WHEREAS, the Legislature of the State of Texas has in Vernon's Texas Codes Annotated, Water Code 16.315, delegated the respons- ibility to local governmental units to adopt regulations designed to minimize flood losses; and WHEREAS, the floor hazard areas of the City of Euless are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief, all of which adversely affect the public health, safety and general welfare; and WHEREAS, these flood losses are created by the cumulative effect of obstructions in floodplains which cause an increase in flood heights and velocities, and by the occupancy of flood hazard areas by uses vulnerable to floods and hazardous to other lands because they are inadequately elevated, floodproofed, or otherwise protected from flood damage. NOW, THEREFORE, BE IT ORDAINED BY THE CITY COUNCIL OF THE CITY OF EULESS, TEXAS: DIVISION I SECTION A. STATEMENT OF PURPOSE It is the purpose of this ordinance to promote the public health, safety and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: (1) Protect human life and health; (2) Minimize expenditure of public money for costly flood control projects; (3) Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; (4) Minimize prolonged business interruptions; (5) Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains; (6) Help maintain a stable tax base by providing for the sound use and development of flood -prone areas in such a manner as to minimize future flood blight areas; and (7) Insure that potential buyers are notified that property is in a flood area. SECTION B. METHODS OF REDUCING FLOOD LOSSES In order to accomplish its purposes, this ordinance uses the following methods: (1) Restrict or prohibit uses that are dangerous to health, safety or property in times of flood, or cause excessive increases in flood heights or velocities; (2) Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; (3) Control the alternation of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters; (4) Control filling, grading, dredging and other development which may increase flood damage; (5) Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters or which may increase flood hazards to other lands. DIVISION II DEFINITIONS Unless specifically defined below, words or phrases used in this ordinance shall be interpreted to give them the meaning they have in common usage and to give this ordinance its most reasonable application. APPEAL - means a request for a review of the Flood Plain Administrator's interpretation of any provision of this ordinance or a request for a variance. APPEAL BOARD - means the Planning and Zoning Commission of the City of Euless, Texas. AREA OF SHALLOW FLOODING - means a designated A0, AH, or VO zone on a community's Flood Insurance Rate Map (FIRM) with a one percent chance or greater annual chance of flooding to an average depth of one to three feet 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. - 2 - ORDINANCE NO. 927, PAGE 2 OF 18 AREA OF SPECIAL FLOOD HAZARD - is the land in the floodplain within a community subject to a one percent 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 preparation for publication of the FIRM, Zone A usually is refined into Zones A, AE, AH, AO, Al -99, V0, V1 -30, VE or V. BASE FLOOD - means the flood having a one percent chance of being equalled or exceeded in any given year. CRITICAL FEATURE - means an integral and readily identifiable part of a flood protection system, without which the flood protection provided by the entire system would be compromised. DEVELOPMENT - means any man -made change in improved and unimproved real estate, including but not limited to buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations. ELEVATED BUILDING - means a nonbasement building (i) built, in the case of a building in Zones Al -30, AE, A, A99, A0, AH, B, C, X, and D, to have the top of the elevated floor, or in the case of a building in Zones V1 -30, VE, or V, to have the bottom of the lowest horizontal structure member of the elevated floor elevated above the ground level by means of pilings, columns (posts and piers), or shear walls parallel to the floor of the water and (ii) adequately anchored so as not to impair the structural integrity of the building during a flood of up to the magnitude of the base flood. In the case of Zones Al -30, AE, A, A99, A0, AH, B, C, X, D, "elevated building" also includes a building elevated by means of fill or solid foundation perimeter walls with openings sufficient to facilitate the unimpeded movement of flood waters. In the case of Zones V1 -30, VE, or V, "elevated building" also includes a building otherwise meeting the definition of "elevated building ", even though the lower area is enclosed by means of breakaway walls if the breakaway walls meet the standards of Section 60.3(e)(5) of the National Flood Insurance Program regulations. EXISTING CONSTRUCTION - means for the purposes of determining rates, structures for which the "start of construction" commenced before the effective date of the FIRM or before January 1, 1975, for FIRMS effective before that date. "existing construction" may also be referred to as "existing structures." 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 or tidal waters. (2) the unusual and rapid accumulation or runoff of surface waters from any source. - 3 - ORDINANCE NO. 927, PAGE 3 OF 18 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 community. FLOOD INSURANCE STUDY - is the official report provided by the Federal Emergency Management Agency. The report contains flood profiles, water surface elevation of the base flood, as well as the Flood Boundary - Floodway Map. FLOODPLAIN OR FLOOD -PRONE AREA - means any land area susceptible to being inundated by water from any source (see definition of flooding). FLOOD PROTECTION SYSTEM - means those physical structural works for which funds have been authorized, appropriated, and expended and which have been constructed specifically to modify flooding in order to reduce the extent of the areas within a community subject to a "special flood hazard" and the extent of the depths of associated flooding. Such a system typically includes hurricane tidal barriers, dams, reservoirs, levees or dikes. These specialized flood modifying works are those constructed in conformance with sound engineering standards. 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 a designated height. FUNCTIONALLY DEPENDENT USE - means a use which cannot perform its intended purpose unless it is located or carried out in close proximity to water. The term includes only docking facilities, port facilities that are necessary for the loading and unloading of cargo or passengers, and ship 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 surface prior to construction next to the proposed walls of a structure. LEVEE - means a man -made structure, usually an earthen embankment, designed and constructed in accordance with sound engineering practices to contain, control, or divert the flow of water so as to provide protection from temporary flooding.

An unfinished or flood resistant enclosure, usable solely for parking or 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 sections, which is built on a permanent chassis and is designed for use with or without a permanent foundation when connected to the required utilities. For flood plain management purposes the term "manufactured home" also includes park trailers, travel trailers, and other similar vehicles placed on a site for greater than 180 consecutive days. For insurance purposes the term "manufactured home" does not include park trailers, travel trailers, and other similar vehicles. MEAN SEA LEVEL - means, for purposes of the National Flood Insurance Program, the National Geodetic Vertical Datum (NGVD) of 1929 or other datum, to which base flood elevations shown on a community's Flood Insurance Rate Map are referenced. NEW CONSTRUCTION - means, for flood plain management purposes, structures for which the "start of construction" commenced on or after the effective 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 (Pub. L. 97 -348), includes substantial improvement and means that date the building permit was issued, provided the actual start of construction, repair, reconstruction, placement, or other improvement 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 construction does not include land preparation, such as clearing, grading and filling; nor does it include the installation of streets and /or walkways; nor does it include excavation for basement, footings, piers or foundations or the erection of temporary forms; nor does it include the installation on the 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, including a gas or liquid storage tank, that is principally above ground, as well as a manufactured home. - 5 ORDINANCE N0. 927, PAGE 5 OF 18 SUBSTANTIAL D PROVENENT - means any repair, reconstruction, or improvement of a structure, the cost of which equals or exceeds 50% 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 purpose 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 structure. The term does not, however, include either (1) any project for improvement of a structure to comply with existing state or local health, sanitary, 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 of Historic Places or a State Inventory of Historic Places. VARIANCE - is a grant of relief to a person from the requirements of this ordinance when specific enforcement would result in unnecessary hardship. A variance, therefore, permits construction or development in a manner otherwise prohibited by this ordinance. (For full requirements see Section 60.6 of the National Flood Insurance Program regulations.) VIOLATION - means the failure of a structure or other development to be fully compliant with the community's flood plain management regulations. A structure or other development without the elevation certificate, other certifications, or other evidence of compliance required in Section 60.3(b)(5), (c)(4), (c)(10), (d)(3), (e)(4), or (e)(5) 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. DIVISION III GENERAL PROVISIONS SECTION A. LANDS TO WHICH THIS ORDINANCE APPLIES The ordinance shall apply to all areas of special flood hazard with the jurisdiction of the City of Euless. SECTION B. BASIS FOR ESTABLISHING THE AREAS OF SPECIAL FLOOD HAZARD The areas of special flood hazard identified by the Federal Emergency Management Agency in a scientific and engineering report entitled, "The Flood Insurance Study for the City of Euless," dated October 3, 1984, with accompanying Flood Insurance Rage Maps and Flood Boundery - Floodway Maps (FIRM and FBFM) and any revisions thereto are hereby adopted by reference and declared to be a part of this ordinance. OROTNANCE NO. 927. PAGE 6 OF IfT 6 - SECTION C. ESTABLISHMENT OF DEVELOPMENT PERMIT A Development Permit shall be required to ensure conformance with the provisions of this ordinance. SECTION D. COMPLIANCE No structure or land shall hereafter be located, altered, or have its use changed without full compliance with the terms of this ordinance and other applicable regulations. SECTION E. ABROGATION & GREATER This ordinance is not intended to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this ordinance and another conflict or overlap, whichever imposes the more stringent restrictions shall prevail. SECTION F. In the interpretation and application of this ordinance, all provisions shall be; (1) considered as minimum requirements; (2) liberally construed in favor of the governing body; and (3) deemed neither to limit nor repeal any other powers granted under State statutes. SECTION G. wARNING & DISCLAIMER OR LIABILITY The degree of flood protection required by this ordinance is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. On rare occasions greater floods can and will occur and flood heights may be increased by man -made or natural causes. This ordinance does not imply that land outside the areas of special flood hazards or uses permitted within such areas will be free from flooding or flood damages. This ordinance shall not create liability on the part of the community or any official or employee thereof for any flood damages that result from reliance on this ordinance or any administrative decision lawfully made thereunder. DIVISION IV ADMINISTRATION SECTION A. DESIGNATION OF THE FLOODPLAIN ADMINISTRATOR The City Engineer is hereby appointed the Floodplain Administrator to administer and implement the provisions of this ordinance and other appropriate sections of 44 CFR (National Flood Insurance Program Regulations) pertaining to flood plain management. - 7 ORDINANCE NO. 927, PAGE 7 OF 18 SECTION B.

VARIANCE PROCEDURES (1) The Appeal Board as established by the community shall hear and render judgement on requests for variances from the requirements of this ordinance. (2) The Appeal Board shall hear and render judgement on an appeal only when it is alleged there is an error in any requirement, decision, or determination made by the Floodplain Administrator in the enforcement or administration of this ordinance. (3) Any person or persons aggrieved by the decision of the Appeal Board may appeal such decision in the courts of competent jurisdiction. (4) The Floodplain Administrator shall maintain a record of all actions involving an appeal and shall report variances to the Federal Emergency Management Agency upon request. (5) Variances may be issued for the reconstruction, rehabilitation or restoration of structures listed on the National Register of Historic Places or the State Inventory of Historic Places, without regard to the procedures set forth in the remainder of this ordinance. - 10 - ORDINANCE NO. 927, PAGE 10 OF 18 (6) Variances may be issued for new construction and substantial improvements to be erected on a lot of one -half acre or less in size contiguous to and surrounded by lots with existing structures constructed below the base flood level, providing the relevant factors in Section C(2) 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. (7) Upon consideration of the factors noted above and the intent of this ordinance, the Appeal Board may attach such conditions to the granting of variances as it deems necessary to further the purpose and objectives of this ordinance (Article 1, Section C). (8) Variances shall not be issued within any designated floodway if any increase in flood levels during the base flood discharge would result. (9) Prerequisites for granting variances: a. Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief. b. Variances shall only be issued upon, (i) showing a good and sufficient cause; (ii) a determination that failure to grant the variance would result in exceptional hardship to the applicant, 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 nuisances, cause fraud on or victimization of the public, or conflict with existing local laws or ordinances. C. Any application to whom a variance is granted shall be given written 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 elevation. (10) Variances may be issued by a community for new construction and substantial improvements and for other development necessary for the conduct of a functionally dependent use proved that (i) the criteria outlined in Article 4, Section D(1) -(9) are met, and (ii) the structure or other development is protected by methods that minimize flood damages during the base flood and create no additional threats to public safety. - 11 - ORDINANCE NO. 927, PAGE 11 OF 18 DIVISION V PROVISIONS FOR FLOOD HAZARD REDUCTION SECTION A. GENERAL STANDARDS In all areas of special flood hazards the following provisions are required for all new construction and substantial improvements. SECTION B. (1) All new construction or substantial improvements shall be designed (or modified) and adequately anchored to prevent flotation, collapse or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy; (2) All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage; (3) All new construction or substantial improvements shall be constructed with materials resistant to flood damage; (4) All new construction or substantial improvements shall be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and /or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

SPECIFIC STANDARDS In all areas of special flood hazards where base flood elevation data has been provided as set forth in (i) Article 3, Section B, (ii) Article 4, Section B(8), or (iii) Article 5, Section C(4), the following provisions are required: - 12 - ORDINANCE NO. 927, PAGE 12 OF 18 (1) Residential Construction - new construction and substantial improvement of any residential structure shall have the lowest floor (including basement), elevated two feet or more above the base flood elevation. A registered professional engineer, architect, or land surveyor shall submit a certification to the Floodplain Administrator that the standard of this subsection as proposed in Article 4, Section C(1)a., is satisfied. (2) Nonresidential Construction - new construction and substantial improvements of any commercial, industrial or other nonresidential structure shall either have the lowest floor (including basement) elevated two feet or more above the base flood level or, together with attendant utility and sanitary facilities, be designed 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 resisting hydrostatic and hydrodynamic loads and effects of buoyancy. A registered professional engineer or architect shall develop and /or review structural design, specifications, and plans for the construction, and shall certify that the design and methods of construction are in accordance with accepted standards of practice as outlined in this subsection. A record of such certification which includes the specific elevation (in relation to mean sea level) to which such structures are floodproofed shall be maintained by the Floodplain Administrator. (3) Enclosures - new construction and substantial improvements, with fully enclosed areas below the lowest floor that are subject to flooding shall be designed to automatically equalize hydrostatic flood forces on exterior walls by allowing for the entry and exit of floodwaters. Designs for meeting this requirement must either be certified by a registered professional engineer or architect or meet or exceed the following minimum criteria: a. A minimum of two openings having a total net area of not less than one square inch for every square foot of enclosed are subject to flooding shall be provided. b. The bottom of all openings shall be no higher than one foot above grade. C. Openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of floodwaters. (4) Manufactured Homes - a. The placement of manufactured housing within the areas which have been identified as regulatory floodways is prohibited. - 13 - ORDINANCE NO. 927, PAGE 13 OF 18 SECTION C. STANDARDS FOR SUBDMSION PROPOSALS (1) All subdivision proposals including manufactured home parks and subdivisions shall be consistent with Article 1, Sections B, C, and D of this ordinance. (2) All proposals for the development of subdivisions including manufactured home parks and subdivisions shall meet Development Permit requirements of Article 3, Section C; Article 4, Section C; and the provisions or Article 5 of this ordinance. (3) Base flood elevation data shall be generated for subdivision proposals and other proposed development including manufactured home parks and subdivisions which is greater than 30 lots or three acres, whichever is lesser, if not otherwise provided pursuant to Article 3, Section B or Article 4, Section B (8) of this ordinance. (4) All subdivision proposals including manufactured home parks and subdivisions shall have adequate drainage provided to reduce exposure to flood hazards. (5) All subdivision proposals including manufactured home parks and subdivisions shall have public utilities and facilities such as sewer, gas, electrical and water systems located and constructed to minimize or eliminate flood damage. SECTION D. STANDARDS FOR AREAS OF SHALLOW FLOODING (AO /AH ZONES) Located within the areas of special flood hazard established in Article 3, Section B, are areas designated as shallow flooding. These areas have special flood hazards associated with base flood depths of 1 to 3 feet where a clearly defined channel does not exist and where the path of flooding is unpredictable and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow; therefore, the following provisions apply; (1) All new construction and substantial improvements of residential structures have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least tow feet if no depth number is specified). (2) All new construction and substantial improvements of nonresidential structures; - 14 - ORDINANCE NO. 927, PAGE 14 OF 18 (i) have the lowest floor (including basement) elevated above the highest adjacent grade at least as high as the depth number specified in feet on the community's FIRM (at least two feet if no depth number is specified), or; (ii) together with attendant utility and sanitary facilities be designed 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 resisting hydrostatic and hydrodynamic loads of effects of buoyancy. (3) A registered professional engineer or architect shall submit a certification to the Floodplain Administrator that the standards of this Section, as proposed in Article 4, Section C (1)a., are satisfied. (4) Require within Zones AH or AO adequate drainage paths around structures on slopes, to guide flood waters around and away from proposed structures. SECTION E. FLOODWAYS Floodways - located within areas of special flood hazard established in Article 3, Section B, are areas designated as floodways. Since the floodway is an extremely hazardous area due to the velocity of flood waters which carry debris, potential projectiles and erosion potential, the following provisions shall apply; (1) Encroachments are prohibited, including fill, new construction, substantial improvements and other development unless certification by a professional registered engineer or architect is provided demonstrating that encroachments shall not result in any increase in flood levels within the community during the occurrence of the base flood discharge. (2) If Article 5, Section E (1) above is satisfied, all new construction and substantial improvements shall comply with all applicable flood hazard reduction provisions of Article 5. - 15 - ORDINANCE NO. 927, PACE 15 OF 18 DIVISION VI PENALTY FOR VIOLATION Any person, firm, corporation or agent who shall violate a provision of this regulation, or fail to comply therewith, or with any of the requirements thereof, or who shall erect, construct, or alter, any structure, or shall place any fill material, in violation of the detailed statement or drawing submitted and approved thereunder, shall be guilty of contempt of the Municipal Court of the City of Euless, Texas. Each such person shall be deemed guilty of a separate offense for each and every day, or portion thereof, during which any violation of any of the provisions of this regulation is committed, or continued. The Flood Plain Administrator is authorized to file with the Court Clerk a Motion suggesting contempt for failure to comply with these regulations. After filing, said Motion shall be presented to the City Judge who shall set a day and time for the Respondent to appear and show cause why he should not be held in contempt, which time shall not be less than ten (10) nor more than twenty (20) days from the date of filing of said Motion, whereupon the clerk shall issue a citation and notice of setting for service upon said Respondent. At said hearing Respondent shall be accorded the right to counsel, the right of confrontation, the right to summon and examine witnesses, and the right to testify and offer evidence in his behalf. If after such hearing before the Municipal Court he should be held in violation of the regulations and in contempt of the Orders of this Court as expressed in these regulations, then he may be punished by a fine not to exceed $1,000.00 for each offense or by imprisonment not to exceed twenty -four hours for each offense. DIVISION VII RIGHT OF ENTRY The Floodplain Administrator, or his duly authorized representative, may enter any building, structure, or premises to perform any duties imposed upon him by this regulation. DIVISION VII STOP WORK ORDERS Upon notice from the Floodplain Administrator that work on any building, structure, dike, bridge, or any improvement which would affect water drainage, is being done contrary to the provisions of the regulation, or in a dangerous or unsafe manner, such work shall be immediately stopped. Such notice shall be in writing and shall be given to the owner of the property or to his agent, or to the person doing the work, and shall state the conditions under which work may be resumed. Where an emergency exists, no written notice shall be required to be given by the Floodplain Administrator, provided, written notice shall follow within twenty -four (24) hours from the time oral notice to stop work is issued. - 16 - ORDINANCE NO. 927, PAGE 16 OF 18 DIVISION IX REVOCATION OF PERMIT The Floodplain Administrator may revoke a permit or approval issued under the provisions of this regulation, in cases where there has been any false statement or misrepresentation as to a material fact in the application or plans upon which the permit or approval was based. DIVISION X SEVERABILITY CLAUSE That it is hereby declared to be the intention of the City Council that the sections, paragraphs, sentences, clauses and phrases of this ordinance are severable, and if any phrase, clause, sentence, paragraph or section of this ordinance shall be declared unconstitutional by the valid judgment or decree of any court of competent jurisdiction, such unconstitutionality shall not affect any of the remaining phrases, clauses, sentences, paragraphs and sections of this ordinance, since the same would have been enacted by the City Council without the incorporation in this ordinance of any such unconstitutional phrase, clause, sentence, paragraph or section. DIVISION XI `u1JJu(�&JAul A V U This ordinance shall be in full force and effect from and after its passage and publication as provided by the Euless City Charter and the laws of the State of Texas. DIVISION XII CERTIFICATION It is hereby found and declared by the City of Euless, that severe flooding has occurred in the past within its jurisdiction and will certainly occur within the future; that flooding is likely to result in infliction of serious personal injury or death, and is likely to result in substantial injury or destruction of property within its jurisdiction; in order to effectively comply with minimum standards for coverage under the National Flood Insurance Program; and in order to effectively remedy the situation described herein, it is necessary that this ordinance become effective immediately. - 17 - ORDINANCE NO. 927, PAGE 17 OF 18 Therefore, this ordinance, being necessary for the immediate preservation of the public peace, health and safety, shall be in full force and effect from and after its passage and approval.
