Grading is regulated by the Development Standards. A grading permit is necessary prior to performing most grading operations in the City of Tucson. All plans require a minimum 10pt font. The following require a grading permit unless exempted from the requirements of the grading code:
The following is exempted from the need to obtain a grading permit. Other permits (floodplain, for example) may still be required.
Exemption from the permit requirements of this chapter shall not be deemed to grant authorization for any work to be done in any manner in violation of the provisions of this chapter or any other laws or ordinances of this jurisdiction.
It should be noted that it does not take very much soil to exceed the fifty (50) cubic yard requirement. Please see the following table:
|Area (Square Feet)||Dimensions (Feet)||Height of Fill (Feet)|
|500||22 X 22||2.7|
|1000||32 X 32||1.35|
|2000||45 X 45||0.67 (8 inches)|
|5000||71 X 71||0.27 (3 inches)|
So the fill placed over a typical small residential lot generally requires a grading permit.
A bond may be required to ensure reseeding of the site should grading cease for a period of sixty (60) days. In some cases where hazardous conditions may occur, a separate bond may also be required to correct hazardous conditions resulting from an incomplete project.
Fees are required for grading plan review and issuance of permits.
For any project greater than one (1) acre, or which is part of a project greater than one (1) acre, a surface water pollution prevention plan (SWPPP, usually pronounced “swip”) is required by state regulation (AzPDES). Notices must also be sent to the Environmental Protection Agency (EPA) prior to and at the completion of grading.
If work is performed in a regulatory floodplain you must also obtain a Floodplain Use Permit. These are also available from Development Services. Native plants on the site must also be protected per applicable codes and standards.
Placement of fill in excess of two (2) feet above existing grade at any location in the outer one hundred (100) feet of a developing site requires compliance with differential grading criteria. This applies to residential lots smaller than 24,000 square feet and all non-residential developments.
All grading should have adequate drainage provisions and conform to the requirements of the Development Standards (DS 11-01.6.0).
