TDOT grant-funded pavement study finds county network PCI 52.2; consultants recommend $3M one-time effort and continued preservation funding
Summary
KCI Technologies presented a TDOT-funded pavement condition assessment showing a weighted network PCI of about 52.2. The firm recommended a one-time $3 million funding effort to address the worst segments plus continued annual preservation spending; the commission approved a resolution to accept the study and close the grant.
KCI Technologies presented a county pavement condition assessment paid for through a TDOT transportation planning grant and recommended a short-term $3 million effort to address the worst road segments plus continuation of the county’s existing annual pavement preservation funding.
Liesl Gerthurt of KCI said the firm surveyed about 530 miles of county-maintained pavement and produced a weighted network Pavement Condition Index (PCI) of about 52.2, below the industry average of roughly 70. The study included field measurements of distress types and severities; consultants ran six funding scenarios in PAVER pavement-management software to show how differing annual investments would affect the network over five years.
Why it matters: KCI’s analysis shows the county’s current annual spend of roughly $1.2 million will not materially raise the overall PCI and that deferring work increases long-term backlog and costs. KCI recommended establishing a countywide target PCI, maintaining routine preservation funding, and a complementary one-time targeted investment (their prioritized list totals about $3 million) to address critical segments during the next fiscal year.
What commissioners did: After questions about funding sources, county officials requested staff to review how a one-time effort would be included in the mayor’s forthcoming budget. Commissioners voted to adopt a resolution acknowledging completion of the grant study so the grant can be closed and the final report submitted. Commissioner Beatty made the motion and Commissioner McElhinney seconded; the commission approved by voice vote.
Details: Gerthurt described the data-collection period (field work October–mid January), the PAVER scoring methodology, and the scenarios studied, which ranged from no additional spending to levels that would aim to reach a PCI target of 70. The consultants estimated it would take roughly $17.6 million per year over five years to merely maintain the current average PCI and $23.4 million per year to reach a PCI of 70.
Next steps: The county will consider the study’s recommendations along with other budget priorities; KCI and TDOT representatives said the county should run PAVER updates every 2–3 years and consider one-time funding options (general fund, bonding or grant match) to implement the prioritized repairs.
