GEOTECHNICAL ENGINEERING STUDY Susan and Ttiomas Zakos E-10138 Au�ust 20, 2002 Pac�e 2 Tl�e purpose of this study was to explore t��e subsurface conditinns at the site and based on conditions encountered ro develop geotechnical recommendations for repairing or replacing the existing retaininc� wall on the narth side of the single-family residence. Specifically, our scope of services consisted of the following: • Assessing tlie condition oi the existinc� fill and native soils; • Providing retaining wall alternatives and desic�n recommendations, including drainage and bearing recommendations; • Determining depth to competent soils; • Provicfing site preparatio�, c�radinc� and eartl�w�rk procedures, inciuding details of fill placement and compaction; • Recuninien�iny slwit-lerin an� luny-tunii yroun�wal�r nianayernenl and erosion contro� measures; and • Conducting a visual assessment of slope stability. At the time our study was conducted, tlie existing residence, railroad tie wall, and our expioratory locations were approximate;y as shown on the Schematic Bori!iy Lecation Plan, Plate 2. Surface The subject site consists of an approximately 10,000 square foot irregular shaped residentiai lot located at 1011 — 39"' Street in Everett (see Plate 1 , Vicinity Mao). Tlie site contains an existinc� tliree-story singie-family residence constructed in 1989. The residence dayli�hts to the norU� at the top of an appro�cimateiy forty (40) foot high north- facing slope that descends from the north side of 39"' Street to the centarline of an undeveloped City of Everett road easement located at tlie toe of slope along tiie nortiiern properry line.
