EcoPlan recently completed a complex bridge reconstruction project for the Arizona Department of Transportation and the Federal Highway Administration. The fieldwork involved documentation of existing resources, including wetlands, threatened and endangered species, critical habitat for protected species, and cultural resources. EcoPlan completed an alternatives analysis and worked in conjunction with engineers to reduce the environmental impact footprint. We provided information to the U.S. Fish and Wildlife Service and the Arizona Game and Fish Department for the development of a fish and native amphibian exclusion protocol and relocation plan for inclusion in the Biological Opinion. During our research, petroglyphs (featured above) were identified within the project limits. EcoPlan worked closely with the project engineers to successfully limit potential intrusion on these sites.
