LA County outlines $27 million living-shoreline plan and 300,000-cubic-yard beach nourishment for Redondo Beach

The Los Angeles County Department of Beaches and Harbors presented a living-shoreline demonstration project for Redondo Beach that would place about 300,000 cubic yards of beach-quality sand, create roughly 0.5 acre of dune habitat and widen the beach by about 90 feet, county staff said during the Harbor Commission meeting.

County coastal resilience project manager Emiko Innes said the project area lies between the Redondo Beach Pier and the Topaz groin and that county modeling shows most sediment near the beach is lost to the nearby Redondo Submarine Canyon rather than migrating north under the pier. “This will make the beach width 90 feet wider than current condition,” Innes said, describing the proposed nourishment envelope and the dune habitat element.

The county described the project cost as about $27,000,000 and staff cited a benefit–cost ratio of 7.5. Innes said the current feasibility study is expected to finish in July 2025 and that subsequent phases will include preliminary engineering, environmental review and permitting; graphic design and outreach; and coordination with the U.S. Army Corps of Engineers to pursue beneficial…
