CLOUD,MN ❑CHIPPEWA FALLS, WI 0 MADISON, WI 0 LAKE COUNTY, IN TO: Mike Ulrich, Public Works Director, City of Mounds View FROM: Glen Van Wormer, Manager, Transportation Engineering Group A DATE: June 19, 1998 RE: Mounds View, Minnesota Highway 10 and Edgewood Drive SEH No. A-MOUND9708.00 The relocation of the Edgewood Drive intersection on TH 10 is based on many factors. The existing intersection is at a very skewed angle, as are several others along TH 10. However,this intersection is also quite close to County Road 1-12. In order to prevent operational problems along TH 10, the relocated signalized intersection must be located at the approximate mid-point between the two existing signals on TH 10 at County Road H2 and at Long Lake Road. This location also best fits the connection to the city street proposed for the west side of TH 10 connecting to County Road H2 and providing access to the proposed development on the west side of TH 10. The proposed traffic signal for the new intersection is justified by traffic volumes from the expanded Community Center across from City Hall and from the development proposed on the west side of TH 10. Funding for the relocation is partially coming from the development on the west side. Mn/DOT has not agreed to fund any portion of the relocation of the intersection or the traffic signal, despite the improvements to TH 10_ To accommodate the location requirements of the intersection for traffic signals and for the development on the west side of TH 10, Edgewood Drive must be curved as it passes City Hall. It is desirable to provide a smooth 30 mph design speed curve. This design provides good traffic operations. Lesser design speeds have poor operations, including safety concerns of vehicles traveling over the centerline or hitting the curb. This has been demonstrated in instances where a low speed curve has been placed on an arterial street. This particular area also needs adequate sight distance along relocated Edgewood Drive to the entrances to the Community Center parking lot, relocated City Hall entrance and the entrance to the potential development in the area south of the relocated Edgewood Drive. Finally, in order to obtain Municipal State Aid funds for Edgewood Drive, a 30 mph design speed is necessary. The original concept provided a 30 mph design speed had significant impacts on the City Hall parking lot. To maintain the number of parking spaces currently provided, a concept of extending
