Dr. Stephen L. M. Hockaday, a Professor Emeritus of Civil and Environmental Engineering at Cal Poly San Luis Obispo with over 25 years of airport and airspace planning experience, submitted this declaration in support of the Airport Communities Coalition's emergency motion for injunctive relief before the Washington Supreme Court. The case involves the Port of Seattle, the Pollution Control Hearings Board, and the Washington Department of Ecology in a dispute related to Sea-Tac Airport expansion. Dr. Hockaday's credentials include serving as Head of Eurocontrol's airspace and airport modelling service and managing major FAA programs at the nation's ten busiest airports.

A 2002 presentation to the Washington State Senate Transportation Committee argues that regional airports play a vital role in relieving pressure on major hubs like Sea-Tac by distributing aviation demand across multiple facilities. The presentation highlights that many large metro areas already operate successful multi-airport systems—such as the New York and Los Angeles regions—and that low-cost carriers actively seek out regional airports for their cost and service advantages. It also notes that a post-9/11 drop in air travel demand created an opportunity to study and plan for expanded regional airport capacity in Washington State.

Declaration by Stephen L. M. Hockaday, Professor of Civil and Environmental Engineering at Cal Poly San Luis Obispo and expert in airport/airspace planning, filed in support of Airport Communities Coalition (ACC) Motion for Stay in PCHB Case Nos. 01-133 and 01-160. Opposes Port Of Seattle construction of Third Runway at Sea-Tac Airport pending resolution of

In 1996 congressional testimony, Dr. Stephen Hockaday argued against building a costly third runway at Seattle-Tacoma International Airport, contending that the Port of Seattle greatly overstated the frequency of poor weather conditions that would require it. He presented evidence that true instrument flight conditions occur less than 8% of the year—not the 44% the Port claimed—and that existing navigation technologies like Localizer Directional Aid approaches could address capacity needs at far lower cost. Hockaday warned that spending half a billion dollars on a runway used only 15% of the time would divert resources from better long-term regional aviation solutions.
