Abstract:

Marine Corps Base MCB Camp Pendleton and Marine Corps Air Station MCAS Camp Pendleton maintain and operate facilities and provide services to support operations of aviation activities and units of operational forces of the United States Marine Corps USMC. MCB Camp Pendleton is the USMCs only west coast military installation where a comprehensive air, sea, and ground assault training scenario can be executed. Facilities and operations in the southern portion of MCB Camp Pendleton adjacent to the Santa Margarita River are located in the 100-year floodplain for the river. Heavy rainfall in 1993 resulted in the flooding of MCAS Camp Pendleton, portions of MCB Camp Pendleton and the destruction of Basilone Road Bridge. The readiness and ability to support the missions of MCB Camp Pendleton and MCAS Camp Pendleton were seriously jeopardized because of the flooding and resulting damage. The flood damage caused operations to cease in the flood damaged areas and reduced the ability of the installation to perform the required missions for a period of 7 months. The flooding threatened the safety of personnel working in a portion of MCB Camp Pendleton and MCAS Camp Pendleton. The flooding also damaged structures and facilities, including buildings in the historic Santa Margarita Ranch House complex, structures in the Chappo 22 Area, and Sewage Treatment Plant STP No. 3. To prevent future damage to property and disruption of essential operations, the MCB Camp Pendleton has proposed construction of a flood control project.
