What is stormwater?
Stormwater is water from rain, snow, sleet or hail that flows across the ground and pavement. Typically, soil, vegetation, trees, and undisturbed areas can absorb a portion of stormwater. However, areas with impervious surfaces, such as concrete, asphalt, and brick, prevent water from infiltrating into the soil. This results in water flowing across these impervious surfaces. Roads, parking lots, sidewalks, etc. are all examples of surfaces that contribute to stormwater runoff.
