About

enlarged project map iconNedonna Creek currently flows through two culverts under U.S. 101 and the railroad. The culverts are in poor condition and need to be replaced.  

Culverts allow water to flow under the highway and help minimize flooding. If a stream or creek is flowing through, they also help with fish passage. 

We're removing the culverts and installing new structures. This will help with drainage in the area and allow Nedonna Creek to flow easily under U.S. 101 and the railroad.
