• w Scriven Residence Improvements-REVISED NGA File No 974316 <br /> 1901 West Mukilteo Boulevard November 29,2016 <br /> Everett,Washington Page 2 <br /> We were previously provided with a geotechnical report for the property titled "Scriven Property," dated <br /> May 10, 2012,prepared by Geotech Consultants, Inc. In this report, they provided recommendations for <br /> stabilizing the upper portion of the steep slope with shoring walls along with drainage improvements. We <br /> understand that the City of Everett has requested an updated geotechnical evaluation of the proposed <br /> improvements due to the geotechnical report being over one year old. For our use in preparing this report, <br /> we were also provided with a plan set titled"Scriven Addition/Remodel," dated September 28, 2016 and <br /> prepared by BC&J Architecture. <br /> SCOPE <br /> The purpose of this study is to explore and characterize the site subsurface conditions, and provide our <br /> opinions and recommendations regarding the existing slope stability and proposed development. <br /> Specifically, our scope of services includes the following: <br /> 1. Review available soils and geologic maps of the area, available plans, and previously <br /> prepared geotechnical reports for the property. <br /> 2. Explore the subsurface soil and groundwater conditions within the site with hand-augered <br /> holes. <br /> 3. Map the conditions on the slope and evaluate current slope stability conditions. <br /> 4. Provide recommendations for improving slope stability, including the use of light <br /> retaining structures, erosion control systems, and drainage improvements as needed. <br /> 5. Provide recommendations for foundation support for the additions, including minimum <br /> foundation embedment. <br /> 6. Provide an evaluation of the proposed addition setback from the steep slope. <br /> 7. Provide recommendations for earthwork. <br /> 8. Provide recommendations for temporary and permanent slopes. <br /> 9. Provide recommendations for slab subgrade preparation. <br /> 10. Provide recommendations for drainage improvements. <br /> 11. Provide recommendations for long-term slope maintenance. <br /> 12. Provide recommendations for your planned re-grading of your backyard. <br /> 13. Document the results of our explorations, findings, conclusions, and recommendations in <br /> a written geotechnical report. <br /> NELSON GEOTECHNICAL ASSOCIATES, INC. <br />
