    Airport Capital Spending (2025 $)

    A line graph showing CPI-adjusted airport capital spending in millions of 2025 dollars from 1998 through 2030 (with years 2025–2030 as forecasts), alongside a flat orange reference line representing average real spending from 1998–2024 at approximately $470 million. Spending peaked around 2002–2005 near $800 million, dropped to a low near $125 million in 2012, recovered to approximately $750 million by 2018–2019, and is forecast to peak near $975 million around 2027 before declining.

    AAA Basics of Grant Assurances

    This presentation from the 41st Annual AAAE Airport Law Workshop covers the basics of Grant Assurances — the federal obligations airports must fulfill in exchange for receiving federal funding under the Airport Improvement Program (AIP). Grant Assurances are prescribed by federal statute (49 U.S.C. 47106 & 47107) and are incorporated into grant agreements, which include both general and special conditions. While not laws themselves, these assurances are binding contractual commitments that airport sponsors accept when they receive AIP funding.

    Three votes. Three dollars.

    Funding Port Package updates made simple There’s always been confusion about Port Packages (sound insulation): Who pays for it? Who can pay for it? Who is eligible? Who should be eligible? There are a bunch of rules governing all of the above. They may seem complicated. Because they are. But the actual solutions are simple.

    Opposition to proposed revisions in FAA grant program, removing Environmental Justice, Climate, and Leaded fuel requirements

    Re https://www.regulations.gov/docket/FAA-2025-0605 Our comment to https://www.regulations.gov/docket/FAA-2025-0605 on the negative impacts new FAA regulations will have on Sea-Tac and KCIA airport communities. Although the new regulations are confined to the AIP grant program, because they are being implemented via Executive Order, it is likely that similar features will be tacked onto all FAA programs concerning leaded

    Letter from San Francisco International Airport to FAA re: Proposed Modifications to Airport Improvement Program Grant Assurances (Docket FAA 2025-0605)

    San Francisco International Airport (SFO) submitted formal comments to the FAA on May 9, 2025, opposing proposed changes to Airport Improvement Program (AIP) Grant Assurances, arguing the modifications lack legal clarity and were being rushed into effect mid-fiscal year. SFO raised concerns that incorporating certain presidential Executive Orders into grant conditions is legally problematic, as those orders are directed at federal agencies rather than state or local governments. The airport requested a 30-day comment period extension and asked that any new requirements not take effect before the start of fiscal year 2026.

    Airport Improvement Program (AIP) grant assurances

    The FAA has proposed updates to its Airport Improvement Program (AIP) grant assurances to reflect new requirements from the FAA Reauthorization Act of 2024 and recent executive orders. Key changes include removing older equity- and climate-related executive orders, adding new ones focused on free speech and ending DEI programs, and introducing a new assurance requiring airports to continue offering leaded aviation fuel (100LL) until a safe unleaded replacement is widely available. Public comments on these changes were accepted through May 9, 2025.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
