20-084 Lyashenko PAGE 3 OF 22 3/27/2C This mapped stream is fed by stormwater infrastructure along S 2nd Ave (see Appendix) and exits a 12" culvert approximately 1.5' above grade, as the pipe emerges from a weedy ditch at a topographic break; the streambed under the pipe is <1' wide, shallow, and composed of gravelly -loamy substrate; from this point, the stream is conveyed by an excavated ditch into a brushy area dominated by Red -Alder and Himalayan blackberry (Alnus rubra and Rubus armeniacus, respectively) of the easterly buffer. The buffer at the head of the stream, as it exits stormwater infrastructure, slopes upward to the west at approximately 16% and breaks at S 2nd Ave; to the southwest the buffer is paved with gravel; and to the northwest the buffer is composed of maintained lawn, R. Armeniacus, and a hedgerow of even -age Douglas -Fir (Pseudotsuga menziesii, see photo sheet); no surfacewater was observed in the western buffer. Wildlife observed in the buffer was limited to passerine birds; indicators of other wildlife presence, such as browsing, trails, scat, and beaver activity, were not observed at the time of the site visit. Figure 3. Approximate Type Ns standard buffer. Image Source: Snohomish County PDS, 2018. All locations are approximate. Soil at the site is mapped as Everett very gravelly sandy loam, 0-8 percent slopes, which does not carry a hydric soil rating; the minor components of the soil mapped in the area do not carry hydric soil ratings. In consideration of the mapped soil data, the plant composition on the property, and the absence of wetland hydrology, I did not sample the site for hydric soil indicators.
