Permeable Pavers
Description
Permeable pavers provide a transportation surface that lets water soak down through the gaps between individual pavers into a rock chamber below. The rock chamber is designed for bearing strength and water holding capacity. Water moves out of the voids in the rock chamber and percolates down through the soil, helping recharge ground water, filtering out pollutants, and cooling the water while releasing it slowly.
Benefits
Transportation related surfaces such as streets, parking lots and driveways account for 60% to 70% of impervious surfaces in urban areas. These impervious areas generate the majority of stormwater runoff. By using permeable pavers we can reduce the volume of runoff and the delivery of pollutants that transport dirty runoff from storm sewers directly to streams. This reduces flashy flows in receiving streams and improves water quality. Also, during periods of freeze and thaw in the winter, water will not pond to create icing on streets and parking lots, risking vehicle and individual safety.
