All requests for amendments to the text of this chapter, or for changes in zoning district boundaries, initiated by other than the Board of Selectmen, by petition, or the Planning Board, shall be accompanied by a non-refundable application fee as set by the Board of Selectmen and shall be submitted to the Office of Planning and Development. No such request or proposal shall be referred to the Board of Selectmen or Planning Board unless and until the fee is paid. In addition, the applicant shall pay all expenses in connection with the requested amendment application by submitting funds for deposit into a Town-established escrow account. These expenses may include, but are not limited to, costs associated with amending the Official Zone Map, printing and copying costs, website updates, postage, and public hearing ads. Any funds that remain in the escrow account once all expenses associated with the amendment application have been paid shall be refunded to the applicant.
