The City of Renton has transitioned into recovery from the December 2025 atmospheric river event. For recovery resources, please visit our website.
Taxiway Alpha is the major parallel taxiway that supports all GA aircraft operations and Boeing 737s towed between the B ramp and C ramp on the west side of the field.
The existing pavement is showing stress, cracking, and rutting. This project includes a major reconstruction of the entirety of the taxiway and will include an LED lighting upgrade, infield drainage improvements, and painting.
We anticipate the contractor to begin mobilizing their equipment and materials as early as February into the designated staging areas.
Special consideration will be made to tenants who will be affected by the work area directly between their operation and the closed taxiway. 800 and 820 aprons will be made available to tenants impacted by this project.

This is the second phase of the 2013-2014 Seaplane Base Dredging & Shoreline Mitigation project. It will add rip-rap along the runway end edge adjacent to the seaplane launch ramp to prevent continued erosion of the shoreline.
