The Township Clerk shall place the review deposit escrow fee required by the foregoing provisions in a special account and shall charge all such costs against the same. The Township shall make all the payments to professionals for services rendered to the Township for review of applications for development, review and preparation of documents and other services rendered in administrative review response to the development application submitted. All payments charged to the deposit shall be pursuant to vouchers from the professionals, stating the hours spent, the hourly rate and the expenses incurred. The Township shall, within 45 days following receipt of a written request from the developer, render a written final accounting to the developer on the uses to which the deposit was put. Thereafter, the Township shall, upon written request, provide copies of the vouchers to the developer. At the completion of administration of the development application, including the determination by the Board and its professionals that the conditions, if any, attending the approval of the application have been satisfied, any remaining balance of the review escrow deposit shall be returned to the applicant upon written request. If the cost of the review services exceeds or is anticipated to exceed the amount of the review escrow deposit, sufficient additional funds shall be deposited before final action is taken on the application. A fee shall be separately paid as required by the ordinances of the Township of Harmony in an application involving a subdivision or site plan review.
