​Land management near pipelines and power lines


Right-of-way is a strip of land where some of the property owner's legal rights have been granted to a utility company. The right-of-way enables a utility company to operate, inspect, repair, maintain or replace a pipeline on property owned by others.


Anything that is placed into a right-of-way contrary to the terms of the easement is called an encroachment.
