"Significant surface water connection" means a surface water flow that is continuous for thirty days or more during years of normal rainfall. "Steep slopes" means any ground that rises ten feet or more for every twenty-five feet of horizontal distance,thus having a grade of forty percent or steeper.A slope is delineated by establishing its toe and top: 1. "Toe"of a steep slope is the lowermost limit of the area where the ground surface rises ten feet or more vertically within a horizontal distance of twenty-five feet. 2. "Top"of a steep slope is a distinct,sharp break in slope which separates slopes inclined at less than forty percent from slopes equal to or greater than forty percent.Where no distinct break in slope exists,the top of the steep slope shall be the uppermost limit of the area where the ground surface drops ten feet or more vertically within a horizontal distance of twenty-five feet. "Stream" means those areas where naturally occurring surface waters flow sufficiently to produce a defined channel or bed which demonstrates evidence of the passage of water including, but not limited to,bedrock channels,gravel beds,sand and silt beds and defined-channel swales.A"defined channel or bed" means a watercourse that is scoured by water or contains deposits of mineral alluvium.The channel or bed need not contain water during the entire year.Streams do not include watercourses which were created entirely by artificial means,such as irrigation ditches,canals, roadside ditches or storm or surface water run-off features, unless the artificially created watercourse contains salmonids or conveys a stream that was naturally occurring prior to the construction of the artificially created watercourse. "Stream channel bottom" means the submerged portion of the stream cross-section which is totally an aquatic environment.The channel bottom may be seasonally dry. "Stream,Type F"means those streams defined in WAC 122-16-030,Water Typing System, as Type F water. "Stream,Type Np"means those streams defined in WAC 122-16-030,Water Typing System,as Type Np water. "Stream,Type Ns" means those streams defined in WAC 122-16-030,Water Typing System,as Type Ns water. "Stream,Type S" means those streams defined in WAC 122-16-030,Water Typing System,as Type S water. "Swamp"means an area permanently saturated or inundated by water,and occupied predominantly by either a scrub-shrub or forested wetland vegetation community. "Unavoidable and necessary impacts"means impacts to regulated critical areas after the applicant proposing to alter a regulated critical area has demonstrated that no reasonable alternative exists for the proposed project. "Undevelopable area" means: 1. Regulated wetlands; 2. Geologically hazardous areas which are determined by supporting studies to be unsuitable for development; 3. Streams; Ch.19.04 Definitions 27 City Council Action(11/04/2020)
