AN ORDINANCE FOR THE MANAGEMENT OF FLOODPLAINS IN THE CITY OF ANDOVER, ANOKA COUNTY, MINNESOTA. The City Council of the City of Andover hereby ordains as follows: SECTION: 14 -1 -1: Statutory Authorization 14 -1 -2: Findings of Fact 14 -1 -3: Purpose 14 -1 -4: General Provisions 14 -1 -5: Definitions 14 -1 -6: Establishment of Zoning Districts 14 -1 -7: Floodway District(FW) 14 -1 -8: Flood Fringe District (FF) 14 -1 -9: General Floodplain District (GF) 14 -1 -10: Land Development Standards 14 -1 -11: Public Utilities, Railroads, Roads, and Bridges 14 -1 -12: Manufactured Homes, Manufactured Home Parks, and Recreational Vehicles 14 -1 -13: Administration 14 -1 -14: Penalties and Enforcement 14 -1 -15: Amendments 14-1 -1 STATUTORY AUTHORIZATION The legislature of the State of Minnesota has, in Minnesota Statutes Chapter 103F and Chapter 462 delegated the responsibility to local government units to adopt regulations designed to minimize flood losses. Therefore, the City Council of Andover, Minnesota, does ordain the provisions of this chapter. 14-1 -2 FINDINGS OF FACT A. This ordinance regulates development in the flood hazard areas of Andover, Minnesota. These flood hazard areas are subject to periodic 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. It is the purpose of this ordinance to promote the public health, safety, and general welfare by minimizing these losses and disruptions. B. National Flood Insurance Program Compliance. This ordinance is adopted to comply with the rules and regulations of the National Flood Insurance Program codified as 44 Code of Federal Regulations Parts 59 -78, as amended, so as to maintain the community's eligibility in the National Flood Insurance Program. 14-1 -3 PURPOSE This ordinance is also intended to preserve the natural characteristics and functions of watercourses and floodplains in order to moderate flood and stonnwater impacts, improve water quality, reduce soil erosion, protect aquatic and riparian habitat, provide recreational opportunities, provide aesthetic benefits and enhance community and economic development. 14 -1-4 GENERAL PROVISIONS A. This ordinance adopts the floodplain maps applicable to Andover and includes three floodplain districts: Floodway, Flood Fringe, and General Floodplain. 1. Where Floodway and Flood Fringe districts are delineated on the floodplain maps, the standards in Sections 14 -1 -7 and 14 -1 -8 will apply, depending on the location of a property. 2. Locations where Floodway and Flood Fringe districts are not delineated on the floodplain maps are considered to fall within the General Floodplain district. Within the General Floodplain district, the Floodway District standards in Section 14 -1 -7 apply unless the floodway boundary is determined, according to the process outlined in Section 14-1-9. Once the floodway boundary is determined, the Flood Fringe District standards in Section 14 -1 -8 may apply outside the floodway. B. Lands to Which Ordinance Applies: This ordinance applies to all lands within the jurisdiction of the City of Andover shown on the Official Zoning Map and/or the attachments to the map as being located within the boundaries of the Floodway, Flood Fringe, or General Floodplain Districts. The Floodway, Flood Fringe and General Floodplain Districts are overlay districts that are superimposed on all existing zoning districts. The standards imposed in the overlay districts we in addition to any other requirements in this ordinance. In case of a conflict, the more restrictive standards will apply. C. Incorporation of Maps by Reference: The following maps together with all attached material are hereby adopted by reference and declared to be a part of the Official Zoning Map and this ordinance. The attached material includes the Flood hnsmance Study for Anoka County, Minnesota, and Incorporated Areas and the Flood Insurance Rate Map panels enumerated below, all dated December 16, 2015 and all prepared by the Federal Emergency Management Agency. These materials are on file in the office of the Andover Community Development Department. 27003CO282E 27003CO301E 27003CO166E 27003CO302E 27003CO167E 27003CO303E 27003CO170E 27003CO304E 27003CO186E 27003CO306E 27003CO187E 27003CO307E 27003CO190E 27003CO308E 27003CO195E 27003CO309E October 2015 D. Regulatory Flood Protection Elevation: The regulatory flood protection elevation (RFPE) is an elevation no lower than one foot above the elevation of the regional flood plus any increases in flood elevation caused by encroachments on the floodplain that result from designation of a floodway. E. Interpretation: The boundaries of the zoning districts are determined by scaling distances on the Flood Insurance Rate Map. 1. Where a conflict exists between the floodplain limits illustrated on the official zoning map and actual field conditions, the flood elevations shall be the governing factor. The Zoning Administrator most interpret the boundary location based on the ground elevations that existed on the site on the date of the first National Flood Insurance Program map showing the area within the regulatory floodplain, and other available technical data. 2. Persons contesting the location of the district boundaries will be given a reasonable opportunity to present their case to the Planning and Zoning Commission/Board of Adjustment and to submit technical evidence. F. Abrogation and Greater Restrictions: It is not intended by this ordinance to repeal, abrogate, or impair any existing easements, covenants, or other private agreements. However, where this ordinance imposes greater restrictions, the provisions of this ordinance prevail. All other ordinances inconsistent with this ordinance are hereby repealed to the extent of the inconsistency only. G. Warning and Disclaimer of Liability: This ordinance does not imply that areas outside the floodplain districts or land uses permitted within such districts will be free from flooding or flood damages. This ordinance does not create liability on the part of the City of Andover or its officers or employees for any flood damages that result from reliance on this ordinance or any administrative decision lawfully made hereunder. H. Severability: If any section, clause, provision, or portion of this ordinance is adjudged unconstitutional or invalid by a court of law, the remainder of this ordinance shall not be affected and shall remain in full force. 14 -1 -5 Definitions: Unless specifically defined below, words or phrases used in this ordinance must be interpreted according to common usage and so as to give this ordinance its most reasonable application. Accessory Use or Structure — a use or structure on the same lot with, and of a nature customarily incidental and subordinate to, the principal use or structure. Base Flood Elevation — The elevation of the "regional flood." The tern "base flood elevation" is used in the flood insurance survey. Basement —any area of a structure, including crawl spaces, having its floor or base subgmde (below ground level) on all four sides, regardless of the depth of excavation below ground level. Conditional Use — a specific type of structure or land use listed in the official control that may be allowed but only after an in -depth review procedure and with appropriate conditions or restrictions as provided in the official zoning controls or building codes and upon a finding that: (a) Certain conditions as detailed in the zoning ordinance exist. (b) The structure and/or land use conform to the comprehensive land use plan if one exists and are compatible with the existing neighborhood. Critical Facilities — facilities necessary to a community's public health and safety, those that store or produce highly volatile, toxic or water - reactive materials, and those that house occupants that may be insufficiently mobile to avoid loss of life or injury. Examples of critical facilities include hospitals, correctional facilities, schools, daycare facilities, nursing homes, fire and police stations, wastewater treatment facilities, public electric utilities, water plants, fuel storage facilities, and waste handling and storage facilities. Development —any mamnade change to improved or unimproved real estate, including buildings or other structures, mining, dredging, filling, grading, paving, excavation or drilling operations, or storage of equipment or materials. Equal Degree of Encroachment — a method of determining the location of floodway boundaries so that floodplain lands on both sides of a stream are capable of conveying a proportionate share of flood flows. Farm Fence — A fence as defined by Minn. Statutes Section 344.02, Subd. l(a)-(d). An open type fence of posts and wire is not considered to be a structure under this ordinance. Fences that have the potential to obstruct flood flows, such as chain link fences and rigid walls, are regulated as structures under this ordinance. Flood — a temporary increase in the flow or stage of a stream or in the stage of a wetland or lake that results in the inundation of normally dry areas. Flood Frequency — the frequency for which it is expected that a specific flood stage or discharge may be equaled or exceeded. Flood Fringe — that portion of the floodplain outside of the floodway. Flood fringe is synonymous with the term "floodway fringe" used in the Flood Insurance Study for Anoka County, Minnesota. Flood Prone Area —any land susceptible to being inundated by water from any source (see `Flood'). Floodplain — the beds proper and the areas adjoining a wetland, lake or watercourse which have been or hereafter may be covered by the regional flood. Floodproofmg — a combination of structural provisions, changes, or adjustments to properties and structures subject to flooding, primarily for the reduction or elimination of flood damages. Floodway — the bed of a wetland or lake and the channel of a watercourse and those portions of the adjoining floodplain which are reasonably required to carry or store the regional flood discharge. Lowest Floor — the lowest floor of the lowest enclosed area (including basement). An unfinished or flood resistant enclosure, used 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. Manufactured Home — 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 attached to the required utilities. The term "manufactured home" does not include the term "recreational vehicle" Obstruction —any dam, wall, wharf, embankment, levee, dike, pile, abutment, projection, excavation, channel modification, culvert, building, wire, fence, stockpile, refuse, fill, structure, or matter in, along, across, or projecting into any channel, watercourse, or regulatory floodplain which may impede, retard, or change the direction of the flow of water, either in itself or by catching or collecting debris carried by such water. One Hundred Year Floodplain — lands inundated by the "Regional Flood" (see definition). Principal Use or Structure — all uses or structures that are not accessory uses or structures. Reach — a hydraulic engineering terra to describe a longitudinal segment of a stream or river influenced by a natural or man-made obstruction. In an urban area, the segment of a stream or river between two consecutive bridge crossings would most typically constitute a reach. Recreational Vehicle — a vehicle that is built on a single chassis, is 400 square feet or less when measured at the largest horizontal projection, is designed to be self-propelled or permanently towable October2015 by a light duty truck, and is designed primarily not for use as a permanent dwelling but as temporary living quarters for recreational, camping, travel, or seasonal use. For the purposes of this ordinance, the term recreational vehicle is synonymous with the term "travel trailer /travel vehicle." Regional Flood — a flood which is representative of large floods known to have occurred generally in Minnesota and reasonably characteristic of what can be expected to occur on an average frequency in the magnitude of the 1% chance or 100 -year recurrence interval. Regional flood is synonymous with the term "base flood' used in a flood insurance study. Regulatory Flood Protection Elevation (RFPE) - an elevation not less than one foot above the elevation of the regional flood plus any increases in flood elevation caused by encroachments on the floodplain that result from designation of a floodway. Repetitive loss: Flood related damages sustained by a structure on two separate occasions during a ten year period for which the cost of repairs at the time of each such flood event on the average equals or exceeds 25% of the market value of the structure before the damage occurred. Special Flood Hazard Area — a tern used for flood insurance purposes synonymous with "One Hundred Year F000dplain." Structure - anything constructed or erected on the ground or attached to the ground or on -site utilities, including, but not limited to, buildings, factories, sheds, detached garages, cabins, manufactured homes, recreational vehicles not meeting the exemption criteria specified in Section 9.22 of [his ordinance and other similar items. Substantial Damage - means damage of any origin sustained by a structure where the cost of restoring the structure to its before damaged condition would equal or exceed 50 percent of the market value of the structure before the damage occurred. Substantial Improvement - within any consecutive 365 -day period, any reconstruction, rehabilitation (including normal maintenance and repair), repair after damage, addition, or other improvement of a structure, the cost of which equals or exceeds 50 percent of the market value of the structure before the "start of construction" of the improvement. This term includes structures that have incurred "substantial damage," regardless of the actual repair work performed. The term does not, however, include either: (a) Any project for improvement of a structure to correct existing violations of state or local health, sanitary, or safety code specifications which have been identified by the local code enforcement official and which are the minimum necessary to assure safe living conditions. (b) Any alteration of a "historic structure," provided that the alteration will not preclude the structure's continued designation as a "historic structure." For the purpose of this ordinance, "historic structure" is as defined in 44 Code of Federal Regulations, Par 59.1. A. Annexations: The Flood Insurance Rate Map panels adopted by reference into Section 14 -1 4(c) above may include floodplain areas that lie outside of the corporate boundaries of the City of Andover at the time of adoption of this ordinance. If any of these floodplain land areas are annexed into the City after the date of adoption of this ordinance, the newly annexed floodplain lands will be subject to the provisions of this ordinance immediately upon the date of annexation. 14 -1 -6 ESTABLISHMENT OF ZONING DISTRICTS A. Districts: Floodway District. The Floodway District includes those areas designated as floodway on the Flood Insurance Rate Map adopted in Section 14 -1 -0C. For lakes, wetlands and other basins, the Floodway District includes those areas designated as Zone A and Zone AE without a floodway on the Flood Insurance Rate Map that are at or below the ordinary high water level as defined in Minnesota Statutes, Section 103G.005, subdivision 14.

Fill, dredge spoil, and other similar materials deposited or stored in the floodplain most be protected from erosion by vegetative cover, mulching, riprap or other acceptable method. Pemtanent sand and gravel operations and similar uses must be covered by a long -term site development plan. 3. Temporary placement of fill, other materials, or equipment which would cause an increase to the stage of the 1 % percent chance or regional flood may only be allowed if the City Council has approved a plan that assures removal of the materials from the floodway based upon the flood wanting time available. 3. Accessory Structures: (a) Accessory structures must not be designed for human habitation. (b) Accessory structures, if permitted, must be constructed and placed on the building site an as to offer the minimum obstruction to the flow of flood waters: October 2015 (1) Whenever possible, structures must be constructed with the longitudinal axis parallel to the direction of flood flow; and (2) So far as practicable, structures must be placed approximately on the same flood flow lines as those of adjoining structures.

(d) As an alternative, an accessory structure may be internally /wet floodpmofed to the FP -3 or FP-4 floodproofng classifications in the State Building Code, provided the accessory structure constitutes a minimal investment and does not exceed 576 square feet in size. A detached garage may only be used for parking of vehicles and limited storage. All structures must meet the following standards: (1) To allow for the equalization of hydrostatic pressure, there must he a minimum of two "automatic° openings in the outside walls of the structure, with a total net area of not less than one square inch for every square foot of enclosed area subject to flooding; and (2) There must be openings on at least two sides of the structure and the bottom of all openings must be no higher than one foot above the lowest adjacent grade to the structure. Using human intervention to open a garage door prior to flooding will not satisfy this requirement for automatic openings. 4. Structural works for flood control that will change the course, current or cross section of protected wetlands or public waters are subject to the provisions of Minnesota Statutes, Section 103G.245. 5. A levee, dike or floodwall constructed in the floodway most not cause an increase to the I% chance or regional flood. The technical analysis must assume equal conveyance or storage loss on both sides of a stream. 6. Floodway developments must not adversely affect the hydraulic capacity of the charnel and adjoining floodplain of any tributary watercourse or drainage system. 14-1-8 FLOOD FRINGE DISTRICT (IT) A. Permitted Uses: 1. Permitted uses are those uses of land or structures allowed in the underlying zoning district(s) that comply with the standards in Sections 14- 1- 8A(2).

Standards for Flood Fringe Permitted Uses: A. All structures, including accessory structures, must be elevated on fill so that the lowest floor, as defined, is at or above the regulatory flood protection elevation. The finished fill elevation for structures must be no lower than one foot below the regulatory flood protection elevation and the fill must extend at the same elevation at least 15 feet beyond the outside limits of the structure. October 2015 5 1. All service utilities, including ductwork, must be elevated or water -tight to prevent infiltration of floodwaters. 2. As an alternative to elevation on fill, an accessory structure that constitutes a minimal investment and that does not exceed 576 square feet in size may be internally floodproofed in accordance with Section 14- I- 7B(3). B. The cumulative placement of fill or similar material on a parcel must not exceed 1,000 cubic yards, unless the fill is specifically intended to elevate a structure in accordance with Section 14- 1 -8A(2) A of this ordinance, or if allowed as a conditional use under Section 14- 1 -8B(3) below. C. The storage of any materials or equipment must be elevated on fill to the regulatory flood protection elevation. D.

Standards for Flood Fringe Conditional Uses: 1. The standards listed in Sections 14- 1 -8A(2) apply to all conditional uses. 2. Basements, as defined by Section 14 -1 -15 of this ordinance, are subject to the following: October 2015 (a) Residential basement construction is not allowed below the regulatory flood protection elevation. (b) Non - residential basements may be allowed below the regulatory flood protection elevation provided the basement is structurally dry floodproofed in accordance with Section 14-1 - 8C(4) of this ordinance. 3. All areas of nonresidential structures, including basements, to be placed below the regulatory flood protection elevation must be floodproofed in accordance with the structurally dry floodproofmg classifications in the State Building Code. Structurally dry floodproofmg must meet the FP -1 or FP -2 floodproofmg classification in the State Building Code, which requires making the structure watertight with the walls substantially impermeable to the passage of water and with smictum] components capable of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy. Structures wet floodproofed to the FP -3 or FP-4 classification are not permitted. 4. The placement of more than 1,000 cubic yards of fill or other similar material on a parcel (other than for the purpose of elevating a structure to the regulatory flood protection elevation) must comply with an approved erosion/sedimentation control plan. (a) The plan must clearly specify methods to be used to stabilize the fill on site for a flood event at a minimum of the regional (1% chance) flood event.

(c) The plan may incorporate alternative procedures for removal of the material from the floodplain if adequate flood warning time exists. 5. Storage of materials and equipment below the regulatory flood protection elevation must comply with an approved emergency plan providing for removal of such materials within the time available after a flood warning. 6. Alternative elevation methods other than the use of fill may be utilized to elevate a structure's lowest floor above the regulatory flood protection elevation. These alternative methods may include the use of stilts, pilings, parallel walls, etc., or above - grade, enclosed areas such as crawl spaces or tuck under garages. The base or floor of an enclosed area shall be considered above -grade and not a structure's basement or lowest floor if. 1) the enclosed area is above - grade on at least one side of the structure; 2) it is designed to internally flood and is constructed with flood resistant materials; and 3) it is used solely for parking of vehicles, building access or storage. The above -noted alternative elevation methods are subject to the following additional standards: (a) Design and Certification - The structure's design and as -built condition must be certified by a registered professional engineer or architect as being in compliance with the general design standards of the State Building Code and, specifically, that all electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities most be at or above the regulatory flood protection elevation or be designed to prevent flood water from entering or accumulating within these components during times of flooding. (b) Specific Standards for Above - grade, Enclosed Areas - Above -grade, fully enclosed areas such as crawl spaces or tuck under garages must be designed to internally flood and the design plans must stipulate: (1) The minimum area of openings in the walls where internal flooding is to be used as a floodproofmg technique. There shall be a minimum of two openings on at least two sides of the structure and the bottom of all openings shall be no higher than one foot October 2015 above grade. The automatic openings shall have a minimum net area of not less than one square inch for every square foot of enclosed area subject to flooding unless a registered professional engineer or architect certifies that a smaller net area would suffice. The automatic openings may be equipped with screens, louvers, valves, or other coverings or devices provided that they permit the automatic entry and exit of flood waters without any form of human intervention; and (2) That the enclosed area will be designed of flood resistant materials in accordance with the FP -3 or FP-4 classifications in the State Building Code and shall be used solely for building access, parking of vehicles or storage. 14 -1 -9 GENERAL FLOODPLAIN DISTRICT (GF) A. Permitted Uses: 1. The uses listed in Section 14 -1 -7A of this ordinance, Floodway District Permitted Uses, are permitted uses. 2. All other uses are subject to the floodway /flood fringe evaluation criteria specified in Section 14 -1 -913 below. Section 14 -1 -7 applies if the proposed use is determined to be in the Floodway District. Section 14 -1 -8 applies if the proposed use is determined to be in the Flood Fringe District. B. Procedures for Floodway and Flood Fringe Determinations: 1. Upon receipt of an application for a permit or other approval within the General Floodplain District, the Zoning Administrator must obtain, review and reasonably utilize any regional flood elevation and floodway data available from a federal, state, or other source. 2. If regional flood elevation and floodway data are not readily available, the applicant must furnish additional information, as needed, to determine the regulatory flood protection elevation and whether the proposed use would fall within the Floodway or Flood Fringe District. Information must be consistent with accepted hydrological and hydraulic engineering standards and the standards in 14- 1 -9B(3) below. 3. The determination of floodway and flood fringe must include the following components, as applicable: (a) Estimate the peak discharge of the regional (1% chance) flood. (b) Calculate the water surface profile of the regional flood based upon a hydraulic analysis of the stream channel and overbank areas. (c) Compute the floodway necessary to convey or store the regional flood without increasing flood stages more than one -half (0.5) foot. A lesser stage increase than 0.5 foot is required if, as a result of the stage increase, increased flood damages would result. An equal degree of encroachment on both sides of the stream within the reach must be assumed in computing floodway boundaries. 4. The Zoning Administrator will review the submitted information and assess the technical evaluation and the recommended Floodway and/or Flood Fringe District boundary. The assessment must include the cumulative effects of previous floodway encroachments. The Zoning Administrator may seek technical assistance from a designated engineer or other expert person or agency, including the Department of Natural Resources. Based on this assessment, the Zoning Administrator may approve or deny the application. 5. Once the Floodway and Flood Fringe District boundaries have been determined, the Zoning Administrator must process the permit application consistent with the applicable provisions of Section 14 -1 -7 and 14 -1 -8 of this ordinance. October 2015 14 -1 -10 LAND DEVELOPMENT STANDARDS A. In General: Recognizing that flood prone areas may exist outside of the designated floodplain districts, the requirements of this section apply to all land within the City of Andover. B. Subdivisions: No land may be subdivided which is unsuitable for reasons of flooding or inadequate drainage, water supply or sewage treatment facilities.
