PSERN Project

The PSERN Project is the $293M capital project to upgrade and expand the emergency radio system for public safety response in King County, Washington, creating PSERN. The Project is housed in the King County IT Department’s Emergency Radio Communications Division. When the Project is completed in 2023, operations of the new PSERN System will transfer to the PSERN Operator. If you have any questions, please contact or visit the Contact Info page.

History of PSERN Project

The lack of radio system standardization across King County and the eminent obsolescence of the technology, eventually led King County voters to approve the 2015 Proposition No. 1: Regular Property Tax Levy for Emergency Public Safety Radio Network Replacement Project by two thirds of the vote. This formed the PSERN Project, to upgrade and expand the system, including transitioning from the KCERCS analog system to the new PSERN digital system. This new system will have a lifespan of at least 20 years from the completion of the Project, but the sole PSERN Operator will allow it to be more adaptive as technology advances.
