The proposed development requires consideration of applications for preliminary plat approval and a PUD -CUP to allow for development of the proposed subdivision within a Shoreland Overlay District, proposed lot standards, and community center building. A public hearing has been noticed for the Planning Commission meeting on 18 July 2016 to consider the application. Exhibits: A. Site Location B. Martin Farms 4th Addition Preliminary Plat Submittal dated 06/01/16 ANALYSIS Comprehensive Plan. The 2012 Otsego Comprehensive Plan includes the subject site within the West Sewer District and guides the area for low-to-medium density residential uses. The proposed subdivision of single family lots based on the lot requirements of the R-6 District is consistent with the future land uses guided by the Comprehensive Plan. City staff has completed an analysis of available sanitary sewer capacity within the West Sewer District and determined that sufficient capacity exists to provide service to the proposed preliminary plat in accordance with the policies of the Comprehensive Plan. Actual allocation of sanitary sewer service is reserved only with approved final plats that have paid utility availability charges. Zoning. The subject site was zoned R-6, Residential Medium Density Residential District with the Phase 1 application approved on 28 July 2003. The R-6 District allows for single family dwellings as proposed on the current preliminary plat application as a permitted use. The proposed private community building to be developed on Outlot B is allowed within the R-6 District as a conditional use. Allowance of the private community building and flexibility in the application of the lot requirements for the R-6 District are being requested as a PUD -CUP. Consideration of the PUD -CUP is to be based upon, but not limited to, the criteria outlined in Section 20-4-2.F of the Zoning Ordinance. A portion of the southwest corner of the subject site is also with in a Shoreland Overlay District of a Natural Environment lake located south of 701h Street. The portion of the subject site within the Shoreland Overlay District to be preliminary platted as Outlot D as a future phase of development. The current preliminary plat of 99 single family lots and the proposed private community building are not subject to the performance standards of the Shoreland Overlay District. Environmental Review. An EAW was prepared with the review of the Phase 1 development applications for Martin Farms and its scope included the planned development of future phases including the subject site. The City Council adopted findings on 28 July 2003 that the proposed subdivision did not have potential for significant environmental effects and that an Environmental Impact Statement was not to be required. The current preliminary plat application requires no additional environmental review. Surrounding Land Uses. The subject site is surrounded by the following existing and/or planned land uses. Direction Land Use Plan Zoning Map Existing Land Use North LD Residential R-6 District Single Family (Martin Farms) East LD Residential LD/MD Residential R-4 District R-6 District Single family (Martin Farms) South Albertville Albertville Single family dwellings West LD Residential A-1 District R-3 District Agriculture Single Family (Meyer Addition) The single family lots proposed to be subdivided within the subject site are similar in character with existing single family lots developed in earlier phases of Martin Farms as well as planned land uses to the west. The subject site abuts the Meyer Addition to the west that was platted as one acre lots to be served by individual on-site septic systems and wells prior to construction of the City's West Wastewater Treatment Facility. All but one of the 16 lots of the Meyer Addition are vacant and under common ownership with the surrounding undeveloped agricultural parcel. The Meyer Addition and agricultural parcel are within the West Sewer 2 District and utilities are available to serve urban development of these properties. City staff anticipates that the 15 vacant lots within the Meyer Addition may be resubdivided as part of an overall subdivision with the agricultural parcel to take advantage of the densities allowed with municipal sanitary sewer and water utilities. On this basis, City staff recommends not requiring the transitional lot area and width for Lots 7-14, Block 5 specified by Section 20-67-8 of the Zoning Ordinance as part of the PUD -CUP. Access. The preliminary plat provides two accesses to MacIver Avenue, which is designated by the 2012 Comprehensive Plan as a residential collector street. The north access is aligned with 73rd Street on the east side of the roadway. The south access is 1,050 feet from the north access exceeding the 500 foot requirement of Section 21-7-7.N of the Subdivision Ordinance for intersection spacing to collector streets. A future access to 70th Street will be provided by extending Larabee Avenue at the time Outlot D is developed consistent with the original development plans for Martin Farms approved with Phase 1. The preliminary Plat also provides that 73rd Street is extended to the west plat line to provide future access for development of the abutting agricultural parcel. Because of the existing Meyer Addition and wetlands to the north, this is the only feasible neighborhood connection for the preliminary plat. The developer will be required to pay the transportation fee for MacIver Avenue at the time of final plat approval. Streets. All of the lots within the preliminary plat will be accessed via public streets. The proposed public streets are 28 feet wide with concrete curb and gutter within 60 foot rights-of- way. A five-foot concrete sidewalk is provided on one side of all streets. The plans for the proposed public streets are consistent with the requirements of the Engineering Manual and are subject to review and approval by the City Engineer. There are no cul-de-sac streets shown on the preliminary plat. Street names will be established at the time of final plat approval in accordance with Section 21-7-7.Q of the Subdivision Ordinance and the Wright County grid system and are subject to approval of City staff. Lot Requirements. The R-6 District establishes the following minimum lot requirements: The mean area of the proposed 99 lots is 12,360 square feet exceeding the larger minimum 12,000 square foot lot requirement of the R-4, Single Family Urban District. The developer is also requesting flexibility on setback requirements of 25 feet for the front yard and side yard of a corner lot measured to the principal building and 30 feet to the garage face, which the City has previously allowed for R-5 and R-6 District developments to make more efficient use of the smaller lot area in these districts. 13 Lot Area Lot Width Lot Depth Setbacks Front Side Rear Wetland MacIver Ave. R-6 Interior 9,OOOsf.

The mean area of the proposed 99 lots is 12,360 square feet exceeding the larger minimum 12,000 square foot lot requirement of the R-4, Single Family Urban District. The developer is also requesting flexibility on setback requirements of 25 feet for the front yard and side yard of a corner lot measured to the principal building and 30 feet to the garage face, which the City has previously allowed for R-5 and R-6 District developments to make more efficient use of the smaller lot area in these districts. 13 Landscaping. Landscaping of two trees per lot is required to be planted in accordance with Section 20-19-2.B.1 of the Zoning Ordinance, which have been provided as 198 boulevard trees along public streets complying with the number of trees required. Section 20-19-3.B of the Zoning Ordinance also requires a berm/landscaping be installed along the lot lines along MacIver Avenue of Lots 1, Block 1 and Lot 1-11, Block 2. A landscape plan illustrating the boulevard trees and required buffer yard has been submitted and the plantings and planting sizes comply with the requirements of the Zoning Ordinance. Secondary Dwellings. The developer is proposing to make available their NextGen housing products, which incorporate a secondary dwelling unit into the principal building (effectively a Mother -In -Law apartment). The R-6 District allows for two-family dwelling units as permitted uses, but each of the lots is proposed to be developed with single family dwellings. Availability of the NextGen housing product is a unique offering that expands housing choices and reflects changing demographics that the City previously approved in the Meadows of Riverpointe subdivision for the same developer. City staff recommends the NextGen housing be allowed within the preliminary plat as part of the PUD -CUP subject to the same standards approved before: The design and construction of the principal building is not a two-family dwelling as defined by the Zoning Ordinance. 2. There shall be an interior connection between the main living area and accessory living quarters that is able to be unlocked from each side of the connection and that is not secured by a deadbolt or keyed lockset. 3. The principal building shall be served by single municipal water, sanitary sewer, gas and/or electric utility service lines each with a single meter for the respective utility where applicable. 4. The principal building shall have one heating and air conditioning system. 5. The property shall have one postal address. 6. There shall be a minimum of three (3) garage stalls having direct exterior access (not in a tandem arrangement) attached to the principal building with a driveway access in front of each stall so as to allow direct vehicle maneuvering to each of the stalls. Private Community Building. The submitted plans include development of Outlot B with a private community building, which includes an outdoor pool. The developer is proposing the private community building be setback 20 feet from the front property line due to the adjacent wetland and need to maximize space for outdoor use to the rear of the building. City staff supports that proposed front yard setback be accommodated as part of the PUD -CUP. The side yard setback for the proposed community building from Lot 1, Block 6 is 20 feet or more than double the required side yard setback of the R-6 District. The landscape plan must be revised to provide for either a staggered row of evergreen trees or hedge row of tall growing arborvitae shrubs in the side yard abutting Lot 1, Block 6 to provide screening, as well as a general plan for planting of the lot. The provision of a pool will also require fencing as required by Section 20-18-5.0 of the Zoning Ordinance. The preliminary plat must be revised to designate Outlot B as a lot/block as Section 20-16-3.G of the Zoning Ordinance prohibits issuance of a building permit for outlots. The developer will need to provide documentation that the private community building will be conveyed to the existing Martin Farms HOA or a separate HOA for long term ownership and maintenance. Park and Trail Dedication. The Future Parks and Trails System Plan included in the 2012 Comprehensive Plan does not designate any area within the area of the preliminary plat for additional park land acquisition. As such, park and trail dedication requirements for the subject site will be satisfied by payment of a cash fee in lieu of land calculated on a per lot basis at the time of final plat approval. Grading and Drainage Plan. The applicant has submitted grading and drainage plans for the proposed preliminary plat. Section 20-16-5.F.4.a of the Zoning Ordinance requires establishment of a 20 foot vegetative buffer at the delineated edge of all wetlands. The developer is proposing to average the width of the wetland buffer as part of the PUD -CUP for the wetland overlaying the north plat line due to the fixed location of an existing water main that was constructed with Phase 1 of Martin Farms (and Zimmer Farms) and changes to the wetland since that time that reduces the depth of the area between the street corridor and the wetland. Section 21-7-15 of the Subdivision requires that storm water basins and wetlands be included within outlots platted and deeded to the City, which is shown on the preliminary plat. There are wetland buffers within Outlot B to be developed as the private community building which is acceptable subject to recording of a conservation easement with the final plat. The grading and drainage plans are subject to review and approval by the City Engineer. The developer will also be required to pay a stormwater impact fee at the time of final plat approval. Utility Plan. The applicant has submitted utility plans for extension of sanitary sewer and water utilities to serve the proposed lots. All utility plans and issues are subject to review and approval of the City Engineer. The developer will be required to pay the Sewer Availability Charge and Water Availability Charge in effect at the time of final plat approval. Drainage and Utility Easements. Drainage and utility easements are also shown to be dedicated at the perimeter of all lots as required by Section 21-7-15.A of the Subdivision Ordinance. All drainage and utility easements are subject to review and approval by the City Engineer. 5 Outlots. The preliminary plat includes five outlots summarized below. As noted, Outlot B will be required to be designated as a lot/block on the final plat to be eligible for a building permit in accordance with Section 20-16-3.G of the Zoning Ordinance. Outlot Purpose Ownership A Storm water basin City B Private community building HOA C, E Wetland/wetland buffer/Stormwater basin City D Future phase Developer Final Plat. Upon approval of a preliminary plat, the developer must submit application for final plat, which is subject to City staff review and approval by the City Council. The final plat approval includes execution of a development contract to memorialize all of the conditions of approval and provide for payment of applicable fees.
