The bill amends chapter 2013-256 of the Laws of Florida, specifically concerning the Fort Pierce Farms Water Control District in St. Lucie County. It increases the maximum annual maintenance tax from $25 to $60 per acre and introduces a cap on annual assessment rate increases, limiting them to a maximum of 10 percent compared to the previous year's rate. Additionally, the bill stipulates that the maximum allowable maintenance tax will adjust annually based on the Consumer Price Index for All Urban Consumers, as calculated by the U.S. Department of Labor.

Furthermore, the bill mandates that a referendum be conducted by the Supervisor of Elections of St. Lucie County on or before December 31, 2026, allowing landowners within the district to vote on these changes. The act will only take effect if approved by a majority of the voting landowners in the referendum, although the sections regarding the referendum and the act's effective date will become law immediately upon passage.
