Work will generally include dewatering and removal of approximately 21,000 cubic yards of sediment from the creek bed of Novato Creek and its tributaries along the project reach. The sediment removal consists of 5,630 linear feet of Novato Creek from: Diablo Ave. to 500-feet downstream of the SMART Railroad Bridge, 1,780 linear feet of Warner Creek from Diablo Ave. to the confluence with Novato Creek, and 680 linear feet of Arroyo Avichi Creek from South Novato Blvd. to the confluence with Novato Creek. Channel bottom widths vary from 20-feet to 125-feet with approximately 3-feet of accumulated sediment. Work shall be performed by using equipment such as draglines, excavators, dozers, and dump trucks. Final grading work is required upstream of Redwood Blvd. for a relatively smooth channel bed with a low flow channel. All construction and sediment removal will occur in the creek bed during the low flow period of July 1 October 15th. Sediment removal downstream of the SMART Railroad Bridge shall not begin prior to September 1st. All excavated material may be temporarily stockpiled at approved locations within Heron's Beak Pond, along Duck Bill Pond Levee, and at Hanna Ranch Road Temporary Stockpile for future reuse for upcoming restoration projects. Any material stockpiled within the project site and all material deposited at the disposal sites shall be maintained by the Contractor using best management practices to ensure this material is not discharged into the surrounding wetlands.
