In the absence of specific information, boundaries shall be determined by scaling distances on the map. Where interpretation is needed as to the exact location of the boundaries, the City Engineer shall make the necessary interpretation. In all cases, the level of the 100 year flood shall be the governing factor in locating the zone boundary on any property. Any person contesting the location of the zone boundary shall be given an opportunity to present his/her case to the Board of Adjustment for interpretation. (f) Disclaimer of liabilit . The degree of flood protection required herein is tons dere reasons a or regulatory purposes and is based on engineering and scientific methods of study. Larger floods may occur on rare occasions or flood heights may be increased by man-made or natural causes, such as ice jams or bridge openings restricted by debris. These regulations do not imply that areas outside the flood hazard overlay zones will be free from flooding or flood damages. These regulations shalt not create liability on the part of the City or any official or employee thereof for any flood damages that result from reliance on these regulations or any administrative decision lawfully made hereunder.

Upon reconstruction, the structure shall be adequately and safely flood roofed or elevated to the level of the 100 year flood as shown on the Flood Insurance Rate Map. (2) If a structure is located in the floodway fringe it may be recon- structed provided it IS adequately and safely flood-proofed or elevated in conformance with the requirements herein. (b) If any mobile home or mobile home park is destroyed by any means such that the cost of restoration would exceed 50% of its appraisal value prior to damage, then such mobile home or mobile home park shall not be rebuilt or replaced if it is located in the floodway. If it is located in the floodway fringe, it shall be rebuilt in conformance with the requirements herein. Sec. 36-37. Same - Variances. (a) General requirements for granting of a variance. In all circumstances variances may only be granted upon a determination that the variance issuance will not result in increased flood height, additional threats to public safety, extraordinary public expense, create nuisances, cause fraud or victimization of the public or conflict with any other local laws or ordinances. Variances shall not, under any condition, be issued within the floodway if any increase in flood level during the 100 year flood would result. (b) Insurance rates. The issuance of a variance to construct a building below theyeaRi r�oo level will result in increased premium rates for flood insurance coverage because such construction below the level of the 100 year flood increases risks to life and property. The applicant should contact his/her insurance agent for further information. (c) Approval b the Iowa Department of Water Air and Waste Management. All decis of ns o gran a variance s a e su mi e o e Iowa Department of Water, Air and Water Management for final approval.

In all instances where street right-of-way, which acts to separate the lots on which said uses are located, is one hundred (100) feet or wider, screening shall not be required. j (2) Screening materials. a. A planting screen of pyramidal arbor vitae, the plantings being at least three (3) feet high when planted and spaced four (4) feet on center, may be used. Other evergreen varieties may be used if approved by and spaced according to the City Forester. The planting bed shall have a minimum dimension of five (5) feet, be free of any impervious surface, and be separated from streets, i drives and parking areas by an unmountable curb or barrier in j such a manner that sand and saltwater runoff will not damage the screening. 1 b. Where a planting screen cannot be expected to thrive because of intense shade, soil and other conditions, a solid fence of durable construction, an earthen berm covered with grass or low shrubs and/or other acceptable materials which provide maximum visual obscurity to a height of six (6) feet at maturity may be used if approved by the City Forester. I (3) Time of installation. I a. If a lot proposed for a commercial or industrial use is located adjacent to or opposite an existing residential use or subdivi- sion in an R Zone, or a school, screening as required herein shall be installed prior to occupancy or commencement of a use.

It is the intent of this Chapter to regulate nonconforming uses and structures because they have been found to be incompatible with permitted uses and structures in the zone involved. However, single family uses shall not generally be treated as nonconforming uses. Nonconforming buildings shall be regulated to prevent an increase in the degree of nonconformity. The lawful use of any building or land existing on the effective date of this Chapter may continue although such use or land does not conform with the provisions of this Chapter: Sec. 36-79. General provisions. (a) Structural alterations. Structural alterations may be made to nonconfor- ming buildings to meet the minimum requirements of other city codes. (b) Unlawful use not authorized. Nothing in this Chapter shall be interpreted as au or H on or the continuance of the use of a structure or land estab- lished unlawfully in violation of the zoning regulations 1r, effect prior to the enactment of this Chapter. (c) Sin le famil dwe111n s treated as conforming. Notwithstanding any other provis on o s ap er, a s ng a ami y use, a single family dwelling and accessory structures, or a lot on which a single family dwelling is located, that was conforming prior to the effective date of this Chapter, shall gener- ally be treated as conforming for as long as the dwelling is used for a single family use. Accordingly, the following rights shall be granted under this Chapter: (1) Structures for a nonconforming single family use may be restored for a single family use if destroyed or damaged by fire, explosion, act of God, or by a public enemy; reconstructed; expanded; repaired; and structurally altered, provided all other requirements of this Chapter are met. (2) Nonconforming single family dwellings or nonconforming accessory structures to a single family use may be restored to the same degree of nonconformity or less if destroyed or damaged by fire, explosion, act of God, or by a public enemy; repaired; and structurally altered, provided such construction does not increase or extend the degree of nonconformity. Nonconforming structures shall not be reconstructed except in compliance with the provisions of this Chapter. (3) A nonconforming single family use and a nonconforming single family dwelling and accessory structures on a nonconforming lot shall be granted the same rights as above and any other rights as if the lot were conforming. (4) A nonconforming single family use and a nonconforming single family dwelling and accessory structures shall also be granted the same rights as for other nonconforming uses and structures. 1053 i ■ I .F 158 Sec. 36-80. Nonconforming uses. Except as otherwise provided in this Chapter, nonconforming uses and structures for nonconforming uses shall be regulated as follows: (a) No nonconforming use shall be enlarged nor shall a structure for a nonconforming use be constructed, reconstructed, structurally altered, or relocated on the lot. (b) A nonconforming use may be converted only to a conforming use. Once a use is converted to a conforming use, it shall not be converted back to a noncon- forming use. (c) Any structure for a nonconforming use, which has been destroyed or damaged by fire, explosion, act of God, or by a public enemy to the extent of less than 100% of the structure's assessed value, may be restored for the same nonconfor- minguse as existed before such damage. However, the nonconforming use shall not be enlarged to more than existed before such damage. j (d) A lot or portion of a lot, on which is located a structure for a noncon- forring use that has been destroyed or damaged by fire, explosion, act of God, j or by a public enemy to the extent of 100% 6r more of the structure's assessed j value, shall revert to a conforming use. I I (e) A lot or portion of a lot devoted to a nonconforming use, which is discontinued for a period of one (1) year, shall revert to a conforming use. (f) A nonconforming use shall be permitted to have the same amount and type of signage as would be allowed for such use in the most restrictive zone in which such nonconforming use is allowed. Sec. 36-81. Nonconforming structures. Nonconforming structures shall be regulated as follows: (a) Any nonconforming structure, which has been destroyed or damaged by fire, explosion, act of God, or by a public enemy to the extent of less than 100% of 1 the structure's assessed value, may be restored to the same degree of non- conformity or less. (b) Except for buildings in an Historic Preservation Overlay Zone, a noncon- forming structure, which has been destroyed or damaged by fire, explosion, act of God, or by a public enemy to the extent of 100% or more of the structure's assessed value, shall not be restored except in compliance with the provisions of this Chapter. A nonconforming building in an Historic Preservation Overlay Zone may be placed upon its original foundation or the site of the original foundation regardless of the extent of damage provided that it is reconstructed as near as possible to the original exterior design. (c) Any nonconforming structure containing a conforming use may be converted to another conforming use, provided there shall not result an increase in the I. degree of nonconformity of the structure. I 1,053 S fi 159 (d) A nonconforming structure may be structurally altered, provided it is structurally altered in a way which will not increase or extend its noncon- formity or in a way which will reduce its nonconformity. (e) Any nonconforming structure which is relocated on the same lot shall thereafter conform to the provisions of this Chapter. Sec. 36-82. Nonconforming lots. Development of nonconforming lots shall be regulated as follows: (a) Any use or structure for a use permitted in the zone in which the lot is located may be established or erected, provided the use or structure meets all other requirements of this Chapter. However, no use nor structure for a use, either one of which requires more lot area than presently exists, shall be permitted. (b) All existing conforming or nonconforming uses and structures shall be treated as if such uses and structures were established on a conforming lot. However, no use nor structure for a use, either one of which requires more lot area than presently exists and the structure of which has been destroyed or damaged by fire, explosion, act of God, or by a public enemy to the extent of 100% or more of the structure's assessed value, shall be restored except in compliance with the provisions of this Chapter. (c) If two or more abutting lots or portions thereof become in single owner- ship, the land involved shall be deemed a single parcel for the purposes of this Chapter and no portion of said parcel shall be sold or used in a manner which diminishes compliance with lot frontage, width and area requirements.

Jansen, City Attorney 4(\ RE:Council Vote on June 4th Re-enacting Comprehensive Zoning Ordinance and Map Question has arisen concerning the validity of the Council vote on June 4th when the zoning ordinance and map were re -adopted by the Council. Councilmember Erdahl moved for suspension of the rule requiring that an ordinance must be considered and voted on for passage at three consecutive meetings. On roll call vote; all members voted to suspend the rule thus permitting a vote for iffuueu.ia w yaoaage. Following this vote, Mr. Erdahl then moved to separate the voting on the text and the map. Following this motion, roll call vote was had on adoption of the text. Unanimous. Motion by Erdahl then followed to move final adoption of the map as presented (by Planning and zoning) with RS -8 zoning designated for the area north of Shimek School. This would have been a downzoning from RS -12 to RS -8 thus necessitating a three-fourths majority under state law requirements since the property owners had objected. Motion for passage failed (3-4). Erdahl then moved adoption of the map which designates the area north of Shimek School as RS -12. Since this did not involve downzoning, a simple.majority vote was required for passage. The vote for passage failed (4-3). Somewhat confused discussion among the Councilmembers then ensued. Mr. Erdahl then again moved passage of the map with the area north of Shimek School designated RS -12. Vote for passage was 5-2 and the ordinance passed. A Councilmember has now raised the question that if the Council votes to suspend the rule requiring passage of an ordinance at three consecutive meetings, which requires a three -fourth majority vote of the members of the Council, does the ordinance -itself then require a three-fourths vote for passage? The answer is no. The applicable statutes are as -follows: Iowa Code, Sec. 383.: A proposed ordinance or amendment must bs cconsidered and voted on for passage at two council meetings prior to the meeting at which it is to be finally passed unless this requirement is suspended by a recorded vote of not less than three-fourths of the councilmembers. /053 Mayor McDonald, City Manager, City Clerk and Karin Franklin June 7, 1955 Page 2 Sec. 2.11 of the City Charter provides: A. Passage of an ordinance, amendment or resolution requires an affirmative vote of a majority of the Councilmembers except as otherwise provided by State law. Iowa Code, Sec. 414.5 provides: The (zoning) regulations, restrictions, and boundaries may, from time to time, be amended, supplemented, changed, modified, or repealed. In case, however, of a written protest against a. change or repeal which is filed by the City.Clerk and signed by the owners of 208 or more of the area of the.lots included in the proposed change or repeal, or by the owners'of 208 or more of the property which is located within 200 feet r;f the =xterior bcundaries of tile property for which the change or repeal�is proposed, the change or repeal shall not become effective except by a, favorable vote of at least three- fourths of all of the members of the council. In my opinion Sec. 380.3 of the Iia Code, above set out, only Provides a mechanism for the Council EO—dispense with the state law requirement that an ordinance is not effectively enacted unless it is given three separate considerations at three separate council meetings. This Code section does not contain any requirement that the ordinance tself must also receive a three -fourth vote for passage. Even though the adoption of the map is a zoning measure, zoning ordinances never require a three- fourths vote.unless they involve a change in zoning and the property owners object. As provided in Sec. 411.5 of the Iowa Code as set out above, Mr. Glasgow, the owner, only objected to the RS -12 designation which was defeated because the three -fourth vote requirement failed. As also set forth in the City Charter provision quoted above, all ordinances or amendments simply require a majority vote unless otherwise provided by state law, for example, Sec. 414.5 of the Iowa Code also set out above. I Code Sec. 380.3 is a statutory rule of procedure. State v. Central States Elec. Co., 28 NW2d 457 (Iowa 1947). As such, a procedural rule only sets forth the procedure to be followed and does not deal with the substantive aspect that the rule is designed to govern. In other words, Iowa Code Sec. 380.3 simply allows the Council to suspend the three rea ng -three meeting rule as a means of quicker passage of ordinances. It does not go i I ' Mayor McDonald, City Manager, City Clerk and Karin Franklin June 7, 1985 Page 3 r I I I � i beyond that to require that the ordinance itself also requires a three—fourths vote for passage. As a practical matter the Council often gives an ordinance all three readings and the following vote on the ordinance is .i unanimous. This is simply because if the Council agrees to allow three readings the Council is usually unanimous on the vote on the ordinance itself. However,. this is not to be taken as established policy or precedent. .�. _.... i -..:_]D I I I I. i 1653 i 1 t0 1 � Q I N N. 7` q Ft 0 G r +N W Vie. 1� L: of e All. V^ R tys 3, tt �.
