Welcome to the Tacoma Narrows Airport (TIW) Environmental Assessment Online Open House!
To comply with Federal Aviation Administration (FAA) design standards, Pierce County is completing an Environmental Assessment (EA) for several projects that are proposed at the Tacoma Narrows Airport over the next five years (2022 – 2026).
These projects are proposed to improvesafety at the airport and bring the runway and taxiway at Tacoma Narrows Airport in compliance with current FAA standards.
These projects do not include a runway extension, and do not affect the type or size of aircraft that currently operate at the airport.
These projects were previously identified as part of the Airport Master Plan for Tacoma Narrows Airport, which was completed by Pierce County in 2016. The County then received FAA approval and funding to proceed with the Environmental Assessment. The EA is required so that Pierce County can then apply for FAA funding for design and construction of these projects, over the next five years.
All projects that receive federal funding are required to be reviewed under the National Environmental Policy Act (NEPA) to ensure that the proposed projects consider, and when possible avoid environmental impacts. This process includes the following steps:
The Environmental Assessment (EA) is 90% funded through an Airport Improvement Program (AIP) grant from the FAA. The remaining funds are covered by Pierce County.
If the projects proceed forward, future phases of the projects (design and construction) are also anticipated to be funded by 90% FAA AIP grants for all eligible costs. The County will also be applying for matching funds through other sources, including the Washington State Department of Transportation Aviation Division.
The Airport Master Plan, completed in 2015, identified improvements needed at the airport and resulted in the project timeline (right).
This project includes the removal of trees located on airport property. These trees are located in areas that should remain clear to allow for safe operation of the type of aircraft that currently operate at the airport. Chainlink fencing is also proposed to keep wildlife from entering areas where aircraft operate.
This project includes the relocation of the parallel taxiway (Taxiway A). The parallel taxiway is currently located 350 feet from the runway; the taxiway is proposed to be shifted 50 feet to the east to meet Federal Aviation Administration (FAA) Design Standards for runway-taxiway separation. In addition, Taxiway Connector B4 is proposed to be relocated, and the Apron is proposed to be expanded, to meet FAA Design Standards.
To accommodate the Taxiway A relocation, an existing open-air stormwater facility is proposed to be converted to an underground vault.
This project includes additional removal of trees on airport property. These trees are located in areas that should remain clear to allow for safe operation of the type of aircraft that currently operate at the airport. These additional tree removals are proposed to occur over the next five years, as funding becomes available. Trees that have the greatest potential impact on safety will be prioritized for removal (these are generally the tallest trees located the closest to the runway ends).
Requires stormwater pond to be filled to accommodate taxiway relocation
Temporary roads to access tree removal areas
Temporary disturbance to streaked horned larks and other wildlife during construction
Removal of streaked horned lark habitat
Loss of forested habitat
Supports local/regional transportation system and economy
