*NEW!!* Stormwater Control Plan & Checklist Process
In an effort to create a more streamlined process for review and approval of Stormwater Management Measures for development projects, the City of Fremont has created the Stormwater Control Plan (SCP) Process. See below for guidance on this new process:
- Stormwater Control Plan Survey - Take this survey to determine what submittal documents are needed for your development project.
- Stormwater Control Plan Guidance Manual - This guidance manual will go over the new process. See below for SCP materials. For additional SCP checklists, click here.
Who Regulates Stormwater Pollution?
The Municipal Regional National Pollutant Discharge Elimination System Stormwater Permit (also known as the MRP), issued by the San Francisco Regional Water Quality Control Board, mandates stormwater pollution prevention activities. The MRP requires 70+ municipalities in the Bay Area, including the City of Fremont, to place conditions on development projects to incorporate site design measures, source controls, treatment measures, and on larger projects, flow duration controls (FDCs). More information and development submittal requirements may be found in the tabs. Contact the Environmental Services Division with any questions you may have at (510) 494-4570.Preliminary & Final Stormwater Control Plan (SCP) Plan Set Components:
Stormwater Management Plan (SMP) - See below the sample SMP PDF and AutoCAD files to be used for project submittals.
