The provisions of this article are intended
to prevent any use of a structure unduly obstructing the natural passage
of floodwater since such obstructions increase flood heights and flood
damage; and to prevent substantial damage to property or persons from
floodwaters.
In F Flood Districts, land may be used and buildings
or structures may be erected, altered or used for any of the following
uses and no other:
A. Tilling of the soil and the keeping and raising of
poultry and livestock, provided that not more than 100 fowl of any
kind or more than two head of farm livestock may be kept in a building
or enclosure, any part of which is closer to a property line than
100 feet.
B. Open-type public and private recreation areas and
parks, such as boat docks, natural swimming areas, hiking and bicycle
trails, golf courses and driving ranges.
C. Storage yards on lands adjacent to business and industrial
districts, provided that the equipment or material stored can easily
and quickly be moved in the event of flood possibilities.
D. Any other uses or structures customarily accessory
or incidental to the above uses, provided that any proposed structure
or uses shall be permitted only if:
(2) The applicant can prove that such structures or uses
will not obstruct the natural passage of floodwater or change the
channel course in such a way that flood hazards would consequently
increase either in upstream or downstream areas.
(3) Such structure is constructed and maintained in such
a way that likely floods (fifty-year expectancy) will not result in
substantial damage to property or person.
(4) All structures shall be constructed and placed on
the lot so as to offer the minimum obstruction to the flow of water
and shall be firmly anchored to prevent the structure from floating
downstream.
Permanent structures or any use other than those specified in §
253-174A through
D above, but not conforming with uses permitted in an adjoining district, may be permitted subject to authorization as a conditional use by the Planning Board, provided that the applicant submits the necessary topographic data, engineering and other studies to demonstrate that the area in question is not subject to flood conditions. These data and studies shall be prepared by a licensed professional engineer.
