The characteristics of an area that result in its classification as '\l,retland" have been formally defined by federal and state agencies. A1l wetland delineations must be prepared in accordance with the U.S. Army Corps of Engineers Xegr onal Supplement to the Corps of Engineers ll/etland Delineation Manual: Western Mountains, Valleys, and Coast Region, Version 2.0 (Ma1t 2010), The wetland delineation report will include how the wetland boundary was determined and include a map of the delineated wetland, data sheets, and descriptions of site characteristics in both upland and wetland. The methodology outlined in the Corps Manual is based upon three essential characteristics of wetlands: (1) hydrophl.tic vegetation; (2) hydric soils; and (3) wetland hydrology. Field indicators of these three characteristics must all be present in order to determine that an area is a wetlaad (unless problem areas or atypical situations are encountered). All wetlands identified using this methodology may be regulated regardless of size. Determining Wetland Edges Wetland edges were determined by establishing pairs of data points. In general, the wefland edge falls between the sampling plot with all three positive wetland requirements and where one or all of the requirements were not present. Other difficult situations encountered in identiffing wetlands are described in greater detail in the Corps Regional Supplement. Hy drop hytic Ve g etatio n Hydrophytic vegetation decisions are based on communities of species that tolerate prolonged inundation or soil saturation during the growing season. Vegetation sampling will follow the guidance ouflined in the Corps Manual. Several methods can be applied; however one method includes recording vegetation of a sampling point to determine if more than 50% of the dominant species have a wetland indicator status of OBL, FACW, or FAC. Dominance of plant species is deterrnined by calculating actual aerial cover within an appropriate radius for trees, shrubs, and herbaceous species at each data point. Commonly occurring plant species have been rated by the U.S. Army Corps of Engineers National Wetland Plant List (NIIPL), 2014 COE Western Mouwains. Vallevs. and Coasr. During the fieldwork, each species was recorded and given a rating based on indicator status and percent cover. The 2014 NWPL will be used in any wetland delineations or determinations performed after May 1, 20t4. Key to Wetland lndicator Status codes - Northwest Region (Source: USFWS, 1988, 1993): OBL Obligate: species that almost always occur in wetlands under natural conditions (est. probability >99%). FACW Facultative wetland: species that usually occur in wetlands (est. probability 67 to 99Yo),hritt are occasionally found in non-wetlands. FAC Facultative: species that are equally likely to occur in wetlands or non-wetlands (est. probability 34 to 66%). FACU Facultative uoland: species that usually occur in non-wetlands (est. probability 67 to 99o/o),btt are occasionally found in wetlands. UPL Upland: species that almost always occur in non-wetlands under normal conditions (est. probability >99%). Hydrophytic Soil A hydric soil is a soil that forms under conditions of saturation, flooding, or ponding lasting long enough during the growing season to result in an anaerobic upper layer (USDA-NRCS 1995). Hydric soils favor the growth and regeneration ofhydrophl.tic vegetation. The Natural Resources Conservation Service (NRCS), in cooperation with the National Technical Committee for Hydric Soils, has compiled lists of hydric soils. It is common, however, for a map unit ofnon-wetland (non-hydric) soil to have inclusions ofhydric soil, and vice versa. Therefore, field examination ofsoil conditions is important to determine if hydric soil conditions exist. In general, anaerobic conditions create certain characteristics in hydric soils, collectively known as "redoximorphic features" and include low chrom4 depletions, gleying, sulfidic material (rotten egg odor) and,/or high organic content within the soil immediately below the A-horizon. Holes were dug on the site and soil colors were described by texture, color name, value, and chroma (Munsell Color 2000). Soils were categorized in accordance with NRCS Field Indicators of Hydric Soils of the United States (Version 7.0,2010 with updates). This manual further defines organic soils, sandy soils, loamy and clayey soils with a numeric value. Wetland Hydrology Water must be present in order for wetlands to exist; however, it need not be present throughout the entire year. The standard requires 14 or more consecutive days offlooding, or ponding or a water table 12" or less below the soil surface during the growing season. The growing season has begun when two or more different non- evergreen vascular plaats are identified. Indicators ofhydrology may include, but are not necessarily limited to, ponded water, drainage pattems, drift lines, sediment deposition, historic records, water-stained leaves, cracking of the soil surface, oxidized root channels, and/or sediment deposits. The Regional Supplements provide methods for evaluating situations in wetlands that periodically lack indicators of wetland hydrology but where hydric soils and hydrophytic vegetation are present. Categorization Wetland categorization .is determined using the lYashington State Department of Ecolog/ (DOE) Wetland Rating System Revised (Ecologt Publication #14-06-029, Effective January 2015 and as amendcd), accofingto type and category of wetland. The wetland is assigred a score of High, Medium, or Low for wetland values; including water quality functiorL hydrologic functioq and habitat function. The total rating determines the category of wetland. Wetlands are rated as entire systems and quite often exceed project boundaries. Ratings range from Category I to Category IV. Buffers are assigned according to intensity of land use for specific parcel size using final numeric scores. Category I indicates wetlands with the highest quality of function for improving water quality, preventing flooding problems, and providing habitat. These are not replaceable and therefore receive the lmgest buffer and highest protection. Classilication Two classification systems are commonly used to describe wetlands. The hydrogeomorphic (HGM) system describes wetlands in terms of their position in the landscape and the movement of water in the wetland (Brinson, 1993). The U.S. Fish and Wildlife Service classification system (Cowardin et al., 1979) describes wetlands in terms of their vegetation communities; for example, emergent (PEM), scrub-(PSS) shrub, and forested (PFO) community t1pes.
