Elevate invert of channel to reconnet with historic floodplain to the extent feasible. Re -meander channel with appropriate dimensions, restore riparian wetlands adjacent to the channel, and install in -stream log cross canes, toe -wood and other woody debris to help maintain pools/restored profile. Establish a 75' wide riparian buffer along both banks of th restored channel. Reaches 2 - Restore headwater stream ::'-tJ{ system by filling the existing channel and establishing _ _ , - a 50' wide buffer to each side of the valley centerline. Existing trees and roots will be supplemented by tree, shrub and herbaceous plantings to provide a stabilized flow path for the restored system. Reach 1- Restore headwater stream system by filling the existing channel and establishing a 100' buffer to each side of the valley centerline. Existing trees and roots will provide stabilized flow path for restored stream and riparian wetlands.
