Caltrans Route 101 Willits Bypass

On the Willits Route 101 Bypass project we took advantage of our development expertise to procure a new borrow site that was seven miles closer to the project and allowed us to accelerate the schedule and make up time that had been lost from earlier delays.   In order to get this new borrow site permitted we had to work closely with the County and various Federal and State agencies to get a permit approved  in less than one year to excavate nearly one million cubic yards of soil.

Caltrans Route 70 Widening Project

On the Route 70 Widening Project we took advantage of our extensive development experience and our relationships with State and Federal Regulatory Agencies to develop three borrow sites that provided 1.2 million cubic yards of import borrow material for construction of the new highway that was moved using heavy off-highway earth moving equipment rather than highway dump trucks.  This not only reduced the impact to the environment and the traveling public by eliminating 100,000 highway truck loads of dirt, it also provided adjacent landowners with commercial catfish ponds as well as new wetland habitat for local wildlife.
