Document Description
The project is limited to four encroachments. Three encroachments are for water diversion from unnamed tributaries to the Van Duzen 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 other proposed encroachment is to upgrade a failing and undersized culvert. Work for this encroachment will include excavation, removal of the failing culvert, replacement with new properly sized culvert, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion.
