In any area where the ordinary high water <br /> mark cannot be found,the line of mean high water shall substitute. In braided channels and alluvial <br /> fans,the ordinary high water mark or substitute shall be measured so as to include the entire stream <br /> feature. <br /> "Plant associations of infrequent occurrence" means one or more plant species on a landform type <br /> which, because of the rarity of the habitat or the species involved or both,or for other botanical or <br /> environmental reasons, do not occur frequently in Everett or Snohomish County. <br /> "Pond" means an area permanently inundated by water in excess of six feet deep and less than twenty <br /> acres and larger than two thousand five hundred square feet in area as measured at the ordinary high <br /> water mark. <br /> Protected Area means lands that lie within the boundaries of the floodway and riparian corridor. <br /> "Reasonable use" or"reasonable economic use" means a legal concept that has been articulated by <br /> federal and state courts in regulatory takings cases. <br /> "Restoration" means the return of a stream or wetland,or terrestrial ecosystem to a state in which its <br /> functions and values significantly approach its unaltered state. <br /> "Riparian corridor" means a perennial, intermittent, ephemeral stream or swale including its channel <br /> bottom; lower and upper banks,and area beyond the top of the upper bank which influences the <br /> stream through shading and organic matter input, and is influenced by the presence of water, <br /> particularly in regard to plant composition.The riparian corridor is the transitional area between aquatic <br /> and upland ecosystems and does not necessarily include the entire floodplain of a stream. <br /> "Salmonid" means a member of the fish family Salmonidae. In the city these include chinook,coho, <br /> chum, sockeye and pink salmon; cutthroat, brook, brown, rainbow and steelhead trout; and Dolly <br /> Varden, kokanee and char. <br /> "Seismic hazard areas" means those areas of the city subject to severe risk of earthquake damage as a <br /> result of seismically induced ground shaking, settlement,or soil liquefaction.These conditions occur in <br /> areas underlain by cohesionless soils of low density sometimes in association with a shallow <br /> groundwater table. <br /> EMC Title 19.37 (Critical Areas) Page 77 <br />
