Any grading permit issued under the provisions of this article shall be valid for a period of six months from and after the date of the permit.  If the grading of the site has not been completed within six months from the date of the permit, the permit may be renewed for an additional period of six months without assessment of any fee therefor.  If any grading is not started and the work not actually begun within six months after the date of the original permit, no renewal permit will be granted, but a new application as any other permit.  The additional fee shall be on the same schedule as any other permit.
