[Ord. 782, 9/17/1986, § 301; as amended by Ord. 857, 9/20/1995, § 8]
1. 
The identified floodplain area shall be any areas of the Forest Hills Borough, subject to the one-hundred-year flood, which is identified as Zone A (Area of Special Flood Hazard) on the Flood Insurance Rate Map (FIRM) dated October 4, 1995, or the most recent revision thereof as issued by the Federal Emergency Management Agency (FEMA) which accompanies the Flood Insurance Study for Allegheny County, Pennsylvania. For the purposes of this Part, the one-hundred-year flood elevation shall be used as the basis for regulation. 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.
2. 
In lieu of the above, the Borough 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 Borough.
[Ord. 782, 9/17/1986, § 302]
The areas considered to be floodplain may be revised or modified by Council where studies or information provided by a qualified agency or person documents the need or possibility for such revision. No modification or revision of any floodplain area identified in the Flood Insurance Study prepared by the Federal Insurance Administration shall be made without prior approval from the Federal Insurance Administration.
[Ord. 782, 9/17/1986, § 303]
Should a dispute arise concerning the identification of any floodplain area, an initial determination shall be made by the Planning Commission and any party aggrieved by such decision may appeal to the Council. The burden of proof shall be on the applicant.
