Permeable paving surfaces allow water to infiltrate into the ground instead of running off into streams, rivers, and lakes. Consequently, the amount of pollutants entering surface water sources is greatly reduced and aquifers are recharged. In addition, permeable paving reduces the heat island effect and helps prevent flooding.
In 2007, Arizona State University used pervious concrete to pave the parking lot in front of the ASU Art Museum in the Nelson Fine Arts Center.
