The $791.00 fee and map are enclosed. <br />In 2009, Denver Water placed buttress material in both Howe Haller A and Howe <br />Haller B to stabilize the permanent reclamation slopes. Additionally, we placed Slope <br />Lining Material to control and reduce erosion along the slopes of both Howe Haller A <br />and Howe Haller B. Lastly, we installed a groundwater dewatering drain, or Mounding <br />Drain, along the east side of Howe Haller B to maintain and control groundwater levels <br />such that they do not adversely impact the adjacent property. <br />If further information is required, please contact me at 303-628-6669. <br />Sincerely, <br />4ie H.Bambei, Jr <br />f of Engineering <br />Enclosures <br />cc: Mike Miller, Denver Water <br />Michele K.
