12
A construction project is not part of a larger common plan of development if: The project is considered to be separate or stand alone and is not part of any other construction project or larger common plan of development or sale It is a discrete project within a common plan of development that is ¼ mile or more from the nearest site, and: All land disturbance between projects is completed (will not be further built out), andAll land disturbance between projects is completed (will not be further built out), and Not connected by roads, pipelines, or utility construction projects that are included in the area to be disturbedNot connected by roads, pipelines, or utility construction projects that are included in the area to be disturbed
13
