Grading

Land grading is reshaping the ground surface to planned grades as determined by engineering survey evaluation and layout. Grading of lots within a subdivision ensures that the runoff from each one is directed to a stable outlet rather than to an adjacent lot.

The purpose of grading is to provide more suitable topography for buildings, facilities and other land users; to control surface runoff; and to minimize soil erosion and sedimentation both during and after construction. The plan should define areas that must not be disrupted by grading and filling, including staking, marking and fencing required to prevent damage to these areas. These practices are applicable where grading to a planned elevation is necessary and practical for the proposed development of a site and for proper operation of sedimentation-control practices.
