The flood control system surrounding the Natomas Basin is part of the Sacramento River Flood Control Project (SRFCP), an integrated system of levee-protected basins. The original design of the SRFCP anticipated that area basins will be protected by levees that are at least high enough to contain flood waters comparable to those produced by the floods of 1907 and 1909. The flood water elevations designated for each basin in the system were specified in a design memorandum issued by the U.S. Army Corps of Engineers (USACE) in 1957. This design calls for the height of levees to be set at the designated water surface elevation (“1957 profile”) plus at least three feet of freeboard along the Sacramento River to address hydrologic and engineering uncertainty and contain wind-driven waves.
The Natomas Basin is the northern growth area of the Sacramento metropolitan area and currently has both agricultural and, increasingly, urban uses. The Sacramento International Airport is in the Natomas Basin. A substantial number of residents and damageable property, as well as, significant regional infrastructure in the basin, are protected from flooding by an extensive system of levees jointly managed by federal, state, regional (SAFCA), and local agencies.
BRI acts as the Right of Way Manager for Sacramento Area Flood Control Agency (SAFCA) for the project. SAFCA is a joint powers agency with the City of Sacramento, the County of Sacramento, the County of Sutter, the American River Flood Control District and Reclamation District 1000. The ROW program includes acquisitions for over 300 parcels.
BRI provides the following services: Right of Way Planning including coordination with multiple property owners; ongoing meetings with local agency staff; and ongoing involvement with Capitol Corridor management.
