Bridges & Biology Workshop

February 21-22, 2018, Sacramento, CA

​

This workshop was a partnership between Caltrans Structures Engineering and the Division of Environmental Analysis Office of Biological Studies, California Department of Fish and Wildlife, and NOAA’s National Marine Fisheries Service. The workshop provided a shared understanding of process and requirements of bridge planning, foundations investigation, and structures design, as well as biological and habitat resources coordination, investigations, impact analysis, permitting and implementation of avoidance, minimization measures and post-project monitoring.
