Environmental Management

Natural and human environmental issues have become key components of most infrastructure projects. Obtaining public input and understanding community needs benefit the environmental review process. In addition, a forum is provided to address community concerns, questions about design standards, project delivery and management issues. This forum facilitates consensus for the eventual decision and saves costs by incorporating social, economic, and environmental considerations early in the process when it is easier to accommodate change.
