Metrolink rail service in Orange County and San Diego County has faced repeated disruptions due to coastal erosion and weather-related damage. In mid-August, service between Laguna Niguel/Mission Viejo and Oceanside was suspended through August 14 due to forecasted high tides and strong surf. This followed previous track erosion and communication system damage caused by swells in late July. To stabilize the tracks, maintenance crews have been deploying riprap, or large rocks, to prevent further erosion. While intended to protect the rail line, some local advocates have expressed concerns that the placement of these rocks may interfere with natural sand accumulation and contribute to coastal erosion. In early September, Hurricane Tropical Storm Marie generated powerful swells and heavy rainfall that caused significant infrastructure damage across the Southern California coast. In San Clemente, the coastal rail corridor used by Metrolink and Amtrak’s Pacific Surfliner has been suspended between Laguna Niguel/Mission Viejo and Oceanside. Emergency crews are working to stabilize the tracks using riprap to combat erosion and high tide damage, riprap, while Amtrak utilizes buses to transport passengers during the disruption. passengers. Beyond the rail corridor, the storm caused widespread flooding in areas such as Seal Beach and Long Beach. property damage. In Long Beach, intense waves breached seawalls and sand berms, leading to berms on the Long Beach Peninsula, prompting the mandatory evacuation of approximately 20 homes due to concerns over structural integrity and cracked concrete. Local authorities also issued health advisories regarding ocean water runoff. Coastal authorities in Los Angeles County reported a surge in water rescues, with projections reaching over 1,000 during 15-foot erosion drop from the holiday weekend. A Coastal Flood Advisory remains boardwalk. In Malibu, heavy swells caused a driveway collapse and a natural gas line rupture, resulting in effect through Tuesday night. By September 8, the impact of Tropical Storm Marie expanded. five residences being red-tagged. In Orange County, Dana Point, at least 14 homes in Dana Point were damaged, with approximately 12 being red-tagged as uninhabitable. While Marie has transitioned into a post-tropical cyclone, authorities warn that dangerous surf and rip currents will persist, and NOAA predicts a 50% to 60% chance of above-average rainfall through mid-September.
