Jurisdiction Notes

San José implements the Santa Clara Valley MRP (Municipal Regional Permit) issued by the San Francisco Bay Regional Water Board. The C.3 requirements are regionally consistent across Santa Clara County jurisdictions through the SCVURPPP program.

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 San José Department of Public Works / Planning, Building and Code Enforcement (PBCE) and the agency website before beginning construction.
