In addition to the other requirements of this
chapter, development in any identified floodplain area shall comply
with the following:
A. Within any FW (Floodway Zoning District), as established in Chapter
175, Zoning, the following provisions shall apply:
(1) Any new construction, development, use, activity or
encroachment that would cause any increase in flood heights shall
be prohibited.
(2) No new construction or development shall be allowed
unless a permit is obtained from the Department of Environmental Protection,
Bureau of Dams and Waterway Management.
B. Within any FA (General Floodplain Zoning District), as established in Chapter
175, Zoning, the following provisions shall apply:
(1) New construction and/or development shall be prohibited
within the area measured 50 feet landward from the top-of-bank of
any watercourse unless all required federal and state permits have

heights shall be permitted within a floodway area delineated by an
applicant.
C. Fill. Fill, where used, shall:
(1) Extend at least 15 feet laterally beyond all points
of the building.
(2) Be comprised only of soil or small rock materials
and shall not include organic waste.

and resistance to erosion, scouring or settling.
(4) Have a slope no greater than 50%.
(5) Not adversely affect adjacent properties.
D. Drainage. Storm drainage facilities shall be designed to convey the flow of stormwater runoff in a safe and efficient manner and in accordance with Chapter

H. Each lot within any identified floodplain area, as established in Chapter
175, Zoning, intended for residential structures shall be capable of providing a building site with a lowest floor elevation (including basement) at least 1 1/2 feet above the one-hundred-year flood elevation as defined in the FIS.
