In 1999, the Port purchased and restored a 16-acre site adjacent to the existing Oro Lomo Marsh that had been diked and filled by the Oro Loma Sanitary District. Known as the Sonoma Baylands project, restoration of the 320-acre tidal wetland began in 1996 and was completed in September 2000, using clean dredge materials excavated from the Port of Oakland's 42-foot Harbor Deepening project. Monitoring and maintenance of the project will continue through 2005, whereupon the property likely will be transferred to a resource agency.
In the fall of 2004, the Port completed the enhancement and expansion of a nine-acre seasonal wetland along Damon Slough and adjacent to the existing Martin Luther King Jr. Regional Shoreline Park. Also, as part of this project, a ¼-mile connection has been constructed to fill in a gap in the San Francisco Bay Trail, a planned recreational corridor that, when complete, will encircle San Francisco and San Pablo Bays with a continuous 400-mile network of bicycling and hiking trails. To date, approximately 240 miles of the alignment—over half the Bay Trail's ultimate length—have been completed.
