The approved design for Ditch 55, Stations 26 +00 to 37 +00, is presented in Exhibit 19(24)
pages 24 -26, and further described on page 2.05 -11a. The approved design shows the ditch
is trapezoidal, with a minimum depth of 1.6', bottom width of 3', 2:1 sideslopes, and 3" rip
rap lining. These design specifications were compared with the cross sections. The
constructed ditch is triangular, as opposed to the approved trapezoidal configuration, and
Division observations indicate that this section of the ditch has not been rip rap lined. The
table below summarizes the comparison of ditch depth and sideslopes to the approved
design. Values in red indicate that the ditch, as constructed, does not meet the minimum
requirements of the approved design for depth and sideslope (L /R consistent with cross -
sections provided).
