The Information & Science Behind SOS

The U.S. Army Corps of Engineers (USACE) has officially released the Draft Integrated Report for the San Diego County Shoreline (Oceanside) Mitigation Study , marking a historic milestone for Oceanside. This federal initiative is one of several critical projects currently working to address the persistent erosion caused by the 1942 construction of Camp Pendleton Harbor. The Tentatively Selected Plan (Alternative 1) proposes a 50-year commitment of recurring beach sand nourishment every 10 years of over 1 million cubic yards of sand each cycle. This sand will be placed on our beaches along the Oceanside coastline, from just South of the pier to the Buena Vista Lagoon. Save Oceanside Sand played a pivotal role in the development of the final proposed TSP. SOS’s persistent and direct engagement with Oceanside city staff, Congressman Mike Levin and the USACE Los Angeles district office regarding the significant impacts of the Camp Pendleton Boat Basin on sand transport and erosion along the entire Oceanside shoreline was vital in helping this come to fruition. Throughout the study process, SOS tirelessly advocated for recognition of the Oceanside coastal sand loss on its entire coastline. By bringing community concerns, local knowledge, and supporting science directly to federal decision-makers, SOS helped ensure that harbor-induced erosion impacts extend all the way to the Buena Vista Lagoon, ensuring the entire southern stretch was included in the federal restoration vision. This federal plan is designed to complement and integrate with other local efforts such as Oceanside’s RE:BEACH Pilot Project of nourishment and retention and SANDAG Regional Beach Sand Project III which will also bring sand nourishment to our shore. All three projects will be coordinated together to restore our beaches for generations to come! Want to learn more? The Army Corps of Engineers will hold a virtual meeting on Tuesday, June 16, 2026, from 5:30 to 7:30 p.m . to present the project information and provide an opportunity for comments. Details here .
