SUBJECT:  2017 Airport Economic Impacts Study Briefing 
EXECUTIVE SUMMARY 
The purpose of this briefing is to discuss with the Commission the results of the 2017 Airport
Economic Impacts Study. 
BACKGROUND 
The 2017 Airport Economic Impacts study measures the economic impacts of the Airport in
terms of jobs, wages/salaries, business revenues and tax receipts. The report also includes a
separate impact analysis for each of the surrounding communities at the Airport. 
Since 1987, the Port has undertaken a study of the economic impacts of the Seattle Harbor and
Seattle-Tacoma International Airport in approximate five-year intervals. Information from the
study provides defensible representations of the economic impacts associated with Port
activities and allows for informed policy discussion regarding the Port's current and potential
future role in supporting the economic vitality of the region. The study and related computer
models are also used in internal planning and evaluation of capital projects, comparison of
business operations and assessment of alternative land uses. The last study was completed in
2014. 
The Port advertised for consultants to conduct the 2017 Airport Economic Impacts study on
May 11, 2017 and proposals were received on May 22, 2017. Based on the consultants written
proposals, methods, assigned personnel, experience, and cost, the Port selected Community
Attributes Inc. for the study. 
On January 18, 2018, the Port will share the results of the 2017 Airport economic impacts study 
with our key stakeholders at State of the Port Breakfast. 
On January 30, 2018, staff and the consultant will present the results of the 2017 Airport
economic impacts study to the Commission.
