Channel bottom widths vary from 20-feet to 125-feet with approximately 3-feet of accumulated sediment. Work shall be performed using draglines, excavators, dozers, and dump trucks. Final grading work is to be done with dozers and graders upstream of Redwood Blvd. All new construction and dredging will occur in the creek bed during the low flow period of July – October 15, 2016.
