6120.3300 - Minnesota Administrative Rules Page 10 of 11 � �waters frontage,must eittier 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.Those with water-oriented needs must meet the following standards: A. In addition to meeting impervious coverage limits,setbacks,and other zoning standards presented elsewhere in parts 6120.2500 to 61203900,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 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. (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 needed 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. If 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. Subp. 11. Storm water management. Local governments must consider proper storm water management in all reviews,approvals,and permit issuances under shoreland management controls adopted under parts 6120.2500 to 6120.3900.The following general and specific standards must be incorporated into local government shoreland management controls and their administration. A. The following are general standards: (1) When possible,existing natural drainageways,wetlands,and vegetated soil surfaces must be used to convey,store,filter,and retain storm water runoff before discharge to public waters. (2) Development must 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. (3) When development density,topographic features,and soil and vegetation conditions are not sufficient to adequately handle storm water 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 must be given to designs using surface drainage,vegetation,and infiltration rather than buried pipes and human-made materials and facilities. B. The following aze specific standards: (1) Impervious surface coverage of lots must not exceed 25 percent of the lot area. (2) When constructed facilities are used for storm water management,they must be designed and installed consistent with the field office technical guide of the local soil and water conservation districts. (3) New constructed storm water outfalls to public waters must provide for filtering or settling of suspended solids and skimming of surface debris before discharge. https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014
