(a) At any time after the establishment of a tourism destination marketing district pursuant to this chapter, the tourism destination marketing district plan upon which the establishment was based may, upon the recommendation of the management entity's tourism destination marketing district committee be amended by the municipal governing body of the lead jurisdiction after compliance with the procedures set forth in this section; provided, however, that a lead jurisdiction may not approve amendments to the boundaries of a tourism destination marketing district that include the territorial jurisdiction of a city or town not yet included in the tourism destination marketing district without the consent, by vote, from such other city or town's local municipal governing body.

Amendments to the tourism destination marketing district plan shall be subject to the approval of the municipal governing body of the lead jurisdiction for the following: (i) providing for additional supplemental services that affect more than 25 per cent of the total annual budget; (ii) incurring indebtedness; (iii) changing the special assessment methodology, management entity or tourism destination marketing district committee; or (iv) change the tourism destination marketing district boundaries; provided, however, that said municipal governing body, after a public hearing, determines that it is in the public interest to adopt said amendments.
