    DOT Regulation Appendix – Subpart B, Section 25.101(a): General Provisions on Real Property Acquisition

    This DOT regulation (Subpart B, Section 25.101a) outlines when federal property acquisition rules apply, covering situations involving eminent domain threats and large-scale planned project areas. It also defines the conditions under which an acquisition can be classified as a 'voluntary transaction,' exempt from those requirements — including that the agency must inform the owner it will not forcibly acquire the property if negotiations fail. When multiple properties are purchased voluntarily within the same area, all owners must be treated equally regarding eligibility for benefits under the Uniform Act.

    Letter to all recipients of U.S. Department of Transportation funding

    In an April 2025 letter, the U.S. Secretary of Transportation reminded all DOT funding recipients — including state and local governments — that they must comply with federal anti-discrimination laws, including prohibitions on race- and sex-based preferences, and must cooperate with federal immigration enforcement. The letter warns that programs or policies tied to 'diversity, equity, and inclusion' goals may violate federal law, and that issuing driver's licenses to undocumented individuals or otherwise impeding ICE could constitute noncompliance. Recipients who fail to meet these obligations risk losing federal transportation funding, facing audits, or having grant agreements terminated.

    Port Of Seattle Letter to Secretary Buttigieg Supporting Delta Air Lines SEA-DCA Flight Application

    In a June 2024 letter to U.S. Transportation Secretary Pete Buttigieg, Port of Seattle leaders expressed strong support for Delta Air Lines' application to add a new daily nonstop flight between Seattle-Tacoma International Airport (SEA) and Ronald Reagan Washington National Airport (DCA). The letter highlights that only two direct flights per day currently serve the SEA-DCA route, leaving most Pacific Northwest travelers bound for the Washington, D.C. area to use connecting flights or more distant airports. Port officials argue that adding the new route would increase competition, lower fares, and improve access to the nation's capital for residents throughout the Pacific Northwest.

    AAAE Response to DOT Request for Information on Advanced Air Mobility (Docket No. DOT-OST-2023-0079)

    The American Association of Airport Executives (AAAE) submitted formal comments to the U.S. Department of Transportation in August 2023 regarding the future of Advanced Air Mobility (AAM), including electric vertical takeoff and landing (eVTOL) aircraft. The letter highlights key obstacles facing airports, such as limited electrical power supply, uncertainty about commercial viability, and a lack of FAA guidance on safely integrating these new aircraft into airport facilities. It also raises concerns about new safety risks, particularly the challenges of firefighting lithium-ion battery fires from electric aircraft, urging the FAA to provide clearer emergency response protocols.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

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.
