1 1. The structure or facility must not exceed ten feet in height, exclusive of safety rails, 2 and cannot occupy an area greater than 250 square feet. Detached decks must not 3 exceed eight feet above grade at any point; 4 2. The setback of the structure or facility from the ordinary high water level must be 5 at least ten feet; 6 3. The structure or facility must be treated to reduce visibility as viewed from public 7 waters and adjacent shorelands by vegetation, topography, increased setbacks or 8 color, assuming summer, leaf -on conditions; 9 4. The roof may be used as a deck with safety rails, but must not be enclosed or used 10 as a storage area; 11 5. The structure or facility must not be designed or used for human habitation and 12 must not contain water supply or sewage treatment facilities; and 13 6. As an alternative for general development and recreational development 14 waterbodies, water -oriented accessory structures used solely for watercraft 15 storage, and including storage of related boating and water -oriented sporting 16 equipment, may occupy an area up to 400 square feet provided the maximum width 17 of the structure is 20 feet as measured parallel to the configuration of the shoreline. 18 c. Stairways, lifts, and landings. Stairways and lifts are the preferred alternative to major 19 topographic alterations for achieving access up and down bluffs and steep slopes to shore 20 areas. Stairways and lifts must meet the following design requirements: 21 1. Stairways and lifts must not exceed four feet in width on residential lots. Wider 22 stairways may be used for commercial properties, public open -space recreational 23 properties, and planned unit developments; 24 2. Landings for stairways and lifts on residential lots must not exceed 32 square feet 25 in area. Landings larger than 32 square feet may be used for commercial properties, 26 public open -space recreational properties, and planned unit developments; 27 3. Canopies or roofs are not allowed on stairways, lifts, or landings; 28 4. Stairways, lifts, and landings may be either constructed above the ground on posts 29 or pilings, or placed into the ground, provided they are designed and built in a 30 manner that ensures control of soil erosion; 31 5. Stairways, lifts, and landings must be located in the most visually inconspicuous 32 portions of lots, as viewed from the surface of the public water assuming summer, 33 leaf -on conditions, whenever practical; and 34 6. Facilities such as ramps, lifts, or mobility paths for physically handicapped persons 35 are also allowed for achieving access to shore areas, provided that the dimensional 36 and performance standards of the items in subsections (f)(2)c.1 to 5 of this section 37 are complied with in addition to the requirements of Minn. Rules ch. 1340. 38 d. Significant historic sites. No structure may be placed on a significant historic site in a 39 manner that affects the values of the site unless adequate infoiniation about the site has 40 been removed and documented in a public repository. 41 e. Steep slopes. The city engineer must evaluate possible soil erosion impacts and 42 development visibility from public waters before issuing a permit for construction of 43 sewage treatment systems, roads, driveways, structures, or other improvements on steep 44 slopes. When determined necessary, conditions must be attached to issued permits to 45 prevent erosion and to preserve existing vegetation screening of structures, vehicles, and 46 other facilities as viewed from the surface of public waters, assuming summer, leaf -on 47 vegetation. 48 (3) Height of structures. All structures in residential districts, except churches and nonresidential 49 agricultural structures, must not exceed 35 feet in height. 50 (D) Shoreland alterations. Alterations of vegetation and topography will be regulated to prevent erosion 51 into public waters, fix nutrients, preserve shoreland aesthetics, preserve historic values, prevent bank 52 slumping, and protect fish and wildlife habitat.
