The following minimum standards shall apply for all construction and development proposed within the Floodplain Overlay Zone, except for development within the Floodway Subdistrict:
A. Fill.
(1) Disposal of fill, including but not limited to rubble, construction debris, woody debris, and trash, shall not be permitted in the Floodplain Overlay Zone.
(2) If engineered fill is used for building purposes, it shall meet all of the FEMA development criteria, including but not limited to:
(a) Extend laterally at least 15 feet beyond the building line from all points;
(b) Consist of soil or small rock materials only; sanitary landfills shall not be permitted;
(c) Be compacted and stabilized to provide the necessary permeability and resistance to erosion, scouring, and settling;
(d) Be no steeper than one vertical to two horizontal, feet unless substantiated data, justifying steeper slopes are submitted to, and approved by the Floodplain Administrator; and
(e) Be used to the extent to which it does not adversely affect adjacent properties.
(3) Any proposed development, including fill, proposed within the Floodway Subdistrict shall comply with § 600-1818.
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 insure 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 No. 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 food 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 § 600-1825, Development which may endanger human life, shall be stored at or above the regulatory flood elevation or 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 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, etc.) 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 in 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 Part, to the extent that they are more restrictive and supplement the requirements of this Part:
(1) International Building Code (IBC) 2009 or the latest edition thereof: Secs. 801, 1202, 1403, 1603, 1605, 1612, 3402, and Appendix G.
(2) International Residential Building Code (IRC) 2009 or the latest edition thereof: Secs. R104, R105, R109, R323, Appendix AE101, Appendix E and Appendix J.
