FinM Plat and Final Site Plan Review Rum River Meadows May 19, 2006 Page 3 of 6 As directed in the preliminau/plat, the private stub street (Neon St. NW) has been changed to a public street. The final plat sheet indicates the right-of~way being dedicated as 66 feet. The drainage, street, and utility plans show a 60-feet right-of-way. The City only requires a 60-foot right-of-way. Please correct the final plat sheet. Staff will continue to review the plans and may have future comments/corrections to the submitted plan. 9. Grading and Drainage. Grading, Drainage and Utility plans have been prepared by TEC Design We have some specific comments regarding these plans: The minimnm floor elevation ibr all units on tire north side of the road must be 870.0 which is 2 feet above the 100 year water level of the existing and proposed ponds. The new pond in the middle of the site should be connected to tile existing pond m River Pines > with a p~pe or by excavanng to join the ponds. The plans bare grades less than 1% ~vlzich is not permitted and man), areas are less than 2% which reqnire certificates of grading before occupancy permits are issued. = Cmmection to the existing lift statiou in River Pines 3rd subdivision is required· The Street connection and utility connections assume construction of the Shade Tree Cottages development. Constrtlction of this development will require acquisition of easements, preparation of additional plans and construction outside the limits of the property if ibr any reason the Shade Tree Cottages development is delayed or not constructed. The proposed plans show filling outside the wetlands but below the I00 year high water level of the wetlands. Filling o/f flood storage volume can only be approved by performing additional engineering calculations· The calculations consist of the following steps: 1. Detmynine the existing and proposed flood storage volumes on the parcel. 2. Calculate d~e percentage of volume lost due to tbe proposed fill. 3. Apply the same percentage of volnme change to all parcels abutting the wet[and. ' 4. Calculate the new 100 year flood volume for the wetland. · If the increase in elevation is less than 0.5 Pt and will not impact existing structures then the filling can be approved. Staff will continue to review the plans and may have future comments/co~tcections to the submitted plan. 10. Wetlands. The subject property contains several wetlands. The City has received the wetland delineation report for this development. This report must also be forwarded to the Lower Rum River Water Management Organization for verification. The plan is showing several areas where the wetlands will be impacted by constructign. A seqnencing plan tbr the impacts and mitigation inust be submitted to the and Lower Rum River WMO. Final plat approval will be contingent on approval by the Lower Rum WMO of'the mitigation plan.
