Design Notes: Center Street — For the analysis, the existing Center Street configuration (south of Ramsey Parkway) was used for that section of roadway. Between Ramsey Parkway and Bunker Lake Boulevard, a parkway section was used per The COR Framework plan. Xenolith Street — The COR Design Framework plan depicts the section as 50 ft face-to-face, 6 ft boulevards, and 10 ft walks. Yolite Street — The COR Design Framework plan depicts the section as 36 ft face-to-face, 6 ft boulevards, and 10 ft walks. This is a local Street, bordering on Subdistricts 1 and 2a. Zeolite Street - The COR Design Framework plan depicts this roadway as a Connector street. Within The COR, Rhinestone Street, Zeolite Street and Veterans Drive (between Rhinestone Street and Zeolite Street) are considered Connector Streets. Our analysis matches the previously constructed Rhinstone Street cross section, which consists of a 40 ft face-to-face street section with 6 ft boulevards, and 6 ft walks. Veterans Drive - The COR Design Framework plan depicts this roadway as a Local street, located within Subdistrict 3, and requiring 6 ft boulevards and 10 ft walks. Peridot Street - The COR Design Framework plan depicts this roadway as a Local street, located within Subdistrict 3, and requiring 6 ft boulevards and 10 ft walks. Bunker Lake Boulevard — The Anoka County 2030 Comprehensive plan identifies this roadway as a 4- lane, divided highway. V11. ADDITIONAL PUBLIC INFRASTRUCTURE ANALYSIS As a portion of this analysis, we reviewed the City Comprehensive Plans for sanitary sewer and water main needs. The following is a summary of results for the various analyses and reviews. Sanitary Sewer The segment of trunk sanitary sewer main following the currently platted Ramsey Parkway does not follow the revised 2012 master plan alignment. This main may need to be realigned when this segment of Ramsey Parkway is constructed. An 8-inch gravity sanitary sewer main will be adequate to convey flows from the area. For this analysis, we included an allowance for 8-inch service lines to be extended to properties along the corridors. Water Main Ramsey Parkway includes a 12-inch watermain, which completes an east -west trunk system through The COR. All existing streets include provisions to extend 8-inch watermain into the study area. Future roadway construction (other than Ramsey Parkway) should include 8-inch watermain to complete looping in the study area. In the case that a high water user plans to develop within the project area, additional flow analysis should be performed to verify they will have adequate flow and pressure for their individual needs. Figure 8 in Appendix B depicts watermain and Figure 9 depicts the sanitary sewer improvements within the study area. Prepared by: Bolton & Menk, Inc.
