Construction Updates

Materials Delivery

Daytime truck deliveries via Linda Lane are expected to continue to support ongoing construction of the Verdura wall. Residents and businesses should anticipate daily truck activity for approximately two weeks.

Catchment and Verdura Wall

Crews are continuing work to construct the 1,400-foot catchment wall, including drainage installation, rebar placement and shotcrete operations. Construction of the Verdura wall to support the new San Clemente Beach Trail is also underway and is expected to continue through April.

In the coming weeks, crews are expected to begin work on the access bridge at Mariposa Channel. Activities will include excavation, drilling and grading to remove the bridge.

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. 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.
