Project Understanding I In accordance with the Comprehensive Plan, an 18 -inch sanitary sewer was be extended westward in Bunker Lake Boulevard a distance of approximately 2,750 I feet. This line will provide service to the study area, as well as future development that may occur on the south side of Bunker Lake Boulevard, and could be further extended in accordance with the Comprehensive Plan. V:a _ The image to the left (from the City's 2012 Comprehensive Sanitary sewer Study) depicts 18 -inch trunk sanitary sewer extended to west of Armstrong Boulevard through the study area. Water Distribution and Supply Improvements b Watermain was extended across Armstrong Boulevard from the main on the east side of Armstrong. From there, the watermain was further extended westward in Bunker Lake Boulevard, a distance of approximately 2,750 feet. --- , It was then planned to extend this trunk watermain west to Puma Street and north to Alpine Drive via Puma Street to provide future looping and provide water to unserviced areas and future developments. Loops within the development will then 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. This future watermain corridor should be evaluated with the current analysis. The image to the left (from the City's 2012 Comprehensive Water System Study) depicts trunk water facilities extended to west of Armstrong Boulevard through the study area. 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. Our understanding is that 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. Future Business Park RFQ I City of Ramsey, Minnesota
