(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 34 Pa. Code (Chapters 401 through 405, as amended) and contained in the current versions of the IBC (Appendix G and Sections 401.3 and 401.4) and IRC (Section 323.1.6), as per Pennsylvania State Law, and ASCE 24-98 (Section 8.3), FEMA No. 348, Protecting Building Utilities From Flood Damages, and the International Private Sewage Disposal Code (Chapter
3) shall be utilized.
D. Other Utilities. All other utilities, such as gas lines and electrical
and telephone systems, shall be located, elevated 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 which are not listed in §
8-406, Development Which May Endanger Human Life, shall be stored at or above the regulatory flood elevation and/or be floodproofed 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 floodwaters.
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.
(3) The design and construction requirements of the UCC pertaining to
this subsection as referred to in 34 Pa. Code (Chapters 401 through
405, as amended) and contained in the current version of the IBC (Sections
1605.2.2, 1605.3.1.2, 1612.4 and Appendix G501.3) and the IRC (Sections

(Section 5.6) shall be utilized.
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.
(5) The provisions of the UCC pertaining to this subsection and referenced in 34 Pa. Code (Chapters 401 through 405, as amended) and contained in the current version of the IBC (Sections 801.1.3, 1403.2, 1403.4, 1403.6 and 1404.2) and IRC (Sections R323.1.7 and R501.3), as per Pennsylvania State Law, and ASCE 24-98 (Chapter
6) shall be met.
J. Paints and Adhesives.
(1) Paints and other finishes used at or below the regulatory flood elevation
shall be of a marine or water-resistant quality.
(2) Adhesives used at or below the regulatory flood elevation shall be
of a marine or water-resistant variety.
