Stormwater Runoff

  • What is stormwater runoff?

    Stormwater runoff is precipitation in an urban or suburban area that does not evaporate or soak into the ground but instead runs across the land and into the nearest waterway.

  • What can be done to ease the effects of development?

    There are many low-impact development techniques that can be installed around homes and buildings. Rain gardens, porous pavement and green roofs are a few techniques that will help reduce pollution from developed areas.

  • What are impervious surfaces?

    Impervious surfaces are paved or hardened surfaces that do not allow water to pass through. Roads, rooftops, sidewalks, pools, patios and parking lots are all impervious surfaces.
