SANDAG Rail Tracks Must Move Off Del Mar Bluffs: La Jolla Planners Demand Permanent Solution as $88M Stabilization Provides Only 30-Year Fix

The Crisis: Del Mar Bluffs Eroding 6 Inches Annually

The LOSSAN corridor runs along the coast from Pacific Beach through Bird Rock and La Jolla before reaching the vulnerable Del Mar bluffs section, making this a regional infrastructure priority. The La Jolla Community Planning Association (LJCPA) officially backed SANDAG's effort to relocate the LOSSAN rail corridor off the eroding Del Mar bluffs on September 18, 2026, rejecting the "no build" alternative. With bluffs receding approximately 6 inches annually in some areas, the tracks serving 4.5 million annual passengers face increasing risk from coastal erosion and sea level rise.

San Diego City Council President Joe LaCava, who serves as First Vice Chair of the SANDAG Board, attended the LJCPA meeting, signaling growing political momentum for permanent solutions. Recent September 2026 closures near San Clemente due to coastal erosion demonstrate the urgent infrastructure crisis facing California's coastal rail network.

For Pacific Beach contractors and residents, the LOSSAN corridor improvements directly impact daily commutes and regional connectivity. The rail line runs through Pacific Beach communities before reaching Del Mar, making this infrastructure investment critical for local transportation reliability.

Why SANDAG's $88M Phase 5 Stabilization Falls Short

SANDAG's Phase 5 stabilization project, which cost approximately $88 million, provides only 30 years of protection for the 1.7-mile stretch from Coast Boulevard to North Torrey Pines Road. Since 2003, SANDAG has installed more than 380 support columns across five stabilization phases—yet the bluffs continue eroding at rates that will accelerate with rising sea levels.

Chris Halter, a La Jolla resident and RideSD transit advocate who spearheaded the LJCPA resolution, emphasized that repeated temporary fixes become increasingly expensive and environmentally damaging. The LJCPA formally supported "any of the alignment alternatives currently under environmental review" for permanent track relocation.

The Multi-Billion Dollar Realignment Project

SANDAG is evaluating five alignment alternatives, including four tunnel options:

Northern San Dieguito Bridge to I-5 (with tunnel)
San Dieguito Bridge to I-5 (with tunnel)
Under Crest Canyon (with tunnel)
Under Camino Del Mar (with tunnel)
Del Mar Bluffs Double Track Reinforced (maintains existing alignment)

Tunnel alignments would extend more than 300 feet below surface in many areas. Total project costs range from $2 billion to $4 billion, with SANDAG securing $300 million in state budget funding for environmental clearance and design phases. Construction could begin in 2028 if environmental review proceeds on schedule, with rail operations continuing during construction.

Construction Timeline and Contractor Opportunities

The Environmental Impact Report timeline includes technical studies for noise measurement, archaeological surveys, and geotechnical investigations currently underway. A Draft EIR is expected for public review in 2026-2027, with final alignment selection targeted for 2026. Pacific Beach and Mission Beach contractors with coastal construction experience should monitor SANDAG's environmental review process, as tunnel boring and marine construction expertise from local firms will be essential for project success.

The rail corridor serves Pacific Beach, Mission Beach, Bird Rock, and La Jolla communities with commuter access to employment centers. Coastal contractors from these neighborhoods are ideally positioned for this multi-billion dollar infrastructure project, requiring expertise in:

Tunnel boring and underground construction
Coastal engineering and marine construction
Transportation infrastructure with active rail operations
Geotechnical engineering for coastal geology
California Coastal Commission permitting
Local subcontracting opportunities for Pacific Beach, La Jolla, and Bird Rock construction firms specializing in coastal work

Contractors should monitor SANDAG board meetings, engage with environmental review processes, and build relationships with transit agencies to position for this generational project. Pacific Beach and Mission Beach residents can attend SANDAG board meetings and provide public comment during the environmental review process to ensure local community input shapes final alignment decisions.

For Pacific Beach contractors specializing in coastal infrastructure and large-scale public works, the LOSSAN rail realignment represents a multi-year pipeline of opportunities requiring advanced technical capabilities and regional expertise. The rail line passes near Tourmaline Surfing Park in Pacific Beach and Bird Rock coastal area before reaching Del Mar.

Frequently Asked Questions

Why can't SANDAG just keep stabilizing the bluffs instead of moving the tracks?

SANDAG's $88M Phase 5 stabilization provides only 30 years of protection while bluffs continue eroding at 6 inches annually. Repeated interventions become increasingly expensive and environmentally damaging. Permanent relocation is more cost-effective long-term and eliminates ongoing erosion risk to critical transportation infrastructure serving 4.5 million annual passengers.

How much will full rail corridor realignment cost?

Full realignment cost estimates range from $2 billion to $4 billion depending on the alignment alternative selected. SANDAG has secured $300 million in state funding for environmental clearance and design phases. The project would be funded through a combination of federal, state, and local sources, potentially including regional sales tax revenue.

When will construction begin on the tunnel project?

Construction could begin in 2028 if environmental review proceeds on schedule. SANDAG is currently conducting technical studies and expects to release a Draft Environmental Impact Report in 2026-2027. Final alignment selection is targeted for 2026, with rail operations continuing during the multi-year construction phase.
