County-Wide Long-Term Routine Maintenance Permitting Program (IP 11-444)

The County-Wide Long-Term Routine Maintenance Permitting Program (IP 11-444) is a comprehensive initiative managed by OC Public Works to maintain existing flood control facilities and bridge structures throughout Orange County, California. The program focuses on preserving baseline as-built conditions to minimize flood-related hazards. Key activities include channel and basin maintenance such as silt and debris removal, slope repair, and vegetation control through trimming and herbicide application. Bridge-specific maintenance involves concrete repair, cleaning and painting of steel members, and the restoration of scour protection measures. Additionally, the program covers the removal of graffiti from channel walls, fences, and traffic signs using steam cleaners. Administrative oversight is provided by the Orange County Public Works Director, with Giles Matthews serving as the Regulatory Permitting Manager. The project adheres to the California Environmental Quality Act (CEQA), with a Notice of Determination confirming that incorporated mitigation measures prevent significant environmental impacts. Technical requirements include compliance with the State General Construction Permit's Best Management Practices and regulations from the Santa Ana and San Diego Regional Water Quality Control Boards. For specific restoration activities, a qualified biologist must develop a detailed restoration plan covering site selection, native seed mixes, and resource protection requirements for agency approval.
