[Amended 8-21-2017 by Ord. No. 179]
A. 
The Legislature of the Commonwealth. of Pennsylvania has, by the passage of the Pennsylvania Flood Plain Management Act of 1978, delegated the responsibility to local governmental units to adopt floodplain management regulations to promote public health, safety, and the general welfare of its citizenry. Therefore, the West Vincent Township Board of Supervisors does hereby order and establish the provisions set forth in this article.
B. 
In addition to the general goals listed in the statements of § 390-3, Purpose, and § 390-4, Community development objectives, it is the purpose of this district to:
(1) 
Promote the general health, welfare and safety of the community.
(2) 
Encourage the utilization of appropriate construction practices in order to prevent or minimize flood damage in the future.
(3) 
Minimize danger to public health by protecting water supply and natural drainage.
(4) 
Reduce financial burdens imposed on the community, its governmental units, and its residents, by preventing excessive development in areas subject to flooding.
(5) 
Comply with federal and state floodplain management requests.
These provisions shall apply to all lands within the jurisdiction of the Township of West Vincent and shown as being located within the boundaries of any identified floodplain conservation district, which are considered as a part of the Official Zoning Map.
A. 
The degree of flood protection sought by the provisions of this article is considered reasonable for regulatory purposes and is based on acceptable engineering methods of study. Larger floods may occur. Flood heights may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This article does not imply that areas outside any identified floodplain area, or that land uses permitted within such areas, will be free from flooding or flood damages.
B. 
This article shall not create liability on the part of the Township or any officer, employee or appointed professional thereof for any flood damages that result from reliance on this article or any administrative decisions lawfully made thereunder.
[Amended 8-21-2017 by Ord. No. 179]
[Amended 8-21-2017 by Ord. No. 179]
The identified floodplain area shall be those areas of the Township of West Vincent, Chester County, which are subject to the one-hundred-year flood, as identified in the Chester County Flood Insurance Study (FIS), dated September 29, 2017, and the accompanying maps as prepared by the Federal Emergency Management Agency (FEMA), or the most recent revision thereof, including all digital data developed as part of the Flood Insurance Study.
The identified floodplain area shall consist of the following specific areas:
A. 
FW (Floodway Area). The areas identified as "Floodway" in the AE Zone in the Flood Insurance Study prepared by the FEMA. The term shall also include floodway areas which have been identified in other available studies or sources of information for those floodplain areas where no floodway has been identified in the Flood Insurance Study.
B. 
FF (Flood-Fringe Area). The remaining portions of the one-hundred-year floodplain in those areas identified as an AE Zone in the Flood Insurance Study, where a floodway has been delineated. The basis for the outermost boundary of this area shall be the one-hundred-year flood elevations as shown in the flood profiles contained in the Flood Insurance Study.
C. 
FE (Special Floodplain Area). The areas identified as Zone AE in the Flood Insurance Study, where one-hundred-year flood elevations have been provided, but no floodway has been delineated.
D. 
FA (General Floodplain Area). The areas identified as Zone A in the FIS, for which no one-hundred-year flood elevations have been provided. When available, information from other federal, state, and other acceptable sources shall be used to determine the one-hundred-year elevation, as well as a floodway area, if possible. When no other information is available, the one-hundred-year elevation shall be determined by using a point on the boundary of the identified floodplain area which is nearest the construction site in question. In lieu of the above, and at the discretion of the Board of Supervisors, the Township may require the applicant to determine the elevation with hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, and any other information shall be submitted in sufficient detail to allow a thorough technical review by the Township Engineer.
The identified floodplain area may be revised or modified by the Board of Supervisors where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change, approval must be obtained from the Federal Insurance Administration (FIA).
Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Zoning Officer, and any party aggrieved by his or her decision may appeal to the Zoning Hearing Board. The burden of proof shall be on the appellant.
The Floodplain Conservation District shall be an overlay to the existing underlying districts, as shown on the Official Zoning Map of the Township. For the purpose of this article, the underlying base zoning district shall be designated RC Rural Conservation. If this article should be declared inappropriate to any tract by reason of amendment, special exception, variance or any other order of the Board of Supervisors, Zoning Hearing Board or court of competent jurisdiction, the base zoning provisions applicable to such tract shall be deemed the governing provisions and shall be enforced independent of this article.
A.
