The proposed bill establishes the "Bocilla Islands Chain Conservation District" in Charlotte County, aimed at preserving the fragile barrier islands, including Thornton Key, Palm Island, Knight Island, Don Pedro Island, and Little Gasparilla Island. The bill includes legislative findings that highlight the islands' natural beauty and biodiversity, emphasizing the need for conservation. It restricts the density of dwelling units to one per acre or per platted lot, limits commercial and industrial land use to areas zoned for such purposes before the act's effective date, and imposes height restrictions on buildings. Additionally, it prohibits the expansion of infrastructure unless necessary for public health and safety.

The act also clarifies that it does not repeal existing local government comprehensive plans or regulations but prevails where its provisions are more restrictive. Property owners within the district are granted the right to enforce the act through civil proceedings without needing to prove specific adverse effects on their property rights. The bill mandates that a certified copy be recorded in the public records of Charlotte County and takes effect upon becoming law.
