PNW Home Builders, LLC ES-2598.03 May 2, 2013 Page 2 If the above design assumptions are incorrect or change, ESNW should be contacted to review the recommendations in this report. ESNW should review the final design to confirm that our geotechnical recommendations have been incorporated into the plans. SITE CONDITIONS Surface The subject site is located southeast of the intersection between The Lowell Riverfront Trail and 41st Street and along the Snohomish River in Everett, Washington.. The approximate location of the property is illustrated on Plate 1 (Vicinity Map). The site is irregular in shape and vacant. We conducted one site visit to access existing site conditions as part of preparing this report. The site is bordered on all sides by vegetation. The Lowell Riverfront Trail passes near the site along the north and east site boundaries. The site has been subjected to past fill activities, resulting in a generally level topography across the site, with approximately five feet or less of total elevation change. The site has been cleared of vegetation, with scattered piles contained stumps, brush, and rubbish present along the west site boundary. Subsurface The boring logs included in the referenced GeoEngineers report were reviewed. The approximate boring locations are depicted on Plate 2 (Boring Location Plan). Please refer to the boring logs provided in Appendix A for a more detailed description of the subsurface conditions. Topsoil Topsoil was reported at one of the five boring locations and was limited to the upper six inches of existing grades. The topsoil was characterized by dark brown color and the presence of fine organic material. Fill Fill was reported at all five boring locations and consisted primarily of brown fine to medium sand with trace gravel and brown or gray silty sand with gravel (Unified Soil Classifications SP and SM). Fill depths were generally on the order of 11 to 20.5 feet with the soil in a moist to wet condition. The fill material was largely devoid of deleterious debris and organic material and was reported to be in a medium dense condition. Earth Solutions NW,LLC
