Bolsa Chica Lowlands Sea Level Rise Adaptation Project

The project is a re-envisioned restoration of the Bolsa Chica Lowlands wetland complex to improve the self-sustaining nature of the wetland complex in light of current sea level rise predictions, not available at the time of the original restoration. This will include reduction in water management gates and pump reliance, expansion of full tidal influence, … Continued

Randall Preserve Wetland Feasibility Study

Banning Ranch, now called the Randall Preserve, was permanently protected in December 2022 and title is held by the Mountains Recreation and Conservation Authority (MRCA). Coastal Corridor Alliance (CCA, formerly Banning Ranch Conservancy) has partnered with MRCA to complete a Wetland Feasibility Study for the Preserve’s tidal wetlands.

Restoration of Los Angeles River & Tributaries in Sepulveda Basin

The project will develop a 30% design plan set and supporting scientific and engineering studies to transform the Los Angeles River and tributary corridors within the Sepulveda Basin’s constrained streams, narrow riparian corridors (existing: ~60 acres) and disconnected uplands into roughly 8 miles and 600 acres (450 new acres) of restored meandering stream corridors, wide … Continued

Newland Marsh Restoration Permitting and Design

The Huntington Beach Wetlands Conservancy will prepare 60% and final restoration design plans, complete necessary studies for permitting, and secure permits for restoration at Newland Marsh, a 44.8-acre tidal wetland. The Project will create a culvert connection to the HB Channel to convey muted tides and sea water through the marsh, create a tidal channel … Continued

Ellwood Marine Terminal Restoration

Ellwood Marine Terminal is a 19 acre site that we hope will be restored to historic landforms after removal of tanks, pipes, buildings, and the soil is remediated and regraded. The area will restore the high point on Ellwood Mesa and reconnect the natural seep to the Dune Pond and vernal pools. Plant communities to … Continued

Buena Vista Lagoon Enhancement Project: 65% Design and Engineering Plans

The overall goals of the Buena Vista Lagoon Enhancement Project are to address sedimentation and invasive vegetation encroachment, as well as declining coastal biodiversity, degrading water quality, water circulation restriction, and increased vector concerns. The Buena Vista Lagoon is a 220-acre State Ecological Reserve that supports 8 state and federally listed threatened/ endangered wildlife and … Continued

Kalorama Wetland Restoration and Community Education Project

The Kalorama Wetland is located in Ventura, California at the mouth of a storm drain outlet, which was historically fed by its associated barranca and consisted of meandering streams along the beach. The site has relatively low native plant species richness and high non-native plant species richness. These non-native species are spreading and outcompeting the … Continued

San Joaquin Marsh Hydrology & Climate Adaptation Feasibility and Planning

The University of California, Irvine manages the UC Irvine San Joaquin Marsh Reserve, an approximately 200 acre wetland that is a remnant of a more extensive fresh to brackish water marsh ecosystem in coastal Orange County. Agricultural and urban development in Irvine during the 20th century drained shallow water aquifers, severed hydrological connections, concentrated water … Continued

Santa Margarita River Fish Passage and Bridge Replacement: Final Design

This fish passage project on the Santa Margarita River, located two miles north of Fallbrook in north San Diego County, addresses a principal threat to endangered Southern California steelhead. This project will provide final design plans to remove an aging flood-prone box culvert structure that is a fish passage barrier, and replace it with a … Continued
