The Pattern
-
Starts & Stops: 1976–2015 was defined by aborted attempts — withdrawn bills, failed funding, or studies that never moved.
-
Breakthrough: In 2019, the reserve account was finally locked in.
-
Big Spend: 2021 opened the door to Tyler Technologies, moving reassessment into the modern era — but also tied the county to high-cost contracts.
-
Ripple Effect: From 2023 on, reserve dollars began bleeding into other uses — police pay, capital budgets — diluting the very fund meant to stabilize taxes.
-
Today: Appeals, abatements, and penalty relief are front and center. The money is moving faster than the message.
The Bottom Line
Reassessment has always been less about numbers and more about politics. When leaders delayed, homeowners paid later. When they spent, it often went sideways. The record shows this truth: reassessment isn’t a technical issue — it’s a test of trust.
