The property is located at 1901 West Mukilteo Boulevard in Everett, Washington, as shown on the Vicinity Map in Figure 1. Our services were completed in general accordance with our proposal signed by you on October 11,2016. INTRODUCTION The purpose of this study is to explore and characterize the surface and subsurface conditions within the vicinity of the top of the steep slope below the residence in order to provide our opinions with respect to the existing stability conditions within this area and provide recommendations for the proposed improvements between the residence and steep slope area. We understand that the proposed development within the site includes patio improvements within the yard area between the existing residence and the steep north-facing slope below the residence. These improvements would likely include lowering the yard area between the residence and slope approximately 42-inches to be slightly lower than the partial daylight basement of the residence. We also understand that you plan to construct a new upper level addition along the eastern portion of the residence. TO(p TING 2 2/
