Hamilton City is along the west bank of the Sacramento River in Glenn County, California, about 85 miles north of the City of Sacramento. The community has long been at risk of flooding from the Sacramento River. Portions of Hamilton City and the surrounding area flooded in 1974. Extensive flood fighting has been necessary in 1983, 1986, 1995, 1997, and 1998 to avoid failure of the private 'J' levee. Residents of the town were evacuated six times in the past 20 years: 1983, 1986, twice in 1995, 1997, and 1998. The community of Hamilton City relies on the existing 'J' levee to contain flows in the Sacramento River. The 'J' levee does not meet Corps or any other levee construction standards and could fail at river levels well below the top of the levee.
The U.S. Army Corps of Engineers and The Reclamation Board of the State of California completed a feasibility study in 2004 to develop plans to reduce flood damages and restore the ecosystem along the Sacramento River near Hamilton City. The Hamilton City Flood Damage Reduction and Ecosystem Restoration Project will provide enhanced flood protection for Hamilton City through:
