Des Moines Shoreline Master Program<br />

Shorelines 1 . All of the water areas of the state, including reservoirs, and their associated<br />

shorelands, together with the lands underlying them; except (i) shorelines of statewide<br />

significance; (ii) shorelines on segments of streams upstream of a point where the mean annual<br />

flow is twenty cubic feet per second or less and the wetlands associated with such upstream<br />

segments; and (iii) shorelines on lakes less than twenty acres in size and wetlands associated<br />

with such small lakes.<br />

Shorelines of Statewide Significance 2 . Those areas of Puget Sound in the City of Des Moines<br />

lying seaward from the line of extreme low tide.<br />

Shor elines of the state 1 . The total of all “shorelines” and “shorelines of statewide significance”<br />

within the City of Des Moines.<br />

Should 1 . Indicates the particular action is required unless there is a demonstrated, compelling<br />

reason, based on policy of the SMA and the Des Moines SMP, against taking the action.<br />

Significant vegetation removal 1 . The removal or alteration of trees, shrubs, and/or ground cover<br />

by clearing, grading, cutting, burning, chemical means, or other activity that causes significant<br />

ecological impacts to functions provided by such vegetation. The removal of invasive or noxious<br />

weeds does not constitute significant vegetation removal. Tree pruning, not including tree<br />

topping where it does not affect ecological functions, does not constitute significant vegetation<br />

removal.<br />

Special environmental study 3 . A technical report prepared by a qualified professional. Special<br />

environmental studies are intended to evaluate past and present environmental conditions of<br />

certain properties, potential environmental impacts associated with certain development<br />

proposals, and as appropriate, recommend mitigation measures that can be expected to lessen the<br />

severity of identified adverse environmental impacts. The content and scope of required special<br />

environmental studies shall be as specified by the community development director.<br />

Stream corridor 3 . A perennial, intermittent, or ephemeral stream including its channel bottom,<br />

lower and upper banks, area beyond the top of the upper bank which influences the stream and is<br />

influenced by the presence of water, and the vegetation inhabiting this area. This area is known<br />

as the “riparian zone” which is an area transitional between aquatic and terrestrial (upland)<br />

ecosystems having distinct vegetation and soil characteristics. Riparian zones are most<br />

commonly recognized by bottomland, flood plain, and streambank vegetation. In developed<br />

watersheds, portions of the stream corridor may currently be in a partially culverted or<br />

channelized condition by artificial conveyance systems.<br />

Streambed 2 . The channel of a river or other watercourse and adjacent land areas that are<br />

inundated with flood waters during a 100-year flood.<br />

Structure 1 . A permanent or temporary edifice or building, or any piece of work artificially built<br />

or composed of parts joined together in some definite manner, whether installed on, above, or<br />

below the surface of the ground or water, except for vessels.<br />
