Consultants: Lewisville's roads largely healthy but long-term keep-up will rise; PCI target set at 85
Summary
Presenters said more than 92% of the city's streets are in satisfactory or good condition, the council's pavement condition index (PCI) target is 85, and long-term keep-up and catch-up spending will increase to maintain or raise that standard.
Consultants told the Lewisville City Council that the city's pavement condition index (PCI) work shows strong system health but also identified funding needed to maintain or improve the network.
Richard Campbell, who led the streets and alleys analysis, said the city's PCI grading and GIS mapping show over 92% of streets fall in the 71–100 PCI range (satisfactory to good) and alleys are over 60% in the same range. "Good news is, you've got over 92% of your system on your streets that are in satisfactory, good condition," Campbell said.
Campbell described how treatments yield smaller PCI gains while full reconstruction adds decades of life. "You can gain another 55, 60 years on your streets by just replacing the road," he said, then explained the economic trade-off: repeated smaller treatments are cheaper short-term but eventually cost more than replacement.
The presentation listed current funding for streets at just over $45,000,000 and modeled a 10-year keep-up average around $42.5 million; consultants estimated an average keep-up-and-catch-up need near $53,000,000 because certain segments will require replacement as they deteriorate. Campbell also confirmed the analysis excludes TxDOT (state) roads and covers only assets the city is responsible for.
Council members asked about assumed escalation rates for maintenance and replacement costs; Campbell said the consultants blended historical engineering escalation with a dampened view of the past 4–5 high-inflation years so the very recent inflation spikes do not unduly drive long-term forecasts.
The council discussed short-term reallocation options to address visible needs (for example, hiring outside contractors to repair street signs or conducting a comprehensive signal-assessment project) while maintaining the long-term PCI target. Consultants cautioned that policy choices (raising or lowering the target PCI for concrete vs. asphalt) materially affect short- and long-term spending needs.
The meeting recessed for lunch before council took action on the presentation.
