(a) The five-year vesting period is extended to the development concept vesting period with respect to the development concept if: (i) The land development will be wholly contained within a community enhancement district; and (ii) either:

(A) Such community enhancement district has been created and is in existence, and such facts have been communicated to the planning commission, at the time the planning commission approves the subject land development plan and plat (whether such plan and plat is denominated final, preliminary, phased preliminary, concept or otherwise); or

(B) Such community enhancement district is created after the initial approval of the subject land development plan and plat and the planning commission subsequently ratifies the approval of such plan and plat with the knowledge of the existence of the community enhancement district; and (iii) assessment bonds or tax increment financing obligations payable from or secured by, in whole, or in part, assessments against real property located within the district are issued within the five-year vesting period.

(b) Nothing herein shall be deemed to extend or otherwise modify the five-year vesting period with respect to items other than those included in the development concept.

(c) When a land development will be wholly contained within a community enhancement district, a land development plan and plat that otherwise pertains to and seeks approval of only a portion or phase of the land development may also contain the development concept for a greater portion, multiple phases or the entirety of the land development if the plan and plat expressly so provides. Approval of a land development plan and plat by the planning commission constitutes approval of, and the establishment of a vested property right in, the entire development concept contained in the land development plan and plat.

(d) This section shall apply to all community enhancement districts, regardless of whether created prior or subsequent to enactment of this section.
