There have been no dramatic upward fluctuations for almost <br />exactly one month (5-11-15 thru 6-8-15) and water levels have held between 14.0' and 14.4' below the <br />top of casing ("TOC") even though we have had this tremendous amount for rainfall in the area and <br />the ground is saturated. I have also been in contact with both Levi Kirby and Lyle Gurley on the east <br />side of Brighton Rd. and who both have structures below grade (a basement area and a well vault) and <br />although the groundwater has risen, no pumping has been required and no injury to these structures <br />has occurred. This tells me that indeed the drain is working as designed and is keeping the <br />groundwater "at bay" in the areas of concern even in these worst of possible groundwater conditions. <br />Please contact me if there are any questions or concerns you may have with this submittal for the <br />referenced operation. <br />Sincerely, <br />Rob Laird <br />Resource Manager AF & Report <br />✓ VIOLATIONS: MV 2009 016 <br />cc: file <br />
