What is the minimum compacted soil around a communication line?

The minimum compacted soil around a communication line is specified as 12 inches to ensure adequate protection and support for the line. This requirement helps to prevent undulations, surface subsidence, or potential damage to the line from external forces such as soil movement or settling.

Having at least 12 inches of compacted soil ensures that there is enough coverage to shield the line from environmental factors, such as moisture and varying load pressures, maintaining its integrity and functionality over time. This standard is generally based on engineering practices to promote safety, durability, and longevity of communication infrastructure.

Choosing a lesser depth does not provide sufficient protective coverage, which may lead to issues with the line's operation or even physical damage under certain conditions. The 12-inch minimum thus strikes an appropriate balance between safety and practicality in construction and infrastructure maintenance.
