Powerful surf and elevated tides associated with Tropical Storm Rachel damaged homes and public infrastructure along Southern California’s coast over the October 10-11 weekend. The historic boardwalk on the Long Beach Peninsula suffered extensive damage, while officials continued to warn of flooding, erosion and dangerous ocean conditions after the storm weakened.
Key Takeaways
- Waves damaged homes and a historic boardwalk on the Long Beach Peninsula
- Rachel’s remnants also brought flooding and debris flows to the Coachella Valley
- Coastal flood advisories extended from San Diego to San Luis Obispo
- High tides, beach erosion and rip currents remained concerns after the strongest surf
- Newport Beach officials said protective sand berms helped limit residential damage
Tropical Storm Rachel Brings High Surf to Southern California
Rachel weakened before reaching Mexico’s Baja California coast, but its swells struck Southern California beaches already affected by storms earlier in the season. High tides and powerful waves overwhelmed parts of the shoreline, sending water into streets and oceanfront properties.
Farther inland, rainfall and runoff from Rachel’s remnants caused flooding in the Coachella Valley. The event came as the state prepared flood rescue equipment upgrades for specialized swiftwater teams ahead of the winter storm season.
Long Beach Homes and Boardwalk Sustain Coastal Damage
On the Long Beach Peninsula, waves breached the protective bulkhead and tore away sections of the historic Seaside Walk boardwalk. Floodwater entered nearby homes and streets, prompting evacuations and safety inspections. Officials marked multiple properties unsafe to enter.
City crews reinforced vulnerable sections of the waterfront with sandbags and undertook repairs when tides allowed. The damage left questions about the condition of the boardwalk, the bulkhead and neighboring buildings that will need to be resolved through inspections and repair work.
High Tides and Large Waves Extend Coastal Safety Risks
Preliminary readings near Long Beach placed the Sunday, October 11, morning tide at approximately 7.6 feet. Forecasters expected morning high tides of about 7.5 feet on Monday and Tuesday, prolonging the risk of water reaching low-lying beaches, pathways and parking areas.
Coastal flood advisories covered areas from San Diego through San Luis Obispo, although exposure differed by location. Officials also warned of strong rip currents, continued beach erosion and large waves that could make shoreline access hazardous even after Rachel’s most intense impacts passed.
Protective Berms Help Limit Damage in Newport Beach
Newport Beach officials reported that reinforced sand berms helped protect residential areas, despite flooding along parts of the Balboa Peninsula. The city had declared a local emergency and mobilized crews to rebuild and strengthen barriers as elevated surf and water levels persisted.
Officials asked residents and visitors to stay off the berms and observe temporary access restrictions. The response comes as communities consider California’s winter flood risks under a strengthening El Niño pattern.
Berms can reduce direct wave exposure, but their effectiveness depends on location, upkeep and storm conditions. Newport Beach’s experience does not mean the same measures would provide equal protection on every stretch of coast.
Coastal Repairs and Public Access Remain Priorities
Long Beach faces inspections and repair decisions involving the damaged boardwalk, bulkhead and nearby homes. The available reports had not established a final repair cost or schedule. Newport Beach, meanwhile, continued monitoring protective barriers and access points after the flooding.
The end of the storm’s strongest effects did not immediately make affected shorelines safe. Beachgoers and residents should follow posted closures, local officials’ instructions and updated coastal hazard advisories while high surf and dangerous currents persist.
