2020 Periodic Updates

(These updates provided by Coconino County cover the overall project, including the water and sewer upgrades)

November 20

Two crews are currently deployed constructing sewer line. Crew 1 is working between Purple Sage Rd. and Fort Tuthill County Park. Crew 2 completed a Mt. Dell Water Company water line relocation this week; and Crew 2 has prepped and is completing paving on Mt. Dell Rd.

The paving at the east section of Mt. Dell Rd./Palmer Ave. is being completed 11/20 and 11/23. Traffic control will be modified during paving operations including the use of signalized traffic control. This will be in place the weekend of 11/20.

The remaining pavement will be scheduled as soon as sewer work can be completed in the westerly road section in Mt. Dell.

Traffic control is in place on Palmer Ave. and on FS 532.

The Contractor has been directed to continue to place additional AB material on Mt. Dell Rd. as needed to keep the surface as smooth and drivable for the public as is reasonably possible until paving can be completed.

Gabion basket erosion control mats were installed this week.

FUTS temporary detours remain in place at the south end of project area along Purple Sage Rd. and in Fort Tuthill County Park. FUTS trail users are rerouted onto temporary singletrack between Mt. Dell and Purple Sage Rd. and users should follow signs.

The Contractor has adjusted the anticipated completion date to December.

November 13

Two crews are currently deployed to construct the sewer line; Crew 1 is working between Purple Sage Rd. and Fort Tuthill County Park, and Crew 2 is installing manholes at the Purple Sage Rd. crossing. Crew 2 is also working with Arizona Public Service (APS) to complete sewer installation in close proximity to an existing APS power pole at Purple Sage Rd.

 

A Mt. Dell Water Company water main was encountered in Palmer Ave. The line runs through the sewer alignment at a shallow angle for approximately 250LF and the line will need to be relocated. We have reached out to Mt. Dell Water Company to coordinate the relocation and work has been suspended in Palmer Ave. until the water line can be relocated.

 

The east section of Mt. Dell Rd./Palmer Ave. is proposed to be paved at the end of next week. Traffic control will be modified during paving operations including the use of signalized traffic control. Traffic will be restricted to one lane for Nov. 18-20 for preparation and paving. The remaining pavement will be scheduled as soon as work can be completed in the westerly road section in Mt. Dell.

November 6

Work has been progressing on the Fort Tuthill Utility Improvement Project, with this week’s work expanding on the work mentioned last week.

 

Two crews continue to work on the project. Crew 2 has been making good progress between Mt. Dell and Purple Sage Rd. and will cross Purple Sage Rd. next week, weather allowing. Crew 1 is working through Mt. Dell on Palmer Ave. Where the trench is deep, they are working around rock and clay/unsuitable material and the going is slow.

 

Pavement submittals have been received and the Contractor is proposing a two-phased paving operation in light of the slow going in Palmer Ave. First paving will occur at the eastern end of Mt. Dell Rd. while Crew 1 continues to install sewer main on Palmer Ave. The 2nd phase of paving is proposed to happen a week or two later once Crew 1 completes work on Palmer and moves to the west out of the paved road and into an unpaved road section.

 

October 30

For the sewer line work, two crews are currently deployed, with Crew 1 working in the Mt. Dell community and installing 18" sewer main and 4" private sewer service connections, and Crew 2 working south of the community in the FUTS trail and installing 18" sewer main.

Traffic control is in place with single lane closures and flaggers at each end of the construction zone.

Gabion baskets scour protection is being installed at the north section of the project and will continue through next week.

Rock and unsuitable material are slowing progress in Mt. Dell. The project will conduct complete pavement restoration for all disturbed areas necessitated by the construction of the new sewer main and sewer service lateral connections within Mt. Dell roads. The pavement will be replaced per City of Flagstaff standards for pavement replacement in existing paved streets (City of Flagstaff Standard Detail 9-01-030). This pavement work is projected to happen at the end of November and is anticipated to take about two days to complete. The contractor has been directed to place additional AB material on Mt. Dell Rd. as needed to keep the surface as smooth and drivable for the public as reasonably as possible.

FUTS temporary reroutes at the south end (from Purple Sage Road into Fort Tuthill County Park) remain in place and trail users are temporarily rerouted onto Purple Sage Road. Please watch for vehicular traffic and follow detour signs.

FUTS Trail users are also rerouted onto temporary singletrack between Mt. Dell and Purple Sage Rd. and should follow signs.

Parks and Recreation staff placed trail closed signs at the north and south end of the social trail at the northerly portion of construction in University Heights. Though not a sanctioned trail, it is well used and crosses the construction zone.

The contractor is anticipating project completion in early December.

October 23

The work from last week continues; you can read the full 10/16 update on our website. Additionally, a closeout plan for the social trail at the north end of the project was reviewed and endorsed by the landowner, and the restoration work on the social trail will begin soon. Attached are a couple of additional photos from last week.

October 16

The water line work is 100% complete

For the sewer line work, a second crew is mobilized to complete work south of Mt. Dell. This crew will be working from Mt. Dell to Fort Tuthill concurrent with the crew working in the Mt. Dell community. 

Construction is proceeding with down the Mt. Dell Road right away where 18" diameter pipe and manholes are being installed. 

Traffic control is in place with single lane closures and flaggers at each end of the construction zone.

Installation of the 4" private sewer service connection is underway. The Contractor is completing outreach to private parcel owners as work proceeds. 

Gabion baskets scour protection will be installed at the north section of the project area beginning next week. 

Six (6) additional tree removals were required along the trail between Mt. Dell and Purple Sage.
