Page 3 Mr. and Mrs. Darrel Freudenburg result of continuing saturation of loose fill material which had been placed on a sloping natural ground surface. According to the report, the fill slope may continue to slough and yield in a downward direction over a period of many years regardless of any erosion of the toe of the fill or the natural soils. The report further concludes that the portions of the property BOE//VG characterized by steep, natural slopes have had a history of instability. Slope failures and surface creep form the mechanism by which the Powder Mill Gulch was formed. The report indicates such movements may be expected to continue and could at some time in the future become critical. t B. Landau Associated Report dated May 10, 1984 - Engineer Consultation - Residence of Mr. and Mrs. Darrel Freudenburg According to this report - prepared at your request - slides on the property to the east of the creek have I occurred for a great number of years and probably extend back to prehistoric time. The soil closer to the creek bed and probably underlying the house includes interglacial soil deposits frequently associated with j slides in the Puget Sound region. Some of the preliminary conclusions in this report are as follows: 1. Erosion by Powder Mill Gulch Creek has probably I contributed to the slumping of the soil between ? the house and the creek. 2. Some of the slumping that has occurred has probably caused partial diversion of the creek to the west, where it would be more prone to undercut land between the house and the creak. 3. Earth slides and slumping to the east of the creek include both recent and prehistoric movement. Much of the earth movement may be attributable to spring activity, although undercutting contributes to erosion and slumping. This report recommends that immediate steps be taken to stabilize the bank adjacent to the house in order to prevent loss of the structure. The report also recommends that surface water from downspouts or other sources not be permitted to discharge on or above the slope..
