What is the maximum burial depth requirement under a commercial driveway?

The maximum burial depth requirement under a commercial driveway is specified at 24 inches. This depth is determined by regulations to ensure the safety and integrity of gas piping systems as they are subjected to potential physical stress from vehicles and heavy traffic common in commercial settings. Burial at this depth helps prevent damage due to ground movement, frost penetration, or accidental digging by maintenance activities.

Choosing a burial depth that is too shallow could expose gas lines to increased risks, such as rupture or leaks, which could compromise safety. Conversely, a deeper burial could lead to unnecessary excavation and difficulty in access for future repairs or adjustments. Hence, the requirement for 24 inches strikes an appropriate balance between safety and practicality in managing gas pipelines beneath thoroughfares like driveways.
