(A) Loss of the 100-year floodplain water storage capacity due to building or filling shall not be allowed. Any losses in capacity shall be off-set with an increase in capacity at other portions of the subdivision. No lot shall be platted where the primary structures are in the floodway fringe unless explicitly permitted by the Kokomo Zoning Ordinance. No building or filling is allowed in the Floodway.
(B) The Commission shall review all proposed subdivisions to determine whether the subdivision lies in a flood prone area as defined elsewhere by ordinance. If the Plan Commission finds the subdivision to be so located, the Plan Commission shall forward pertinent plans and material to the Indiana Department of Natural Resources for review and comment. The Plan Commission may require appropriate changes and modifications in order to assure that it is consistent with the need to minimize flood damage; adequate drainage is provided so as to reduce exposure to flood hazards; and that on-site waste disposal systems, if provided, will be located as to avoid impairment of them or contamination from them during the occurrence of the regulatory flood.
(C) All subdivision plats shall indicate the lowest or minimum floor elevation on every lot within 100 feet of the 100-year flood plain, detention basins or other designated flood areas, such that all structures will be protected from flooding during and beyond the 100-year storm event. Additionally, lots for which basements, walkouts and/or window-outs are not to be allowed shall be clearly indicated as such on subdivision plats.
(D) Any physical conditions regarding drainage, elevations, field tiles, flood area or related storm water features that are discovered in the field during construction that deviate from what was represented on the approved plans shall be brought to the attention of the City Engineer. Modifications to address the impacts of these changed conditions shall be prepared and submitted to the City Engineer for approval prior to work progressing. The developer may be required to perform additional work to address the situation. No changes to the approved design construction plans shall be permitted without the written approval of the City Engineer.
