County unveils pavement management portal and shifts to multilayer preservation to stretch road dollars

Public works staff and consultants demonstrated a new pavement‑management transparency portal and outlined a preservation‑first strategy intended to maximize the county’s resurfacing budget.

Walt Eastman and staff said the county’s optimization model recommends multilayer surface treatments for many local roads that are near failure. The recommended preservation technique costs roughly $70,000 per mile and would return 5–10 years of useful life; in contrast, full mill‑and‑pave reconstruction costs about $340,000 per mile. Using preservation where appropriate, Eastman said, increases the annual treated mileage the county can cover from roughly 70 miles to around 200 miles.

The portal: staff previewed an interactive web dashboard showing each road segment’s condition score (PCI), last treatment year, recommended treatment type and backlog estimates. A FAQ and video materials will accompany the portal, which staff said will be public after the presentation.

Board debate and equity concerns: some commissioners warned unconstrained optimization could mean some roads never receive full reconstruction, raising equity issues for neighborhoods that are already underserved. Staff and the chair reminded the board that the commission previously directed staff to run the model unconstrained in order to maximize system‑wide lifecycle benefit, and that the model can be adjusted to reflect policy constraints.

Next steps: staff expects the first group of multilayer preservation projects to be out by the end of the month and estimated a roughly six‑month window to roll the initial contract work.
