Adams Barranca Debris Basin Sediment Cleanout (Specification No WP26-14 Project No. F60F3906)

The Adams Barranca Debris Basin Sediment Cleanout project, identified by Specification No WP26-14 and Project No F60F3906, involves the removal of approximately 80,000 cubic yards of accumulated sediment and debris from a 3.3-acre basin in unincorporated Ventura County. Managed by the Ventura County PWA Watershed Protection district, the project is essential for maintaining public safety and protecting downstream properties. Work is scheduled to take approximately 75 working days, with a projected start in May 2026. Access to the site will be via Adams Canyon Road and County-owned Right-of-Way, and all excavated materials must be disposed of at a site approved by the County of Ventura Integrated Waste Management Division. The project requires the use of heavy equipment, including wheel loaders, bulldozers, excavators, dump trucks, water trucks, and street sweepers. Due to the work occurring during nesting bird season, biological surveys must be conducted prior to and during operations to protect sensitive resources, and the removal of mature trees is strictly prohibited. Compliance measures include adhering to the May 2008 Final Program Environmental Impact Report and specific Best Management Practices, particularly BMPs 1, 3, 4, 10, 18, 21, 24, and 28. Additionally, surface water must be diverted around excavation areas to the bleeder pipe according to the Water Diversion Guide.
