Page 7 <br />Mr. and Itm. Darrel Freudenberg <br />result of continuing saturation of loose fill material <br />which had been placed an a sloping natural ground <br />surface. According to the report, the fill slope my <br />oomt,iae to slough and yield is a downward direction <br />ewer a period of many years regardless of any erosion of <br />the too of the fill or the natural soils. The report <br />further concludes that the portions of the property <br />NE/ARP abaracterised by steep, natural slop" have had a <br />histuy of instability. slope failures and surface <br />creep form the mechanism by which the powder Rill Gulch <br />was formed. The report indicates such movements may be <br />expected to continue and could at some time in the <br />future become critical. <br />s. Landau Associated Report dated Ray 10, 1984 - <br />Enginoor Consultation - Residence of Mr. and <br />Ms. Darrel Freudenburg <br />According to this report - prepared at your request - <br />slides on the property to the east of the crook have <br />occurred for a great number of years and probably extend <br />back to prehistoric tits. The soil closer to the croak <br />bed and probably underlying the house includes <br />interglacial soil deposits frequently associated with <br />slides in the Puget sound region. some of the <br />preliminary conclusions in this report are as follow: <br />1. Erosion by Powder Rill Gulch Crook has probably <br />contributed to the slumping of the soil between <br />the house and the crook. <br />2. same of the slumping that has occurred has <br />probably caused partial diversion of the crook <br />to the west, where it would be more prone to <br />undercut land between the house and the creek. <br />3. Earth slides and slumping to the east of the <br />crook include both recent and prehistoric <br />movement. <br />Ruch of the earth movement may be attributable to spring <br />activity, although undercutting contributes to erosion <br />and slumping. This report recommends that mediate <br />steps be taken to stabilise the bank adjacent to the <br />house in order to prevent lose of the structure. The <br />report also recommends that surface water from <br />downspouts or other sources not be permitted to <br />discharge on or above the slope._ <br />
