13    SECTION 1.  Purpose. 
14 
15    This policy directive establishes guidance on ground transportation at the Seattle-Tacoma 
16    International Airport (Sea-Tac) including principles, goals, monitoring, and reporting; creates an
17    Annual Ground Transportation Progress Report; affirms airport commute-trip-reduction (CTR)
18    goals; and establishes a transportation management association. 
19 
20    SECTION 2.  Definitions. 
21 
22    When used in this policy directive, the following words and phrases shall have the meanings
23    given below unless the context in which they are included clearly indicates otherwise: 
24 
25    "Commute-tripreduction (CTR)" refers to the regulations developed under the Washington
26    Administrative Code 468-63-010, with the intent to reduce automobile-related air pollution,
27    traffic congestion, and energy use through employer-based programs that encourage the use of
28    alternatives to single occupant vehicles travelling during peak traffic periods for the commute
29    trip. 
30 
31    "Ground transportation"means non-aviation activities that relate to travelling to and from the
32    airport. 
33 
34    "Scope 3 greenhouse gas (GHG) emissions" refers to the GHG Protocol Corporate Standard that
35    classifies  a  company's  GHG  emissions  into  three  'scopes'.  Scope  1  emissions  are  direct
36    emissions from owned or controlled sources. Scope 2 emissions are indirect emissions from the
37    generation of purchased energy. Scope 3 emissions are all indirect emissions (not included in 
38    scope 2) that occur in the value chain of the reporting company, including both upstream and
39    downstream emissions. 
40 
41    SECTION 3.  Scope and Applicability. 
42 
43    This policy directive applies to all activities related to ground transportation to and from Sea-
44    Tac. 
45 
46    SECTION 4.  Responsibilities. 
47 
48    The Executive Director shall engage in the following activities in pursuit of this policy directive,
49    either directly or by appropriate delegation of authority: 
50 
51            A.  Ensure the Ground Transportation principles are applied to decisions on ground
52    transportation at the appropriate time and manner. 
53 
54            B.  Shall strive to achieve the goals enumerated below. 
55 
56            C.  Provide an Annual Ground Transportation Report to the Commission. 

Port of Seattle Ground Transportation Policy Directive                                                               Page 2 of 4

57    SECTION 5.  Policy. 
58 
59            A.  Ground Transportation Principles. The Federal Aviation Administration regulatory
60                guidance directs an airport fee and rental structure designed to make the airport as
61                self-sustaining as possible. In this context, self -sustaining is generally interpreted as
62                applying  fair  market  value  commercial  rates  under  the  particular  airport's 
63                circumstances. This reduces the airport's reliance on federal funds and local tax
64                revenues. In developing recommendations to the Commission governing ground
65                transportation, Port staff shall, alongside the regulatory guidance, use the following
66                guiding principles in managing ground transportation activities at Sea-Tac. 
67 
68                    (1) Reduce  passenger  and  commuter  trips  and  lower  carbon  emissions  to
69                        achieve Port GHG-reduction goals and reduce negative community impacts. 
70 
71                    (2) Reduce airport drive and roadway congestion, improve ease of access to the
72                        airport,  increase  transportation  options,  and  improve  the  customer
73                        experience. 
74 
75                    (3) Support equity considerations by promoting living wage jobs, equal business
76                        opportunities, and accessibility for people with disabilities. 
77 
78            B.  Ground Transportation Goals. Port staff shall apply the principles in Section 5(A) and
79                implement strategies to achieve the following ground transportation goals.
80 
81                    (1) Reduce curbside private vehicle pickup/drop off from 41  percent  to 30 
82                        percent of mode share by 2030.
83 
84                    (2) Reduce Scope 3 GHG emissions from passenger vehicles to 50 percent of
85                        2007 levels by 2030. 
86 
87                    (3) Maintain a maximum 15-minute travel time from the airport clock tower to
88                        terminal curb or parking garage. 
89 
90            C.  The Port is committed to airport employee CTR. 
91 
92                (1) The Commission affirms the Port's commitment to achieving the drive-alone rate
93                    goal for Port employees at the Airport established by the CTR program currently
94                    set by the City of SeaTac at a 65 percent drive-alone rate. 
95 
96                (2) The Port shall establish a Transportation Management Association (TMA) by
97                    2020 and make membership available to all employers operating at the Airport.
98                    The TMA will support commute reduction strategies that go beyond minimum
99                    CTR requirements and facilitate efficient movement of employees to and from

Port of Seattle Ground Transportation Policy Directive                                                               Page 3 of 4

100                   the Airport. The primary goal of the TMA will be to suppo rt the reduction of
101                   drive-alone rates for employees that work at the Airport.
102 
103                (3) The Port shall develop and implement parking management strategies and tools
104                   to help achieve airport CTR goals, reduce drive-alone rates, and achieve the
105                   desired mode split. 
106 
107    SECTION 6.  Program Evaluation. 
108 
109    Port staff shall prepare and deliver to the Commission an Annual Ground Transportation
110    Progress Report by June 30th of each year that includes progress and recommendations to
111    better achieve the policy outlined in Sections 3 A. B. and C. 
112 
113    SECTION 7.  Fiscal Implications. 
114 
115    Fiscal implications shall be reviewed by the Executive Director annually, at a minimum, to ensure
116    the implementation of the policy directive is adequately resourced and shall submit a budget
117    request as appropriate.
