Approx. 6,560 CY of material will be excavated to construct or enhance 0.6 miles of new or enhanced flood plain side channels. Suitable soil material from side channel excavation is the designated borrow source for the proposed parking lot embankment and any roadway subgrade fill. It's estimated that 1,250 CY of subgrade fill material will be required for the parking lot embankment and roadway subgrade fill. Excavated side channel material that is not utilized on-site as fill (approx. 5,310 CY) shall be properly disposed of off-site by the Contractor.
