House Bill 4093 amends the charter of the Fellsmere Water Control District, changing its status from an independent district to a dependent district of Indian River County. This transition designates the Board of County Commissioners of Indian River County as the new governing body, replacing the previous Board of Supervisors. The bill also significantly reduces the district's geographic area from approximately 34,441 acres to 11,652 acres and introduces new maintenance responsibilities for specific canals, which will be partially managed by the forthcoming Headwaters Water Control District.

Additionally, the bill revises the legal descriptions related to the "Plat of Fellsmere Farms Company's Subdivision of Unsurveyed Township 31 South, Range 36 East," by deleting outdated and redundant legal language to clarify property boundaries and rights of way. It establishes guidelines for public access to district records and outlines the relationship between the Fellsmere Water Control District and the Headwaters Water Control District, including shared maintenance responsibilities. The changes are set to take effect on October 1, 2026.
