The purpose of this letter is to transmit our findings on the subsurface soil and ground water conditions and to make recommendations.for bearing capacity. We understand that the developments are to consist of two (2) adia" cent single family residences. One residence is to be built at 303 7th Avenue and will be a two (2) story, wood -framed home with a garage located under the structure. This residence will utilize spread footings with crawlspace and slab -on -grade in the garage area. The second residence is to be built at 705 Alder Street and will be a one (1) story, wood framed home with a daylight basement. This residence will utilize spread footings with crawl.space and slab -on - grade in the basement area. No construction or survey plans were available. We should be en- gaged to review the project plans when they are available to pr o- vide specific recommendations. I CASCADE GEOTECHNICAL March 2, 1989 Job No. 893-2G Sands Construction Page 2 SITE DESCRIPTION The subject site is located on the northeastern corner of the intersection of 7th Avenue West and Alder Street, Edmonds, Washing- ton and is situated approximately one half mile east of Puget Sound. Single family residences are located to the north and east. The two lots are 6600 square foot, adjacent rectangular parcels. The site slopes downwards towards the west and has an approximately thirty (30) foot elevation difference between 7th Avenue West and the eastern property line. At the time of our visit, considerable excavation and filling had extensively changed the original site topography. Th e site was originally used for a single-family residence with a basement that was recently demolished. The eastern lot was excavated resulting in a flat bottomed cut with three (3) to ten (10) foot high near - vertical cuts. The excavated soil was placed on the western lot mantling the pre-existing ground. Most of the property has been cleared of trees and other vegetation except on the northern edge where bushes were present. Areas of discontinuous standing,water were observed in the excavation on the eastern lot. SOIL CONDITIONS Subsurface conditions were determined from six (6) test pits using a tracked hoe located within or adjacent to the proposed resi- dences. Soil types were described and classified in the field I 11 00 CASCADE GEOTECHNICAL March 2, 1989 Job�No. 893-2G Sands Construction Page 3 using the Unified Soils Classification System. The test pit lo- cations are presented in Appendix A. On the western lot, uncontrolled, fill consisting of silt and sand with minor organics and bui lding debris ranged f rom twenty-one (21) inches thick in the southern section to eight (8) and six (6) feet thick in the central and northern sections were found in test pits 1, 5 and 6. A one (1) to two (2) foot thick layer of a dark brown topsoil with minor organics was found -to underlie the uncontrolled fill. Beneath the uncontrolled fill and the topsoil are a brown, to blue -gray medium de nse sand with minor gravel and trace silt or a brown -gray to blue -gray stiff silt. The sand was found in the northern section and was first encountered six (6) feet below the existing ground. The silt' was found in the central and southern sections and was first encountered eight (8) feet and forty-three (43) inches below the existing ground, respectively. �The central section was the approximate site of the demolished residence. In the eastern lot, blue -gray stiff silt was found underlying the existing ground in the excavated cut. The one' exception was found in test pit 3 where forty (40) inches of uncontrolled fill was found over the blue gray silt. No ground water seepage was observed except in test p it 3 where weak ground water seepage was observed at two (2) feet below exist- .ing ground level. CONCLUSIONS AND RECOMMENDATIONS Based upon this test pit data, we conclude that the site to be suitable for the proposed residences, if our recommendations are followed. I I I I I I I I I I I I I I CASCADE GEOTECHNICAL March 2, 1989 Job No. 893-2G Sands Construction Page 4 Considering only bearing capacity, the brown to blue gray sand and silt are suitable to support spread footings designed to a maximum safe bearing value of 2000 psf if the soil is firm, undis- turbed, free of organic material and does not become wet prior to concrete placement. We recommend that all building areas on the western lot and the western edge on the eastern lot should be stripped of uncontrolled fill and topsoil. Any standing water in the eastern excavation should be drained or removed by pumps. Softareas within the foun- dation areas should be removed and replaced with crushed rock. When a dry, non -yielding subgrade is established, the concrete may be placed. We should be engaged to inspect the foundation excava- tions prior to placing the concrete to confirm suitable soil con- ditions. It has been our pleasure working with you on this report. Should you have any questions regarding this letter or require further services, please feel free to contact us at any time. Sincerely, CHNICAL CASCADE GEOTE ge E. Lamb, P.E.
