Document Description
This Agreement relies on the Notification materials and a CDFW site inspection by Environmental Scientist John Herrera on January 9, 2019. The project is limited to five (5) encroachments (Table 1). One encroachment is for water diversion from an unnamed tributary to Feliz Creek. Water is diverted for irrigation only. Work for the water diversion will include use and maintenance of the water diversion infrastructure. Diverted water is stored in Reservoir-1 (Table 1) and additional storage tanks. The second proposed encroachment is to enhance a spillway of an existing reservoir (Reservoir-1), with an 18” diameter outlet connected to waters of the State, that serves as storage for the POD. Work for the spillway enhancement will involve removal of large rocks and material from existing outlet ditch, excavation of ditch banks to 2:1 slope, lining ditch with appropriately sized and embedded rock, and application of erosion control measures to minimize surface erosion. The third proposed encroachment (STX-A) is to install a rock armored low water crossing on an existing road without a crossing facility. Work for this encroachment will involve excavation, construction of the armored crossing following construction details in the Notification, backfilling and compaction of fill where necessary, and rock armoring as necessary to minimize erosion. The fourth proposed encroachment (STX-2) is to repair and enhance an existing stream crossing that lacks armoring, is misaligned, not set to grade, and includes a secondary undersized parallel culvert that is obstructing stream flow. Work for this encroachment will include excavation, removal of the smaller parallel culvert, properly re-aligning and setting the larger 18” culvert to grade, backfilling and compaction of fill, and rock armoring as necessary to minimize erosion. The fifth proposed encroachment (STX-5) is to upgrade a failing and undersized stream crossing functioning as an outlet for an on-stream pond. 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.
