c. Wh�t�muai typa o'soils are found on the site(for enmple, clay,iand,`nvd, peat, <br /> mukh)7 !f yoa Imow ihe eluiifiatioa of agricultunl aoib,:pecify them aod note,�oy <br /> prime tarmland. <br /> USU.A-SCS Snohomish Counry Aroa Soil Survry indicates the following soil types in the project <br /> •area: <br /> #1 Alderwood Gravelly�andy I.oam, 2-8%slope. <br /> #3 Aldrnvood Gravelly Sandy Loam, 15-25%slope. <br /> #32 McKenna Grtvelly Silt Loatn, 0-8%slope. <br /> #69 Tertic Medisaprists, nearly level. <br /> d. Are thcre:urface indicationt or history of unstable soils in the immediate vicinity2 If�o, <br /> dacribe. <br /> No. <br /> e. Dacribe the purpoae, type, and appro:imrte qurntitia of any filling or gndieg propoaed. <br /> Indicate aource of fill. <br /> Excavation and export of approximately 70,000 cubic yards of soil will teke place on-site to <br /> croate additional and enhance exxisting wetlands. �aproximately 13,5�0 cubic yards of topsoil will <br /> then be imported for wetland creation and enhanc�ment. The net amount of excavation will be <br /> appro�cimately 56,500 cubic yards. <br /> f. Could erosion occur as r result of clearing, conatruction,or use? If ao,generally describe. <br /> Yes; erosion could take place zt the site due to precipitation. <br /> g. About what percent of the aite will be covered w�ith impervious surf�ces after projat <br /> constructioa (for e:ample, Asphalt or building�)2 <br /> Approximately 4.7%of the site(2.2 out of 46 acres)will be covered by impervious surfaces <br /> (bathrooms, parking:ots, greenhouse and trail system). <br /> h. Propoaed meaaurd to reduce or control erosion, or other impacts to the art6, if any: <br /> This project will control construction related erosion impacts through the use of tanporary <br /> erosion control measures such as filter fabric fencing, hydroseeding, bioswales, and other BMP's <br /> appropriate for this type of construction activity. <br /> /�7 <br />
