 Excavation is benched for at least 2 feet horizontally for every 5 feet of depth.
 Minimum horizontal width at eh bottom of the excavation is no less than 2 feet or wider.
 No water, surface cracks, or other conditions that might reduce the stability of the excavation.
 No heavy equipment or machinery operating in the vicinity that might de-stabilize the excavation.
