SANDAG and Caltrans, along with the San Dieguito River Park Joint Powers
Authority (SDRPJPA) as a partner agency, are pursuing a project to
restore land in the San Dieguito River Valley. The San Dieguito Lagoon
Restoration Project Phase II will convert former agricultural fields to saltwater
wetlands and enhance and maintain the natural flood control channel.
The restoration is estimated to cost $87 million and is
anticipated to begin in early January 2022.
project will expand and enhance the efforts of Southern California Edison
(SCE), which began restoring surrounding wetlands in 2011. Included in the
project is the planting of native species, maintenance of wetlands within the
Wetlands 19 and 6 sites, as well as the relocation of a single set of utility
poles into an existing San
Diego Gas & Electric utility corridor.
will help assist SCE with the maintenance of the lagoon inlet to ensure it
remains open to tidal flushing and provides sand to the beach.
LANE CLOSURE EXTENSION: Caltrans and SANDAG NCC crews will intermittently close one lane in each direction along El Camino Real in the City of San Diego, Monday to Friday, from 8 a.m. to 3:30 p.m. until Tuesday, April 19. The closures will allow crews to install water lines. Traffic will be maintained throughout construction.
Closures were previously scheduled through March 28 and have been extended to April 19 due to inclement weather. *Please note construction schedules are subject to change due to forecasted rain, fog, and cold temperatures.
This work is part of Phase II of the San Dieguito Lagoon Wetland Restoration Project. Please view the map below for additional information on closure locations.
San Dieguito Lagoon Wetland Restoration Project Phase II
Caltrans, SANDAG, and the San Dieguito River Park Joint Powers Authority are beginning Phase II of the San Dieguito Lagoon Wetland Restoration on Monday, January 3, 2022. Approximately 84 acres of wetlands will be restored after the completion of the restoration in 2024.
Construction activities will require the closure of the Dust Devil Nature Trail to all public access Mondays through Fridays. The trail will be open on Saturdays and Sundays from 6 a.m. to 6 p.m. January-March and October-December. From April-September, the trail will be open on Saturdays and Sundays from 6 a.m. to 7:30 p.m. The parking lot will be closed while the Dust Devil Nature Trail is closed.
Please note that crews will be removing non-native vegetation within the lagoon to prepare for the restoration. New native vegetation will be planted after completion. Construction crews will be hauling construction equipment and material on El Camino Real and Via De La Valle in the City of Del Mar. Please stay alert.
*Please note, construction schedules are subject to change due to inclement weather included forecasted rain, fog, or cold temperatures.

The establishment of a mix of coastal wetlands that
includes approximately 64 acres of tidal salt marsh, 15 acres of brackish
wetlands, and enhance an additional five acres of riparian habitat to benefit
local wildlife, supplementing restoration efforts completed within the San
Dieguito Lagoon in 2011.
The creation of a new trail paralleling El Camino Real
that will improve connectivity to the Dust Devil Nature Trail along the
southern edge of the project area and extend north near the El Camino Real
bridge for future connection to the Coast to Crest Trail.
The creation of a sustainable ecosystem that is prepared
for future sea level rise and anticipated flood conditions.
SDRPJPA, as lead agency has completed the Final
Environmental Impact Report (FEIR) for the San Dieguito Lagoon
Restoration Project Phase II as required by the California Environmental
Quality Act (CEQA). The responses to public comments received on the Draft EIR
are in Appendix R of the Final EIR.
SANDAG’s Environmental Mitigation Program (EMP) provides a portion of funds for this project that emphasizes the protection, preservation, and restoration of native habitats and local wildlife to offset the disturbance caused by the construction of regional and local transportation projects. The San
Dieguito Lagoon Restoration Project Phase II is being done in conjunction with
Caltrans to implement highway and railroad improvements as part of the
Interstate 5 North
Coast Corridor Program.
October 2009, SANDAG entered into an agreement with SDRPJPA, for the exclusive
rights to restore property owned by SDRPJPA (amended in 2016). At the same
time, the City of San Diego elected to use a portion of the SDRPJPA property to
mitigate the impacts associated with the El Camino Real Bridge Widening
plans of SANDAG, SDRPJPA, and the City of San Diego were combined in 2011 and
launched the development of a restoration plan, engineering and technical
studies, and environmental analysis for a larger restoration effort. In 2012,
Caltrans and the U.S. Army Corps of Engineers joined the three organizations in
creating coastal wetland restoration plans for the lagoon that will build upon
and expand previous restoration work.
engineering, hydrologic modeling, and technical studies
the restoration have been completed.
