(1) At least once every 7 years, each local government shall evaluate its comprehensive plan to determine if plan amendments are necessary to reflect a minimum planning period of at least 10 years as provided in s. 163.3177(5) or to reflect changes in state requirements in this part since the last update of the comprehensive plan, and notify the state land planning agency as to its determination. The notification must include a separate affidavit, signed by the chair of the governing body of the county or the mayor of the municipality, attesting that all elements of its comprehensive plan comply with this subsection. The affidavit must also include a certification that the adopted comprehensive plan contains the minimum planning period of 10 years, as provided in s. 163.3177(5), and must cite the source and date of the population projections used in establishing the 10-year planning period. (2) If the local government determines amendments to its comprehensive plan are necessary to reflect changes in state requirements, the local government must prepare and transmit within 1 year such plan amendment or amendments for review pursuant to s. 163.3184. (3) Local governments shall comprehensively evaluate and, as necessary, update comprehensive plans to reflect changes in local conditions. Plan amendments transmitted pursuant to this section must be reviewed pursuant to s. 163.3184(4). Updates to the required elements and optional elements of the comprehensive plan must be processed in the same plan amendment cycle. (4) If a local government fails to submit the letter and affidavit prescribed by subsection (1) or to transmit the update to its plan pursuant to subsection (3) within 1 year after the date the letter was transmitted to the state land planning agency, it may not initiate or adopt any publicly initiated plan amendments to its comprehensive plan until such time as it complies with this section, unless otherwise required by general law. This prohibition on plan amendments does not apply to privately initiated plan amendments. The failure of the local government to timely update its plan may not be the basis for the denial of privately initiated comprehensive plan amendments.
(5) If it is determined that a local government has failed to update its comprehensive plan pursuant to this section, the state land planning agency must provide the required population projections that must be used by the local government to update the comprehensive plan. The local government shall initiate an update to its comprehensive plan within 3 months following the receipt of the population projections and must transmit the update within 12 months. If the state land planning agency finds the update is not in compliance, it must establish the timeline to address the deficiencies, not to exceed an additional 12-month period. If the update is challenged by a third party, the local government may seek approval from the state land planning agency to process publicly initiated plan amendments that are necessary to accommodate population growth during the pendency of the litigation. During the update process, the local government may provide alternative population projections based on professionally accepted methodologies, but only if those population projections exceed the population projections provided by the state land planning agency and only if the update is completed within the timeframe set forth in this subsection.
(6) The state land planning agency may not adopt rules to implement this section, other than procedural rules or a schedule indicating when local governments must comply with the requirements of this section.
