Pervious Paving Systems are ecological, as they improve a site's water quality because they allow rainwater infiltration and natural groundwater recharge.
Low Impact Development is a new, comprehensive
land planning and engineering design approach with a goal of
maintaining and enhancing the pre-development hydrologic regime of
urban and developing watersheds.

Rain Gardens: Filtering and Recycling Rain Water
As our cities in Dickinson County grow, we continue to build houses, shopping centers and parking lots. This new development compacts the soil and creates impermeable surfaces. Storm water run off from parking lots and buildings runs into the sewer systems taking with it soil and chemical residues. This material ends up in the ground water system that we depend on. To help control run off and return rain water to the ground water system without all the impurities, we are now encouraging the installation of a rain garden.
