EXECUTIVE SUMMARY The Future Business Park development is proposed north of T.H. 10 and west of Armstrong Boulevard. Armstrong Boulevard is a critical north -south corridor for the City of Ramsey, Anoka County, and the region carrying traffic from Trunk Highway (T.H.) 10 to surrounding areas. The Business Park development includes residential, business park, commercial, and institutional land uses. These land uses result in an increase of approximately 18,500 to 23,300 trips per day into and out of the area at full build. The traffic increase from both the background growth and the development results in a need for capacity improvements at individual intersections in the study area. The following concise summary of improvements should be completed based on the mitigation necessary to achieve acceptable operations. For the 2040 Full -Build scenario, operations can be improved, but are still considered unacceptable at many of the intersections. This is due to the large amount of traffic entering and exiting on Bunker Lake Boulevard and Armstrong Boulevard. Short term improvements are intended to mitigate current safety or operations problems, mid-term improvements are needed to accommodate both development and background traffic growth, and long-term improvements are needed to handle the overall development out to 2040. Exact timing for improvements should be based upon the actual development timing and background traffic growth. A. Short Term • Bunker Lake Boulevard (west of Armstrong Blvd): Expand to a four lane section for development. o The eastbound approach should include two 300 ft left turn lanes, two through lanes, and one right turn lane. o A full median should be provided to the west end of the commercial area. o A full access should be at least 845 ft from Armstrong Boulevard and a right in/right out access should be at least 470 ft from Armstrong Boulevard. • Bunker Lake Boulevard (west of commercial section): Expand to a three lane section for development (two through lanes and one center left turn lane). o Right turn lanes (locations and lengths) are to be dictated by development type. • Puma Street: Expand to a three lane section for development (two through lanes and one center left turn lane). o Right turn lanes (locations and lengths) are to be dictated by development type. • Bunker Lake Boulevard & Puma Street: An all -way stop, two-way stop, or roundabout will operate adequately at this intersection for the 2040 Full -Build conditions. The roundabout option may offer better operations than the other two options at 2040 Full - Build. B. Mid -Term • Armstrong Boulevard & Alpine Drive: Add northbound and southbound left turn lanes. Modify eastbound and westbound lanes to include a thru/left and a right turn lane. • Alpine Drive & Puma Street: Add a westbound left turn lane and eastbound right turn lane. • Armstrong Boulevard & Bunker Lake Boulevard: Re -stripe southbound lanes to include Prepared by: Bolton & Menk, Inc. — R16.109828 Executive Summary Future Business Park Page 1
