Permeable Pavement Workshop

Porous pavement and permeable pavement surfaces temporarily store rainwater runoff before infiltrating into the subsoil. Replacing traditional pavement, this porous surface allows rainwater to infiltrate directly into the soil instead of running off into rivers and streams. Pollutants such as nitrogen, hydrocarbons from cars, pet waste, and other sources are filtered and removed by the soil's natural bioremediation, preventing the ground water from being polluted.

Over the last two decades, a wide range of permeable pavement materials have become readily available and widely used as alternatives to conventional pavement construction materials. Permeable pavements have proven to be practical, cost-effective, and watershed-friendly due to their ability to reduce stormwater runoff. Because these permeable materials allow water to pass through the surface (in the case of porous asphalt and concrete) or through void spaces (in the case of concrete pavers or grid pavers), both runoff volume and water quality impacts are reduced. This infiltration of runoff can reduce nuisance flooding, recharge groundwater supplies, filter out pollutants, and help keep drinking water healthy.

The Northcoast Stormwater Coalition and the California Coastal Commission sponsored a northern California workshop in the spring of 2007. Below are links to handouts, speaker brochures and slides from the presentations, available in PDF format.
