Which organization should be contacted to ensure proper location of utility services before excavation?

The organization that should be contacted to ensure proper location of utility services before excavation is MISS DIG. This is a key service in Michigan that helps prevent accidents and service interruptions by marking the locations of underground utility lines. By calling MISS DIG, contractors and individuals excavating can request accurate information about where utilities, such as water, gas, electricity, and telecommunications, are buried. This action is essential for safety and compliance with state regulations, which mandate that utility lines be marked before any digging occurs.

Local utility providers are involved in the process as well, as they may provide information about their specific lines, but MISS DIG serves as the centralized service for this purpose across various utilities, ensuring a comprehensive approach. The city planning department and local contractors association do not typically have the resources or functions specifically designed for marking underground utilities, making them less relevant in this context. Thus, contacting MISS DIG is the most direct and efficient way to ensure safe excavation practices.
