The floor grade of the house lies roughly 39 feet or more above the bottom of the gulch. The house was built on the property sometime BOEAVG prior to the 1940s. As early as the 1960s, the creek in Powder Mill Gulch was observed to carry a water flow as deep as five feet in the vicinity of your property. As early as 1964, you have stated that you noticed a deterioration in water quality in the creek. Boeing's development of its Everett property did not begin until mid-1966. 2. Geotechnical Reports A number of geotechnical investigations of the property have been made since 1966. The following is a summary of the rer--rtc issued as a result of those investigations. f FlF A. Dames and Moore Report dated December 8, 1966 - Report of Site inspection - Freudenburg Property - Powder Mill Gulch This reports states that retention of some of the fill material between the house and the creek had been attempted by the placement of logs and timbers, some of which had failed at the time of this investigation. According to the report, those failures were not recent. The report states that the fill along portions of the slope is obviously unstable and subject to movement. The surface soils are generally loose and composed of miscellaneous silty and granular materials. The report notes that observation of the creek bed indicated a fairly substantial flow of water carrying some silt and clay soil. The creek had been observed to carry as much as five -font depth of water at this location. The report concludes that any erosion occurring as a result of waters carried by the creek in Powder Mill Gulch in the vicinity of the property was not significantly endangering any portion of the property. Movements of the fill which are apparent are the logical
