The Watershed Company• EAIBlumen June 2012 4.5.2 Replacement Site Existing Conditions The Replacement Site is an undeveloped area of forest and other vegetated areas. No hazardous materials or wastes are anticipated to be located the site. A review of the Ecology Cleanup Site Database was conducted as part of this analysis to determine whether any hazardous materials/wastes sites have been identified in the vicinity of the Replacement Site and no known cleanup sites are located in the vicinity of the site. Three cleanup sites were identified approximately 0.50 miles to the east and southeast of the Replacement Site. The closest site is located approximately 0.45 mile east of the site (AA Rentals site located near 119th Avenue SE and 110th Street SE). The electrical substation to the immediate south of the site is not identified as a hazardous materials site. Environmental Consequences As described above,the Replacement Site contains no known hazardous materials/wastes and no hazardous materials/waste cleanup sites are located on or in the vicinity of the site. Therefore,no hazardous materials/wastes impacts area anticipated as part of the Proposed Action. 4.5.3 Mitigation Measures The Proposed Action would not result in any impacts associated with hazardous materials/wastes, and thus mitigation measures are not necessary. 4.6 Topography and Soils The elevation on the Replacement Site ranges from 477 to 480 feet AMSL (above mean sea level), and the Conversion Site ranges from 475 to 481 feet AMSL (GoogleEarth). Both sites are generally flat, although the replacement site slopes downhill slightly to the east and south, consistent with the locations of wetlands and the north-south running ditch along the east property line. The Conversion Site and the Replacement Site are classified by USDA's Soil Survey of Snohomish County Area, Washington (USDA 2012) as Alderwood-Urban land complex,2 to 8 percent slopes. This complex is a mix of soil types with varied characteristics,but are all formed over glacial till. Specific geotechnical investigations would be completed by the City if needed for the very limited development anticipated on the Replacement Site. The City conducted the necessary geotechnical studies prior to the fire station and road development on the Conversion Site, and constructed the facilities consistent with those studies and any design recommendations.
