Final answer:
States have a 'call before you dig' center to prevent damage to underground utilities during excavations, ensuring safety and avoiding service disruptions.
Step-by-step explanation:
Most states have a call before you dig center to notify the utilities of your planned excavation. This is a necessary step to ensure safety and avoid damaging underground infrastructure such as gas, water, and electrical lines. By contacting the call center, they will assist in marking out all the utilities' lines that are located in the area where digging will occur. This process helps prevent possible service interruptions, injuries, and costly repairs due to accidental line damage.
