A minimum sloping grade sufficient for drainage to the sidewalk elevation shall be established for front yards by the Chief Inspector. In instances where there are existing structures on adjoining lots the Chief Inspector shall be guided by the existing grades on the adjoining developed properties to achieve a reasonably uniform transition grade between the lots involved. All rear yards shall be graded so as to provide a gradual sloping grade from the rear wall of the building to the rear lot line. The grade at the rear lot line may be established by the Chief Inspector.
