(14) Standard Project Flood: A hypothetical flood, estimated by the Corps of En- gineers, representing the critical flood runoff volume and peak discharge that may be expected from the most severe combination of meterological and hydro- logic conditions that are considered reasonably characteristic of the geogra- phical region involved, excluding extremely rare combinations. (15) Storage Capacity of a Flood Plain: The volume of space above an area of .flood plain land that can be occupied by flood water of a given stage at a given time, regardless of whether the water is moving.

Includes but is not limited to objects such as buildings, factories, sheds, and cabins. a. Permanent Structure: A structure which is built of such materials and in such a way that it would commonly be expected to last and remain useful for a substantial period of time. b. Temporary _Structure: A structure which is built of such materials and in such a way-that it would commonly be expected to have a relatively short useful life, or is built for a purpose that would commonly be expected to be relatively short -term. 10.32 GENERAL PROVISIONS (a) Jurisdiction: The jurisdiction of this Section includes all lands, adjacent to each navigable reach of river or stream within the boundaries of Dane County, Wisconsin, that would be inundated by the regional flood. (b) District Boundaries: The boundaries of the general flood plain district shall be as they appear on the Zoning District Maps on file in the office of the Dane County Zoning Supervisor. (1) The Flood plain District boundary shall be subject to the provisions of 10.03 of the Zoning Ordinance. p.L / (2) Compliance with the provisions of this Section shall not be grounds for the removal of lands from the flood plain district unless such lands are filled to a height of at least two feet above the elevation of the standard project flood for the particular area and are contiguous to other lands lying outside the flood plain district. (c) Effect of Flood Plain District Regulations: The regulations set forth in this Section for the flood plain district shall apply only to the flood plains mapped on the of- ficial zoning map and shall be void and of no effect in areas not mapped as being included in the flood plain districts.
