What limitation is placed on the opening of trenches for underground utility installations?

The limitation placed on the opening of trenches for underground utility installations is set to ensure safety and minimize disturbance to the site while allowing for effective management of the project. Keeping the length of open trenches to no more than 500 linear feet at any time helps mitigate risks associated with cave-ins, protects existing utilities, and minimizes the likelihood of erosion and sediment runoff that could occur with larger, uncontrolled areas of disturbance. This regulation promotes the safe and efficient completion of underground utility work while aligning with best practices in erosion and sediment control.

Additionally, setting a specific limit like 500 linear feet aids in better project monitoring and management, ensuring that any opened trench can be backfilled in a timely manner to reduce environmental impact and maintain site safety.
