BE IT ORDAINED by the Governing Body of the City of Salina, Kansas: Section 1. That Article VIII of Chapter 42 of the Salina Code is hereby amended to read as follows: "ARTICLE Vill. FLOOD PLAIN ZONING DISTRICT DIVISION 1. STATUTORY AUTHORIZATION, FINDINGS OF FACT AND PURPOSES "Sec. 42-426. Statutory authorization. (I The Legislature of the State of Kansas has in K.S.A. 12-705, 12-707, 12-710, 12-734 and 12-735 delegated the responsibility to local governmental units to adopt zoning regulations designed to protect the public health, safety and general welfare. "Sec. 42-427. Findinqs of fact. (a) Flood losses resulting from periodic inundation. The flood hazard areas of the City of Salina, Kansas are subject to inundation which may 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. (b) General causes of these flood losses. These flood losses are caused by: (1) The cumulative effect of obstruction in floodways causing increases in flood heights and velocities; and (2) The occupancy of flood hazard areas by uses vulnerable to floods or hazardous to others which are inadequately elevated or otherwise unprotected from flood damages. (c) Methods used to analyze flood hazards. This article uses a reasonable method of analyzing flood hazards which consists of a series of interrelated steps. (1 ) Selection of a base flood which is based upon engineering calculations which permit a consideration of such flood factors as its expected frequency of occurrence, the area inundated, and the depth of inundation. The base flood selected for this ordinance is representative of large floods 1 1 1 which are reasonably characteristic of what can be expected to occur on the particular streams subject to this ordinance. It is in the general order of a flood which could be expected to have a one (1) percent chance of occurrence in any one year, as delineated on the Federal Emergency Management Agency's Flood Insurance Study, and illustrative materials dated February 5, 1986 as amended, and any future changes thereto. (2) Calculation of water surface profiles based upon a hydraulic engineering analysis of the capacity of the stream channel and overbank areas to convey the base flood. (3) Computation of the floodway required to convey this flood without increasing flood heights more than one (1) foot at any point. (4) Delineation of floodway encroachment lines within which no obstruction is permitted which would cause any increase in flood height. (5) Delineation of floodway fringe, i.e. , that area outside the floodway encroachment lines but which still is subject to inundation by the base flood. "Sec. 42-428. Statement of purpose. It is the purpose of this article to promote and protect the public health, safety and general welfare and to minimize those losses described in Section 42-427(a) by applying the provisions of this article to: (a) Restrict or prohibit uses which are dangerous to health, safety, or property in times of flooding or cause undue increases in flood heights or velocities. (b) Require that uses vulnerable to floods, including public facilities which serve such uses, be provided with flood protection at the time of initial construction. (c) Protect individuals from buying lands which are unsuited for certain purposes because of flood hazard. (d) Assure that eligibility is maintained for property owners in the community to purchase flood insurance in the National Flood Insurance Program. "DIVISION 2. GENERAL PROVISIONS "Sec. 42-429. Lands to which the article applies. (a) The Flood Insurance Study of the City of Salina, Kansas (Effective Date: February 5, 1986) including the Flood Boundary and Floodway Map (Floodway Map) and the Flood Insurance Rate Map (FIRM) issued by the Federal Emergency Management Agency is hereby adopted and incorporated by reference for the purpose of identifying all lands within the jurisdiction of the City of Salina, Kansas, to which this article shall apply. Not fewer than three (3) copies of the Flood Insurance Study adopted above have been filed in both the Office of the City Clerk and the Office of the Zoning Administrator and are available for examination by the public during normal office hours. (b) This article shall apply to all lands within the jurisdiction of the City of Salina, Kansas identified on the Flood Insurance Rate Map (FIRM) as numbered and unnumbered A Zones (including the AH zone) and within the Zoning Districts FW and FF established in Division 4 of this article. In all areas covered by this 1 1 article, no development shall be permitted except upon issuance of a permit to develop granted by the City of Salina or its duly designated representative under such safeguards and restrictions as the City of Salina or the designated representative may reasonably impose for the promotion and maintenance of the general welfare, health and safety of the inhabitants of the community and where specifically noted in Divisions 5, 6 and 7. "Sec. 42-430. Rules for interpretation of district boundaries. (a) The boundaries of the floodway (FW) and floodway fringe (FF) overlay districts shall be determined by scaling distances on the official zoning map or on the Flood Insurance Rate Map or Floodway Map. Where interpretation is needed to determine the exact location of the boundaries of the districts as shown on the official zoning map, as for example where there appears to be a conflict between a mapped boundary and actual field conditions, the Zoning Administrator shall make the necessary interpretation. In such cases where the interpretation is contested, the Board of Zoning Appeals will resolve the dispute. The base flood elevation for the point in question shall be the governing factor in locating the district boundary on the land. The person contesting the location of the district boundary shall be given a reasonable opportunity to present his case to the Board and to submit his own technical evidence, if he so desires. (b) Any flood plain district designated on the official zoning map pursuant to prior ordinance shall be lifted from the official zoning map and shall be of no further force or effect. "Sec. 42-431. Compliance. No development located within known flood hazard areas of this community shall be located, extended, converted or structurally altered without full compliance with the terms of this article and other applicable regulations. "Sec. 42-432. Warning and disclaimer of liability. The degree of flood protection required by this article is considered reasonable for regulatory purposes and is based on engineering and scientific methods of study. Larger floods may occur on rare occasions or the flood height may be increased by man made or natural causes, such as ice jams and bridge openings restricted by debris. This article does not imply that areas outside floodway and floodway fringe district boundaries or land uses permitted within such districts will be free from flooding or flood damages. This article shall not create liability on the part of the City of Salina, Kansas or any officer or employee thereof for any flood damages that may result from reliance on this article or any administrative decision lawfully made thereunder. "Sec. 42-433. Appeal. Where a request for a permit to develop is denied by the Zoning Administrator the applicant may appeal such denial for such permit directly to the Board of Zoning Appeals. "DIVISION 3. DEVELOPMENT PERMIT "Sec. 42-434. Permit required.

(3) Notification of adjacent communities and the Division of Water Resources, Kansas State Board of Agriculture prior to any alteration or relocation of a watercourse, and evidence shall be submitted of such notification to the Federal Emergency Management Agency. (4) Assurance that maintenance is provided within the altered or relocated portion of said watercourse so that the flood carrying capacity is not diminished. (5) Verification, recording and maintenance of records of the actual elevation (in relation to mean sea level) of the lowest floor (including basement) of all new or substantially improved structures. (6) Verification, recording and maintenance of records of the actual elevation (in relation to mean sea level) to which the new or substantially improved structures have been floodproofed. (7) Obtaining certification from a registered professional engineer or architect when floodproofing is utilized for a particular structure. "Sec. 42-436. Application for permit. To obtain a permit, the applicant shall first file an application in writing on a form furnished for that purpose. Every such application shall: (a) Identify and describe the work to be covered by the permit. (b) Describe the land on which the proposed work is to be done by lot, block, tract and house and street address, or similar description that will readily identify and definitely locate the proposed building or work. (c) Indicate the use or occupancy for which the proposed work is intended. (d) Be accompanied by plans and specifications for proposed construction. (e) Be signed by the permitee or his authorized agent who may be required to submit evidence to indicate such authority. (f) Give such other information as reasonably may be required by the Zoning Administrator. "DIVISION 4. ESTABLISHMENT OF ZONING DISTRICTS "Sec. 42-437. Establishment of zoning districts. The mapped flood plain areas within the jurisdiction of this article are hereby divided into the two following districts: a floodway overlay district (FW) and a floodway fringe overlay district (FF) identified in the Flood Insurance Study [and accompanying maps(s) ). Within these districts all uses not meeting the standards of this article and those standards of the underlying zoning district shall be prohibited.

"Sec. 42-445. Findings required. Variances shall not be issued except upon: (a) a showing of good and sufficient cause, The Zoning Administrator shall notify the applicant that the issuance of a variance to locate a structure at an elevation below the 100 -year flood level will result in increased rates for flood insurance coverage. The Applicant will provide written and notarized acknowledgement of such notification. (b) a determination that failure to grant the variance would result in exceptional hardship to the applicant, and (c) a determination that the variance issuance 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 ordinances or state laws, particularly K.S.A. 12-734. "Sec. 42-446. Determination of minimum standards. Variances may only be issued upon a determination that the applicant requesting a variance shall meet the minimum necessary standards of this article to afford relief. "Sec. 42-447. Notification of increased insurance rates. The Zoning Administrator shall notify the applicant that the issuance of a variance to locate a structure at an elevation below the 100 -year flood level will result in increased rates for flood insurance coverage.
