As part of a broader effort to improve fish passage and watershed health, this project includes replacing an existing bridge with a new prefabricated structure and removing a nonfunctional fish ladder from the creek. Additionally, the creek channel will be enhanced to support habitat restoration. The work is expected to be completed by October 31, 2025.
