TagRegional Commission On Airport Affairs(43)

Between October and December 2005, Port of Seattle contractors committed eight water-quality violations at Sea-Tac Airport's third-runway construction site, discharging muddy and contaminated water into local waterways including Lake Reba, Miller Creek, and Walker Creek. The violations resulted in $101,000 in fines levied by the Washington Department of Ecology, which also questioned whether fines alone were sufficient to prevent future incidents. The Regional Commission on Airport Affairs (RCAA) called for cooperative action between Sea-Tac Airport and the Department of Ecology to prevent further environmental damage to local streams and wetlands.

This 2005 map from the Washington State Department of Transportation's Aviation Division shows the locations and ownership types of airports across Washington State. Airports are categorized by ownership as City/County, City, County, Port, Private, or State. While centered on statewide aviation infrastructure, the map provides context for understanding the public and private entities responsible for airport operations in the region, including major facilities near the Seattle-Tacoma area.

In 2005, Washington State authorized a long-term statewide air transportation study under ESSB 5121 to assess existing airport facilities, forecast aviation demand over 25 years, and identify capacity needs for both commercial and general aviation airports. The study required formation of a governor-appointed aviation planning council to recommend how best to meet future airport needs, with a particular focus on the Puget Sound region and other high-growth areas. It also evaluated high-speed transportation options, such as rail and magnetic levitation systems, to connect airports and major population centers more efficiently.

A December 2004 newsletter from the Regional Commission on Airport Affairs (RCAA) covers three key issues: the Puget Sound Regional Council's pledge to support state legislation planning for a second major regional airport, including high-speed rail connections; widespread weight and safety violations by fill-haul trucks serving the Sea-Tac third runway construction project; and the collapse of five-year talks between state, local, and federal agencies aimed at voluntarily reducing jet engine air pollution, including smog-forming NOx emissions and hazardous fine particulate soot.

A 2004 newsletter from the Regional Commission on Airport Affairs (RCAA) reports that community opposition to Sea-Tac Airport's proposed third runway remained strong even after city-funded legal challenges were dropped due to budget shortfalls. The project, whose cost estimates had ballooned from an original $229 million to $1.3 billion, faced a $700 million funding gap, with neither tenant airlines nor the FAA willing to cover their usual shares. Critics argued the runway was being built in the wrong place—over wetlands and salmon-bearing streams—driving up costs and causing significant environmental harm.

This July 2004 newsletter from the Regional Commission on Airport Affairs (RCAA) covers legal and financial challenges surrounding the proposed third runway at Sea-Tac Airport. The Airport Communities Coalition (ACC) filed an appeal arguing that Washington State's Department of Ecology violated a State Supreme Court ruling by allowing contaminated fill materials to be used in runway construction. The newsletter also highlights that the Port of Seattle lacked a concrete financing plan for the project, with construction costs of $192.6 million already exceeding the Port's entire cash reserve.

The Washington Supreme Court reviewed a legal dispute over the environmental certification required to build a third runway at Seattle-Tacoma International Airport (SeaTac), which involved filling approximately 50 wetlands with over 20 million cubic yards of material. The case centered on whether the Washington State Department of Ecology's water quality certification provided adequate assurance that the project would not violate state water quality standards under the federal Clean Water Act. The court ultimately upheld the certification while affirming some, but not all, of the additional conditions imposed by the Pollution Control Hearings Board.

This April 2004 newsletter from the Regional Commission on Airport Affairs (RCAA) covers several developments surrounding Sea-Tac Airport, including a controversy over the Port of Seattle's plan to use contaminated fill material in the third-runway construction project in defiance of a Pollution Control Hearings Board ruling. Additional stories report on citizen groups challenging Sea-Tac's water-pollution permit, the shelving of the $3 billion North Terminal project, and a temporary McChord AFB closure that could redirect flights to Boeing Field. The newsletter reflects ongoing legal and environmental disputes between airport opponents, the Port of Seattle, and state agencies over the third-runway expansion.

This King County Water and Land Resources Division map document depicts the Walker Creek Basin, a watershed area located near Sea-Tac Airport encompassing portions of the incorporated cities of Burien, Normandy Park, SeaTac, and Des Moines in Washington State. The map identifies key waterways including Walker Creek, Miller Creek, and Des Moines Creek, along with wetlands, lakes, and river mile markers within the basin boundary. Created in 2003, it serves as a geographic reference for water resource and land use planning in this urbanized watershed area.

This King County map document depicts the Miller Creek Basin, covering portions of the incorporated cities of Burien, Normandy Park, and SeaTac, as well as surrounding unincorporated areas. It highlights key waterways including Miller Creek, Walker Creek, and the Duwamish River, along with lakes, wetlands, and notable drainage features such as the Hermes Depression and SW 142nd Street Depression. The map was produced by the King County Water and Land Resources Division and includes river mile markers and jurisdictional boundaries relevant to watershed and land-use planning in the vicinity of Seattle-Tacoma International Airport.
