Setbacks are 10' on each side and 35' from the rear(street) and average lakeshore setback on the lake side. The property is located in Tier 1 of the Stormwater Quality Overlay District which allows 25% of the gross area of the lot to be covered in hardcover. According to Hennepin County mapping system the lots are 17,890 and 17,085 square feet, respectively. Historically records show the two lots were required to be combined with the 1965 subdivision and then again in 1972 when the current home was being proposed. For whatever reason, that was never completed and the house at 1415 Park Drive was constructed over a property line. As a result, the home is considered a non-conforming structure. After consulting with the City's legal counsel, non-conforming structures cannot be expanded, i.e. construction of a deck would not be allowed. No new permits can be issued for this property, only permits to allow maintenance i.e. windows, siding, etc. As we discussed, it is unclear even if the lots were combined if a deck could be constructed due average lakeshore setback, hardcover, potential wetlands, etc. If the lots were combined, the property would not be allowed to be subdivided in the future as it would result in two non-conforming lots. If the lots remain two separate PIDs, according to the current City Code regarding Lots of Record [section 78-72(c)(2)] and Minnesota Rules, Chapter 6210, Subpart 2a, Item F, if the existing house was removed a home could be constructed on each lot if it met the setbacks for the LR-1 B zoning district. A copy of the code sections are attached. If you have any questions, please don't hesitate to contact me. Sincerely, OFORONO ` IY�U� Christine Mattson Planning Assistant Enclosures Municode Page 1 of 3 . � Sec. 78-72. Lots of record. (a) A lot of record is any lot for which a deed or registered land survey has been recorded in the office of the register of deeds or the registrar of titles for Hennepin County prior to January 1, 1975, and after approval by the council if required. (b) A lot of record located within an R (Residential) or RR (Rural Residential) district but not within the Shoreland Overlay district, RS Seasonal Recreational district, or any of the LR- Lakeshore Residential districts, which does not meet the requirements of this chapter as to area or width may be utilized for a single-family detached dwelling purpose, provided that in the judgment of the council or administrative approval by the planning director, such use does not adversely affect public health or safety and the following requirements are met: (�) In R districts of one acre or less and served by public sanitary sewer. A lot of record existing upon January 1, 1975, in any R district of the city of up to and including one acre, which lot is serviced by public sanitary sewer and which does not meet the requirements of this chapter as to area or width only, may be utilized for single-family detached dwelling purposes without council approval if all other requirements of the underlying zoning district are met, including but not limited to required yards, setbacks, lot coverage by structures, hardcover, etc. However, the lot of record shall not be more intensely developed unless combined with one or more abutting lots or portions so as to create a lot meeting the requirements of this chapter. (2) In R or RR districts of greater than one acre and served by public sanitary sewer. A lot of record in any R or RR district in the city in excess of one acre which does not meet the requirements of this chapter as to area or width only may be utilized for single- family detached dwelling purposes by administrative approval if the planning director finds that the following conditions are met: a• It is at least one acre in size, and the average width of the lot is at least 100 feet; b• It is served by public sanitary sewer; and �• It otherwise meets the requirements of this chapter or other applicable Code provisions. �3) In R or RR districts not served by public sanitary sewer. A lot of record in any R or RR district in the city not served by public sanitary sewer must meet the area and width requirements of this chapter and shall not be utilized for single-family detached dwelling purposes without council approval. Administrative approval may be granted for a lot of record not meeting the lot area and width requirements if the planning director finds that the following conditions are met: a• The lot area and lot width each meet at least 50 percent of the district standard. b• Suitable primary and alternate septic sites are identified on the property and are protected from future development by execution of a covenant. �• All other zoning ordinance requirements must be met, including but not limited to the following: �• Setbacks. 2• Hardcover. 3• Lot coverage by structures. 4• Accessory structure requirements. (�) A lot of record located in any shoreland district, including the Shoreland Overlay district, RS Seasonal Recreational district, and any of the LR- Lakeshore Residential districts, that does http://library.municode.com/print.aspx?h=&clientID=13094&HTMRequest=http%3a%2f... 4/21/2014 Municode Page 2 of 3 , . not meet the requirements of this chapter for lot size or lot width shall be subject to the following regulations: (�) A nonconforming single lot of record may be allowed as a building site without variances from lot size and width requirements, provided that: a• All setback requirements can be met; b• A Type 1 sewage treatment system consistent with Minnesota Rules, chapter 7080, can be installed or the lot is connected to a public sewer; and �• The impervious surface coverage meets all hardcover location and square footage restrictions of this chapter and the total square footage of hardcover does not exceed 25 percent of the entire lot area. d• All other zoning district standards can be met. �2) In a group of two or more contiguous lots of record under a common ownership, an individual lot must be considered as a separate parcel of land for the purpose of sale or development, if it meets the following requirements: a• The lot must be at least 66 percent of the dimensional standard for lot width and lot size for the shoreland classification consistent with Minnesota Rules, chapter 6120; b• The lot must be connected to a public sewer, if available, or must be suitable for the installation of a Type 1 sewage treatment system consistent with Minnesota Rules, chapter 7080, and local government controls; and �• Impervious surface coverage must meet all hardcover location and square footage restrictions of this chapter and the total square footage of hardcover must not exceed 25 percent of the entire lot area; and d• Development of the lot must be consistent with the comprehensive plan. (3) A lot subject to either subsections 78-72(c)(1)or(2) remains subject to the hardcover restrictions of this chapter, as follows: a• Where the hardcover square footage allotment as calculated based on the assigned tier exceeds 25 percent of the entire lot area, hardcover shall be limited to 25 percent of the entire lot area. b• No portion of the impervious surface square footage allowed shall be placed within in 75 feet of a lake OHWL or tributary bank, except for those items normally allowed in such location as regulated elsewhere in this chapter. (4) A lot subject to subsection 78-72(c)(2) not meeting the requirements of subsection 78- 72(c)(2) must be combined with the one or more contiguous lots so they equal one or more conforming lots as much as possible. (5) Notwithstanding subsection 78-72(c)(2), contiguous nonconforming lots of record in shoreland areas under a common ownership must be able to be sold or purchased individually if each lot contained a habitable residential dwelling at the time the lots came under common ownership and the lots are suitable for, or served by, a sewage treatment system consistent with the requirements of Minn. Stat. § 115.55 and Minnesota Rules, chapter 7080, or connected to a public sewer. (6) In all variance requests, zoning and building permit applications or conditional use requests, the property owner shall address, when determined as appropriate by the city engineer or city staff, stormwater runoff management, reduction of impervious surfaces, setback increases, restoration of wetlands, vegetative buffers, sewage treatment and water supply capabilities, and other conservation-designed actions. (�) A portion of a conforming lot may be separated from an existing parcel as long as the remainder of the existing parcel meets the lot size and sewage treatment requirements of the zoning district for a new lot and the newly created parcel is combined with an adjacent parcel. http://library.municode.com/print.aspx?h=&clientID=13094&HTMRequest=http%3a%2f... 4/21/2014 Municode Page 3 of 3 r � (Code 1984, § 10.03(6)(A); Ord.

Subpart l. Purpose. To manage the effects of shoreland and water surface crowding,to prevent pollution of surface and ground waters of the state,to provide ample space on lots for sewage treatment systems,to minimize flood damages,to maintain property values,to maintain historic values of significant historic sites,and to maintain natural characteristics of shorelands and adjacent water areas,shoreland controls must regulate lot sizes,placement of structures,and alterations of shoreland areas. Subp.2. Residential lot size. All single,duplex,triplex,and quad residential lots created after the date of enachnent of the local shoreland controls must meet or exceed the dimensions presented in subparts 2a and 2b,and the following: A. Lots must not be occupied by any more dwelling units than indicated in subparts 2a and 2b. Residential subdivisions with dwelling unit densities exceeding those in the tables in subparts 2a and 2b can only be allowed if designed and approved as residential planned unit developments under part 61203800.Only land above the ordinary high water level of public waters can be used to meet lot area standards,and lot width standards must be met at both the ordinary high water level and at the building line. The sewer lot area dimensions in subpart 2a, items D to F can only be used if publicly owned sewer system service is available to the property. B. On natural environment lakes,subdivisions of duplexes,triplexes,and quads must also meet the following standards: (1) Each building must be set back at least 200 feet from the ordinary high water level. (2) Each building must have common sewage treatment and water systems that serve all dwelling units in the building. (3) Watercraft docking facilities for each lot must be centralized in one location and serve all dwelling units in the building. (4) No more than 25 percent of a lake's shoreline can be in duplex,triplex, or quad developments. C. One guest cottage may be allowed in local controls on lots meeting or exceeding the duplex dimensions presented in subparts 2a and 2b if the controls also require all of the following standards to be met: (1) For lots exceeding the minimum lot dimensions of duplex lots,the guest cottage must be located within the smallest duplex-sized lot that could be created including the principal dwelling unit. (2) A guest cottage must not cover more than 700 square feet of land surface and must not exceed 15 feet in height. (3) A guest cottage must be located or designed to reduce its visibility as viewed from public waters and adjacent shorelands by vegetation,topography,increased setbacks,color,or other means acceptable to the local unit of government,assuming summer leaf-on conditions. D. Lots of record in the office of the county recorder on the date of enactment of local shoreland controls that do not meet the requirements of items A to E and subparts 2a and 2b may be allowed as building sites without variances from lot size requirements provided the use is permitted in the zoning district,the lot has been in separate ownership from abutting lands at all times since it became substandard,was created compliant with official controls in effect at the time,and sewage treatment and setback requirements of the shoreland controls are met.Necessary variances from setback requirements must be obtained before any use,sewage treahnent system,or building permits aze issued for the lots.In evaluating all the variances,boards of adjustment shall consider sewage treahnent and water supply capabilities or constraints of the lots and shall deny the variances if adequate facilities cannot be provided. If,in a group of two or more contiguous lots under https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014 6120.3300 - Minnesota Administrative Rules Page 2 of 11 �� the same ownership,any'individual lot does not meet the requirements of items A to E and subparts 2a and 2b,the lot must not be considered as a separate pazcel of land for the purposes of sale or development.The lot must be combined with the one or more contiguous lots so they equal one or more parcels of land,each meeting the requirements of items A to E and subparts 2a and 2b as much as possible.Local shoreland controls may set a minimum size for nonconforming lots or impose their restrictions on their development. E. If allowed by local governments,lots intended as controlled accesses to public waters or recreation areas for use by owners of nonriparian lots within subdivisions must meet or exceed the following standards: (1) They must meet the width and size for residential lots,and be suitable for the intended uses of controlled access lots. If docking,mooring,or over-water storage of watercraft is to be allowed at a controlled access lot,then the width of the lot must be increased by the percent of the requirements for riparian residential lots for each watercraft provided for by covenant beyond six,consistent with the following table: Controlled Access Lot Frontage Requirements Ratio of lake size to shore length(acres/mile) Required increase in frontage(percent) Less than 100 25 100-200 20 201-300 15 301-400 10 Greater than 400 5 (2) They must be jointly owned by all purchasers of lots in the subdivision or by all purchasers of nonriparian lots in the subdivision who are provided riparian access rights on the access lot. (3) Covenants or other equally effective legal instruments must be developed that specify which lot owners have authority to use the access lot and what activities are allowed. T'he activities may include watercraft launching,loading,storage, beaching,mooring,or docking.They must also include other outdoor recreational activities that do not significantly conflict with general public use of the public water or the enjoyment of normal property rights by adjacent property owners.Examples of the nonsignificant conflict activities include swimming, sunbathing,or picnicking. The covenants must limit the total number of vehicles allowed to be parked and the total number of watercra8 allowed to be continuously moored,docked,or stored over water, and must require centralization of all common facilities and activities in the most suitable locations on the lot to minimize topographic and vegetation alterations.They must also require all parking areas,storage buildings,and other facilities to be screened by vegetation or topography as much as practical from view from the public water,assuming summer,leaf-on conditions.

Placement and height of structures and facilities on lots. When more than one setback requirement applies to a site, structures and facilities must be located to meet all setbacks.The placement of structures and other facilities on all lots must be managed by shoreland controls as follows: A. Structure setbacks.The following minimum setbacks presented in the following table for each class of public waters apply to all structures,except water- oriented accessory structures and facilities that are managed according to item H: (1) Structure setback standards https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014 6120.3300 - Minnesota Administrative Rules Page 5 of 11 � Class � � Ordinary high water Setback from top level setback(feet) of bluff(feet) Unsewered Sewered Natural environment 150 150 30 Recreational development 100 75 30 General development 75 50 30 Remote river segments 200 200 30 Forested and transition river segments 150 150 30 Agricultural,urban,and tributary river 100 50 30 segments (2) Exceptions to structure setback standards in subitem(1).Where structures exist on the adjoining lots on both sides of a proposed building site,structure setbacks may be altered without a variance to conform to the adjoining setbacks provided the proposed building site is not located in a shore impact zone or in a bluff impact zone. B. High water elevations.In addition to the setback requirements of item A, local shoreland controls must regulate placement of structures in relation to high water elevation.Where state-approved,local flood plain management controls exist,structures must be placed at an elevation consistent with the controls. Where these controls do not exist,the elevation to which the lowest floor, including basement, is placed or flood- proofed must be determined as follows: (1) For lakes,by placing the lowest floor at a level at least three feet above the highest known water level,or three feet above the ordinary high water level,whichever is higher.In instances where lakes have a history of extreme water level fluctuations or have no outlet capable of keeping the lake level at or below a level three feet above the ordinary high water level,local controls may require structures to be placed higher. (2) For rivers and streams,by placing the lowest floor at least three feet above the flood of record,if data are available. If data are not available,by placing the lowest floor at least three feet above the ordinary high water level,or by conducting a technical evaluation to determine effects of proposed construction upon flood stages and flood flows and to establish the flood protection elevation.Under all tl�ree approaches, technical evaluations must be done consistent with parts 6120.5000 to 6120.6200 governing the management of flood plain areas.If more than one approach is used,the highest flood protection elevation determined must be used for placing structures and other facilities. (3) Water-oriented accessory structures may have the lowest floor placed lower than the elevation determined in this subpart if the structure is constructed of flood- resistant materials to the elevation,electrical and mechanical equipment is placed above the elevation and,if long duration flooding is anticipated,the structure is built to withstand ice action and wind-driven waves and debris. C. Bluff impact zones. Structures and accessory facilities,except stairways and landings,must not be placed within bluff impact zones. D. Steep slopes.Local government officials must evaluate possible soil erosion impacts and development visibility from public waters before issuing a permit for construction of sewage treatment systems,roads,driveways, structures,or other improvements on steep slopes. When determined necessaty,conditions must be attached to issued permits to prevent erosion and to preserve existing vegetation screening of structures,vehicles,and other facilities as viewed from the surface of public waters, assuming summer,leaf-on vegetation. E. Proximity to unplatted cemeteries and significant historic sites.No structure may be placed nearer than 50 feet from the boundary of an unplatted cemetery protected under Minnesota Statutes,section 307.08,unless necessary approval is obtained from the Minnesota State Archaeologist's Office.No structure may be placed on a significant historic site in a manner that affects the values of the site unless adequate information about the site has been removed and documented in a public repository. https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014 6120.3300 - Minnesota Administrative Rules Page 6 of 11 ' � F. Proximity to roads and highways.No structure may be placed nearer than 50 feet from the right-of-way line of any federal,state,or county highway;or 20 feet from the right-of-way line of any town road,public street,or others not classified. G. Height.All structures in residential districts in cities,except churches and nonresidential agricultural structures,must not exceed 25 feet in height. H. Accessory structures and facilities.All accessory structures and facilities, except those that are water-oriented,must meet or exceed structure setback standards.If allowed by local government controls,each residential lot may have one water-oriented accessory structure or facility located closer to public waters than the structure setback if all of the following standards are met: (1) The structure or facility must not exceed ten feet in height,exclusive of safety rails,and cannot occupy an area greater than 250 square feet.Detached decks must not exceed eight feet above grade at any point. (2) 'The setback of the structure or facility from the ordinary high water level must be at least ten feet. (3) The structure or facility must be treated to reduce visibility as viewed from public waters and adjacent shorelands by vegetation,topography,increased setbacks, color,or other means acceptable to the local unit of government,assuming summer,leaf- on conditions. (4) T'he roof may be used as a deck with safety rails,but must not be enclosed or used as a storage area. (5) The structure or facility must not be designed or used for human habitation and must not contain water supply or sewage treatment facilities. (6) As an alternative for general development and recreational development waterbodies,water-oriented accessory structures used solely for watercraft storage,and including storage of related boating and water-oriented sporting equipment,may occupy an area up to 400 square feet provided the maximum width of the structure is 20 feet as measured parallel to the configuration of the shoreline. (7) Any accessory structures or facilities not meeting the above criteria,or any additional accessory structures or facilities must meet or exceed structure setback standards. I. Stairways,lifts,and landings. Stairways and lifts are the prefened alternative to major topographic alterations for achieving access up and down bluffs and steep slopes to shore areas. Stairways and lifts must meet the following design requirements: (1) Stairways and lifts must not exceed four feet in width on residential lots.Wider stairways may be used for commercial properties,public open-space recreational properties,and planned unit developments. (2) Landings for stairways and lifts on residential lots must not exceed 32 square feet in area. Landings larger than 32 square feet may be used for commercial properties,public open-space recreational properties,and planned unit developments. (3) Canopies or roofs are not allowed on stairways, lifts,or landings. (4) Stairways,lifts,and landings may be either constructed above the ground on posts or pilings,or placed into the ground,provided they are designed and built in a manner that ensures control of soil erosion. (5) Stairways, lifts,and landings must be located in the most visually inconspicuous portions of lots,as viewed from the surface of the public water assuming summer,leaf-on conditions,whenever practical. (6) Facilities such as ramps, lifts,or mobility paths for persons with physical disabilities are also allowed for achieving access to shore areas,provided that the dimensional and performance standards of subitems(1)to(5)are complied with in addition to the requirements of chapter 1341. J. Decks.Except as provided in item H,decks must meet the structure setback standards.Decks that do not meet setback requirements from public waters may be allowed without a variance to be added to structures existing on the date the shoreland https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014 6120.3300 - Minnesota Administrative Rules Page 7 of 11 � ' structure setbacks were established by ordinance,if all of the following criteria and standards are met: (1) a thorough evaluation of the property and structure reveals no reasonable location for a deck meeting or exceeding the existing ordinary high water level setback of the structure; (2) the deck encroachment toward the ordinary high water level does not exceed 15 percent of the existing shoreline setback of the structure from the ordinary high water level or does not encroach closer than 30 feet,whichever is more restrictive;and (3) the deck is constructed primarily of wood,and is not roofed or screened. Subp. 4. Shoreland alterations. Vegetative alterations and excavations or grading and filling necessary for the construction of structures and sewage treatment systems under validly issued permits for these facilities are exempt from the vegetative alteration standards in this subpart and separate permit requirements for grading and filling. However,the grading and filling conditions of this subpart must be met for issuance of permits for structures and sewage treatment systems.Alterations of vegetation and topography must be controlled by local governments to prevent erosion into public waters, fix nutrients,preserve shoreland aesthetics,preserve historic values,prevent bank slumping,and protect fish and wildlife habitat.Public roads and parking areas,as regulated by subpart 5,are exempt from the provisions of this part. A. Removal or alterations of vegetation,except for forest management or agricultural uses as provided for in subparts 7 and 8,is allowed according to the following standards: (1) Intensive vegetation clearing within the shore and bluff impact zones and on steep slopes is not allowed.Intensive vegetation clearing outside of these areas is allowed if the activity is consistent with the forest management standards in subpart 8. (2) Limited clearing of trees and shrubs and cutting,pruning,and trimming of trees to accommodate the placement of stairways and landings,picnic areas,access paths, livestock watering areas,beach and watercraft access areas,and permitted water- oriented accessory structures or facilities,as well as providing a view to the water from the principal dwelling site, in shore and bluff impact zones and on steep slopes is allowed, provided that: (a) the screening of structures,vehicles,or other facilities as viewed from the water,assuming summer,leaf-on conditions,is not substantially reduced; (b) along rivers,existing shading of water surfaces is preserved;and (c) the above provisions are not applicable to the removal of trees, limbs,or branches that are dead,diseased,or pose safety hazards. (3) Use of fertilizer and pesticides in the shoreland management district must be done in such a way as to minimize runoff into the shore impact zone or public water by the use of earth,vegetation,or both. B. Before grading or filling on steep slopes or within shore or bluff impact zones involving the movement of more than ten cubic yards of material or anywhere else in a shoreland area involving movement of more than 50 cubic yards of material, it must be established by local official permit issuance that all of the following conditions will be met. The following conditions must also be considered during subdivision,variance, building permit,and other conditional use permit reviews. (1) Before authorizing any grading or filling activity in any type 2,3,4, 5, 6,7,or 8 wetland,local officials must consider how extensively the proposed activity would affect the following functional qualities of the wetland: (a) sediment and pollutant trapping and retention; (b) storage of surface runoff to prevent or reduce flood damage; (c) fish and wildlife habitat; (d) recreational use; (e) shoreline or bank stabilization;or https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014 6120.3300 - Minnesota Administrative Rules Page 8 of 11 � � (fl noteworthiness,including special qualities such as historic significance,critical habitat for endangered plants and animals,or others. T'his evaluation must also include a determination of whether the wetland alteration being proposed requires permits,reviews,or approvals by other local,state,or federal agencies such as a watershed district,the Minnesota Department of Natural Resources,or the United States Army Corps of Engineers. (2) Alterations must be designed and conducted in a manner that ensures only the smallest amount of bare ground is exposed for the shortest time possible. (3) Mulches or similar materials must be used,where necessary,for temporary bare soil coverage,and a permanent vegetation cover must be established as soon as possible. (4) Methods to minimize soil erosion and to trap sediments before they reach any surface water feature must be used. (5) Altered areas must be stabilized to acceptable erosion control standards consistent with the field office technical guides of the local soil and water conservation districts and the United States Soil Conservation Service. (6) Fill or excavated material must not be placed in a manner that creates an unstable slope. (7) Plans to place fill or excavated material on steep slopes must be reviewed by qualified professionals for continued slope stability and must not create finished slopes of 30 percent or greater. (8) Fill or excavated material must not be placed in bluff impact zones.

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 Service. C. Animal feedlots as defined by the Minnesota Pollution Control Agency, where allowed by zoning district designations,must be reviewed as conditional uses and must meet the following standards: (1) 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 waters basins. (2) 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. (3) A certificate of compliance,interim permit,or animal feedlot permit, when required by parts 7020.0100 to 7020.1900,must be obtained by the owner or operator of an animal feedlot. D. Use of fertilizer,pesticides,or animal wastes within shorelands must 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. Subp.8. Forest management standards. The harvesting of timber and associated reforestation or conversion of forested use to a nonforested use must be conducted consistent with the following standards: A. Timber harvesting 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. If allowed by local governments,forest land conversion to another use requires issuance of a conditional use permit and adherence to the following standards: (1) shore and bluff impact zones must not be intensively cleared of vegetation;and (2) an erosion and sediment control plan is developed and approved by the local soil and water conservation district before issuance of a conditional use permit for the conversion. C. Use of fertilizer,pesticides,or animal wastes within shorelands must 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. Subp.9. Extractive use standards. Processing machinery must be located consistent with setback standards for structures from ordinary high water levels of public waters and from bluffs. An extractive use site development and restoration plan must be developed,approved by the local government,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. Subp. 10. Standards for commercial,industrial,public,and semipublic uses. 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.Uses without water-oriented needs must be located on lots or parcels without public waters frontage,or,if located on lots or pazcels with public https://www.revisor.mn.gov/rules/?id=6120.3300 4/22/2014 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 6120.3300 - Minnesota Administrative Rules Page 11 of 11 Subp. 12.
