Document Description
NOTE: Document is a Supplemental EA that is an amendment to the SEIS/EIR. The Santa Ana River is an approximately 100 mile long waterway that runs from the San Bernardino Mountains to Huntington Beach in Southern California. The Lower Santa Ana River runs from Prado Dam, in Riverside County, to its terminus approximately 30 miles downstream, at Huntington Beach. Ongoing and future construction that includes the raising of Prado Dam will allow for releases from the dam between 10,000 and 30,000 cubic feet per second (cfs). Planned elements associated with the raising of Prado Dam include several protective dikes and bank protections/stabilizations for portions of the Lower Santa Ana River. These structures will provide protection for areas of the Lower Santa Ana River that would otherwise be affected by these higher releases from Prado Dam. This EA focuses on the design changes to the embankment that will protect the Green River Mobile Home Park (GRMHP) from the 2001 Prado Basin and Vicinity SEIS/EIR. Changes from the 2001 document include the alteration of staging areas, access roads, and easement areas. The project area is located adjacent to the Santa Ana River, in Riverside County.
