(A) The Council is authorized, but is not required to classify certain geographical areas as Impact Drainage Areas and to enact and promulgate regulations which are generally applied. In determining Impact Drainage Areas, the Council shall consider such factors as topography, soil type, capacity of existing regulated drains and distance from adequate drainage facility. The following areas shall be designated as Impact Drainage Areas, unless good reason for not including them is presented to the Board:
(1) A floodway or flood plain as designated by the Federal Emergency Management Agency.
(2) Land within 100 feet of each bank of any stream or main drainage channel.
(3) Land within 100 feet of the centerline of any stream or main drainage channel now in conduit.
(4) Land subject to flooding and/or areas that have previously exhibited drainage deficiencies.
(B) Land where there is not an adequate outlet, taking into consideration the capacity and depth of the outlet, may be designated as an Impact Drainage Area by resolution of the Council. Special requirements for development within any Impact Drainage Area shall be included in the resolution.
