NPDES Resources for New Development Projects
County's Drainage Policy
The San Mateo Water Pollution Prevention Program (SMCWPPP) is a partnership of the City/County Association of Governments (C/CAG), each incorporated city and town in the county, and the County of San Mateo, which share a common National Pollutant Discharge Elimination System (NPDES) permit.
The SMCWPPP program makes a variety of resources available on its website http://www.flowstobay.org/ which are applicable to new development on a county-wide level. This website provides both specific resources applicable to the processing of development permits within the unincorporated areas of the County, as well as links to resources produced at the county-wide level, in order to inform contractors and home owners about NPDES requirements.
NPDES New Development Notifications
C.3 and C.6 Development Review Checklist
The C.3 and C.6 Development Review Checklist captures a formal calculation of existing, new and replaced impervious surface at the project site. The completed form is required for all projects requiring a Planning or Building permit that would result in any new area(s) of impervious surface. A completed form is required to be submitted at the time of permit application. If the project involves the development if more than one property at a time within properties owned by a common property owner one form shall be completed for all properties involved in development.
