Crews from USACE contractor, Manson Construction, prepare to remove beach end of massive sand pipeline. The U.S. Army Corps of Engineers Los Angeles District began preparations for a 50-foot-wide beach nourishment project along a stretch of shoreline Nov. 21 in San Clemente. Sand placement operations are expected to begin Dec. 15. The Authorized Project calls for coastal storm damage reduction, which includes construction of a 50-foot-wide beach fill along a 3,412-foot-long stretch of shoreline, using 251,000 cubic yards of compatible sediment.
