Napa Creek improvements extend for about one mile, from the Creek mouth at the Napa River upstream to Jefferson Street. The geomorphic design reduces flood water levels through the use of riverbank terracing and removal of old levees to reconnect the River to its historic flood plain. Other key features of the unique design include removing or replacing bridges that impede flood flows, and creating bypass channels at River and Creek oxbows.
