Geotechnical Consultants V1400140th Avenue N.E. mallikkmik Bellevue, Washington 98005 (206) 746 -8020 30 October 1987 W -5437 Mrs. Akiko Shimatsu 427 S.W. 154th Street, Apt. 5 Seattle, Washington 98166 Subject: Field Exploration and Preliminary Geotechnical Assessment Southcenter Parkway Commercial Development Site Tukwila, Washington Gentlemen: We are writing this letter to provide our preliminary geotechnical assessment of subsurface conditions, foundation considerations and site preparation recommendations for the above referenced project. The project site is located along Southcenter Parkway in Tukwila in an existing, nearly level, open field adjacent to a residence at 16813 Southcenter Parkway. The following paragraphs present our general assessment of subsurface conditions, foundation considerations, and site preparation considerations for the subject parcel. Subsurface Conditions Three borings were advanced at the project site, using hollow -stem auger techniques. Boring logs for these borings are enclosed to this letter.The approximate location of the explorations accomplished for this study are shown on the Site and Exploration Plan, enclosed with this letter, which also presents the proposed building outline and pertinent site physical features. Detailed descriptive logs of the borings are attached with this letter. We have prepared a generalized subsurface profile which illustrates our interpretation of subsurface conditions across the site. Boring B -1, advanced near the eastern property margin, indicated some loose to medium dense zones of sands, silty fine sands, and fine sandy silts underlain at depth by very stiff to hard silt strata. At the location of boring B -1 along the Mrs. Akiko Shimatsu 30 October 1987 W -5437 Page 2 eastern property margin, no indication of organic silt or peat were disclosed. Conversely, along the western property margin adjacent to the steep slope to the west, a continuous fiberous peat layer was disclosed on the order of 11 feet which was overlain by loose sands and underlain by the hard silt layer. Boring B -3 was advanced near the center of the proposed building, and indicated the peat lens was pinching out in thickness towards the east. The peat thickness was on the order of some 3 feet at the location of boring B -3. Foundation Considerations Based on the results of our subsurface exploration program, spread footing support of the proposed structure either on structural fill or directly above the native materials is not recommended to the potential for high differential settlements due to the variable thickness of the peat soils and their highly compressible nature. We recommend the building and floor slab be supported on driven piles founded in the hard silts present below the site. Due to the relatively lightly - loaded nature of the structure, driven timber piles may be an economical pile type. Driven timber piles with 8 inch penetrating at least 5 feet into the hard silt layer may be designed for a maximum allowable compressive capacity of 25 tons each. The depth of the pile tip penetration below existing site grades would be between 50 feet to 35 feet based on existing available information. Some variation in the depth to the bearing horizon may occur at locations distant from those explored. Site Preparation We understand project plans call for the placement of some 5 feet of fill to raise site grades to prevailing grade along Southcenter Parkway. Mr. Schofield has provided us a description of a potential borrow source for fill soils on the project site. If fill placement is to be accomplished during wet weather, we would recommend only the granular portions of these soils available from the nearby parcel be used for fill. If the fill can be placed and compacted during dry weather, the inclusion of finer - grained soils may bc! feasible. We would recommend if at all possible, that only granular soils be used within the upper 2 feet in proposed parking areas. • Mrs. Akiko Shimatsu 30 October 1987 W- 5437 Page 3 Below that depth, and within the building area, finer - grained soils could be used if weather conditions permit. Any fill placement along the western property margin, or above organic soils or peat deposits, will initiate substantial settlement. As a rule -of- thumb, long- term settlements over extensive peat deposits may approach as much as half the thickness of the fill placed. Our detailed settlement evaluation is presently underway. In a general sense, however, on the order of half of the total settlement would likely occur within the first six months after fill placement, and the remainder extending over a period of some 20 years or more. For this reason, it appears advantageous to place the fill on the project site as soon as possible. Surcharge techniques would accelerate the settlement response of the site soils, but surcharging is not commonly applied to parking areas. A staged fill placement scheme, whereby fill intended for the eastern portion of the project site is temporarily placed above the final fill along the west property margin, would improve the long -term performance of settlement- sensitive structures constructed above the organic soils. Construction of settlement - sensitive pavements or structures should be deferred as long as possible. Steep gradients should be used for buried utilities if gravity flows are to be maintained. We trust this letter is sufficient for your needs. Should you have any questions regarding this letter or other topics, please feel free to call at your earliest M convenience. `F J.
