The Site Grading Plan specifies the details that will be shown on the planned surface after construction. The representation of what the planned ground is expected to look like after construction, as referenced in a land development plan, is typically built by a civil engineer.
Rough grading emphasizes the initial shaping and contouring of the terrain. It establishes the primary slope, drainage, and overall layout less precisely. Rough grading provides a foundation for further work, such as landscaping and construction.
A rough grading plan is required when land disturbance will exceed 2,500 square feet and the proposed clearing and grading will not be depicted on a site plan, subdivision plan, infill lot grading plan or conservation plan.
