A. All developments shall comply with the standards set out in the applicable zoning district governing the maximum density, maximum floor area, maximum impervious surface, minimum lot areas and width requirements and minimum open space requirements specified for each zoning district. In the case of residential uses, site capacity for any proposed development is equal to the net buildable area of the site multiplied by the density factor. The site capacity calculation provides the mechanism for subtracting from the base site area all portions of a site that are inappropriate for development.
