Puma Street to provide future looping and provide water to unserviced areas and future developments. Loops within future development would be utilized to promote reliability and functional flexibility as well as promoting fresh water moving throughout the system. It was previously determined that the elevated storage for the City of Ramsey is adequate to provide fire flow to the study area. The distribution system was also found to be adequate to move the water from the City's three towers to the study area. Additional Consideration: The right-of-way of Bunker Lake Boulevard could be utilized for a future route of a 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. Because the exact location of the intake and raw watermain alignment had not yet been determined, no provisions were made during the previous improvements. Storm Water Management Drainage for the study area is essentially sheet flow to the center of the site to existing wetlands, and then easterly through the wetlands and through a culvert under Armstrong Boulevard. Runoff continues to flow into the actively developing COR area. A storm sewer system was installed in Bunker Lake Boulevard to manage the storm water runoff within the right-of-way. We anticipate that this included considerations for the future widening and extension of Bunker Lake Boulevard as well. Extensive hydraulic modeling was refined and detail added to represent preliminary storm water management conditions for future development scenarios. ADDITIONAL ANALYSIS As a portion of this analysis, we completed traffic and storm water studies and reviewed City Comprehensive Plans for sanitary sewer and water main needs for the study area. The traffic study is included as Appendix B and the storm water study is included as Appendix C to this report. The following is a summary of results for the various analyses and reviews. Traffic Analysis 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 Future Business Park development is proposed north of Trunk Highway (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 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 18,500 to 23,300 trips per day into and out of the area at full build. Prepared by: Bolton & Menk, Inc.
