Mr. Tom Schreiner, Division of Minerals and Geology <br />March 23, 2005 <br />Page 11 <br />~~ <br />CIVIL RES~JURCES,LLC <br />Colorado Highway 85, building foundations, leach fields, shallow domestic wells, deep aquifer <br />domestic wells, or high production irrigation wells. (In the event of adverse mounding effects, the <br />applicant may want to consider the installation of French Drains in strategic locations.) <br />Modeling was performed for the fully reclaimed condition as presented in Section 4.3 of the Groundwater <br />Model Report and as discussed in Comment 16. Groundwater was modeled to mound approximately three <br />to four feet just east (under WCR 27) of the site. Therefore, groundwater levels may potentially rise to <br />approximately 20 feet below existing ground surface. This mounding will have a beneficial impact on local <br />shallow wells. There were no significant Post-Construction impacts predicted by the model for the southern <br />and northern margins of the site. A slight shadow of approximately 2 feet was calculated under Highway 85 <br />and no wells are located within the shadow. <br />27. Please provide a specific map or exhibit showing the locations of all existing and proposed <br />water monitoring locations, whether they 6e wells or peizometers, whether they be on-site or off- <br />site. Please be su-e to include the locations of the two (2) control points along the South Platte <br />River. The specific monitoring locations should also be identified according to ownership and <br />construction data such as diameter, total depth, and existing depth to groundwater. Although not <br />required, the Division recommends the applicant also include a description of the location and <br />horizontal distance to any other groundwater users that may cause interference of the monitoring <br />well. The location of the 2 control points along the South Platte River should also be <br />Refer to the attached Monitoring Well and Boring Location the approximate location of the monitoring <br />devices and the depth each piezometer was completed to. <br />28. Please revise the table of existing water monitoring data to include all baseline water monitoring <br />data collected to date. The Division will require a fu1112 months of baseline water level monitoring <br />prior to initiation of de-watering activities. In the event a fu1112 month set of data is not available, <br />the applicant will need to commit to providing the remaining data needed prior to initiation of de- <br />watering activities at the Fulton Lakes Resource. Please respond. <br />See Figure 6-Ra for the updated groundwater data and Figure 6-R for a graph of the data. The data as <br />discussed in Comment 15 will be reported to the Division on a quarterly basis and on request. Presently 10 <br />months of data has been compiled and will continue to be updated. <br />Thank you for taking the time to meet with us and review the groundwater model. We believe our response <br />information satisfies your comments, however if you have additional questions please do not hesitate to call <br />meat 303.833.1416 ext. 2. <br />Sincerely, <br />CIVIL R OUR S, LLC <br />Andrew Rodri ez, E.I.T. <br />Water Resou s Engineer <br />
