.. - SUBSURFACE EXPLORATION, GEOLOGIC HAZARDS AND PRELIMINARY GEOTECHNICAL ENGINEERING REPORT GOLDBERG PROPERTY 4700 BLOCK OF GLENHAVEN DRIVE EVEREI"f, WASHIIVGTON January 15, 1998 Project No. G97246A I. PROJECT AND SITE CONDITIONS _ 1.OINTRODUCTION � This report presents d�e results of our subsurface exploration, geologic hazards and preliminary geotechnical engineering study for the proposed single family residence to be _ constructed on the Goldberg property. The proposed building location and approximate locations of the explorations accomplished for this study are presented on the Site and Exploration Plan, Figure 1. In the event that any changes ui the nature, design or location of the strucmre are planned, the conclusions and recommendations contained in this report should be reviewed and modified, or verified, as necessary. 1 .1 Purpose and Scone The purpose of this study was to provide subsurface data to be utilized in the design and ' development of the siibject project. Our study included the excavation of exploration pits, completion of geologic studies, and a review of the USGS geologic map of [he Everett Quadrangle by James P. Minard to assess the rype, thicl�ess, disu-ibution and physical properties of the subsurface sed'unents and shallow b ound water conditions. Geologic hazard evaluations �nd engineering studies were also conducted to determine suitable geologic hazard mitigation techniques, the depth to foundation bearing sedimenu, the type of suitable foundation, allowable foundatiun soil bearing pressures, anticipated foundation settlements, iloor support recommendations, drainage and erosion coasiderations. This report summarizes our current field work and offers geologic hazard mitigation and ;eotechnical design recommendations Uased on our present understanding of the project. ].2 Autliorization Nritten authorization to procced with d�is study was granted by Mr. Hrnvazd Goldberg. Our study was accomplished in general accordance �vith our proposal dated August 22, 1997. This report has been prepared for the exclusive use of Howard Goldberg and his agents, for specific application to this project. Within die limitations of scope, schedule and budget, our services have becn perfonned in accordance with �enerally accepted geotechnical eneineering and
