Application for permit shall be made to the Division and shall describe specifically the location, nature and extent of the proposed work, the purposes thereof, and the right, if any, of the applicant to do such work. The application shall be accompanied by a plat, in duplicate, showing the location of each proposed excavation, the dimensions thereof, and such other details as the Division may require. Where, in the opinion of the City Engineer, the work to be done is of a minor nature, the requirement for duplicate plats may be waived and a sketch on the application form shall be submitted in lieu thereof. Applications for annual blanket permits need not be accompanied by a plat or sketch. If the applicant is lawfully entitled to do such work, or any portion thereof, at the place and in the manner proposed, the Division shall issue a permit for the doing of such work, or any portion thereof, as the case may be; provided, however, that no permit shall be issued by the Division until the applicant has paid the prescribed fee and deposited security for completion of the work as hereinafter provided.
