Impervious Surface shall mean those surfaces that prevent the entry of water into the soil. Common
Impervious Surfaces include, but are not limited to, rooftops, sidewalks, patio azeas, driveways,
pazking Lots, and other surfaces made of concrete, asphalt, brick, plastic, or any surfacing material
with a base or lining of an impervious material. Wood decking elevated two or more inches above
the ground shall not be considered impervious provided that the ground surface beneath the decking
is not impervious. Pervious areas beneath roof or balcony overhangs that are subject to inundation by
stormwater and which allow the percolation of that stormwater shall not be considered impervious
azeas. Swimming pools shall not be considered as Impervious Surfaces because of their ability to
retain additional rainwater, however, decking azound a pool may be considered impervious
depending upon materials used. Surfaces using pervious concrete or other similaz open grid paving
systems shall be calculated as fifty percent (50%) Impervious Surface, provided that no barrier to
natural percolation of water shall be installed beneath such material. Open grid Pavers must be
installed on a sand base, without liner, in order to be considered 50% impervious. Solid surface
pavers. (e.g., brick or brick appearing pavers as opposed to open grid pavers) do not qualify for any
reduction in impervious area, regazdless of type of base material used.
Unless otherwise and specifically provided for in these Land Development Regulations, or within
another Ordinance, or by other official action establishing specific Impervious Surface Limits for a
particulaz Lot or Development Project, the fifty percent (50%) Impervious Surface limit shall be the
maximum Impervious Surface limit for all new residential Development and redevelopment. In such
cases where a previously and lawfully developed residential Lot or Development Project exceeds the
fifty percent (50%) limit, redevelopment or additions to existing residential Development shall not
exceed the pre-construction Impervious Surface limit, provided the stormwater and drainage
requirements of Section 24-66 aze met.
