006 2004 Active Emeryville Crescent
Alameda County
  The Emeryville Crescent marsh is a 103.5-acre, fringing mixed pickleweed (Salicornia virginica) marsh shoreline between Powell Street in Emeryville and the eastern landfall of the Oakland Bay Bridge. Two sub-areas, Emeryville Crescent East (6a) and Emeryville Crescent West (6b), have been delineated due to the historical ownership and maintenance of the site. The site abuts an extremely heavily developed area on the east side of the Bay, with Interstate 80/580 directly adjacent to the east, and the approach to the San Francisco Bay Bridge adjacent to the south. Local anglers, dog-walkers, and other recreational groups frequently use the marshlands included in this site. Illegal activities such as dumping and littering, unauthorized camping, and public inebriation also occur along the edges of, and sometimes within, the marshlands of this site. The non-native Spartina infestations at Emeryville Crescent are in the early stages of establishment on the site. The individual locations of these plants are scattered across both of the Sub-Areas, but their overall acreage is small, at less than 2.6 acres or 2.5% of the combined marsh acreage. The infestation is located mainly along the bay edge of the marsh, adjacent to the open mudflats on the outer edge of the site, with a few scattered clones establishing on the interior portions of the marsh within Sub-Area 6b. The primary treatment method at this site is aquatic herbicide, which will be applied by conventional spray truck, backpack sprayer, and tracked amphibious vehicle. Partners on this site include the California Department of Parks and Recreation and the East Bay Regional Parks District.
