Post-construction: The land restoration process

What happens after a project is placed into service?

After construction of energy infrastructure—including a new pipeline, or maintenance on an existing pipeline—the process of returning property to its former and agreed-upon condition begins. This process is known as restoration in the United States, and reclamation in Canada.

The process starts as soon as weather conditions and road restrictions allow. Enbridge uses approved construction and land restoration techniques. Prior to construction activities, Enbridge representatives must obtain a number of regulatory approvals and environmental permits. Those permits often prescribe practices and restoration expectations.

Working with landowners

Enbridge also meets with landowners to reach agreement on property-specific items that will be addressed during and after construction. Items on the “line list” may include:

  • repairing fences, driveways or landscaping;
  • stacking timber;
  • special care to be taken when working around livestock.

Enbridge is responsible to landowners for damages or impacts resulting from construction of expansion facilities, pipeline replacement projects or ongoing pipeline operations, all as described in our easements. We have plans and procedures to protect land before, during, and after construction.

Restoration and the environment

After construction, our goal is to restore the pipeline right-of-way to as close to pre-construction condition as possible, and minimize our long-term impact to the land along our pipelines.

Our practice of segregating topsoil during construction enhances restoration by returning the nutrients and seed back to the ground surface after construction. We also mulch, seed, and monitor the right-of-way until vegetation is re-established. In some cases, we work with landowners and environmental agencies to enhance restoration, such as planting trees along streams or managing invasive species.

Although most temporary workspaces will be allowed to grow back, we will generally maintain the permanent right-of-way free of structures, trees and shrubs so that the pipeline is visible during aerial inspections and accessible in the case of an emergency.

Landowner contacts

Enbridge has numerous pipeline projects that have recently entered service. We welcome inquiries from landowners near those projects looking for more information:

  • Edmonton-to-Hardisty Pipeline Project (Alberta): Call 1-877-767-2339 or e-mail
  • Woodland Pipeline Extension (Alberta): Call 1-780-762-4778 if north of Abee/Elk Point; call 1-877-449-2689 or 1-780-400-5664 if south of Abee/Elk Point
  • Hangingstone Pipeline Project (Alberta): Call 1-888-263-3654 or e-mail
  • Line 2 Replacement Program (Alberta): Call 1-877-449-2689 or 1-780-400-5664

Developing and maintaining good relationships with our landowners, tenants and neighbors along our energy infrastructure network is important to us. Enbridge aims to manage our existing operations and new facilities with respect for our neighbors and their land.

If you're an Enbridge neighbor with a question or a concern, please visit our contacts page to find the Enbridge land representative in your area. Alternatively, our neighbors in the U.S. can call 855-869-8261 or email One of our right-of-way agents will gladly respond to your inquiry as quickly as possible.

The restoration process, step by step

We take numerous measures to minimize our long-term impact along our pipeline rights-of-way:

  • Crews begin by removing leftover pipe, equipment and construction debris, and de-compacting soil in farm fields while restoring rough grade;
  • Next, crews pull separated topsoil back, seed, mulch, repair fences, and remove mats, bridges and access points;
  • Each restoration crew generally advances an average of three quarters of a mile (about 4,000 feet) a day, depending on land type and usage;
  • Environmental and utility crews will also be mobilized to respond to subsidence and/or drainage issues that create access problems for farmers or landowners, public safety issues, or environmental compliance issues;
  • Most restoration occurs within the first year following completion of construction. However, the process can take longer, depending on weather and other environmental impacts that may interrupt the restoration process. The initial phase involves a more visible presence of workers; crew sizes diminish as the work proceeds to completion.
