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.

1.
The degree of flood protection sought by the provisions of this Part
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 Part 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 Part shall not create liability on the part of the Borough of
Conshohocken or any officer or employee thereof for any flood damages
that result from reliance on this Part or any administrative decision
lawfully made thereunder.
