No person shall commence or perform any grading without having first obtained a grading permit from the Engineer. A separate grading permit shall be obtained for each site. One permit may cover both an excavation and any fill made with the excavated materials on the same site. For any grading that is to be performed, or for any unprotected graded surface that is to remain, during the period of October 15 to April 15, a separate erosion control permit is required.
