This chapter is adopted pursuant to the authorization in §§ 62.23, 62.231, 87.30 and 281.31, Wis. Stats.
Uncontrolled use of the shoreland-wetlands and pollution of the navigable waters of the municipality would adversely affect the public health, safety, convenience, and general welfare and impair the tax base. The Legislature of Wisconsin has delegated responsibility to all municipalities to:
A. 
Promote the public health, safety, convenience and general welfare;
B. 
Maintain the stormwater and floodwater storage capacity of wetlands;
C. 
Prevent and control water pollution by preserving wetlands which filter or store sediments, nutrients, heavy metals or organic compounds that would otherwise drain into navigable waters;
D. 
Protect fish, their spawning grounds, other aquatic life and wildlife by preserving wetlands and other aquatic habitat;
E. 
Prohibit certain uses detrimental to the shoreland-wetland area; and
F. 
Preserve shore cover and natural beauty by restricting the removal of natural shoreland cover and controlling shoreland-wetland excavation, filling and other earthmoving activities.
The use of wetlands and the alteration of wetlands within the shoreland area of the municipality shall be in full compliance with the terms of this chapter and other applicable local, state or federal regulations. (However, see § 420-12 of this chapter for the standards applicable to nonconforming uses.) All permitted development shall require the issuance of a zoning permit unless otherwise expressly excluded by a provision of this chapter.
Unless specifically exempted by law, all cities, villages, towns, and counties are required to comply with this chapter and obtain all necessary permits. State agencies are required to comply if § 13.48(13), Wis. Stats., applies. The construction, reconstruction, maintenance and repair of state highways and bridges by the Wisconsin Department of Transportation are exempt when § 30.2022, Wis. Stats., applies.
A. 
This chapter supersedes all the provisions of any municipal zoning ordinance enacted under § 62.23 or 87.30, Wis. Stats., which relate to floodplains and shoreland-wetlands, except that where another municipal zoning ordinance is more restrictive than this chapter, that ordinance shall continue in full force and effect to the extent of the greater restrictions, but not otherwise.
B. 
This chapter is not intended to repeal, abrogate or impair any existing deed restrictions, covenants or easements. However, where this chapter imposes greater restrictions, the provisions of this chapter shall prevail.
In their interpretation and application, the provisions of this chapter shall be held to be minimum requirements and shall be liberally construed in favor of the municipality and shall not be deemed a limitation or repeal of any other powers granted by the Wisconsin Statutes. Where a provision of this chapter is required by a standard in Ch. NR 117, Wis. Adm. Code, and where the provision of this chapter is unclear, the provision shall be interpreted in light of the Ch. NR 117 standards in effect on the date of the adoption of this chapter or in effect on the date of the most recent text amendment to this chapter.
The county shoreland zoning provisions in effect on the date of annexation remain in effect and shall be administered by the municipality for all areas annexed by the municipality after May 7, 1982, unless any of the changes as allowed by § 59.692(7)(a)1 to 3, Wis. Stats., occurs. These annexed lands are described on the municipality's Official Zoning Map. The county shoreland zoning provisions are incorporated by reference for the purpose of administering this section and are on file in the office of the Zoning Administrator.

A. 
The shoreland-wetland zoning district includes all wetlands in the municipality which are five acres or more and are shown on the Final Wetland Inventory Map that has been adopted and made a part of this chapter and which are:
(1) 
Within 1,000 feet of the ordinary high-water mark of navigable lakes, ponds or flowages. Lakes, ponds or flowages in the municipality shall be presumed to be navigable if they are shown on the United States Geological Survey quadrangle maps or other zoning base maps which have been incorporated by reference and made a part of this chapter.
(2) 
Within 300 feet of the ordinary high-water mark of navigable rivers or streams, or to the landward side of the floodplain, whichever distance is greater. Rivers and streams shall be presumed to be navigable if they are designated as either continuous or intermittent waterways on the United States Geological Survey quadrangle maps or other zoning base maps which have been incorporated by reference and made a part of this chapter. Floodplain zoning maps adopted in § 420-8 shall be used to determine the extent of floodplain areas.
B. 
Determinations of navigability and ordinary high-water mark location shall initially be made by the Zoning Administrator. When questions arise, the Zoning Administrator shall contact the appropriate district office of the Department for a final determination of navigability or ordinary high-water mark.
C. 
When an apparent discrepancy exists between the shoreland-wetland district boundary shown on the official zoning maps and actual field conditions at the time the maps were adopted, the Zoning Administrator shall contact the appropriate district office of the Department to determine if the shoreland-wetland district boundary, as mapped, is in error. If Department staff concur with the Zoning Administrator that a particular area was incorrectly mapped as a wetland, the Zoning Administrator shall have the authority to immediately grant or deny a zoning permit in accordance with the regulations applicable to the correct zoning district. In order to correct wetland mapping errors or acknowledge exempted wetlands designated in Subsections D and E, the Zoning Administrator shall be responsible for initiating a map amendment within a reasonable period.
D. 
Filled wetlands. Wetlands which are filled prior to the date on which the municipality received final wetland inventory maps, in a manner which affects their wetland characteristics to the extent that the area can no longer be defined as wetland, are not subject to this chapter.
E. 
Wetlands landward of a bulkhead line. Wetlands located between the original ordinary high-water mark and a bulkhead line established prior to May 7, 1982, under § 30.11, Wis. Stats., are not subject to this chapter.

WETLAND ALTERATION
Any filling, flooding, draining, dredging, ditching, tiling, excavating, temporary water level stabilization measures or dike and dam construction in a wetland area.
WETLANDS
Those areas where water is at, near or above the land surface long enough to support aquatic or hydrophytic vegetation and which have soils indicative of wet conditions.
