At a March 1, 2012 Des Moines, WA City Council study session, staff presented a policy discussion on whether to update the city's Sound Transmission Control (Sound Code) requirements, which govern noise-reducing construction standards for buildings near Sea-Tac Airport.

The Council was asked to consider options ranging from immediate regulatory relief—such as reducing sound zones, limiting requirements to windows only, or making compliance voluntary—to waiting until the 2016 study is complete before making any changes.
