contracted services. Based on the 2025 annual total of 189 infractions, estimated 2027 infraction
court and prosecution expenses are $39,387.60 and for 521 parking citations estimated expenses
are $19,256.16. The total estimated expense are $710,955.37. Total annual expenditures will
vary based on actual case volumes.
The proposed six-year ILA establishes these rates for January 1 through December 31, 2027.
Beginning January 1, 2028, rates will be adjusted annually based on the Consumer Price Index for
Urban Wage Earners and Clerical Workers (CPI-W) for the Seattle-Tacoma-Bellevue area,
measured from June of the prior year to June of the current year. Annual adjustments will be
subject to a minimum increase of 2% and a maximum increase of 6%. The City will notify the Port
of adjusted rates by September of each year to support annual budget planning and provide
greater cost predictability.
Public defense services are provided by Stewart MacNichols Harmell, Inc., PS under a separate
contract and are not included in the proposed SeaTac court and prosecutor rates or ILA
authorization. The Port’s Legal Department administers legal services contracting under the
applicable Delegation of Authority under Section 9, Legal Services, Claims and Other
Representation.
JUSTIFICATION
The Interlocal Agreement supports the Century Agenda goals:
1. Goal 2, objective 3: Continuously improve the operational efficiency and customer
experience at SEA.
2. Goal 6, Objective 16: Advance the Port’s dedication to employee safety.
3. Goal 6, Objective 18: Partner and engage with external stakeholders to build healthy,
safe, and equitable communities.
Since 2021, the Port has used SeaTac Municipal Court to adjudicate misdemeanor cases and
infractions originating within SeaTac, including SEA. The department handled 586 criminal cases
in 2024 and 592 in 2025, an average of 589 cases annually (approximately 49 per month). Many
incidents at SEA involve property or disorder offenses, including theft and trespassing.
Additionally, SeaTac Municipal Court adjudicates infractions and parking citations for the Port.
Prior to our SeaTac ILA, when referring in-custody cases to KCPAO we are required to book the
defendant into the King County Jail. Due to changes in the King County Jail policy during 2020 and
2021, we were severely limited when we could book an in-custody arrest. Therefore, many
offenders at SEA were arrested, escorted off property, released, and returned soon thereafter to
the airport. Offenders often returned after leaving and have committed more serious crimes.
An interlocal agreement with Sea-Tac Municipal Court enables the Police Department to refer
misdemeanor cases for prosecutorial and court services and will enable the department to book
in-custody arrests into South Correctional Entity (SCORE).
