12-713: IMPERVIOUS SURFACE STANDARDS NEAR WATER:
The maximum "impervious surface", as defined in section 12-809 of this title, within "shore land" areas, as defined in section 12-819 of this title, which are defined as those lands extending landward for two hundred feet (200') in all directions as measured on a horizontal plane from any shoreline, shall be thirty five percent (35%).
   A.   Exceptions:
      1.   Submerged lands shall be excluded from the lot size calculations above. Building location permits or building permit applications shall clearly show all existing and proposed impervious surfaces within the shoreline area and calculate the applicable percentage.
      2.   Developments may exceed these requirements by up to fifty percent (50%), provided all structures are not located closer than seventy five feet (75') from the shoreline. For example, the maximum percentage of impervious area may be increased from thirty five percent (35%) of the shore land area to fifty two and one-half percent (521/2%) of the shore land area, provided all structures are not closer than seventy five feet (75') from the shoreline.
