Porous Asphalt Porous blacktop allows rainwater to penetrate the surface and recharge the ground water in a more natural fashion than a normal blacktop surface. At our Terminal 6 facility we now have 35 acres of porous asphalt and adjacent bioswales to absorb rainwater and runoff from the adjacent non-porous blacktop. Environmental considerations were a top priority. We were excited about the opportunity to incorporate more sustainable, porous blacktop into one of our facilities for the first time. While costs for porous blacktop are greater due to the need for a large layer of aggregate stone to absorb water under the asphalt, there are savings from reduced permitting requirements and the fact that no storm water system is necessary. Porous blacktop has the added benefit in warm weather of allowing storm water to cool before entering the river. In the end, we realized about $255,000 in savings by using porous blacktop, so this was a win for the environment and for our bottom line. Contact: Learn More:
