How do impervious surfaces affect how water will be distributed throughout the surrounding system? What are some ways to reduce their impact?
Impervious surfaces increase the amount of runoff and decrease the amount of groundwater because impervious surfaces, such as asphalt and concrete, cover the ground in human landscapes and diminish the amount of water that can seep into the ground. -reduce their impacts: more green spaces and parks in cities, instead of having the entire city covered in impervious materials -ex) GWU has a well-designed park - whatever part of the park that isn't grass is permeable bricks in which the water can seep through.
