Stairways, lifts, and landings. Stairways and lifts are the preferred alternative to major 8 topographic alterations for achieving access up and down bluffs and steep slopes to 9 shore areas. Stairways and lifts must meet the following design requirements: 10 1. Stairways and lifts must not exceed four feet in width on residential lots. Wider 11 stairways may be used for commercial properties,public open-space recreational 12 properties, and planned unit developments; 13 2. Landings for stairways and lifts on residential lots must not exceed 32 square feet 14 in area. Landings larger than 32 square feet may be used for commercial 15 properties, public open-space recreational properties, and planned unit 16 developments; 17 3. Canopies or roofs are not allowed on stairways, lifts, or landings; 18 4. Stairways, lifts, and landings may be either constructed above the ground on 19 posts or pilings, or placed into the ground, provided they are designed and built 20 in a manner that ensures control of soil erosion; 21 5. Stairways, lifts, and landings must be located in the most visually inconspicuous 22 portions of lots,as viewed from the surface of the public water assuming summer, 23 leaf-on conditions,whenever practical; and 24 6. Facilities such as ramps,lifts,or mobility paths for physically handicapped persons 25 are also allowed for achieving access to shore areas, provided that the 26 dimensional and performance standards of the items in subsections (f)(2)c.1 to 5 27 of this section are complied with in addition to the requirements of Minn.

No structure may be placed on a significant historic site in a 30 manner that affects the values of the site unless adequate information about the site 31 has been removed and documented in a public repository. 32 e. Steep slopes. The city engineer must evaluate possible soil erosion impacts and 33 development visibility from public waters before issuing a permit for construction of 34 sewage treatment systems, roads, driveways, structures, or other improvements on 35 steep slopes. When determined necessary, conditions must be attached to issued 36 permits to prevent erosion and to preserve existing vegetation screening of structures, 37 vehicles, and other facilities as viewed from the surface of public waters, assuming 38 summer, leaf-on vegetation. 39 (3) Height of structures. All structures in residential districts, except churches and nonresidential 40 agricultural structures, must not exceed 35 feet in height. 41 (D) Shoreland alterations.Alterations of vegetation and topography will be regulated to prevent erosion 42 into public waters, fix nutrients, preserve shoreland aesthetics, preserve historic values, prevent 43 bank slumping,and protect fish and wildlife habitat. 44 (1) Vegetation alterations. 45 a. Vegetation alteration necessary for the construction of structures and sewage 46 treatment systems and the construction of roads and parking areas regulated by this 47 subdivision are exempt from the vegetation alteration standards that follow. 48 b.
