(a) Uses in a flood plain district shall have the site plan approved by the Planning Commission. The Planning Commission may approve the site plan provided that the following requirements are met:
(1) The location of the proposed use shall not place any material, matter, or structure which may impede, retard, or change the direction of the flow of the waters, and the proposed use will not catch, collect, or add to the debris carried by such water to the damage or detriment of public or private property adjacent to the river, stream, or channel.
(2) All buildings to be erected in the flood plain district shall be elevated so that the first floor shall be above the highest expected flood water level.1 No basement or other floor shall be constructed below or at a lower elevation than the first floor.
(Ord. 82-1. Passed 2-16-82.)
1 The boundaries of the highest expected flood water level should be determined by empirical studies (past flood records) and engineering and planning studies of rainfall and the expected future runoff rates. The applicant shall be responsible for establishing such evidence in regard to the proposed use.
