81-4-310. Annexation into existing herd district. (1) Owners or possessors of land that is contiguous to a herd district may petition to have their property annexed to that district. The petition must be properly signed by the owners or possessors of at least 55% of the affected land and must include the post-office address of all petition signers. The petition must state the outside boundaries and a description of the property to be annexed to the existing district. When the petition is filed with the clerk and recorder in the county in which the existing district lies, the county commissioners of that county shall set a date for hearing protests and verifying petition signatures. The county commissioners shall provide notice of the hearing by publishing the hearing date and a list of the properties proposed to be annexed, at least three times in a newspaper of general circulation in the county, not less than 20 days prior to the hearing date.

(2) At the hearing held pursuant to subsection (1), the county commissioners shall examine the petition and have a map drawn up in order to determine the shape and regularity of the boundaries of the property proposed for annexation. If the county commissioners determine that the boundaries are reasonably regular and symmetrical in shape in relation to the geographical features of the properties proposed for annexation, the county commissioners may declare that those properties are annexed into the existing herd district.

(3) If the county commissioners declare the properties annexed to the existing herd district, they shall give notice of the annexation by four weekly publications in a newspaper of general circulation in the county. Annexation does not become effective until 30 days after the declaration of annexation is made, as provided in subsection (2).
