June 2012 34

Excavation to start at outlet structure (Sta 25+50) and extend upstream to Sta 225+00 Design reach length = 3.6 miles or 18,950’ Design reach length excludes CR 31 bridge reach which is 1,000’

Preliminary excavation quantity 5.2 million cubic yards 1.44 million cubic yards per mile of channel

Overall Project-Diversion Channel 35 miles of diversion channel Rough estimate of ~55 million cubic yards of channel excavation This estimate uses Design Reach 1 quantities to calculate rough estimate Volumes will change
