Specifically, it seeks to include the Mack Post Jr. Subdivision, which consists of Lots 1 through 12 as per the amended plat recorded on March 26, 1993. This area, located in the SE 1/4 of the NW 1/4 of Section 34, Township 18N, Range 17E, encompasses approximately 7 acres. The bill also stipulates that a map detailing the proposed changes will be available for public inspection in the Office of the Judge of Probate in Elmore County.

The act is set to take effect on June 1, 2024, following its passage in the House on May 2, 2024, and in the Senate on May 8, 2024. There are no deletions from current law mentioned in the text, but the new legal language includes the insertion of the term "Enrolled" at the beginning of the act and the specific details regarding the annexation of the Mack Post Jr. Subdivision.
