The case study highlights a pervious parking lot. The owner of Handy’s Hotels and Rentals paved an 18,000 square foot parking lot with porous asphalt. The parking lot services a thirty-unit residential apartment building and two triplex condominiums. Runoff from the rooftops of the apartment buildings and condominiums is conveyed beneath the pavement surface for infiltration.
The project is an alternative to the standard approach of capturing stormwater in a pipe, treating it, and discharging it to surface water. The porous asphalt helps to control runoff of pollutants and protects groundwater supplies.
