For the purposes of this chapter, the following definitions shall apply unless the context clearly indicates or requires a different meaning.

   DEVELOPMENT. Any man-made change to real estate, including but not limited to construction or reconstruction of buildings, installing manufactured homes or travel trailers, installing utilities, construction of roads or bridges, erection of levees, walls, or fences, drilling, mining, filling, dredging, and storage of materials.

   FLOOD. A general and temporary condition of partial or complete inundation of normally dry land areas from overflow of inland or tidal waves, or the unusual and rapid accumulation or runoff of surface waters from any source.

   FLOODPLAIN or FLOOD PRONE AREA. Any land area susceptible to being inundated by water from any source.

   FLOODPROOFING. Any combination of structural and non-structural additions, changes or adjustments to structures which reduce or eliminate flood damage to real estate or improved real property, water and sanitary facilities, structures and their contents.

   MANUFACTURED HOME. A structure, transportable in one or more sections, which is built on a permanent chassis and is designated for use with or without a permanent foundation when attached to the required utilities.

   NEW CONSTRUCTION. For the purposes of determining insurance rates, structures for which the "start of construction" commenced on or after the effective date of an initial FIRM or after December 31, 1974, whichever is later, and includes any subsequent improvements to such structures. For floodplain management purposes, NEW CONSTRUCTION means structures for which the start of construction commenced on or after the effective date of a floodplain management regulation adopted by a community and includes any subsequent improvements to such structures.

   PERSON. Any individuals, corporation, partnership, association, or any other entity, including state and local governments and agencies.

   SPECIAL FLOOD HAZARD AREA. The land in the floodplain within a community subject to a 1% or greater chance of flooding in any given year. The area may be designated as Zone A on the FHBM. After detailed ratemaking has been completed in preparation for publication of the flood insurance rate map, Zone A usually is refined into Zones A, AO, AH, A1-30, AE, A99, AR, AR/A1-30, AR/AE, AR/AO, AR/AH, AR/A, VO, or V1-30, VE, or V. For purposes of these regulations, the term SPECIAL FLOOD HAZARD AREA is synonymous in meaning with the phrase "area of special flood hazard."

   STRUCTURE. For floodplain management purposes, a walled and roofed building, including gas or liquid storage tanks, that is principally above ground. The term includes recreational vehicles and travel trailers on site for more than 180 days.

   SUBSTANTIAL IMPROVEMENT. Any repair, reconstruction or improvement of a structure, the cost of which equals or exceeds 50% of the market value of the structure either, (a) before the improvement or repair is started, or (b) if the structure has been damaged, and is being restored, before the damage occurred. For the purposes of this definition, SUBSTANTIAL IMPROVEMENT is considered to occur when the first alteration of any wall, ceiling, floor, or other structural part of the building commences, whether or not that alteration affects the external dimensions of the structure regardless of the actual work performed. The term does not, however, include either (1) any project for improvement of a structure to comply with existing state or local health, sanitary, or safety code specifications which are solely necessary to assure safe living conditions or (2) any alteration of a "historic structure," provided that the alteration will not preclude the structure's continued designation as a historic structure.

(Ord. 2004-2, passed 7-26-2004)

   (A)   No person shall erect, construct, enlarge, alter, repair, improve, move, or demolish any building or structure without first obtaining a separate permit for each building or structure from the designated responsible person.

   (B)   No man-made change to improved or unimproved real estate, including but not limited to buildings or other structures, fences, mining, dredging, filling, grading, paving, excavation or drilling operations, shall be commenced until a separate permit has been obtained from the designated responsible person for each change.

   (C)   No manufactured home shall be placed on improved or unimproved real estate without first obtaining a separate permit for each mobile home from the designated responsible person.

(Ord. 2004-2, passed 7-26-2004)

   To obtain a permit, the applicant shall first file a permit application on a form furnished for that purpose. The form must be completed and submitted to the designated responsible person before the issuance of a permit will be considered.

(Ord. 2004-2, passed 7-26-2004)

   (A)   The Administrator-Clerk-Treasurer, hereinafter referred to as the responsible person, is appointed as the "person" responsible for receiving applications and examining the plans and specifications for the proposed construction or development.

   (B)   After reviewing the application, the responsible person may require any additional measures which are necessary to meet the minimum requirements of this chapter.

   (C)   The responsible person shall review proposed development to assure that all necessary permits have been received from those governmental agencies from which approval is required by federal or state law, including § 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. § 1334.

(Ord. 2004-2, passed 7-26-2004)

   The responsible person shall review all permit applications to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is in a flood prone area, all new construction and substantial improvements (including the placement of manufactured homes) shall be:

   (A)   Designed (or modified) and adequately anchored to prevent floatation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;

   (B)   Constructed with materials and utility equipment resistant to flood damage;

   (C)   Constructed by methods and practices that minimize flood damage; and

   (D)   Constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

(Ord. 2004-2, passed 7-26-2004)

   The responsible person shall review subdivision proposals and other proposed new development to determine whether such proposals will be reasonably safe from flooding. If a subdivision proposal or other proposed new development is in a flood prone area, any such proposal shall be reviewed to assure that:

   (A)   All such proposals are consistent with the need to minimize flood damage within the flood prone area;

   (B)   All public utilities and facilities, such as sewer, gas, electrical, and water systems are located and constructed to minimize or eliminate flood damage; and

   (C)   Adequate drainage is provided to reduce exposure of flood hazard.

(Ord. 2004-2, passed 7-26-2004)

   The responsible person shall require within flood prone areas, new and replacement water supply systems to be designed to minimize or eliminate infiltration of flood waters into the systems.

(Ord. 2004-2, passed 7-26-2004)

   The responsible person shall require within flood prone areas:

   (A)   New and replacement sanitary sewage systems to be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters; and

(Ord. 2004-2, passed 7-26-2004)

   The city shall not approve any development located in a Special Flood Hazard Area (SFHA) outside the corporate limits unless such development or plat is in accordance with the following:

   (B)   The SFHA's of those parts of unincorporated Hennepin County, Minnesota, that are within the extraterritorial jurisdiction of the city or that may be annexed into the city are generally identified as such on the Flood Hazard Boundary Map (FHBM) dated September 2, 2004, or the Flood Insurance Rate Map (FIRM) dated September 2, 2004, prepared by the Federal Emergency Management Agency (FEMA) or the Department of Housing and Urban Development (HUD).
