Clarification. The impact is 170 of impact? And the plan is to self mitigate from the SW
discharge? IS A the discharge from the BMP? If so, what is B? And C discharges to the
wetland.
At minimum, a "french drain" type fill/system should be utilized for the 170 ft of fill.
It may be a better idea to create the step down throughout the length of the new channel,
rather than waiting to the very end. Typically you end up with a staircase type step down. See
sheet 4 of 10, rather than a single drops over 30 ft, have more variable number of drops
through out the reach which should reduce a major stepped down at the end. .
