Options and Alternatives:

2.  Reject the First Amendment to the Design-Build Services Agreement and direct Staff to re-negotiate the terms and fee structure with Ames.
Background/History:
The Lone Tree Overpass has been a planned project for over a decade in the Flagstaff community. The Lone Tree Overpass Study, which evaluated conceptual design options for the bridge was completed in 2010. The goal of the Project is to provide better connectivity for the City's transportation network and provide a grade-separated crossing over the BNSF Railway corridor and the future Rio de Flag channel, which increases safety and convenience for multi-modal commuters. 

The Overpass also coordinates with the future planned improvements of the Lone Tree Corridor reconstruction which was studied in a report completed in 2006. The Lone Tree Corridor and Overpass serves to connect the southern area of town with the Route 66 corridor and provides an option that reduces congestion on other roadway corridors.  

A portion of the Lone Tree Corridor from Sawmill Road to Butler Avenue is included in this Overpass design. This section of the corridor was included at this time to provide a coordinated improvement north and south of the Butler Avenue Intersection.

In November 2018, the voters were asked to approve a ballot measure to fund the Overpass (Proposition 420) and a separate ballot measure to fund the Corridor Improvements (Proposition 419). Both propositions passed.

In the fall of 2020, Ames was selected by a six-member evaluation committee as the most qualified service provider for the Lone Tree Overpass Project ("Overpass" or "Project") pursuant to the evaluation and ranking process per A.R.S. sec. 34-603.

On February 2, 2021, Council awarded the first design phase services agreement with Ames. Over the past five (5) months, the team has worked to complete preliminary design, including: traffic volumes and modeling, the Traffic Impact Analysis Report for the future ADOT Route 66 intersection, Rio de Flag coordination with US Army Corps of Engineers, rail relocation with BNSF Railway, and general roadway, structures, right of way, and drainage design with City Staff. 
Key Considerations:
There are many important considerations to the full development of the Lone Tree Overpass Project that the Project team will be coordinating, including: 
  • Extensive property acquisition and relocation of existing businesses and residents.
  • Coordination with BNSF Railway for property and rail impacts.
  • Coordination with the US Army Corps of Engineers for the future Rio de Flag Flood Control alignment.
  • Economic Impact investigation and mitigation considerations.
  • Coordination with Arizona Department of Transportation and integration of a new intersection at the proposed Lone Tree and Route 66 juncture.
  • Adherence with our Climate Action and Adaptation Plan and Climate Emergency Plan.
  • Coordination with the Southside Community Specific Plan.
  • Coordination with the Active Transportation Master Plan for bike/ped connectivity and safety.
  • Public Involvement.
With the preliminary design work completed this year, the Project is now ready to progress to geotechnical investigation, potholing, survey, and property acquisition relocation support, which will be funded by this First Amendment to the Design-Build Services Agreement.
Expanded Financial Considerations:
The Lone Tree Overpass Project is currently budgeted in FY2021-2022 in the amount of $8,686,681 in the Transportation Fund, Account Number 047-05-112-3054-6. The Lone Tree Corridor Project is currently budgeted in FY2021-2022 in the amount of $250,000 in the Transportation Fund, Account Number 048-05-118-3495-6. Both funds will be utilized to complete the attached project scope from Route 66 to Sawmill Road.

In November 2018, the voters were asked to approve a ballot measure to fund the Overpass (Proposition 420) and a separate ballot measure to fund the Corridor Improvements (Proposition 419). Both propositions passed.
Community Benefits and Considerations:
The Lone Tree Overpass will provide a new roadway corridor and bridge over the BNSF Railway and the future Rio de Flag Flood Control Project, providing connectivity between Butler Avenue and Route 66 in central Flagstaff. Multi-modal transportation and alternative intersection design will be included in this Project to enhance all modes of transportation. This Project will also be designed with consideration of goals from the City's Climate Action and Adaptation Plan and the Southside Neighborhood Plan. An Economic Impact Analysis will also be developed to evaluate impacts for changes in transit behavior which will help identify future needs or mitigation.
Community Involvement:
There was extensive public coordination with the development of both the Overpass concept study and the Corridor Study in the early 2000's. There was also outreach performed for Proposition 419 and 420. The First Amendment with Ames includes public participation meetings, neighborhood outreach, development of a website to provide information, Project renderings to improve understanding of the proposed Project elements, and general public coordination throughout the design and construction of the Project. 
Expanded Options and Alternatives:
1.  Approve the First Amendment to the Design-Build Services Agreement to Ames as presented; or
2.  Reject the First Amendment to the Design-Build Services Agreement and direct Staff to re-negotiate the terms and fee structure with Ames.
