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.

Construction began in May 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.
This work may be loud. Train horns may sound when railroad workers are present in the rail right of way. The schedule is subject to change due to inclement weather or unforeseen operational issues.
Crews are working to rehabilitate the slope in three areas along the rail right of way in Lake Forest.
- Areas 1 and 2: Crews completed shotcrete operations and are expected to return for final checklist items in the coming weeks.
- Area 3: Work is continuing through July.
Crews are working to construct a drainage channel and rehabilitate the slope along the rail right of way in Laguna Niguel. Mobilization began in late May with activities expected to continue for approximately two months.
Concrete pours to construct the drainage channel are scheduled to begin in early July for approximately three weeks. Concrete trucks are expected to enter and exit the work area via Getty Drive. A flagger will be onsite to moderate traffic.
Crews are working to rehabilitate the slope along two areas along the rail right of way in Mission Viejo.
Construction began in June and is expected to continue for approximately six weeks.
