The SFPUC proposes to replace and upgrade water mains along San Bruno Avenue from Campbell Avenue to Mansell Street and along Blanken Avenue from Tunnel Avenue to Executive Park Boulevard. New water mains would be installed as close as possible to the existing alignments but would not be in the same trench footprint as the existing lines because the existing lines must remain in service until the new lines are installed. Typically, the new water main alignment would be located 5 feet from the curb face or 3 feet from the concrete parking strip where feasible, based on street occupancy by other utility lines. The new 6-inch and 8-inch water mains would be constructed of DIP and would replace existing cast iron pipe (CIP). The new 16-inch water main would be constructed of DIP. The proposed Project would include a total of approximately 12,934 linear feet (2.4 miles) of water main replacement and installation
