commented that she supports the proposed PUD. Johnson agreed, the issue is not over 7 units, the concern is regarding siting and height of the project. Severino noted that the biggest complaint is that the concept plan is 4 stories, but it does not appear that a change of 7 units is the difference between a 3 or 4 story building. The goal should be to get the nicest project possible, if the applicant is required to redesign to fewer units it will still mean a 4-story building could be built but perhaps not as nice. Whitaker agreed. Page 3 of 4

5 DRAFT COPY Petersma expressed concern about density that close to a major intersection, although the high school relocating may address some traffic issues. Motion by Whitaker seconded by Severino to approve PZ Case No ; Residences at 62W PUD. Roll Call Vote: Spencer Severino Johnson Smith Whitaker Petersma Anderson Aye X X X X Nay Abstain X 6. Other Business Wilwerding discussed the 2014 Development Summary and the Johnston Economic Development Guide. Johnson suggested a strategy meeting to discuss the large number of multifamily developments being proposed for the community. Wilwerding noted that CBRE does an annual survey, saturation hadn t been reached yet but many projects were still pending. 7. Adjournment. Meeting adjourned at 8:05 p.m. Chair Secretary Page 4 of 4

8 RESIDENTIAL ZONING DISTRICT & BULK REGULATIONS: This site is zoned C-3, Highway Commercial District with the following bulk requirements: Use Lot Area Lot Width Front Yard Setback Side Yard Rear Yard Depth C-3 20,000 s.f. 100 feet 30 feet 10/20 feet 35 feet The approved site plans do not meet the above-listed setback requirements. Specifically, the proposed south building is depicted to be constructed over the lot line of two remnant parcels. In such a scenario, the proposed building would not meet the side yard setback requirements. Staff recommended City Council approval subject to a condition for approval requiring the applicant to replat the affected lots into one legally platted lot. TRAFFIC ACCESS & CIRCULATION: SIDEWALKS: BUFFERS: PUBLIC UTILITIES: The site utilizes both a right-in/right-out and full access intersection at Merle Hay Road. An ingress/egress access easement will be filed with the final plat to allow cross-access between the two proposed lots. An existing five-foot sidewalk is shown along Merle Hay Road. No buffers are required Water: A 6 connection to the city s main within the Merle Hay Road serves the south building. Sanitary Sewer: The site plans indicate an existing 8 sanitary sewer line serves the north building. The same sanitary sewer line crosses the common lot line to serve the south building. A private sanitary sewer easement is provided to accommodate the shared connection. FLOODPLAIN: DRAINAGE: Portions of the site are located in Zone X and Zone AE of the FEMA flood plain map. The floodplain limits are clearly indicated on page C3.1.. A portion of the building and rear parking lot are located within the 100 year flood plain. The site generally drains to the west. Stormwater on site discharges at three point sources. The southeast drainage area flows to new onsite storm intakes located near the entrance drive in the southeast corner of the site. The new intakes connect to the public storm sewer in Merle Hay Road which discharges into Beaver Creek. The southwest drainage area sheet flows to the southwest across the site thru an existing wooded area and eventually into Beaver Creek. The northern drainage area sheet flows to the west to a new onsite storm intake which flows to a basin located near the southwest corner of the site. H:\Community Development\P&Z\2014 PZ\PZ 14-51; Lithia Plat 1 Final Plat Page 3 of 5

9 The new pavement addition to the west side of the existing parking lot sheet flows to the new basin as well. Stormwater from the new pond discharges along the southern property line into the existing wooded area and eventually flows into Beaver Creek. Because the stormwater detention basin spans the shared lot line between lots 1 and 2, an overland flowage and stormwater detention easement is required. CONSULTANT COMMENTS: Foth Infrastructure & Environment, LLC has reviewed the plat and offered comments in their January 20, 2015 review letter.

18 PROPERTY OWNER: ENGINEER: BACKGROUND & PRIOR APPROVALS: ABLN, LLC Represented by Dallas Patterson 2900 Delaware Ave. Des Moines, IA Emily Harding, PE Civil Design Advantage 3405 SE Crossroads Drive, Suite G Grimes, IA The subject property was annexed to the City of Johnston as part of the D&E Properties Annexation which was approved by the City Development Board on July 12, The existing R-1(75) and R-3 zoning districts were established for this site as part of the annexation. The preliminary plat for Northwood Estates (PZ Case 06-32) was approved on September 6, 2006 and the Final Plat (PZ Case 06-38) was approved on August 6, This plat created a acre Outlot Y, which included this subject property. A site plan and preliminary plat (PZ Case 07-47) depicting 60 townhome units on Outlot Y was approved on December 17, Due to economic conditions, the construction of the aforementioned townhomes did not proceed. A preliminary and final plat of Northwood Estates Plat 3 (PZ 09-19) was approved on September 8, 2009, this plat created three outlots, Outlot X, a acre parcel is the lot subject to this request and two outlots along Valley Parkway. This plat facilitated the transfer of Outlot X to Cornerstone Community Church on September 16, Those two additional lots along Valley Parkway were later rezoned to R-1(75) (PZ Case 11-28) and platted as two single family residential lots via Northwood Estates Plat 5 (PZ Case 12-02). Plats 3 and 5, which prevented Outlot X from having access to Valley Parkway were only recommended for approval by Staff as the site was proposed for development for a church, which did not need the additional land or additional street/drive connection to Valley Parkway. On December 26, 2006, Cornerstone Community Church sold the property to Kubra Corporation and plan to develop their church elsewhere in the community. Upon transfer, Kubra Corporation requested a Comprehensive Plan H:\Community Development\P&Z\2015 PZ\PZ 15-01; Northwood Home Association SP Page 3 of 8

19 Amendment from Quasi Public to Medium Density Residential. This change, Johnston 2030 Comprehensive Plan Amendment # 1 was approved on July 15, 2013 via Resolution Following the amendment, the property was rezoned from R-3 Medium Density Residential to PUD, via Ordinance 881 which was approved on August 3, The PUD allows R-3 uses, included detached townhomes, the PUD was necessary as the R-3 district doesn t allow detached residential units. The Site Plan and Preliminary Plat for the Villas at Northwood with 40 single family detached townhome lots and was previously approved on May 5 th, 2014 by Resolution The Final Plat for the Villas at Northwood of 40 single family detached townhome lots and was previously approved by the P&Z July 28 th, 2014, however was never approved by the City Council. COMPREHENSIVE PLAN: The Johnston 2030 Land Use Plan reclassified the subject property as Quasi-Public due to the planned development of the property as a church. Prior to the adoption of the Johnston 2030 Plan on December 6, 2010, the property was within the Northwest Area plan of the Comprehensive Plan which was amended for this area by the City Council on February 6, This area was designated as High Density Residential (up to 8 units per acre) in the plan. As noted, following an amendment the parcel is designed as Medium Density Residential (5 to 8 units per acre), the proposed use is in conformance with the plan. EXISTING ZONING: The subject property is currently zoned PUD, via Ordinance 881 with R-3 Medium Density Multiple Family Residential uses allowed, with the following bulk requirements: Maximum Density 7.0 units per acre Minimum lot size: 500 square feet (postage stamp lot with common space) Minimum separation between principal buildings for detached townhomes: 10 feet Minimum setback from PUD boundaries: 35 foot Minimum separation between garage and edge of common drive: 25 feet Single family detached homes are permitted in the PUD. ADJACENT LAND USES: North: As noted, the property immediately north contains two single family residential homes, created by Northwood Estates Plat 5 and are zoned R-1(75). H:\Community Development\P&Z\2015 PZ\PZ 15-01; Northwood Home Association SP Page 4 of 8

20 West: The property to the west is developed as single family residential lots created by Northwood Estates Plat 1 and are zoned R-1(75). South: Immediately south of the property is NW 70 th Avenue. To the south of NW 70 th Avenue, the property is undeveloped and zoned A-R Agricultural Reserve, but is designated in the Johnston 2030 Comp Plan as Medium Density Residential with Office uses to the southeast. East: The property adjacent to this site is currently zoned PC Professional Commerce and C-1 Neighborhood Commercial. However, after a lengthy discussion during the development of the Johnston 2030 Plan, the land use designation for this property was changed from Commercial to Medium Density Residential as the feeling was that there were more commercial property designations than the area could support and the long term most realistic use would be residential. While the plan was amended, the underlying zoning was not, so office and commercial uses remain as allowed uses of the site. TRAFFIC ACCESS & CIRCULATION: As noted in the Background section of this report, this site was originally intended for development as a multi family townhome development. As such, the site was originally depicted with access from NW 70 th Avenue (right-in, right-out), a 50 foot-wide private drive access to Peckham Street between two single-family lots, and access to Valley Parkway at the north. When the property was transferred to the church, there was no longer need for an access to Valley Parkway and two lots were created at the north end of the parcel for residential development. As proposed by this site plan, a townhome association would be created to own and maintain all streets, with access from NW 70 th Avenue (right-in, right-out), and a 26 foot-wide private drive, within the 50 foot wide lot which provides access to Peckham Street between two single-family lots. This street provides access to a fullaccess intersection at Peckham and NW 70 th Avenue. Reconstruction of NW 70 th Avenue to a four lane roadway with medians/turn lanes, is currently in the city s capital improvements plan scheduled to be constructed This project will result in construction of a median adjacent to the subject site limiting access to right-in/right-out only. The intersection of NW 70 th Avenue and Peckham is proposed to be controlled with the construction of a roundabout, providing full access. BUFFERS: Buffers are required between differing land uses; including a 20 foot buffer along the north and west property boundaries adjacent to H:\Community Development\P&Z\2015 PZ\PZ 15-01; Northwood Home Association SP Page 5 of 8

21 single family residential. Additionally, the developer would be responsible for the installation of half of a 30 foot buffer where the site is adjacent to the PC zoning district and half of a 50 foot buffer where the site is adjacent to the C-1 zoning district to the east. Sheet 11 of the site plans depicts each of these buffers and the required planting within them. Installation of the buffers will be required prior to the completion of the homes adjacent to the buffers. PARKLAND DEDICATION: PUBLIC UTILITIES: This project is required to meet the Parkland Dedication requirements of Chapter of the City of Johnston Code of Ordinances. The Northwood Estates Preliminary Plat and the Johnston 2030 Trail Plan depict a trail running north/south through this site from NW 70 th Avenue to Valley Parkway. The PUD Master Plan depicts this trail along the western plat boundary and the PUD Ordinance requires its construction to satisfy the parkland dedication requirements. The northern portion of this trail is installed within Northwood Estates Plat 5, and this trail will be connected to Peckham Street as part of the reconstruction of NW 70 th Avenue. Sanitary Sewer: Sanitary sewer exists along the south side of NW 70 th Avenue, this main can provided service to the subject property, however, the applicants will be required to bore a main under NW 70 th Avenue. All of the sanitary sewer within the subdivision will be privately owned/maintained by the association. Water: An eight inch water main exists between the two single family residential homes created in Northwood Estates Plat 5 to the north of the subject property and the applicants would be required to connect to the main. In addition, the system will be looped to the existing twelve inch main along NW 70 th Avenue. This looping will improve water supply to the entire Northwood Estates subdivision and as such will be public main. STORMWATER MANAGEMENT: Generally, the site drains easterly/north easterly. The subject property contains an existing storm sewer and overland flowage easement and detention basin on the northern portion of the property, this basin extends northerly to the rear of the two adjacent single family lots in Northwood Estates Plat 5, where a Detention Easement also exists. This basin drains via an outlet easterly to the adjacent undeveloped property and was required to address the stormwater management from the single family Northwood Estates Plat 1 development. The existing detention basin does not address the City s current Water Quality Volume or Channel Protection Volume requirements and is not sized to accommodate the additional development proposed with this project. As such, the applicants are proposing a series of smaller detention facilities located in the rear of H:\Community Development\P&Z\2015 PZ\PZ 15-01; Northwood Home Association SP Page 6 of 8

22 lots 4 and 5, 24 and 25, 22 and 23, and which all drain via storm sewer to the existing basin on northern side of the property. Said basin will be regraded and significantly increased in size. This basin will also include a tile subdrain system to allow for the infiltration of the water quality volume and to ensure basin drains as quickly as possible. The water quality volume is designed to reach an elevation of , the lowest point of the adjacent basin to the north is 845, this will ensure that smaller storm events (generally less an 1.25 inches) will be addressed in the new portion of the basin without spilling into the portion of the basin on the adjacent parcels to the north. Larger storm events will back up into the basin on the adjacent properties to the north as they do today, with the 100 year storm elevation of the basin projected to increase by six inches from to , however the top of berm/overtop elevation will be lowered from to Thus for extreme storm events the basin will over top at a foot below where it does today providing better protection to the adjacent properties which have minimum protection elevations of With the previous preliminary plat/site plan approval for the subject property (PZ Case approving 40 lots), the property owners of the two residential parcels in north-adjacent Northwood Estates Plat 5 provided numerous s regarding their concerns with stormwater in the area. The applicant s engineer, as well as the City s engineer have extensively reviewed the stormwater management design to ensure it meets the City s requirements, that the basin functions properly and that neighbor concerns are addressed if possible. Additionally, staff is recommending a condition of approval requiring an as built survey of the basin prior to the issuance of a building permit for any structure within the plat to ensure the basin is constructed properly. As noted above, the installation of a subdrain system in the lowest portion of the basin within the Northwood Home Association site and the lowering of the basin overflow will improve the overall function of the detention basin; however, both portion of the basin will continue to function as a detention basin, within the confines of the existing easement areas, as it was/is designed to do.
