TACIR staff: Greenbelt valuation can either raise or lower county fiscal capacity depending on local context

TACIR Research Director Michael Mount briefed the Education Finance Subcommittee on how Greenbelt (use-value) property valuations interact with the commission's fiscal-capacity model and said the overall effect on a county's calculated fiscal capacity is not uniform.

Mount explained Tennessee law permits property owners to apply for Greenbelt classification so qualifying agricultural, forest or open-space land is assessed on use value rather than market value. "Once a property qualifies for greenbelt status, it is assessed based on its current use," Mount said, and the resulting lower assessment "supports land conservation and agricultural sustainability, but also results in lower property tax base."

Mount reviewed statutory qualification thresholds the staff cited: agricultural land generally requires a minimum 15-acre tract (with a 10-acre additional-tract rule), forest land requires a 15-acre minimum under a forest-management plan, and open-space land requires a minimum three-acre tract within a preservation plan. He also summarized findings from TACIR's 2009 Greenbelt report, which identified several options (none adopted) to limit or recapture Greenbelt subsidies, such as minimum valuation floors, rollback-interest adjustments, and inspector authority for eligibility verification.

Mount said the Greenbelt effect in the fiscal-capacity model is twofold: lowering residential or farm assessment reduces the property-tax base and reduces the residential-and-farm share of total assessments, and those two effects can partially offset each other. "Designating a farm or residential property as Greenbelt in the county can increase or decrease the county's fiscal capacity in TACIR's model," Mount said.

Committee members raised policy trade-offs. One member urged caution about tightening eligibility and suggested placing use conditions or public-benefit requirements (educational visits, conservation easements) rather than automatic rollback recapture. Mount and Lippert noted the staff's primary role in this subcommittee was to show how Greenbelt rules interact with the fiscal-capacity model; staff did not propose specific statutory changes at this meeting. Mount confirmed the 2009 report options had not been adopted.

Ending: TACIR staff said Greenbelt remains a recurring topic and that the commission could be asked to revisit the 2009 recommendations if the full commission requests further study.
