Farmington Groundwater Recharge Program STC Work Plan—Kautz Site <br /> 2.1.2. Conduct Reconnaissance Level Biological and Cultural Assessments <br /> Preliminary assessment of the site is necessary to identify potential cultural and biological <br /> resource considerations. Before field investigation activities commence, biological and cultural <br /> resource surveys will be performed by qualified USACE staff. Findings will be documented and <br /> reviewed prior to field investigation activities. <br /> 2.1.3. Acquire Necessary Permits <br /> Drilling and well construction permits will be obtained from the San Joaquin County <br /> Environmental Health Department (the County) prior to commencement of drilling activities. A <br /> representative from the County will likely be present to inspect backfilling of soil borings and <br /> monitoring well grouting activities. <br /> 2.1.4. Determine Borehole Locations <br /> A total of ten boring locations will be sited in equally spaced increments throughout the site <br /> (Figure 3). Locations will be surveyed with the use of a survey quality global position satellite <br /> (GPS) receiver. <br /> 2.1.5. Mark Locations of Buried Utilities <br /> An overhead power line energizes the on-site well. The line comes from a three-phase main line <br /> along Locust Tree Road. An underground network of small diameter PVC irrigation piping may <br /> exist at the site. Prior to the boring investigation and monitoring well drilling, MWH will <br /> contact Underground Service Alert(USA)to insure utility clearances at the site. <br /> 2.1.6. Identify Potential Water Sources <br /> An underground aqueduct, originating from the Mokelumne River, is located approximately '/4 <br /> mile south of the site. One agricultural well is located on site (Figure 2). NSJWCD currently <br /> has a temporary above ground PVC conveyance line from the aqueduct to the proposed site, <br /> however, the line can handle only very small head pressures. No ditches, culverts or other canals <br /> were observed during the initial site walk. The former vineyard may have been watered by an <br /> underground network of PVC piping. <br /> MWH 2-2 July 2004 <br />
