North-South Corridor Study: Potential New Transportation Route in Pinal County
The study is anticipated to be completed in 2017 and will include the following elements.
For studies that will have a significant impact, the National Environmental Policy Act (NEPA) requires an EIS document that examines environmental impacts for each of the proposed route alternatives and recommends the preferred alternative. The team will evaluate hazardous materials, cultural and biological resources, socioeconomic and geological conditions, land ownership, air quality, noise impacts and water resources.
Prior to the Draft EIS being approved, a public hearing will be held for public review and comment. This is anticipated to take place in 2016.
Alternatives Selection Report (completed)
The study’s alternatives selection phase was recently completed. It included the development and evaluation of a range of route alternatives, including the effects of taking no action on any improvements (also known as a no-build option).
The Alternatives Selection Report documents the process of developing and evaluating a range of reasonable alternatives. Impacts considered included existing and future developments, drainage, soil structure, utilities, travel demand, population growth and the long-range plans of each community along the route(s). In addition to the technical information and input from local, state and federal agencies and communities about their preferences, the team used the study Purpose and Need Statement as a guide to develop potential route alternatives.
The study team documented the alternative selection process in the Alternatives Selection Report. The Alternatives Selection Report, completed in October 2014, identifies the alternatives recommended for further study in the Draft EIS and Location/Design Concept Report (L/DCR).
Public information meetings were held in the fall of 2014 to provide information about the recently completed Alternatives Selection Report for the North-South Corridor Study. The study team documented the input received in the North-South Corridor Study Alternative Selection Report Public Meeting Summary.
Location/Design Concept Report
The study team has identified possible route alternatives, and they are currently being studied in depth with the preparation of the L/DCR. The L/DCR will develop a preliminary design concept for the 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 team is also studying the impact of not making any improvements (also known as a no-build option). All the alternatives identified and the no-build will be presented to the public for review and comment at public meetings.
The conceptual design will focus on avoiding or minimizing conflicts with human-made structures and natural resources. ADOT is working closely with representatives of government agencies participating in this study.
