RESULTS OF INVESTIGATION Wetland and adjacent upland plant species are described as in the overstc.y, shrub or herbaceous tayer when applicabie. from the site-spec'fiic investigation are reported below. General Site Information being dominant, common, or scattered The data and observations resuRing The subject property is an irregularly shaped 6 acre parcel. The site consists of moderate to steep slopes in the eastem part of the site, and gentle slopes in the west, generally sloping toward the west. Two existing residences are located on the site in the northeast comer of the site adjacent to 52n° Street. A gravel access road enters the site near the northeast property comer, extending down slope to the west. Hydrology The natural topography of the subject parcel consists of steep to gentle slopes generally sloping towards the west. A wetland is locatecf in the eastem part of the site on a gentle slope, which discharges to Pigeon Creek, located at the eastem property boundary. Hydrology of the site is predominantly derived from groundwater discharge, and secondarily from seasonai stormwater. Hydrology on the site was observed in the field in July 2006. VeaetaUon The vegetation on the subject property consists of a forest community, with the exception of the area directly around the residences. The overstory of the forest community consists of a mix of deciduous and confferous trees, dominated by westem hemlock (Tsuga heterophyl/a). Other species observed include Douglas fir (Pseudotsuga menziesir) red alder (A/nus rubra), western red cedar (Thuja plicata), and big-leaf maple (Acer macrophyllum). The understory is dominated by vine maple (Acer ci�inalum) and sword fem (Polystichum munitum) in the up�ands and saimonberty (Rubus spectabilis) and skunk cabbage (Lysichiton americanum) �n the wetlands. 7 I�
