1(1) 2The several incorporated municipalities and counties shall have power and responsibility:13(a) 14To plan for their future development and growth.
22(b) 23To adopt and amend comprehensive plans, or elements or portions thereof, to guide their future development and growth.
41(c) 42To implement adopted or amended comprehensive plans by the adoption of appropriate land development regulations or elements thereof.
60(d) 61To establish, support, and maintain administrative instruments and procedures to carry out the provisions and purposes of this act.
80The powers and authority set out in this act may be employed by municipalities and counties individually or jointly by mutual agreement in accord with this act and in such combinations as their common interests may dictate and require.
119(2) 120Each local government shall maintain a comprehensive plan of the type and in the manner set out in this part or prepare amendments to its existing comprehensive plan to conform it to the requirements of this part and in the manner set out in this part.
166(3) 167A municipality established after the effective date of this act shall, within 1 year after incorporation, establish a local planning agency, pursuant to s. 191163.3174, 192and prepare and adopt a comprehensive plan of the type and in the manner set out in this act within 3 years after the date of such incorporation. A county comprehensive plan is controlling until the municipality adopts a comprehensive plan in accordance with this act. A comprehensive plan adopted after January 1, 2019, and all land development regulations adopted to implement the comprehensive plan must incorporate each development order existing before the comprehensive plan’s effective date, may not impair the completion of a development in accordance with such existing development order, and must vest the density and intensity approved by such development order existing on the effective date of the comprehensive plan without limitation or modification. 309(4) 310Any comprehensive plan, or element or portion thereof, adopted pursuant to this act, which but for its adoption after the deadlines established pursuant to previous versions of this act would have been valid, shall be valid.
346(5) 347Nothing in this act shall limit or modify the rights of any person to complete any development that has been authorized as a development of regional impact pursuant to chapter 380 or who has been issued a final local development order and development has commenced and is continuing in good faith.
398(6) 399The Reedy Creek Improvement District shall exercise the authority of this part as it applies to municipalities, consistent with the legislative act under which it was established, for the total area under its jurisdiction.
448(8)(a) 449An initiative or referendum process in regard to any development order is prohibited.
462(b) 463An initiative or referendum process in regard to any local comprehensive plan amendment or map amendment is prohibited unless it is expressly authorized by specific language in a local government charter that was lawful and in effect on June 1, 2011. A general local government charter provision for an initiative or referendum process is not sufficient.
519(c) 520It is the intent of the Legislature that initiative and referendum be prohibited in regard to any development order. It is the intent of the Legislature that initiative and referendum be prohibited in regard to any local comprehensive plan amendment or map amendment, except as specifically and narrowly allowed by paragraph (b). Therefore, the prohibition on initiative and referendum stated in paragraphs (a) and (b) is remedial in nature and applies retroactively to any initiative or referendum process commenced after June 1, 2011, and any such initiative or referendum process commenced or completed thereafter is deemed null and void and of no legal force and effect.
626(9) 627Each local government shall address in its comprehensive plan, as enumerated in this chapter, the water supply sources necessary to meet and achieve the existing and projected water use demand for the established planning period, considering the applicable plan developed pursuant to s. 670373.709671. 672(10)(a) 673If a local government grants a development order pursuant to its adopted land development regulations and the order is not the subject of a pending appeal and the timeframe for filing an appeal has expired, the development order may not be invalidated by a subsequent judicial determination that such land development regulations, or any portion thereof that is relevant to the development order, are invalid because of a deficiency in the approval standards.
746(b) 747This subsection does not preclude or affect the timely institution of any other remedy available at law or equity, including a common law writ of certiorari proceeding pursuant to Rule 9.190, Florida Rules of Appellate Procedure, or an original proceeding pursuant to s. 790163.3215, 791as applicable.
