Lamont-Doherty Porous Asphalt Parking Lot
Description
The construction of the new Comer Geochemistry Building required the relocation of an existing 85 car parking lot. Stormwater management originally required the construction of a new detention basin and 500 feet of drainpipe excavated through rock and the existing main campus thoroughfare. A porous asphalt infiltration design alternative eliminated the drainpipe and detention basin, resulting in a zero net cost, 25% reduction in runoff, and 100% water quality treatment.
