The spots above the 7350' <br /> elevation on the south side, where in 2013 some settling occurred,were inspected and showed no <br /> additional differential settling at this inspection and when compared with the 28 June 2018 <br /> inspection. The 2018 inspection indicated additional settling in these areas and as a result, TMI <br /> agreed to utilize drone surveying to quantify additional settling should any be observed. It appears <br /> that there has been no change in volume for either of the depressional areas in the past year. <br /> The spring discovered during the third quarter of 2011 was flowing at the time of the inspection. <br /> Flow appeared to be less than one tenth of a gallon of water per minute. <br /> No organic material removal was conducted. Flow from the underdrain system was observed <br /> at the time of inspection to be approximately one quarter of a gallon per minute. Surface drains <br /> showed no water flow. All fill has been placed and compacted. <br /> DRMS has no questions at this time. <br /> Best Regards <br /> Robin Reilley M.S.
