a district applicable to those areas of the Borough of Pottstown,
subject to inundation by the waters of the one-hundred-year flood
as delineated on the Flood Insurance Rate Map (FIRM) for Montgomery
County, Pennsylvania, as prepared by the Federal Emergency Management

In lieu of the above, the Borough of Pottstown 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,

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.
3.

1.
The degree of flood protection sought by the provisions of this chapter
is considered reasonable for regulatory purposes and is based on acceptable
engineering methods of study. Larger floods may occur or flood heights
may be increased by man-made or natural causes, such as ice jams and
bridge openings restricted by debris. This chapter does not imply
that areas outside the Floodplain Conservation District, or that land
uses permitted within such areas, will be free from flooding or flood
damages.
2.
This chapter shall not create liability on the part of the Borough
of Pottstown or any officer or employee thereof for any flood damages
that result from reliance on this chapter or any administrative decision
lawfully made thereunder.
