Anchorage Runway 7R Extension Environmental Assessment
The Alaska Department of Transportation and Public Facilities expanded Runway 7R to reduce aircraft delays and increase airfield capacity at Ted Stevens Anchorage International Airport. The project increased the landing length between the Runway 7 threshold and the planned high-speed taxiway exit at Taxiway G by moving the Runway 7 threshold to the west. A second project, Runway 7R/25 Reconstruction, upgraded the runway surface. This effort extended Runway 7R by 1,500 feet and brought it up to Airplane Design Group VI standards.
HDR completed an Environmental Assessment (EA) for the Runway 7R Extension project. We also provided permitting, public involvement and related services for both the Runway 7R Extension and Runway 7R/25 Reconstruction projects.
Our scope of work included documenting impacts of rerouting existing public use trails that were on the site by completing a visual analysis of the approach lighting system towers and the proposed trail reroute. We also evaluated critical impacts, including water quality, wetland impacts and cultural resources sections of the EA in support of the trail mitigation. Finally, we assisted the Alaska Department of Transportation and Public Facilities with collecting public comments, presenting findings at the public hearing, and coordinating with the Federal Aviation Administration to complete the EA. The successful project led to a finding of no significant impact and was constructed on schedule.
