MDR We visited the silo today at the request of Dan Kure to evaluate foundation subgmdc and setback Barn the steep slocc for the planned residence. We prepared a geotechnical en;norting report for Dais property titled "Preliminary Geotechnical Engineering Evaluation — 1919 Mukiltoo Boulevard — Evcn:tt Washington," dated October 20, 2005. We also prepared a building setback memorandum for the project dated January 28,203 0. Upon arrival we met with Dan and the earthwork contractor Carl Hall with Dig -It excavation. The foundation excavation had been completed for the eastern portion of the residence and the excavation for the weslen portion of the residence was underway. The excavation was made with three tiers stepping down the gently sloping building pad area. The excavation ranged from about two to five feet in depth. The walls of the excavation exposed a surficial layer of organic soil underlain by a vveathezod horizon of silty sand and sand with silt and roots. The foundation subg:ade soils exposed in the bottom of the excavation consisted of gray to brown silty fine to coarse sand with gravel, and sand with silt ntc gravel. In general the exposed subgrade could be penetrated about I to 4 inches with a 5!-inch diameter steel probe rod uncermoderate pressure and was interpreted as medium dense to dense native soil. The foundation excavation for two lightly Ioaded pillars on the west side of the residence was not completed while we were on site. We measured the setback form the top of he >t eep slope to the staked locations for tho pillars. The pL:tmed pillar locations did allow for the recommended 25-foot setback for lightly loaded st:tctures. Based on our observations while on site, the wes,-rn footing line of the residence t1,111 also be locate] with the recommended eifm--live setback of at least 35 feet from the top of the steep slope. The material from the excavation was being stockpiled on site away from the slopes and then loaded into dump trucks and exported from the site. We have been providing construction monitoring services on a part time basis. Our opinions and recommendations are based on our on -site observations only, it is our opinion that the foundation subgrade evaluated todav should provide adequate support for the planned foundation loads_ Tic locations of the residence and the lightly loaded structures were in general accordance with the plans and ourroconnnendations for their setback from the top of the steep slope.
