is being restored, before the damage occurred. (ALTERNATIVE LANGUAGE: Any repair, reconstruction or improvement of a structure taking place during a 10-year period, the cumulative cost of which, equals or exceeds fifty (50) percent of the market value of the structure either (i) before the "start of construction" of the first improvement of the structure, or (ii) if the structure has been "substantially damaged" and is being restored, before the damage occurred.) The term does not, however, include any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions. The term also does not include any alteration of a historic structure, provided the alteration will not preclude the structure’s designation as a historic structure. [NOTE: An alternative to exempting substantially improved/damaged historic structures from the elevation requirements of the ordinance by definition would be to handle them individually through the variance process. This option provides the community an opportunity to require that all reasonable measures are used to reduce the structure’s flood damage potential (e.g., by relocating utilities above the base flood elevation, using flood resistant materials where practicable, etc.), provided those measures do not preclude the structure’s designation as an “historic structure.” If this alternative is preferred, the last sentence of the previous paragraph (referring to “historic structures” should be deleted.] B. Any addition which increases the original floor area of a building by 25 percent or more. All additions constructed after the effective date of the first floodplain management regulations adopted by the community shall be added to any proposed addition in determining whether the total increase in original floor space would exceed 25 percent. 36. “Variance” means a grant of relief by a community from the terms of the floodplain management regulations. 37. “Violation” means the failure of a structure or other development to be fully compliant with the community’s floodplain management regulations. 160.02 STATUTORY AUTHORITY, FINDINGS OF FACT AND PURPOSE. 1. The Legislature of the State of Iowa has in Chapter 364, Code of Iowa, as amended, delegated the power to cities to exercise any power and perform any function it deems appropriate to protect and preserve the rights, privileges and property of the City or of its residents, and to preserve and improve the peace, safety, health, welfare, comfort and convenience of its residents. 2. Findings of Fact. A. The flood hazard areas of the City are subject to periodic inundation which can result in loss of life and property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures for flood protection and relief, and impairment of the tax base all of which adversely affect the public health, safety and general welfare of the community. B. These flood losses, hazards, and related adverse effects are caused by: (1) The occupancy of flood hazard areas by uses vulnerable to flood damages which create hazardous conditions as a result of being inadequately elevated or otherwise protected from flooding; and (2) The cumulative effect of obstructions on the floodplain causing increases in flood heights and velocities. cty_hr_d_160.doc -5- 4/15/2021
