Preliminary, Plat Review: Wildlife Sanctuary 3~d Addition October 31, 2002 Page 2 of 5 5. Access and Streets: The development will e~end Junkite Street'N.W. north off of Alpine Street and terminate in a cul-de-sac at the north end of the property because of the presence of wetlands. Street extensions are also planned to connect with 154~ Lane N.W. and 155~ Lane N.Wi in Sumqower Ridge to the east. ~The preliminary plat also proposes to extend 155~' Lane to the west boundary of the property for future access to the west; it will constructed with a temporary cul-de-sac and signed as a future through street. An escrow should be collected in an amount sufficient to cover the costs associated with removing the temporary, cul-de-sac, restoring adjacent properties, and extending the sidewalk to the western boundary of the plat when development occurs to the west. Neither the permanent cul-de-sac to the north nor the temporary cul-de-sac to the west exceed the 600 foot length restriction. Grading and Drainage: A Preliminary Grading Plan dated October 2, 2002 has been received at the City. A permit from the Lower Rum River Watershed. Management Organization and the Minnesota Pollution Control Agency will be required. The developer is responsible for. obtaining any and all permits required from other regulatory agencies. Wetlands must be delineated and dedicated on the f'mal plat as drainage and utility easements. The City has enacted an ordinance that requires an elevation survey at the time of footing inspection to ensure compliance with the approved grading plan. As required, the preliminary grading plan identifies which type of house style is permitted on each lot. This information should be carried forward onto the final grading plan also. No grades shall be .flatter than 1%. Grades flatter than 2% will require a certificate of grading prior to an occupancy permit being granted. The requirement for an elevation survey on ali footing inspections and the requirement for a certificate of grading on.lots with less than a 2% grade must be stated on the final grading plan. The following comments are based on the Preliminary Grading Plan dated October 2, 2002: Elevations must be provided on all property corners and critical elevations where a change of slope occurs.
