Project Details

The Coastal Rail Emergency Project – Area 3 is constructing a 1,400-foot-long catchment wall on the bluff side of the tracks at Mariposa Point. The wall will extend from the El Portal Beach access point to Linda Lane. The San Clemente Pedestrian Beach Trail will also be restored as part of this project.

Construction Updates

Construction Activities

Crews have completed installation of the wood lagging panels for the catchment wall and are continuing with drainage work and shotcrete operations. Construction of the verdura wall to support the new San Clemente Beach Trail is also underway and expected to continue through May.

In the coming weeks, crews are expected to begin work on the access bridge at Mariposa Channel. Activities are anticipated to begin mid-April and include removal of the current bridge and grading.

Daytime intermittent deliveries via truck through North Beach and Linda Lane are expected to take place as needed to support these activities.

San Clemente Beach Trail

The San Clemente Beach Trail will be closed from the North Beach parking lot to El Portal during work hours but will reopen at the end of each workday and will be open on Sundays. The trail will be closed from El Portal to Linda Lane until project completion.

As part of the Coastal Rail Emergency Project, the San Clemente Beach Trail is being restored and is expected to reopen to the public upon project completion in Summer 2026. For additional information about the trail improvements and project features, check out our Trail Benefits Flyer.
