Pre-construction activities
These activities allow the project team to verify information about the route to help minimize impacts for structure locations and construction of the transmission line. View our field surveys handout to learn more about these activities.
- Right-of-way and structure staking
- Wetland and stream surveys
- Wildlife surveys
- Noxious weed surveys
- Soil borings
- Cultural resource surveys
Construction activities
- 1 Initial surveying, right-of-way clearing and access routes
- 2 Structure staking, surveying and soils investigations as needed
- 3 Foundation installation Foundation type may vary depending on structure
- 4 Assemble and set structures
-
5
Wire installation
- 6 Cleanup and restoration Helicopters may be used to assemble and set structures and wire installation
Construction impacts
We will do our best to minimize impacts during construction; however, the following temporary impacts will occur:
- Construction area staking
- Noise, dust and lights for nearby residents
- Equipment (such as pick-up trucks, tree-clearing machines, anchor-drilling trucks and wire-stringing vehicles), materials and construction crews located along the road and in project right-of-way
- Work during daytime hours with potential for some work to be completed outside normal working hours (7 a.m. - 7 p.m.)
- Temporary lane and road closures
- Signage and traffic management
- Removal of all trees and other tall vegetation within the easement area
- Erosion control measures will be taken to reduce impacts to streams and wetland areas
- Mat installation to minimize surface disturbance
Restoration and maintenance
A project representative will assess damages incurred during construction and contact each property owner to settle claims for any such damages. After construction is complete, damaged property will be restored as close as possible to its original condition. Landowners will be fairly reimbursed if damage occurred to crops, fences or other property during construction.
Following construction, Minnesota Power and Great River Energy will conduct ongoing maintenance of the transmission line, including but not limited to line inspections, surveys and vegetation management.
