� E� � t �� �� i� B� I� Geotechnical Report I'ire Station No. 5 6801 Beverly Blvd. �verett, Washin�ton 1.0 INTRODUCTION This report prescnts the rrsults of our geoteclmical siudy for the proposcd replacemcnt of Pirc Station No. 5. The purpose of our study was to assist you and your con�ultant tcam by providing geotechnical recommendations for the design and construction of ihe new facility. Our work was performed in general accordance witl�. our September 5, 2000, letter of confirmation to Mr. Rory Galloway 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 replacemenl structure and associated facilities. 2.0 SITE AND PRPJECT DESCRIPTION The exisling Pire Station No. 5 is located al the southcast comer of Be� erly Boulcvazd and Madison Street, as shown in Figure 1. The existing fire station is located on a trapezoidal shaped parcel with frontage lengths of about 145 fect along Beverly Boulevard and 165 fcet along Madison Slreet. Tlte ground surface on the property slopes slightly do�m to the southeasL providing a G-foot elevation differential across the site. There is a two foot high, cor.cretc retaining wall adjacent to the east wall of the building, provide grade separaticn Gom an zdjoining parking lot lo the erst. Fire Station No. 5 is located in a residential ncighUorhood of single-family dwcllings. Thc neighboring structures are typically one or two storied, wood framed construction with basements. Because the existing fire station has severe access constraints that make ceRain vehicular operations unsafe, four of the single family dwellings tliat were located souAi of the fire station were acquired to pemiit the replacement facility to be constructed over an expanded fi�otprint. The layout of the ne�v facility, superimposed over that of the existing site structures is shown on Figure 2. The footprint of tlie new building will extend furtlter south than the existing structurc. The new building footprint does not extend over any existing residential structure with a basemenL With lhe new properiy acquisition, the land area of the fire slation nearly lriple to about G7,000 square feet. The new configuration will provide Qie fire station will a frontage length of about 285 feet along Beverly Boulevard. The existing Fire Station No. 5 and the single-family residential dwellings within the project area will be demolished in phases to permit construction of a new 11,000 square foot facility. The new facility will be a high-bay, one-slory structure with a mezzanine level. The finished tloor elevation of the facility will be set at aUout Elevation 41 G feet. No basement is planned.
