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
areas. Swimming pools shall not be considered as Impervious Surfaces because of their ability to
retain additional rainwater, however, decking around a pool may be considered impervious
depending upon materials used. Surfaces using pervious concrete or other similar 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 ~Trid Pavers must be
installed on a sand hale without liner in order to be considered 50`~/n impervious. Solid surface
