2.3 BOUNDARY DETERMINATION FINDINGS <br /> 2.3.1 Wetland A <br /> HGM Class: Slope <br /> Ecology Rating: Category IV <br /> City of Mukilteo standard buffer width: 40 feet <br /> V111111111 I <br /> j <br /> I <br /> Wetland A is a sloped feature located on the eastern side of the subject site. Dominant vegetation <br /> within the wetland includes Sitka willow (Salix sitchensis), Himalayan blackberry (Rubus anneniacus), <br /> Nootka rose (Rosa nutkana), and creeping buttercup (Ranunculus repens). Soils within the wetland <br /> are generally very dark grayish brown (10YR 3/2) sandy clay loam with dark yellowish brown <br /> (10YR 4/6) redoximorphic features. Soils sampled in the northern portion of the wetland <br /> contain a sublayer of dark gray (10YR 4/1) sandy loam with strong brown (7.5YR 5/8) <br /> redoximorphic features. These soil characteristics are consistent with the Redox Dark Surface <br /> (F6) and Depleted Below Dark Surface (F7) hydric soil indicators listed in the 2010 Regional <br /> Supplement. Soils were saturated at 10 inches below the surface following a long period without <br /> rainfall, during our August 2016 site visit (A total of 0.40 inches of precipitation total for the <br /> month of August). Additionally, the geomorphic position and sparsely vegetated areas within the <br /> interior of the wetland meet secondary indicators for wetland hydrology. <br /> The dominant species rate "facultative" or wetter, indicating that a hydrophytic vegetative <br /> community is present in the areas mapped as wetland. <br /> Field observations indicate that the area mapped as wetland is flooded, ponded, or saturated long <br /> enough during the growing season to develop anaerobic conditions in the upper part of the soils. <br /> Therefore, the vegetation, soil, and hydrologic criteria are all met for the on-site wetland. <br /> Mundorf-8th St 8 Critical Area Study & <br /> WRI#16233 Mitigation Plan <br /> March 2 0/6 <br />
