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.
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.
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.
The Public Outreach and Agency Coordination Plan identifies the outreach efforts that the Federal Highway Administration and the Arizona Department of Transportation will undertake during the environmental review process for the Interstate 11 Corridor Tier 1 Environmental Impact Statement. A key focus of the plan is to facilitate an understanding with the public, tribal governments and governmental agencies regarding the study process, key milestones and decision points.
The publication of the Notice of Intent in Federal Register represents the official start of the National Environmental Policy Act process. The NOI was published for the Interstate 11 Tier 1 Environmental Impact Statement on May 20, 2016.
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.
