how the agreement is to be modified if the Parties cannot reach agreement) consistent with
the Parties' intent to the maximum extent allowable under law and consistent with the court

cost arising therefrom, including attorneys' fees, to enforce the provisions of this section,
all such fees, expenses, and costs shall be recoverable by the prevailing party. This
indemnification shall survive the termination of this Agreement.

"Airport" under the City's Comprehensive Plan.
2. If the Port acquires property located within the City after the effective date
of this Agreement, the Port shall follow the City's procedures identified in
City Resolution 97-001 to request amendment of the property's
Comprehensive Plan designation to "Airport." The City's Comprehensive
Plan may only be amended pursuant to procedures established by the
Community and Economic Development Director and no more frequently
than once each calendar year, except as provided in Chapter 16A.25.040 (C)
of the SeaTac Municipal Code (SMC) or state law.
C. Zoning Designations.

non-airport related commercial, industrial or light manufacturing
use, while maintaining compatibility with airport operations and
activities.

2. If the Port acquires property located within the City after the effective date
of this Agreement, the Port shall request a site specific rezone pursuant to
SMC 15.115.050 (and as authorized by 35A.63.170 RCW) to rezone the

the Port's application for a rezone of Port-owned property to the AVO or
AVC zoning designations in a timely and consistent manner pursuant to the
process found in SMC 15.115.050.
D. Airport Land Use Chart.
Airport uses allowed within the AVO and AVC zones are found in Appendix 3B,
AVO and AVC Allowed Land Use Chart and Definitions, of this Chapter.
3.4. Airport Activity Area (AAA).

utilized for Airport Operations in the future. The AAA Map shall be amended to
include some or all of these parcels in the AAA when these parcels are proposed
for use for airport operational uses. However, amendments to the boundaries of the
AAA shall only occur after the Port adopts the Sustainable Airport Master Plan
(SAMP) and commences development projects after project authorization, which
implements the South Aviation Support Area (SASA) component of the SAMP.
D. AAA "Edges" Properties.
1. Airport development located within the AAA shall address land use issues
associated with the "Edges" of the AAA. The "Edges" are defined as the

The Parties share an interest in coordinating, planning, and designing
development on Port-owned property that is located on the Edges. The
Parties further acknowledge the importance of ensuring that the Airport can
meet future capacity and operational requirements through the efficient
layout of airport facilities. The design of these facilities along the Edges
shall incorporate aesthetic treatment and screening, in balanced
consideration of future capacity and operational needs. In order to provide
flexibility to the Port, ensure compatibility with adjacent private and public
properties or roadways, and provide certainty and transparency to both
Parties, the following principles are established to guide current and future
Airport development along the Edges:
a. Minimize the height, bulk and scale and/or appearance of any
retaining walls by alternative design approaches including, but not
limited to, green walls, use of texture and color, or stepped walls.
b. Design project lighting with consideration to on-site and off-site
uses, taking care to provide illumination to serve building needs
while avoiding off-site glare and light pollution.
c. Minimize and mitigate visual impacts on adjacent right-of-way and
private or public properties through enhanced landscape screening,
open space and/or commercial development to form a continuous
screen.
d. Arrange new or remodeled buildings taking into consideration the
characteristics of the site and surrounding area to reduce the
perceived mass of the structures.
E. Federal Preemption of ILA Standards on Port-owned Property Located Outside of
the AAA.
Development on Port-owned property located outside of the AAA is exempt from
the development standards and regulations described in this Chapter and the SeaTac
Municipal Code if the development includes facilities or aids that support airport
and aircraft operations, or whose locations are fixed by function, as defined by the
FAA (FAA Advisory Circular 150-5360-9) or as defined by other federal
authorities with regulatory authority over these developments.
F. Previously Leased and Designed Developments Located on Port-owned Property
Located Outside of the AAA.
Any development to be located on Port-owned property that has already been
approved for a Port lease and designed in compliance with land use standards in
effect prior to the effective date of this Agreement is not subject to the terms of this

Agreement, provided that the permits have been properly issued and construction
commences within one (1) year after the effective date of this Agreement.
G. Application of Development Standards on Port-Owned Property Located Outside
the AAA.
All developments on Port-owned property located outside the AAA are subject to
the development standards of this Agreement unless exceptions described

needs.
4.2. General.
A. The City operates, maintains, and manages all City-owned Rights-of-Way (ROW).
The Parties have separate agreements concerning Port-owned infrastructure located
in the ROW.
B. The Port has the authority to manage, control, and govern roadways at Sea-Tac
Airport per the Revised Airports Act (Chapter 14.08 RCW) and other applicable
authorities. These roadways are located on public property owned by the Port.
C. The Port and the City disagree about the applicability and payment of
Transportation Impact Fees by the Port on development projects located within the
AAA. In order to resolve this dispute, the Parties agree to address Transportation
Impact Fees and Concurrency as set forth in this Chapter.
D. The City and Port staff who will serve as points of contact for transportation related
matters addressed in this Chapter are identified in Appendix 4A.
4.3 Transportation Impacts/Concurrency.
A. Transportation Impacts.
1. The Parties acknowledge that transportation impacts shall be addressed for
all Port development located within the City. The Parties further
acknowledge that development at the Airport within the AAA associated
with Air Operations Area, Airport Airfield Facilities, and Airport Terminal
Complex are unique trip generators.
2. The FAA Policies and Procedures Concerning the Use of Airport Revenue,
including FAA Grant Assurance #25, require that airport revenue can only
be used for the capital or operating costs of the airport, the local airport
system, or other local facilities owned or operated by the airport owner or
operator. In addition, FAA Grant Assurance #25 provides that the use of
airport revenue must be directly and substantially related to the
transportation of passengers or property. For these reasons, transportation
impact fees imposed by the City Code will not be charged to development
located within the AAA during the term of this Agreement.
3. The Parties agree that for all development located within the AAA,
including development that accommodates future growth, the Port shall use
the SEPA environmental review process to fully and appropriately assess
and mitigate transportation related impacts within the City.

4. All development on Port-owned properties located outside of the AAA shall
be subject to Transportation Impact Fees pursuant to Chapter 36.70A RCW
and Chapter 11.15 of the SeaTac Municipal Code.
B. Transportation Concurrency.
1. For all development located within the AAA, the Port shall use the SEPA
environmental review process to evaluate and address concurrency
requirements that relate to airport development.
2. All development on Port-owned properties located outside of the AAA shall
be subject to the transportation concurrency requirements of State law
(RCW) and the SeaTac Municipal Code.
4.4. Coordination and Cooperation.
A. Transportation Planning.
Both Parties benefit by coordinating their respective transportation planning efforts.
Therefore, the Parties commit to such coordination including, but not limited to:
maintenance and joint ownership of a regional travel demand traffic model,
collection and sharing of relevant transportation planning data and information, and
briefings to update each other's staff and elected officials on upcoming or on-going
transportation studies and projects.
1. Transportation Modeling.
It is essential that traffic planning studies led by either party are consistent
with each other's planning studies in regards to inputs and assumptions.
Therefore, the Parties shall create and maintain a jointly-owned regional
travel demand traffic model. Additionally:
a. Each party shall be responsible for all costs associated with its use
of the regional travel demand traffic model;
b. Each party shall maintain a detailed log of all changes made to the
regional travel demand traffic model and provide a copy to the other
party each time an update/change is made;
c. The Parties may share in the cost of labor intensive updates to the
regional travel demand traffic model that benefit both Parties, such
as incorporating new land use and economic data that change
fundamental model assumptions;
d. Each party shall make a good faith effort to coordinate significant
updates to the regional travel demand traffic model.
2. Information Sharing and Data Collection.
a. The Parties shall adequately inform each other about upcoming and
on-going transportation planning efforts in a timely manner. Each

Party shall provide briefings to the other party upon request.
Furthermore, the Parties shall act in good faith to initiate staff
briefings for the other party's benefit if there is a need to share
important information.
b. The Parties shall share transportation related data and information
as it becomes available, including but not limited to, traffic counts
or surveys.
B. Transportation Projects.
The Parties acknowledge the benefits of working together to pursue funding and/or
advocate for transportation related capital projects of mutual interest and/or benefit.
These projects may be sponsored by either party or other agencies.
1. Project Coordination.
The Parties share an interest in ensuring that transportation improvements
identified through environmental review or planning studies are included in
their respective capital programs. Prior to annual Commission adoption,
the Port shall review its Capital Improvement Program (CIP) with City staff.
The Port agrees to identify projects that may impact local access when
reviewing their CIP project list. Prior to annual City Council approval, the
City shall review its Transportation Improvement Program (TIP) with Port
staff.
2. Funding and Planning for Projects of Joint Interest.
The Parties shall support each other as a transportation project sponsor in
order to aid in the pursuit of grant funding for transportation projects of
mutual interest. The Parties shall also work collaboratively to advocate for
transportation projects of mutual interest and/or benefit.
C. Roadway Standards.
The Parties recognize the benefits of coordinating and integrating roadway
standards at appropriate locations in order to provide a more integrated, uniform
and aesthetically pleasing experience for SeaTac residents and the visiting public.
Therefore, the Port and City shall work together to identify opportunities to
implement and achieve this goal.
D. Local Public Access.
1. Maintaining sufficient motorized and non-motorized local public access to
and from the Airport is essential for SeaTac businesses and Airport
customers, visitors, and employees.
2. The Port is responsible for the planning, design, and construction of Airport
roadways.
3. The Parties acknowledge that the Port's ability to provide local public
access to the Airport is constrained by existing and planned facilities located

both on and off Airport property. However, since the number, type, and
location of Airport access points play a significant role in the efficiencies of
the local transportation system, it is in the interest of the Parties to closely
coordinate the creation or alteration of local public access, especially during
the pre-design phase of any projects.
E. Right-of-Way Access Management.
To increase security at the airport and improve the functionality and aesthetics of
the right-of-way within the City of SeaTac, the Port shall actively explore
opportunities to reduce the number of current non-public access points to City rightof-way
, with a priority on those access points that are no longer used or needed by
the Port. The Port, in coordination with the City, shall also actively explore
opportunities to combine multiple access points into single points of access.
4.5. Operational Planning.
A. Construction Traffic.
The City is responsible for reviewing and accepting traffic control plans involving
the City roadway system. The Port is responsible for reviewing and accepting
traffic control plans involving the Airport roadway system. Both Parties agree to
coordinate management of traffic when traffic control plans involve both Parties'
roadway systems, or traffic detours that impact the other party's roadway system.
B. Holiday/Special Events.
Traffic Management for peak holiday travel and/or special events shall be
coordinated and planned jointly by the City and the Port.
C. Emergency Management.
The Parties shall inform and coordinate with each other emergency management
activities that may impact each other's operations.

Port-owned property that becomes included within or immediately adjacent
to the AAA as the result of modification of the AAA boundary.
4. If a facility or property is deemed to be operationally essential to airport
operations, safety and security, the Parties may agree to change law
enforcement jurisdiction from the City to the Port, regardless of the
proximity of the property to the AAA. At the request of the Port, the City
and Port Police Chiefs will discuss and make a determination regarding
whether law enforcement jurisdiction shall be modified while ensuring that
public safety remains a top priority in any decision.
5. Any changes to law enforcement jurisdictional responsibility to a Portowned
property shall be agreed upon by the City and Port Police Chiefs.
The Port shall document and forward any changes in writing to the ILA
Reviewer, c/o King County Sheriff's Office Communications Center and
the E-911 Program Office. Notice sent by the Port shall include the parcel
numbers and street addresses where law enforcement jurisdiction is to be
modified so that adjustments can be made to the GIS files for the proper
routing of 911 calls.
7.4. Fire Emergency Planning and Operations.
Most fire agencies in King County, including the City and Port, have entered into the King
County Mutual Assistance and Interlocal Agreement, which establishes each agency's
mutual commitments and roles for assisting in fire calls and other emergencies. The Port
and City agree to review this King County Mutual Assistance and Interlocal Agreement at
least every five (5) years, or when requested by either party, to ensure that the needs of the
public are being served by the closest emergency response unit. The City and Port may
enter into additional agreements as deemed appropriate by their respective Fire Chiefs.
7.5. Permit Parking Program.
ILA-2 (Exhibit C, Section 5) dedicated 36.9% of the parking tax collected by the City to
certain transportation projects and related costs. Amendment #4 to ILA-2, Section B,
eliminated this specific allocation moving forward, and established a joint process to
identify projects for the remainder of these Parking Tax funds. The Port releases to the

City in full any interest or claim in these remaining parking tax funds, estimated to be $3.85
million. It is the City's intent to utilize these remaining funds for supporting the initiation,
implementation and ongoing operation of the Permit Parking Program and related
transportation improvements. The City agrees that this contribution by the Port represents
the appropriate level of participation in the design, capital costs and ongoing operations of
the Permit Parking program for the term of this Agreement.
7.6. Community Relief.
7.6.1. The Port will contribute $1.4 million annually to the City's General Fund for
community relief ("Community Relief Contribution"). The Parties acknowledge
that the Port's Community Relief Contribution is intended to provide the City
community relief with respect to public safety, including but not limited to police,
enforcement of traffic and parking regulations, and general enforcement of City
codes and ordinances not otherwise addressed in this Agreement. The Contribution
is to address public impacts associated with airport operations or businesses directly
serving airport passengers. Consistent with the Parties' intent concerning the
purposes of the Community Relief Contribution, and to foster the partnership
between the Parties, the City shall not request additional funding from the Port for
the matters covered by the Community Relief Contribution during the term of this
Agreement. Furthermore, the City agrees with the Port that the Community Relief
Contribution may be considered by the SEPA Lead Agency when determining the
appropriate mitigation with respect to police and enforcement of parking and traffic
regulations.
7.6.2. The Parties recognize the importance of working together in order to meet each
Parties' commitments and obligations under this Agreement. Furthermore, the
Parties agree that mutual cooperation, partnership, and acting in good faith is
essential for this Agreement to be successful, and that the Dispute Resolution
provisions established in Chapter II, Subsection 2.4. shall be utilized when the
Parties cannot agree. In consideration of the Port's Community Relief
Contribution, the City agrees that the annual Community Relief Contribution may
be suspended by the Port (but not forfeited) if the City commences litigation against
the Port concerning the subjects covered by this Agreement without first utilizing
Dispute Resolution. Furthermore, any suspended Community Relief Contribution
shall be payable to the City within thirty (30) days of completion of such litigation,
or some earlier time that is mutually agreed to by the Parties. Appeals under the
State Environmental Policy Act (SEPA) shall not be considered litigation as
contemplated by this Subsection.
7.7. Economic Opportunity and Workforce Development.
The City and the Port shall jointly and cooperatively work to support economic opportunity
and workforce development in the City for businesses and employees associated with
Airport operations. One such effort will be in the furtherance of the requirements of the
SeaTac Employment Standards Ordinance (codified in Chapter 7.45 SMC), including, but
not limited to, education and outreach efforts to both employees and businesses located at
the Airport. These efforts may be further defined in a letter of agreement between the City
and the Port to more specifically delineate each party's roles and responsibilities.
