Expenses. The applicant shall be responsible for the total cost of environmental reviews determined to be necessary to meet requirements of SEQRA as per 6 NYCRR Part 617.13. The Planning Board may also incur other extraordinary expenses to properly review documents or conduct special studies in connection with the proposed application, including but not limited to the reasonable costs incurred by the Planning Board for private consultation fees, fees for technical and engineering services, legal fees, or other expenses in connection with the review of a site plan application. All reasonable fees shall be charged to the applicant. The Planning Board shall make a reasonable estimate of the amount of expenses that it expects to incur during the course of each application for a site plan. The amount so determined by the Planning Board shall be deposited by the applicant in escrow with the Village Clerk prior to the Planning Board's commencing any review of the application. If the amount so deposited is exhausted or diminished to the point that the Planning Board determines that the remaining amount will not be sufficient to complete the review of the application, then the Planning Board shall notify the applicant of the additional amount that must be deposited with the Village Clerk. If the applicant fails to replenish the escrow account or there are unpaid amounts for which the applicant is responsible, the Planning Board, in its discretion, may cease review of the application until such amounts are paid or deny the application. In no event, however, shall any site plan be approved until such sums have been paid in full.
