Study Updates and Mailing List

Short study updates are frequently posted to the blog on the Good to Know page to inform the public and stakeholders when new information is available and to provide additional information on study-specific elements. Those on the study mailing list will receive an email each time a new update is posted. Join the Interstate - (I-11) Tier 1 Environmental Impact Statement (EIS) Mailing List to receive email blasts.

Scoping and Alternative Selection

To initiate the study in 2016, public and agency scoping meetings were held to understand the scope of issues to be addressed during the study. In 2017, the alternatives development phase of the study incorporated this scoping input to develop a wide range of alternatives, with the goal of narrowing them to a reasonable range of alternatives to be studied further throughout the phases of the study. These alternatives represent both public and agency input and meet the corridor’s Purpose and Need. The reasonable range of alternatives evaluated in the Tier 1 EIS includes the No Build Alternative.

Draft Tier 1 EIS

The EIS analysis phase is a detailed analysis of potential social, economic and natural environmental impacts of the proposed corridor options. The Draft Tier 1 EIS documented this analysis process, and identified a Recommended Alternative and was presented to the public for review and comment from April 5, 2019 through July 8, 2019. The range of alternatives evaluated in the Draft Tier 1 EIS included the No Build Alternative.

Final Tier 1 EIS

The study team considered all comments received on the Draft Tier 1 EIS, conducted additional analysis, and coordinated with stakeholders to prepare the Final Tier 1 EIS, which identified a Preferred Corridor Alternative for I-11. The Final Tier 1 EIS was completed and made available for public review (Final Tier 1 EIS document ) July 16 through August 16, 2021. The range of alternatives considered in the Final Tier 1 EIS included the No Build Alternative.

All public comments and questions received during the Draft Tier 1 EIS comment period were addressed in the Final Tier 1 EIS and can be viewed in Appendix H5.

Record of Decision

After public review of the Final Tier 1 EIS, FHWA and ADOT will issue a Record of Decision (ROD) that will present a Selected Corridor Alternative, which may be a Build Corridor Alternative or the No Build Alternative. The ROD will be published no sooner than 30 days after the publication of the Final Tier 1 EIS.

If FHWA and ADOT select a Build Corridor Alternative in the ROD, the build alternative would be implemented in smaller segments as funding is available. At this time, no funding has been identified to plan, design or construct any part of I-11, including any Tier 2 analysis.

If the No Build Alternative is selected, no project would occur.
