Project Information

The Orange County Flood Control District (OCFCD) is proposing to improve the East Garden Grove - Wintersburg (C05) channel levees from Bolsa Chica Tide Gates to Warner Avenue, approximately 2 miles in length. The subject channel is located partially in unincorporated Orange County and in the City of Huntington Beach. The project location is currently the most "at risk" portion of the C05 Channel for catastrophic levee failure and was the site of a declared emergency on October 16, 2007

Details:

The improvements begin at the Tide Gates located at Bolsa Chica Wetlands area and end upstream of Warner Avenue. The improvements include constructing soil-mixed with cement columns sandwiched between two rows of steel sheet piles along both sides of the channel between Graham Street and Warner Avenue, and along the south levee only, from 2,000 feet downstream of Graham Street to Graham Street; and excavating the earthen embankment to widen the channel and increase the channel flood conveyance capacity. In addition, a single steel pile wall will be inserted from Bates Circle to 3,400 feet downstream of Graham Street (Oil Road Bridge) for levee toe reinforcement. Additional work includes slope repairs on critical locations downstream of Bates Circle and recreational trail and ramp construction for the general public's access to the Bolsa Chica trail network and the Wetlands area.
