When marking a dig site on a map, draw the polygon or radius large enough to notify necessary members but not too large to notify unnecessarily. When there is an address point on the same street, draw a polygon around the address. If no address point exists, mark both sides of the road. For rural areas without clear address information, get directions and mark both sides. When information is conflicting, mark both sides as a safety precaution. Adjust markings based on available parcel and address point data, and use best judgment to clearly mark the intended area.
