Inland Slope Rehabilitation Project

The Inland Slope Rehabilitation Project was completed in September 2026

Project Overview

Metrolink, in coordination with the Orange County Transportation Authority (OCTA), rehabilitated the slope in six areas along the railroad in the cities of Lake Forest, Mission Viejo, and Laguna Niguel. Slope rehabilitation was performed to address potential erosion risk and maintain the stability, safety and reliability of 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 is anticipated to be complete in September 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 have completed work in all three areas along the rail right of way in Lake Forest.

Crews are wrapping up construction activities within the rail right of way in Laguna Niguel. Work is anticipated to be complete as early as the week of Sept. 21.

Crews have completed the work in the two areas along the rail right of way in Mission Viejo.
