One boring each will be <br /> located in the proposed building pad area, the proposed pump island canopy area and the area of the <br /> proposed USTs. Soil borings SB-2 and SB-3 will be completed to a depth of approximately 20 feet <br /> bgs. Soil boring SB-1 will be completed to a depth of approximately 50 feet bgs. SB-I will be utilized <br /> to evaluate liquefaction potential for subsurface soils beneath the property because of shallow <br /> groundwater (7 to 10 fxt bgs). It is also recommended that a minimum of f...r groundwater <br /> monitorrmg wells be installed (MW-1, MW-2,aI MW- to evaluate if shallow groundwater beneath l <br /> the property has been impacted by offsite sources (refe to Table N, Surrounding Land Use). <br /> Item' Itcummeadatian y Ynrt'Cnsts° <br /> #of Borings 4 geotm hnicaVenviroamental borings Some additional job costs for liquefaction analysis <br /> 3 groundwater monitoring wells and groundwater monitoring well installation. <br /> I <br /> Analysis TPHg TPHd,TRPH Standard job costs.
