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 7 a.m. to 7 p.m.

The schedule is subject to change due to inclement weather or unforeseen operational issues.

Construction Updates

Shoring Wall

Crews are expected to continue working south of Mariposa, constructing a temporary shoring wall, which will allow crews to safely access the site and construct the catchment. Construction activities include drilling soil nails, also more commonly known as steel bars, as well as applying shotcrete.

Catchment Wall

Approximately 220 steel beams and rebar cages are scheduled to arrive on-site beginning as early as Sunday, Dec. 14 and continuing through March 2026. These materials will play a critical role in building the 1,400-foot-long catchment wall. This activity is expected to occur during daytime and nighttime hours over the next several months.

• Nighttime Deliveries via rail will take place on Sunday and Monday nights, from 11 p.m. to 5 a.m. Materials will be staged at the project site.
• Daytime Deliveries via truck will take place Monday through Saturday, from 7 a.m. to 7 p.m. Materials will be staged on a city-owned lot on the corner of Avenida Estacion and Calle Deshecha and subsequently moved to the project site on Wednesdays and Fridays, between 9 p.m. and 6 a.m.

This work may be loud. Residents may hear back-up alarms and noise from construction activities. The alarms are required by state regulations for employee safety on all construction equipment in use.

San Clemente Pedestrian Beach Trail

The San Clemente Pedestrian 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.

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.
