Annual Proposed Airport Improvement Program

Each year, the Illinois Department of Transportation (IDOT) develops the Annual Proposed Airport Improvement Program. It is designed to provide an overview of the airport improvement program, as well as a current listing of all airport projects programmed for the next federal fiscal year in an effort to inform the general public and aid local transportation stakeholders and business partners in specific planning activities.

For Fiscal Year 2022, the Illinois Department of Transportation’s Annual Proposed Airport Improvement Program includes projects at airports throughout the state to ensure continued safe and efficient operations at these facilities, as well as maximizing opportunities for economic development in Illinois. Justified and eligible projects are selected from the Transportation Improvement Program (TIP) submittals and evaluated based on the Federal Aviation Administration’s (FAA) National Priority Rating (NPR) and need. The FAA provides the State of Illinois the preliminary federal programming levels annually for programming purposes. The Annual Proposed Airport Improvement Program does not reflect all known airport needs and deficiencies, but primarily those that have been identified by airport sponsors, the FAA, and IDOT, and found to be consistent with IDOT’s goals.

Limited resources require an airport project evaluation system that maximizes available funds while keeping consistent with national, state, and local community needs. In order to make the best use of the limited state and federal airport development funds, the Illinois Department of Transportation (Department) follows a FAA’s National Priority Rating (NPR) system that allows the Department to identify projects that meet present system needs. Current project priorities are:

  • Safety: Projects needed to make the airport facilities safe for aircraft operations.
  • Preservation: Projects to preserve the functional or structural integrity of the airport.
  • Standards: Projects required to bring the airport up to design standards for current aircraft using the facility.
  • Upgrade: Projects required to allow the airport to accommodate larger aircraft which can carry more passengers or cargo.
  • Capacity: Expansion projects required to accommodate more aircraft at peak times.

Following these priorities, the Department is able to assist local communities in providing an environment that meets current state and/or federal safety standards, preserving the existing airport infrastructure, and encouraging economic growth by assisting airport sponsors with new development and expansion projects where a clear and demonstrated need exists.

Illinois Aviation System

The State of Illinois plays a critical role in the National Airspace System (NAS). Aviation serves as a global gateway, connecting Illinoisans to the world. The aviation industry is a major contributor to the Illinois economy, and last year alone, over 87.4 million commercial passengers flew to, or through, Illinois airports. Illinois airports saw over 2.5 million operations (takeoff or landing).

There are 77 airports in Illinois that are publicly owned, open to the public and eligible for public funding. All of these airports are owned and operated by local sponsors with the State of Illinois acting as a co-sponsor for funding purposes. These airports are eligible for federal funding and all of them, except Chicago O’Hare International (ORD) Airport and Chicago Midway International (MDW) Airport, are eligible for state airport improvement program funding.

In addition to the publicly owned airports, there are 38 privately owned airports which are open to the public, 548 restricted landing areas which are only open to people approved by the owner and 273 heliports which are used mainly by individuals, hospitals and corporations. None of these privately owned facilities are currently eligible for public funding.

Illinois’ public-use airports generate billions of dollars in total annual economic activity, resulting in hundreds of thousands of jobs that can be traced to the aviation industry. According to a recent Federal Aviation Administration (FAA) report, The Economic Impact of Civil Aviation on the U.S. Economy (2015), the total annual economic output from the Illinois aviation industry is $50.9 billion. Furthermore, the aviation industry in Illinois is responsible for over 366,000 jobs. The study also found that aviation accounts for more than 4.2 percent of Illinois’s GDP and nearly 5 percent of the State’s jobs . In addition to these economic benefits, airports in Illinois provide a number of health, welfare, and safety benefits. Services such as medical transport and evacuation, flight training, law enforcement flights, military exercises, and search-and-rescue operations all contribute directly to the quality of life of those who live and work in Illinois. Additionally, visitors who arrive on commercial airlines or on private aircraft also create economic activity through local spending at hotels, restaurants, retail stores and entertainment establishments. All of these actions contribute directly to creating additional jobs and greater local economic benefits.

Rebuild Illinois Airport Capital Improvement Program

CIP logo

Program Purpose

The Rebuild Illinois Airport Capital Improvement Program (ACIP) provides competitive grants for the planning, construction, reconstruction, extension, development, and improvement of public-use airports that are included in the Illinois Aviation System Plan (IASP). ACIP grants augment the continual Federal Airport Improvement Program (AIP), and other state aviation programs, where funding limitations and constraints prevent otherwise justified projects from being completed.

In the Spring of 2019, Rebuild Illinois appropriated the sum of $144 million to the Illinois Department of Transportation (IDOT) for such purposes, in accordance with the Illinois Aeronautics Act and other applicable state statutes. Considering demand for funding a growing backlog of justified improvements to the Illinois Aviation System (IAS), and the complexity inherent in the planning, design, letting and construction process for airports, IDOT will utilize this 6-year capital bill appropriation to establish no greater than a 4-year ACIP from FY 2021 – FY 2025.

Additionally, Rebuild Illinois appropriated the sum of $6 million to IDOT for a grant to Lewis University Airport for costs associated with erecting an air traffic control tower. This project is expected to follow the same program timeframe, although consideration must be given to Federal Aviation Administration (FAA) coordination and requirements.


$94 million is available for the Rebuild Illinois Airport Capital Improvement Program, It is anticipated funds will be programmed over state fiscal years FY 2022 – FY 2025.


Eligible applicants are public-use public-owned airports in Illinois.

Furthermore, to be eligible for a grant, an airport must be included within the IASP. This listing can be found in the resources below.

Recipients of grants are referred to as "sponsors." Sponsors must be legally, financially, and otherwise able to carry out state and federal assurances and obligations contained in the project application and grant agreement, including the ability to meet and comply with the Grant Accountability and Transparency Act (GATA).
