City of Arden Hills Planning Commission Meeting for January 10, 2018 P:\Planning\Planning Cases\2017\PC 17-029 - 3685 New Brighton Road Preliminary and Final Plat and Easement Vacation\Memos_Reports_17-029 Page 3 of 14 3. Site Data: Future Land Use Plan: Low Density Residential Existing Land Use: Single-Family Detached Residential Zoning: R-2: Single & Two Family Residential Lot Size: 83,253 square feet (1.91 acres) Topography: Property slopes east to west approximately 28 feet from New Brighton Road to the wetland complex on the western boundary. Plan Review 1. Chapter 11, Subdivision Regulations Review A. Street Plan and Streets No new streets would be constructed for the Horita Acres subdivision. All three lots will have access on Thom Drive. The existing property has an access driveway on New Brighton Road. As a condition of approval, the driveway will be required to be relocated to Thom Drive. New Brighton Road is a Ramsey County roadway and the County has reviewed and approved the access relocation. All other requirements pertaining to driveway location and grades are met by the proposed plans. B. Easements City subdivision regulations require a 12-foot wide utility and drainage easements dedicated to the City along the right-of-way and centered on common lot lines. The Preliminary and Final Plats include 12-foot utility and drainage easements centered on the common lots lines throughout the development and a 12-foot easement along the Thom Drive and New Brighton Road right-of-way, and along the shared lot line with the property to the north. The Public Works Director/City Engineer has commented that the drainage easement to the north of the building site on Lot 2 will need to be widened from 10 feet to 12 feet. This will need to be revised on the Final Plat before the plat is signed by the City. The property is traversed by a wetland area along the western boundary of the lot that extends off site to the north and south. In order to satisfy Rice Creek Watershed District requirements, the development will be required to construct two basins on Lot 1 that will capture stormwater runoff from the entire site and allow water to discharge into the adjacent wetland area. The Subdivision Code requires that a drainage easement be provided for wetland areas and stormwater management facilities. The plat provides adequate easements for the wetland, but the Final Plat will need to be revised so that the drainage easements around the two ponding areas are taken to two feet above the emergency overflow elevation of each basin.
