Borough of Waynesboro, PA Design and Construction Standards

Extend laterally at least 15 feet beyond the building line from all points;

Consist of soil or small rock materials only; sanitary landfills shall not be permitted;

Be compacted to provide the necessary permeability and resistance to erosion, scouring, or settling;

(4)

Be no steeper than one vertical to two horizontal feet unless substantiated data justifying steeper slopes are submitted to and approved by the Borough; and

(5)

Be used to the extent to which it does not adversely affect adjacent properties.

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 and on-site water disposal sites. Plans shall be subject to the approval of the Borough Council. The Borough Council may require a primarily underground system to accommodate frequent floods and a secondary surface system to accommodate larger, less frequent floods. Drainage plans shall be consistent with local and regional drainage plans. The facilities shall be designed to prevent the discharge of excess runoff into adjacent properties.

Water and sanitary sewer facilities and systems.

All new or replacement water and sanitary sewer facilities and systems shall be located, designed and constructed to minimize or eliminate flood damages and the infiltration of floodwaters and shall be floodproofed up to the regulatory flood elevation.

Sanitary sewer facilities and systems shall be designed to prevent the discharge of untreated sewage into floodwaters.

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.

Other utilities. All other utilities such as gas lines, electrical, television cable and telephone systems shall be located, elevated (where possible) and constructed to minimize the chance of impairment during a flood and shall be floodproofed up to the regulatory flood elevation.

Streets. The finished elevation of all new streets shall be no more than one foot below the regulatory flood elevation.

Placement of buildings and structures. Whenever possible, all lots within a subdivision plan shall be designed such that adequate buildable area exists on each lot which is not within any identified floodplain area. If a part of any proposed structure in a land development plan extends into any identified floodplain area, such structure shall be reviewed for compliance with all applicable regulations of Chapter 295, Zoning, prior to approval of the plan.

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 elsewhere in the Borough of Waynesboro ordinances as dangerous to human life shall be stored at or above the regulatory flood elevation and/or floodproofed to the maximum extent possible.

Anchoring.

All buildings and structures shall be firmly anchored in accordance with accepted engineering practices to prevent flotation, collapse, or lateral movement.

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.

Floors, walls, and ceilings.

Wood flooring used at or below the regulatory flood elevation shall be installed to accommodate a lateral expansion of the flooring grain without causing structural damage to the building.

Plywood used at or below the regulatory flood elevation shall be of a "marine" or "water-resistant" variety.

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.

Paints and adhesives.

Paints or other finishes used at or below the regulatory flood elevation shall be of a "marine" or "water-resistant" quality.

Adhesives used at or below the regulatory flood elevation shall be of a "marine" or "water-resistant" quality.

All wooden components (doors, trim, cabinets, etc.) shall be finished with a "marine" or "water-resistant" paint or other finishing material.

Electrical components.

Electrical distribution panels shall be at least three feet above the one-hundred-year flood elevation.

Separate electrical circuits shall serve lower levels and shall be dropped from above.

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.

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 the floodwaters. Additional provisions shall be made for the drainage of these systems in the event that floodwater infiltration occurs.

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 and subsections of this chapter, to the extent that they are more restrictive and supplement the requirements of this chapter.

International Building Code (IBC) 2009 or the latest edition thereof: Sections 801, 1202, 1403, 1603, 1605, 1612, 3402, and Appendix G.

International Residential Building Code (IRC) 2009 or the latest edition thereof: Sections R104, R105, R109, R323, Appendix AE101, Appendix E and Appendix J.

Enclosed space below the lowest floor. Enclosed space below the lowest floor (including basement) may be permitted, provided that such space shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwater. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria:

At least two openings shall be provided having a total net open area of at least one square inch for every square foot of enclosed space subject to flooding.

The bottom of all openings shall be no higher than one foot above grade.
