Title

Serra Drive Outfall Repair Project

Description

The Serra Drive Outfall Repair Project would include the repair of an existing concrete pipe storm drain and headwall behind two private residences along San Pedro Creek. Project components include the removal of the existing damaged headwall, high density polyethylene pipe (HDPE), and spillway and construction of a new concrete headwall, wingwall, and partially grouted rock rip-rap energy dissipater. The rip-rap energy dissipater would be 7.5 feet wide and located approximately 5 feet downstream of the concrete headwall apron to the toe of the embankment. Four feet of riprap extends into the creek bed to prevent erosion at the toe of the embankment. It would be partially grouted to provide appropriate energy dissipation prior to flows from the storm drainpipe reaching the creek.
