c. BRL provided revised designs for the lower (1 %) segment of the East Clean
Water Diversion Ditch as requested. The previously approved design for the
ditch was a triangular configuration. The revised design indicates that the
channel will be trapezoidal, but the design for the trapezoidal channel is based on
a bottom width of 0.00 ft. Please revise the design information for the East
Clean Water Diversion on page Volume Xl, App. B -78 to either specify a
triangular channel, or provide a bottom width and revised design
information for a trapezoidal channel.
BRL: The design for the 1.% segment of the clean water ditch is for a Triangular
channel. Please see revised page Volume XI, App. B -78
