(a)

Statutory authorization. The legislature of the State of Minnesota has, in M.S.A. chs. 103F and 462, delegated the responsibility to local government units to adopt regulations designed to minimize flood losses. Therefore, the city council of City of Watertown, Minnesota, does ordain as follows:

(b)

Findings of fact.

(1)

The flood hazard areas of Watertown, Minnesota, are subject to periodic inundation which results in potential loss of life, loss of property, health and safety hazards, disruption of commerce and governmental services, extraordinary public expenditures or flood protection and relief, and impairment of the tax base, all of which adversely affect the public health, safety, and general welfare.

(2)

Methods used to analyze flood hazards. This article is based upon a reasonable method of analyzing flood hazards which is consistent with the standards established by the Minnesota Department of Natural Resources.

(3)

National Flood Insurance Program compliance. This article 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.

(c)

Statement of purpose. It is the purpose of this article to promote the public health, safety, and general welfare and to minimize those losses described in subsection 62-651(b)(1) by provisions contained herein.

(Ord. No. 345, § 1, 10-27-09; Ord. No. 409, § 1, 11-13-18)

(a)

Lands to which article applies. This article shall apply to all lands within the jurisdiction of the City of Watertown shown on the official zoning map and/or the attachments thereto as being located within the boundaries of the floodway, flood fringe, or general floodplain districts.

(b)

Establishment of official zoning map. 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 article. The attached material includes the flood insurance study for Carver County, Minnesota, and incorporated areas, dated December 21, 2018, the flood insurance rate map panels enumerated below, dated December 21, 2018, and the letter of map revision, Case No. 19-05-1618P, with an effective date of March 6, 2020, including all attached maps, tables, and flood profiles; all prepared by the Federal Emergency Management Agency. The official zoning map shall be on file in the office of the city clerk-treasurer and the zoning officer.

(c)

Regulatory flood protection elevation. The regulatory flood protection elevation shall be an elevation no lower than two feet 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.

(d)

Interpretation.

(1)

In their interpretation and application, the provisions of this article shall be held to be minimum requirements and shall be liberally construed in favor of the governing body and shall not be deemed a limitation or repeal of any other powers granted by state statutes.

(2)

The boundaries of the zoning districts shall be determined by scaling distances on the official zoning map. Where interpretation is needed as to the exact location of the boundaries of the district 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 and there is a formal appeal of the decision of the zoning administrator, the board of adjustment shall make the necessary interpretation. All decisions will be based on elevations on the regional (100-year) flood profile, the ground elevations that existed on the site at the time the community adopted its initial floodplain ordinance or on the date of the first National Flood Insurance Program map showing the area within the 100-year floodplain if earlier, and other available technical data. Persons contesting the location of the district boundaries shall be given a reasonable opportunity to present their case to the board of adjustment and to submit technical evidence.

(e)

Abrogation and greater restrictions. It is not intended by this article to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions. However, where this article imposes greater restrictions, the provisions of this article shall prevail. All other articles inconsistent with this article are hereby repealed to the extent of the inconsistency only.

(f)

Warning and disclaimer of liability. This article 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 article shall not create liability on the part of Watertown or any officer or employee thereof for any flood damages that result from reliance on this article or any administrative decision lawfully made thereunder.

(g)

Severability. If any section, clause, provision, or portion of this article is adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this article shall not be affected thereby.

(h)

Definitions. Unless specifically defined below, words or phrases used in this article shall be interpreted so as to give them the same meaning as they have in common usage and so as to give this article 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.

Basement. Any area of a structure, including crawl spaces, having its floor or base subgrade (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:

(1)

Certain conditions as detailed in the zoning ordinance exist.

(2)

The structure and/or land use conform to the comprehensive land use plan if one exists and are compatible with the existing neighborhood.

Development. Any manmade 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.

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 Watertown, Minnesota.

Flood insurance rate map. An official map on which the federal insurance administrator has delineated both the special hazard areas and the risk premium zones applicable to the community. A FIRM that has been made available digitally is called a digital flood insurance rate map (DFIRM).

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.

Flood prone area. Any land susceptible to being inundated by water from any source.

Floodproofing. 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; provided, that such enclosure is not built so as to render the structure in violation of the applicable non-elevation design requirements of 44 CFR, part 60.3.

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.

Principal use or structure. All uses or structures that are not accessory uses or structures.

Reach. A hydraulic engineering term to describe a longitudinal segment of a stream or river influenced by a natural or manmade 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 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 article, the term recreational vehicle shall be 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 100-year recurrence interval. Regional flood is synonymous with the term "base flood" used in a flood insurance study.

Regulatory flood protection elevation. The regulatory flood protection elevation shall be an elevation no lower than two feet 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 percent of the market value of the structure before the damage occurred.

Start of construction. Includes substantial improvement, and means the actual start of construction, repair, reconstruction, rehabilitation, addition, placement or other improvement that occurred before the permit's expiration date. The actual start is 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 a basement, footings, piers, 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. For a substantial improvement, the actual start of construction means the first alteration of any wall, ceiling, floor, or other structural part of a building, whether or not that alteration affects the external dimensions of the building.

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 subsection 62-659(c)(1) of this article and other similar items.

Substantial damage. 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:

(1)

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.

(2)

Any alteration of an "historic structure," provided that the alteration will not preclude the structure's continued designation as an "historic structure." For the purpose of this article, "historic structure" shall be as defined in 44 Code of Federal Regulations, Part 59.1.

Variance. A modification of a specific permitted development standard required in an official control including this article to allow an alternative development standard not stated as acceptable in the official control, but only as applied to a particular property for the purpose of alleviating a hardship, practical difficulty or unique circumstance as defined and elaborated upon in a community's respective planning and zoning enabling legislation.

(i)

Annexations. The flood insurance rate map panels adopted by reference into subsection 62-652(b) above may include floodplain areas that lie outside of the corporate boundaries of the City of Watertown at the time of adoption of this article. If any of these floodplain land areas are annexed into the City of Watertown after the date of adoption of this article, the newly annexed floodplain lands shall be subject to the provisions of this article immediately upon the date of annexation into the Watertown.

(Ord. No. 345, § 1, 10-27-09; Ord. No. 409, § 1, 11-13-18; Ord. No. 420, § 1, 3-10-20)

Floodway district. The floodway district includes those areas within zones AE delineated within floodway areas as shown on the flood insurance rate maps adopted in subsection 62-652(b). For lakes, wetlands and other basins, the floodway district also includes those areas that are at or below the ordinary high water level as defined in M.S.A. § 103G.005, Subd. 14.

(2)

Flood fringe district. The flood fringe district includes areas within zones AE on the flood insurance rate map adopted in subsection 62-652(b), but located outside of the floodway. For lakes, wetlands and other basins, the flood fringe district also includes areas mapped in zones A, which are below the one percent annual chance (100-year) flood elevation but above the ordinary high water level as defined in M.S.A. § 103G.005, Subd. 14.

(b)

Compliance. No new structure or land shall hereafter be used and no structure shall be constructed, located, extended, converted, or structurally altered without full compliance with the terms of this article and other applicable regulations which apply to uses within the jurisdiction of this article. Within the floodway, flood fringe and general floodplain districts, all uses not listed as permitted uses or conditional uses in sections 62-654, 62-655, and 62-656 that follow, respectively, shall be prohibited. In addition, a caution is provided here that:

(1)

New manufactured homes, replacement manufactured homes and certain travel trailers and travel vehicles are subject to the general provisions of this article and specifically section 62-659.

(2)

Modifications, additions, structural alterations, normal maintenance and repair, or repair after damage to existing nonconforming structures and nonconforming uses of structures or land are regulated by the general provisions of this article and specifically section 62-661.

(3)

As-built elevations for elevated or floodproofed structures must be certified by ground surveys and floodproofing techniques must be designed and certified by a registered professional engineer or architect as specified in the general provisions of this article and specifically as stated in section 62-660 of this article.

(8)

Structural works for flood control such as levees, dikes and floodwalls constructed to any height where the intent is to protect individual structures and levees or dikes where the intent is to protect agricultural crops for a frequency flood event equal to or less than the ten-year frequency flood event.

(d)

Standards for floodway conditional uses.

(1)

All uses. No structure (temporary or permanent), fill (including fill for roads and levees), deposit, obstruction, storage of materials or equipment, or other uses may be allowed as a conditional use that will cause any increase in the stage of the 100-year or regional flood or cause an increase in flood damages in the reach or reaches affected.

(2)

All floodway conditional uses shall be subject to the procedures and standards contained in subsection 62-660(d) of this article.

(3)

The conditional use shall be permissible in the underlying zoning district if one exists.

(4)

Fill:

a.

Fill, dredge spoil, and all other similar materials deposited or stored in the floodplain shall be protected from erosion by vegetative cover, mulching, riprap or other acceptable method.

b.

Dredge spoil sites and sand and gravel operations shall not be allowed in the floodway unless a long-term site development plan is submitted which includes an erosion/sedimentation prevention element to the plan.

c.

As an alternative, and consistent with subsection (b) immediately above, dredge spoil disposal and sand and gravel operations may allow temporary, on-site storage of fill or other materials which would have caused an increase to the stage of the 100-year or regional flood but only after the governing body has received an appropriate plan which assures the removal of the materials from the floodway based upon the flood warning time available. The conditional use permit must be title registered with the property in the office of the county recorder.

(5)

Accessory structures:

a.

Accessory structures shall not be designed for human habitation.

b.

Accessory structures, if permitted, shall be constructed and placed on the building site so as to offer the minimum obstruction to the flow of flood waters:

1.

Whenever possible, structures shall be constructed with the longitudinal axis parallel to the direction of flood flow; and

2.

So far as practicable, structures shall be placed approximately on the same flood flow lines as those of adjoining structures.

c.

Accessory structures shall be elevated on fill or structurally dry floodproofed in accordance with the FP-1 or FP-2 floodproofing classifications in the State Building Code. As an alternative, an accessory structure may be floodproofed to the FP-3 or FP-4 floodproofing classification in the State Building Code provided the accessory structure constitutes a minimal investment, does not exceed 500 square feet in size at its largest projection, and for a detached garage, the detached garage must be used solely for parking of vehicles and limited storage. All floodproofed accessory structures must meet the following additional standards:

1.

The structure must be adequately anchored to prevent flotation, collapse or lateral movement of the structure and shall be designed to equalize hydrostatic flood forces on exterior walls;

2.

Any mechanical and utility equipment in a structure must be elevated to or above the regulatory flood protection elevation or properly floodproofed; and

3.

To allow for the equalization of hydrostatic pressure, there must be a minimum of two "automatic" openings in the outside walls of the structure having a total net area of not less than one square inch for every square foot of enclosed area subject to flooding. 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.

(6)

Storage of materials and equipment:

a.

The storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal, or plant life is prohibited.

b.

Storage of other materials or equipment may be allowed if readily removable from the area within the time available after a flood warning and in accordance with a plan approved by the governing body.

(7)

Structural works for flood control that will change the course, current or cross section of protected wetlands or public waters shall be subject to the provisions of M.S.A., ch. 103G. Community-wide structural works for flood control intended to remove areas from the regulatory floodplain shall not be allowed in the floodway.

(8)

A levee, dike or floodwall constructed in the floodway shall not cause an increase to the 100-year or regional flood and the technical analysis must assume equal conveyance or storage loss on both sides of a stream.

(Ord. No. 345, § 1, 10-27-09)

(a)

Permitted uses. Permitted uses shall be those uses of land or structures listed as permitted uses in the underlying zoning use district(s). If no pre-existing, underlying zoning use districts exist, then any residential or nonresidential structure or use of a structure or land shall be a permitted use in the flood fringe district provided such use does not constitute a public nuisance. All permitted uses shall comply with the standards for flood fringe district "permitted uses" listed in subsection 62-655(b) and the "standards for all flood fringe uses" listed in subsection 62-655(e).

(b)

Standards for flood fringe permitted uses.

(1)

All structures, including accessory structures, must be elevated on fill so that the lowest floor including basement floor is at or above the regulatory flood protection elevation. The finished fill elevation for structures shall be no lower than one foot below the regulatory flood protection elevation and the fill shall extend at such elevation at least 15 feet beyond the outside limits of the structure erected thereon.

(2)

As an alternative to elevation on fill, accessory structures that constitute a minimal investment and that do not exceed 500 square feet at its largest projection may be internally floodproofed in accordance with subsection 62-654(d)(5)c.

(3)

The cumulative placement of fill where at any one time in excess of 500 cubic yards of fill is located on the parcel shall be allowable only as a conditional use, unless said fill is specifically intended to elevate a structure in accordance with subsection 62-655(e) of this article.

(4)

The storage of any materials or equipment shall be elevated on fill to the regulatory flood protection elevation.

(5)

The provisions of subsection 62-655(e) of this article shall apply.

(c)

Conditional uses. Any structure that is not elevated on fill or floodproofed in accordance with subsection 62-655(b)(1), (2) and or any use of land that does not comply with the standards in subsection 62-655(b)(3), (4) shall only be allowable as a conditional use. An application for a conditional use shall be subject to the standards and criteria and evaluation procedures specified in subsections 62-655(d), (e) and 62-660(d) of this article.

(d)

Standards for flood fringe conditional uses.

(1)

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 must 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.

A minimum area of openings in the walls where internal flooding is to be used as a floodproofing 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 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.

(2)

Basements, as defined by subsection 62-652(h) of this article, shall be subject to the following:

a.

Residential basement construction shall not be allowed below the regulatory flood protection elevation.

b.

Nonresidential basements may be allowed below the regulatory flood protection elevation provided the basement is structurally dry floodproofed in accordance with subsection 62-655(d)(3) of this article.

(3)

All areas of nonresidential structures including basements to be placed below the regulatory flood protection elevation shall be floodproofed in accordance with the structurally dry floodproofing classifications in the State Building Code. Structurally dry floodproofing must meet the FP-1 or FP-2 floodproofing classification in the State Building Code and this shall require making the structure watertight with the walls substantially impermeable to the passage of water and with structural components having the capability of resisting hydrostatic and hydrodynamic loads and the effects of buoyancy. Structures floodproofed to the FP-3 or FP-4 classification shall not be permitted.

(4)

When at any one time more than 500 cubic yards of fill or other similar material is located on a parcel for such activities as on-site storage, landscaping, sand and gravel operations, landfills, roads, dredge spoil disposal or construction of flood control works, an erosion/sedimentation control plan must be submitted unless the community is enforcing a state approved shoreland management ordinance. In the absence of a state approved shoreland ordinance, the plan must clearly specify methods to be used to stabilize the fill on site for a flood event at a minimum of the 100-year or regional flood event. The plan must be prepared and certified by a registered professional engineer or other qualified individual acceptable to the governing body. 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:

a.

The storage or processing of materials that are, in time of flooding, flammable, explosive, or potentially injurious to human, animal, or plant life is prohibited.

b.

Storage of other materials or equipment may be allowed if readily removable from the area within the time available after a flood warning and in accordance with a plan approved by the governing body.

(6)

The provisions of subsection 62-655(e) of this article shall also apply.

(e)

Standards for all flood fringe uses.

(1)

All new principal structures must have vehicular access at or above an elevation not more than two feet below the regulatory flood protection elevation. If a variance to this requirement is granted, the board of adjustment must specify limitations on the period of use or occupancy of the structure for times of flooding and only after determining that adequate flood warning time and local flood emergency response procedures exist.

(2)

Commercial uses. Accessory land uses, such as yards, railroad tracks, and parking lots may be at elevations lower than the regulatory flood protection elevation. However, a permit for such facilities to be used by the employees or the general public shall not be granted in the absence of a flood warning system that provides adequate time for evacuation if the area would be inundated to a depth and velocity such that when multiplying the depth (in feet) times velocity (in feet per second) the product number exceeds four upon occurrence of the regional flood.

(3)

Manufacturing and industrial uses. Measures shall be taken to minimize interference with normal plant operations especially along streams having protracted flood durations. Certain accessory land uses such as yards and parking lots may be at lower elevations subject to requirements set out in subsection 62-655(e)(2) above. In considering permit applications, due consideration shall be given to needs of an industry whose business requires that it be located in floodplain areas.

(4)

Fill shall be properly compacted and the slopes shall be properly protected by the use of riprap, vegetative cover or other acceptable method. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 100-year flood elevation FEMA's requirements incorporate specific fill compaction and side slope protection standards for multi-structure or multi-lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested.

(5)

Floodplain developments shall not adversely affect the hydraulic capacity of the channel and adjoining floodplain of any tributary watercourse or drainage system where a floodway or other encroachment limit has not been specified on the official zoning map.

(6)

Standards for recreational vehicles are contained in subsection 62-659(c).

(7)

All manufactured homes must be securely anchored to an adequately anchored foundation system that resists flotation, collapse and lateral movement. Methods of anchoring may include, but are not to be limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state or local anchoring requirements for resisting wind forces.

(Ord. No. 345, § 1, 10-27-09)

Editor's note— Ord. No. 409, § 1, adopted Nov. 13, 2018, repealed § 62-656 which pertained to the general floodplain district and derived from Ord. No. 345, § 1, adopted Oct. 27, 2009.

(a)

Review criteria. No land shall be subdivided which is unsuitable for the reason of flooding, inadequate drainage, water supply or sewage treatment facilities. All lots within the floodplain districts shall be able to contain a building site outside of the floodway district at or above the regulatory flood protection elevation. All subdivisions shall have water and sewage treatment facilities that comply with the provisions of this article and have road access both to the subdivision and to the individual building sites no lower than two feet below the regulatory flood protection elevation. For all subdivisions in the floodplain, the floodway and flood fringe district boundaries, the regulatory flood protection elevation and the required elevation of all access roads shall be clearly labeled on all required subdivision drawings and platting documents.

(b)

Floodway/flood fringe determinations in the general floodplain district. In the general floodplain district, applicants shall provide the information required in subsection 62-656(b) of this article to determine the 100-year flood elevation, the floodway and flood fringe district boundaries and the regulatory flood protection elevation for the subdivision site.

(c)

Removal of special flood hazard area designation. The Federal Emergency Management Agency (FEMA) has established criteria for removing the special flood hazard area designation for certain structures properly elevated on fill above the 100-year flood elevation. FEMA's requirements incorporate specific fill compaction and side slope protection standards for multi-structure or multi-lot developments. These standards should be investigated prior to the initiation of site preparation if a change of special flood hazard area designation will be requested.

(d)

[Delineated floodplain.] No subdivision of land shall occur which creates a lot extending into a delineated floodplain.

(Ord. No. 345, § 1, 10-27-09)

(a)

Public utilities. All public utilities and facilities such as gas, electrical, sewer, and water supply systems to be located in the floodplain shall be floodproofed in accordance with the State Building Code or elevated to above the regulatory flood protection elevation.

(b)

Public transportation facilities. Railroad tracks, roads, and bridges to be located within the floodplain shall comply with sections 62-654 and 62-655 of this article. Elevation to the regulatory flood protection elevation shall be provided where failure or interruption of these transportation facilities would result in danger to the public health or safety or where such facilities are essential to the orderly functioning of the area. Minor or auxiliary roads or railroads may be constructed at a lower elevation where failure or interruption of transportation services would not endanger the public health or safety.

(c)

On-site sewage treatment and water supply systems. Where public utilities are not provided: 1) On-site water supply systems must be designed to minimize or eliminate infiltration of flood waters into the systems; and 2) New or replacement on-site sewage treatment systems must be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters and they shall not be subject to impairment or contamination during times of flooding.

(a)

New manufactured home parks and expansions to existing manufactured home parks shall be subject to the provisions placed on subdivisions by section 62-657 of this article.

(b)

The placement of new or replacement manufactured homes in existing manufactured home parks or on individual lots of record that are located in floodplain districts will be treated as a new structure and may be placed only if elevated in compliance with section 62-655 of this article. If vehicular road access for pre-existing manufactured home parks is not provided in accordance with subsection 62-655(e)(1), then replacement manufactured homes will not be allowed until the property owner(s) develops a flood warning emergency plan acceptable to the governing body.

(1)

All manufactured homes must be securely anchored to an adequately anchored foundation system that resists flotation, collapse and lateral movement. Methods of anchoring may include, but are not to be limited to, use of over-the-top or frame ties to ground anchors. This requirement is in addition to applicable state or local anchoring requirements for resisting wind forces.

(c)

Recreational vehicles that do not meet the exemption criteria specified in subsection (c)(l) below shall be subject to the provisions of this article and as specifically spelled out in subsection (c)(3), (4) below.

(1)

Administrative review. The board of adjustment shall hear and decide appeals where it is alleged there is error in any order, requirement, decision, or determination made by an administrative official in the enforcement or administration of this article.

(3)

Variances. The board of adjustment may authorize upon appeal in specific cases such relief or variance from the terms of this article as will not be contrary to the public interest and only for those circumstances such as hardship, practical difficulties or circumstances unique to the property under consideration, as provided for in the respective enabling legislation for planning and zoning for cities or counties as appropriate. In the granting of such variance, the board of adjustment shall clearly identify in writing the specific conditions that existed consistent with the criteria specified in this article, any other zoning regulations in the community, and in the respective enabling legislation that justified the granting of the variance. No variance shall have the effect of allowing in any district uses prohibited in that district, permit a lower degree of flood protection than the regulatory flood protection elevation for the particular area, or permit standards lower than those required by state law. The following additional variance criteria of the Federal Emergency Management Agency must be satisfied:

a.

Variances shall not be issued by a community within any designated regulatory floodway if any increase in flood levels during the base flood discharge would result.

b.

Variances shall only be issued by a community upon (i) a showing of 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.

Variances shall only be issued upon a determination that the variance is the minimum necessary, considering the flood hazard, to afford relief.

(4)

Hearings. Upon filing with the board of adjustment of an appeal from a decision of the zoning officer, or an application for a variance, the board of adjustment shall fix a reasonable time for a hearing and give due notice to the parties in interest as specified by law. The board of adjustment shall submit by mail to the commissioner of natural resources a copy of the application for proposed variances sufficiently in advance so that the commissioner will receive at least ten days notice of the hearing.

(5)

Decisions. The board of adjustment shall arrive at a decision on such appeal or variance within the timeline as stated in M.S.A. § 15.19. In passing upon an appeal, the board of adjustment may, so long as such action is in conformity with the provisions of this article, reverse or affirm, wholly or in part, or modify the order, requirement, decision or determination of the zoning officer or other public official. It shall make its decision in writing setting forth the findings of fact and the reasons for its decisions. In granting a variance the board of adjustment may prescribe appropriate conditions and safeguards such as those specified in subsection 62-660(e)(6), which are in conformity with the purposes of this article. Violations of such conditions and safeguards, when made a part of the terms under which the variance is granted, shall be deemed a violation of this article punishable under section 62-662. A copy of all decisions granting variances shall be forwarded by mail to the commissioner of natural resources within 15 days of such action.

(6)

Appeals. Appeals from any decision of the board of adjustment may be made, and as specified in this community's official controls and also by Minnesota Statutes.

(7)

Flood insurance notice and record keeping. The zoning officer shall notify the applicant for a variance that: 1) the issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance and 2) such construction below the 100-year or regional flood level increases risks to life and property. Such notification shall be maintained with a record of all variance actions. A community shall maintain a record of all variance actions, including justification for their issuance, and report such variances issued in its annual or biennial report submitted to the officer of the National Flood Insurance Program.

(e)

Conditional uses. The city council shall hear and decide applications for conditional uses permissible under this article. Applications shall be submitted to the zoning administrator who shall forward the application to planning commission for consideration.

(1)

Hearings. Upon filing with the City of Watertown a complete application for a conditional use permit, the zoning administrator shall submit by mail to the commissioner of natural resources a copy of the application for proposed conditional use sufficiently in advance so that the commissioner will receive at least ten days notice of the hearing.

In all cases where a public hearing is required, a notice of the time, place and purpose of the hearing shall be published in the official newspaper of the municipality at least ten days prior to the day of the hearing. When an amendment involves changes in district boundaries affecting an area of five acres or less, a similar notice shall be mailed at least ten days before the day of the hearing to each owner of affected property and property situated wholly or partly within 350 feet of the property to which the amendment relates. For the purpose of giving mailed notice, the person responsible for mailing the notice may use any appropriate records to determine the names and addresses of owners. A copy of the notice and a list of the owners and addresses to which the notice was sent shall be attested to by the responsible person and shall be made a part of the records of the proceedings. The failure to give mailed notice to individual property owners, or defects in the notice shall not invalidate the proceedings, provided a good faith attempt was made to give property notice.

Within a reasonable period of time, the planning commission shall hold a public hearing and hear the application for the conditional use permit. The planning commission shall make its recommendation in writing to the city council. The recommendation of the planning commission shall be presented by the zoning administrator at the next regularly scheduled meeting of the city council.

(2)

Decisions. The city council shall arrive at a decision on a conditional use within the timeline as stated in M.S.A. § 15.19. In granting a conditional use permit the city council shall prescribe appropriate conditions and safeguards, in addition to those specified in subsection (e)(6), which are in conformity with the purposes of this article. Violations of such conditions and safeguards, when made a part of the terms under which the conditional use permit is granted, shall be deemed a violation of this article punishable under section 62-662. A copy of all decisions granting conditional use permits shall be forwarded by mail to the commissioner of natural resources within 15 days of such action.

(3)

Procedures to be followed by the planning commission in passing on conditional use permit applications within all floodplain districts.

a.

(1)

No such use shall be expanded, changed, enlarged, or altered in a way that increases its nonconformity.

(2)

Any structural alteration or addition to a nonconforming structure or nonconforming use which would result in increasing the flood damage potential of that structure or use shall be protected to the regulatory flood protection elevation in accordance with any of the elevation on fill or floodproofing techniques (i.e., FP-1 thru FP-4 floodproofing classifications) allowable in the State Building Code, except as further restricted in subsections (3) and (5) below.

(3)

The cost of all structural alterations or additions to any nonconforming structure over the life of the structure shall not exceed 50 percent of the market value of the structure unless the conditions of this section are satisfied. The cost of all structural alterations and additions must include all costs such as construction materials and a reasonable cost placed on all manpower or labor as estimated by the building inspector and approved by the city council. If the cost of all previous and proposed alterations and additions exceeds 50 percent of the market value of the structure, then the structure must meet the standards of subsection 62-654 or 62-655 of this article for new structures depending upon whether the structure is in the floodway or flood fringe district, respectively.

(4)

A nonconforming use or structure that has been discontinued or abandoned for a period of one year shall not be re-established and any future use shall be in conformity with the regulations of this chapter.

(5)

If any nonconforming use or structure is substantially damaged, as defined in subsection 62-652(h) of this article, it shall not be reconstructed except in conformity with the provisions of this article. The applicable provisions for establishing new uses or new structures in sections 62-654, 62-655 or 62-656 will apply depending upon whether the use or structure is in the floodway, flood fringe or general floodplain district, respectively.

(a)

Violation of the provisions of this article or failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with grants of variances or conditional uses) shall constitute a misdemeanor and shall be punishable as defined by law.

(b)

Nothing herein contained shall prevent the City of Watertown from taking such other lawful action as is necessary to prevent or remedy any violation. Such actions may include but are not limited to:

(1)

In responding to a suspected violation of this article, the zoning administrator and local government may utilize the full array of enforcement actions available to it including but not limited to prosecution and fines, injunctions, after-the-fact permits, orders for corrective measures or a request to the National Flood Insurance Program for denial of flood insurance availability to the guilty party. The community must act in good faith to enforce these official controls and to correct ordinance violations to the extent possible so as not to jeopardize its eligibility in the National Flood Insurance Program.

(2)

When an article violation is either discovered by or brought to the attention of the zoning officer, the zoning officer shall immediately investigate the situation and document the nature and extent of the violation of the official control. As soon as is reasonably possible, this information will be submitted to the appropriate department of natural resources' and Federal Emergency Management Agency Regional Office along with the community's plan of action to correct the violation to the degree possible.

(3)

The zoning officer shall notify the suspected party of the requirements of this article and all other official controls and the nature and extent of the suspected violation of these controls. If the structure and/or use is under construction or development, the zoning officer may order the construction or development immediately halted until a proper permit or approval is granted by the community. If the construction or development is already completed, then the zoning officer may either: (1) issue an order identifying the corrective actions that must be made within a specified time period to bring the use or structure into compliance with the official controls; or (2) notify the responsible party to apply for an after-the-fact permit/development approval within a specified period of time not to exceed 30 days.

(4)

If the responsible party does not appropriately respond to the zoning officer within the specified period of time, each additional day that lapses shall constitute an additional violation of this article and shall be prosecuted accordingly. The zoning officer shall also upon the lapse of the specified response period notify the landowner to restore the land to the condition which existed prior to the violation of this article.

(Ord. No. 345, § 1, 10-27-09)

The floodplain designation on the official zoning map shall not be removed from floodplain areas unless it can be shown that the designation is in error or that the area has been filled to or above the elevation of the regulatory flood protection elevation and is contiguous to lands outside the floodplain. Special exceptions to this rule may be permitted by the commissioner of natural resources if he determines that, through other measures, lands are adequately protected for the intended use.

All amendments to this article, including amendments to the official zoning map, must be submitted to and approved by the commissioner of natural resources prior to adoption. Changes in the official zoning map must meet the Federal Emergency Management Agency's (FEMA) Technical Conditions and Criteria and must receive prior FEMA approval before adoption.
