RE: Oneka Lake Reserve <br />March 15, 2021 <br />The developer proposes to plat a 0.45 acre public neighborhood park in the southwest corner of the site. <br />The plans show a conceptual layout designed to serve the anticipate needs of young families and visiting <br />grandchildren within this neighborhood and the surrounding area. Park amenities could include a <br />playground with equipment designed for younger children, a gazebo with picnic tables for smaller <br />gatherings and/or a trike track to give the youngsters a place to ride safely. It is proposed that the land for <br />the park satisfy part of the developer's park dedication requirements with the balance made up through a <br />cash dedication. Alternatively, the developer could construct a portion of the park up to the value of the <br />cash dedication. <br />Stormwater will be managed through a combination of an onsite pond, expansion of the existing <br />stormwater pond to the north of this site and the purchase of water quality credits from the city. Water <br />from the onsite pond will be utilized for a centralized irrigation system. The development will be served by <br />publicly owned utilities installed to city standards within an easement under the roadway. <br />The 40 townhomes can be expected to generate on average 8 trips per unit per day or 320 total. The park <br />will generate minimal vehicular traffic. <br />ZONING <br />The site and the properties to the south, west and east are presently zoned R-4 Low Density Multiple Family <br />Residential. The properties to the southwest are zoned CR-3 Central Residential. To the northwest the <br />property is zoned 1-3 General Industrial. The property to the north is zoned R-3 Single Family Detached <br />Residential. <br />The R-4 District permits the townhomes as proposed at a density of three to six units per acre. The density <br />can be increased to eight units per acre under a PUD. The gross density of the development will be 6 units <br />per acre or 6.4 units per acre net of the park. <br />In addition to an increase in density, rezoning to PUD is necessary to allow the proposed private street and <br />flexibility for building setbacks.
