535.1400. - Statutory authorization.

The legislature of the State of Minnesota has, in Minn. Statutes, Chapter 103F and Chapter 462 delegated the responsibility to local government units to adopt regulations designed to minimize flood losses.

535.1410. - Purpose.

(a) Regulation of development. This ordinance regulates development in the flood hazard areas of the City of Minneapolis. 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.

(c)

Preservation of natural features. This ordinance is also intended to preserve the natural characteristics and functions of watercourses and floodplains in order to moderate flood and stormwater impacts, improve water quality, reduce soil erosion, protect aquatic and riparian habitat, provide recreational opportunities, provide aesthetic benefits and enhance community and economic development.

535.1420. - General provisions.

(a) How to use this ordinance. This ordinance adopts the floodplain maps applicable to the City of Minneapolis and includes two (2) floodplain districts: Floodway and Flood Fringe.

Where Floodway and Flood Fringe Districts are delineated on the floodplain maps, the standards in section 535.1470 or 535.1480 will apply, depending on the location of a property.

(b)

Lands to which ordinance applies. This ordinance applies to all lands within the jurisdiction of the City of Minneapolis shown on the official zoning map and/or the attachments to the map as being located within the boundaries of the Floodway or Flood Fringe District.

The Floodway and Flood Fringe Districts are overlay districts that are superimposed on all existing zoning districts. The standards imposed in the overlay districts are 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 Insurance Study for Hennepin County, Minnesota, and Incorporated Areas, dated November 4, 2016 and the flood insurance rate map panels enumerated here within, dated November 4, 2016, all prepared by the Federal Emergency Management Agency. These materials are on file in the office of the zoning administrator. The effective flood insurance rate map panels are: 27053C0212F, 27053C0214F, 27053C0216F, 27053C0217F, 27053C0218F, 27053C0219F, 27053C0352F, 27053C0354F, 27053C0356F, 27053C0357F, 27053C0362F, 27053C0364F, 27053C0366F, 27053C0367F, 27053C0368F, 27053C0369F, 27053C0376F, 27053C0378F, 27053C0379F, 27053C0386F, 27053C0387F, 27053C0388F, 27053C0389F.

(d)

Interpretation. The boundaries of the zoning districts are determined by scaling distances on the flood insurance rate map. 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 shall 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.

(e)

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.

(f)

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 Minneapolis or its officers or employees for any flood damages that result from reliance on this ordinance or any administrative decision lawfully made hereunder.

(g)

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.

535.1430. - 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.

Base flood elevation. The elevation of the "regional flood." The term "base flood elevation" is used in the flood insurance survey.

Basement. Any area of a structure, including crawl spaces, having its floor or base subgrade (below ground level) on all four (4) sides, regardless of the depth of excavation below ground level.

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 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. The portion of the special flood hazard area (one (1) percent annual chance flood) located outside of the floodway. Flood fringe is synonymous with the term "floodway fringe" used in the flood insurance study for Hennepin County, Minnesota.

Flood insurance rate map (FIRM). 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).

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.

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 Code of Federal Regulations, Part 60.3.

Manufactured home. A structure, transportable in one (1) 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."

New construction. Structures, including additions and improvements, and placement of manufactured homes, for which the start of construction commenced on or after the effective date of this ordinance.

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 (100) year floodplain. Lands inundated by the "regional flood" (see definition).

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 (2) consecutive bridge crossings would most typically constitute a reach.

Recreational vehicle. A vehicle that is built on a single chassis, is four hundred (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 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 one (1) percent chance or one hundred (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 (1) 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. In Zone AO, the RFPE is established by adding one (1) foot to the highest adjacent grade to a structure's proposed location on the ground.

Repetitive loss. Flood related damages sustained by a structure on two (2) 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 twenty-five (25) percent of the market value of the structure before the damage occurred.

Special flood hazard area. A term used for flood insurance purposes synonymous with "one hundred (100) year floodplain."

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, fences, manufactured homes, recreational vehicles not meeting the exemption criteria specified in section 535.1510(b) of this ordinance 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 fifty (50) percent of the market value of the structure before the damage occurred.

Substantial improvement. Within any consecutive three hundred sixty-five-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 fifty (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, Part 59.1.

535.1440. - Administration.

An application for a variance to the provisions of this ordinance or for a conditional use permit will be processed and reviewed in accordance with applicable state statutes and Chapter 525, Administration and Procedures, and shall be subject to the additional provisions of this section.

(b)

Variances.

(1)

Adherence to state floodplain management standards. A variance shall not allow a use that is not allowed 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.

(2)

Additional variance criteria. 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 may only be issued by a community upon:

1.

A showing of good and sufficient cause;

2.

A determination that failure to grant the variance would result in exceptional hardship to the applicant; and

3.

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

(3)

The zoning administrator shall notify the applicant for a variance that:

a.

The issuance of a variance to construct a structure below the base flood level will result in increased premium rates for flood insurance up to amounts as high as twenty-five dollars ($25.00) for one hundred dollars ($100.00) of insurance coverage; and

b.

Such construction below the base or regional flood level increases risks to life and property.

(b)

Policy. The Legislature of Minnesota has delegated responsibility to local governments of the state to regulate the subdivision, use and development of designated critical areas and thus preserve and enhance the quality of important historic, cultural, aesthetic values, and natural systems and provide for the wise use of these areas.

(c)

Purpose. The Mississippi River Corridor Critical Area regulations are intended to:

(1)

Establish districts under which building height and structure placement are regulated to protect and enhance the Mississippi River's resources and features consistent with the natural and built character of each district.

(2)

Identify development standards and considerations for land uses that have potential to negatively impact primary conservation areas and public river corridor views.

(3)

Establish standards that protect primary conservation areas and public river corridor views from development impacts and ensure that new development is sited consistent with the purpose of the MRCCA.

(4)

Establish design standards for private facilities that are consistent with best management practices and that minimize impacts to primary conservation areas, public river corridor views and other resources identified in the MRCCA Plan.

(5)

Establish design standards for public facilities that are consistent with best management practices and that minimize impacts to primary conservation areas, public river corridor views and other resources identified in the MRCCA Plan while recognizing that they serve the public interest by providing access to the Mississippi River corridor or require locations within the river corridor and therefor require some flexibility.

(6)

Establish standards that sustain and enhance the biological and ecological functions of vegetation; preserve the natural character and topography of the MRCCA; and maintain stability of bluffs and critical area steep slopes and ensure stability of other erosion-prone areas.

(7)

Establish standards that protect water quality from pollutant loadings of sediment, nutrients, bacteria, and other contaminants; and maintain stability of bluffs, shorelines, and other areas prone to erosion.

Storm water treatment areas or other green infrastructure may be used to meet the protected open space requirements if the vegetation provides biological and ecological functions.

(6)

Land dedicated under Title 22 Article V for public river access, parks, or other open space or public facilities may be counted toward the protected open space requirement.

(7)

Protected open space areas must connect open space, natural areas, and recreational areas, where present on adjacent parcels, as much as possible to form an interconnected network.

(d)

Permanent protection of designated open space.

(1)

Designated open space areas must be protected through one (1) or more of the following methods:

a.

Public acquisition by a government entity for conservation purposes;

b.

A permanent conservation easement, as provided in Minn. Statutes, Chapter 84C;

c.

A deed restriction; and

d.

Other arrangements that achieve an equivalent degree of protection.

(2)

Permanent protection methods must ensure the long-term management of vegetation to meet its biological and ecological functions, prohibit structures, and prohibit land alteration, except as needed to provide public recreational facilities and access to the river.

(e)

Alternative design standards. Alterative design standards may be considered through a planned unit development or cluster development. Individual lots in a planned unit development or cluster development are not required to meet the design standards of this section if it can be demonstrated that the overall development is in compliance with the standards and purpose of this section.
