Soils in all othcr locotions on-si�c wcrc dctcrmincd �o bc non-hydric bascd on soil ma�rix chroma <br /> colors of 2 or highcr in thc "B"!�oriron and thc lack of rcdoximorphic features. <br /> Ve�etalion. The vcgctation in Wetland A was dominated by reeJ canarygrass (Appendix A). Red <br /> alder, westem reJ cedar, black cottomvood, ]limalayan blac!<berry, and salmonberry are present in <br /> varying amou �s along Aie wctland perimetcr. All of these plants, except Fiimalayan blackbcrry, <br /> have an indicator status of�AC or FACW. Thcrefore, hydrophytic vegetation was dctermined to <br /> bc prescnt. <br /> The upland vegetation along the perimeter of Wclland was dominated Uy Ilimalayan blackberry, <br /> with rcd aldcr saplings, black cottomvooJ, bittcr chcrry (Pnu�tis emnrgina�a) saplings, and Vailing <br /> blackbcrry(Rubr�s vilifclius)co-dominanis in somc of thc sunounding arcas. <br /> Ilydrology. Soiis were saturated_to thc surf<�ce in Wetland A during the investigation. Standing <br /> �vatcr was obscrvcd at 3 inches depth. The drainage that WcUand A spans appears to be thc primary <br /> source of hydrology. Thc bottom of thc drainage ditch is roughly %z-foot lowcr than a�ljacent <br /> portions of Wetland A. Soil moisture within tLe wetland is likely influcnced lhrough subsarface <br /> hydrologic exchange. I iowevcr, the drainagc also appears to ovcrtop as evidenced by croded ditch <br /> slopes where �he drainage passes througli the wcUand and sand deposits in adj:icent portions of thc <br /> weUand. Given its position in a depressionnl arca, Nctland A also likcly reccivcs surfacc runoff <br /> from adjaccnt areas upslopc. <br /> �VeQand �unetions. iluc to the small sizc (d,2G8 squarc fect) and degraded nature, Wctland A <br /> p-ovidcs minimal fiuictions. Its proximity to thc sc:,sonal drainagc and its siluation in a slight <br /> depression indicate lhat it provides some stomnvater attcnuation. Ilowever, the benefits are <br /> minimal due to thc small volumc of watcr it is capable of retaining. Groimdwater exchange <br /> fimctions are discoanlable given thc small size. Wetland A provides minimal wildlife habitat <br /> fimctiona because it is small and a si�iificant portion is dominated by reed canarygnss, an invasive <br /> �vecd. Ho�vever, the shrub and herbaccous vcgc�ation components likely pnvide cover for <br /> common passcrinc birds, such as song sparro�v (Afelosprzn melorlia), dark-eycd junco (Jturco <br /> hyemnlis), spottcd tow6ce (Pipr/o mnculnhrs), and Atncric.�tn robin (Ttrrdt�s mrgrntorit�s). Past and <br /> on-going disturbancc has resulted in an area dominated by wceds, with some portions bvren and <br /> trampled Gom foot traffic and clu:tcrecl with litter. As a result, Wetlmid .1 provides little aesthe.ic <br /> fimction and virlually no educational opportunity in its current statc. <br /> �VeUand Cl:issifir.tition. Wctland A is classificd as a palustrine scn�b-shnib/emergent wetland <br /> �vith a seasonally saturated water regime (PSS/EN1Y) follo�ving the USFWS classification system <br /> (Cowardin et al., 1979). Wetland A is not associatecl with a higtt-quality wetland community a�u; <br /> does not wver at Ieast 5 acres. Thcreforc, it docs not qualify as a Categery I wedand (Exccptional <br /> Resource Valuc) following the City of Everett's MuniciU�il Code. <br /> According to thc City's Code, Category II �vetlands are idcntified as those wetlands that provide <br /> "Significant Resource Value"�id typically cover at Ieas! 1 acre.
