This restoration project will restore 2,450 linear feet of straightened and denuded channel into a natural creek while still providing flood protection. The new alignment will allow the creek channel to have greater water retention during high demands.

Human elements include the creation of a bicycle/pedestrian path and pedestrian bridge.
