Saltmarsh habitat throughout Southern California is jeopardized by stormwater flows and sedimentation. In the Tijuana River Estuary, tidal channels and salt marsh habitat have been lost to sedimentation. The Goat Canyon Sediment Basins were constructed (2003-2005) to stop excess sediment flowing from a highly disturbed canyon in Mexico. These basins capture up to 60,000 cubic yards of material each winter and must be excavated every fall. These basins serve as a model for the region. The Stewardship Program plays an active role in managing this facility with tasks including: soliciting contractors and over-seeing basin work, promoting beneficial re-use of the material, promoting basin improvements such as trash capture and consolidating devices; monitoring basin conditions throughout the year and during excavation, and maintaining environmental permits necessary for facility operation.
