The extension of the full Center Street typical section was completed to 100-feet north of 145' Avenue NW. The remaining roadway was then constructed as a temporary street section with bituminous curb and a bituminous trail for a distance of approximately 220-feet to Ramsey Parkway. Zeolite Street NW Zeolite Street was constructed as a temporary rural section with bituminous surface in 2005 from Sunwood Drive to Bunker Lake Boulevard. Bituminous Trails A 10-foot wide bituminous trail was constructed in the wide median of Ramsey Parkway east of Center Street. A continuation of the trail was also constructed along the west side of Center Street to allow for a connection to the 10-foot concrete walk near 145' Avenue NW. 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 Center Street serves as a watershed boundary within The COR area. Portions of The COR located east of Center Street are routed to a pond located near Ramsey Boulevard and the BNSF railroad tracks. Portions of The COR located west of Center Street are routed to a regional pond located north of Ramsey Parkway, just west of Center Street. The outlet from the regional pond is proposed to consist of storm water piping from the pond to an existing storm sewer located in Sunwood Drive at Yolite Street. While most of the study area is anticipated to flow north into the regional pond, two exceptions are anticipated: • The City park located adjacent to Center Street will most likely be routed to the Center Street storm sewer system and flow to the east.
