§ 165-22. Design and construction standards., Article I. Building Construction; Flood Damage Prevention, Chapter 165. Construction Codes, Part II. General Legislation, Code of Ordinances, Walnutport

Fill. If fill is used, it shall:

(1)

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

(2)

Consist of soil or small rock materials only. Sanitary landfills shall not be permitted.

(3)

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

(4)

Be no steeper than one vertical to two horizontal, unless substantiated data, justifying steeper slopes are submitted to, and approved by the Building Code Official.

(5)

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

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 runoff onto adjacent properties.

Sanitary sewer facilities. All new or replacement sanitary sewer facilities, and private package sewage treatment plants (including all pumping stations and collector systems) shall be designed to minimize or eliminate infiltration of floodwaters into the systems and discharges from the systems into the floodwaters. In addition, they should be located and constructed to minimize or eliminate flood damage and impairment.

Water facilities. All new or replacement water facilities shall be designed to minimize or eliminate infiltration of floodwaters into the system, and be located and constructed to minimize or eliminate flood damages.

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

Utilities. All utilities such as gas lines, 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.

Storage or production. No materials considered dangerous to human life shall be produced or stored in the regulatory flood elevation. The following list of materials and substances are considered dangerous to human life:

(1)

Acetone.

(2)

Ammonia.

(3)

Benzene.

(4)

Calcium carbide.

(5)

Carbon disulfide.

(6)

Celluloid.

(7)

Chlorine.

(8)

Hydrocloric acid.

(9)

Hydrocyanic acid.

(10)

Magnesium.

(11)

Nitric acid and oxides of nitrogen.

(12)

Petroleum products (gasoline, fuel oil, etc.).

(13)

Phosphorus.

(14)

Potassium.

(15)

Sodium.

(16)

Sulphur and sulphur products.

(17)

Pesticides (including insecticides, fungicides and rodenticides).

(18)

Radioactive substances.

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 flood water, and shall be prohibited within 50 feet on the top-of-bank landward of any watercourse.

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.

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.

Paints and adhesives.

(1)

Paints or 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 quality.

(3)

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

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.

(2)

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

(3)

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

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 sewage systems shall be designed to prevent the infiltration of floodwaters into the system and discharges from the system into floodwaters.

(4)

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