The Big Canyon Bluffs restoration project removed non- native, invasive species from the bluffs area immediately upslope from the Big Canyon Creek Restoration Project. Removal of the non-native species and replacement with natives appropriate to the coastal sage scrub community as well as other native, non-invasive species enhanced the flora in Big Canyon Creek, provided … Continued
The Santa Ana Watershed Association (SAWA), in partnership with the Orange County Conservation Corps, Riparian Repairs, and Featherly Regional Park plan to complete the removal of Arundo donax from the park. Arundo will be removed by a combination of chainsaw crews and a trackloader with attached cutting blade. Arundo that can’t be cut with the trackloader … Continued
The Newland Marsh is a component of the 180-acre Huntington Beach Wetlands, historically part of a large Santa Ana River mouth coastal wetland system extending several miles inland from the ocean. Channelization of the river and construction of Pacific Coast Highway isolated the site from tidal influence in the early 1900’s. The Newland Marsh is … Continued
This project restored 28 acres of wildlife habitat to native wetland, transitional and scrub plant communities along 1.7 miles of Upper Sulphur Creek, including removal of 3,600 feet of concrete channel to create a wider, soft-bottom stream channel. The goal of this project was to enable the City of Laguna Niguel to restore approximately 7,900 … Continued
This project developed a comprehensive program to remove non-native, invasive species from the San Juan Hydrologic Unit. The San Juan Hydrologic Unit (SJHU) is a generally trapezoidal-shaped area of 500 square miles in Orange, San Diego and Riverside Counties. This project included the SJHU area within Orange County, which is comprised of approximately half the … Continued
This project prepared final design and engineering plans for an ecological restoration project that will dredge 2.1 million cubic yards of sediment from Upper Newport Bay. The project addressed the impacts of habitat conversion resulting from sedimentation in the upper bay by dredging 2.1 million cubic yards of sediment and enhancing salt marsh and mudflat … Continued
This project enacted plans to deepen sediment basins in the upper bay up to -20 ft below mean sea level by dredging channels to promote tidal circulation and limit predator access to sensitive areas, expanding mudflat habitat in several locations to compensate for mudflats lost to dredging, and creating wetlands and California Least Tern nesting … Continued
This project enhanced approximately 50 acres of existing freshwater marsh habitat on the San Joaquin Freshwater Marsh Reserve. The project was part of an effort to restore the natural gradient found historically at Southern California coastal wetlands. The project was designed to restore some of the site’s most important natural characteristics which have been significantly … Continued
This project completed final engineering and design work for the restoration plan for Big Canyon Creek, a tributary to Upper Newport Bay. The project addressed wetland habitat, water quality, drainage and hydrologic issues, storm drain problems, tidal wetland exchange needs, sedimentation, long-term system sustainability, and public access. The restoration plan also addressed drainage problems and … Continued
This project helped the Huntington Beach Wetlands Conservancy acquire three key wetland parcels in Orange County. -Edison Acquisition: Acquired a 20-acre parcel of the Huntington Beach wetlands adjacent to the power plant. -Piccirelli Acquisition: Acquired 45 acres of the Huntington Beach wetlands located on either side of Magnolia Avenue. -Brookhurst Marsh Acquisition: Acquired the final … Continued
This project prepared a comprehensive restoration plan for the entire Huntington Beach Central Park. The Huntington Beach Wetlands consist of 118 acres of restored wetlands habitat along the southern coastline of Huntington Beach. The Huntington Beach Wetlands Conservancy owns and manages these wetlands and continues to work hand-in-hand with the California Department of Fish and … Continued
This project conducted a feasibility study for diverting up to six million gallons of flow per day from the East Garden Grove Winterburg Channel into treatment wetlands in Huntington Beach Central Park. The East Garden Grove-Wintersburg Channel (EGGWC) is an approximately 11.8 mile long regional floodcontrol facility in north/central Orange County. The EGGWC iscurrently the … Continued
