Therefore, the Decherd, Tennessee City Council, does ordain as follows:
(2) Findings of fact. (a) The Decherd City Council wishes to maintain eligibility in the National Flood Insurance Program and in order to do so must meet the requirements of 60.3(d) of the Federal Insurance Administration Regulations found at 44 CFR Ch. 1 (10-1-88 Edition) and subsequent amendments.
(b) Areas of Decherd are subject to periodic inundation which could 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.
(c) These flood losses are caused by the cumulative effect of obstructions in floodplains, causing increases in flood heights and velocities; and by uses in flood hazard areas which are vulnerable to floods; or construction with is inadequately elevated, floodproofed, or otherwise unprotected from flood damages.
(3) Statement of purpose. It is the purpose of this chapter to promote the public health, safety and general welfare, and to minimize public and private losses due to flood conditions in specific areas. This chapter is designed to:
(a) Restrict or prohibit uses which are vulnerable to water or erosion hazards, or which cause in damaging increases in erosion, flood heights, or velocities; (b) Require that uses vulnerable to floods, including community facilities, be protected against flood damage;
14-19
(c) Control the alteration of natural floodplains, stream channels, and natural protective barriers which accommodate flood waters;
(d) Control filling, grading, dredging and other development which may increase erosion of flood damage, and;
(e) Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards.
(4) Objectives. The objectives of this chapter are:
(a) To protect human life and health;
(b) To minimize expenditure of public funds for costly flood control projects;
(c) To minimize the need for rescue and relief efforts associated with flooding;
(d) To minimize prolonged business interruptions;
(e) To minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, street and bridges located in floodable areas;
(f) To help maintain a stable tax base by providing for the sound use and development of flood prone areas;
(g) To ensure that potential buyers are notified that property is in a floodable area; and,
(h) To establish eligibility for participation in the National Flood Insurance Program. (Ord. #187, Nov. 1993)

(b) When flood elevation, data is available, new construction or substantial improvements of buildings shall be elevated or flood-proofed to elevations established in accordance with § 14-604(2)(b).
(8) Standards for subdivision proposals. Subdivision proposals and other proposed new development, including manufactured home parks or subdivisions, shall be reviewed to determine whether such proposals will be reasonably safe from flooding. If a subdivision proposal or other proposed new development is in a flood-prone area, any such proposals shall be reviewed to ensure that:
(a) All subdivision proposals shall be consistent with the need to minimize flood damage.
(b) All subdivision proposals shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage.
(c) All subdivision proposals shall have adequate drainage provided to reduce exposure to flood hazards.

14-606. Variance procedures. The provisions of this section shall apply exclusively to areas of special flood hazard.
(1) Board of zoning appeals. (a) The Decherd Board of Zoning Appeals shall hear and decide appeals and requests for variances from the requirements of this chapter.
(b) Variances may be issued for the repair or rehabilitation of historic structures (see definition) upon a determination that the proposed repair or rehabilitation will not preclude the structure's continued designation as a historic structure and the variance is the minimum to preserve the historic character and design of the structure.
(c) In passing upon such applications, the board of zoning appeals shall consider all technical evaluations, all relevant factors, all standards specified in other sections of this chapter, and:
(i) The danger that materials may be swept onto other property to the injury of others;
14-36
(ii) The danger to life and property due to flooding or erosion;
(iii) The susceptibility of the proposed facility and its contents to flood damage;
(iv) The importance of the services provided by the proposed facility to the community;
(v) The necessity of the facility to a waterfront location, in the case of a functionally dependent facility;
(vi) The availability of alternative locations, not subject to flooding or erosion damage, for the proposed use;
(vii) The relationship of the proposed use to the comprehensive plan and floodplain management program for that area;
(viii) The safety of access to the property in times of flood for ordinary and emergency vehicles;
(ix) The expected heights, velocity, duration, rate of rise and sediment transport of the flood waters and the effects of wave action, if applicable, expected at the site, and;
(x) 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, and streets and bridges.
(d) Upon consideration of the factors listed above, and the purposes of this chapter, the board of zoning appeals may attach such conditions to the granting of variances as it deems necessary to effectuate the purposes of this chapter.
(e) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result.
(2) Conditions for variances. (a) Variances shall be issued upon a determination that the variance is the minimum relief necessary, considering the flood hazard; and in the instance of a historical building, a determination that the variance is the minimum relief necessary so as not to destroy the historic character and design of the building.
(b) Variances shall only be issued upon (i) a showing of good and sufficient cause; (ii) a determination that failure to grant the variance would result in exceptional hardship; and (iii) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisance, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances.
(c) Any applicant to whom a variance is granted shall be given written notice that the issuance of a variance to construct a structure
14-37
below the base flood level will result in increased premium rates for flood insurance, and that such construction below the base flood level increases risks to life and property.
(d) The city administrator/recorder shall maintain the records
of all appeal actions and report any variances to the Federal Emergency Management Agency upon request. (Ord. #187, Nov. 1993)

(c) For reasons fully set forth in the findings of the board, the aforesaid circumstances or conditions are such that the strict application of the provisions of this chapter would deprive the applicant of any reasonable use of his land. Mere loss in value shall not justify a variance. There must be a deprivation of beneficial use of land.
(d) The granting of any variance shall be in harmony with the general purposes and intent of this chapter and shall not be injurious to the neighborhood, detrimental to the public welfare, or in conflict with the comprehensive plan for development.
(e) In reviewing an application for a variance, the burden of showing that the variance should be granted shall be upon the persons applying therefor. (1972 Code, § 11-910, as amended by Ord. #187, Nov. 1993)
