Emergent vegetation is dominated by bulrush(Scirpus microcarpus), creeping buttercup <br /> (Ranunculus repens), soft rush(Juncus effusus), and nonnative lawn grasses. The shrub <br /> component is predominately Himalayan blackberry(Rubus armeniacus)that has been <br /> periodically cut. Ponding is limited. Saturation within the wetland was found in the lower soil <br /> layer where the sand component is high. Standing water in the soil pits was observed at about 10 <br /> inches,confined to the sandy soil layer. No outlet was observed. It appears the wetland drains <br /> subsurface through the sand layer. Soil pits taken down slope of the wetland did not contain <br /> saturated soil,hydric soil indicators, or a high-water table. The pits were left open for more than <br /> 15 minutes and no water was observed. These soils had a low sand content compared with that <br /> within the wetland. <br /> iri' mss^ , �� .t <br /> - trc' <br /> `, aysFte1 i T� • <br /> '♦ <br /> 5 Z ' tis ^ <br /> Z yy' <br /> b y 4, ig L}y4;40:Nat h 3;1 4 { <br /> 44, <br /> '� sal �+&��, 7�` t 1 T <br /> ,, dt r� -V: ,� ,4? :;t ,g' �.��„,, r�,iaa rr Figure 6: Wetland A <br /> 11--;.,!L "s.:all ^� rtf�(. -^'';',.:}L; Y- .: . ,'.. uwtr 1 is <br /> l "� °�Y fly , -if,, ., .,' ' P+ <br /> 0 <br /> :,;t > `: . <br /> Precipitation and overland flow provide water to the wetland. Water storage functions of the <br /> wetlands include replenishment of soil moisture and groundwater storage. A primary function of <br /> the wetland is to improve surface and ground water quality through the removal or conversion of <br /> nutrients, contaminants, and other elements due to the proximity of paved roads and residential <br /> development. <br /> Neotropical migrants, and year-round resident birds not sensitive to human disturbance are <br /> expected to use the area. <br /> Wetland buffers are lawn/landscaping. These plants provide minimal structure and plant <br /> diversity; however, do function to filter overland flow before it reaches the wetland. <br /> Wetland A scores 14 total wetland function points with 6 points for water quality functions; 4 <br /> points for hydrological functions; and 4 points for habitat functions. <br /> Standard buffer width requirement for Category IV wetlands that score 4 points for habitat have <br /> a minimum buffer width of 35 feet per EMC 19.37.110 A. 1. c. This buffer does not overlap the <br /> proposed property. <br /> 7 <br />
