2. The substrate is predominantly undrained hydric soil; 3. The substrate is non soil and saturated with water at some time during the growing season of each year. Wetlands include all areas waterward from the wetland edge. Where the vegetation has been removed, or substantially altered, a wetland shall be determined by the presence or evidence of hydric or organic soils. "Wetland boundary" means,for the purposes of the calculation of the area of the wetland,the total extent of the wetland, both on-site and off-site. "Wetland class" means a description of vegetation habitat based on the predominant life forms that occupy a particular layer of vegetation and possess an aerial coverage of thirty percent or greater of the entire wetland.The basis for these descriptive classes is derived from the Wetlands Taxonomic Classification System of the United States Fish and Wildlife Service (Cowardin et al., 1979). "Wetland, contiguous" means wetland systems connected by hydric soils or a significant surface water connection. For purposes of this title,wetlands will not be considered contiguous if the only hydrologic connection is a category I, II or III stream,or if the wetlands had historically been connected but are now separated by a legal fill or culvert which is one hundred feet or more in length. "Wetland edge" means the line delineating the outer edge of a wetland established by using the Washington State Wetlands Identification and Delineation Manual (Ecology Publication No. 96-94, 1997). "Wetlands, emergent" means a regulated wetland that does not qualify as a forested wetland or a scrub-shrub wetland with at least thirty percent of the surface area covered by erect, rooted, herbaceous vegetation as the uppermost vegetative strata. "Wetlands, Estuarine" means a tidal fringe wetland found along the mouth of a river and influenced by tidal activity. Water flows and depths are controlled by tidal cycles in the adjacent ocean. Estuarine wetlands have a salinity higher than 0.5 parts per thousand. "Wetlands, forested" means a regulated wetland with at least thirty percent of the surface area covered by woody vegetation greater than twenty feet in height. Wetlands of High Conservation Value "Wetlands, isolated" means those wetlands which: 1. Are outside of and not contiguous to any one hundred year floodplain or riparian corridor of a lake, river, or stream; and 2. Have no contiguous hydric soil or surface water connection between the wetland and another surface water body. "Wetlands, riparian" means those wetlands that generally occur within a riparian corridor that is contiguous to or have a surface hydrologic connection with a stream.Wetlands formed by hillside seeps Planning Commission Resolution 19-_ Page 23 Title 19 March 19, 2019
