Description of the Evaluation Matrix / Corridors Being Evaluated

SR 802: Williams Gateway Corridor Study / SR 202L to Florence Junction Evaluation of Alignment Alternatives 05/05/2009

Description of the Evaluation Matrix / Corridors being evaluated:

During the public meetings held in December 2008, several alignment concepts were developed and presented for consideration; A1, A2, B, C, and D. These alignments were all developed generally within the confines of Corridors 2 and 4 during the initial Tier 1 evaluation of this study, and which had received the greatest support from both the public and agency representatives. Since the public presentation, two other alignment concepts were submitted to the Study Team for consideration: Alignment B was divided into two concepts with B1 travailing parallel to and west of the CAP canal between Germann and Ocotillo Roads, and B2 traveling east of the CAP, and Alignment E was added as the most northern alignment concept through State Lands. Both of these new concepts, along with the other presented corridors, are shown on the attached Tier 2 Alignment Exhibit.

Tier 2 Evaluation Criteria and Agency Input in the Alternatives Evaluation:

The following table provides the Tier 2 Evaluation Criteria. The Study Team will complete a detailed evaluation of each alignment based on the criteria. For each criteria, the study team would like your evaluation of the various alignments, providing any insights you have on each of the criteria provided. While the Study Team will make all quantitative evaluations based on the actual footprint, length, location, and potential impacts, your input on qualitative evaluations is desired. It is important to note that this evaluation exercise is part of the comprehensive alignment evaluation process that includes bringing the public input and the completion/determination of the “Purpose and Need” that ADOT and FHWA is working on completing. Your input is critical at this phase. Please share any insights, pro or con, on the alignments that can be used in the evaluation of the alignment options.

At the end of the evaluation, provide to the Study Team your overall rating of each alignment, along with any comments that led you to your rating. These will all be compiled and shared when the Study Team completes its evaluation and recommendation for continued study as part of the DCR and EA process.

Criteria Description Performance Measures Comments

Mobility Connectivity to Regional Freeways / Provides seamless connections with existing State Highways, and major routes or planned regional facilities (i.e. freeways, State highways and regional arterials), located to serve the larger, regional area for the short and long term needs

Separation of Regional Freeways / State Sufficient lateral separation between freeway Highways, and major routes facilities, and freeway-to-freeway system interchanges

Visual Quality Impacts to existing residences, planned Number of residential properties where distinct residences and/or other desirable background features (e.g. Superstition vantage points Mountains, San Tan Mountains, etc) from the proposed alignment alternatives are partially or otherwise obstructed General Plan Relationship of alignment alternative to Proximity to compatible existing land uses Consistency existing development such as commercial, industrial, or economic nodes and to non-compatible existing land uses (parks, schools, residential)

Relationship of alignment alternative to Proximity to adopted land uses such as adopted land uses where development commercial, industrial, or economic nodes and and growth are expected to non-compatible adopted land uses (parks, schools, residential)
