Orange County officials have formally launched a new regional effort aimed at stabilizing and restoring South County’s increasingly eroded beaches.
Last week, the Orange County Board of Supervisors approved the formation of the South County Beach Coalition, a multi-agency collaboration designed to coordinate sediment management, streamline permitting and develop a long-term sand maintenance strategy for the region’s coastline. The initiative revives recommendations first outlined in the county’s 2013 OC Regional Sediment Management Plan, which identified the need for coordinated action but was never fully implemented.
More than a decade later, erosion has intensified along several South County beaches. Capistrano Park Beach, once considered wide and healthy, has suffered significant storm damage in recent years, with high tides and heavy winter surf destroying infrastructure and dramatically narrowing usable sand space. Beaches such as Doheny and other stretches in southern Orange County have also experienced ongoing sand loss.
County officials say the coalition will assemble technical experts, pursue funding opportunities and advocate for system redesigns that improve how sand is delivered and retained along the coast. The goal is to create a sustainable sand management plan that becomes part of the county’s routine infrastructure planning process.
A key component of the effort includes partnering with UC Irvine researchers to evaluate whether sediment trapped inland — particularly at Prado Dam — could be transported to the coastline. Feasibility discussions are exploring potential methods such as rail, pipeline or truck transport. County leaders have already convened meetings with regional agencies to examine logistics and regulatory challenges.
The coalition also aims to address historic sediment flow disruptions linked to coastal infrastructure. When Dana Point Harbor was constructed in the 1960s, plans reportedly called for annual sand delivery to nearby Doheny State Beach. That replenishment was not consistently maintained, contributing to long-term erosion patterns.
Beyond engineering solutions, the coalition is expected to evaluate “nature-based” approaches, including dune restoration and offshore habitat projects that enhance shoreline resilience. County leaders also plan to revive the long-dormant “State of the Coast” report to provide updated data and improved transparency on beach conditions.
For the maritime industry, coordinated sediment planning carries direct implications. Sand movement affects harbor entrances, navigation channels and dredging needs, while shoreline erosion can threaten waterfront infrastructure and recreational access. A unified regional strategy could improve predictability for harbor operators, marina managers and coastal businesses that depend on stable beaches and safe access.
County officials emphasize that beaches should be treated as critical infrastructure — assets that support tourism, recreation and the broader coastal economy. The South County Beach Coalition will now begin developing recommendations and is expected to report back to the Board of Supervisors with proposed actions and long-term planning strategies aimed at protecting one of Southern California’s most valuable coastal resources.
