Development Permits - Stormwater Requirements

Who Regulates Stormwater Pollution?


The Municipal Regional NPDES 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 Dublin, 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 may be found in the resources provided below or by calling the Public Works Department at (925) 833-6630.

Stormwater Design Submittal Forms


Stormwater Management Maintenance Agreement

A Stormwater Management Maintenance Agreement (O&M Agreement) is required for all projects incorporating stormwater treatment, hydromodification management measures, or trash capture devices. This agreement runs with the land and must be recorded with the Alameda County Recorder's Office. Template documents including instruction may be found below.

Biotreatment Soil Requirements

The biotreatment soil mix used in all bio-retention areas shall comply with the specifications required in the MRP.  If the biotreatment soil mix supplier is included on Alameda Clean Water Program’s “Biotreatment Soil Mix Supplier List," a Biotreatment Soil Mix Supplier Certification Statement shall be completed by the supplier and submitted to the City of Dublin a minimum of 14 days prior to delivery of the material to the job site.  If the biotreatment soil mix supplier is not included on the Supplier List, a Biotreatment Soil Mix Verification Checklist shall be completed by the supplier and submitted to the City of Dublin a minimum of 14 days prior to delivery of the material to the job site.
