Jurisdiction Notes
Oakland implements the MRP (Municipal Regional Permit) through the Alameda County Clean Water Program. C.3 requirements are regionally consistent across Alameda County. The city's hilly terrain and proximity to the Bay make erosion control and water quality treatment especially important.
Remember: These local requirements are in addition to the SWRCB state construction permit. Both must be satisfied before breaking ground.
Disclaimer: This information is provided for general reference only. Always verify requirements directly with City of Oakland Bureau of Building / Public Works Department and the agency website before beginning construction.
