SUBJECT: FY2024 PAVEMENT MANAGEMENT PROJECTS
 
STAFF PRESENTER(S): Brian Harvel, Streets Superintendent

SUMMARY

To gain City Council approval of expenditures up to $6,353,728 for FY2024 pavement management projects.

STRATEGIC PLAN ALIGNMENT

     

RECOMMENDATION

Approve expenditures in the amount of $6,353,728 to complete FY2024 pavement management projects in various locations throughout the city. (Brian Harvel, Streets Superintendent)

FISCAL IMPACT

The FY2024 pavement management program budget includes $3,697,228 in Arizona Highway User Revenue Fund (HURF) and General Funds in the Public Works Operating budget as well as $2,656,500 in one-time Capital Improvement Program (CIP) funding.  The CIP funding is specifically for the reconstruction of asphalt roadways in the Historic Goodyear community.  Identified in Table 1 are the FY2024 pavement management projects categorized by type of pavement treatment and the budget associated with each project type.

BACKGROUND AND PREVIOUS ACTIONS

In 2014, the City’s average Pavement Condition Index (PCI) was 68.1.  PCI measures the condition of the City’s roadways, on a scale of 1 to 100.  The 2014 PCI of 68.1 served as a baseline data point as the City invested more resources to improve the condition of the City’s roadways.  These steps have seen significant results with the City’s most recent PCI of 76.4 in 2023.  Table 2 shows the City’s PCI trends over the past ten years.  Most notable is the steady increase in the City’s PCI, and that the PCI has been relatively stable over the last four years. City staff seeks to maintain our average PCI between 76 and 78, and our FY24 pavement management program is focused on this goal, in coordination with the City’s street improvement CIP projects, private development and utility projects, and the continued development of unimproved roads in the city.

STAFF ANALYSIS

The projects contained within the proposed FY2024 pavement management program will improve 112 lane-miles of street pavement, which accounts for approximately 10% of the City’s 1,136 lane miles.

A successful and comprehensive pavement maintenance program includes a variety of pavement treatments types, and utilizing the right pavement treatment for the right streets and the right pavement condition.  The proposed FY2024 pavement maintenance program includes various pavement preservation treatment types, and a description of each is provided below, followed by a list of roadways or neighborhoods recommended for the designated pavement treatment:

 
1. Slurry Seal – A product that is commonly used on residential roads and is effective at correcting or inhibiting raveling and oxidation of the pavement surface, improving surface friction, sealing the pavement surface, and filling minor surface irregularities up to 0.5 inches deep.  Slurry seal typically lasts 5 - 7 years.  FY2024 slurry seal projects are scheduled in these neighborhoods:
 
  • Sereno
  • Morado
  • Covina
  • Kinhali
  • Artherton Commons
  • Calappa
  • Palmetto Passage
  • Coquito Trails
  • Darian Court
  • Hesper Knoll
  • Trianda Terrace
  • Cabada Corners
  • Mazari Cove
  • Legend
  • Avalon North
  • Ridgeview Point
  • Mesquite Ridge
  • Arroyo Vista
  • Sonoran Springs
  • Saguaro Canyon
2. Micro-Surfacing – A product that is commonly used on arterial and collector roads and is effective at correcting or inhibiting raveling and oxidation of the pavement surface, improving surface friction, sealing the pavement surface, and filling minor surface irregularities and wheel ruts up to ~1.25 inches deep, even though the overall surface application is ~0.5 inches.  Micro-surfacing typically lasts 5 - 7 years.  FY2024 micro-surfacing projects are:
 
  • Bullard Ave: Encanto Blvd to Indian School Rd
  • Indian School Rd: SR303 to Old Litchfield Rd
  • Pebble Creek Pkwy: McDowell Road to Charles Blvd
  • Wigwam Blvd: Indian School Rd to Litchfield Rd
3. Mill and Overlay – A process in which the first 1.5 inches of pavement is milled off and replaced with 1.5 inches of fresh asphalt.   This is commonly used on roads where the surface has deteriorated to a point where other treatments will no longer be effective.  This will extend the life of the pavement and reset the treatment process of the roadway.  The FY2024 mill and overlay project is:
 
  • Lower Buckeye Pkwy from Cotton Lane to West of 173rd Ave.
4.  Residential Asphalt Reconstruction – This process is the complete removal of the roadway and replacement with new asphalt.  This is completed when the asphalt roadway has reached the end of its useful life.  This process will restart the pavement life cycle and could last upwards of 30 years with proper pavement preservation. The FY2024 asphalt reconstruction project is:
 
  • Historic Goodyear Pavement Rehabilitation (CIP Project # 60121)

5. ADA Ramp Improvements – ADA ramp improvements, located on roadways receiving treatments that alter the road structure (Micro Seals, Mill and Overlays, Reconstruction) are required for such projects in order to comply with the current federal ADA guidelines. The FY2024 ADA improvements will replace the ramp structures where needed, and/or add truncated domes, depending on the location.


The FY2024 pavement maintenance projects will be completed utilizing existing city contracts with the following companies:

Viasun Corporation
South West Slurry Seal
Sunland Asphalt
