Auto Mall Associates E-2976 May 16, 1986 Page 2 Based on our discussions with you and your architect, we understand that it is planned to construct two tilt -up structures and a self serve gasoline/convenience store on the site. Anticipated loads are on the order of 2 kips per lineal foot for perimeter walls, 60 kips for isolated columns and tw,) hundred fifty (250) psf for slab loads. Cuts and fills are anticipated to be up to eight feet in thickness. If any of the above design criteria change, we should be consulted to review the recommendations contained in this report. In any case, it is recommended that Earth Consultants, Inc. prov_.9e a general review of the final design. SITE CONDITIONS Surface The site is located on the southside Everett Mall Way as shown on the attached Ex:.sting site conditions are presented Lo,:ation Plan. of the 300 block of SE Vicinity Map, Plate 1. on Plate 2, Test Pit Generally, the site slopes from east to west with overall relief on the order of twenty (20) feet. An existing manufacturing building with paved parking is located along the western margin of the site. A gutted single-family structure is preoent along the north center of the site. The eastern and southern portions of the site are covered by typical native forest. The site is bordered by undeveloped properties. Subsurface The site was explored by excavating eight test pits at the locations shown on Plate 2. Please refer to the test pit logs, Plates 4 through 7, for a detailed description of the conditions encountered at each location explored. A description of the field exploration methods and laboratory testing program is included in this report following the Discussion and Recommendations section. The following is a generalized description of the subsurface conditions encountered. Our test pits encountered relatively uniform subsurface conditions beneath the site. Generally, the site is immediately underlain by from two to four feet of loose silty sands. Beneath this surficial mantle, all of our test pits encountered dense granular till soils to the depths explored. Due to existing pavements, no test pits were excavated along the western margin of the site. ECI anticipates that grading Earth Consultants, Inc.
