Document Description
The proposed action involves repairing 3,700 feet of the existing Bradley Canyon Levee with sheet pile and soil cement of which approximately 1,000 feet of sheet pile would be installed in areas supporting riparian habitat and the remaining 2,700 feet would be repaired using soil cement. This Draft SEA/MND is a supplement to the Final Environmental Assessment/MND, August 2009) for the repair of 6.5 miles of the Santa Maria River Levee. Rational: The Corps recently performed an additional hydraulic analysis on the Santa Maria River Levee System. The hydraulic analysis indicated that, should a breach occur along the upstream Santa Maria River Levee during a high flow event, flows proceeding through the breach would attack the Bradley Canyon Levee and possibly overwhelm the levee and cause it to fail.
