Spring Hill straddles the two counties. Williamson County has historically provided ambulance coverage on both sides of the city line, but now wants Maury County to contribute financially for service in its portion of Spring Hill. Williamson County commissioners have approved an 18-month agreement to continue coverage while the counties negotiate.

Maury County Mayor Sheila Butt said her county's Budget Committee has endorsed paying $750,000 for six months while officials plan for future funding. That committee vote is not a final agreement between the counties.

Butt said rising costs led Williamson County to stop subsidizing coverage in the Maury County portion of Spring Hill. "That decision was presented to us in the middle of a budget cycle," she said.

The shorter arrangement would give Maury County time to include the service area in its 2027–2028 budget, Butt said, adding that resident safety will guide the county's decision.

Fitterer said switching to Maury County EMS would increase response times. He noted that Spring Hill's 911 calls go through Williamson County's consolidated dispatch system, so transferring those calls to Maury County would add another layer of delay.

"Spring Hill is supportive of a solution that prioritizes response times and patient care while balancing county fiduciary responsibilities," Fitterer said.

The city is encouraging both counties to put patient care first while managing costs, he added.

Neither mayor's response announced a provider change or specified how much longer ambulance response times could become. Questions remain about the final funding arrangement and how coverage would continue when the current agreement ends.

Williamson Health referred questions about the agreement to county representatives.
