Odin constructed approximately 2,690′ long seepage berm along the west bank of the Sacramento River. The seepage berm consisted of approximately 10,000 CY of sand, 7,000 CY of drain rock, and 10,000 CY of levee fill. The seepage berm consisted of layers with 12″ of sand to start, then 12″ of drain rock, then 6″ of sand, then levee fill with a minimum of 6″, with it all topped off with 6″ of topsoil. Rip rap was placed at the toe of the berm. An aggregate base road was built up next to the seepage berm at the same elevation as the first drain rock layer to allow water to flow out to the farm avoiding water containment along the berm and levee.

Also, the project consisted of clearing and grubbing 20,000 SY of vegetation and removal of a 24” pipe. MOJV built the subgrade, and constructed the seepage berm on a good foundation. All materials met the specification standards prior to placement. MOJV placed each layer of material with caution and the intent to not cross-contaminate. The MOJV team, AECOM, and USACE worked together as a team to achieve the project goals.
