Water Quality

Do Your Part to Protect Water Quality

Did you know that a typical city block generates more than five times as much rainwater runoff as a forested area of the same size?  This is because rooftops and pavement don’t allow water to soak into the ground like forests, wetlands, and grasslands do. Instead, rainwater  runs off pavement into the nearest storm drain, where it’s transported to local streams, rivers and eventually the ocean. On its way to the storm drain, rainwater picks up pollutants like oil, antifreeze, pet waste, fertilizers, and pesticides. In most places, storm water does not get treated, so all of those pollutants end up in local waters.
