County awards traprock contract at $58/ton; public works and counsel discuss increased windshield claims
Summary
Leavenworth County awarded a 2025–26 traprock supply contract to New Frontier Materials at $58 per ton. Public works said prior material changes produced large savings but staff and counsel discussed an uptick in broken-windshield claims and liability considerations tied to application practices and weather.
Leavenworth County commissioners approved a bid award to New Frontier Materials for traprock at $58 per ton for the 2025–26 season and heard an extended staff briefing on material performance and public-claims trends.
Public works staff said switching to traprock in a prior year produced substantial savings — staff cited roughly $1.2 million in fiscal-year savings — and described traprock as a harder, heavier aggregate that adheres to surfaces better. "This material is harder and heavier, and it does appear to adhere to the surface better," the presenter said.
Public works also reported a rise in vehicle-damage claims after some traprock applications, noting an increase in broken-windshield claims compared with earlier seasons. Staff said most claims fell in the $500–$700 range, with a few higher outliers on certain imported vehicles; the department estimated mid‑40s claims this season based on available reporting.
County legal counsel reviewed liability principles for roadway claims, emphasizing that "generally the county is not the insurer of the roadway" and that liability typically requires showing the county directly caused the damage or was on notice and failed to cure a hazard in a reasonable time. Counsel said the county had paid certain claims in specific circumstances after reviewing those cases but that routine rock-on-road claims are uncommon bases for county payments.
Staff told the board they had identified mitigation steps and revised application practices intended to reduce loose aggregate and breakage, and public works committed to reporting on claims trends going forward. The board approved the traprock award while instructing staff to monitor claims and adjust practices as needed.
