Alternatives Selection Report (Dec. 4, 2017)

Alternatives Selection Report

The purpose of the Alternatives Selection Report is to document the development, evaluation, and screening of corridor options for the I-11 Corridor from Nogales to Wickenburg. Through this process, a reasonable range of alternatives was identified to be carried forward into the Tier 1EIS for further study. The Tier 1 EIS will assess a set of Build Corridor Alternatives (i.e. alternative corridors from Nogales to Wickenburg) and its component corridor options, along with the No Build Alternative (i.e., do-nothing option).

2017 Agency and Public Information Meeting Summary Report(Nov. 30, 2017)

2017 Agency and Public Information Meeting Summary Report

This Agency and Public Information Meeting Summary Report documents the outreach process that FHWA and ADOT completed for the I-11 Corridor Study at the end of the alternatives analysis phase. It summarizes the methods, meetings, and materials used to solicit feedback, as well as the comments and input received from the agencies, tribal governments, and public during the approximate 30-day comment period from April 28, 2017 to June 2, 2017. This report, in combination with the January 2017 Scoping Summary Report, documents the public input to the alternatives development and screening process.

Tier 1 Environmental Impact Statement Annotated Outline and Methodology(Oct. 13, 2017)

Tier 1 EIS Annotated Outline and Methodology

The purpose of the Tier 1 Environmental Impact Statement Annotated Outline and Methodology is to describe the content and organization of the Draft Tier 1 EIS so the researchers, section writers and reviewers understand what information and level of detail to include in the document. It provides a general outline of the content of the Tier 1 EIS, along with key information regarding the approach to the analysis for each resource area.

 Alternatives Selection Report (ASR) Evaluation Methodology and Criteria Report(May 23, 2017)

Evaluation Methodology and Criteria Report

The purpose of the Evaluation Methodology and Criteria Report is to outline the overall approach for developing and screening corridor alternatives for the I-11 Corridor during the Alternatives Selection Report (ASR) phase. During the ASR phase, FHWA and ADOT identify a comprehensive range of corridor alternatives that meet the Purpose and Need, and assess these alternatives through an evaluation process that uses public and agency input, as well as various topographical, environmental, and other planning information to help identify opportunities and constraints. Ultimately, the screening process will yield a reasonable range of Build Corridor Alternatives that will advance into the Draft Tier 1 Environmental Impact Statement (EIS) with a No Build Alternative (i.e., do-nothing option) for a programmatic-level environmental review.

Purpose and Need(Feb. 28, 2017)

Purpose and Need Memorandum

The Federal Highway Administration and the Arizona Department of Transportation have developed the Purpose and Need Memorandum to provide background information on the evolution and planning context of the Interstate 11 corridor. It also presents the overall purpose of the I-11 corridor and outlines the factors that contribute to the need for a transportation facility within the corridor study area. The Purpose and Need is a fundamental part of the National Environmental Policy Act process and provides the basis for identifying, evaluating and screening corridor alternatives. It will be a key component in selecting a preferred corridor alternative or the no-build alternative for I-11.

Scoping Summary Report (Jan. 25, 2017)

The Scoping Summary Report documents the scoping process completed by the Federal Highway Administration and the Arizona Department of Transportation for the Interstate 11 environmental study between Nogales and Wickenburg. The scoping process is in compliance with the National Environmental Policy Act. The report summarizes the methods, meetings and materials used to solicit feedback, as well as the comments and input received from the agencies, tribal governments and public during the 45-day scoping period from May 23, 2016 to July 8, 2016.
