AI'PENDIX A PIELD (s\PLORATION AND LAI30RATORY 7'E�1'ING Ret�il Buiiding Cvcrett, Washington On Scptciubcr 18, 2009, wc obscivcd thc drilling of 3 lest horings to a maximum depth of approximately 16 feel belo�� existing site grades. Thc borings �r•ere drilled using a Uvck-mounted drill rig and advanced with Uollow- stem auger. Thc Ics1 boiing loc�tions are shown on l�igure 2. The locations were approximatcly delcnuined by mcasurir.g from existing si�e tealures, ?lie IIoring Logs are prescnted on Pigures A-2 Airougl� A-4. A senior enginecring geologist from our of�ce conducied the field exploration, classificd the soils eucomucred, maintained a log of each boring, obtainecl representative soil samples, and observed pertinenl site fealures. Soil samplcs were obtained in general accordancc with American Socicty for Testiug and Materials (ASTM) Test Designation D-I SS6. Using this procedure, a two-inch (ou�side di�mcter) xplil barrcl samplcr �vas driven inlo tl�c ground 18 inches usiug a I40•pound hammer free fallir.g a I�eigl�l of 30 incl�es. The numbcr of blows rcyuired lo drive the snmpler 12 i��cl�es aftcr an i�utial G-inch sct is refcrted to as tl�c Standard Penetration Resistance value or N valuc. Tl�is is an indcx rclated to thc wnsistency of cohesive soils and relalive densily of cohesionless malerials. h values obtained for cach sampling inlcrval are recorded on the Boring Logs. All soil samples were visually classified in accordance wi�h ihe Unificd Soil Classificntion System (USCS) described on Pigure A-l. Keprescntaiive soil samples ob�ained frmn �he les� Uoiings were placcd in sealed conlaincrs and laken to om laboraloiy for furllier examination and tcsting. Tlie moisture content of encb sample u�as measurcd .md is rcpor�cd on fhe coiresponding Boring Logs. Grain size analyscs werc performed on four of !he samples, ihe resulls of which are shown on Pi�ues A-S ;md A-6. Projcct No: T•G366 � �
