The following minimum standards shall apply for all construction and development proposed within any identified floodplain area.
(A) Fill. Within any identified floodplain area the use of fill shall be prohibited.
(B) Drainage facilities. Storm drainage facilities shall be designed to convey the flow of stormwater runoff in a safe and efficient manner. The system shall ensure proper drainage along streets, and provide positive drainage away from buildings. The system shall also be designed to prevent the discharge of excess runoff onto adjacent properties.
(C) Water and sanitary sewer facilities and systems.
(1) All new or replacement water supply and sanitary sewer facilities and systems shall be located, designed and constructed to minimize or eliminate flood damages and the infiltration of floodwaters.
(2) Sanitary sewer facilities and systems shall be designed to prevent the discharge of untreated sewage into floodwaters.
(3) No part of any on-site sewage system shall be located within any identified floodplain 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 FEMA #348, Protecting Building Utilities From Flood Damages and The International Private Sewage Disposal Code shall be utilized.
(D) Other utilities. All other utilities such as gas lines, electrical and telephone systems shall be located, elevated (where possible) and constructed to minimize the chance of impairment during a flood.
(E) Streets. The finished elevation of all new streets shall be no more than one foot below the regulatory flood elevation.
(F) Storage. All materials that are buoyant, flammable, explosive, or in times of flooding, could be injurious to human, animal or plant life, and not listed in § 152.063, shall be stored at or above the regulatory flood elevation or flood proofed to the maximum extent possible.
(G) Placement of buildings and structures. All buildings and structures shall be designed, located and constructed so as to offer the minimum obstruction to the flow of water and shall be designed to have a minimum effect upon the flow and height of floodwater.
(H) Anchoring.
(1) All buildings and structures shall be firmly anchored in accordance with accepted engineering practices to prevent flotation, collapse or lateral movement.
(2) All air ducts, large pipes, storage tanks and other similar objects or components located below the regulatory flood elevation shall be securely anchored or affixed to prevent flotation.
(I) Floors, walls and ceilings.
(1) Wood flooring used at or below the regulatory flood elevation shall be installed to accommodate a lateral expansion of the flooring, perpendicular to the flooring grain without causing structural damage to the building.
(2) Plywood used at or below the regulatory flood elevation 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 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.
(J) Paints and adhesives.
(1) Paints and other finishes used at or below the regulatory flood elevation shall be of “marine” or “water-resistant” quality.
(2) Adhesives used at or below the regulatory flood elevation shall be of a “marine” or “water-resistant” variety.
(3) All wooden components (doors, trim, cabinets and the like) used at or below the regulatory flood elevation shall be finished with a “marine” or “water-resistant” paint or other finishing material.
(K) Electrical components.
(1) Electrical distribution panels shall be at least three feet above the base flood elevation.
(2) Separate electrical circuits shall serve lower levels and shall be dropped from above.
(L) Equipment. Water heaters, furnaces, air conditioning and ventilating units, and other electrical, mechanical or utility equipment or apparatus shall not be located below the regulatory flood elevation.
(M) Fuel supply systems. All gas and oil supply systems shall be designed to prevent the infiltration of floodwaters into the system and discharges from the system into floodwaters. Additional provisions shall be made for the drainage of these systems in the event that floodwater infiltration occurs.
(N) Uniform Construction Code coordination. The standards and specifications contained 34 Pa. Code Chapters 401 through 405, as amended and not limited to the following provisions shall apply to the above and other sections of this chapter, to the extent that they are more restrictive and supplement the requirements of this chapter:
(1) International Building Code (IBC) 2009 or the latest edition thereof: §§ 801, 1202, 1403, 1603, 1605, 1612, 3402 and Appendix G; and
(2) International Residential Building Code (IRC) 2009 or the latest edition thereof: §§ R104, R105, R109, R323, Appendix AE101, Appendix E and Appendix J.
