It shall be the duty of the Code Enforcement Officer or designee, upon the filing of the application for said permit, to examine all of the data submitted to him with the application and, if necessary, the building or premises upon which it is proposed to erect the sign or other advertising structure. If it shall appear that the proposed sign is in compliance with all of the requirements of this chapter and other rules and regulations of the Village of Manchester and has been approved as to design, size and location by the Planning Board, as provided for herein, a permit for the erection of the proposed sign shall be issued. If the sign authorized under any such permit has not been completed within six months from the date of the issuance of such permit, the permit shall become null and void, but may be renewed for one additional six-month period upon the approval by the Planning Board and upon payment of an additional fee. A request, which cites the reason for requesting the extension for the completion of the sign, shall be submitted in writing to the Planning Board not more than 30 days following the first six-month expiration period.
