Title
East Side Dike Improvement Project
Description
The Coachella Valley Water District (CVWD) intends to certify the East Side Dike, from Dune Palms Road to Interstate 10 (I-10), with the Federal Emergency Management Agency (FEMA) as a flood protection structure. CVWD previously completed hydraulic and scour analyses, and geotechnical investigation for the East Side Dike. The results obtained from the studies indicate that the western end of the East Side Dike adjacent to the Talavera Development is susceptible to erosion, In order to accredit a levee, FEMA requires that no appreciable erosion would occur during the 100-year flood (44 CFR 65.10). The definition of "appreciable erosion" is generally accepted to mean that any erosion that occurs would not threaten the stability of the levee. For the East Side Dike, erosion or loss of the levee embankment can occur from the removal of sediments from the waterside slope of the embankment by high velocities and by scour near the toe of the embankment, loss of support, and failure of part of the embankment slope.
