COMMISSION AGENDA MEMORANDUM ACTION ITEM Item No. Date of Meeting DATE: May 11, 2026 TO: Stephen P. Metruck, Executive Director FROM: Jason Berg, Aviation Real Estate & Portfolio Manager Eric Schinfeld, Senior Manager, Federal Government Relations 8h June 9, 2026 SUBJECT: King County ILA Renewal For-Hire Transportation Regulatory Services Action Memo ACTION REQUESTED Request Commission authorization for the Executive Director to enter into an Interlocal Agreement (ILA) with King County for For-Hire Transportation Regulatory Services. This ILA will be effective for one year from the date of execution, and shall automatically renew from year to year unless either party terminates with 30 days written notice to the other party. EXECUTIVE SUMMARY Changes in King County policies related to for-hire transportation require the Port and King County to update their long-time ILA to accurately reflect these updates. In particular, the ILA has been drafted to incorporate general updates and to add the new chapter of King County Code, chapter 6.65. The update has been negotiated between the Port and King County, and has been reviewed and finalized by the Port's Legal Department and Aviation Division staff. DETAILS The Port of Seattle and King County executed an ILA that went into effect on April 9, 1987 for the enforcement of taxi and for-hire transportation regulations on airport property. King County continues to regulate the for-hire transportation industry by providing regulatory services for 16 cities as well as the Port of Seattle at Seattle-Tacoma International Airport. The County has a similarly long history of working with the City of Seattle to license and enforce these respective regulations. In December 2023, King County Executive Dow Constantine signed four ordinances related to forhire transportation. They include: Template revised January 10, 2019. COMMISSION AGENDA - Action Item No. 8h Meeting Date: June 9, 2026 Page 2 of 2 • Ordinance 19699, which updates King County Code (KCC) chapter 6.64 provisions related to transportation network companies, drivers, and vehicles, to better align with state law and to remove regulations related to taxicabs and for-hire vehicles from the chapter. • Ordinance 19700, which establishes a new chapter in King County Code to regulate taxicab and for-hire vehicle operators. The goals in establishing this new chapter are to update and modernize the regulations for this part of the industry, to create a more regional licensing model for companies, drivers and vehicles, to formally begin the transition to new technology via smart taximeters systems, to provide greater flexibility for individual companies to implement more competitive fare strategies like upfront fares and dynamic pricing, and to improve alignment with the City of Seattle's regulatory program by reducing the complexity of navigating similar but slightly different code requirements. • Ordinance 19692, which authorizes the Executive to enter into updated interlocal agreements with local jurisdictions to provide for-hire regulatory services. In addition to general updates, the new ILA incorporates the newly adopted chapter in King County Code. • Ordinance 19693, which authorizes the Executive to enter an updated interlocal agreement with the City of Seattle to regulate the for-hire transportation industry, adds the new chapter created in King County Code and a companion chapter in Seattle Municipal Code, and delineates the roles and responsibilities between the City and King County. The existing ILA between King County and the Port of Seattle currently only refers to KCC chapter 6.64. A new interlocal agreement has been drafted to incorporate general updates and to add the new chapter of King County Code, chapter 6.65.
