diligently seek to modify this Agreement (or seek the court's determination of whether
and 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 decision. If there are changes in applicable law, court decisions, or federal

2.11. Indemnity and Hold Harmless
To the extent permitted by law, the Port and the City shall protect, defend, indemnify,

judgment, and/or awards of damages, arising out of, or in any way resulting from,
Indemnifying Party's negligent acts or omissions. Neither the Port nor the City will be
required to indemnify, defend, or save harmless each other if the claim, suit, or action for
injuries, death, or damages is caused by the sole negligence of the other party. Where
such claims, suits, or actions result from concurrent negligence of the Port and the City,
the indemnity provisions provided herein shall be valid and enforceable only to the extent
of the Port's or the City's own negligence. The Port and the City agree that its
obligations under this subsection extend to any claim, demand, and/or cause of action
brought by, or on behalf of, any of its employees or agents. For this purpose, the Port and

the City, by mutual negotiation, hereby waives, with respect to the other party only, any
immunity that would otherwise be available against such claims under the industrial
insurance provisions of Title 51 RCW. In the event that the Port or the City incurs any
judgment, award, and/or 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.
2.12. Coordination; Notice.
Each party shall designate in writing a contact person for implementation of this
Agreement. Any notice or demand under this Agreement shall be in writing and either
(a) delivered personally, (b) sent by electronic transmission with confirmation, or (c)
deposited in the U.S. mail, certified mail, postage prepaid, return receipt requested, and
addressed to the designated contact person.
2.13. Time of Essence.
Time is of the essence of this Agreement in every provision hereof. Unless otherwise
stated, "days" shall mean calendar days. If any time for action occurs on a weekend or
legal holiday, then the time period shall be extended automatically to the next business
day.
2.14. Headings.
The headings are inserted for reference only and shall not be construed to expand, limit or
otherwise modify the terms and conditions of this Agreement.

DEVELOPMENT
STANDARDS

CHAPTER III: Land Use and Development Standards
3.1. Purpose.
The purpose of this Chapter is to establish a coherent and cooperative system for the
Parties to express their agreement concerning the identification and management of land
uses and development standards for Port-owned property located within the City. These
standards include comprehensive planning, zoning, regulatory controls, and exceptions.
3.2. Chapter Review.
The Parties shall review this Chapter every two (2) years to determine whether any
amendments are necessary.
3.3. Comprehensive Planning, Zoning, and Land Uses.
A. Comprehensive Plan and Zoning Designations.
One comprehensive planning designation and two zoning designations shall apply
to Port-owned property located within the City as described below.
B. Comprehensive Plan Designation.
1. Port-owned property located within the City shall be designated as
"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. 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.
1. Port-owned property located within the City shall be zoned either "AVO--
Aviation Operations" or "AVC--Aviation Commercial". The descriptions
of the AVO and AVC zones are as follows:
a. Aviation Operations (AVO).
The Aviation Operations zone is designated for facilities or
structures that provide safe and efficient movement of the traveling
public, employees, and goods and services associated with airport
operations.
b. Aviation Commercial (AVC).
The Aviation Commercial zone is designated for airport related
and 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 RCW 35A.63.170) to rezone the
property to either AVO or AVC. The City will facilitate 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).
A. A map ("AAA Map" as depicted in Appendix 3A) has been created to identify
Port-owned properties that will be included within the Airport Activity Area
(AAA). The AAA consists of parcels that are:
1. Generally used for airport operational uses; or
2. Physically connected to the airfield, including facilities or aids that
support the airfield or aircraft operations, or airfield development whose
location is fixed by function as defined by the Federal Aviation
Administration or other federal agency;
B. Properties located within the AAA are exempt from the development standards
and regulations described in this Chapter and the SeaTac Municipal Code.
C. Parcels designated as "Future AAA" on the AAA Map have the potential to be
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 operations. 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 which implement 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
locations where new development on Port-owned property is located
adjacent to, or abuts:
a. public right-of-way, or
b. property owned by public agencies other than the Port, or
c. privately-owned property.
2. Policies and Standards for Development of Edges Properties.

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 the AAA is not subject to
the development standards of this ILA if the development includes facilities or
aids that support airport and aircraft operations, or whose locations is fixed by
function, as defined by the FAA 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 are not subject to the terms of
this Agreement, provided that the permits have been properly issued and
construction commences within 1 year of 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

elsewhere in this Agreement apply.

the Port will work together to address current and future transportation related matters
and 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 cannot be charged to development
located within the AAA.
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. Public 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 access points to City right-of-way,
with a priority on those access points that are no longer used or needed by the
Port. The Port, in coo rdination 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.

REGULATIONS

CHAPTER VI: Environmental Regulations
6.1. SEPA.
A. Lead Agency Status.
The City and Port recognize that an important purpose of this Agreement is to
establish procedures to facilitate and expedite development of Port properties.
Part of the development review process is to ensure projects comply with the
State Environmental Policy Act (SEPA), Chapter 43.21C RCW/197-11 WAC. To
eliminate the need for case-by-case discussions in the future, the Parties agree that
service as SEPA lead agency on port-owned properties will be as follows:
1. For projects located within the AAA boundaries, the Port will serve as
SEPA lead agency.
2. For proposals for private development on Port property located outside the

release of SEPA documents (both SEPA checklists and SEPA
determinations). The Port will not issue a SEPA determination

prior to expiration of this two-week time period.
b. Proposals located outside the AAA.
i. If the City is the lead agency, the City will process the
SEPA checklist and development application pursuant to
the requirements of applicable City code and state law,
including administration of the required public notification
and comment periods. The Port's SEPA Responsible
Official or designee will serve as the Port's point of
contact. The Port will be given the opportunity to review
public comments and draft City SEPA documents prior to
the City's release of these documents. If requested to do so
by the Port, the City agrees that it will meet to review
public comments and discuss the Port's concerns prior to
the City's release of SEPA documents. The Port shall
provide written comments, if any, within two (2) weeks of
its receipt of SEPA documents. The City shall not issue a

PUBLIC SAFETY &
GENERAL
SERVICES

CHAPTER VII: Public Safety & General Services
7.1. Police Jurisdiction and Authority.
The City and Port have, through their respective authorities and jurisdictions, established
their own police forces to provide police services to their own jurisdictions. The City and
Port Police Departments are authorized to engage as outlined in the Mutual Aid Police
Powers Act, Chapter 10.93 RCW to provide emergency assistance to each other as
needed.
7.2. Police Emergency Planning and Operations.
The Parties agree that there is mutual benefit to frequent communications about crime,
civil disorder, Homeland Security and public safety issues which may have shared
impact. Therefore, Parties will establish and maintain working relationships that support
such communication.
The Parties shall strive to visit each other's worksites annually, for guided familiarization
tours consistent with local security needs and as feasible to conduct joint, pre-emergency
planning and training drills.
When planned events are foreseen to impact both jurisdictions (such as dignitary visits,
Seahawks, and protests) the Parties agree to work together to develop/implement
strategies for successful resolution. If the event is permitted through the City's special
event permit process, the City may assist the Port in recovering associated costs.
The Parties agree to develop agency specific event plans that will not negatively impact
the resources of the other party. If it becomes obvious that an agency specific event or
event plan will negatively impact the other party, the Party that will be impacted will
notify the other Party of the potential impacts. In such cases, the Parties agree to work
together to mitigate the impacts. All reciprocal services performed to mitigate the
impacts shall be rendered without reimbursement unless the Parties agree to reimburse
each other.
The Parties agree to review the contents of this Agreement every five (5) years or as
requested by either party during the term of the ILA.
7.3. 911 Calls for Police Service.
The 1999 911 Settlement Agreement is now terminated. The intent of thisSection is to
demonstrate collaborative philosophical and operational agreements between the Port and
City Police Departments and their respective dispatch centers, seeking to ensure timely
police responses for the benefit of public safety. The Parties also seek to reduce
jurisdictional confusion for the Parties dispatch centers and first responders because a
lack of clarity about jurisdictional response can negatively impact public safety.
The Parties agree to the following pertaining to law enforcement jurisdiction and routing
of 911 calls for police service:

1. The Port shall have law enforcement jurisdiction for Port-owned
properties within the AAA, the Airport Employee Parking Lot located in
the 15000 Block of 24 Avenue S., and the Port's Consolidated Rental Car
Facility. 911 calls for police service at these properties shall be routed to
the Port Dispatch Center for response by the Port of Seattle Police.
2. Unless otherwise agreed upon, the City shall have law enforcement
jurisdiction for Port-owned properties which are not immediately adjacent
to the AAA, and 911 calls for police service shall be routed to the King
County Sheriff's Office for response by the City Police.
3. Law enforcement jurisdiction shall change from the City to the Port for
any 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 in which 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 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 pay $1.4 million annually to the City for community relief
("Community Relief Payment"). The Parties acknowledge that the Port's
Community Relief Payment is intended to provide the City with community relief
with respect to public safety, including police, enforcement of traffic and parking
regulations, and general enforcement of City codes and ordinances not otherwise
addressed in this Agreement, for impacts associated with airport operations or
businesses directly serving airport passengers. Consistent with the Parties' intent
concerning the purposes of the Community Relief Payment, 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 Payment during the
term of this Agreement. The City shall also provide the Port with an annual
financial accounting of the use of Community Relief Payments, including any
unspent balance. Furthermore, the City agrees with the Port that the Community
Relief Payment 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 Payment,
the City agrees that the annual Community Relief Payment 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. Appeals under the State Environmental Policy Act shall not be
considered litigation as contemplated by this Chapter.
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 SMC 7.45),
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.
