Title
Presentation on the Pavement Management Program for Alameda (Discussion)
Body
To: Members of the Transportation Commission
EXECUTIVE SUMMARY
Staff will present an informational item on the Pavement Management Program for the City of Alameda. Basic pavement concepts, funding considerations, and process for street selection will be presented.
DISCUSSION
The City of Alameda has 128 centerline miles of roadway providing access to all properties and businesses on the island. Maintaining the roadway network is central to the livability and economic vitality of the island. In addition, with a replacement value in excess of $440,000,000, Alameda’s roadway network is one of the City’s most valuable assets. The City’s streets are considered in fair to good condition, however, the Pavement Condition Index (PCI) has fallen from 72 in 2018 to is current value of 68. Years of underinvestment in the paving program have created a deferred maintenance backlog of over $50,000,000.
The City’s pavement management program consists of slurry, and cape seal projects, overlays, and major roadway reconstruction. As part of Public Works three year paving plan, the City has been divided into thirds and projects will rotate throughout the City. At this time, roads within Alameda Point are addressed separately and will be incorporated into the overall program following redevelopment. For the remainder of the island, locations and treatments are finalized early in the year, designed and bid on in the spring, and constructed during the summer. Staff will present some of the many considerations involved in the selection process including street classification (arterial vs. residential), pavement condition, type and nature of the pavement distress, and consideration of available funding.
This major construction program will treat approximately 3.5 or more miles of street per year with asphalt concrete, slurry seal, cape seal, or other rehabilitation method. Work may include repair of underlying material, adjustments to concrete as needed to restore drainage (curbs, gutters, driveways, culverts, curb ramps), and reinstallation of pavement striping.
In addition to the once per year major construction project, City personnel perform other work year-round, including minor pothole patching and ponding repair; master planning; coordination with utility companies; coordination with major subdividers; biennial field inspection of pavement condition; updating the GIS database; yearly reporting to funding sources; and grant acquisition.
Repairs and upgrades will be made in accordance with the City’s Complete Streets Policy, Transportation Element of the General Plan, ADA Transition Plan, Bicycle Master Plan, and Pedestrian Master Plan.
FINANCIAL IMPACT
Funds are appropriated to the Pavement Management Program as part of the biennial Capital Budget. Funding comes from a variety of sources including gas taxes, Measures B, BB, and F, and transfers from the integrated waste and sewer funds. In addition, the City sometimes receives grants through Caltrans or other sources for specific streets, which will be constructed as smaller, separate projects. The recent passage of Alameda County Measure BB and SB-1, the Road Repair and Accountability Act have significantly increased the funding available to maintain our roads. Including projections for the upcoming 2019-2021 Capital Budget, funding has averaged approximately $4,000,000 per year since 2016. It is estimated that approximately $6 million of funding per year is required to maintain our existing PCI and approximately $10 million per year to improve our PCI to 73 in five years.
