DOT uses an environmental review process to inform strategies, resulting in better outcomes throughout our programs.
Transportation Planning
Sustainable transportation infrastructure begins with the planning process. Transportation decisions need to be made in an environmentally sensitive way, using a comprehensive planning process that includes the public and considers land use, development, safety, and security.
