State Route 174 Culvert Repair Project
NOE - Notice of Exemption
The project is limited to the repair of 10 existing corrugated metal pipe (CMP) culverts using alternative pipe liners (APL). APL can consist of either high-density polyethylene (HDPE) liner or cast in place (CIPP) liner, which is the process of installing a thin, flexible liner to the walls on the inside of the existing culvert. Rock slope protection will be added to the base of the culvert outfalls where necessary.
