Accelerated Pavement Maintenance Program: Proposed Work Plans FY19-FY23
Description
This report provides information to the Aviation and Transportation Subcommittee on the acceleration of the proposed Transportation 2050 (T2050) five-year arterial and major collector streets pavement maintenance program. Staff requests the Aviation and Transportation Subcommittee recommend City Council approval of the proposed T2050-funded Five-Year Pavement Maintenance Program for FY19 - FY23.
THIS ITEM IS FOR DISCUSSION AND POSSIBLE ACTION.
Report
Summary
On Oct. 3, 2018, the City Council directed Street Transportation Department (Streets) staff to develop a plan to accelerate pavement maintenance on arterial and major collector streets over the next five years using $200 million to be funded through financing of Streets T2050 funding. In December 2018, the Council approved a plan for the acceleration of the previously planned five years (FY19 through FY23) of asphalt mill and overlay projects to be completed in less than two years (FY19 and FY20). This item brings forward the second phase of this acceleration, as Streets staff has repopulated the final three years (FY21 through FY23) of this $200 million accelerated five-year pavement maintenance program with proposed new asphalt mill and overlay projects.
Other Information
Phoenix's Street Network
Phoenix has a comprehensive roadway network of more than 4,860 miles of public streets. Phoenix’s roadway network is made up of arterial, collector, and local streets. Arterials are major streets, which are typically the major north/south and east/west transportation corridors spaced at each mile. Collectors are important mid-level transportation corridors, which are generally on the 1/2-mile north/south and east/west streets between the arterial streets. Local streets are typically in residential areas, and provide connectivity between the collectors and arterials for local traffic.
Attachment A - Table 1 illustrates the distribution of street classification types, in centerline miles, across the City’s eight council districts.
Pavement Management System and Pavement Condition Index
The foundation of Streets' pavement maintenance program is the use of a comprehensive evaluation system that determines the condition of the roadways to establish priorities of streets to receive maintenance treatments and overlays. This system utilizes field data obtained using a high-tech pavement management vehicle, which measures and records the condition of roads, evaluating them on surface roughness, environmental stresses, and structural condition. Based on the resulting Pavement Condition Index (PCI) rating, which is tracked and mapped in the department’s PCI database, staff uses these objective measurements of roadway conditions to develop an initial list of roads to receive asphalt overlay. Once the pavement maintenance list is developed, the initial list of roads is put through a rigorous coordination review, which includes evaluating the following:
Americans with Disabilities Act (ADA) compliance
Conflicts with other City projects
Right-of-Way concerns
Environmental issues
Utility issues or conflicts
Field visual inspections
Pavement age
Roadway traffic volumes
Alternate pavement treatments
Accelerated Pavement Maintenance
The first phase (FY19 and FY20) of the accelerated pavement maintenance program is currently in progress. Streets staff has been working over the past several months on the development of the second phase (FY21 through FY23) of the program. The identification of arterial and major collector streets to be included in the final three years of the plan for asphalt mill and overlay has been an intensive process including the following steps:
Collected street PCI information was used to identify streets that would be likely candidates.
Field evaluations were then conducted to confirm or negate the inclusion of candidate streets.
A comprehensive community engagement process was conducted to collect public input and feedback on what streets should be included in the program.
Through this comprehensive process over the past several months, new streets were identified to receive asphalt mill and overlay treatments in the final three years (FY21 through FY23) of the five-year plan (FY19 through FY23). Although the $200 million acceleration of Streets T2050 funds is focused on arterial and major collector streets, Streets staff has also shifted its HURF-funded pavement maintenance projects, which are focused on our local street network. This shift does not change the total amount of HURF funds in the five-year program, but does increase annual funding of local street maintenance over the first two years of the plan. The proposed Pavement Maintenance Program, shown in Attachment A - Table 2, reflects the $200 million T2050 acceleration and the HURF funding shift, and includes the budget and street miles for all types of pavement maintenance treatments. It also includes information on the original budget and planned treatment miles prior to the approval of the $200 million accelerated plan.
Maps showing proposed locations for asphalt mill and overlay treatments, along with the results of the community engagement process are shown in Attachment B. In addition, lists of the street asphalt mill and overlay projects included in each fiscal year are shown in Attachment C. The breakdown of pavement treatment types by Council District is shown in Attachment D.
All proposed pavement maintenance projects have been or will be put through a thorough conflict review process. This includes reviewing and coordinating with other planned Streets capital improvement projects, Water Services Department projects, planned private developments, and private utility projects. The conflict review process is critical to ensuring that street pavement is not cut following an asphalt mill and overlay project. In the event of a conflict, the schedule of streets will be adjusted within the plan to accommodate as best as possible. In the event a conflict pushes a street out of the current five-year plan, it will remain as a proposed project in a future year to be completed as soon as practical.
Any changes to the proposed Pavement Maintenance Program will be reflected and communicated in regular annual updates. These changes are typically driven by changes in budgets, street condition, or potential new conflicts that occur throughout the life of the plan.
Community Engagement Process
Streets staff reached out citywide to numerous community groups, block watch organizations, homeowners associations, business groups, community events, and neighborhood organizations and offered to present on the accelerated pavement maintenance program, including information on how to provide input. Through March 31, 2019, Streets staff presented at 64 community meetings, which included an estimated 7,300 residents.
The community engagement process provided various tools for the public to learn about the accelerated pavement maintenance program and to provide their feedback. These tools included:
Accelerated Pavement Maintenance Program website that provided comprehensive information.
Interactive, internet-based mapping tool, allowing the public to provide input on the condition of streets on a map of the city. This included points for specific defects on the road to help direct staff to any issues that could immediately be resolved. Through March 31, 2019, over 4,300 points, or pin-drops, were placed on the map by individuals during the two-month input process.
Dedicated email address and phone number for the public to ask questions and provide input on streets that need maintenance. In total, 212 emails were received.
Public input forms were provided at the community meetings that could be mailed in or provided to those not comfortable using the mapping tool or who may not have access to email.
Direct interaction with staff at the public meetings also allowed residents to bring up other street-related issues to be addressed.
Since April 1, 2019, Streets staff has continued to attend, present at and collect public input at community meetings. The input gathered at these meetings will be retained for future use in modifications or adjustments to the pavement maintenance program.
Concurrence/Previous Council Action
On Oct. 3, 2018, the City Council directed staff to develop a plan to expend $200 million over the next five years to accelerate pavement maintenance on arterial and major collector streets.
On December 12, 2018, the City Council approved the first phase of the accelerated pavement maintenance plan, which was to complete in FY19 and FY20 the previously approved asphalt mill and overlay treatments scheduled for FY20 through FY23.
On March 6, 2019, the City Council approved authorization to issue $200 million of debt obligations with Streets T2050 funding to fund the accelerated pavement program.
On Apr. 25, 2019, the Citizen's Transit Commission (CTC) recommended Aviation and Transportation Subcommittee and Council approval of the proposed T2050-funded Five-Year Pavement Maintenance Program for FY19 - FY23 by a vote of 12-0, with the expectation that staff return to the CTC at a future date to provide more information about the miles of bike lanes that will be included as part of this accelerated effort, as well as information on the financing of the accelerated program.
Recommendation
Staff requests the Aviation and Transportation Subcommittee recommend City Council approval of the proposed T2050-funded Five-Year Pavement Maintenance Program for FY19-FY23.
