Both MnDOT and Anoka County were engaged during the previous study process. Comments from both agencies are reflected in the improvements considered in this report. Previous Improvements Significant consideration and planning was completed prior to completion of the improvements constructed in 2011. Those improvements included street, trail, sanitary sewer and water distribution. Additionally, consideration was given to storm water management strategies and a potential 30-inch raw watermain from a future intake on the Mississippi River to the proposed site of the water treatment plant, just south of Fire Station No. 1. All previous analyses and reports are considered as a part of this analysis. VI. ADDITIONAL ANALYSIS In the previous analysis, we completed traffic and storm water studies and reviewed City Comprehensive Plans for sanitary sewer and water main needs for the study area. Based on the changes in proposed land use, the traffic study requires revisions. The storm water requirements, along with the sanitary sewer and water main needs, are unchanged as a result of the revised land uses. The following paragraphs relate key findings of the traffic analysis. The complete analysis is included in Appendix B of this report. a. Traffic Analysis Update The traffic analysis was completed to determine required lane geometry for Bunker Lake Boulevard and Puma Street, along with turn lane requirements at four intersections in the study area. The revised land uses result in an increase of 18,100 trips per day into and out of the area at full build. This is at the low end of the range previously calculated for the area (18,500 to 23,300). Note: Short term improvements are intended to mitigate current safety or operations problems, along with full development of the Study Area. Mid-term improvements are anticipated safety related improvements that may be required within the study area. Long-term improvements are anticipated safety improvements required as a result of growth in the region. b. Short Term Improvements • Armstrong Boulevard & Bunker Lake Boulevard: o Bunker Lake Boulevard is proposed to be reconstructed in the near future by Anoka County to a four lane divided road between Ramsey Boulevard and Armstrong Boulevard. The dual southbound left turn lanes at this intersection will be striped when Bunker Lake Boulevard is reconstructed. A southbound double left turn lane will help reduce queues entering the COR development. o Plan for eastbound dual -right turn lanes, two eastbound through lanes, and a 300 ft. left turn lane. • Bunker Lake Boulevard (west of Armstrong Boulevard): o Expand to a four lane section for development to the first full access to the west of Armstrong Boulevard. This will be between 540 ft. to 775 ft., depending on access from the COR to Bunker Lake Boulevard. Prepared by: Bolton & Menk, Inc. Future Business Park —City of Ramsey Page 5
