Chapter 19.04 EMC, Definitions Page 47 of 55 <br />The Everett Municipal Code is current through Ordinance 4031-24, passed May 22, 2024. <br />those areas defined as landslide hazard areas, erosion hazard areas, and seismic hazard areas, <br />or other soils which have been determined by the public works director or the building official <br />to be unsuitable for building foundations or structural support. <br />“Upper bank” means that portion of the topographic cross-section of a stream which extends <br />from the break in the general slope of the surrounding land to the ordinary high water mark. <br />“Wetland boundary” means, for the purposes of the calculation of the area of the wetland, the <br />total extent of the wetland, both on site and off site. <br />“Wetland class” means a description of vegetation habitat based on the predominant life forms <br />that occupy a particular layer of vegetation and possess an aerial coverage of thirty percent or <br />greater of the entire wetland. The basis for these descriptive classes is derived from the <br />Wetlands Taxonomic Classification System of the United States Fish and Wildlife Service <br />(Cowardin et al., 1979). <br />“Wetland, contiguous” means wetland systems connected by hydric soils or a significant surface <br />water connection. For purposes of this title, wetlands will not be considered contiguous if the <br />only hydrologic connection is a Category I, II or III stream, or if the wetlands had historically <br />been connected but are now separated by a legal fill or culvert which is one hundred feet or <br />more in length. <br />“Wetland edge” means the line delineating the outer edge of a wetland established by using the <br />Washington State Wetlands Identification and Delineation Manual (Ecology Publication No. <br />96-94, 1997). <br />“Wetland, estuarine” means a tidal fringe wetland found along the mouth of a river and <br />influenced by tidal activity. Water flows and depths are controlled by tidal cycles in the adjacent <br />ocean. Estuarine wetlands have a salinity higher than 0.5 parts per thousand. <br />“Wetland mitigation bank” means a site where wetlands are restored, created, enhanced, or, in <br />exceptional circumstances, preserved, expressly for the purpose of providing compensatory <br />mitigation in advance of authorized impacts to similar resources. Banks typically involve the <br />consolidation of many small wetland mitigation projects into a larger, potentially more <br />ecologically valuable site. Such consolidation encourages greater diversity of habitat and <br />wetland functions. It also helps create more sustainable systems. Banks provide a greater
