WHEREAS, the City Council has determined that it would be in the best interest, health, safety and general welfare of the citizens of the City of Lubbock to make the changes indicated below; NOW THEREFORE: BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF LUBBOCK: / SECTION 1..-/THAT Section 21-16 of Chapter 21 of the Code, of Ordinances, of the City-of--Lubbock BE and is hereby amended to read as follows: Sec. 21-16. Definitions. Unless specifically defined below, words and phrases used in this article shall be interpreted to give them the meaning they have in common usage and to give this article its most reasonable application. Appeal means a request for a review of the city manager 1s inter- pretation of any provision of this article or a request for a variance. Area of shallow flooding means a designated AO, AH or VO Zone on a community 1s flood insurance rate map (FIRM) with a one per cent or greater annual chance of flooding to an average depth of one to three feet. This condition occurs where a clearly defined channel does not exist, where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow. Area of special flood hazard is the land in the flood plain within a community subject to a one per cent or greater chance of flooding in any given year. The area may be designated as Zone A on the flood hazard boundary map (FHBM). After detailed ratemaking has been completed in prepa- ration for publication of the FIRM, Zone A usually is refined into Zones A, II AE, AH, AO, Al-99, VO, Vl-3O, VE or V . .:~ i} Ir, 'i I t ll I l I ! 11 Base flood means the flood having a one per cent chance of being equaled or exceeded in any given year. Development means any man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations. Existing structures means, for the purpose of determining rates, structures for which the 11 start of construction11 commenced before the effec- tive date of the FIRM or before January 1, 1975, for FIRMs effective before that date. Flood or flooding means a general and temporary condition of partial or complete inundation of normally dry land areas from: (1) The overflow of inland waters. (2) The unusual and rapid accumulation of runoff of surface waters from any source. Flood hazard boundary map (FHBM) means an official map of a comunity where the areas within the boundaries of special flood hazards have been designated as Zone A. Flood insurance rate map (FIRM) means an official map of a community on which the Federal Emergency Management Agency has delineated both the areas of special flood hazards and the risk premium zones applicable to the comunity. Flood insurance study is the official report provided by the Federal Emergency Management Agency. The report contains flood profiles and the water surface elevation of the base flood, as well as the flood hazard i boundary map. I I I ! Flood plain or flood-prone area means any land area susceptible to being inundated by water from any source. Floodway (regulatory floodway) means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than one foot. Functionally dependent use means a use which cannot perform its in- tended purpose unless it is located or carried out in close proximity to -2- II 11 H ]\ H j:! 1:; t:' ,, iii 111 ~i; 1 water. The term includes only docking facilities, port facilities that are lii: necessary for the loading and unloading of cargo or passengers, and ship j building and ship repair facilities, but does not include long-term storage or related manufacturing facilities. Highest adjacent grade means the highest natural elevation of the !: ground surf ace prior to construction next to the proposed wa 11 s of a i structure. !i j,i :l L l Lowest floor means the lowest floor of the lowest enclosed area, in- cluding basement. An unfinished or flood resistant enclosure usable solely for parking of vehicles, building access or storage in an area other than a basement area is not considered a building's lowest floor, provided that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirement of Section 60.3 of the National Flood Insurance Program regulations. Manufactured home means a structure, transportable in one or more sec- tions, which is built on a permanent chassis and designed to be used with or without a permanent foundation when connected to the required utilities. For flood plain management purposes, the term "manufactured home" also in- cludes park trailers, travel trailers and other similar vehicles placed on a site for greater than 180 consecutive days. For insurance purposes, the term "manufactured home11 does not include park trailers., travel trailers and other similar vehicles. · Mean sea level means, for purposes of the National Flood Insurance j Program, the National Geodetic Vertical Datum (NGVD) of 1929 or other datum 1 , 1 ; to which base flood elevations shown on a community's flood insurance rate , map are referenced. i! I I i I Ii I i New construction means, for flood plain management purposes, struc- tures for which the start of construction commenced on or after the effec- tive date of a flood plain management regulation adopted by a community. Start of construction (for other than new construction or substantial improvements under the Coastal Barrier Resources Act) includes substantial improvement and means the date the building permit was issued, provided the actual start of construction, repair, reconstruction, placement or other im- provement was within 180 days of the permit date. The actual start means either the first placement of permanent construction of a structure on a site, such as the pouring of slab or footings, the installation of piles, the construction of columns or any work beyond the stage of excavation; or the placement of a manufactured home on a foundation. Permanent construc- tion does not include land preparation, such as clearing, grading and fill- ing; nor does it include the installation of streets and/or walkways; nor does it include excavation for a basement, footings, piers or foundations or the erection of temporary forms; nor does it include the installation on the -3- property of accessory buildings, such as garages or sheds, not occupied as dwelling units or not part of the main structure. Structure means a walled and roofed building that is principally above ! ground, as well as a manufactured home. Substantial improvement means any repair, reconstruction or im- provement of a structure, the cost of which equals or exceeds fifty (50) per cent of the market value of the structure either (1) before the improvement or repair is started, or (2) if the structure has been damaged and is being restored, before the damage occurred. For the purposes of this definition, substantial improvement is considered to occur when the first alteration of any wall, ceiling, floor or other structural part of the building commences, whether or not that alteration affects the external dimensions of the struc- ture. The term does not, however, include either (1) any project for im- provement of a structure to comply with existing state or local health, san- itary or safety code specifications which are solely necessary to assure safe living conditions, or (2) any alteration of a structure listed on the National Register or Historic Places or a state inventory of historic places. Variance is a grant of relief to a person from the requirements of this article when specific enforcement would result in unnecessary hardship. A variance, therefore, permits construction or development in a manner oth- erwise prohibited by this article. Violation means the failure of a structure or other development to be in full compliance with a community's flood plain management regulations. A structure or other development without the elevation certificate, other cer- tifications or other evidence of compliance required in Sections 60.3(b)(5), (c)(4), (c)(lO), (d)(3), (e)(2), (e)(4) or (e)(5) of the National Flood Insurance Programs regulations is presumed to be in violation until such time as that documentation is provided. Water surface elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929 (or other datum where specified), of floods of various magnitudes and frequencies in the flood plains of coastal or riverine areas. SECTION 2. THAT Section 21-19 of Chapter 21 of the Code of Ordinances of the City of Lubbock BE and is hereby amended to read as follows: Sec. 1-19. Administration. (a) The city manager is hereby appointed to administer and implement the p ovisions of this article and the National Flood Insurance Program reg- ulati ns which pertain to flood plain management; however, the issuing of -4- permits and the review of plans and maps may be delegated to the building 'i official and such other persons that the city manager may select.

In all areas of special flood hazards where base flood elevation data has been provided, as set forth in sections 21-24, 21-19(7) or 21-30(c) of this article, the following provisions are required: (1) Residential construction. New construction and substantial im- provement of any residential structure shall have the lowest floor, including basement, elevated to or above the base flood elevation. A registered professional engineer, architect or land surveyor shall submit a certification to the building offi- cial that the standard of this subsection, as proposed in sec- tion 21-27(1), is satisfied. (2) Nonresidential construction. New construction and substantial improvement of any commercial, industrial or other non- residential structure shall either have the lowest floor, in- cluding basement, elevated to or above the base flood level, or together with attendant utility and sanitary facilities, be de- signed so that below the base flood level the structure is watertight with walls substantially impermeable to the passage of water and with structural components having the capability of -8- l j resisting hydrostatic and hydrodynamic loads and effects of buoyancy.

(a) All manufactured homes to be placed within Zone A shall be installed using methods and practices which minimize flood damage. For the purpose of this requirement, manufactured homes must be elevated and anchored to resist flotation, collapse or lateral movement. Methods of anchoring may include, but are not limited to, use of over-the-top or frame ties to ground anchors. This requirement is in ad- dition to applicable state and local anchoring require- ments for resisting wind forces. (b) All manufactured homes shall be in compliance with section 21-31(1). (c) All manufactured homes to be placed or substantially im- proved within Zones Al-30, AH and AE on the city's FIRM shall be elevated on a permanent foundation such that the lowest floor of the manufactured home is at or above the -9- base flood elevation and shall be securely anchored to an adequately anchored foundation system in accordance with this section. SECTION 9. THAT Section 21-32 of Chapter 21 of the Code of Ordinances of the City of Lubbock BE and is hereby amended to read as follows: Sec. 21-32. Same-Floodways. Located within areas of special flood hazard established in section 21-24 are areas designated as floodways. The following provisions shall apply to such areas: (1) Encroachments are prohibited, including fill, new construction, substantial improvements and other developments unless certifi- cation by a registered professional engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels during occurrence of the base flood discharge.

SECTION 13. THAT Section 21-46 of Chapter 21 of the Code of Ordi- nances of the City of Lubbock BE and is hereby amended to read as follows: Sec. 21-46. Small lots. Variances may be issued for new construction and substantial im- provements to be erected on a lot of one-half acre or less in size con- tiguous to and surrounded by lots with existing structures constructed below the base flood level, provided the relevant factors in section 21-28 of this article have been fully considered. As the lot size increases beyond the one-half acre, the technical justification required for issuing the variance increases. -11- SECTION 14. THAT Section 21-49 of Chapter 21 of the Code of Ordi- nances of the City of Lubbock BE and is hereby amended to read as follows: Sec. 21-49. Prerequisites. (a) Variances shall be issued only upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. (b) Variances shall be issued only upon (1) a showing of good and sufficient cause; (2) a determination that failure to grant the variance would result in exceptional hardship to the applicant; and (3) a determination that the granting of a variance will not result in increased flood heights, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud on or victimization of the public or conflict with exist- ing local laws or ordinances. (c) Any applicant to whom a variance is granted shall be given writ- ten notice that the structure will be permitted to be built with the lowest floor elevation below the base flood elevation and that the cost of flood insurance will be commensurate with the increased risk resulting from the reduced lowest floor eleva- tion. SECTION 15. THAT Chapter 21 of the Code of Ordinances of the City of Lubbock BE and is hereby amended by adding a new section 21-50 to read as follows: Sec. 21-50.
