Sulphur Creek Stream Crossing Extension Project

NOE - Notice of Exemption
Document Description
The project is limited to the extension of an existing 48-inch corrugated metal pipe (CMP) culvert within an intermittent stream channel that was damaged during the Zogg Fire, as well as the installation of additional road surface. 20-feet of additional 48-inch CMP will be placed in the upstream portion of the channel and connected to the existing CMP with a band. New CMP will be backfilled with 2-inch minus base rock and compacted every 12-inches. Approximately 150-feet of fill material will be used. The final roadway crossing will be 15-feet wide. Straw waddles will be utilized to minimize erosion and sedimentation of the stream channel during project activities, and loose straw will be placed over disturbed ground. An excavator and jumping jack compactor will be used from top-of-bank to conduct project activities.
