±½ mile grid beginning at the river and extending southwesterly fro m three to five miles. <br />Wells will be located within the respective shaded area shown on the map attached as <br />Exhibit A. Depth to groundwater will be measured in each well and converted to M.S.L. <br />elevation using the surface measurement. River water elevat ions will also be obtained <br />where the northerly edge of the study area meets the Rio Grande. Davis Engineering <br />proposes to use GPS equipment to accomplish the surveying. Ultimately, the measured <br />river and groundwater elevations will be mapped and groundwa ter contours will be <br />plotted. Contour configuration will then be used to map the location of the hydraulic <br />divide. <br /> <br />FINAL PRODUCT <br /> <br />The final product will consist of a GIS based map, compatible with RGDSS GIS <br />mapping, containing the location of all wells i n which the groundwater level was <br />measured. The well locations will be in NAD 1983, UTM coordinates, Zone 13 N. <br />Using measured groundwater levels at the wells, a groundwater level contour map will be <br />prepared on the GIS map. Within the hydraulic divide study area, the hydraulic divide <br />will be drawn using the groundwater contours to define the divide between the Closed <br />Basin and the Rio Grande . <br /> <br />PROJECT SCHEDULE <br /> <br />The period during the year in which well pumping stops and the groundwater levels <br />stabilize i s January through March. During February and March of 2007 , wells will be <br />selected and groundwater level measured. Survey of selected well locations and <br />measuring point elevations will begin during the groundwater level measuring process <br />and be completed within ±2 months thereafter. Mapping will be initiated immediately <br />and completed within ±1 month after all field data is collected. Assuming authorization <br />to proceed is received by February 1, 2007, all work will be completed by June 30, 2007. <br /> <br />COMPENSA TION <br /> <br /> <br />Davis Engineering Service, Inc. proposes to perform the SLV Groundwater Level Study <br />as an independent contractor furnishing all labor, materials, equipment, and <br />transportation not to exceed $6 0,000. Actual charges will be computed based on time <br />and cost at $100/hour . <br /> 3 <br />
