Document Description
The project is limited to nine (9) encroachments (Table 1). One (1) encroachment is for the diversion of water from an unnamed tributary to the Mattole River. The diversion of water is for domestic use. Work for the water diversion will include use and maintenance of the water diversion infrastructure. One (1) encroachment is to remove an unpermitted diversion and associated infrastructure. Work for this encroachment will include cutting pipes emanating from the channel, the removal of a tank located on the channel bank, and recontouring and stabilization of the channel bank. Three (3) 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. One (1) encroachment will include the removal of partially buried refuse within a class III stream and the recontouring and stabilization of the channel. Two (2) encroachments are for the removal of unnecessary culverts, recontouring of the channel, and armoring and/or mulching as necessary to minimize erosion. One (1) encroachment is to remove an on-channel livestock pond and replace with an off-channel water trough. Work for this encroachment will include excavating the berm and culvert at the pond outfall, re-establishing the natural channel and stabilizing the area with rock and/or mulch as necessary to minimize erosion. The new trough will be located downstream from the existing pond at least 50 feet from watercourses and work will include grading to accommodate the new 6-foot water trough and the installation of an automatic shutoff valve and wildlife escapement ramp.
