    City of Normandy Park letter to Port Of Seattle re: DEIS – Sea-Tac International Airport Hotel

    In April 1995, the City of Normandy Park submitted formal comments to the Port of Seattle opposing the proposed Sea-Tac International Airport Hotel, raising concerns that the project would increase traffic congestion and reduce parking availability for local, tax-paying air travelers. The city criticized the Draft Environmental Impact Statement (DEIS) for proposing only 15 new parking spaces to serve a 16-story, 384-room hotel that could generate demand for up to 323 garage spaces at peak periods. The city recommended either no action or a smaller-scale hotel alternative that would fully accommodate its own parking needs without negatively impacting existing airport users.

    Sea-Tac International Airport Hotel draft environmental impact statement

    This March 1995 Draft Environmental Impact Statement, prepared by Kato & Warren, Inc. for the Port of Seattle, evaluates the proposed construction of a 16-story, 384-room hotel on a 77,000-square-foot site at Sea-Tac International Airport, located between the 'D' Concourse and the airport entry drives. The hotel, which would include 10,000 square feet of meeting rooms plus a restaurant and lounge, was to be connected to the terminal and parking garage via pedestrian skybridges on land then occupied by a United Airlines office building. The document was issued for public comment under Washington State's Environmental Policy Act (SEPA), with responses due by April 20, 1995.

    House Bill 1293: Soundproofing programs in aircraft noise-impacted areas

    Washington House Bill 1293 (1995) amended state law governing how port districts can address aircraft noise impacts on nearby properties, expanding soundproofing programs and removing a prior requirement that property owners waive damages and convey easements in exchange for noise mitigation. The bill declared such damage-waiver agreements void as against public policy, meaning residents near airports like Sea-Tac could receive soundproofing benefits without giving up their legal rights. The act was designated an emergency measure, intended to take effect immediately upon passage.

    Technical Report No. 6: Airside Options Evaluation — Airport Master Plan Update for Seattle-Tacoma International Airport

    This 1994 technical report, prepared by P&D Aviation for the Port of Seattle, evaluates airside development options for Seattle-Tacoma International Airport as part of a broader Airport Master Plan Update. It examines potential improvements to the existing airfield, analyzes options for adding a third runway, and assesses the operational, cost, and environmental implications of each scenario. The findings cover runway length requirements, projected airfield delays, estimated construction costs, and preliminary environmental screening results.

    Avigation Easement: Robert P. Dobosh and Shelly Arebalo-Dobosh to Port Of Seattle

    This Avigation Easement, granted by property owners Robert P. Dobosh and Shelly Arebalo-Dobosh to the Port of Seattle, gives the Port permanent, non-exclusive rights to unrestricted aircraft flight over their residential property at 15049 32nd Place S in SeaTac, Washington. The easement was granted in exchange for the Port's noise-reduction modifications to the home under Washington State law (R.C.W. 53.54.030), and establishes a baseline noise level of 67 DNL for the parcel based on the Port's 1991 FAA-accepted noise contour map. The easement runs permanently with the land, binding all future owners and waiving their rights to claim damages from aircraft noise or related airport activities.

    EXH AR026741: NPDES Permit No. WA-002465-I STIA Response to Comments

    This 1994 document is a Response to Comments on a proposed National Pollutant Discharge Elimination System (NPDES) wastewater discharge permit issued to the Port of Seattle for Sea-Tac International Airport. It summarizes public feedback gathered at meetings in Des Moines and Normandy Park, Washington, addressing topics such as storm water management, effluent limitations, spill plans, and pollution prevention at the airport. The document reflects the Department of Ecology's review of industrial wastewater, cooling water, and storm water discharges from airport operations including aircraft maintenance, fueling, and de-icing activities.

    Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments

    This document presents the Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments, submitted by the Port of Seattle and approved by the Federal Aviation Administration on May 18, 1994. It outlines updates to existing noise-reduction measures—including sound insulation for homes and public buildings, a transaction assistance program, and an expanded noise monitoring system—as well as newly recommended measures such as community planning forums and operational reviews. The program aims to reduce noncompatible land uses around Sea-Tac Airport and prevent the introduction of new ones.

    This document presents the Seattle-Tacoma International Airport FAR Part 150 Noise Compatibility Program: 1993 Amendments, submitted by the Port of Seattle and approved by the Federal Aviation Administration on May 18, 1994. It outlines a series of noise mitigation measures—including sound insulation programs for homes and public buildings, a transaction assistance program for affected property owners, and an expanded noise monitoring system—aimed at reducing noncompatible land uses around Sea-Tac Airport. Three new measures were also recommended, covering funding for land use planning, a community planners forum, and ongoing operations review and noise exposure map updates.

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.
