It is our unde►standing thal a single family residence with a daylight basement is planned to be developed on the prope�ty. A topagraphic survey of the property depicting the planned location and elevation oFthe residence is still being devcloped at the timc of this report. Site Conditions 'I'hc property (lax lot no. 005717001004020 wa: located on the east side of Chinook Drive to thc norih of thc residence and shop building located ut 5121 Chinook Drive in F.vcrep, Washington. The 031 acre rectangulaz lot measured approximately l40 feet east-west by 95 fcrt north-south. The lot slopes down to the northeast at an approximate inclination of 35 percent. A 3 to 6 foot high slope of fill soils has been grnded onto the south side of the lot from �ading on the adjacent lol to the south to level the adjucent lot Thc short slope segmcnt was at an approximatc inclination of')0 percent. Total elevation chan�e from the southwc�t down to the northcast comer was ebuut 40 fect. The south sic�e of the lot was primarily covercd with bleckberty vincs. There was a cluster of vcry large Alder trecs in thc southwcst comer of the lot and largc f r trccs ncar thc middle and southeast comcr of the lot. A thick ground cover of ivy and native plan�s covcr the n:st oC the lot. '1'herc was no stnnding or flowing water on the property. Therc were no existing improvcments on thc lot. Subsurface Conditions Subsurfacc conditions un the property wete inferred from visuul reconnais.sancc of the pmperty, a review of an applicahlc geologic map, and a series of 3 subsurface exploration piu cxcavated on the property. The cxploration pits were excavated using a small track mountcd backhoc. ll�c cxplomtion pits wcrc loggcd by a licensed geologist and immcdiatcly backfillcd. lhc exploration pits were lacated at the toe of the south fill slope at the west and cast comers of the lot and ncar the BGC, pllc 14267 209°1 Avenue NE Woodinvllle, WA 98077 (425) 273-5062 � ��, �•.
