Upper Berryessa Creek

Flood Control Project

Upper Berryessa Creek Flood Channel

Suulutaaq was the prime contractor for the Upper Berryessa Creek Channel Improvements project in Milpitas, CA involving the US Army Corps of Engineers (USACE) – San Francisco District and the Santa Clara Valley Water District.  The project consisted of all channel improvements, including widening/reshaping of the Berryessa Creek, placing riprap and erosion control blankets, improving channel crossings at five roadway and two railway bridges.

Upper Guadalupe River Relocation

Suulutaaq, as the primary subcontractor, completed construction of the Guadalupe River Channel Realignment Project in San Jose, California during November of 2012. This project realigned approximately 1,700 lf of the Upper Guadalupe River to create a larger flood plain. 16,000 CY of the existing channel were excavated. 10,500 CY were hauled to an onsite stockpile, while the remaining 5,500 CY were re-embanked to shape the new channel. An additional 700 tons of excavation was performed in the bottom of the channel to allow for the placement of 16 root wad structures.

The project required the diversion of all river flow through the project area during construction using a primary and secondary pumping system. Care was taken to avoid any damage or impact to fish, the river and the environment. The project also included the restoration and creation of aquatic habitat.
