Harlan Way Culvert Replacement Project

NOE - Notice of Exemption
Project Applicant
City of Blue Lake

Document Description
The purpose of this project is to replace a failed 36-inch diameter culvert, crossing Harlan Way, located on an unnamed intermittent stream. Multiple repairs have been completed in the past with little to no effect. The bottom of the 36-inch diameter corrugated metal pipe (CMP) that conveys drainage under Harlan Way has corroded away, allowing drainage to flow through the surrounding roadway sub-grade, carrying away sediment, creating voids and causing roadway failures in the form of sinkholes. The project would replace the existing 36-inch diameter corrugated metal pipe (CMP) under Harlan Way,restore the roadway, implement rock slope protection and energy dissipation at the outlet, and mitigate project impacts to the stream channel and associated riparian area at a 2:1 ratio.
