The following minimum standards shall apply for all construction and
development proposed to be undertaken within any identified floodplain area.
A. Fill. If fill is used, it shall:
(1) Extend laterally at least fifteen (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 (1) vertical to two (2) horizontal,
unless substantiated data justifying steeper slopes are submitted to and approved
by the borough.
(5) Be used to the extent to which it does not adversely
affect adjacent properties.
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. Sanitary sewer facilities and systems.
(1) All new or replacement on-site sewage systems and sanitary
sewer facilities and systems shall be located, designed and constructed to
minimize or eliminate flood damages and the infiltration of floodwaters. No
new on-site sewage system shall be placed in the floodway.
(2) Sanitary sewer facilities and systems shall be designed
to prevent the discharge of untreated sewage into floodwaters.
D. 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.
E. Streets. The finished elevation of proposed new streets
shall be no more than one (1) foot below the one-hundred-year base flood elevation.
F. Utilities. All utilities such as gas lines, electrical
and telephone systems being placed in an identified floodplain area should
be located, elevated (where possible) and constructed to minimize the chance
of impairment during a flood.
G. Storage. All materials that are buoyant, flammable, explosive or, in times of flooding, could be injurious to human, animal or plant life and are not listed in §
63-23, Restricted activities and development, shall be stored at or above the one-hundred-year base flood elevation and/or floodproofed to the maximum extent possible.
H. Placement of buildings and structures. All buildings
and structure 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.
I. 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 one-hundred-year base flood elevation
shall be securely anchored or affixed to prevent flotation.
J. Floors, walls and ceilings.
(1) Wood flooring used at or below the one-hundred-year base
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 this base flood elevation shall
be of a marine or water-resistant variety.
(3) Walls and ceilings at or below this base 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 this
base flood elevation shall be made of metal or other water-resistant material.
K. Paints and adhesives.
(1) Paints or other finishes used at or below the one-hundred-year
base flood elevation shall be of marine or water-resistant quality.
(2) Adhesives used at or below this base flood elevation
shall be of a marine or water-resistant variety.
(3) All wooden components (doors, trim, cabinets, etc.) shall
be finished with a marine or water-resistant paint or other finishing material.
L. 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 one-hundred-year base flood elevation.
(2) Electrical distribution panels shall be at least three
(3) feet above the base flood elevation.
(3) Separate electrical circuits shall serve lower levels
and shall be dropped from above.
M. Plumbing.
(1) Water heaters, furnaces and other mechanical equipment
or apparatus shall not be located below the one-hundred-year base elevation.
(2) No part of any on-site sewage disposal system shall be
located within any identified floodway 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 provisions shall be made for the drainage of
these systems in the event that floodwater infiltration occurs.
Where permitted within any identified floodplain area, all manufactured
homes and additions thereto shall be:
A. Placed on a permanent foundation.
B. Elevated so that the lowest floor of the manufactured
home is one and one-half (11/2) feet or more above the elevation of the one-hundred-year
flood.
C. Anchored to resist flotation, collapse or lateral movement.
