In January 2010, the Port of Seattle sought approval to advertise construction bids for environmental cleanup work tied to the Seattle-Tacoma International Airport Third Runway project, including removing the 160th Street box culvert, restoring Miller Creek, and converting temporary stormwater ponds into permanent detention facilities. The estimated $6.6 million project was already funded within the previously approved Third Runway budget through Passenger Facility Charges and bond proceeds, requiring no new funding authorization. The work was required to fulfill federal and state permit conditions before the overall Third Runway project could be formally closed out.

Ordinance No. 1407 is a City of Des Moines, Washington municipal ordinance that updates and consolidates the city's Buildings and Construction Code (Title 14) by adopting the latest editions of major building, fire, mechanical, electrical, and plumbing codes, including Sound Control Requirements relevant to the Sea-Tac Airport noise environment. The ordinance repeals more than 40 previously enacted building-related ordinances dating back to 1959 and brings the city into compliance with state-mandated building standards under RCW 19.27.031. It establishes updated rules for administration, enforcement, and a range of construction-related regulations applicable within the City of Des Moines.

This appendix compiles four reference guides on the life expectancy of common home building materials and components, including studies from the National Association of Home Builders, Fannie Mae, and the International Association of Certified Home Inspectors. The materials cover expected useful lifespans ranging from 5 to 100 years for items such as roofing, flooring, and mechanical systems. These references are intended to support housing assessments and affordable housing planning decisions.

This document is a 30% design submittal prepared by HNTB Corporation for the Third Runway Embankment Construction Phase 4 project at Seattle-Tacoma International Airport. It is an oversized engineering exhibit, submitted without a date, representing an early-stage design milestone in the ongoing construction of the airport's third runway. The submittal is part of the administrative record (AR 025787) related to the runway expansion project.

This document outlines the Port of Seattle's soil fill quality criteria for the first phase of construction of a new runway embankment, involving approximately 820,000 cubic yards of material placed in 1998. It details the approved sources for fill material, technical specifications for soil gradation and contamination standards, and the certification and monitoring processes required of contractors. Independent soil technicians and Port consultants were tasked with overseeing material delivery, placement, and compliance testing throughout the project.

This document (AR 019657) is a site map of an active construction area at what appears to be Sea-Tac Airport, showing a restricted AOA (Air Operations Area) zone, embankments, and Lagoon 3. Handwritten annotations reference two stockpiles dated 1997 and 1999, with approximate volumes of 400,000 cubic yards and 2,100,000 cubic yards respectively. The map was entered as Exhibit 284 on 2/7/02, with witness Clark and court reporter Diane Mills.
