Overview of Request The existing property at 3685 New Brighton Road is approximately 1.9 acres in size and is comprised of a single-family residential dwelling, detached garage, and shed. The dwelling and accessory structures are located towards the eastern side of the property and the one access driveway for the lot is on New Brighton Road near the intersection with Thom Drive. The property as approximately 124 feet on frontage on New Brighton Road and 378 feet of frontage along Thom Drive. The existing topography of the lot generally slopes west from New Brighton Road to a wetland complex located on the western parcel boundary. This wetland complex covers approximately 0.3 acres of the property and extends off the property to the north and south. The City has a sanitary lift station located on the southern edge of the property approximately in the middle of the lot. The remainder of the lot is heavily wooded. The applicant has proposed a subdivision of the existing property to create three lots for single- family residential dwellings. The existing dwelling and other improvements would be retained and located on the proposed Lot 3. Two new lots (Lot 1 and Lot 2) would be located to the west of Lot 3 with frontage and driveways on Thom Drive. The existing access driveway for Lot 3 would be located to Thom Drive so that all three parcels are similarly oriented with their principal frontage on Thom Drive. There is a purchase agreement in place for the easterly lot (Lot 2) and the applicant expects construction to begin on this lot immediately if City approval is received. The westerly lot (Lot 1) is being marketed for sale. In order to support the proposed development, a Preliminary Plat, Final Plat, and Vacation of Easement is requested. The easement vacation is needed to vacate a portion of the public utility easement for the City lift station on the property. The development is required to meet Rice Creek Watershed District regulations and the proposed grading plan shows that two basins would be constructed on Lot 1 to capture stormwater runoff from the site and allow it to discharge into the adjacent wetland. Lot 1 and Lot 2 would be graded to direct water flow from these properties to one of the two basins. The site is heavily wooded with 72 significant trees. A Tree Preservation Plan has been provided indicating 22 of these trees would be removed. Replacement tree plantings are proposed as part of the Tree Preservation Plan. The applicant has submitted a development plan set (Attachment C), Final Plat (Attachment D), and proposed easement vacation plan (Attachment E).
