HUM 254 Avenue Culvert Rehab Project
NOE - Notice of Exemption
The purpose of this Project is to improve drainage systems and reduce erosion to protect SR 254. The project is needed because the culverts are deteriorating resulting in insufficient drainage capacity causing roadway flooding and embankment erosion which will lead to the roadway failure. The final goal of the project is to replace seven culverts to protect SR 254 from road failure.
This project involves restoring seven existing culverts by adding scour protection and replacing, when necessary, to decrease future degradation with de minimis increase in fill. The project will not result in an expansion of the existing use.
