A. 
Description of districts.
(1) 
Basis of districts. The various floodplain districts shall include areas subject to inundation by waters of the 100-year flood. The basis for the delineation of these districts shall be the most recent Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) of July 5, 2000, or the most recent revision thereof.
[Amended 8-21-1990 by Ord. No. 676-C; 12-19-1995 by Ord. No. 700-C; 6-20-2000 by Ord. No. 732-C]
(a) 
The FW (floodway area) is delineated for purposes of this chapter using the criteria that a certain area within the floodplain must be capable of carrying the waters of the 100-year flood more than one foot at any point. The areas included in this area are defined in the Floodway Data Table contained in the Flood Insurance Study as prepared by the FEMA and shown on the accompanying FIRM.
(b) 
The FFA (flood-fringe area) shall be that area of the 100-year floodplain not included in the floodway. The basis for the outermost boundary of this area shall be the 100-year-flood elevations contained in the flood profiles provided in the FIS.
(2) 
Overlay concept.
(a) 
The floodplain districts described above shall be overlays to the existing underlying districts as shown on the Official Zoning Ordinance Map,[2] and as such, the provisions for the floodplain districts shall serve as a supplement to the underlying district provisions.
[2]
Editor's Note: The Zoning Map is on file in the Borough offices.
(b) 
Where there happens to be any conflict between the provisions or requirements of any of the floodplain districts and those of any underlying districts, the more restrictive provisions and/or those pertaining to the floodplain districts shall apply.
B. 
Zoning Map. The boundaries of the floodplain district are delineated on the map entitled "Flood Insurance Rate Map" (FIRM) which is part of the Flood Insurance Study (FIS) prepared by the Federal Insurance Administration, dated July 5, 2000, or the most recent revision thereof. The FIRM is declared to be a part of both this chapter and the Official Zoning Map of the Borough of Cheswick.
[Amended 12-19-1995 by Ord. No. 700-C; 2-20-1996 by Ord. No. 703-C; 6-20-2000 by Ord. No. 732-C]
C. 
District boundary changes. The delineation of any of the floodplain districts may be revised by the Borough Council where natural or other changes have occurred and/or more detailed studies, conducted or undertaken by the United States Army Corps of Engineers or other qualified agencies or individuals, document the basis for such change. However, prior to any such change, approval must be obtained from the Federal Insurance Administration (FIA).
D. 
Interpretation of district boundaries. Initial interpretations of the boundaries of the floodplain districts shall be made by the Zoning Officer. Should a dispute arise concerning the boundaries of any of the districts, the Zoning Hearing Board shall make the necessary determination in accordance with the provisions of Article VIII.

All uses, activities and developments occurring within any floodplain district shall be undertaken only in strict compliance with the provisions of this article, other applicable requirements of this chapter and other ordinances of the Borough. In addition, all such uses, activities and developments shall be undertaken only in compliance with federal or state law, including Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. § 1334.
(2) 
Under no circumstances shall any use, activity and/or development adversely affect the capacity of the channels or floodways of any watercourse, drainageway or any other drainage facility or system.
B. 
Permitted uses. In the floodplain districts, the development and/or use of land shall be permitted in accordance with the regulations of the underlying district, subject to the following:
(1) 
In the floodway district, no development shall be permitted except where any rise in flood heights caused by the proposed development will be fully offset by accompanying improvements which have been approved by all appropriate local, state and federal authorities as required above.
(2) 
No manufactured home, whether used for residential or commercial purposes, shall be permitted in the floodway district.
[Amended 12-19-1995 by Ord. No. 700-C]
(3)

(4) 
No new construction shall be allowed unless a permit is obtained from the Department of Environmental Protection, Bureau of Dams, Waterways and Wetlands. Within any special floodplain area, no new construction or development shall be permitted unless it is demonstrated that the cumulative effect of the proposed development when combined with all other existing and anticipated development will not increase the elevation of the 100-year flood more than one foot at any point. Within any special floodplain area or general floodplain area, no new construction or development shall be permitted within an area measured 50 feet landward from the top-of-bank of any watercourse, unless a permit is obtained from the Department of Environmental Protection, Bureau of Dams, Waterways and Wetlands.
