Oricntation Scveral data plots were sampled and labelcd in alphabetical sequencc. Among these, hvo plots were selected;one exhibiling positive wetl;u�d indicators and�ne e�ibiting negative wedand(upland)indicators. These plots remain labcled w"1t neon orange flags in the field for verification. Betwcen the t�i�q a ncon-pink Ilagged stake marks the dividir:�line, indicating the wetland edge. Some plots were performed as control sites to establish the lack of wetland indicators in suspect areas. In addition,orangc Ilagging was hung along the OH�VM of the strcam channel to aid in field survcy. FINDINGS Gata was collected at sevcr:�l sessions from I'ebruvy ]":u�d 2"�,2007. Wcather conditions werc cloudy and cool, and closely associated with intermittent rain cvents timt yiclded moist soils necessary for accurate identification as well as active stream Ilow. The parameters below discuss general chazacterisiics of the plots sampled. Data shcets supporting the delineation are attached at the end of the report. Representalive dclincation of the wetland is mapped to aid in field study and verification (see fig. 4). Vegetation The US Pish and Wildlife Department's ]988 National Wetland Inventory(fig. 3)does not document wetlands in the area. Field conditions indicated Uie presence of minimal but qualifying forested co��er.The ilora of representative samples consisted primarily of Tht ja plicala, dlnus rufira, and Salix lasiandra in the forest canopy,with a shrub layer dominated by Rubus spectabr(is, and Ranunctd:�s repens in the wetland positive samples. Upland plots primarily consisted of Tht ja plicata with shivb Polystichum m:mi(ian and inv3sive Hedera helix as ground cover. Soils 1'he Natural Rescues Conservation District Snoliomish County Soils Survey designates the areas soil type as Alderwood Urban Land Complex 2-S%slopes(fig. 5 A&B). Thesc soils arc moderately well drained with rapid pertncability.A&B Inycrs arc deep over hardpan and are dark grayish brown. These soils have been in association with human devclopment for such an extended length of time that their parent types in intermixed and indistingwshable. There is also a conflict with these soils in d�eir suitability for drainfields.These soils by nalurc havc hardpan at their seasonally high water tables, leading to perched effluent that can causc system failurc in periods of high rainfall. �
