Estes-to-Flatiron Transmission Lines Rebuild Project

Western Area Power Administration proposes to rebuild approximately 32 miles of double wood-pole structure 115-kilovolt transmission line that exists between Estes Park and Flatiron Reservoir in Larimer County, Colo. The proposal would remove 16 miles of transmission line, and modernize 16 miles to steel-pole double-circuit 115-kV transmission line. The reduction and modernizing of transmission lines will occur on Federal, state and private lands. The public parcels are administered by the Arapaho and Roosevelt National Forest, which is a cooperating agency in the project.

The proposed project would:

  • Rebuild aging and deteriorating transmission lines
  • Reduce the number of linear miles of transmission corridors and the associated environmental footprint
  • Ensure that the transmission lines comply with applicable codes and requirements
  • Reduce potential for disruption of customer service due to wildfire hazards
  • Improve access for maintenance and emergencies

Open house, public hearing for Draft EIS - Oct. 29 and 30, 2014
Western, in cooperation with the U.S. Forest Service, held an open house and public hearing at two locations on both October 29 and 30, 2014. During the open house the public was invited to ask questions on the findings of the Draft EIS and provide comments. The comment period on the Draft EIS closed November 14, 2014. The Final EIS will incorporate comments received on the Draft EIS.
