The final step in the construction process is to restore the right of way and easement land as closely as possible to its original condition.
Depending on the requirements of the project, this process typically involves such things as replacing topsoil, removing large rocks that may have been brought to the surface, completing any final repairs to irrigation systems or drain tiles, spreading lime or fertilizer. The restoration crew carefully grades the right of way. In hilly areas, the crew installs erosion prevention measures such as interceptor dikes, which are small earthen mounds constructed across the right of way to divert water. The restoration crew also installs riprap, consisting of stones or timbers, along streams and wetlands to stabilize soils. As a final measure, the crew may plant seeds and mulch the construction right of way, to ensure the foliage and grassland is restored as close as possible to its original condition.
