This bill amends the existing law governing the Port St. Joe Port Authority to expand its jurisdiction to include Franklin, Gadsden, Gulf, and Liberty Counties. It revises the membership structure of the authority's governing body, which will now consist of five commissioners appointed by the Governor. The new appointments will include two members from Gulf County and one member each from Franklin, Gadsden, and Liberty Counties. The bill also establishes staggered terms for the commissioners to ensure continuity in governance.

Additionally, the bill outlines the powers and limitations of the Port St. Joe Port Authority, emphasizing that it cannot bind or commit the involved counties or the City of Port St. Joe to any liabilities. It allows for the appropriation of funds from the newly included counties to support the authority's operations. The effective date of the act is set to be upon its passage into law.
