7.5 Channel Adjustment Processes Narrative  
  This reach has historically been encroached, straightened, and armored. The inability to widen or adjust planform has caused this reach to continue to incise, leading to a stream type departure from C to F. The banks remain scoured after large storms, like T.S. Irene and the July 2014 floods, over-topped its banks. This reach will remain in stage II until it is able to widen and adjust planform beyond the bank armor.
