March 30, 2012 <br />3 <br />2.0 Critical Construction Periods <br />2.1 Removal of All Organic Material and Topsoil <br />Topsoil and organic material removal activities were not conducted during the quarter. <br />2.2 Placement of Underdrainage Systems <br />The underdrainge system was completed in the first quarter of 2010; additional work on this system is <br />not anticipated. During the time of the inspection, the water flow from the underdrainage system was <br />estimated to be 1 % gallons per minute. <br />2.3 Installation of Surface Drainage Systems <br />Both the north and south surface drains were inspected (photographs 2 and 3). No construction <br />occurred on these drains this quarter. At the time of inspection there were approximately % gallons per <br />minute of water flow from residual snow melt running in both surface drains. This water added to the <br />flows seen at the area where the underdrain water comes to the surface. <br />
