The bill amends the legislation governing the St. Lucie County Mosquito Control District by revising its district boundaries. It removes the term "wholly" from the description of the district's location and expands the boundaries to include various sections of Townships 34, 35, 36, and 37 South across multiple ranges, covering approximately 287,827.904 acres. The specific sections and ranges included in the district are detailed through a series of insertions.

Furthermore, the bill mandates a referendum to be held on November 3, 2026, during the General Election, allowing qualified electors in the newly proposed areas to vote on whether the district should be authorized to provide services and exercise powers as outlined in its charter. The bill will take effect upon approval by a majority vote of the qualified electors in the proposed areas, while the sections regarding the referendum will take effect immediately upon becoming law. Additionally, it streamlines the legal language related to the geographic description of the affected areas, focusing on the referendum process.
