State Water Board Developing Statewide Urban Stormwater Infiltration Policy

The California State Water Resources Control Board (State Water Board) has begun its process to develop a new statewide Urban Stormwater Infiltration Policy. The goal of the proposed new policy is to establish statewide standards for stormwater infiltration to provide a consistent regulatory framework to "encourage infiltration of urban stormwater and increase local water supply resiliency, provide greater protection of stormwater quality, and develop projects with multiple benefits for communities."

The proposed policy scope includes the following components:

• Decision-making framework and support tools for assessing infiltration conditions, including potential prohibitions to protect groundwater quality.
