Zoning File #2108 February' 14,1996 Page 3 is included in one contiguous parcel and both murucipal sewer and legal access is available to that building site without encroachment on the protected area." In the final plat. Lot 3 must be assured of */j acre dry contiguous building site to the east of the ravine and the access drive must not encroach the ravine area. Major portions of this property drains to the south and east through Lot 5 to a less dramatic ravine area that drains under W'iMhurst Trail to a low/wetland area that eventually drains to the lake. As the Engineer's report notes. E.xhibit H, both drainageways have a high potential for erosion. The City will require storm water ponding to reduce the runoff flows and velocities leaving the site. The applicant must provide drainage and ponding calculations that should include a skimmer structure at pond outlet. This information must be submitted with the preliminary plat application. The City Engineer recommends that the grading and drainage plans be submitted to the Minnehaha Creek Watershed District for their review at the time the preliminary plan is submitted to the City. Grading plans submitted with the formal application must include existing and proposed 2’ contours. The plans must include the following: - Erosion control. Building pad locations and elevations. Location of bluff impact zone and required setback from defined top of bluff. Temporary erosion control during construction. There are no designated wetlands within the seven acre property. The major ravine and drainage way at the northern portion of the property was never designated on the City's wetland maps. Utilities. Sanitary sewer is available to this property'. Water service will be provided by on site wells. Refer to Exhibit C, sanitary' sewer w ill be extended approximately 310' north to the intersection of Wildhurst and the private road. The Engineer has asked the City to consider three options concerning current access and sewer to the seven acre site and future service to landlocked properties to the west and north of the subject property. Refer to Exhibits B and I, the Engineer recommends that the southern portions of unimproved Garden Lane be vacated and replatted within the seven ..ere parcel providing direct access to the undeveloped parcels to the north and west via newly realigned Garden Lane. Sewer easements can be extended to the western boundaries of the property so that future sewer service can be extended from the west lot line. Refer to Exhibits 11. 1, J-1 and J-2. staff has sketched access scenarios based on City Engineer's report. E.xhibit I shows Garden Lane realigned extended to west boundary (to meet Lot 3 west lot line), J-1 shows a private road outlot with future extension to west along with sewer easement. Lot 3 is defined as a back lot with sewer and access provided in 30'
