Document Description
Note: Review per lead & Addendum The 2001 SEIS/EIR had identified six distinct locations on the south and north banks of Reach 9 that required protection. However, the Lower Santa Ana Mainstem Project Design Documentation report dated November 2011 indicated the need to improve bank protection to additional areas within Reach 9. This SEA/EIR Addendum evaluates the environmental impacts associated with the reconstruction of an existing 1,600-foot long soil cement embankment structure located adjacent to SR 91, upstream of Gypsum Canyon Road. The reconstructed embankment would provide increased flood and scour protection to SR-91 and the Santa Ana River Interceptor pipeline which will relocated to the area between the existing levee embankment and SR 91.
