Description: This restoration project will restore 2,170 lineal feet of straightened and denuded channel into a natural creek while still providing flood protection. This project is the second phase of a three phase project. The new alignment will allow the creek channel to have greater water retention during high flows.

Project limits are from Victoria Drive downstream to Boron Avenue.
