The provisions of this article apply to all areas within the Flood-Fringe District, as shown on the Official Floodplain Zoning Maps, and to those portions of the General Floodplain District that are determined to be in the flood-fringe area pursuant to § 143-19.
Any structures, land use, or development, including accessory structures and uses, are allowed within the Flood-Fringe District and flood-fringe portions of the General Floodplain District, provided that the standards contained in § 143-15 are met, that the use is not prohibited by this or any other ordinance or any other local, state or federal regulation and that all permits or certificates specified in § 143-24 have been issued.
A. 
All of the provisions of § 143-6 shall apply in addition to the following requirements according to the use requested.
B. 
Residential uses. Any structure or building used for human habitation, including a manufactured home, which is to be erected, constructed, reconstructed, altered, or moved into the flood-fringe area, shall meet or exceed the following standards:
(1) 
The elevation of the lowest floor, excluding the basement or crawlway, shall be at or above the flood protection elevation (which is a point two feet above the regional flood elevation) on fill except where Subsection B(2) is applicable. The fill elevation shall be one foot or more above the regional flood elevation extending at least 15 feet beyond the limits of the structure. The Department may authorize other floodproofing measures where existing streets or sewer lines are at elevations which make compliance impractical, provided that the Zoning Board of Appeals grants a variance due to dimensional restrictions.
(2) 
The basement or crawlway floor may be placed at the regional flood elevation, provided that it is floodproofed to the flood protection elevation. No basement or crawlway floor is allowed below the regional flood elevation.
(3) 
Contiguous dry land access, defined in § 143-34 as a vehicle access route above regional flood elevation, shall be provided from a structure or building to land which is outside of the floodplain, except as provided in Subsection B(4).
(4) 
In existing developments where existing sheets or sewer lines are at elevations which make compliance with Subsection B(3) impractical, the municipality may permit new development and substantial improvements where access roads are at or below the regional flood elevation, provided that:
(a) 
The municipality has written assurance from the appropriate local units of police, fire and emergency services that rescue and relief will be provided to the structure(s) by wheeled vehicles, considering the anticipated depth, duration and velocity of the regional flood event; or
(b) 
The municipality has an adequate natural disaster plan concurred with by the Division of Emergency Management and approved by the Department.
C. 
Accessory structures or uses.
(1) 
Except as provided in Subsection C(2), an accessory structure which is not connected to a principal structure may be constructed with its lowest floor at or above the regional flood elevation.
(2) 
An accessory structure which is not connected to the principal structure and which is less than 600 feet in size and valued at less than $10,000 may be constructed with its lowest floor no more than two feet below the regional flood elevation if it is subject to flood velocities of no more than two feet per second and it meets all of the provisions of § 143-11B and Subsection F below.
D. 
Commercial uses. Any commercial structure or building which is to be erected, constructed, reconstructed, altered or moved into the flood-fringe area shall meet the requirements of § 143-15B. Storage yards, parking lots and other accessory structures or land uses may be at lower elevations, subject to the requirements of Subsection F. However, no such area in general use by the public shall be inundated to a depth greater than two feet or subjected to flood velocities greater than two feet per second during the regional flood. Inundation of such yards or parking areas exceeding two feet may be allowed, provided that an adequate warning system exists to protect life and property.
E. 
Manufacturing and industrial uses. Any manufacturing or industrial structure or building which is to be erected, constructed, reconstructed, altered or moved into the flood-fringe area shall be protected to the flood protection elevation utilizing fill, levees, floodwalls, adequate floodproofing measures in accordance with § 143-28, or any combination thereof. On streams or rivers having prolonged flood durations, greater protection may be required to minimize interference with normal plant operations. A lesser degree of protection, compatible with the criteria in Subsections D and F may be permissible for storage yards, parking lots and other accessory structures or uses.
F. 
Storage materials. The storage of materials that are buoyant, flammable, or explosive or which, in times of flooding, could be injurious to property, water quality or human, animal, plant, fish or aquatic life shall be at or above the flood protection elevation for the particular area or floodproofed in compliance with § 143-28. Adequate measures shall be taken to assure that said materials will not enter the river or stream during flooding.
G. 
Public utilities, streets and bridges. All utilities, streets and bridges should be designed to be compatible with the local comprehensive floodplain development plans; and
(1) 
When failure or interruption of public utilities, streets and bridges would result in danger to the public health or safety or where such facilities are essential to the orderly functioning of the area, construction of and substantial improvements to such facilities may only be permitted if they are floodproofed, in compliance with § 143-28, to the flood protection elevation;
(2) 
Minor or auxiliary roads or nonessential utilities may be constructed at lower elevations, provided that they withstand flood forces to the regional flood elevation.
H. 
Sewage systems. All on-site sewage disposal systems shall be floodproofed to the flood protection elevation and shall meet the applicable provisions of all local ordinances and Ch. Comm 83, Wis. Adm. Code.
I. 
Wells. All public or private wells shall be floodproofed to the flood protection elevation, pursuant to § 143-28, and shall meet the applicable provisions of Chs. NR 811 and NR 812, Wis. Adm. Code.
J. 
Solid waste disposal sites. All public or private solid or hazardous waste disposal sites are prohibited in flood-fringe areas.
K. 
Deposition of materials. Any materials deposited for any purpose may only be allowed if all the provisions of this chapter are met.
L. 
Manufactured homes.
(1) 
Owners or operators of all manufactured home parks and subdivisions shall provide adequate surface drainage to minimize flood damage and prepare, secure approval and file an evacuation plan, indicating vehicular access and escape routes, with local emergency management authorities.
(2) 
In existing manufactured home parks, all new homes, replacement homes on existing pads, and substantially improved homes shall:
(a) 
Have the lowest floor elevated to the flood protection elevation; and
(b) 
Be anchored so they do not float, collapse or move laterally during a flood.
(3) 
Outside of existing manufactured home parks, including new manufactured home parks and all single units outside of existing parks, all new, replacement and substantially improved manufactured homes shall meet the residential development standards for the flood-fringe in § 143-15B.

Mobile recreational vehicles. All mobile recreational vehicles that are on site for 180 consecutive days or more or are not fully licensed and ready for highway use shall meet the elevation and anchoring requirements in Subsection L(2) and (3). A mobile recreational vehicle is ready for highway use if it is on its wheel or jacking system, is attached to the site only by quick-disconnect utilities and security devices and has no permanently attached additions.
