The site is located on the northwest comer of 19th Avenue SE (Highway 527), and 100th Street SE in the city of Everett, as shown on the Vicinity Map in Figure 1. You have retained us to perform a geotechnical engineering study to evaluate the site for the proposed structure and parking areas. We have been provided a copy of a topographic survey dated October 22, 1996, by Barghausen Consulting Engineers, Inc., and a preliminary grading, storm drainage and water quality treatment plan with the proposed location of the building, dated February 28, 1997, by Barghausen Consulting Engineers, Inc. The preliminary design shows the building footprint area toward the west end of the lot, as shown on the Site Plan in Figure 2. The site will be accessed from 19th Avenue SE on the northeast comer of the site and from 100th Street SE on the mid-southem portion of the site. We understand the building will be slab -on -grade construction and have a main floor finished elevation of approximately 570.3 feet (Project Datum).

Retaining walls, up to 25 feet high, are proposed for the northwest corner of the building and along the on -site storm water detention pond, in the southwest portion of the site. These walls typically will retain fill that will
