  Existing jurisdictions, including those involving airports, mass transit, river bridges, waste disposal systems, and intermodal water ports within their jurisdictional boundaries, are protected from incorporation by the authority and shall not be incorporated in the authority except by their respective governing bodies. However, an existing jurisdiction may negotiate with the authority to take over its entire powers, incomes, and debts. The authority may assume the powers, income, and debts for any type of facility authorized by this division.
