Chapter NR 115
WISCONSIN’S SHORELAND PROTECTION PROGRAM
NR 115.04 Shoreland-wetlands. NR 115.05 Minimum zoning standards for shorelands. NR 115.06 Department duties. Ch. NR 115 NoteNote: Chapter NR 115 as it existed on July 31, 1980, was repealed and a new chapter NR 115 was created effective August 1, 1980.
NR 115.01NR 115.01 Purpose. Section 281.31, Stats., provides that shoreland subdivision and zoning regulations shall: “further the maintenance of safe and healthful conditions; prevent and control water pollution; protect spawning grounds, fish and aquatic life; control building sites, placement of structure and land uses and reserve shore cover and natural beauty.” Section 59.692, Stats., requires counties to effect the purposes of s. 281.31, Stats., and to promote the public health, safety and general welfare by adopting zoning regulations for the protection of all shorelands in unincorporated areas that meet shoreland zoning standards promulgated by the department. The purpose of this chapter is to establish minimum shoreland zoning standards for ordinances enacted under s. 59.692, Stats., for the purposes specified in s. 281.31 (1), Stats., and to limit the direct and cumulative impacts of shoreland development on water quality; near-shore aquatic, wetland and upland wildlife habitat; and natural scenic beauty. Nothing in this rule shall be construed to limit the authority of a county to enact more restrictive shoreland zoning standards under s. 59.69 or 59.692, Stats., to effect the purposes of s. 281.31, Stats. NR 115.01 NoteNote: Effective April 17, 2012, 2011 Wisconsin Act 170 created s. 59.692 (2m), Stats., which prohibits a county from enacting, and a county, city, or village from enforcing, any provision in a county shoreland or subdivision ordinance that regulates the location, maintenance, expansion, replacement, repair, or relocation of a nonconforming building if the provision is more restrictive than the standards for nonconforming buildings under ch. NR 115; or the construction of a structure or building on a substandard lot if the provision is more restrictive than the standards for substandard lots under ch. NR 115. NR 115.01 Note2011 Wisconsin Act 170 also created other provisions that affect how a county regulates nonconforming uses and buildings, premises, structures, or fixtures under its general zoning ordinance.

Register January 2010 No. 649, eff. 2-1-10. NR 115.02NR 115.02 Applicability. The provisions of this chapter apply to county regulation of the use and development of unincorporated shoreland areas, and to annexed or incorporated areas except as provided in s. 59.692 (7), Stats. Unless specifically exempted by law, all cities, villages, towns, and counties are required to comply with, and obtain all necessary permits under, local shoreland ordinances. The construction, reconstruction, maintenance or repair of state highways and bridges carried out under the direction and supervision of the Wisconsin department of transportation is not subject to local shoreland zoning ordinances if s. 30.2022 (1m), Stats., applies. NR 115.02 NoteNote: Under section 59.692 (7), Stats., areas annexed after May 7, 1982 and areas incorporated after April 30, 1994 were generally subject to the county shoreland zoning ordinances in effect on the date of annexation or incorporation. Effective December 14, 2013, 2013 Wis. Act 80 repealed s. 59.692 (2m) (c) and (7), amended s. 59.692 (6m), and created ss. 61.353 and 62.233. 2013 WI Act 80 is retroactive as well as prospective, and applies to all shorelands areas annexed since May 7, 1982 or incorporated since April 30, 1994.

For the purpose of this chapter: NR 115.03(1d)(1d) “Access and viewing corridor” means a strip of vegetated land that allows safe pedestrian access to the shore through the vegetative buffer zone. NR 115.03(1h)(1h) “Boathouse” means a permanent structure used for the storage of watercraft and associated materials and includes all structures which are totally enclosed, have roofs or walls or any combination of these structural parts. NR 115.03(1p)(1p) “Building envelope” means the three dimensional space within which a structure is built. NR 115.03(2)(2) “County zoning agency” means that committee or commission created or designated by the county board under s. 59.69 (2) (a), Stats., to act in all matters pertaining to county planning and zoning. NR 115.03(3)(3) “Department” means the department of natural resources. NR 115.03(3m)(3m) “Existing development pattern” means that principal structures exist within 250 feet of a proposed principal structure in both directions along the shoreline. NR 115.03(4)(4) “Flood plain” means the land which has been or may be hereafter covered by flood water during the regional flood. The flood plain includes the floodway and the flood fringe as those terms are defined in ch. NR 116. NR 115.03(4g)(4g) “Impervious surface” means an area that releases as runoff all or a majority of the precipitation that falls on it. “Impervious surface” excludes frozen soil but includes rooftops, sidewalks, driveways, parking lots, and streets unless specifically designed, constructed, and maintained to be pervious. NR 115.03(4r)(4r) “Mitigation” means balancing measures that are designed, implemented and function to restore natural functions and values that are otherwise lost through development and human activities. NR 115.03(5)(5) “Navigable waters” means Lake Superior, Lake Michigan, all natural inland lakes within Wisconsin and all streams, ponds, sloughs, flowages and other waters within the territorial limits of this state, including the Wisconsin portion of boundary waters, which are navigable under the laws of this state. Under s. 281.31 (2) (d), Stats., notwithstanding any other provision of law or administrative rule promulgated thereunder, shoreland ordinances required under s. 59.692, Stats., and this chapter do not apply to lands adjacent to farm drainage ditches if: NR 115.03(5)(a)(a) Such lands are not adjacent to a natural navigable stream or river; NR 115.03(5)(b)(b) Those parts of such drainage ditches adjacent to such lands were nonnavigable streams before ditching or had no previous stream history; and NR 115.03(5)(c)(c) Such lands are maintained in nonstructural agricultural use. NR 115.03 NoteNote: In Muench v. Public Service Commission, 261 Wis. 492 (1952), the Wisconsin Supreme Court held that a stream is navigable in fact if it is capable of floating any boat, skiff, or canoe, of the shallowest draft used for recreational purposes. In DeGayner and Co., v. Department of Natural Resources, 70 Wis. 2d 936 (1975), the court also held that a stream need not be navigable in its normal or natural condition to be navigable in fact. The DeGayner opinion indicates that it is proper to consider artificial conditions, such as beaver dams, where such conditions have existed long enough to make a stream useful as a highway for recreation or commerce, and to consider ordinarily recurring seasonal fluctuations, such as spring floods, in determining the navigability of a stream. NR 115.03(6)(6) “Ordinary high-water mark” means the point on the bank or shore up to which the presence and action of surface water is so continuous as to leave a distinctive mark such as by erosion, destruction or prevention of terrestrial vegetation, predominance of aquatic vegetation, or other easily recognized characteristic. Where the bank or shore at any particular place is of such character that it is difficult or impossible to ascertain where the point of ordinary high-water mark is, recourse may be had to the opposite bank of a stream or to other places on the shore of a lake or flowage to determine whether a given stage of water is above or below the ordinary high-water mark. NR 115.03(7)(7) “Regional flood” means a flood determined to be representative of large floods known to have generally occurred in Wisconsin and which may be expected to occur on a particular stream because of like physical characteristics once in every 100 years. NR 115.03 NoteNote: The regional flood is based upon a statistical analysis of streamflow records available for watershed and/or an analysis of rainfall and runoff characteristics in the general watershed region. The flood frequency of the regional flood is once in every 100 years. In any given year, there is a 1% chance that the regional flood may occur. During a typical 30-year mortgage period, the regional flood has a 26% chance of occurring.
NR 115.03(7m)(7m) “Routine maintenance of vegetation” means normally accepted horticultural practices that do not result in the loss of any layer of existing vegetation and do not require earth disturbance. NR 115.03(8)(8) “Shorelands” means lands within the following distances from the ordinary high-water mark of navigable waters: 1,000 feet from a lake, pond or flowage; and 300 feet from a river or stream or to the landward side of the flood plain, whichever distance is greater. NR 115.03(9)(9) “Shoreland-wetland zoning district” means a zoning district, created as a part of a county shoreland zoning ordinance, comprised of shorelands that are designated as wetlands on the Wisconsin wetland inventory maps prepared by the department. NR 115.03(10)(10) “Special exception (conditional use)” means a use which is permitted by a shoreland zoning ordinance provided that certain conditions specified in the ordinance are met and that a permit is granted by the board of adjustment or, where appropriate, the planning and zoning committee or county board. NR 115.03(11)(11) “Unnecessary hardship” means that circumstance where special conditions affecting a particular property, which were not self-created, have made strict conformity with restrictions governing area, setbacks, frontage, height or density unnecessarily burdensome or unreasonable in light of the purposes of the zoning ordinance. NR 115.03(13)(13) “Wetlands” means those areas where water is at, near or above the land surface long enough to be capable of supporting aquatic or hydrophytic vegetation, and which have soils indicative of wet conditions.

Counties shall adopt shoreland ordinances that include zoning regulations for shoreland-wetland zoning districts. NR 115.04(2)(2) Amendment of Shoreland-wetland maps and zoning districts. NR 115.04(2)(a)(a) County review of wetland inventory map amendments. After the department amends final Wisconsin wetland inventory maps: NR 115.04(2)(a)1.1. The department shall transmit to the county zoning agency designated under s. 59.69 (2) (a), Stats., digital files or paper copies of amended wetland inventory maps for that county. NR 115.04(2)(a)2.2. If the county believes that the amended maps are inaccurate, within 30 days of receiving the amended maps the county shall note discrepancies on the maps with an accompanying narrative explaining the amended problem areas and return a copy of the notated map and narrative to the department. NR 115.04(2)(a)3.3. The department shall, at department expense, consult available soil survey maps and conduct on-site inspections, if appropriate, in order to evaluate the county recommendations, and shall then prepare final amended Wisconsin wetland inventory maps for that county. NR 115.04 NoteNote: As of 1985 all counties adopted official wetland zoning maps and amendments occur as accuracy increases.
NR 115.04(2)(b)(b) County amendment of shoreland-wetland maps and zoning districts. NR 115.04(2)(b)1.1. Within 6 months after receipt of final amended Wisconsin wetland inventory maps for that county from the department, a county shall zone all shorelands designated as wetlands on the amended Wisconsin wetland inventory maps in a shoreland-wetland zoning district. If a county fails to zone all shoreland-wetlands within this 6 month period, s. NR 115.06 (3) (b) shall apply. NR 115.04(2)(b)2.2. Ordinance text and map amendments creating or amending shoreland-wetland zoning districts shall be referred to the county zoning agency for public hearing as required by s. 59.69 (5) (e) 2., Stats. NR 115.04 NoteNote: Where an apparent discrepancy exists between a shoreland-wetland district shown on an amended map and actual field conditions, the county shall contact the department to determine if the amended map is in error. If the department determines that a particular area was incorrectly mapped as wetland or meets the wetland definition but was not shown as wetland on the map, the county shall have the authority to immediately grant or deny a shoreland zoning permit in accordance with the applicable regulations based on the department determination as to whether the area is wetland. In order to correct wetland mapping errors on the official zoning map, an official map amendment must be initiated within a reasonable period of time, not to exceed one year following the determination.
NR 115.04(2)(b)3.3. At least 10 days prior to the public hearing, the county shall provide the appropriate regional office of the department with a copy of the proposed text and map amendments and with written notice of the public hearing. NR 115.04(2)(c)1.1. Official ordinance amendments are required for any proposed change in shoreland-wetland zoning. Such amendments shall be made in accordance with provisions of s. 59.69 (5) (e), Stats. Official amendments to the ordinance text shall be made promptly. Provided the ordinance text is promptly amended, a county may amend its official map within a reasonable period of time not to exceed one year following the change in shoreland-wetland zoning. NR 115.04(2)(c)2.2. The county clerk shall submit a copy of every proposed amendment to a shoreland-wetland zoning district to the appropriate regional office of the department within 5 days of the filing of such proposed amendment with the clerk. NR 115.04(2)(c)3.3. All proposed text and map amendments to shoreland-wetland zoning districts shall be referred to the county zoning agency for a public notice and hearing as required by s. 59.69 (5) (e) 2., Stats. The appropriate regional office of the department shall be provided with written notice of the public hearing at least 10 days prior to such hearing. NR 115.04(2)(c)4.4. In order to ensure that the shoreland protection objectives found in s. 281.31, Stats., will be accomplished by the county shoreland ordinance, a county shall not rezone a shoreland-wetland zoning district, or portion thereof, if the proposed rezoning may result in a significant adverse impact upon any of the following: NR 115.04(2)(c)4.b.b. Maintenance of dry season stream flow, or the discharge of groundwater to a wetland, the recharge of groundwater from a wetland to another area, or the flow of groundwater through a wetland;
