The County board shall not permit changes to the floodplain that are inconsistent with the purpose and intent of this ordinance; or in conflict with the applicable rules and regulations of the Wisconsin Department of Natural Resources, (DNR) and the Federal Emergency Management Agency, (FEMA). In addition:

(a) Changes in the FPO Floodplain Overlay District boundaries shall not be permitted where the change will increase the flood stage elevation by 0.00 foot or more unless the petitioner has made appropriate legal arrangements with all affected units of government and all property owners affected by the stage increase, in accordance with 12.60.010 and 12.60.020 above. Petitions for FPO Floodplain Overlay District changes shall show the effects of the change within the associated flood fringe, and shall provide adjusted water surface profiles and adjusted floodplain limits to reflect the increased flood elevations. It shall be the policy of the County board of supervisors that any area removed from the FPO Floodplain Overlay District shall create an equivalent area and volume of floodplain in the vicinity of the removal.

(b) Removal of land from the floodplain shall not be permitted unless the land has been filled to an elevation at least two (2) feet above the elevation of the 100-year recurrence interval flood and provided that such land is contiguous to lands lying outside of the floodlands, in accordance with 12.60.030.

(c) No river or stream or watercourse shall be altered or relocated until a floodplain zoning change has been applied for and granted in accordance with the requirements of this section, and until the town in which the change is located and all adjacent communities have been requested to review and comment on the proposed alteration or relocation. The flood carrying capacity of within the altered or relocated portion of the watercourse shall be maintained.

(d) A copy of all notices for amending the floodplain provisions of this ordinance or the floodplain maps shall be transmitted to the Wisconsin Department of Natural Resources (DNR) and the Federal Emergency Management Agency (FEMA). No amendment to the floodplain boundaries or regulations shall be effective until approved by the DNR. The amendment procedure shall comply with the provisions of s. 59.69. [Code § 12.40-4.]
