91-023 ORD . . . CITY OF ELK RIVER SUMMARY OF SHORELAND MANAGEMENT ORDINANCE ORDINANCE 91-23 RESOLUTION 91- 69 A RESOLUTION APPROVING NOTICE OF PUBLICATION OF ORDINANCE 91-23 The City Council of the City of Elk River hereby amends Section 904 of the Elk River Code of Ordinances titled "Shoreland Management Ordinance" and does ordain as follows: The City of Elk River has adopted a Shoreland Management Ordinance replacing the Shore land Management regulations previously contained in the Elk River Zoning Ordinance. The Shore land Management Ordinance regulates development of property within the shore land district which is defined as property within 1,000 ft. of the ordinary high water level of a DNR Protected lake, pond or flowage and 300 ft. from a river or stream or the landward extent of the des igna ted floodplain, whichever is greater. The Shore land Management Ordinahce adopts a shore land class if ication system for identifying protected water bodies. The ordinance also adopts setbacks for structures and sewage treatment systems as well as lot size and width standards within the shoreland district. The Shore land Management Ordinance adopts the Minnesota Pollution Control Agency's Individual Sewage Treatment System Standards Chapter 7080 and sets forth standards and procedures for dealing with nonconforming septic systems. This ordinance also gives the City of Elk River the authority to review Planned Unit Development proposals and sets forth procedures and criteria which must be followed in reviewing such requests. The ordinance designates the Zoning Administrator as the official responsible to administer and enforce the Shoreland Hanagement Ordinance. This ordinance requires a permi t before shoreland alterations, placement of fill, or excavation can be done within the shore land district and sets forth procedures and requirements for obtaining such permits. Standards are also set forth for mineral excavation, forestry and agricultural uses. The ordinance further establishes standards and procedures for obtaining variances and conditional use permits within the shore land district. The ordinance also regulates nonconforming uses and nonconforming legal lots of record within the shoreland district and establishes penalties for violations of the Shore 1 and Management Ordinance. A copy of the full text of the Shore land Management Ordinance is available for inspection by any person at the office of the Elk River City Clerk during normal business hours. . . . Ordinance passed and adopted the 18th day of November I 1991. This resolution of notice of publication passed and adopted this 25th day of November, 1991.

Statement of Purpose - The uncontrolled use of shore lands of the City of Elk River, Minnesota affects the public health, safety and general welfare not only by contributing to pollution of public waters, but also by impairing the local tax base. Therefore, it is in the best interests of the public health, safety and welfare to provide for the wise subdivision, use and development of shore lands of public waters. The Legislature of Minnesota has delegated responsibility to local governments of the state to regulate the subdivision, use and development of the shore lands of public waters and thus preserve and enhance the quality of surface waters, conserve the economic and natural environmental values of shorelands, and provide for the wise use of waters and related land resources. This responsibility is hereby recognized by the City of Elk River. 904.02 - GENERAL PROVISIONS AND DEFINITIONS 1. Jurisdiction - The provisions of this Ordinance shall apply to the shore lands of the pUblic water bodies as defined in Section 904.02(7) and as classified in Section 904.06 of this Ordinance. Pursuant to Minnesota Regulations, Parts 6120.2500 - 6120.3900, no lake, pond, or flowage less than 10 acres in size in municipalities need be regulated in a local government's shoreland regulations. A body of water created by a private user where there was no previous shore land may, at the discretion of the governing body, be exempt from this Ordinance. 2. Compliance - The use of any shore land 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 area; the cutting of shore 1 and vegetation; and the subdivision of land shall be in full compliance with the terms of this Ordinance and other applicable regulations. 3. Enforcement - The City of Elk River is responsible for the administration and enforcement of this Ordinance. Any violation of the provisions of this Ordinance 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 outlined in Section 900.46 and as defined by Minnesota Rules and Statutes. Violations of this Ordinance can occur regardless of whether or 9.146 . . . not a permit is required for a regulated activity pursuant to Section 904.04(1) of this Ordinance. 4. Interpretation - In their interpretation and application, the provisions of this Ordinance shall be held to be minimum requirements and shall be liberally construed in favor of the governing body and shall not be deemed a limitation or repeal of any other powers granted by State Statutes. 5. Severability - If any section, clause, provision, or portion of this Ordinance is adjudged unconstitutional or invalid by a court of competent jurisdiction, the remainder of this Ordinance shall not be affected thereby. 6. Abroqation and Greater Restrictions- It is not intended by this Ordinance to repeal, abrogate, or impair any existing easements, covenants, or deed restrictions.

Residential subdivisions with dwelling unit densities exceeding those in the tables in Section 904.08(1) may only be allowed if designed and approved as residential planned unit developments under Section 904.14 of this Ordinance and Section 900.12 of the Zoning Ordinance. Only land above the ordinary high water, level of public waters may be used to meet lot area standards, and lot width standards shall be met at both the ordinary high water level and at the building line. The sewered lot area dimensions in Section 904.08(1) may only be used if publicly owned sewer system is available to the property. . ii. Lots intended as controlled accesses to public waters or as recreation areas for use by only the owners of nonriparian lots within subdivisions are 9.156 . permissible and shall meet or exceed the following standards: (1) lots shall meet the width and size requirements for residential lots, and be suitable for the intended uses of controlled access lots. (2) If docking, mooring, or over-water storage of more than six (6) watercraft is to be allowed at a controlled access lot, then the width of the lot (keeping the same lot depth) shall be increased by the percent of the requirements for riparian residential lots for each watercraft 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 100 100-200 201-300 301-400 Greater than 400 25 20 15 10 5 (3) Lots shall 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; and . (4) Recorded covenants or other equally effective legal instruments 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 shall 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 shall 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 shall require centralization of all common facilities and activities in the most suitable locations on the lot to minimize topographic and vegetation alterations. They shall also require all parking 9.157 . . . 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. 2. Placement, Design, and Heiqht of Structures. a. Placement of Structures on Lots. When more than one setback applies to a site, structures and facilities shall be located to meet all setbacks. 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 from the ordinary high water level, provided the proposed building site is not located in a shore impact zone or in a bluff impact zone. Structures shall be located as follows: i. Structure and On-site Sewage System Setbacks (in feet) from Ordinary High Water Level Setbacks * Classes of Public Structures Waters Unsewered Sewered Sewage Treatment System Lakes Natural Environment 150' 150' 150' General Development 75' 50' 50' Rivers Urban and Tributary 100' 50' 75' * One water-oriented accessory structure designed in accordance with Section 904.08(2)(b) of this Ordinance may be set back a minimum distance of ten (10) feet from the ordinary high water level. 11. Additional Structure Setbacks. The following additional structure setbacks apply, regardless of the classification of the waterbody: Setback From: Setback (in feet) (1) top of bluff; (2) unplatted cemeterYi 30' 50' iii. Bluff Impact Zones. Structures and accessory facilities, except stairways and landings, shall not 9.158 . . . be placed within bluff impact zones. iv. Uses Without Water-oriented Needs. Commercial, industrial, public and semi-public uses without water-oriented needs shall be located on lots or parcels without public waters frontage, or, if located on lots or parcels with public waters frontage, shall 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. Design Criteria For Structures. i. High Water Elevations. Structures shall be placed in accordance with any floodplain regulations applicable to the site. Where these controls do not exist, the elevation to which the lowest floor, including basement, is placed or flood-proofed shall 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; (2) for rivers and streams, by placing the lowest floor at least three feet above the highest known water level. (3) water-oriented accessory structures may have the lowest floor placed lower than the elevation determined in this item if the structure is constructed of flood-resistent 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. ii. Water-oriented Accessory Structures. Each lot may have one water-oriented accessory structure not meeting the normal structure setback in Section 904.08(2)(a) of this Ordinance if this water-oriented accessory structure complies with the following provisions: (1) the structure or facility shall not exceed ten feet in height, exclusive of safety rails, and cannot occupy an area greater than 250 square feet. Detached decks shall not exceed eight feet above grade at any point. (2) the setback of the structure or facility from the ordinary high water level shall be at least ten feet; 9.159 . (3) the structure or facility shall be treated to reduce visibility as viewed from public waters and adjacent shore lands by vegetation, topography, increased setbacks or color, assuming summer, leaf-on conditions; (4) the roof may be used as a deck with safety rails, but shall not be enclosed or used as a storage area; (5) the structure or facility shall not be designed or used for human habitation and shall not contain water supply or sewage treatment facilities; and (6) as an alternative for general 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. . iii. Performance Standards for Stairways, Lifts, and Landinqs. Stairways and lifts are the preferred alternative to major topographic alterations for achieving access up and down bluffs and steep slopes to shore area. If stairways, and lifts, and landings meet the following design requirements they shall not be considered a water oriented accessory structure, however, they may be required to receive a building permit. (1) stairways and lifts shall 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 shall 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; 9.160 . (5) stairways, lifts, and landings shall 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; and (6) facilities such as ramps, lifts, or mobility paths for physically handicapped persons 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 Minnesota Regulations Chapter 1340. iv. Significant Historic Sites - 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. . v. Steep Slopes - The Building and Zoning Administrator shall 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 necessary, conditions shall 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. c. Height of Structures- All structures in city residential districts, except churches and nonresidential agricultural structures, shall not exceed 30 feet in height. 3. Shoreland Alterations - Alterations of vegetation and topography will be regulated to prevent erosion into public waters, fix nutrients, preserve shore land aesthetics, preserve historic values, prevent bank slumping, and protect fish and wildlife habitat. a. Vegetation Alterations. i.

Divide the area computed in subitem iii. by the average determined in subitem i. This yields a base number of dwelling units and sites for each tier. . v. Determine whether the project is eligible for any additional density increases. To be eligible, projects shall meet all of the design standards in item b below and exceed one or more of them. The City may decide how much, if any, increase in density to allow for each tier, but shall not exceed the maximum allowable density increases listed in the following table: Maximum Allowable Dwelling Unit Or Site Density Increases for Commercial Planned Unit Developments Tier Maximum density increase within each tier (percent) First Second Third Fourth Fifth 50 100 200 200 200 vi. Allowable densities may be transferred from any tier to any other tier further from the shore land lake or river, but shall not be transferred to any other tier closer. . b. The design criteria are: 9.180 . i. Open space. Commercial planned unit developments shall contain open space meeting all of the following criteria: (1) At least 50 percent of the total project area shall be preserved as open space. (2) Dwelling units or sites, road rights-of-way, or land covered by road surfaces, or parking areas, except water-oriented accessory structures or facilities, are developed areas and shall not be included in the computation of open space. (3) Open space shall include areas with physical characteristics unsuitable for development in their natural state, and areas containing significant historic sites or unplatted cemeteries. (4) All shore impact zones within commercial planned unit developments shall be included as open space, and at least 50 percent of these areas shall be preserved in their natural or existing state. . (5) Open space may include outdoor recreation facilities for use by guests staying in dwelling units or sites, or the public. (6) Open space may include subsurface sewage treatment systems if use of the space is restricted to avoid adverse impacts on the systems. ii. Design of sttuctures"and facilities shall be done according to the following standards: (1) Commercial planned unit developments shall be connected to publicly owned water supply and sewer systems, if available. On-site water supply~pd sewage treatment system,s shall be designed 'and installed to meet or' exceed applicable rules of the Minnesota Department of Health and Sections 904.08(2) and 904.08(8) of this Ordinance. On-site sewage treatment systems shall be located on the most suitable areas of the development, and sufficient lawn area free of limiting factors shall be provided for a replacement soil treatment system for each sewage system. . (2) Dwelling units or sites shall be located on suitable areas of the development. They shall be designed and located to meet or exceed the following dimensional standards for the relevant 9.181 . shore land classification: setback from the ordinary high water level, elevation above surface water features, and maximum height. Maximum density increases may only be allowed if structure setbacks from the ordinary high water level are increased to at least 50 percent greater than the minimum setback, or the impact on the waterbody is reduced an equivalent amount through vegetative management, topography or other means acceptable to the City and the setback is at least 25 percent greater than the minimum setback. (3) Structures, parking areas, and other facilities shall be designed and located in a manner that minimizes their visibility from surface water features, assuming summer, leaf-on conditions. The structure, dwelling unit, accessory structure, or parking area shall be treated to reduce visibility as viewed from public waters and adjacent shore lands by vegetation, topography, increased setbacks, color, or other means acceptable to the local unit of government assuming summer, leaf-on conditions. Vegetative and topographic screening shall be preserved, if existing, or may be required to be provided. . (4) Water -oriented accessory structures and facilities may be located within shore impact zones if they meet or exceed design standards contained in Section 904.08(2). (5) Shore recreation facilities, including but not limited to swimming areas, docks, and watercraft mooring areas and launching ramps, shall be centralized and located in areas suitable for them. Evaluation of suitability shall include consideration of land slope, water depth, vegetation, soils, depth to groundwater and bedrock, or other relevant factors. The number of watercraft allowed to be continuously beached, moored, or docked shall not exceed one for each allowable dwelling unit or site in the first tier, notwithstanding existing mooring sites in an existing harbor. Launching ramp facilities, including a small dock for loading and unloading equipment, may be provided for use by occupants of dwelling units or sites located in other tiers. . iii. Erosion control and stormwater management for commerical planned unit developments shall: (1) Be designed, and their construction managed, to minimize the likelihood of serious erosion 9.182 . occurring either during or after construction. This shall be accomplished by limiting the amount and length of time of bare ground exposure. Temporary ground covers, sediment entrapment facilities, vegetated buffer strips, or other appropriate techniques shall be used to minimize erosion impacts on surface water features. Erosion control plans approved by the soil and water conservation district may be required if project size and site physical characteristics warrant. (2) Be designed and constructed to effectively manage reasonably expected quantities and qualities of stormwater runoff. Impervious surface coverage within any tier shall not exceed 25 percent of the tier area, except 35 percent impervious surface coverage may be allowed in the first tier of general development lakes with an approved stormwater management plan and consistency with part 904.08(3). . . 9.183 . . .
