[Amended 4-13-2009 by Ord. No. 1-2009; 7-13-1992 by Ord. No. 1-1992]
The identified floodplain area shall be any areas of Potter Township, subject to the one-hundred-year flood, which is identified as Zone A (Area of Special Flood Hazard) in the Flood Insurance Study (FIS) dated May 4, 2009, and the accompanying maps or the most recent revision thereof as issued by the Federal Emergency Management Agency, including all digital data developed as part of the Flood Insurance Study.
[Amended 7-13-1992 by Ord. No. 1-1992]
A. 
For the purposes of this chapter, the one-hundred-year flood elevation shall be used as the basis for regulation. When available, information from other federal, state and other qualified 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.
B. 
In lieu of the above, 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, etc., shall be submitted to sufficient detail to allow a thorough technical review by the Township.
The identified floodplain area may be revised or modified by the Township Board of Supervisors by resolution where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any 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 Township Planning Commission and any party aggrieved by this decision may appeal to the Board of Supervisors. The burden of proof shall be on the appellant.
