000 Prior to commencing in-stream work, the construction site will be isolated from stream
" flow using flexible booms, and any fish in the construction zone will be removed. A
a a small tracked excavator will be used to handle sheeting and trench where necessary.
rrr Sheeting will be pushed in place as much as possible. Sheeting will be fastened to
lV N C4
concrete abutment using '/2" Parabolts(or equivalent system) to ensure safety during
construction. After repairs are completed, the site will be pumped of silty water.prior to
removing diversion booms. Disturbed vegetation will be reestablished with native
material where possible. Any soil exposed by construction will be straw mulched. An `
engineer will be on site during critical construction stages and approve final work. All
activities will be in accordance with an approved HPA.
