All distances, unless otherwise specified, shall be measured horizontally.
Animal feedlot means a lot or building or combination of lots and buildings intended for the confined feeding, breeding, raising or holding of animals and specifically designed as a confinement area in which manure may accumulate, or where the concentration of animals is such that a vegetative cover cannot be maintained within the enclosure. For purposes of this Code, open lots used for the feeding and rearing of poultry (poultry ranges) shall be considered as animal feedlots. Pastures shall not be considered as animal feedlots when the area enclosed as pasture is equal to or greater than 1.0 acre per animal unit.
Bluff means a topographic feature, such as a hill, cliff or embankment, having the following characteristics (an area with an average slope of less than 18 percent over a distance of 50 feet or more shall not be considered part of the bluff):
(1)
Part or all of the feature is located in a shoreland area;
(2)
The slope rises at least 25 feet above the ordinary high-water level of the water body;
(3)
The grade of the slope from the toe of the bluff to a point 25 feet or more above the ordinary high-water level averages 30 percent or greater; and
(4)
The slope must drain toward the water body.
Bluff impact zone means a bluff and land located within 20 feet from the top of a bluff.
Bluff, toe of the, means the lower point of the lowest 50-foot segment with an average slope exceeding 18 percent. If the lowest such point is lakeward of the OHWL, the OHWL will be defined as the toe.
Bluff, top of the, means that point on the cross section of a bluff below which the slope becomes more than 18 percent and above which the average slope for a distance of 50 feet or more is 18 percent or less.
Commercial use means the principal use of the land and/or buildings for the sale, lease, rental or trade of products, goods and services.
Deck means a horizontal, unenclosed platform with or without attached railings, seats, trellises or other features, attached or functionally related to a principal use or site.

Intensive vegetation clearing means the complete removal of trees or shrubs in a contiguous patch, strip, row or block.
Ordinary high-water level (OHWL) means the boundary of public waters and wetlands, and shall be an elevation delineating the highest water level which has been maintained for a sufficient period of time to leave evidence upon the landscape, commonly that point where the natural vegetation changes from predominantly aquatic to predominantly terrestrial. For watercourses, the ordinary high-water level is the elevation of the top of the bank of the channel. For reservoirs and flowages, the ordinary high-water level is the operating elevation of the normal summer pool. The designated OHWL has been determined by the state department of natural resources for certain water bodies as shown in section 6.12.5970.
Planned unit development (PUD) means a type of development characterized by a unified site design for a number of residential dwelling units or nonresidential sites on a parcel, whether for sale, rent or lease, often involving clustering of units or sites to provide areas of common open space or a mixture of structure types and land uses. Two types of PUD are provided for in this chapter:
(1)
Planned residential development (PRD), in which the nature of allowed uses is nontransient residential, including attached and detached single-family or multiple-family dwellings, subject to the limitations provided for in each zoning district.
(2)
Planned unit development (PUD), Highway 12 Corridor, in which the nature of allowed uses may include residential, commercial, institutional, public and semipublic uses as set forth in the city's comprehensive plan amendment No. 2, and it is limited to areas within the Highway 12 Corridor as defined in that amendment. The Highway 12 PUD offers a mixture of land uses, housing types and densities.
Note: No properties which could be developed via the Highway 12 PUD are within the shoreland overlay district.
Public use means the use of land by the general public or by a public agency on behalf of the general public, for any purpose.
Public waters means any waters as defined in Minn. Stats. § 103G.005, subds. 15 and 16.

Sewage treatment system means septic tanks and a soil absorption system or other type of on-site sewage treatment system as described in chapter 5.24, article II.
Sewerage system means pipelines or conduits, pumping stations and force main, and all other construction, devices, appliances, or appurtenances used for conducting sewage or industrial waste or other wastes to a point of ultimate disposal.
Shore impact zone means land located between the ordinary high-water level of a public water and a line parallel to it at a setback of 50 percent of the structure setback.
Shore setback zone means land located between the ordinary high-water level of a public water and a line parallel to it at the structure setback.
Shoreland means land located within 1,000 feet from the ordinary high-water level of a lake, pond or flowage and 300 feet from a river or stream, or the landward extent of a floodplain designated by ordinance on a river or stream, whichever is greater. Where topographic divides occur at lesser distances from the involved water, the limits of shoreland have been modified per the official map entitled "Shoreland Overlay District," on file at the city offices.
Significant historic site means 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 Minn. Stats. § 307.08. An 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 state archaeologist or the director of the state historical society. All unplatted cemeteries are automatically considered to be significant historic sites.
Steep slope means lands having average slopes of 12 percent or greater as measured over horizontal distances of 50 feet or more, that are not bluffs.
Surface water-oriented commercial use means the use of land for commercial purposes, where access to and use of a surface water feature is an integral part of the normal conductance of business.
Variance means the same as that term is defined or described in Minn. Stats. ch. 462.
Water-oriented accessory structure or facility means a small, aboveground building or other improvement, except stairways, fences, docks 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, lock boxes, and detached decks.
Wetlands shall have the same meaning as the term "protected wetlands" in section 6.12.8110.
(Code 2003, § 78-1211; Ord. No. 101(2nd series), § 1(10.56(3)), 2-24-1992; Ord. No. 126(2nd series), § 1, 4-25-1994; Ord. No. 127(2nd series), §§ 2—4, 7-11-1994; Ord.

The purpose of this article is to promote the public health, safety and general welfare by providing for the wise subdivision, use and development of shorelands abutting public waters that exist within the city's corporate boundaries. The city recognizes that the uncontrolled use and development of shorelands has a negative impact on not only the quality of surface waters, but on the economic, recreational and natural environmental values of shorelands and the waters they surround. The specific intent of this article is to:
(1)
Protect the water quality of Lake Minnetonka and other lakes within the city by allowing development of uses in the shoreland areas which are compatible with the city's comprehensive land use management plan.
(2)
Provide appropriate standards for development which will minimize the impact of shoreland development on the water quality and the economic, aesthetic and natural environment values of the city's lakes.
(Code 2003, § 78-1212; Ord. No. 101(2nd series), § 1(10.56(1)), 2-24-1992)

(Code 2003, § 78-1215; Ord. No. 101(2nd series), § 1(10.56(4)), 2-24-1992)
The use of any shoreland of public waters; the size and shape of lots; the use, size, type and location of structures on lots; the installation and maintenance of water supply and waste treatment systems, the grading and filling of any shoreland areas; the cutting of shoreland vegetation; and the subdivision of land shall be in full compliance with the terms of this article and other applicable regulations.
(Code 2003, § 78-1216; Ord. No. 101(2nd series), § 1(10.56(5)), 2-24-1992)
The public waters of the city have been classified below consistent with the criteria found in Minn. Stats. § 6120.3300, and the protected waters inventory map for the county:
(Code 2003, § 78-1217; Ord. No. 101(2nd series), § 1(10.56(7)), 2-24-1992; Ord. No. 127(2nd series), § 5, 7-11-1994)
The SD Shoreland Overlay District is defined and established to include the following lands within the city:
(1)
All lands within 1,000 feet of the ordinary high-water level of the lakes classified natural environment, recreational development, and general development in section 6.12.5970. The shoreland overlay district includes lands within the city that are located within 1,000 feet of lakes located in adjacent cities, namely Hadley Lake in the City of Plymouth and Wolsfeld Lake in the City of Medina.
(2)
All lands within 300 feet of the ordinary high-water level of the watercourses classified as tributary streams in section 6.12.5970. Where the floodplain of the tributary streams as defined in article VIII of this chapter or as defined elsewhere in this chapter extends further than 300 feet from the ordinary high-water level, the boundary of the shoreland overlay district shall be extended to include those areas designated as floodplain.
(Code 2003, § 78-1218; Ord. No. 101(2nd series), § 1(10.56(8)), 2-24-1992)
The official map of the shoreland overlay district is adopted. A copy of the map shall be kept on file at all times with the city clerk. In their interpretation and application, the provisions of this article shall be held to be minimum requirements and shall be liberally construed in favor of the city and shall not be deemed a limitation or repeal of any other powers granted by state statutes. The boundaries of the shoreland overlay district shall be determined by scaling distances on the official map. Where interpretation is needed as to the exact location of the boundaries of the district as shown on the official map, the city engineer shall make necessary interpretation based on the ordinary high-water level. The person contesting the location of the district boundary shall be given a reasonable opportunity to present his case to the city and to submit technical evidence if he so desires.

(a)
Land suitability. Each lot created through subdivision, including planned unit developments or planned residential developments authorized elsewhere in the zoning and platting codes, must be suitable in its natural state for the proposed use with minimal alteration. In analyzing the suitability of land for a specific use, the city shall consider:
(1)
Susceptibility to flooding;
(2)
Existence of wetlands;
(3)
Soil and rock formations with severe limitations for development;

(10)
Any other feature of the natural land likely to be harmful to the health, safety or welfare of future residents of the proposed subdivision or of the community.
(b)
Consistency with other controls. Subdivisions shall conform to all official controls of the city. Subdivision will not be approved where a later variance from one or more standards in the official controls would be needed to use the lots for their intended purpose. In areas not served by publicly owned sewer and water systems, a subdivision will not be approved unless adequate and conforming water supply and sewage treatment systems can be provided for each lot in conformance with chapter 5.24, article II. Each lot shall meet the minimum lot size and dimensional requirements set forth elsewhere in this Code, including at least a minimum contiguous lawn area, that is free of limiting factors sufficient for the construction of two standard soil treatment systems. Lots that would require use of holding tanks must not be approved.
(c)
Information requirements. Sufficient information must be submitted by the applicant for the city to make a determination of land suitability. In addition to information required by other provisions in this chapter and chapter 6.20, the following information shall also be submitted:
(1)
Topographic contours at two-foot intervals showing limiting site characteristics.
(2)
The surface water features required in Minn. Stats. § 505.02, subd. 1, to be shown on plats, obtained from United States Geological Survey quadrangle topographic maps or more accurate sources.
(3)
Adequate soils information to determine suitability for building and on-site sewage treatment capabilities for every lot from the most current existing sources or from field investigations, such as soil borings, percolation tests or other methods.
(4)
Information regarding adequacy of domestic water supply; extent of anticipated vegetation and topographic alterations; near-shore aquatic conditions, including depths, types of bottom sediments, and aquatic vegetation; and proposed methods for controlling storm water runoff and erosion, both during and after construction activities.
(5)
Location of 100-year floodplain areas and floodway districts from existing adopted maps or data.
(6)
A line or contour representing the ordinary high-water level, the toe and the top of bluffs, and the minimum building setback distances from the top of the bluff and the lake or stream.
(d)
Dedications. When a land or easement dedication is a condition of subdivision approval, the approval must provide easements over natural drainage or ponding areas for management of stormwater and significant wetlands, as regulated in article VIII of this chapter.
(e)
Lakeshore access lots. Lots intended as accesses to public waters or as recreational areas for use by owners of nonriparian lots within a subdivision must meet or exceed the minimum standards set forth in this section.
(Ord. No. 101(2nd series), § 1(10.56(18)), 2-24-1992)
For properties which as a result of the designation of the OHWL are found to abut the boundary of a lake, stream or tributary, no section of this chapter shall be construed as obligating the city to approve variances to provisions of this chapter prohibiting physical improvements, structures or land alteration within protected wetlands, floodplain areas or shorelands. Nothing in this chapter shall be considered as establishing or increasing riparian rights. This article is intended to regulate land use and establish building and zoning restrictions only.
(Code 2003, § 78-1221; Ord. No. 101(2nd series), § 1(10.56(20)), 2-24-1992)
The zoning administrator is responsible for the administration and enforcement of this article. Any violation of the provisions of this article or failure to comply with any of its requirements (including violations of conditions and safeguards established in connection with grants of variances or conditional uses) shall constitute a misdemeanor and shall be punishable as defined by law. Violations of this article can occur regardless of whether or not a permit is required for a regulated activity pursuant to section 6.12.6120.
(Code 2003, § 78-1246; Ord. No. 101(2nd series), § 1(10.56(6)), 2-24-1992)

(1)
Construction on nonconforming lots of record. Development or use of existing lots of record shall be regulated as set forth in section 6.12.320.
(2)
Additions/expansions to nonconforming structures. All additions or expansions to the outside dimensions of an existing nonconforming structure must meet the setback, height, and other requirements set forth in this chapter. Any deviation from these requirements must be authorized by a variance pursuant to provisions of this chapter.
(3)
Nonconforming sewage treatment systems. A nonconforming sewage treatment system (also defined as a noncompliant system) located within the shoreland overlay district must be upgraded and made conforming, at a minimum, at any time a permit or variance of any type is required for any improvement on, or use of, the property, except that systems which are noncompliant due solely to lack of three feet of unsaturated soil or sand between the distribution device and the limiting soil characteristics shall have seven years in which to become compliant per the provisions of chapter 5.24, article II. All other noncompliant sewage treatment system provisions of chapter 5.24, article II shall apply to all shoreland areas.
(Code 2003, § 78-1252; Ord. No. 101(2nd series), § 1(10.16(17)), 2-24-1992; Ord. No. 162(2nd series), § 1, 9-22-1997; Ord. No. 243(3rd series), § 2, 4-13-2020)

Lots intended as accesses to public waters or as recreation areas for use by owners of nonriparian lots within subdivisions are permissible and must meet the following minimum standards:
(1)
Any such lakeshore access lot shall be designated as an outlot and shall not be considered as a buildable residential lot.
(2)
Such an outlot shall not be subject to minimum lot area or width standards, except that the number of inland nonriparian lots which may gain access via such outlot shall not exceed the number obtained by dividing the outlot width measured at the shoreline by the required zoning district lot width, rounded down to the nearest whole number.
(3)
Such outlot shall be jointly owned by all owners of nonriparian lots in the subdivision who are provided riparian access rights on the access outlot.
(4)
No such access outlot shall be created as part of a subdivision plat except when the building lots within the subdivision are separated by an existing public or private roadway from the lakeshore, and the land on either side of the roadway was in common ownership as of the effective date of Ordinance No. 101, adopted February 24, 1992.
(5)
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. The activities may include watercraft launching, loading, storage, beaching, mooring or docking. They can 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 watercraft 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. Such covenants are subject to city approval.
(Code 2003, § 78-1278; Ord. No. 101(2nd series), § 1(10.56(16)(B)), 2-24-1992)

(1)
Building, structure, and on-site sewerage system setbacks (in feet) from ordinary high-water level.
(2)
Additional building and structure setbacks. The following additional setbacks apply, regardless of the classification of the water body:
1 Except for accessory buildings on lakeshore lots as regulated in this chapter and except for buildings and structures subject to less restrictive side yard adjacent to street setbacks as regulated in the various zoning districts.
(3)
Bluff impact zones. Buildings, structures and accessory facilities, except stairways, landings and lock boxes, must not be placed within bluff impact zones.
(4)
Uses without water-oriented needs. 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.
(5)
Fences, docks, retaining walls. No fence shall be placed within the shore setback zone. Portions of dock located landward of the OHWL shall be considered as a landing, subject to the regulations for landings per section 6.12.6270. Retaining walls within the shore setback zone may be permitted according to the following:
a.
A retaining wall may be constructed within the shore setback zone if it is an integral part of a permitted lake access stair and the retaining wall is designed to be the minimum size necessary.
b.
A replacement retaining wall, including a change in material, may be permitted within the shore setback zone when all of the following conditions are met:
1.
The wall is under four feet in height, and in the same location; and
2.
The existing wall shows signs of failure.

Shore setback zone and bluff impact zone deficiencies must be evaluated, and reasonable improvements be made as part of the conversion. These improvements must include, where applicable, the following:
a.
Removal of extraneous buildings, docks or other facilities that no longer need to be located in shore setback zone or bluff impact zone.
b.
Remedial measures to correct erosion sites and improve vegetative cover and screening of buildings and other facilities as viewed from the water.
c.
If existing dwelling units are located in the shore setback zone or bluff impact zone, conditions shall be attached to approvals of conversions that preclude exterior expansions in any dimension or substantial alterations. The conditions must also provide for future relocation of dwelling units, where feasible, to other locations, meeting all setback and alteration requirements when they are rebuilt or replaced.
(4)
Existing dwelling unit or dwelling site densities that exceed the standards in section 6.12.6560 may be allowed to continue but must not be allowed to be increased, either at the time of conversion or in the future. Efforts must be made during the conversion to limit impacts of high densities by requiring seasonal use, improving vegetative screening, centralizing shore recreation facilities, installing new sewage treatment systems, or other means.

The purpose of this article is to promote the public health, safety and general welfare by providing for the wise subdivision, use and development of shorelands abutting public waters that exist within the city's corporate boundaries. The city recognizes that the uncontrolled use and development of shorelands has a negative impact on not only the quality of surface waters, but on the economic, recreational and natural environmental values of shorelands and the waters they surround. The specific intent of this article is to:
(1)
Protect the water quality of Lake Minnetonka and other lakes within the city by allowing development of uses in the shoreland areas which are compatible with the city's comprehensive land use management plan.
(2)
Provide appropriate standards for development which will minimize the impact of shoreland development on the water quality and the economic, aesthetic and natural environment values of the city's lakes.

(1)
Any such lakeshore access lot shall be designated as an outlot and shall not be considered as a buildable residential lot.
(2)
Such an outlot shall not be subject to minimum lot area or width standards, except that the number of inland nonriparian lots which may gain access via such outlot shall not exceed the number obtained by dividing the outlot width measured at the shoreline by the required zoning district lot width, rounded down to the nearest whole number.
(3)
Such outlot shall be jointly owned by all owners of nonriparian lots in the subdivision who are provided riparian access rights on the access outlot.
(4)
No such access outlot shall be created as part of a subdivision plat except when the building lots within the subdivision are separated by an existing public or private roadway from the lakeshore, and the land on either side of the roadway was in common ownership as of the effective date of Ordinance No. 101, adopted February 24, 1992.
(5)
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. The activities may include watercraft launching, loading, storage, beaching, mooring or docking. They can 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 watercraft 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. Such covenants are subject to city approval.

Evaluation of suitability must include consideration of land slope, water depth, vegetation, soils, depth to groundwater and bedrock or other relevant factors. The number of dwelling units or sites which may be granted lake access shall not exceed the number of riparian dwelling units or sites which could be created under a standard subdivision. The allowable number of dock slips or moorings and the designation of which dwelling units or sites shall have the right to use those slips or moorings shall be subject to council approval and shall be defined in the covenants governing the PRD. In no case shall the number of slips or moorings exceed the number allowed under the official controls of the Lake Minnetonka Conservation District. All docks serving three or more dwelling units shall be subject to the joint use dock licensing requirements in chapter 6.28, article II.
(4)
Structures. Parking areas and other facilities 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 city, assuming summer, leaf-on conditions. Vegetative and topographic screening must be preserved, if existing, or may be required to be provided.
(5)
Accessory structures and facilities must meet the required principal structure setback and must be centralized, except for those pedestrian access and equipment storage structures allowed elsewhere in this chapter.

Existing resorts or other land uses may be converted to planned residential developments if all of the following standards are met:
(1)
Proposed conversions must be initially evaluated using the same procedures for PRDs involving all new construction. Inconsistencies between existing features of the development and these standards must be identified.
(2)
Deficiencies involving water supply and sewage treatment, impervious coverage, open space, and shore recreation facilities must be corrected as part of the conversion or as specified in the conditional use permit.
(3)
Shore setback zone and bluff impact zone deficiencies must be evaluated, and reasonable improvements be made as part of the conversion. These improvements must include, where applicable, the following:
a.
Removal of extraneous buildings, docks or other facilities that no longer need to be located in shore setback zone or bluff impact zone.
b.
Remedial measures to correct erosion sites and improve vegetative cover and screening of buildings and other facilities as viewed from the water.
c.
If existing dwelling units are located in the shore setback zone or bluff impact zone, conditions shall be attached to approvals of conversions that preclude exterior expansions in any dimension or substantial alterations. The conditions must also provide for future relocation of dwelling units, where feasible, to other locations, meeting all setback and alteration requirements when they are rebuilt or replaced.
(4)
Existing dwelling unit or dwelling site densities that exceed the standards in section 6.12.6560 may be allowed to continue but must not be allowed to be increased, either at the time of conversion or in the future. Efforts must be made during the conversion to limit impacts of high densities by requiring seasonal use, improving vegetative screening, centralizing shore recreation facilities, installing new sewage treatment systems, or other means.
