(Eagle Mountain), for the Spruce Wash Drainage Improvements Projects to add the Phase 2 - GMP 2 in the total amount of $7,614,149.06 and 180 calendar days to the contract duration.

Approval of this First Amendment will authorize the roadway improvements for Grandview Dr. (Phase 2); clearing of trees and initial grading work for utility relocations for Linda Vista-Cedar Channel (Phase 1); Linda Vista Crossing; and The Wedge Utilities (Phase 2). Staff intends to present any additional GMPs for remaining Projects for Council’s consideration at a later date. Please refer to the attached context and vicinity maps.
 
Construction of the Suite of Projects began in September of 2023 with GMP 1 for the underground utilities portion of the Grandview Project and Wedge Clearing. Pending Council’s approval of the First Amendment, construction of the Projects within GMP 2 will begin in March of 2024 and the originally approved 845-calendar day duration for the Construction Phase Services Agreement - Phase 1 and will be extended 180 calendar days for GMP 2 for a total of 1,025 calendar days. The extended duration is anticipated to cover construction of the entire Suite spanning over four construction seasons and targeting completion prior to monsoon season of 2026. Design is nearing completion on the remaining Projects within the Suite and is anticipated to be completed this spring 2024. The final scheduling and construction sequencing of the Suite will be determined once design is finalized.
 
The majority of the improvements in the Suite of Projects will be constructed within City property, in City right-of-way, and or within the existing public utility and drainage easement along Spruce Wash. Property acquisitions, additional public utility and drainage easement, and temporary construction easements are not required for the work included in GMP 2 but will be required for some of the Projects within the Suite, which will be finalized as design is completed.

The following projects and or portions of projects within GMP 2 will be funded by Proposition 441 Funds under the General Obligation Capital Project Funds from the following associated fiscal year budget appropriations, budget line items, and account numbers:

      2. Suspend or cancel the project completely.

On July 21, 2019, the Museum Fire broke out in the Dry Lake Hills area just above Flagstaff within the Coconino National Forest. The fire ultimately charred 1,961 acres, including a significant portion of the Spruce Wash Watershed. Flood modeling subsequently showed potential flood risk to neighborhoods in Coconino County and the City of Flagstaff. Throughout the summer of 2021, unprecedented rain events impacted the Museum burn scar and caused multiple rounds of flash flooding in Flagstaff neighborhoods.
 
In the November 2022 election, voters approved Proposition 441 with support from 76% of Flagstaff voters. The Proposition invests $57 million in City of Flagstaff wildfire suppression, stormwater flood mitigation and wastewater treatment infrastructure. Specifically, $26 million of this funding will be used to fund stormwater infrastructure improvements in the Spruce Wash area to lessen the impacts of flooding in affected neighborhoods. 
 
The development of the Spruce Wash Technical Feasibility Study Phase I and Phase II conducted by Peak Engineering identified eight Projects to be constructed with the $26 million in funding from Prop 441 to mitigate post-wildfire flooding in the Spruce Wash. The Suite of Projects will be constructed in addition to the Park Way Basins and the Killip Basins Inlet, which are funded through other sources.
 
On December 15, 2022, Purchasing staff solicited a Request for Statement of Qualifications for CMAR design and construction phase services. On January 13, 2023, Purchasing received Statements of Qualifications (SOQs) from the following five construction firms: Banicki Construction, Eagle Mountain Construction, Fann Contracting, Kinney Construction, and Tiffany Construction Company. A nine-member selection committee of City staff, three outside engineering consultants, and an outside contractor executive evaluated the SOQs. After the selection committee review process and negotiations, in early April 2023, the City’s qualifications based selection process identified Eagle Mountain Construction, Inc. as the most qualified Contractor to perform the CMAR design and construction phase services for the Suite of Projects.

The First Amendment adding Phase 2 - GMP 2 includes the roadway portion of the Grandview Project, the Linda Vista Crossing Project, the franchise utility portions of the Linda Vista to Cedar Channel Project, and the utilities portion of the Wedge Detention Basin Project. The remaining Projects within the Suite of Projects will be presented for Council’s consideration mid 2024 as additional GMPs. Please refer to the attached context and vicinity maps.

The Suite of Projects consist of the following eight Projects:

1. Grandview Drive Reconstruction – a reconstructed inverted crown street with a modified rolled curb instead of a typical rolled curb to increase stormwater capacity of the roadway on Grandview from Linda Vista to Cedar including the side-streets, and replacing and lowering the existing aging water and sewer infrastructure to ensure proper cover with the lowered roadway.

2. The Wedge Detention Basin – a detention basin to receive diverted flows from Spruce Wash.

3. Linda Vista Drive Crossing – a new box culvert to increase the inlet and downstream channel capacity and reduce the potential for overtopping of Linda Vista Drive. 

4. Cedar Avenue to Linda Vista Drive Channel: a re-graded and hardened channel to improve capacity for stormwater runoff conveyance.   

5. Cedar Avenue Crossing: a new box culvert to increase the inlet and downstream channel capacity.
6. Arroyo Seco Drive to Dortha Avenue Channel: a re-graded and hardened channel to improve capacity for stormwater runoff conveyance.
7. Arroyo Seco Drive Inlet: a reconstructed inlet structure for the purpose of increasing the inlet capacity to capture more stormwater into the downstream existing 60-inch storm drain.
8. Killip Basins Outlet: a new outlet structure from the Killip Regional Detention Basins to an existing storm drain in Main Street to serve as a secondary outlet for larger storm events, preventing water from overtopping the basins.  

Design is nearing completion on the remaining Projects within the Suite and is anticipated to be completed this spring 2024. The final scheduling and construction sequencing of the Suite of Projects will be determined once design is finalized.
 
The majority of the improvements in the Suite of Projects will be constructed within City property, in City right-of-way, and or within the existing public utility and drainage easement along Spruce Wash. Property acquisitions, additional public utility and drainage easement, and temporary construction easements are not required for the work included in GMP 2, but will be required for some of the Projects within the Suite, which will be finalized as design is completed.
 
The CMAR method of procurement was selected to expedite the design and construction schedule and to accommodate the complex sequencing of construction activities for this large-scale complex Suite of Projects with limits in an established neighborhood, near multiple schools, on high traffic volume streets with Mountain Line bus routes, and in a wash that experiences post-wildfire flooding. The CMAR process is a collaborative effort, which allows for flexibility with delivering the design and construction of the Project, as well as an open dialog between the City, the Design Consultant, and the Contractor on critical design and construction issues to minimize impacts to the community during construction.

The Spruce Wash Flood Mitigation Suite of Projects is funded by the November 2022 voter approved Proposition 441 Wildfire, Flood, and Wastewater Infrastructure Bond, which dedicated $26 million towards flood mitigation projects.
