When calculating impervious surface areas for buildings do not list the living/useable space square-footage, instead list the building roof square-footage measured to the outside edge of the eve or gutter. 1A non-vegetated surface area that either prevents or retards the entry of water into the soil mantle as under natural conditions before development; or that causes water to run off the surface in greater quantities or at an increased rate of fiow compared to the fiow present under natural conditions prior to development (e.g., roofs, driveways, etc.). Common impervious surfaces include, but are not limited to, roof, walkways, patios, driveways, parking lots, or storage areas, areas that are paved, graveled or made of packed or oiled earthen materials or other surfaces that similarly impede the natural inflltration of surface water or stormwater. For the purposes of applying the impervious surface thresholds, permeable pavement, vegetated roofs, and pervious surfaces with underdrains designed to collect stormwater runoff are considered impervious surface while an open uncovered fiow control or water quality facility is not.
