    Airport noise mitigation program implementation guidelines

    This document outlines how airport noise impact programs can be approved and funded under the Airport Improvement Program (AIP). Once a detailed study confirms substantial community noise impact and a reasonable solution is proposed, costs become eligible for approval. Specific guidelines must then be developed covering property acquisition or sound insulation options, including owner agreements, appraisals, market exposure, noise insulation standards, and relocation proposals.

    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
