This project prepared final design and engineering plans and conducted environmental review for the Goat Canyon Enhancement Project. The Goat Canyon watershed crosses the U.S./Mexico border near the Goat Canyon Quarry site. Approximately 90% of this 4.6 square mile watershed occurs in Mexico where uncontrolled land uses have resulted in severe erosion and associated sedimentation … Continued
This project completed the feasibility and design studies for the second phase of salt marsh restoration at Border Field State Park in the south area of the Tijuana Estuary, involving approximately 480 acres.The Tijuana Estuary Tidal Restoration Program’s (TETRP) is a large multi-phased wetland restoration program involving up to 500 acres of restoration. Its primary … Continued
This project restored approximately 20 acres of intertidal salt marsh by excavating approximately 135,000 cubic yards of sediment. In order to re-create the variety of habitats usually present across the intertidal marsh plain, expand the area for wetland flora and fauna, and create a coastal habitat that can function similarly to a natural system, artificial … Continued
This project developed a watershed-wide invasive plant control plan in the Tijuana River Valley and implemented the first phase of exotics removal. The Tijuana River Valley is in one of the most important biological sites in California. It includes Prime riparian and salt march habitats within a county regional park, a state park, and a … Continued
This project restored approximately 300 acres of estuarine habitat in South San Diego Bay including the western salt ponds, the Chula Vista Wildlife Reserve, and Emory Cove. The project included excavation of degraded uplands to create intertidal and subtidal habitats, dredging former salt ponds to create tidal channels, breaching levees to restore tidal influence and … Continued
This project repaired a culvert at Famosa Slough to increase the tidal prism and yield an average of two additional horizontal feet in tidal inundation around the perimeter of the slough. The Famosa Slough is a 37-acre wetland located between Ocean Beach and the San Diego Sports Arena area. It is bisected by West Point … Continued
This project prepared a feasibility study and design plans to reactivate an inoperable culvert between Famosa Channel and Famosa Slough to increase the tidal prism in the slough. The Famosa Slough is a 37-acre wetland located between Ocean Beach and the San Diego Sports Arena area. It is bisected by West Point Loma Boulevard and … Continued
This project constructed a sediment basin, excavated and graded brow ditches, and installed native vegetation at the Los Penasquitos lagoon to manage sedimentation within the wetland system. The Los Peñasquitos Watershed is located within west–central San Diego County and includes portions of the City of San Diego, the City of Poway, the City of Del … Continued
This project prepared a hydrology and sedimentation study for the Los Peñasquitos Watershed and Lagoon system to characterize the sources and amounts of increased sediment loads and freshwater flows. The Los Peñasquitos Watershed is located within west–central San Diego County and includes portions of the City of San Diego, the City of Poway, the City … Continued
This project performed a preliminary assessment of sediment quality and depositional environment of the San Elijo Lagoon as the first step in a feasibility analysis of proposed dredging activities. It has been decades since San Elijo Lagoon was naturally connected to the Pacific Ocean. Human modifications to hydrology occurred at a rapid pace after the … Continued
This project prepared an integrated Watershed Restoration Action Strategy for overall management and restoration of the Escondido Creek watershed, the drainage for San Elijo Lagoon. The Escondido Creek Watershed covers approximately 54,112 acres in North County San Diego. While the watershed is rapidly being developed, large areas of vacant land and high quality habitat still … Continued
This project removed exotic plants from approximately 2.4 acres along the southern edge of San Elijo Lagoon and replanted the area with native riparian and buffer species. The project area is one of several targeted for removal of exotic species int he San Elijo Lagoon Conservancy Action Plan, which the Coastal Conservancy adopted in May … Continued
