Matched Legal Cases: ['§ 13', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14', '§ 14']

(1) Statutory authorization. The Legislature of the State of Tennessee has in Tennessee Code Annotated, §§ 13-7-201 through 13-7-210 delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. Therefore, the Decherd, Tennessee City Council, does ordain as follows:
(iii) Certificate from a registered professional engineer or architect that the non-residential flood-proofed building will meet the flood-proofing criteria in § 14-604(2)(b), where base flood elevation data is available. (see (b) below)
(d) Record the actual elevation (in relation to mean sea level or highest adjacent grade, whichever is applicable) of the lowest floor (including basement) of all new or substantially improved buildings, in accordance with § 14-604(2)(b).
(e) Record the actual elevation (in relation to mean sea level or highest adjacent grade, whichever is applicable) to which the new or substantially improved buildings have been flood-proofed, in accordance with § 14-604(2)(b).
(f) When flood-proofing is utilized, the city administrator/recorder shall obtain certification from a registered professional engineer or architect, in accordance with § 14-604(2)(b).
(g) Where interpretation is needed as to the exact location of boundaries of the areas of special flood hazard (for example, where there appears to be a conflict between a mapped boundary and actual field conditions) the city administrator/recorder shall make the necessary interpretation. The person contesting the location of the boundary shall be given a reasonable opportunity to appeal the interpretation as provided in § 14-606.
administrator/recorder shall require the lowest floor of a building to be elevated or floodproofed to a level of at least one (1) foot above the highest adjacent grade (lowest floor and highest adjacent grade being defined in § 14-602 of this chapter). All applicable data including the highest adjacent grade elevation and the elevations of the lowest floor of floodproofing shall be recorded as set forth in § 14-604(2).
In all areas of special flood hazard where base flood elevation data have been provided, including A zones, A1-30 zones, AE zones, AO zones, AH zones and A99 zones, and has provided a regulatory floodway, as set forth in § 14-603(2), the following provisions are required:
(a) Residential construction. New construction or substantial improvement of any residential building (or manufactured home) shall have the lowest floor, including basement elevated no lower than one (1) foot above the base flood elevation. Should said foundation perimeter walls be used to elevate a structure, openings sufficient to facilitate the unimpeded movements of flood waters shall be provided in accordance with standards of § 14-605(2)(c).
(b) Non-residential construction. New construction or substantial improvement of any commercial, industrial, or non-residential building shall have the lowest floor, including basement, elevated no lower than one (1) foot above the level of the base flood elevation. Buildings located in all A-zones may be flood-proofed in lieu of being elevated provided that all areas of the building below the required elevation are watertight with walls substantially impermeable to the passage of water, and are built with structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy. A registered professional engineer or architect shall certify that the standards of this subsection are satisfied. Such certification shall be provided to the city administrator/recorder as set forth in § 14-604(2)(b).
(iii) The interior portion of such enclosed area shall not be partitioned or finished into separate rooms in such a way as to impede the movement of floodwaters and all such petitions shall comply with the provisions of § 14-605(2) of this chapter.
(C) In or outside of an existing or new manufactured home park or subdivision, or in an expansion of an existing manufactured home park or subdivision, on which a manufactured home has incurred "substantial damage" as the result of a flood, any manufactured home placed or substantially improved must meet the standards of § 14-605(2)(d)(2)(A) and (B) above.
(C) The recreational vehicle must meet all the requirements for new construction, including anchoring and elevation requirements of § 14-605(2)(d)(i) or (ii)(A) and (B) above.
In all areas of special flood hazard where base flood elevation data or floodway data have not been provided, the provisions of § 14-604(3)(h) shall be utilized for all requirements relative to the base flood elevation or floodways.
(3) Standards for areas of special flood hazard Zones A1-30 and AE with established base flood elevation but without floodways designated. Located within the areas of special flood hazard established in § 14-603(2), where streams exist with base flood data provided but where no floodways have been provided, (Zones A1-30 and AE) the following provisions apply:
(b) New construction or substantial improvements of buildings shall be elevated or flood-proofed to elevations established in accordance with § 14-605(2).
(4) Standards for areas of shallow flooding (AO and AH Zones). Located within the areas of special flood hazard established in § 14-603(2), are areas designated as shallow flooding areas. These areas have special flood hazards associated with base flood depths of one to three feet (1' - 3') where a clearly defined channel does not exist and where the path of flooding is unpredictable and indeterminate; therefore, the following provisions apply:
(5) Standards for areas protected by flood protection system (A-99 Zones). Located within the areas of special flood hazard established in § 14-603(2) are areas of the 100-year flood protected by a flood protection system which is under construction but where base flood elevations and flood hazard factors have not been determined. With these areas (A-99 Zones) the following provisions apply:
(a) All provisions of § 14-604 and § 14-605(1) and (8) shall apply.
(6) Standards for areas of special flood hazard with established base flood elevation and with floodways designated. Located within the areas of special flood hazard established in § 14-603(2), where streams exist with base flood data and floodways provided, the following provisions apply:
(b) If § 14-605(6)(a) above is satisfied, new construction or substantial improvements of buildings shall be elevated or flood-proofed to elevations established in accordance with § 14-605(2).
(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).
