      (1)   Wood flooring shall be installed to accommodate a lateral expansion of the flooring, perpendicular to the flooring grain, without incurring structural damage to the building.
      (2)   Plywood shall be of a "marine" or water-resistant variety.
      (3)   Walls and ceilings at or below the regulatory flood elevation shall be designed and constructed of materials that are water-resistant and that will withstand inundation.
      (4)   Windows, doors and other components at or below the regulatory flood elevation shall be made of metal or other water-resistant material.
      (5)   The provisions of the UCC pertaining to this subsection and referenced in the 34 PA Code (Chapters 401-405 as amended) and contained in the 2003 IBC (Sees. 801.1.3, 1403.2, 1403.4, 1403.6 and 1404.2), the 2003 IRC (Sees. R323.1.7 & R501.3) and ASCE 24-98 (Chapter 6).
      (e)   Electrical Systems and Components.
         (1)   Electric water heaters, furnaces, air conditioning and ventilating systems, and other electrical equipment or apparatus, shall not be located below the regulatory flood elevation, and other electrical equipment or apparatus shall be permitted only at elevations above the regulatory flood elevation.
         (2)   Electrical distribution panels shall be at least three feet above the level of the 100-year flood elevation.
         (3)   Separate electrical circuits shall serve lower levels and shall be dropped from above.
         (4)   The provisions pertaining to the above provisions and referenced in the UCC and 34 PA Code (Chapters 401-405), as amended and contained in the 2003 IBC (Sec. 1612.4), the 2003 IRC (Sec. E323.1.5) and the 2000 IFGC (Sees. R301.5 and R1601.3.8) and ASCE 24 (Chapter 8) shall be utilized.
      (f)   Plumbing.
         (1)   Water heaters, furnaces and other mechanical equipment or apparatus shall not be located below the regulatory flood elevation.
         (2)   No part of any on-site sewage disposal system shall be located within any identified flood-prone area.
         (3)   Water supply systems and sanitary sewerage systems shall be designed to prevent the infiltration of flood waters into the system and discharges from the system into flood waters.
         (4)   All gas and oil supply systems shall be designed to prevent the infiltration of flood waters into the system and discharges from the system into flood waters. Additional provisions shall be made for the drainage of these systems in the event that flood water infiltration occurs.
   (g)    Paints and Adhesives. When used at or below regulatory flood elevation:
      (1)   Paint or other finishes shall be of a "marine" or water-resistant quality.
      (2)   Adhesives shall be of a "marine" or water-resistant quality.
      (3)   All wooden components (doors, trim, cabinets, etc.) shall be finished with a "marine" or "water-resistant" paint or other finishing material.
      (4)   The standards and specifications contained in 34 PA Code (Chapters 401-405, as amended) the 2003 IBC (Sees. 801.1.3, 1403.7 and Appendix G) and the 2003 IRC (Sees. R323.1.7).
   (h)   Storage. No materials that are buoyant, flammable, explosive, or, in time of flooding, could be injurious to human, animal or plant life, shall be stored below the regulatory flood elevation.
   (i)   Drainage Facilities. Storm drainage facilities shall be designed to convey the flow of surface waters without damage to persons or property. The system shall insure drainage at all points along streets and provide positive drainage away from buildings. The system shall also be designed to prevent the discharge of excess run-off onto adjacent properties.
(Ord. 79-6. Passed 8-20-79.)
   (j)   Sanitary Sewer Facilities.
      (1)   All new or replacement sanity sewer facilities shall be designed to minimize or eliminate flood damage and the infiltration of flood waters.
      (2)   Sanitary sewer facilities and systems shall be designed to prevent the discharge of untreated sewage into flood waters.
      (3)   No part of any on-site sewage system shall be located within any identified flood-prone area except in strict compliance with all State and local regulations for such systems. If any such system is permitted, it shall be located so as to avoid impairment to it, or contamination from it, during a flood.
      (4)   The design and construction provisions of the UCC and 34 PA Code (Chapters 401-405 as amended) and contained in the 2003 IBC (Appendix G. Sees. 401.3 and 401.4), the 2003 IRC (Sec. 323.1.6), the ASCE 24-98 (Sec. 8.3), FEMA #348, Protecting Building Utilities From Flood Damages and The International Private Sewage Disposal Code (Chapter 3) shall be utilized.

      (1)   Streets. The finished elevation of proposed new streets shall be not more than one foot below the regulatory flood elevation.
   (m)   Utilities. All utilities, such as gas lines and electrical and telephone systems, being placed in flood-prone areas, should be located, elevated (where possible) and constructed to minimize the chance of impairment during a flood.
