Document Description
The project is limited to three encroachments. Two proposed encroachments are to upgrade failing and unpermitted stream crossings. Work for these encroachments will include excavation, removal of the failing crossings, replacement with new properly sized crossings, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion. The other encroachment is to implement interim remediation measures to the overspill of an unpermitted on-stream reservoir on an unnamed tributary to Ellison Creek. The Permittee shall retain a licensed engineering geologist to perform an updated stability analysis of the dam and follow professional recommendations for upgrading or decommissioning the reservoir. The impoundment is formed by a 15- to 20-foot tall earthen dam that lacks a formal spillway; instead water overspills through a deeply incised channel to the right of the embankment, around the downstream slope face and down the hillslope where it meets the original stream channel. Water was also observed seeping from below the toe of the downstream slope face. Concrete, corrugated black plastic flexi-pipe, black plastic lining sheets, yellow plastic conduit, black plastic irrigation line, and all other refuse shall be removed from the stream channel, riparian area downstream of the impoundment and any location within 150 feet of the high water mark of the waters of the state and relocated to an authorized waste management facility.
