Danley Road at Glenn-Colusa Main Canal Bridge

Colusa County, California

Foothill Associates provided biological resources services in support of the demolition of the antiquated Glenn-Colusa Canal Bridge structure and construction of a new bridge meeting modern public safety standards. Biologists wrote a Biological Assessment pursuant to Section 7 of the Federal Endangered Species Act in support of Caltrans consultation for giant garter snake with the U.S. Fish and Wildlife Service. The biological assessment describes the potential effects to the federally listed giant garter snake and its habitat, taking into consideration project-related impacts and conservation measures.
