Savage Water Diversion and Stream Crossings Project (Streambed Alteration Agreement No. 1600-2018-0531-R1)

Savage Water Diversion and Stream Crossings Project (Streambed Alteration Agreement No. 1600-2018-0531-R1)

The project is limited to 11 encroachments (Table 1). Two encroachments are for water diversion from unnamed tributaries to Eubank Creek. Water is diverted for domestic use and irrigation from storage for cannabis cultivation. Work for the water diversion will include use and maintenance of the water diversion infrastructure. The nine other proposed encroachments are to upgrade or decommission failing and undersized 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.
