Everett Land Association F'-2554 February 27, 1985 r,a9� 8 � FIELD EXPLO}2ATION AND LA�ORATORY TF.STING Our field ex��loration was perfc�rmed on February 20, 198:i. The subsurface concfitions were explored by excavatiny f<�ur test pits to a maximum depth of nine and one-half feeC beluw the existiny surEace at the approxima�e locetions shown on Plate 2. The locations oY tne test pits were ap��roximately determined by tape measurements from existiny siCe Eeatures . Elevations of t�•st pits were approximately determined by interpolation between plan contours. The locations antl elevations of tne test pits should be considered accurate only to the deyree implied by the method used. The Eield expluraCion was continuously monitored �y a yeotechnical enyineer trom our. firm who classiEied the soils encountered, maintained a log oE each test pit, obtained representative bulk soil samples and observed pertinent site features. Soils wera classified visually in the field according to the Unified Soil Classification System which is presented on Plate 3, Legend. The consistency of the soil was estimated based on penetrometer tests, the eEfort required to excavate the soil, the stability of the trench walls and other factors . Logs of the individual test pits are presented on Plates 4 and 5, Test Pit Logs. The final logs represent our interpretations of tlie fieZd legG and th� results of the laboratory examinacion and test of field samples. The stratification lines on the logs represent the approximate boundary between soil types. In actuality, the transition may be gradual. Shear strengths ef. undisturbed soils were measured where prac- tical in the field with a penetrometer. Thes? results are recozded on the test pit logs at the appropriate sample depth. , Representative soil samples were placed in closed containers and relurned to our laboratory for further examination and test- ing. Visual classifications were supplemented by index tests such as sieve analyses and Atterbery Limits on reoresentative samples. Moisture determinations were performed' •on all samples. Results of inoisture determinations, toyether with classifications, are shown on the test pit logs inciuded in this report. The results of two sieve analyses are illustrated on PZate 6, Grain Size Analyses. LT_MITATIONS Our recorr�mendatiens an�l conclusions are based on the site materials observed, selective laboratory testing and engineering analyses.
