Plain English Summary

AI-GENERATED
Redraws the Big Cypress Basin's boundary using a 2021 study.

At 11:59 p.m. on July 1, 2026, the water management district's board must redraw the Big Cypress Basin's boundary to match a 2021 scientific study, but may only include counties with at least a quarter of their area inside that line.

The governing board's membership is fixed at eight: six people from Collier County and two from Lee County, all living within the basin, replacing an older rule that only required at least five members living somewhere in the area.

Basin property taxes must now be spent only in the county where they were collected, funding flood control projects and maintenance there rather than being pooled for use anywhere in the wider basin.

KEY PROVISIONS
§ 1 Boundary redrawn to match a 2021 scientific delineation study majors. 373.0693(9)

AIAt 11:59 p.m. on July 1, 2026, the water management district's governing board must set the Big Cypress Basin's boundary to the scientific line recommended in a January 2021 study, replacing the original 1976 boundary description.

“shall establish the boundary of the Big Cypress Basin as the scientific boundary recommended in the Big Cypress Basin Boundary Delineation study” bill text, line 43 →
§ 2 Counties need a 25 percent overlap to join the basin majors. 373.0693(9)

AIA county may be folded into the redrawn Big Cypress Basin only if at least a quarter of its own jurisdiction falls inside the study's recommended boundary line, screening out counties with only a marginal sliver inside the basin.

“may include only counties that have at least 25 percent of their jurisdictions delineated within the boundary” bill text, line 47 →
§ 3 Basin taxes must be spent in the county where collected majors. 373.503(3)(b)

AIThe water management district must ensure basin ad valorem taxes collected in a given county are spent only on flood-control projects, operations, and maintenance within that same county, rather than pooled for use anywhere in the wider Big Cypress Basin.

“are used for projects and flood control operations and maintenance within the counties in which such taxes were collected” bill text, line 74 →
§ 4 Fixes board at 8 seats split between Collier and Lee counties moderates. 373.0693(9)

AIThe Governor must appoint exactly six board members from Collier County and two from Lee County, all residing within the basin, replacing an open-ended rule that required only at least five members living somewhere in the basin area with no county-specific allocation.

“six persons from Collier County and two persons from Lee County who reside within the Big Cypress Basin”
