The Site is currently owned by the City of Stockton Redevelopment <br /> Agency (RDA), which refers to the Site as "Parcel 2A". The Site currently consists of relatively <br /> t flat, fallow land and is mostly undeveloped except for the Delta View Apartments (formerly the <br /> Delta Gateway Apartments) located on the western portion of the Site. The Stockton Deep <br /> Water Channel, Weber Avenue, and an office building complex are located north of the Site. <br /> ' The Mormon Slough, a children's museum, Work Net building, and State DMV Building (under <br /> construction) are located to the southwest, south, and east of the Site, respectively. <br /> ' During a December 2, 2002 meeting with the RWQCB-CVR, environmental management of the <br /> Site was divided into three operable units (OUs): L&M OU; Unocal OU (UOU); and Morton OU <br /> (MOU). The L&M OU was established to direct investigations in the area south of West Weber <br /> Avenue, west of the midline of the former Harrison Street, east of North Edison, and north of <br /> former Main Street (Appendix A). This OU includes monitoring wells MW-9, 2AMW-12 through <br /> 2AMW-14, MW-16 through MW-35, MW-41 through MW-52, MW-54, MW-55, and dual phase <br /> ' extraction (DPE) wells DPE-1 through DPE-13; the DPE network used to comprise MW-40 <br /> which was converted to a DPE well permanently during the second quarter 2007 but was <br /> abandoned during the fourth quarter 2008 due to the Unocal excavation activities. The UOU <br /> was established to direct investigations from West Weber Street south to the former Main Street <br /> and from the midline of the former Harrison Street east to Lincoln Street. The UOU includes <br /> monitoring wells MW-3, MW-7, MW-37 and MW-38. The MOU was established to direct <br /> ' investigations from the middle of the former Main Street down to the southern boundary of <br /> Parcel 2A and from the midline of the former Harrison Street east to Lincoln Street. The MOU <br /> includes monitoring wells MW-06R 2BMW-1, and 2AMW-15 and is currently under <br /> redevelopment. Currently, oversight of environmental management responsibilities of the L&M <br /> OU is retained by Stantec on behalf of CEMC and COP, and oversight of the UOU and MOU is <br /> performed by Wallace Kuhl Associates (Wallace-Kuhl), on behalf of the RDA. <br /> 1 <br /> ' I:\Td.teATW Sto&Wn(Pa¢ l PA 415)\Reports\oMRt 010L Q10\8Q10QSSRQRSRQMR Stoc n_FINALAtl 1.2 <br />
