Description of Work
The project is located at a tidal double 72"X72" box culvert which passes under Milton Road near the 1300 block of addresses. The culvert connects a drainage ditch to the Napa River. The culvert is fitted with a set of flapgates on the Napa River side and a trash rack on the ditch side. This project consists of removing and replacing the two flapgates. The new flapgates will be provided by Napa County. The culvert barrels will have to be plugged during replacement to prevent flooding of private land during construction.
The Contractor shall possess a Class A license at the time of contract award. The Engineer's estimate is $125,160.
