(A) All subdivision and planned unit development proposals shall be consistent with the need to minimize flood damage by complying with the requirements of this chapter and the Village Flood Hazard Area Ordinance or the County Special Flood Hazard Area Ordinance.
(B) Plats or plans for new subdivisions and planned unit developments shall display the following flood data:
(1) Boundary of the special flood hazard area and the boundary of the floodway, if shown on available flood boundary, floodway map, and flood insurance rate maps;
(2) Easements or lands dedicated to the public for channel maintenance purposes; and
(3) The base flood elevation for each building site.
(C) Encroachments, including fill, new construction, substantial improvements, and other development shall be prohibited within special flood hazard areas, unless the technical evaluation of the developer’s engineer demonstrates that encroachments shall not result in any significant increase in flood levels during the occurrence of the 100-year return period flood event.
(D) When a subdivision or part thereof is located in a flood-prone area as designated by the Federal Emergency Management Agency for which no base flood elevation has been provided, the subdivider shall provide, at his own expense, such hydrologic design data and calculations and utility and drainage plans as may be required by the village to assure that the subdivision is consistent with the need to minimize or eliminate flood damage, in accordance with the Village Flood Hazard Area Development Ordinance or the County Special Flood Hazard Area Ordinance.
(E) If a letter of map revision or letter of map amendment is required, it shall be acquired prior to recording of the final plat.
