Flood Control Bypass
The city of Napa, California, has secured the funding for a quarter-mile flood control bypass, along with more vegetation, to help with erosion control. It will provide an escape valve for Napa River floodwaters. However, most of the time, the bypass will be dry and open for the public to walk on.
The restored landscaping will provide better erosion control, according to the Napa County deputy public works director. Plans call for native grasses and bunch grasses in the center bypass section, with roots extending through a mat.
