Document Description
NOTE: FONSI / Supplemental EA The Auxiliary Dike and Floodwall Project is part of the Prado Basin flood control improvements under the Santa Ana River Mainstream Project (SARP). The project analyzed and approved in the 1988 Phase II General Design Memorandom (GDM)/Supplemental Environmental Impact Statement (SEIS) and 2001 Final SEIS/Environmental Impact Report (EIR). The Auxiliary Dike and Floodwall Project would be constructed in the same fashion as the approved Auxiliary Dike; however, the design alignment would be slightly modified to reduce impacts to riparian and coastal sage scrub vegetation. The main objective of this project would be the same as the approved Auxiliary Dike project, which is to provide flood protection for the SR 91 Riverside freeway and to protect the lives and properties (homes and businesses) of individuals residing in the project area.
