The traffic increase from both the background growth and the development results in a need for capacity improvements at individual roadways and 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 will still be 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 to year 2040. Exact timing for improvements will be based upon the actual development timing and background traffic growth. Short Term improvements can be considered as the minimum requirements based on projected traffic growth. Mid Term and Long Term improvements are considerations and may ultimately be required to serve the area. Short Term Improvements • Bunker Lake Boulevard (west of Armstrong Boulevard): Expand to a four lane section for development. o The eastbound approach should include two 300 foot 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 feet from Armstrong Boulevard and a right in/right out access should be at least 470 feet 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) will be determined based on 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) will be determined based on 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. Prepared by: Bolton & Menk, Inc. ADDITIONAL ANALYSIS City of Ramsey — Future Business Park Page 7
