Marion County commissioners back landfill expansion as staff refines rate and bonding options

Marion County solid-waste staff and consultants told the Board of County Commissioners at a workshop that the county must choose a path to replace shrinking out-of-county disposal capacity and shore up the fund that pays for disposal, operations and storm debris response.

"Today, we're gonna talk about the future of solid waste disposal options for Marion County," Solid Waste Director Mark Johnson told the commissioners, opening a presentation that summarized current airspace purchases, projected tonnage and options to transfer or landfill locally.

Why it matters: Marion County prepaid for disposal airspace at the Heart of Florida landfill and has consumed roughly 36% of that purchase; staff estimates the county will use about 207,000 tons this year. At the long-term growth scenario used in the financial models (1.56% annually) staff said the county would exhaust Heart of Florida airspace around fiscal 2031; under recent short-term growth rates near 7% the depletion could come a year earlier.

The board's discussion weighed two broad strategies. Transfer stations with third-party disposal would rely on hauling county waste out of the county; county staff said turnkey third-party transfer-and-dispose pricing in recent RFP responses is roughly comparable to current baseline disposal rates but carries higher operating costs and less operational control.
