Tryon Creek Fish Passage Improvement Project

Sewer and Stormwater
Environmental Services is designing stream and habitat improvements underneath the new Boones Ferry Bridge. This project will help support healthy habitat for fish and wildlife by allowing fish to reach upstream areas of the Tryon Creek State Natural Area and Marshall Park.
Design is currently underway. Construction is expected to take place in the late spring/early summer of 2023..

In the spring of 2022, Environmental Services completed the Boones Ferry Bridge Project.  This project removed an undersized culvert in Tryon Creek and replaced it with a new bridge. The new bridge created and restored connections for fish, wildlife, and people. Now that Tryon Creek is flowing freely, crews need to return to ensure that the creek is passable for fish species moving upstream to the new habitat areas opened up by the bridge project.

Project Area

The project is located in Tryon Creek where it passes underneath the new Boones Ferry Bridge.

What's Happening Now

Engineers and designers have reached the 60% design milestone for this project. The project team is now focused on completing the design work over the coming months, as well as applying for land use permits.

Crews will be visiting the area over the coming months to conduct survey activities, take soil samples, and other investigative activities.

You may see paint markings, stakes, and small flags in the ground identifying the locations of utilities and sewer and/or stormwater infrastructure. Different marking colors identify the types of utilities that have been located. If you are interested in learning more about what each color means, or for more information on the survey and inspection process, please visit the Pre-Construction Activities page.
