There shall be a nonrefundable fee in the amount necessary to compensate the town for the expense of reviewing and processing plans, conducting inspections, providing for outside consulting services, and other services determined to be necessary for the administration and enforcement of the provisions of this chapter. Such fees shall only apply when plans or other documentation are required to be submitted with permit applications for grading and filling or clearing and drainage activity, and no building permit including such activities has been issued. The permit fee shall be paid at the time of submitting plans and other documentation for review. After approval of the plans and specifications, the town engineer shall provide the applicant with an estimate of the construction inspection fee, based upon the inspections, which will be necessary. Such inspection fee shall be separate from the above plan review fees. A permit for construction will be issued only after the deposit of the inspection fee has been made with the town treasurer. If the town engineer determines that the remaining funds on deposit are not adequate to pay for the inspections required for project completion, the applicant will be so notified and provided with an estimate of the amount of additional fee deposit required. This additional fee shall be deposited with the town treasurer prior to depletion of the funds on deposit. Any monies unexpended from the deposit shall be refunded to the depositor upon final completion and acceptance of the project. [Ord. 378 § 2 (Exh. 1), 1999.]
