County Engineer Angie Kirsten told the board on June 17 she presented a resolution to approve pricing for fiscal year 2026 road rock and ice-control sand after soliciting quotes from Scott County aggregate suppliers and nearby quarries. ‘‘In fiscal 24, we placed approximately 72,000 tons of road rock to surface our gravel roads, and that was at a total cost of $934,000,’’ Kirsten said.
Kirsten said quarry selection and purchase quantities are based on the lowest hauled-in-place cost; that hauling and placement labor are included in the referenced cost figure; and that additional rock is used for shoulder maintenance, road repairs and erosion control. She told supervisors that although listed prices from quarries rose across the board, the county considers both material type and haul cost when selecting a supplier for each location.
Supervisor Jean asked why Riverstone’s price was lower than Linwood Mining’s and whether larger purchases from the cheaper quarry would be feasible; Kirsten replied that haul distance and placement costs can make Linwood cheaper for some parts of the county despite higher base price. Jean added that ‘‘the type of rock is way different’’ and said she prefers Linwood when liming fields because of its lasting ability; Kirsten said different aggregates have differing characteristics and the county uses quarry products it finds suitable for road use.
Kirsten’s presentation requested approval of the resolution; the transcript records discussion but no final recorded vote at the Committee of the Whole meeting.
