II. Grading/Site Plan 1. General requirements- A grading plan is required fr all prjects invlving any significant changes f grade. The grading plan shwing must shw existing and prpsed grund cnturs and elevatins fr cut and fill peratins, and all pertinent infrmatin related t grading and infrastructure.
