PROPOSED IMPROVEMENTS

Improvements generally consist of replacing existing water and sewer mains, water and sewer services, fire hydrants, streetlights, asphalt structural section, and defective select edge improvements such as curb and gutter that impedes stormwater flow and sidewalk that contains tripping hazards for essentially entire project limits previously identified.

Design of the Project will include evaluating the existing right-of-way to accommodate widening or narrowing the existing roadway sections to a typical City standard roadway section on Beal Rd., Navajo Rd., and Navajo Dr. Design will also include evaluating the addition of sidewalk and parkway on one or both sides of the roadway where sidewalk does not currently exist on Beal Rd., Navajo Rd., and Navajo Dr. south of Beal Rd. The inclusion of these potential roadway improvements to the Project will be determined by the outcome of the investigations by the selected Engineering Professional and feedback received at the three Design Phase Public Outreach Meetings.

COMMUNITY BENEFITS

• Replacing and or abandoning aged and undersized existing water and sewer infrastructure, ranging from 35 – 72 years old, to meet current standards.

• Replacing aging and deteriorated asphalt that is no longer maintainable with a chip seal or overlay and improving the streets ride quality and longevity.

• On Beal Rd., Navajo Rd., and Navajo Dr. south of Beal Rd., evaluating existing right-of-way and roadways sections to include new sidewalk improvements that don’t currently exist, providing a safe place for pedestrian travel.

• Analyzing drainage issues to be improved to extend the life expectancy of the pavement.

• Reducing required maintenance with the construction of the new infrastructure.

• Coordinating construction on multiple streets to minimize inconveniences to the public and to reduce costs.

• Replacing defective select edge improvements such as existing curb and gutter that impedes stormwater flow and existing sidewalk with tripping hazards.

FUNDING SOURCE

The Coconino Estates Improvements Phase I Project is mainly funded by the Road Repair and Street Safety Program (RR&SS) approved by Flagstaff voters on November 18, 2014, a.k.a. Proposition 406.

The RR&SS – Utility Replacements and Overlays funding is generally limited to only improving existing infrastructure on streets that qualified to receive roadway and utility improvements based on their existing pavement overall condition index (scale of 100-0) being at or below 50 and their existing utilities needing repair or replacement due to consistent maintenance or age.

Since the RR&SS funding is generally limited to only improving existing infrastructure an alternative funding source may need to be identified during the Design if improvements that do not currently exist are to be added to the Project. The alternative funding source for including sidewalk where it does not currently exist will most likely be the Transportation Tax, Proposition 419.

CONSTRUCTION INFORMATION

Construction is anticipated to start spring 2020. 

Construction is anticipated to end fall 2021.

What you can expect for Construction:

• A public meeting will be held prior to construction to inform the neighborhood about the construction sequencing and schedule.

• Work will continue through the winter if weather allows.

• Soft closures are anticipated for the duration of the Project, with residential access only.

• Hard closures will occur occasionally at various locations where they will be no access.

• Working hours are anticipated to be from 7:00 am to 5:00 pm Monday through Thursday, subject to change pending weather conditions, progress, and agreed upon hours with Eagle Mountain Construction.

• Contractor available 24/7, Emergency Contact information distributed prior to construction.

Accessibility

• The contractor is responsible for maintaining driveway access to the best extent possible.

• Maintaining vehicle access to homes will be a priority

• Emergency access will be ongoing.

• Mail delivery will be continued as is.

• Trash & recycling will be on its normal schedule.

Generic Construction Phasing

• Utility work for Water, Sewer, and Storm Drain will be first.

• Water and sewer service will be disrupted to connect new service lines. The contractor is expected to notify and minimize disruptions to the best extent possible.

• Franchise utilities work independently but concurrently will be coordinated to minimize disruptions.

• Concrete sidewalk, curb & gutter, driveways, and valley gutter work will follow the utility work.

• Pavement work will follow the completion of the utility and concrete work.

• Removal of existing asphalt pavement

• Subgrade preparation - remedial action for unsuitable materials and grading

• Installation of aggregate base material

• Asphalt paving

TRAFFIC STUDIES

W. Navajo Rd. – N. Navajo Dr. to N. Fort Valley Rd.

The Transportation Program set traffic tubes just east of Hopi Drive on Navajo Road the week of November 11th, 2018. The speed counts illustrated that the 85th percentile speed is 28 mph and the average (mean) speed is 24 mph. The 85th percentile is the speed at, or below, which 85 percent of vehicles travel. Therefore, with a weekday average daily traffic of 1,072 vehicles, approximately 911 vehicles are traveling 28 mph or lower. Since the speed limit on Navajo Road is 25 mph and the 85th percentile speed is 28 mph, the City does not believe there is a speed concern. If the 85th percentile speed was greater than 30 mph, on a street with a posted speed limit of 25 mph, the City may research methods of reducing speeds.

W. Beal Rd. – N. Navajo Dr. to N. Fort Valley Rd.

The Transportation Program set traffic tubes just east of McMillian Road on Beal Road the week of November 11th, 2018. The speed counts illustrated that the 85th percentile speed is 28 mph and the average (mean) speed is 24 mph. The 85th percentile is the speed at, or below, which 85 percent of vehicles travel. Therefore, with a weekday average daily traffic of 1,452 vehicles, approximately 1,234 vehicles are traveling 28 mph or lower. Since the speed limit on Beal Road is 25 mph and the 85th percentile speed is 28 mph, the City does not believe there is a speed concern. If the 85th percentile speed was greater than 30 mph, on a street with a posted speed limit of 25 mph, the City may research methods of reducing speeds.

N. Navajo Dr. – W. Beal Rd. to W. Whipple Rd.

The Transportation Program set traffic tubes just north of Whipple Road on Navajo Drive the week of September 9th, 2019. The speed counts illustrated that the 85th percentile speed is 23 mph and the average (mean) speed is 19 mph. The 85th percentile is the speed at, or below, which 85 percent of vehicles travel. Therefore, with a weekday average daily traffic of 221 vehicles, approximately 187 vehicles are traveling 23 mph or lower. Since the speed limit on Beal Road is 25 mph and the 85th percentile speed is 23 mph. If the 85th percentile speed was greater than 30 mph, on a street with a posted speed limit of 25 mph, the City may research methods of reducing speeds.

N. Navajo Dr. – W. Navajo Rd. to W. Beal Rd.

The Transportation Program set traffic tubes just south of Havasupai Road on Navajo Drive the week of September 9th, 2019. The speed counts illustrated that the 85th percentile speed is 25 mph and the average (mean) speed is 21 mph. The 85th percentile is the speed at, or below, which 85 percent of vehicles travel. Therefore, with a weekday average daily traffic of 414 vehicles, approximately 352 vehicles are traveling 21 mph or lower. Since the speed limit on Beal Road is 25 mph and the 85th percentile speed is 21 mph, the City does not believe there is a speed concern. If the 85th percentile speed was greater than 30 mph, on a street with a posted speed limit of 25 mph, the City may research methods of reducing speeds.

SIDEWALK SURVEY AND RESULTS

Click here to see the sidewalk survey that was distributed.

A total of 548 sidewalk surveys were mailed directly to property owners in the area surrounding the Project. Click here to see a map of the survey extents.

Of the 548 sidewalk surveys that were mailed out 190 (35%) of the surveys were filled out and returned.

In order to maximize sidewalk survey responses, Beta PR Staff went door to door to properties along the Project to hand deliver the sidewalk survey and allow the property owners to ask questions, fill out, and return the survey in person. Beta PR made multiple door to door attempts to contact property owners if they could not be contacted on the first attempt.
