Managing Storm Water Runoff - Parking Lots

As more and more people own cars, more parking lots become necessary. Unfortunately, parking lots can adversely affect the environment as well as detract from community character. Paved parking lots are typically designed to collect and concentrate large areas of stormwater runoff, which can impact a receiving streams hydrography as well as water quality. Paved parking lots can generate heat, raising the surrounding areas air temperature and the temperature of the first flush of stormwater, creating significant ecological impacts. In Washington, the City of Olympia's Public Works Department found that parking lots account for 53% of imperviousness on a commercial site and 15% of multi-family sites. These figures are typical of most communities. Therefore, careful attention to their design will go a long way toward protecting your community's water resources.
