Coastal Commission approves seawall, sand for battered stretch of San Clemente

The California Coastal Commission voted Thursday to allow transportation authorities to build a quarter-mile-long seawall just south of San Clemente State Beach to protect the coastal railroad from rising sea levels and coastal erosion. The plan also includes a major influx of sand for local beaches.

Why this matters

The tracks that carry passengers on the Pacific Surfliner between Orange County and San Diego have shut down frequently in recent years due to rising sea levels and erosion. Rail authorities have dumped thousands of tons of boulders on the beach to buttress the tracks. Now, they’re hoping a seawall will buy them time to come up with a more permanent solution. Not everyone is happy about the plan. Critics say seawalls cause waves to refract and dig deeper, ultimately stripping away even more sand in the long run.

What else do I need to know?

Environmental groups and local tribal authorities say the emergency work has already ruined the beach. To mitigate the negative effects, authorities will haul in close to 700,000 cubic yards of new sand to San Clemente beaches over the coming year.

What's the official reaction?

Orange County Supervisor Katrina Foley released a statement hailing the decision. “Today’s unanimous approval from the California Coastal Commission marks a major milestone to save our critical coastal rail corridor and restore San Clemente’s iconic beaches following decades of erosion and inaction,” Foley said. “The placement of 690,000 cubic yards of sand represents the region’s largest beach nourishment effort in decades and demonstrates our commitment to long-term coastal resilience."

She added: “Wide sandy beaches provide a natural buffer for our rail corridor while protecting our coastline, expanding public access, and supporting our local economy. Through continued collaboration with our state, regional, and local partners, we will advance lasting solutions that protect our beaches and preserve this vital transportation corridor for future generations.”
