The Hamilton City Project is a dual-purpose flood risk management and ecosystem restoration project. The project has constructed 6.8 miles of levee for improved flood protection and will restore approximately 1,400 acres of native habitat. The new setback levee will provide improved levels of flood risk management and levee stability. The restoration work will benefit the recovery and stability of numerous federal and state-listed species and provide a more natural river function, contributing significantly to aquatic ecosystem restoration along this reach of the Sacramento River.

The Hamilton City community has long been at risk of flooding from the Sacramento River. Extensive, repeat flood events have resulted in the evacuation of the community several times in the past.  The new levee system and restoration areas will provide additional flood protection for the community.
