SECTION 15. SL SHORELAND DISTRICT[1]
Subdivision 1. Findings.
The City finds that the uncontrolled use of shorelands adversely affects the public health, safety, and general welfare by contributing to pollution of Public Waters and by impairing the local tax base.
Subdivision 2. Authority.
The legislature of the State of Minnesota has, in Minnesota Statutes, directed that municipalities with shorelands adopt regulations which comply with State Standards for Municipal Shoreland Management. In furtherance of the policies declared in Minnesota Statutes, section 84.083, and chapters 103A, 103B, 103E to 103G, 115, 116, 394, 396, and 462, the Commissioner provides minimum standards and criteria for the subdivision, use, and development of the shorelands of Public Waters.
Subdivision 3. Intent.
1. The intent of the (SL) Shoreland District is to guide the wise development and utilization of shorelands of Public Waters for the preservation of water quality, natural characteristics, economic values, and the general health, safety and welfare of all Public Waters in the City.
2.The standards and criteria are intended to preserve and enhance the quality of surface waters, conserve the economic and natural environmental values of shorelands, and provide for the wise use of water and related land resources of the state.
Subdivision 4. Purpose.
This section of the Zoning Ordinance is responsive to the cited legislative mandate as administered by the Commissioner of the Minnesota Department of Natural Resources.
Subdivision 5. Applicability.

3. Interpretation of District Boundaries.
A. The boundaries of the Shoreland Management Overlay District shall be the shorelands as defined in this Chapter.
B. The practical limits of shoreland may be less than the statutory limits as set forth in this section whenever the waters involved are bounded by topographic devices which extend landward from the waters for lesser distances and when approved in writing by the Commissioner of the Department of Natural Resources.
C. When interpretation is needed as to the exact location of the boundaries of the Shoreland Management District on the official Zoning Map, where, for example, there appears to be a conflict between a mapped boundary and actual field conditions, the City Engineer shall make the initial interpretation based upon surveys, plans, and other engineering data provided by the person seeking an interpretation; and, based upon the plans and other data available to the City. To the extent that the City is legally required to do so, the initial interpretation of the City Engineer shall be referred to the Commissioner of the Department of Natural Resources who shall make a final determination pursuant to State law and regulations.
D.Only that portion of a property within the boundaries of the Shoreland Overlay District shall be subject to the provisions of this section
Subdivision 6. Disclaimer.
This Ordinance does not imply those areas outside of the shoreland district or land uses permitted within the shoreland district will be free from flooding and flood damages. This Ordinance shall not create liability on the part of the City or any officer or employee thereof for any flood damages that result from reliance upon this Ordinance or any administrative decision lawfully made hereunder.

34.Significant Historic Site. Any archaeological site, standing structure, or other property that meets the criteria for eligibility to the National Register of Historic Places or is listed in the State Register of Historic Sites, or is determined to be an unplatted cemetery that falls under the provisions of Minnesota Statutes, section 307.08. A historic site meets these criteria if it is presently listed on either register or if it is determined to meet the qualifications for listing after review by the Minnesota state archaeologist or the director of the Minnesota Historical Society. All unplatted cemeteries are automatically considered to be significant historic sites.
35.Steep Slope. Land where agricultural activity or development is either not recommended or described as poorly suited due to slope steepness and the site’s soil characteristics, as mapped and described in available county soil surveys or other technical reports, unless appropriate design and construction techniques and farming practices are used in accordance with the provisions of this Chapter.

41.Variance. The same as that term is defined or described in Minnesota Statutes, Chapter 394.
42.Water-Oriented Accessory Structure or Facility. A small, above ground building or other improvement, except stairways, fences, dock, and retaining walls, which, because of the relationship of its use to a surface water feature, reasonably needs to be located closer to Public Waters than the normal structure setback. Examples of such structures and facilities include Boathouses, gazebos, screen houses, fish houses, pump houses, and detached Decks.
43.Wetland. A surface water feature classified as a wetland in the United States Fish and Wildlife Service Circular No. 39 (1971 edition), which is hereby incorporated by reference, is available through the Minitex interlibrary loan system, and is not subject to frequent change
Subdivision 8. Permitted Uses.
See “Appendix A”, which is included at the end of these Shoreland District provisions, and made a part hereof.
Subdivision 9. Conditional Uses.
See “Appendix A”, which is included at the end of these Shoreland District provisions, and made a part hereof.
Subdivision 10. Performance Standards.
1. See “Appendix B”, which is included at the end of these Shoreland District provisions, and made a part hereof.
2. Only land area above the Ordinary High Water Level shall be used to meet the minimum Lot area and width requirements. Lot Width standards shall be met at the water line and at the Building Line. In locations where a principal structure exists on both sides of a proposed building site and a Building Line can be reasonably established, the Zoning Administrator may issue a permit for a lesser distance from the Ordinary High Water Level than those required. Structures located wholly or partly within the shore impact zone shall not be used to establish a Building Line. The landward extension of the shore impact zone and its intersection with the adjacent property line shall be used as the point of reference to establish a Building Line in instances where a principal structure is located partially or wholly within the shore impact zone. For new residential dwellings, the Building Line shall be established by calculating the average Building Line setback for the dwelling located on either side of the proposed residential dwelling and by establishing the Building Line by using the sight line method. The most restrictive Building Line setback shall apply, except that in no case shall the calculated setback be greater than the Building Line setback established for the applicable lake classification. For additions, the Building Line may be established by using a string line between the corner of the dwelling for which the addition is being sought and the lakeward corner closest to the dwelling nearest the proposed addition, by using a sight line, by calculating the average setback of the dwellings located on either side of the proposed addition, or by other reasonable methods which may be employed.
3. Bluff Impact Zones. Structures and accessory facilities, except stairways and landings, shall not be placed within Bluff Impact Zones.
4. Impervious Surface Coverage. Impervious surface coverage of lots must not exceed twenty-five percent (25%) of the lot area and shall only apply to that portion of the lot lying within the Shoreland area.
