RIDOT - Environmental Division - Natural Resources Unit

Natural Resources Unit

The RIDOT NRU provides environmental expertise and regulatory process guidance to RIDOT staff, consultants and contractors, and are liaisons to state and federal agencies, and other governmental, and non-government organizations to accomplish the transportation mission and meet environmental responsibilities.  

National Environmental Policy Act (NEPA)

The national commitment to the environment was formalized through the passage of the National Environmental Policy Act (NEPA) of 1969. NEPA establishes a national environmental policy and provides a framework for environmental planning and decision making by Federal agencies. NEPA directs Federal agencies, when planning projects or issuing permits, to conduct environmental reviews to consider the potential impacts on the environment by their proposed actions.

The Council on Environmental Quality (CEQ) regulations (40 CFR §§ 1500-1508) address the basic decision-making framework and action forcing provisions established in NEPA.

Environmental Permitting

The RIDOT Natural Resources Unit assists in determining permitting requirements for projects and oversees and reviews consultant prepared applications for content and accuracy. NRU acts as the main liaison with federal and state regulatory agencies such as the U.S. Army Corps of Engineers (USACE), the United States Coast Guard (USCG), the RI Department of Environmental Management (RIDEM), and the RI Coastal Resources Management Council (CRMC).

RIDOT Road-Stream Crossing Design Manual

RIDOT requires road-stream crossings that will be replaced to follow the RIDOT Road-Stream Crossing Design Manual. The design standards presented in this Manual apply to all RIDOT owned road-stream crossings.
