The project is limited to 12 encroachments. Two encroachments are for water diversion from spring and surface waters impounded into ponds. Water is diverted for domestic use and irrigation. Water diversion from Crimea Pond 1 which is a 100,000-gallon spring fed reservoir appears mostly stable, but CDFW observed a superficial
settling crack in the earthen embankment. The pond is located on APNs 218-081-004 and 218-081-003 has an existing 24” culvert spillway and water is present year-round. Work includes adequately rocking the outlet and vegetation and debris clearing of the spillway inlet. Pond 2 received upslope surface flow via in inboard ditch and contains 2,000,000 gallons of storage capacity with a 24” waterman culverted outlet with a downspout which flows into a T dissipater and lastly into an inboard ditch. CDFW CE recommends including adequate erosion control e.g., rip rap rock to dissipate flow
energy at the outlet receiving inboard ditch. Work for these water diversions will include use and maintenance of the water diversion infrastructure. The 10 other proposed encroachments are to upgrade or decommission failing and undersized culverts. Work for these encroachments will include, removal of the existing culverts, replacement with new properly sized culverts or rock fill fords, decommissioning, excavation, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion.
