Napa Creek box culverts reduce flood risk
A construction worker carries lumber through a set of box culverts under construction along Napa Creek in Napa, Calif., Jan. 18, 2012. The culverts – tunnels large enough for a car to drive through – will channel flood water from the creek more quickly to the Napa River and way from homes and businesses. The $14.8 million project, funded by the American Recovery and Reinvestment Act of 2009, was a joint effort of the U.S. Army Corps of Engineers Sacramento District, the city of Napa and the Napa Flood Control and Water Conservation District to reduce flood risk for the city.
