[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.
