Document Description
This Agreement relies on the Notification materials and a desk review without a CDFW site inspection. The project is limited to seven encroachments (Table 1). Two encroachments are 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 according to the terms of this Agreement. Two proposed encroachments are to upgrade failing and undersized culverts. 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. Two encroachments are to decommission stream crossings by removing failing culverts and to implement stream restoration and revegetation. One encroachment is for stream restoration for a seasonal stream that has been rerouted around an unpermitted structure located within the Streamside Management Area and riparian setback.
