SHORELAND MA.NAGEMENT* <br /> <br />Page 9 of21 <br /> <br />ordinary high-water level shall be as follows: <br /> <br />TABI.R TNSF~T' <br /> <br /> Structures <br /> Sewage <br />Classes of Public Waters Unsewered Sewered Treatment <br />(feet) (feet) System <br /> (feet) <br />Lakes: <br />Natural environment 150 150 150 <br />General development 75 50 50 <br />Rivers: <br />Urban and tributary 100 50 75 <br /> <br />One water-oriented accessory structure designed in accordance with subsection (b) of this section may be set <br />back a minimum distance often feet from the ordinary high-water level. <br />(2) Additional structure setbacks. The following additional structure setbacks apply, regardless of the . <br />classification of the water body: <br />a. Setback from top of bluff: 30 feet. <br />b. Setback from unplatted cemetery; 50 feet. <br />(3) Bluffimpact zones. Structures and accessory facilities, except stairways and landings, shall not be placed <br />within bluff impact zones. <br />(4) Uses without water-oriented needs. Commercial, industrial, public and semipublic uses without water- <br />oriented needs shall be located on lots or parcels without public waters frontage Of, if located on lots or <br />parcels with public waters frontage, shall either be set back double the normal ordinary high-water level <br />setback or be substantially screened from view from the water by vegetation or topography, assuming <br />summer, leaf-on conditions. <br />(b ) Design criteria for structures. <br />(1) Flood protectioll elevatiol1s. Structures shall be placed in accordance \\i'ith any floodplain regulations <br />applicable to the site. Where these controls do not exist, the elevation to which the lowest floor, including <br />basement, is placed or floodproofed shall be determined as follows: <br />a. For lakes, the elevation shall be detemrined by placing the lowest floor at a level at least three feet above <br />the highest known water level, or three feet above the ordinary high-water level, whichever is higher. <br />b. For rivers and streams, the elevation shall be determined by placing the lowest floor at least three feet <br />above the highest known water level. <br />c. Water-oriented accessory structures may have the lowest floor placed lower than the elevation determined <br />pursuant to this subsection (b)(1) if the structure is constructed of flood resistant materials to the elevation, <br />electrical and mechanical equipment is placed above the elevation and, if long duration flooding is anticipated, <br />the ~tructure is hllilt to withstand ice action and wind-driven wave~ and dehri~. <br />(2) Water-oriented accessory structures. Each lot may have one ,vater-oriented accessory structure not <br />meeting the normal structure setback in subsection (a) of this section if this water-oriented accessory structure <br />complies with the following provisions: <br />a. The structure or facility shall not exceed ten feet in height, exclusive of safety rails, and cannot occupy an <br />area greater than 250 square feet. Detached decks shall not exceed eight feet above grade at any point. <br />b. The setback of the structure or facility from the ordinary high-water level shall be at least ten feet. <br />c. The structure or facility shall be treated to reduce visibility as viewed from public ,vaters and adjacent <br />shorelands by 'vegetation, topography, increased setbacks or color, assuming summer, leaf-on conditions. <br />d. The roof may be used as a deck \\lith safety rails, but shall not be enclosed or used as a storage area. <br /> <br />http://library4 . muni code. com/mcc/Doc Vi ew/13 427/1/66/84/96 <br /> <br />5/9/2006 <br />
