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.

These walls typically will retain fill that will
