Plan to replace beach sand, build ‘living shorelines’ adopted by LA County supervisors

Climate change produces more violent storms and bigger waves that increase beach erosion

To remedy the impacts of climate change on local beaches, the Los Angeles County Board of Supervisors voted to create a coastal resiliency plan on Tuesday, Nov. 7.

The plan calls for reusing sediment that is scooped out of flood control channels, mountain river dams and harbors to augment some of the 18 L.A. County beaches that have grown narrower due to loss of sand. It also calls for creating hybrid shoreline devices that combine manmade materials with natural elements to lessen the impact of waves that cause erosion.

According to the California Regional Assessment National Shoreline Management Study in 2018, Southern California’s ocean economy in 2013 was valued at about $27 billion. L.A. County’s ocean-related tourism and recreation industries generated more than $2.2 billion in 2020.

“The county’s beaches are more than just cultural touchstones: They provide a critical public resource to residents seeking respite from extreme heat, access to the water and nature, and recreational opportunities,” the motion reads.

Every year about 70 million people visit the county’s beaches, which stretch more than 75 miles from Malibu to Redondo Beach to San Pedro.

“Many residents and children in my district have never been to the beach,” said First District Supervisor Hilda Solis. “Everything we do to help preserve that shoreline and access for the public is of paramount importance.”
