A. 
The Township Engineer shall, when requested, make the inspections hereinafter required and shall either approve that portion of the work which has been completed or notify the permit holder wherein the same fails to comply with the provisions of this chapter. Where it is found by inspection that the soil or other conditions are not as stated or shown in the application, the Township Engineer may refuse to approve further work until approval is obtained for a revised grading plan conforming to existing conditions.
B. 
Plans for grading work, bearing the stamp of approval of the Township Engineer, shall be maintained at the site during the progress of the grading work and until the work has been approved.
C. 
The permit holder shall notify the Township Engineer in order to obtain inspections in accordance with the following schedule and at least 24 hours before the inspection is to be made:
(1) 
Initial inspection: when work on the excavation or fill is about to be commenced.
(2) 
Rough grading: when all rough grading has been completed.
(3) 
Drainage facilities: when drainage facilities are to be installed and before such facilities are backfilled.
(4) 
Special structures: when excavations are complete for retaining and crib walls and when reinforcing steel is in place and before concrete is poured.
(5) 
Final inspection: when all work, including the installation of all drainage and other structures, has been completed.
D. 
If, at any stage of the work, the Township Engineer shall determine by inspection that the nature of the formation is such that further work as authorized by an existing permit is likely to endanger property or streets or alleys or create hazardous conditions, the Township Engineer may require, as a condition to allowing the work to be done, that such reasonable safety precautions be taken as the Township Engineer considers advisable to avoid such likelihood of danger. Safety precautions may include, but shall not be limited to, specifying a flatter exposed slope, construction of additional drainage facilities, berms, terracing, compaction or cribbing.
A. 
If, upon final inspection of a grading, excavation or fill, it is found that the work authorized by the permit has been satisfactorily completed in accordance with the requirements of this chapter and any other requirements imposed, a grading certificate covering such work and stating that the work is approved shall be issued to the permit holder by the Township Engineer.
B. 
The Township Engineer shall have the power to revoke any grading certificate whenever he finds that the work covered by the certificate has been materially extended or altered without a permit so to do, or that any retaining wall, cribbing, drainage structure, fence or other protective device shown on the approved plans and specifications submitted with the application for a permit have not been maintained in good order and repair.
C. 
Before such revocation, the Township Engineer shall first give written notice to the permit holder and to the owner of the property involved, specifying the defective condition and stating that unless such defective condition is remedied satisfactorily, the grading certificate may be revoked. If the defective condition is remedied, the certificate shall not be revoked.
