Inland Slope Rehabilitation Project
OCTA in coordination with Metrolink, is rehabilitating the slope along the railroad in the Cities of Lake Forest, Mission Viejo, and Laguna Niguel. The project will maintain safety and reliability of the railroad infrastructure.
Within OCTA-owned right of way, there are six locations along the railroad experiencing erosion on sloped areas, which pose potential risks to the railroad’s structural integrity. To address this issue, potential remediation strategies include the application of shotcrete to stabilize the slope and ensure long-term stability. Click on the drop-down menu to learn more about the work and respective timelines for each area.
Construction is expected to begin in mid-April and all six areas are anticipated to be completed in Summer 2026. Work hours are Monday through Friday from 6 a.m. to 4 p.m.
Crews are beginning work to rehabilitate the slope in three areas along the rail right of way in Lake Forest.
- Areas 1 and 2: Expected to begin as early as Monday, April 13 for approximately four weeks
- Area 3: Expected to begin as early as Monday, April 27 for approximately six weeks
Area 2 Ridge Route Drive Detour
Crews are set to remove vegetation and apply concrete to the slope adjacent to the Ridge Route Drive tunnel. This will require both directions of Ridge Route Drive between Jeronimo Road and Overlake to close during work hours for approximately two weeks, beginning as early as Monday, April 27.
The pedestrian tunnel is expected to be closed for approximately four days and reopened at the end of the workday. Dates of the closures are still yet to be determined.
