Just a guess: maybe to keep 6 feet weeds away?

A GA. No drainage permit needed if you don't pave, at least most places.

Gravel has many qualities which make it a preferred material for layering surfaces inside substations. Its high resistivity helps ensure that the step and touch potentials remain within limits.

It also prevents growth of weeds and small plants. It mitigates the chances of a fire in the event of oil spillage. It can be easily excavated. Besides, it also prevents the entry and movement of small animals and reptiles inside the substation.

Gravel also prevents the accumulation of water and the formation of puddles inside the substation.

All these features ensure that gravel is the material of choice for use in substations.
