Crews made significant progress this week in stabilizing San Clemente’s coastal rail line, which is expected to remain closed for another five weeks as emergency repairs continue.
Focusing on the most vulnerable areas in San Clemente, crews are working to reinforce the coastal rail line and protect against sliding bluffs and coastal erosion. The work began April 28.
Rail is expected to be shut down for passenger service for a total of approximately six weeks, through early June.
The Orange County Transportation Authority, in coordination with Metrolink and Amtrak’s Pacific Surfliner, is taking action to protect the only coastal rail link between San Diego and Orange counties. Threats continue from the privately owned bluffs as well as from coastal erosion and storm surges.
Map of zones for OCTA emergency repairs to coastal rail line, (Photo courtesy of OCTA)Significant progress has been made on repairs of riprap – a layer of large rocks to protect against soil erosion – in one of four zones being worked on, Area 1.The bulk of this week’s work consisted of removing the remaining spans of the city’s damaged Mariposa Point pedestrian bridge in Area 3. Each steel span is approximately 80 feet long and weighed 20,000 pounds.
Excavators were positioned on the beach and the inland side of the track to begin repairing the damaged riprap. That work will continue in Areas 1 and 2 through the weekend and throughout next week, typically between 5 a.m. and 8 p.m.
At the same time, the OCTA is working to source 240,000 cubic yards of sand set to be placed in Areas 1 and 2 north of Mariposa Point.
At its May 7 meeting, the California Coastal Commission will consider OCTA’s proposal to construct a new catchment wall at Mariposa Point in Area 3 and restore the pedestrian beach trail.
Throughout the past four years, the eroding bluffs on San Clemente’s coastline – on both city and private property – have repeatedly forced the closure of the rail line that has operated largely uninterrupted for over 125 years.
OCTA submitted an emergency Coastal Development Permit application to the Coastal Commission that was partially approved in April. The total package of projects, estimated at a cost of approximately $300 million, includes about 95% sand and 5% rock reinforcement.
The current work, estimated to cost approximately $10 million, is moving forward under emergency authorization from the commission.
During the closure, passengers are asked to check metrolinktrains.com/service-updates and www.pacificsurfliner.com/alerts for the latest service updates.
