At the southern end of the project, near San Clemente State Beach, 1,400 cubic yards of riprap repair, 22,000 cubic yards of engineered revetment, seawall or functionally equivalent structure, and 300,000 cubic yards of sand have been identified as necessary to protect the track.

The commission on Wednesday unanimously approved a request for a Coastal Development Permit to construct the catchment wall at Mariposa Point and restore the pedestrian trail. The 1,400-foot-long catchment wall will help protect the rail line from sliding debris from the privately owned hillside above the track. In San Clemente, crews pushing ahead with the emergency work finished clearing out ...

OCTA has updated its potential solutions to address immediate threats to rail service through San Clemente, and sand nourishment – always under consideration – is a key piece in the coastal rail protection puzzle. The updates come following multiple listening sessions, OCTA Board feedback, and other stakeholder input on OCTA’s Coastal Rail Resiliency Study – an effort to protect a ...

A critical component of the project includes a one-time infusion of approximately 540,000 cubic yards of sand for beach nourishment. OCTA is exploring viable offshore and inland sand sources to support erosion control measures.

Following a request from OCTA CEO Darrell Johnson, the California Transportation Commission (CTC) awarded $7.2 million to OCTA for a construction project to help restore a critical link in Southern California’s rail network. The new funding from the state allows the OCTA and Metrolink project team to move forward on constructing a catchment wall at Mariposa Point in San Clemente, as well as ...

OCTA’s first action was to issue a request for information for contractors to provide dredging and transport options to expedite the sand placement component of the projects. OCTA expects to place approximately 540,000 cubic yards of sand. Emergency action is necessary to prevent additional disruption of vital rail service.

This emergency stabilization effort builds on more than $313 million in secured state and federal funding, including grants from the Transit and Intercity Rail Capital Program, the SB 1 Trade Corridor Enhancement Program, and the federal CRISI program. The OCTA Board also amended its FY 2024-25 budget to allocate an additional $135 million to advance this work. Sand nourishment, while starting ...

The Coastal Rail Infrastructure Resiliency Project targets four locations within a 7-mile coastal section of the OCTA-owned Orange Subdivision. Work includes rock gradation installation, beach sand replenishment, and trail restoration.

The project components consist of 95% sand and 5% armoring. The current work in Areas 1 and 2, estimated to cost approximately $10 million, is underway, utilizing an emergency authorization from the California Coastal Commission.

An Initial Assessment conducted by OCTA identified urgent needs, which this current funding will support, including addressing four hot spots that could affect the rail line if not reinforced with additional measures such as sand, a catchment wall and rock revetment.
