Coastal Rail Emergency Projects
Coastal Rail Emergency Project – Area 3
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 work hours are Monday through Saturday from 6 a.m. to 10 p.m.
The schedule is subject to change due to inclement weather or unforeseen operational issues.
Construction Activities Update
The 1,400-foot permanent catchment wall is beginning to take shape as crews are expected to continue applying architectural shotcrete, giving the wall its finished textured appearance. This work is anticipated to finish by mid-June. Meanwhile, crews continue to work on the foundation for an access bridge at the Mariposa Channel.
This work may be loud. The schedule is subject to change due to inclement weather or unforeseen operational issues.

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.

Beach Access
The Mariposa underpass is closed. Beach access at Dije Court and El Portal are temporarily closed to ensure the safety of the public. The public can still access the beach using the El Portal beach underpass and the Linda Lane beach underpass.

Staging Areas
Contractors are staging equipment and materials in the North Beach parking lot and on a city-owned vacant lot at the corner of Avenida Estacion and Calle Deshecha. Several parking spaces along Linda Lane will also be utilized for construction vehicle parking on a first-come, first-served basis.
