[Ord. 175, 8/5/2014, § 8-401]
The Identified Floodplain Area shall be:
Any areas of the Township, classified as special flood hazard areas ("SFHAs") in the FIS and the accompanying FIRMs dated September 26, 2014, and issued by FEMA or the most recent revision thereof, including all digital data developed as part of the Flood Insurance Study; and
Any Community Identified Flood Hazard Areas.
The above referenced FIS and FIRMs, and any subsequent revisions and amendments are hereby adopted by the Township and declared to be a part of this chapter.
[Ord. 175, 8/5/2014, § 8-402]
The Identified Floodplain Area shall consist of the following specific areas:
The A Area/District shall be those areas identified as an A Zone on the FIRM included in the FIS prepared by FEMA and for which no base flood elevations have been provided. For these areas, elevation and floodway information from other Federal, State, or other acceptable source shall be used when available. Where other acceptable information is not available, the elevation shall be determined by using the elevation of a point on the boundary of the identified floodplain area which is nearest the construction site.
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 in sufficient detail to allow a thorough technical review by the Township.
Community Identified Flood Hazard Areas shall be those areas where the Township has identified local flood hazard or ponding areas, as delineated and adopted on a "Local Flood Hazard Map" using best available topographic data and locally derived information such as flood of record, historic high water marks, soils or approximate study methodologies.
[Ord. 175, 8/5/2014, § 8-403]
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 FEMA. Additionally, as soon as practicable, but not later than six months after the date such information becomes available, the Township shall notify FEMA of the changes by submitting technical or scientific data.
[Ord. 175, 8/5/2014, § 8-404]
Should a dispute concerning any identified floodplain boundary arise, an initial determination shall be made by the Floodplain Administrator and any party aggrieved by this decision or determination may appeal to the Zoning Hearing Board pursuant to the procedures set forth in the Zoning Ordinance [Chapter 27]. The burden of proof shall be on the appellant.
[Ord. 175, 8/5/2014, § 8-405]
Prior to development occurring in areas where annexation or other corporate boundary changes are proposed or have occurred, the Township shall review flood hazard data affecting the lands subject to boundary changes. The Township shall adopt and enforce floodplain regulations in areas subject to annexation or corporate boundary changes which meet or exceed those in 44 CFR § 60.3.
