v <br /> July 18, 2022 Earth Solutions NW LLC <br /> ES-8528.01 Geotechnical Engineering,Construction <br /> Observation/Testing and Environmental Services <br /> Pacific Ridge — DRH, LLC <br /> 17921 Bothell-Everett Highway, Suite 100 <br /> Bothell, Washington 98012 <br /> Attention: Ms. Dagny Cook <br /> Dear Ms. Cook: <br /> Earth Solutions NW, LLC (ESNW), is pleased to present this report to support the proposed <br /> project. Based on the results of our investigation, construction of the proposed residential <br /> development is feasible from a geotechnical standpoint. Our field observations indicate the <br /> subject site is underlain by about one to five feet of existing fill and topsoil. Underlying the fill and <br /> topsoil, medium dense to very dense glacial till deposits extend to depths of at least 10 feet below <br /> existing grades. <br /> Topsoil present below the existing fill will need to be removed from structural areas, and existing <br /> fill will need to be removed and/or reworked to the specifications of structural fill. New structural <br /> fill should be placed on competent native soil or reworked existing fill. <br /> After completing earthwork activities in accordance with recommendations in this report, the <br /> proposed structures can be supported on conventional spread and continuous foundations <br /> bearing on undisturbed, competent native soil, recompacted native soil, or new structural fill. <br /> Where loose or unsuitable soil conditions are encountered at foundation subgrade elevations, <br /> compaction of the soils to the specifications of structural fill, or overexcavation and replacement <br /> with suitable structural fill will likely be necessary. A representative of ESNW should confirm <br /> suitability of foundation subgrades at the time of construction. <br /> This report provides geotechnical analyses and recommendations for the proposed residential <br /> development. The opportunity to be of service to you is appreciated. If you have any questions <br /> regarding the content of this geotechnical engineering study, please call. <br /> Sincerely, <br /> EARTH SOLUTIONS NW, LLC <br /> b'1W6__ dvy�_' <br /> Brian C.
