(A) High water elevations. Structures must be placed in accordance with floodplain regulations applicable to the site.
(B) Water-oriented accessory structures. Each lot may have one water-oriented accessory structure not meeting the normal structure setback if the water-oriented accessory structure complies with all of the following:
(1) The structure or facility may not exceed ten feet in height, exclusive of safety rails, and cannot occupy an area greater than 250 square feet. Detached decks may 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 or color, assuming summer, leaf-on conditions.
(4) The 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 the Blue Lake and U.S. Lock and Dam No. 8 Pool shoreland areas, 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.
(C) Use standards. 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 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. Those with water-oriented needs must meet the following standards:
(1) Uses must be designed to incorporate topographic and vegetative screening of parking areas and structures.
(2) Uses that require short-term watercraft mooring for patrons must centralize such facilities and design them to be of minimum size and in such a manner to avoid obstructions of navigation.
(3) Uses that depend on patrons arriving by watercraft may use signs and lighting to convey needed information providing that no signs are placed in or upon public waters. Signs may be placed within the shore impact zone if they are of minimum size and convey the location and name of the establishment and the general types of goods and services available. Such signs shall comply with the city sign regulations. Lights shall be shielded or directed to prevent illumination out across public waters.
(D) Stairways, lifts and landings. Stairways and lifts are the preferred alternative to major topographic alterations for achieving access up and down bluffs and steep slopes to shore areas. Stairways and lifts on residential lots shall not exceed four feet in width with landings not exceeding 32 square feet in area. Wider stairways may be used for commercial properties and public open space recreational properties. Canopies or roofs are not allowed on stairways, lifts or landings. Stairways, lifts and landings must be located in the most visually inconspicuous portion of the lot and shall be built in a manner that ensures control of soil erosion.
(E) 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 depository.
