Township of New Britain, PA FLOODPLAIN OVERLAY DISTRICT REGULATIONS

Those areas identified as Zone A 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 sources shall be used when available. Where other acceptable information is not available, the base flood 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.

AO and AH Area. Those areas identified as Zones AO and AH on the FIRM and in the FIS. These areas are subject to inundation by one-percent-annual-chance shallow flooding where average depths are between one and three feet. In Zones AO and AH, drainage paths shall be established to guide floodwaters around and away from structures on slopes.

[Amended by Ord. 2017-06-07, 6/5/2017]

The above-referenced FIS and FIRMs, and any subsequent revisions and amendments, are hereby adopted by New Britain Township and declared to be a part of this chapter.

Boundary Variances.

Where there are any differences or variances between the boundaries of the various areas in the Floodplain Overlay District, the interpretation applying the strictest floodplain area to the greatest amount of land shall be followed. In all cases, the FIS-delineated boundary shall be met.

Where there are any differences or variances concerning the boundary of the Floodplain Overlay District, the interpretation applying the district to the greatest amount of land shall be followed. In all cases, the FIS-delineated boundary shall be met.

Hereafter, any changes in the area designated as floodplain shall be subject to the review and approval of FEMA.

Changes in Floodplain Overlay District Delineations.

The areas considered to be floodplain may be revised or modified by the Board of Supervisors 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 shall be made without prior approval from FEMA.

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 to the special flood hazard area by submitting technical or scientific data.

Disputes. Should a dispute arise concerning the identification of any floodplain area, an initial determination shall be made by the Township Engineer; and any party aggrieved by such decision may appeal to the Board of Supervisors. In such an appeal, the burden of proof shall be on the appellant.
