Fremont enforces the Alameda Countywide Clean Water Program and C.3 post-construction requirements for new and redeveloped sites over 10,000 square feet.
Fremont is a co-permittee under the San Francisco Bay Regional Water Board's Municipal Regional Stormwater NPDES Permit. Under Provision C.3, new development and significant redevelopment creating or replacing 10,000 square feet or more of impervious surface must incorporate Low Impact Development (LID) treatment features like bioretention, green roofs, or permeable pavement. Single-family homes are generally exempt from C.3 but must manage runoff to avoid flooding neighbors. Discharging non-stormwater (soapy wash water, paint, motor oil) into storm drains is prohibited and carries fines up to 10,000 dollars per day. Construction sites must file a SWPPP and install BMPs (silt fence, stabilized entrance) before breaking ground.
