(A) Standards for commercial, industrial, public and semi-public uses.
(1) Surface water-oriented commercial uses and industrial, public or semi-public uses with similar needs to have access to and use of public waters may be located on parcels or lots with frontage on public waters. Those uses with water-oriented needs must meet the following standards.
(a) In addition to meeting impervious coverage limits, setbacks and other zoning standards in this chapter, the uses must be designed to incorporate topographic and vegetative screening of parking areas and structures.
(b) Uses that require short-term watercraft mooring for patrons must centralize these facilities and design them to avoid obstructions of navigation and to be the minimum size necessary to meet the need.
(c) Uses that depend on patrons arriving by watercraft may use signs and lighting to convey needed information to the public, subject to the following general standards.
1. No advertising signs or supporting facilities for signs may be placed in or about public waters. Signs conveying information or safety messages may be placed in or on public waters by a public authority or under a permit issued by the County Sheriff.
2. Signs may be placed, when necessary, within the shore impact zone if they are designed and sized to be the minimum necessary to convey need information. They must only convey the location and name of the establishment and the general types of goods or services available. The signs must not contain other detailed information, such as product brands and prices, must not be located higher than ten feet above the ground, and must not exceed 32 square feet in size. In illuminated by artificial lights, the lights must be shielded or directed to prevent illumination out across public waters.
3. Other outside lighting may be located within the shore impact zone or over public waters if it is used primarily to illuminate potential safety hazards and is shielded or otherwise directed to prevent direct illumination out across public waters. This does not preclude use of navigational lights.
(2) Uses without water-oriented needs must be located on lots or parcels without public water frontage, or, if located on lots or parcels with public waters frontage, must either be set back double the normal ordinary high water level setback or be substantially screened from view from the water by vegetation or topography, assuming summer, leaf-on conditions.
(B) Agricultural use standards.
(1) General cultivation farming, grazing, nurseries, horticulture, truck farming, sod farming and wild crop harvesting are permitted uses if steep slopes and shore and bluff impact zones are maintained in permanent vegetation or operated under an approved conservation plan (Resource Management Systems) consistent with the field office technical guides of the local soil and water conservation districts or the United States Soil Conservation Services, as provided by a qualified individual or agency. The shore impact zone for parcels with permitted agricultural land uses is equal to a line parallel to and 50 feet from the ordinary high water level.
(2) Animal feedlots must meet the following standards:
(a) New feedlots must not be located in the shoreland of watercourses or in bluff impact zones and must meet a minimum setback of 300 feet from the ordinary high water level of all public water basins; and
(b) Modifications or expansions to existing feedlots that are located within 300 feet of the ordinary high water level or within a bluff impact zone are allowed if they do not further encroach into the existing ordinary high water level setback or encroach on bluff impact zones.
(C) Forest management standards. The harvesting of timber and associated reforestation must be conducted consistent with the provisions of the Minnesota Nonpoint Source Pollution Assessment-Forestry and the provision of Water Quality in Forest Management Best Management Practices in Minnesota.
(D) Extractive use standards.
(1) Site development and restoration plan. An extractive use site development and restoration plan must be developed, approved and followed over the course of operation of the site. The plan must address dust, noise, possible pollutant discharges, hours and duration of operation and anticipated vegetation and topographic alterations. It must also identify actions to be taken during operation to mitigate adverse environmental impacts, particularly erosion, and must clearly explain how the site will be rehabilitated after extractive activities end.
(2) Setbacks for processing machinery. Processing machinery must be located consistent with setback standards for structures from ordinary high water levels of public waters and from bluffs.
(E) Mining of metallic minerals and peat. Mining of metallic minerals and peat, as defined in M.S. §§ 93.44 through 93.51, as they may be amended from time to time, shall be a permitted use provided the provisions of M.S. §§ 93.44 through 93.51, as they may be amended from time to time, are satisfied.
