A. Placement Of Structures: Structures shall not be located on slopes greater than twelve percent (12%) except by conditional use permit as provided in subsection 11-95-6D of this chapter.
B. Maximum Density: The maximum density in the WSRR District shall not exceed one dwelling unit per lot.
C. Multiple Unit Dwelling Structures: Subdivisions of duplexes, triplexes, and quads shall also meet the following standards:
1. Each building must be set back at least two hundred feet (200') from the ordinary high water level;
2. Each building must have common sewage treatment and water systems in one location and serve all dwelling units in the building; and
3. Watercraft docking facilities for each lot must be centralized in one location and serve all dwelling units in the building.
D. Stormwater Management: Subject to other more restrictive limitations which may be imposed by this title or other provisions of this Code, the following general and specific standards shall apply:
a. When possible, existing natural drainageways, wetlands, and vegetated soil surfaces shall be used to convey, store, filter, and retain stormwater runoff before discharge to public waters.
b. Development shall be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential, and reduce and delay runoff volumes. Disturbed areas must be stabilized and protected as soon as possible and facilities or methods used to retain sediment on the site.
c. When development density, topographic features, and soil and vegetation conditions are not sufficient to adequately handle stormwater runoff using natural features and vegetation, various types of constructed facilities such as diversions, settling basins, skimming devices, dikes, waterways, and ponds may be used. Preference shall be given to designs using surface drainage, vegetation, and infiltration rather than buried pipes and humanmade materials and facilities.
a. When constructed facilities are used for stormwater management, documentation shall be provided by a qualified individual that they are designed and installed consistent with the field office technical guide of the local Soil and Water Conservation Districts.
b. New constructed stormwater outfalls to public waters shall provide for filtering or settling of suspended solids and skimming of surface debris before discharge.
E. Special Provisions For Commercial, Industrial, Public/Semipublic, Agricultural, Forestry And Extractive Uses And Mining Of Metallic Minerals And Peat:
1. Standards For Commercial, Industrial, Public And Semipublic Uses:
a. Surface water oriented commercial uses and industrial, public, or semipublic 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. Subject to other more restrictive limitations which may be imposed by this title, those uses with water oriented needs shall meet the following standards:
(1) In addition to meeting impervious coverage limits, setbacks, and other zoning standards in this title, the uses shall be designed to incorporate topographic and vegetative screening of parking areas and structures;
(2) 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; and
(3) 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:
(A) No advertising signs or supporting facilities for signs may be placed in or upon 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;
(B) Signs may be placed, when necessary, within the shore impact zone if they are designed and sized to be the minimum necessary to convey needed information. They shall only convey the location and name of the establishment and the general types of goods or services available. The signs shall not contain other detailed information such as product brands and prices, shall not be located higher than ten feet (10') above the ground, and shall not exceed thirty two (32) square feet in size. If illuminated by artificial lights, the lights shall be shielded or directed to prevent illumination out across public waters; and
(C) 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.
b. Uses without water oriented needs must be located on lots or parcels without public waters 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.
2. Agriculture Use Standards:
a. 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 Natural Resources Conservation Service, as provided by a qualified individual or agency.
b. The shore impact zone for parcels with permitted agricultural land uses is equal to a line parallel to and fifty feet (50') from the ordinary high water level. The bluff impact zone is equal to the bluff and land located within twenty feet (20') from a bluffline.
c. Animal feedlots shall meet the requirements of this title, as well as the following standards:
(1) New feedlots shall not be located in the WSRR District; and
(2) Modifications or expansions to existing feedlots that are located within three hundred feet (300') of the ordinary high water level or within the 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.
d. Use of fertilizer, pesticides, or animal wastes within the WSRR District shall be done in such a way as to minimize impact on the shore impact zone or public water by proper application or use of earth or vegetation.
3. Forest Management Standards:
a. The harvesting of timber and associated reforestation must be conducted consistent with the provisions of the Minnesota Nonpoint Source Pollution Assessment-Forestry and the provisions of Water Quality in Forest Management "Best Management Practices in Minnesota".
b. Use of fertilizer, pesticides, or animal wastes within the WSRR District shall be done in such a way as to minimize impact on the shore impact zone or public water by proper application or use of earth or vegetation.
4. Extractive Use Standards:
a. Site Development And Restoration Plan: An extractive use site development and restoration plan shall be developed, approved, and followed over the course of operation of the site. The plan shall 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 shall clearly explain how the site will be rehabilitated after extractive activities end.
b. Setbacks For Processing Machinery: Processing machinery shall be located consistent with setback standards for structures from the ordinary high water level and from blufflines.
5. Mining Of Metallic Minerals And Peat: Mining of metallic minerals and peat, as defined in Minnesota Statutes sections 93.44 to 93.51, shall be a permitted use provided the provisions of Minnesota Statutes sections 93.44 to 93.51 are satisfied. (Prior Code § 20-95-9)
