Geotechnical Engineering Evaluation NGA File No. 961916 Mason Residence Addition and Deck August 24,2016 Everett,Washington Page 15 2e changes should the conditions differ from anticipated, and to evaluate whether construction activities comply with contract plans and specifications. USE OF THIS REPORT NGA has prepared this report for Ms. Caroline Mason and her agents, for use in the planning and design of the development planned on this site only. This report is a specific evaluation of the steep slopes and the proposed addition, and should not be considered an in-depth evaluation of the entire site or the existing residence. The scope of our work does not include services related to construction safety precautions and our recommendations are not intended to direct the contractors' methods, techniques, sequences,or procedures,except as specifically described in our report for consideration in design. There are possible variations in subsurface conditions between the explorations and also with time. Our report, conclusions, and interpretations should not be construed as a warranty of subsurface conditions. A contingency for unanticipated conditions should be included in the budget and schedule. All people who own or occupy homes on or near hillsides should realize that landslide movements are always a possibility. The landowner should periodically inspect the slope, especially after a significant storm event. If distress is evident, a geotechnical engineer should be contacted for advice on remedial/preventative measures. The probability that landsliding will occur is substantially reduced by the proper maintenance of drainage and erosion control measures at the site. Therefore, the homeowner should take responsibility for performing such maintenance. Consequently,we recommend that a copy of our report be provided to any future homeowners of the property if the home is sold. We recommend that NGA be retained to review project plans as they are being developed. We also recommend that we be retained to provide monitoring and consultation services during construction to confirm that the conditions encountered are consistent with those indicated by the explorations,to provide recommendations for design changes should the conditions revealed during the work differ from those anticipated, and to evaluate whether or not earthwork and foundation installation activities comply with contract plans and specifications. We should be contacted a minimum of one week prior to construction activities and could attend pre-construction meetings if requested. Within the limitations of scope, schedule, and budget, our services have been performed in accordance with generally accepted geotechnical engineering practices in effect in this area at the time this report was prepared. No other warranty,expressed or implied,is made. Our observations,fmdings, and opinions are a means to identify and reduce the inherent risks to the owner. o-o-o NELSON GEOTECHNICAL ASSOCIATES, INC.
