Project Overview
Stabilization of the Del Mar bluffs is an ongoing, multiphase effort to maintain safe, stable, and reliable train tracks through this stretch of the LOSSAN Corridor. Our goals are to increase safety and service reliability and minimize the chances of track damage due to bluff retreat and seismic events. We accomplish this by installing supports and directing stormwater runoff. To ensure the long-term viability of the corridor, SANDAG is evaluating alternative strategies to relocate the tracks completely off the bluffs.
Schedule
Since 2003, SANDAG and the North County Transit District (NCTD) have completed five stabilization projects between Coast Boulevard and Torrey Pines State Beach. These projects included the installation of more than 380 support columns and investment in drainage infrastructure.
Phase 5
Phase 5 stabilization efforts included adding more support columns and drainage improvements, along with new retaining walls, erosion control measures, and native plants. These efforts, which occurred between 2024 and 2026, are critical for protecting the bluffs in the event of earthquakes, large storms, and sea level rise. SANDAG and NCTD completed this phase fall 2026.

Budget
Phase 5 cost roughly $88 million and was funded through a combination of state, federal, and local sources.
