   (B)  The structural requirements for the coastal sea of the state building code shall govern the general design and strength requirements of all piers and docks; however; the additional requirements  as set out herein shall take precedence.
   (C)  Piling having a diameter of less than six inches shall not be used on any pier or dock.  All piling shall penetrate the ground below hard bottom a distance of not less than six feet.  No concrete pile of less than eight inches in its smallest cross-sectional dimension shall be used. The wood pile shall be pressure treated with creosote to a retention of 18 pounds per square foot.
   (D)  The deck of all piers shall be constructed of planks having a thickness of not less than 5/4-inch of optional widths, and shall be supported by not less than l-l/2 feet on centers.  No stringer, joist, or rafter shall be used having a dimension of less than nominal two by six inches. Concrete, metal, or plastic materials may be used if in conformity with division (B) above.

   (F)  Floating docks, piers, and walkways shall meet the following additional requirements:
      (1)  All floating structures shall be no less than four feet in width. No horizontal dimension shall be greater than two times the other horizontal dimension.  Access piers shall be an exception; however, a suitable method of providing stability is used, such as finger projections or a minimum width of five feet for all access piers longer than eight feet is maintained.
      (2)  All floating piers shall have a freeboard (distance from water to top of deck) of not less than 16 inches.
      (3)  All fastenings shall be sufficient to withstand all movements anticipated in storm periods of hurricane force winds.  The Building Inspector shall have the right to disapprove any fastenings which do not appear to be sufficient.  All metal fastenings shall be galvanized or of metals resistant to corrosion.
      (4)  All floating piers shall be secured with pilings.  There shall be not less than one pile for each 80 square feet of pier surface.
      (5)  No houses or structures other than deck or gear boxes will be placed on floating piers.  All boxes shall be securely fastened to the pier.  No box shall be higher than four feet above the pier surface and occupy more than 2/5 of the surface.
