[Amended 12-8-2015 by Ord. No. 2015-6]
A. No encroachment, alteration, or improvement of any kind shall be
made to any watercourse until all adjacent municipalities which may
be affected by such action have been notified by the municipality
and until all required permits or approvals have first been obtained
from the Department of Environmental Protection Regional Office.
B. No encroachment, alteration, or improvement of any kind shall be
made to impede any watercourse unless it can be shown that the activity
will not reduce or impede the flood-carrying capacity of the watercourse
in any way.
C. In addition, FEMA and the Pennsylvania Department of Community and
Economic Development shall be notified prior to any alteration or
relocation of any watercourse.
D. Within any floodway area, no encroachments, including fill, new construction,
substantial improvements, or other development shall be permitted
unless it has been demonstrated through hydrologic and hydraulic analysis
performed in accordance with standard engineering practice that the
proposed encroachment would not result in any increase in flood levels
within the community during the occurrence of the base flood discharge.
The following minimum standards shall apply for all construction
and development proposed within any identified floodplain area:
A. Fill. If fill is used, it shall:
(1) Extend laterally at least 15 feet beyond the building line from all
points;

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, feet unless substantiated
data, justifying steeper slopes are submitted to and approved by the
Codes Enforcement Officer; and
(5) Be used to the extent to which it does not adversely affect adjacent
properties. The provisions contained in the 2003 IBC (Sections 1801.1
and 1803.4) shall be utilized.
B. Drainage facilities. Storm drainage facilities shall be designed
to convey the flow of stormwater runoff in a safe and efficient manner.

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.

and ASCE 24-98 (Section 5.6) shall be utilized.
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.

elevation shall be made of metal or other water-resistant material.
(5) The provisions of the UCC pertaining to this subsection and referenced
in the 34 Pa. Code (Chapters 401 to 405, as amended) and contained

6) shall be utilized.
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.
