Document Description
The project involves the repair of a section of an existing levee that failed during
severe 2022-2023 winter storms. The levee is located within the Contra Costa County Flood Control and Water Conservation District (District) jurisdiction. The failure was caused by the presence of pipes maintained by the IT Environmental Liquidating Trust (ITELT) and therefore they are responsible for the repair. The scope of work includes the removal of existing non-functional pipelines, scarification, and recompaction of the remaining levee subgrade, and backfilling the levee void with imported fill soils. The total depth to be backfilled is approximately 8 feet, and the work will cover an area of approximately 150 feet linear channel length by 70 feet levee width. The proposed repair work is focused on the restoration of the existing levee within its original footprint, with no encroachment into the Pacheco Creek channel. Best Management Practices (BMPs) such as silt fence and fiber rolls will be installed to prevent soil from entering into the adjacent creek. The California Department of Fish and Wildlife has been notified of this emergency repair. The repair will occur in dry weather and will take approximately seven days to complete.
The District issued an encroachment permit to ITELT for temporary access to District property for the repair and continued maintenance of the pipes
