Document Description
The City proposes to replace three 48-inch culverts in the City’s Outfall Channel with a single cast-in-place concrete culvert with four bays to accommodate projected buildout storm drainage flows of 1,443 cubic feet per second (cfs). The cast-in-place culvert will be approximately 115 feet long, 31 feet wide, and 8 feet tall with four 6-foot by 6-foot bays. Cast-in-place concrete headwalls will be constructed at the inlet and outfall structures. The individual bays will be fitted with flap gates at the outfall structure to prevent backflow from the Bypass and will include a gate shaft equipped with emergency isolation slide gates to enable the culverts to be completely sealed in the event of flap gate failure.
