A construction activity is part of a larger common plan of development if it is completed in one or more of the following ways:
- In separate stages
- In separate phases
- In combination with other construction activities
It is identified by the documentation that identifies the scope of the project including such things as the following:
- Building permits
- Marketing plans
- Public notice or hearing
- Zoning requests
It can include one operator or many operators.
Example: A subdivision is being built. You are grading 0.75 acres, another company is clearing 4 different acres and a contractor is excavating another 0.5 acres. In this case, the total area that would be disturbed is 5.25 acres, so each operator would fall under the requirements associated with disturbing 5 or more acres.
