The San Mateo Countywide Water Pollution Prevention Program (SMCWPPP), a program of C/CAG, supports the 20 Towns/Cities and County of San Mateo with regional stormwater regulatory requirements at three primary scales. C/CAG supports its member agencies at the local scale with implementation of  jurisdictional requirements, including public outreach, training and annual reporting; at the countywide scale with green stormwater infrastructure planning and water quality monitoring among other activities; and at the regional scale with representation on Regional Municipal Stomrwater Permit issues and developing water pollution prevention programs and projects coordinated among the other Bay Area municipalities that are co-permittees under the Municipal Regional Permit.

Below are recent planning efforts completed by C/CAG on behalf of the San Mateo Countywide Water Pollution Prevention Program.
