Green Valley Creek is located in the City of Fairfield in southern Solano County. The Creek, which was home to a dwindling number of salmon, was being choked by heavy sediment runoff from neighboring tributaries. The increased sediment loads also raised the creek bed, causing increased local flooding. Working with the City and a hydrologist from MacKay and Somps, we designed an overflow terrace to carry flood flows through existing and restored riparian woodlands and native grasslands. Permitting included a Corps individual permit, consultations with USFWS and NOAA fisheries, the RWQCB and the CDFG. Construction was completed just in time to meet some of the worst storms in California in three decades. However, the creek performed as designed and anadromous fish runs have increased, while flood protection has been assured for adjacent homes.
