For studies that will have a significant impact, the National Environmental Policy Act (NEPA) requires an EIS document that provides an examination of environmental impacts for each of the proposed route alternatives. The team will evaluate hazardous materials, cultural and biological resources, socioeconomic and geological conditions, land ownership, air quality, noise impacts and water resources.
Alternatives Selection Report
The study team is collecting and analyzing technical information and input received from agencies, stakeholders and the public, which will lead to the development and review of possible route alternatives that will be documented in an Alternative Selection Report. The team is also looking at the impact of not making any improvements (also known as a no-build option). The focus is to avoid or minimize conflicts with man-made structures and natural resources. ADOT is working closely with representatives of government agencies in the study area.
Location/Design Concept Report (L/DCR)
Once the study team has narrowed down possible route alternatives, they will study them more in depth during the preparation of the L/DCR. The L/DCR will identify a preferred route alternative, define initial right-of-way needs and present an implementation plan. Project costs and preliminary design plans will also be included. The study team will present possible route alternatives to the public for review and comment at public meetings.
After public input, the team will then study the route alternatives more in depth in a Location/Design Concept Report (L/DCR) and an Environmental Impact Statement (EIS) as required by the National Environmental Policy Act (NEPA). The L/DCR will document a preferred alternative route, define initial right-of-way requirements and include an implementation plan. Project costs and preliminary design plans will also be included.
Once the draft EIS is approved, a public hearing will be held for final public review and comment. This is anticipated to take place in early 2013.
