City of Port of Seattle, 
This letter is to provide you with 2023 detention rates for housing your inmates in King County jail facilities.
Rates were prepared pursuant to the Interlocal Agreement between the County and King County cities. 
Due to continued COVID-19 population restrictions, the Department of Adult and Juvenile Detention is
again only employing basic annual inflation in 2023, rather than implementing a full cost reset. 
In addition, the Jail Services Agreement between your jurisdiction and King County is set to expire at the end
of 2022. For 2023, we will be offering a two-year contract which will be substantially like our current contract. 
Today, we are providing forecasted 2023 jail rates. While our council will have final approval of our rates, we
are optimistic the figures below will not be substantially different, if at all. Once we have final approval from
the council, we will reach back out with both the rates and a contract for your leadership to sign. The rates
being proposed, and the methodology follows our current Jail Services Agreement with your agency. 
Rates effective January 1, 2023, through December 31, 2023 
The Exhibit III Calculation of Fees, Charges and Surcharges, in the Interlocal Agreement specifies the fees,
charges and surcharges as well as the Offsite Medical Charges, the City shall pay. Also, Exhibit III c., i.,
denotes that King County will increase the Maintenance charge to capture the cost of capital expenditures
that benefit jail operations. In 2023, the debt service for the Courthouse Seismic Stabilization Project
(CSSP) is $1.05 and the debt service for the Integrated Security Project (ISP) is $5.21. For the period of
January 2023 through December 2023, the rates are as follows:
