Document Description
The project is limited to three encroachments. One encroachment is for water diversion from unnamed tributaries to the Mad River. Water is diverted for domestic use and irrigation. Work for the water diversion will include use and maintenance of the water diversion infrastructure. The second proposed encroachment is to upgrade an undersized culvert spillway on an on-stream pond. Water is not diverted from the on-stream pond. The pond will be inspected by a licensed engineer to determine if the construction meets Humboldt County building codes and to determine if the embankment and spillway are appropriately designed. The third proposed encroachment is to upgrade an undersized culvert on a road stream crossing. Work for these encroachments will include excavation, removal of the failing culverts, replacement with new properly sized culverts, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion.
