attached wedand rating formJ The habitat function score for this wedand is 23 points. The Ciry of Everett requires a 105-foot bufler for this class of weUand (EMC 37.1 I O.A.I.b). A small cast-ilowing stream was also observed ofi'site to the south of thc site (sec Flgures I and 2). At its closcst point, the stream is approximately 20 feet south of the site, afier which it tlows farther away from the sitc to the southeast. It emerges from an ofl'site pipe onto the site. Thc stream is seasonal and is presumed to not contain fish; thereforc, it i: classified as a Typc Ns stream (EMC 37.160). Streams of this rype are required to have a 50-foot but%r measured from the ordinary high watcr mark (EMC 37.170). Wetland aod Buffer Imuacts SPG observed that wetland and wetland bufTer disturbance, in thc form of vcgetation debris placed thercin, extends partially into the onsite wetland and its associated 105-foot standard buffer (see Figure 2). Disturbance was also observed within the 75-foot standard stream buffer on the south side of the site. The vegetative debris in the wedand and buf%r is composcd primarily of sticks, twigs, leaves. and roots. In addition, some of the debris appears to have biodegraded pnrtially, and now consists of loose compost. Thc dcpth of the debris and compost material varies from 2 feet to 6 feet throughout the weUand and buf%r areas. A considerable portion of the disturbcd wctland and stream buffer arcas have been used (historically) as parking and work areas sincc beforc 1985; therefore, the ground is very compact in the majority of the buffer. The arca ouQined in �igure 1 shows a portion of thc current weUand but%r that was historically utilizcd by the nursery business since the 1980's (as evidenced by acrial photographs): this area is not considered part of the code enforcement case, as agreed upon during our mccting with Stevc Ingalsbe at the City of Everctt on December 6, 201 I. T'he total area of diswrbed wetland is approxi,natcly 5,000 square feet (st) (0.1 I acre); the line of debris ranges from 0 feet to 55 feet (maximum), as measured east from the wetland cdge (see Figure 2). The avcrage depth of debris is 3 feet; thcreforc, approximately 556 cubic yards of material is present in the wetland. Approsimately 8.000 sf (0.18 acres) of wedand/stream buffer. not counting the historically-used arca diswsscd above, wrrcnUy contains vegctation debris (sce Figure 2). f unctions pertaining to watcr quality, hydrology, and habitat and associated with the dcpmssional wetland have been slighdy disturbed by the 5,000-squarc-foot area of vegctation debris that was placed in the wetland. The 2- to G-foot depth of debris placed near thc wedand edge has inhibited flow of some runotT further into the wedand, and affected the surfacc- subsurface hydrologic connection. In addition, natural iiabitat for small mammals and birds has been impacted, in that.lense piles of dcbris are present in the area, rather than the natural, native vegetation communitics that werc formerl� present. The wedand/stream buffer impacts arc similar; water flowing through the bufler and into the wetland has changed, and habitats havc aTiny Posne►, Planfscapu — RuJoralion Plan Page 2 Prcpared by ShocAey Planning Group.
