Do I need a grading permit, and if so, what is required to get one? A grading permit may be required if you are moving more than 50 cubic yards of earth (30’x12’x2′ area for example). A grading permit may also be required by the flood department. All grading permits require a site plan showing existing and proposed contour lines at 2ft increments as well as cut and fill amounts and finished floor or pad elevations. Where required by the flood department or when moving over 2000 cubic yards of earth, a grading permit prepared and sealed by a civil engineer registered in Arizona is required. Please refer to the Yavapai County Grading Ordinance 2014-9.
