Spring Hill Golf Course Access Road Functions and Traffic Volumes County Road 6 is a high speed arterial highway designed for movement of higher volumes of traffic. Spring hill road is a low speed collector roadway designed to carry lower traffic volumes, and to provide access to adjoining properties. Sound traffic engineering practice is to use local collector roads to provide access to adjoining properties and direct traffic onto arterial highways at limited access points. The purpose of this concept is to reduce the number of conflicfpoints along arterial highways that are carrying higher volumes of traffic. " The Hennepin County Highway Department was asked to review this project. Their review comments are for the elimination of access points along countyJiighway 6 and for the golf course access to be provided from local streets. This reconunendation is in conformance with the previously described traffic engineering principles. For comparison purposes peak hour traffic volumes are listed below for both roads. These volumes were obtained fi:om traffic studies completed by the Minnesota department of Transportation for the proposed Highway 12 relocation project. Projected volumes for the year 2015 with the new highway 12 located along the north side of the railroad tracks are as follows. County Highway 6, West of Spring Hill Road 703 Vehicles per Hour (Both Directions) County Highway 6, East of Spring Hill Road 1050 Vehicles per hour (Both Directions) Spring Hill Road- 328 Vehicles per Hour (Both Directions) These traffic volumes show that the county road is carrying more than double the traffic of Spring Hill Road. Also the traffic speeds on County Road 6 are higher than on Spring Hill Road. Road Network Layout Thejouthemacoess4o the project area from the Highway. 12 corridor is a concern. East Long Lake Road is narrow and winding along the eastern edge of Long Lake. The road width and alignment are constrained by a steep bluff on one side and the lake on the other side of the road. Projected traffic volumes in the EAW indicate 50 daily trips to the site from the south. If the golf course was to change to a public course in the future, the number of daily trips from the south would increase several times. The amount of traffic that will use East Long Lake Road to access the golf course is more a function of the area transportation network than a function of the location of the golf course access. Traffic in the Long Lake Highway 12 area will tend to use East Long Lake Road because the alternative north/south roadways are out of the way both to the east and to the west. 1
