SCCWRP and its partners have developed updated best-practices guidance for how to site and maintain permeable pavement to sustain its effectiveness for infiltrating stormwater runoff.
The updated guidance, developed in July for the Ventura County Department of Public Works, explains how catchment conditions influence maintenance regimes, how to measure and track where maintenance is needed, and how to perform routine and restorative maintenance. This guidance is widely applicable across Southern California and beyond, although it does not consider snow- and freeze-thaw-related considerations.
The original “one-stop shop” guidance for permeable pavement was published in 2015 by the American Society of Civil Engineers (ASCE). The updated guidance is expected to help inform future updates to ASCE’s guidance.
Ventura County intends to use the guidance to manage existing permeable pavement, as well as plan for future installations, including supporting contracts for maintenance crews. It will be published in a forthcoming SCCWRP technical report.
