Geotechoical Report Fire Station 1Vo. 5 6801 Beverly Blvd. Everett, Washington 1.0 INTRODUCTION This report presents the tesults of our geotechnical study for the proposed replacement of Fire Station No. 5. The puipose of our study was to assist you and your consultant tcam by providing geotechnical recommendations for the design and construction of the new facility. Our work was performed in general accordance with our September 5, 2000, letter of confirmation to Mr. Rory Gallowey of G-Logics. Our work scope included reviewing existing subsurface data, advancing seven exploratory borings to supplement the existing subsurface data, and performing engineering analyses to develop recommendations for the foundation design of the replacem:nt structure and associated facilities. 2.0 SITE AND PROJECT DESCRIPTIOIV � The existing Fire Station No. 5 is located at the southeast corner of Beveriy Boulevard and Madison Streec, as shown in Figure 1. The existing fire station is located on a trapezoidal shaped pazcel with &ontage lengths of about 145 feet along Beverly Boulevard and 165 feet along � Madison Street. The ground surface on the property slopes slightly down to the southeast, providing a 6-foot elevation differential across the site. There is a two foot ;iigh, concrete 1 retaining wall adjacent to the east wall of the building, provide grade sepazation from an adjoining pazking lot to the east. Fire Station No. 5 is located in a residential neighborhood of single-family dwellings. The ' neighboring structures aze typically one or two storied, wood framed construction with basements. Because the existing fire station has severe access consuaints that make certain � vehiculaz operations unsafe, four of the single family dwellings that were located south of the fire station were acquired to permit the replacement facility to be constructed over an expanded , footprint. The layout of the new facility, superimposed over that of the existing site shuctures is shown on Figure 2. The footprint of the new building will extend further south than the existing structure. The new building footprint does not extend over any existing residential structure �:�iih a basement. With the new property acquisition, the land azea of the fire station neazly fiple to about 67,000 squaze feet. The new configuration will provide the fite station will z. frontage length of about 285 feet along Beverly Boulevard. The existing Fire Station No. 5 and the single-family residential dwellings within the prcject area will be demolished in phases to permit construction of a new 11,000 squaze foot facility. The new facility will be a high-bay, one-story struct�re with a mezzanine level. Che finishc�l floor elevation of the facility will be set at about Elevation 416 feet. No basement is planned. A 6foot
