Project No.T-1091 Mr. Dave Williams �3os c �-Ies��HerZ way Aldrich and Associates �{ �� 810 -240th Street SE Bothell, Washington 98021 Subject: Geotechnical Evaluation Proposed Wi]liams Residence 7305 East Heather Way Everett, Washington Dear Mr. W;lliams: As requested, we have provided you with geotechnical consultation regarding the proposed construction of your ncw residence in �verett, Washington. On June 28, 1989, an engineering geologist from our office met with you at the site to examine the conditions exposed in the open excavation and provide you consultation relating to the geotechnica] aspects of house construction. At the time of our visit, much of the excavation for the house had been completed. Our representative examined the subgrade conditions exposed in the excavation which had been made as a series of level benches cut into the gentle hillside at the project site. Some perimeter footing lines had already been excavated at the time of our site visit, but no forms were in-place. In general, significant su�sur:ace dra:nage had been installed around the house area to intercept groundwater traversing through the clean glacial � outwash soils exposed in much of the excavation. The outwash soils directly overlie laminated dense and hard silt soils which appear to underlie the house pad at varying depths below the outwash. The general excavations observed appeared to be based in either the firm native sand and gravel or in the dense underlie native silt soi:s which probably underlay much of this hillside area. 15301 N.L 901h Street • Redmond, Washington 98052 • Phone (206) 881-55;0 • FAX No. tSG9•9173 Mailing �ddress: P.O. 13or 3338 • Redmond, Washington 91i073 I I
