Minimize unnecessary disruption of commerce, access and public service during times of flooding; 2. Require the use of appropriate construction practices in order to prevent or minimize future flood damage; 3. Manage filling, grading, dredging, mining, paving, excavation, drilling operations, storage of equipment or materials, and other development which may increase flood damage or erosion potential; 4. Manage the alteration of flood hazard areas, watercourses, and shorelines to minimize the impact of development on the natural and beneficial functions of the floodplain; 5. Minimize damage to public and private facilities and utilities; 6. Help maintain a stable tax base by providing for the sound use and development of flood hazard areas; 7. Minimize the need for future expenditure of public funds for flood control projects and response to and recovery from flood events; and 8.

In reviewing requests for variances, the Construction Code Enforcement/Licensing Board shall consider all technical evaluations, all relevant factors, all other applicable provisions of the Florida Building Code, this ordinance, an' the following: 1. The danger that materials and debris may be swept onto other lands resulting in furth injury or damage; 2. The danger to life and property due to flooding or erosion damage; 3. The susceptibility of ithe proposed development, including contents, to flood damage an the effect of such damage on current and future owners; 4. The importance of the services provided by the proposed development to the community; 5. The availability of alternate locations for the proposed development that are subject to lower risk of flooding or erosion; 6. The compatibility of the proposed development with existing and anticipate development; 9 i I OR BK 8732 PG 287 10 of 19 7. The relationship of the proposed development to the comprehensive plan and floodplain management program for the area; 8. The safety of access to the property in times of flooding for ordinary and emergency vehicles; 9. The expected heights, velocity, duration, rate of rise and debris and sediment transport of the floodwaters and the effects of wave action, if applicable, expected at the site; and 10. The costs of providing governmental services during and after flood conditions including maintenance and repair of public utilities and facilities such as sewer, gas, electrical and water systems, streets and bridges. 107.7 Conditions for issuance of variances. Variances shall be issued only upon: 1. Submission by the applicant, of a showing of good and sufficient cause that the unique characteristics of the size, configuration, or topography of the site limit compliance with any provision of this ordinance or the required elevation standards; 2. Determination by the Construction Code Enforcement/Licensing Board that: a. Failure to grant the variance would result in exceptional hardship due to the physical characteristics of the land that render the lot undevelopable; increased costs to satisfy the requirements or inconvenience do not constitute hardship; b. The granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, nor create nuisances, cause fraud on or victimization of the public or conflict with existing local laws and ordinances; and c. The variance is the minimum necessary, considering the flood hazard, to afford relief; 3. Receipt of a signed statement by the applicant that the variance, if granted, shall be recorded in the Office of the Clerk of the Court in such a manner that it appears in the chain of title of the affected parcel of land; and 4. If the request is for a variance to allow construction of the lowest floor of a new building, or substantial improvement of a building, below the required elevation, a copy in the record of a written notice from the Floodplain Administrator to the applicant for the variance, specifying the difference between the base flood elevation and the proposed elevation of the lowest floor, stating that the cost of federal flood insurance will be commensurate with the increased risk resulting from the reduced floor elevation (up to amounts as high as $25 for $100 of insurance coverage), and stating that construction below the base flood elevation increases risks to life and property.
