This project is designed to reduce the threat of altered hydrology and threat of loss of ecological integrity to the salt marsh vegetation community at Famosa Slough. In 2000, treatment ponds were built and vegetated at the south end of the Famosa Slough to clean all stormwater flows and retain dry-weather stormwater flows from the surrounding watershed of about 100 acres south of the Slough. The series of ponds and berms collect freshwater runoff as well as sediments, trash, and nutrients, but sediment has built up which reduces their effectiveness. The goal of this project is to restore the treatment ponds and berms and keep the dry weather freshwater and undesirable material from going into Famosa Slough, and thus reducing the risk of type conversion, and the resulting loss of ecological integrity of the strategic habitat of salt marsh vegetation community, and associated MSCP species. The treatment ponds are in urgent need of renovation to prevent the berms from failing and damaging the salt marsh habitat that is downstream. This project will remove sediment so that the dry weather freshwater is retained in the ponds rather than crossing the berm into the saltwater marsh areas, preserving the salt marsh.
