Sanitary Sewer Improvements In 2004, a 30-inch trunk sanitary sewer was extended along Sunwood Drive to serve the COR. In 2005, 15-inch and 18-inch sanitary sewer was installed from Bunker Lake Boulevard to Sunwood Drive. This main was installed in Zeolite Street from Bunker Lake Boulevard to the currently platted Ramsey Parkway. This main then followed the un-platted Yolite Street alignment to Sunwood Drive. The segment of sanitary sewer main that follows the platted Ramsey Parkway does not follow the revised 2012 master plan alignment of Ramsey Parkway. This main may need to be realigned when this segment of Ramsey Parkway is constructed. The existing sanitary sewer trunk mains adjacent to the study area have capacity to provide service to the study area. Water Distribution and Supply Improvements 12-inch Watermain has been installed in all three streets adjacent to the study area (Sunwood Drive, Center Street, and Zeolite Street). All of the trunk mains installed included provisions for service to the study area in the form of 8-inch lateral watermain services. 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 serve the study area. Storm Water Management A storm sewer system was previously constructed in Sunwood Drive and Center Street NW. The system directed roadway runoff to regional ponds located to the east and south of the study area. A storm sewer system comprised of 33-inch to 42-inch has been installed directly north of the study area in what was previously named West Town Center Drive. The planned roadway alignment was revised in the 2012 COR master plan, and a portion of the constructed storm sewer system lies within the boundaries of the regional pond. When the pond is constructed, a portion of this storm sewer will most likely be removed. Drainage for the study area is planned to flow north from Sunwood Drive and west from Center Street to a regional pond located north of Ramsey Parkway and west of Center Street. The outlet for the regional pond currently discharges to an open area located on the south side of the future Ramsey Parkway. The storm water then flows overland to a pipe near the Sunwood Drive and Yolite Street intersection. The pond outlet is anticipated to ultimately include a discharge pipe from the regional pond to the Sunwood Drive storm sewer. This pipe will most likely be extended along the future Yolite Street. We assume the regional pond will be constructed in phases as properties develop. No cost analysis was performed related to construction of the pond. Prepared by: Bolton & Menk, Inc.
