I Proposed Everett Hotel Property Environmental Site Characterization and Everett, Washington Remediation Recommendations I. SITE CHARACTERIZATION 1.0 PROJECT BACKGROUND/SITE DESCRIPTION The following report presents the results of environmental site characterization and provides recommendations for remediation for the subject property. Other reports previously prepared for this project are referenced in Section 2.3. This report does not duplicate the previous reports in their entirety, but provides an overview of the previous subsurface characterization work conducted for the site. 1.1 Location The subject property is located at the southeast corner of the intersection of ColbyAvenue and P P Y Wall Street in Everett, Washington (Figure 1). As depicted on the "Site and Exploration Plan," Figure 2, the site is rectangular in shape and encompasses an area of approximately 20,000 square feet. The site currently consists of an asphalt paved parking lot owned by the City of Everett. With the exception of some small planter areas along the west side and at the northeast corner of the property, the entire site is asphalt-paved. The property is bordered to the south by an office building (The Culmback Building, 3013 Colby Avenue), to the west by Colby Avenue, to the north by Wall Street, and to the east by an alley, beyond which is a building occupied by the Everett Police Department. The subject property was formerly occupied by the Allen Buick building, which was reportedly demolished in 1975. It is our understanding that redevelopment of the site as a hotel has been recently proposed. 1.2 Topography The topography of the site is relatively flat; however, its surface lies approximately 7 to 14 feet below Colby Avenue and Wall Street, which border the site to the west and north, respectively. Grade separation between these streets and the subject site is provided by retaining walls. As previously discussed, an alley borders the site to the east. At its north end (adjacent to Wall Street), the alley lies approximately 7 feet above the level of the parking lot. The alley gradually slopes down toward the south, becoming even with the ground surface of the parking lot approximately 40 to 50 feet south of Wall Street. Grade separation between the north end of the parking lot and the adjacent, higher elevation alley is provided by a cast-in- place concrete retaining wall.
