- Document Description
- This Agreement relies on the Notification materials and a desk review without a CDFW site inspection. The project is limited to 1 encroachment. The proposed encroachment is to upgrade an undersized stream crossing. Work for this encroachment will include excavation, removal of the failing crossing, replacement with new properly sized crossing, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion. The crossing currently has an undersized 18-inch diameter culvert which will be replaced with a culvert appropriately sized to pass a 100-year storm event. Permanent culverts shall be sized to accommodate the estimated 100-year flood flow [i.e. =1.0 times the width of the bankfull channel width or the 100-year flood size, whichever is greater], including debris, culvert embedding, and sediment loads.
