This bill establishes a new section in chapter 82.14B RCW to provide funding for municipalities participating in a regional 911 emergency communications system. Specifically, it mandates that counties located east of the Cascade mountains with populations between 530,000 and 1,500,000 must transfer a portion of their tax revenues to local governments that operate municipal public safety answering points. The amount transferred will be based on the tax revenue sourced from the local government's jurisdiction, and until the state can accurately apportion these taxes, the transfer will be based on the same percentage that cities receive under a related tax law.

The bill outlines that these transfers must occur quarterly and defines a "regional 911 emergency communications system" as one operated by a county that handles emergency calls for multiple local law enforcement and fire agencies. This legislation aims to ensure that local governments receive adequate funding to support their emergency response capabilities through the regional 911 system.
