Document Description
A Special Permit to allow various stream restoration & sediment control projects within the Mattole River watershed. The project area spans multiple parcels. Work will be conducted by the Mattole Restoration Council in cooperation with the DFG, Regional Water Board, DWR, Natural Resource Conservation Service, and a number of private landowners. The majority of the project activities fall within two categories: "Road related treatments (to Cartwright Road and Schmidt/Etter Ranch Road)" and "Instream treatments (along the Toews, Etter, Schmidt, and Scarpulla lands)". The following road surface treatments are proposed along three miles of road: rolling dips, berm removal, crowning, and out-sloping to reduce runoff concentration on the road surface. "Shotgun" or failed culverts will be replaced at approximately 20 sites with riprap rock armoring being placed around the outlet of an additional 10 culverts. Armored fords will be installed at 10 sites to upgrade fill-based crossings on class II streams. One double span flatcar bridge (approximately 175 feet long) is proposed to be installed across a portion of the Upper North Fork of the Mattole River. "Instream" treatments include: construction of willow baffles in association with bioengineered rip rap to provide streambank erosion protection, placement of bioengineered rip rap rock with a toe trench, and installation of large woody debris to improve fish habitat.
