Apply for airport grants

WSDOT's Airport Aid Grant Program focuses on preservation of airports. Airports are vital to Washington State, fueling its economy and providing critical links to the state and national transportation system.

Airports are vital to Washington State, fueling its economy and providing critical links to the state and national transportation system. WSDOT Aviation has been charged with the general supervision over the Airport Aid Grant Program pursuant to RCW 47.68 on the legislature website in which the program provides crucial financial assistance to public-use airports in the preservation of Washington's system of airports.

Who can apply

Under RCW 47.68.090 on the legislature website, any city, county, airport authority, political subdivision, federally recognized Indian tribe, public corporation, or person(s) that owns and operates, a public-use airport included in the Washington Aviation System Plan (WASP) is considered an eligible airport sponsor and may apply for WSDOT Airport Aid grant funds. The municipality, tribe, or person(s) may act jointly with other municipalities, tribes, or persons to plan or carry out the project.

The airport sponsor must own or, in some cases, have a long-term lease (minimum twenty years) for the land upon which the project will be accomplished. Airports should continue their CIP planning throughout the year to prepare for the next SCIP submission window from Sept. 1 - Oct. 31 for the grant cycle that begins in July 2021.

Projects must be included in WSDOT's State Capital Improvement Program (SCIP).

Sponsors should provide information that will help WSDOT develop an informational Web page about the project:

  • Why is WSDOT Aviation investing in this project?
  • What will the end result be?
  • What are the benefits of this project? (i.e. will it improve safety or security, benefit the environment, change operations, etc.)
  • What is the project timeline?
  • What public outreach or involvement will be done as part of this project?
  • What will be done to protect the environment? See the environment design topic for more information.
  • Will this project impact tribal resources?
  • Number of jobs the project is expected to create
  • Financial details, including a funding breakdown (i.e. What portion of funding is FAA/State/Local/Other)
  • Who can the public contact for more information?

Maximum grant

The maximum amount WSDOT Aviation can award to an individual sponsor in a single grant is $750,000.

Airport sponsor local match requirement

On projects seeking state funds only, the airport sponsor must contribute a minimum 5% match of the entire project cost. If the sponsor is able, and would like to contribute a larger match amount, they certainly can and will receive additional points towards their total project application score during WSDOT Aviation's prioritization review of all grant applications.

For projects receiving federal funds, it has been a long-standing practice of the Airport Aid Program to support airports in matching their Airport Improvement Program (AIP) grants. Currently, AIP grants require 10% of the project total to come from the airport sponsor. WSDOT supports grants to airports for up to half of their match requirement.

Eligible project types

The intent of the WSDOT Airport Aid Program is to provide sponsors of public-use airports with funds to preserve our state system of airports. Airports are critical links to the state transportation network and it is the role of the grant program to fund projects that strengthen Washington's aviation infrastructure.

WSDOT Airport Aid grant funds may be used for the planning, acquisition, construction, improvement, and maintenance of airports. All project work must be available for public use and be shown on the approved Airport Layout Plan (ALP). All projects must be included in WSDOT Aviation's five-year Statewide Capital Improvement Program (SCIP).

Grant award timeline

WSDOT solicits grant applications and awards funds once each year. During odd-numbered years (e.g. 2017, 2019, etc.), the grant schedule is constrained by the state's biennium, which prohibits grant awards prior to July 1. Thus, during odd-numbered years WSDOT typically solicits applications from airport sponsors between March and May and announces grant awards by July 15.

During even-numbered years (e.g. 2018, 2020, etc.), the grant solicitation and award schedule is earlier to better align with the typical construction season. Thus, during even-numbered years applications are solicited between February and March with grant awards announced by May 15.

Airport sponsors can elect to submit a grant application at any given time during the year (outside of the official solicitation) to be considered for the next grant cycle.

Airport Information System Database

As a condition for grant eligibility, airport sponsors are required to update their information annually on the Airport Information System database. Airport sponsors must first log into the system in order to view and update information. Airports can request their User ID by emailing with the following information:

Sponsor name, address, phone number, and email.
