The following mitigation areas were established by the County to be used to mitigate impacts to sensitive biological resources resulting from County construction and maintenance projects. Use of credits is determined based on quality of habitat impacted in relation to quality of habitat available and is subject to approval by the U.S. Army Corps of Engineers, U.S. Fish & Wildlife Service, California Department of Fish & Game and Regional Quality Control Board.
SWEETWATER RIVER MITIGATION AREA The Sweetwater River Mitigation Area is located on land in the Sweetwater County Park owned and managed by the County Department of Parks and Recreation in the community of Bonita. The site includes approximately 60 acres of riparian habitat along the Sweetwater River, of which 26 was infested with arundo (Arundo donax).
Invasion by arundo poses a threat to the remaining native riparian communities. Arundo displaces native vegetation while offering little suitable habitat for native wildlife. Arundo also blocks the free-flow of water through river channels causing flooding conditions.
The goal of this restoration effort is to eradicate the invasive arundo from the 26 acres and restore the area with native riparian woodland vegetation by planting and natural recruitment. A secondary goal of the revegetation plan is to alleviate flooding in the area.
