This report summarizes the existing surface and subsurface conditions within the site and provides general recommendations for the proposed site improvements. O�n� services were completed in beneral accordance with the proposal signed by you on Ap��il 2_5, 2015. I'he site consists of an existing structure that is located on a flat bench off of the eastern side of Seabreeze Way. A failing soldier pile retaining wall is located between the house and a steep s(ope below, which descends into Powder• Mill Gulch Creek I,arge tension cracks eYist within the driveway, and a large depression is located in the yard area between the house and the wall. We explored the area adjacent to the retaining wail with three test pits extending to depths in the range of 2.0 to 8.0 feet below the existing ground surface. Our explorations indicated that the existing wall failed in several locations and the wall backtill was in a wet, loose condition. We have concl�ided that the failing wall could be repaired; however, this needs to be evaluated by a structural engineer. We have provided general infonnation l�or wall repair and/or replacement, depending on the structural engineer's findings and ultimate conclusions. We also provide recommendations for drainage and erosion control.
