Needham outlines upgrades to snow-and-ice operations, including proposed brine maker and pavement sensors

Public Works staff reported improved staffing and contractor availability this winter and outlined planned equipment and technology investments intended to make snow operations more efficient.

The director said the town is only down about four FTEs in operating staff compared with being down as many as 18 a few years ago. Assistant Superintendent Eric Leneghan was credited with outreach that helped re-engage contractors. Staff noted hauling remains subject to state procurement rules under Chapter 30B and that the town is seeking clarification to allow a contractor selection method better suited to hauling operations.

Operations staff described three near-term investments: a brine maker (requested in the FY27 CIP), road-weather information stations, and embedded pavement-temperature sensors. "When we produce our own brine, the rough math is about 10¢ a gallon to produce our own brine," a DPW presenter said, contrasting that with roughly $1.75 per gallon for purchased brine. Staff said pavement temperature—not air temperature—drives treatment choices because salt efficiency declines below roughly 15°F. The department also described adding wing plows to extend plow swaths on selected routes and reallocating larger equipment to residential streets.

On workload and materials, staff reported 11 snow operations so far this season, 4 of which required full plowing, and total seasonal accumulation of 8.4 inches. The town has applied roughly 1,800 tons of salt to date. Officials warned that refreeze/black-ice events require repeated treatments and that salt sometimes is not visible because it must dissolve to become active.

Next steps: the Select Board asked staff to pursue the brine-maker CIP request through town meeting, continue outreach to recruit heavy-equipment contractors, and return with specifics on weather-station siting and anticipated cost savings.
