Engineer outlines Snoqualmie pavement-management plan and 2026 resurfacing priorities
Summary
Engineer Hind Ahmed presented the city’s pavement-management approach using PCI/BCI data and StreetSaver software, explained the prioritization logic (keeping good roads good), and highlighted Newton Street as a candidate for full reconstruction with drainage, sidewalk and water-main work.
Engineer Hind Ahmed presented the city of Snoqualmie’s pavement-management program, describing how visual surveys and 3D imaging are converted into a pavement condition index (PCI/BCI), how the StreetSaver software models budget scenarios, and how the city prioritizes treatments to preserve network condition.
Ahmed explained that the program prioritizes cost-effectiveness and functional class (arterials/collectors get higher priority) and that the software can either optimize within an available biennium budget or compute the budget needed to meet a target PCI. He told the committee the city-wide PCI has stayed above 70 since 2021 and attributed some year-to-year changes to large overlay projects and the addition of new roadways.
The presentation clarified treatment types and when they are used: slurry seal for low-cost preservation, grind-and-overlay for roads in good condition, structural patching where there are alligator cracks or utility disturbance, and full reconstruction where subgrade/ drainage problems exist. Ahmed noted Newton Street will require a reconstruction that includes drainage improvements, sidewalk connections to downtown and water-main replacement, not just resurfacing.
Council members asked whether the recent flood and wet-season freeze-thaw cycles had created new urgent pavement needs; staff said higher groundwater and poor soils downtown accelerate pavement failures and that some projects will draw on specialized funds (utility-infrastructure fund, Kimbell Creek drainage fund) to spread costs.
Staff said the city hires a contractor to perform 3D imaging and updates the PCI every five years, using annual predictions from the software between surveys. The committee asked for the material to be presented to the full council; staff agreed to make the presentation available on a webpage for residents.
No formal council action was taken; the presentation was informational and intended to guide future resurfacing investments.
