East Beach Sidewalk Permeable Pavement - Stormwater Discovery Tours

Where is this located? It is located between the lake and the Pavilion building.

What’s special about this place? You will never see water pooling on the surface of this kind of sidewalk. That’s because it is made of a hard but porous concrete material that allows water to soak through it into the ground. Once the water flows through the concrete it is infiltrated into the ground.

About Permeable Pavement

Permeable pavements include pervious concrete, porous asphalt, and spaced pavers, which are installed over special layers of sand, gravel, and soil. Pervious concrete and porous asphalt have small spaces that allow stormwater to soak through them, while interlocking pavers allow water to soak between the pavers. In addition to reducing runoff, permeable pavements help filter out pollutants. Because they are capturing and retaining pollutants, it is necessary to regularly clean the pavement or gaps between pavers to maintain their permeability.

Water quality benefit: Permeable pavement surfaces are effective in managing runoff from paved surfaces because they capture and absorb stormwater runoff at the source. When water soaks through permeable pavements, it prevents pooling of water on the surface. Permeable pavements are also effective at trapping pollutants as the runoff filters through the underlying layers of sand and gravel.
