Porous Asphalt: IM West Parking Lot

Location: Okemos, MI 48864, USA

Description: Most surfaces that we walk on are impervious: they do not allow any water to pass through them. These paving materials lead to surface water runoff that picks up pollutants that flow into natural waterways. Porous asphalt allows for rain to infiltrate through the pavement surface into a recharge bed, where pollutants are captured and clean water will be retained and slowly filtered.
