The bill amends Sections 11-106-3, 11-106-4, and 11-106-6 of the Code of Alabama 1975 to revise the definition of "military installation" and establish new requirements for constructing tall structures near these installations. The definition of "military installation" is updated to include any land area under the jurisdiction of the U.S. Department of Defense, regardless of size, while excluding facilities primarily used for civil works. Additionally, the bill mandates that individuals must obtain approval from local governments before constructing any tall structure within two miles of a military installation. Local governments are also granted the authority to seek injunctive relief against unauthorized construction.

Key changes include the insertion of new language that prohibits the commencement of construction on tall structures without prior local government approval and the requirement for applicants to provide documentation of compliance with federal aviation regulations. The bill also clarifies that local governments must notify military installations of any local impact issues and outlines the necessary documentation for wind energy facilities. The act is set to take effect on October 1, 2025.
