Public Information Meeting

US 93 – Wickenburg to Santa Maria River

Location/Design Concept Study

Dec. 5, 2001

 

The purpose of tonight's meeting is to present information and receive public comments on:

·       The US 93 bypass around Wickenburg.

·       The preferred Interim Improvements Project Alternative.

 

Welcome! The Arizona Department of Transportation (ADOT), in cooperation with the Federal Highway Administration (FHWA) and the Bureau of Land Management (BLM), is conduct­ing a Corridor Improvement Study of US 93 between State Route 74 and the Santa Maria River (Figure 1). The study will deter­mine the op­timum location and design con­cept for a proposed bypass around Wick­enburg and the widening of 35 miles of US 93 north of town. In addition, a separate Interim Improvement Design Concept Study is under­way to investigate alter­natives to alleviate traffic conges­tion in downtown Wicken­burg until the ultimate bypass is completed.

This is the third in a series of public informa­tion meetings designed to update the public on the progress of the studies and to gather your input. Tonight’s meet­ing will fo­cus on the status of the pro­posed US 93 by­pass around the Wicken­burg area and the pro­posed interim im­provement pro­ject within the town of Wick­enburg.

Need for the Project

 

US 93 is the primary high­way route linking the met­ro­politan Phoenix area to north­west Ari­zona and be­yond. It is also part of the National Highway System and has been designated as a North American Free Trade Agreement route. ADOT’s long-range plan is ultimately to provide a four-lane high­way from Phoenix to the Nevada state line. Improvements to the route are being made as traffic conditions war­rant and as fund­ing becomes avail­able.

The portion of US 93 between Wickenburg and the Santa Maria River is currently operating near capacity and it is expected that traffic volumes will increase markedly over the next 20 years. Given these conditions, together with the congestion on US 93 within Wickenburg, ADOT has determined that there is an immediate need to initi­ate route improvements.

 

Bypass Study

 

At the last public information meeting, held on August 22, 2000, ADOT presented the find­ings of the initial analysis of several Wickenburg bypass align­ments sug­gested by the public and ADOT. The Southwest and Far West bypass cor­ridors were presented as the most ap­pro­priate for a by­pass (Figure 2), with the Far West being the pre­ferred option. It was also stated that additional develop­ment and evaluation of specific highway align­ments within each corri­dor is needed.

Subsequent to the public meeting, the BLM found that the Far West Corridor would pass through a protected area that surrounds the cliff areas of Vulture Peak and Caballeros Peaks. The area was established by BLM’s Lower Gila North Management Frame­work Plan (MFP), which was approved in March 1983, to protect the nesting habitat of the prai­rie fal­con, golden eagle, barn owl, and great horned owl. This area, labeled on Figure 2 as a Raptor Protec­tion Area (RPA), is designated as a “signifi­cant special habitat feature” in the MFP.

Without a change to the BLM’s plan, the Far West alternative cannot be considered a feasible alternative. If ADOT were to proceed with the cor­ridor selection process at this time, the Far West Corridor would have to be dropped from further consideration, result­ing in the selection of the Southwest Corridor by default. However, the Study Team feels that the Far West Corridor should be fully analyzed, due to the public support for that route and the advan­tages that the Far West offers in compari­son to the Southwest Corridor. Another consideration is that the ultimate location of the proposed CANAMEX Corridor, which has not yet been resolved, could influence the align­ment and selec­tion of the bypass route.

In or­der to consider ADOT’s request for a transporta­tion cor­ridor across the RPA, the BLM would need to initiate a proposal to amend the current MFP. The amendment process involves full public participation and an environmental analy­sis. The analysis would determine whether the existing RPA designation is appropriate and whether it should be modified to allow the proposed trans­portation corridor. It is important to note that carrying out the BLM’s amendment process would not ensure approval of the Far West bypass corri­dor. In order to change the MFP, the BLM must demonstrate that the RPA designation is no longer valid or that the change in the plan is war­ranted by the need for the bypass to be located within the protected area.

Before the BLM will agree to begin the amendment process, the agency must have a com­pelling reason to justify the change to its current land use management plan. Therefore, ADOT has agreed to prepare a detailed Feasibility Report re­garding the vari­ous bypass routes, including a new Southern Loop (Figure 2), as a basis for the BLM to consider revisiting the RPA designa­tion status.

Regardless of whether or not the BLM amends the MFP to allow road construction through the RPA, continued consideration of a bypass route will take several years to complete. With the CANAMEX Corridor Study lagging well behind the bypass study, and with the uncertainty regarding a transportation corridor through the RPA, not enough information is available at this time to clearly define the ultimate bypass route. ADOT is committed to developing the Wicken­burg bypass; however, a final decision on the route selection will now be several years in the future.

In the meantime, ADOT will continue the de­velopment of a separate Location/Design Concept Report and an Environmental Assessment (EA) for US 93 north of Wicken­burg to the Santa Maria River, so that improvements to that segment of the highway are not delayed by the bypass study. A public informa­tion meeting will be held early next year to present details on this portion of the US 93 corridor improvement study.

Interim Improvement Study

 

At the last public information meeting, numer­ous alternatives were described and illus­trated as candi­dates for an interim im­prove­ment project to re­lieve existing con­gestion in Wick­enburg prior to con­struc­tion of the US 93 by­pass. Of the align­ments consid­ered, Al­terna­tives 7 and 13 were presented as the two op­tions with the most potential. Alternative 10, which would re­move parking from Tegner Street and Wick­en­burg Way to pro­vide room for two left-turn lanes, was described as the simplest and least costly solu­tion. Input from the public indicated vir­tually no sup­port for Alterna­tive 10, little sup­port for Alterna­tive 7, and a fair amount of support for Alternative 13. There were also many who op­posed all of the interim im­provement alter­natives. This input indi­cated that additional work was necessary to arrive at an al­ternative that could be recom­mended.

Since the last meeting, three additional alter­natives, numbers 14, 15, and 16, have been investi­gated. Illustrations of these alterna­tives, as well as Alternatives 7 and 13, are attached at the back of this handout. All alter­natives were evalu­ated based on 27 factors with the result that Alterna­tive 16 is being presented this evening as the preferred alternative. The primary reasons for prefer­ring Alternative 16 are:

·        Its terminus north of the APS substation would remove regional traffic farther from downtown Wickenburg than the other alter­na­tives, thereby having the greatest beneficial ef­fect upon local air quality, safety, and traf­fic operations.

·        It would be located farther away from residential communities between Coffinger Park and the Super 8 Motel, reducing po­ten­tial noise impacts on these neighborhoods. In addition, Alter­native 16 would minimize po­tential impacts on community cohesion, neighbor­hood character, and visual quality of the area by avoiding di­rect intru­sions into these residential areas.

·        It would avoid separating the existing commercial development on Tegner Street at the northern town limit from existing and potential commercial devel­opment immediately to the south. As a result, it would maintain the continuity of the commercial district and accommodate future de­velop­ment.

Comment Sheet

 

How Can You Participate?

 

Your input this evening is very impor­tant to the outcome of the study. Before and after tonight’s presentation, Study Team rep­resen­ta­tives will be available for you to dis­cuss the study project and ask ques­tions. Following the presen­tation, the meeting will be opened for comments and questions from the audi­ence. A court re­porter will be on duty to en­sure that the open session is recorded accu­rately for our use as we continue with the study.

Your input should be noted on the at­tached Com­ment Sheet. Please hand it to a Study Team representative tonight or send it to Bert Bertleson by December 19, 2001.

 

 

What Happens Next?

 

Following tonight’s meet­ing, the Study Team will review the input received from the public. The information will be used in com­pleting the design concept for the interim im­provement project. An Initial Design Concept Report and a Draft EA will be prepared and made available to the public early next year, followed by a public hear­ing where we will present our final rec­om­menda­tions. As men­tioned earlier, the design con­cept for improv­ing US 93 north of Wick­enburg is con­tinuing, with a public informa­tion meeting also planned for early next year.

No final decision or endorsement of any of the study alternatives has been made at this time by ADOT, the FHWA, or the BLM. An official decision will not be made regarding either the bypass or the interim improvement until: (1) the al­ternatives evaluation process has been docu­mented in an EA; (2) a public hearing has been held to present recommendations; and (3) the agencies and the public have had an opportunity to comment. These steps are required for compliance with the National Environmental Policy Act.
