SANDAG and the North County Transit District (NCTD) are
leading efforts to stabilize portions of the coastal bluffs in the
City of Del Mar. This integral part of the 351-mile Los Angeles – San Diego –
San Luis Obispo (LOSSAN) rail corridor is a vital link for passenger and
freight movements within San Diego County, as well as between San Diego, Los Angeles,
and points farther north.

Previous Bluff Stabilization Efforts
Since 2003, SANDAG and NCTD have completed three
stabilization projects along coastal bluffs between Coast Boulevard and Torrey
Pines State Beach. These stabilization projects saw the installation of more
than 200 support columns into the bluffs and critical investments into drainage infrastructure to help reinforce and protect the Del Mar bluffs.
Phase 4 efforts will install smaller support columns that
will stabilize localized areas and sea walls, construct a drainage channel on
top of the bluffs, repair concrete channels and storm drain outfalls, and
stabilize existing headwalls.
Phase 4 of the Del Mar Bluffs Stabilization project will cost approximately $5.8 million and is funded through a combination of state, federal, and local sources. Additional funding will be needed for ongoing stabilization over the next 20 years to preserve the track-bed support.
NCTD are currently seeking $100 million to accelerate the final two phases of
stabilization projects, Del Mar Bluffs Phases 5 and 6. Phase 5 is currently
funded through design and will address additional seismic and general
stabilization needs, install additional support columns, and replace more aging
drainage structures. Phase 6 will continue to provide long-term rehabilitation
and stabilization work, including protecting the base of the bluffs against
additional bluff retreat. Simultaneously, to ensure the long-term viability of
the corridor, SANDAG is seeking $5 million to evaluate alternative strategies
to move the tracks completely off the bluffs.
Importance of the LOSSAN Rail Line
The LOSSAN rail line is a vital component of the north-south
corridor through the San Diego region. The NCTD COASTER commuter rail service,
Amtrak’s Pacific Surfliner intercity service, and BNSF Railway freight service
all rely upon this segment of track to serve a combined 7.6 million passengers
a year and $1 billion in goods and services that are supported by rail line
reliability. In 2019, these services relied upon 44 passenger trains and 6
freight trains. By 2030 these numbers will have increased to 78 passenger
trains and 22 freight trains, only further illustrating the need for rail line
reliability. SANDAG is currently commissioning an in-depth analysis of the
economic impacts of LOSSAN rail corridor to the San Diego region.
