i • Subsurface Exploration,Geologic Hazard,and Jandwicz Property Geotechnlcal Engineering Report Everett,Washington Project and Site Conditions I. PROJECT AND SITE CONDITIONS 1.0 INTRODUCTION This report presents the results of our subsurface exploration, geologic hazard, and geotechnical engineering study for the subject project. Our recommendations are preliminary in that construction details have not been finalized at the time of this report. The location of the subject site is shown on the "Vicinity Map," Figure 1. The approximate locations of the explorations accomplished for this study are presented on the "Site and Exploration Plan," Figure 2. In the event that any changes in the nature or design of the proposed lot layout are . planned, the conclusions and recommendations contained in this report should be reviewed and modified,or verified,as necessary. • 1.1 Purpose and Scope The purpose of this study was to provide subsurface data to be used in the design and development of the subject project. Our study included reviewing available geologic literature, drilling two exploration borings, and performing geologic studies to assess the type, thickness, distribution, and physical properties of the subsurface sediments and shallow groundwater conditions. Geotechnical engineering studies were also conducted to assess the type of suitable foundation, allowable foundation soil bearing pressures, anticipated settlements, basement/retaining wall lateral pressures, floor support recommendations, and drainage considerations. This report summarizes our current fieldwork and development recommendations based on our present understanding of the project. 1.2 Authorization Our study was accomplished in general accordance with our proposal dated January 29, 2018 and authorized February 2, 2018. This report has been prepared for the exclusive use of Mr.Ted Janowicz and his agents for specific application to this project.. Within the limitations of scope,schedule,and budget,our services have been performed in accordance with generally accepted geotechnical engineering and engineering geology practices in effect in this area at the time our report was prepared. No other warranty, express or implied, is made. Our observations, findings, and opinions are a means to identify and reduce the inherent risks to the owner. 2.0 PROJECT AND SITE DESCRIPTION The property is a flag lot at 1329 Madrona Avenue in Everett, Washington and is part of a well-developed residential neighborhood. The parcel is slightly less than % acre in area and is undeveloped. We understand from our discussions that the proposed plan is to build a May 10,2018 ASSOCIATED EARTH-!SCIENCES,INC. trod-17O649E0022-Prolects1201706491KElWP Page 1
