To qualify as wetland,three criteria are met. These criteria include the presence of vegetation, soil <br /> types, and hydrology that are characteristic of wetland areas(WA ST DOE 1987). <br /> Vegetation of wetlands consists of plants typically adapted to thrive in areas where anaerobic soil <br /> conditions prevail for a long portion of the growing season. Categories based on the likelihood <br /> of a plant occurring in association with wetland areas are the basis for determining whether a site <br /> meets the vegetation criteria. Areas within the property that are dominated by facultative (34- <br /> 66%probability wetland indicator); facultative wetland(67-99%), and/or obligate (>99%) <br /> indicator plants meet the wetland criteria for present of hydric vegetation. <br /> Soil types that occupy wetlands are hydric soils, or soils that are characteristic of reducing soil <br /> conditions. A hydric soil is a soil that formed under conditions of saturation, flooding, or ponding <br /> long enough during the growing season to develop anaerobic conditions in the upper part. (USDA <br /> NRCS 1995). Soils on the property are mapped as Alderwood gravelly sandy loam. Alderwood <br /> series are moderately well drained soils found on ridges and hills. Alderwood soils were formed in <br /> glacial drift and/or glacial outwash over dense glaciomarine. Soils found within the wetland are <br /> clayey silty loam with a very sandy loam layer at 10-12 inches. Where the sand layer was deeper than <br /> 20 inches,saturation was not found. <br /> . ... <br /> fc • :41 Figure: 5 Soil Map <br /> 3—Alderwood gravelly sandy loam <br /> CS .r `Jr <br /> [•94.v_'YYV4�.3k,', !, meq` <br /> The term"wetland hydrology"encompasses all hydrologic characteristics of areas that are <br /> periodically inundated or have soils saturated to the surface for a sufficient duration during the <br /> growing season. <br /> Wetland A <br /> A 491-square foot Category IV slope wetland is found on the parcel to the south. The wetland is <br /> located along the base of fill associated with the home site south of the property line. The <br /> wetland is located within an area of the property that has been maintained as landscaping(Asian <br /> pear trees, lawn)in the past. <br /> Cowardin classification is Palustrine emergent wetland with seasonal saturation. <br /> 6 <br />
