The Radio Replacement Project officially began with the successful passing of Snohomish County Proposition #1 in November of 2018.  The goals of the Radio Replacement Project are simple but significant:

  1. Upgrade and/or replace the existing Emergency Radio System – and its supporting sub-systems – to bring the systems back to a level supported by vendors to ensure reliability and support
  2. Upgrade and/or replace the existing user radio equipment on behalf of our agencies
  3. Maintain the level of system performance and features relative to the current system

The Radio Replacement Project has six major areas of technical focus:

  1. Trunked radio system upgrades, replacements, and expansions
  2. Conventional radio system updates
  3. Alphanumeric paging system updates
  4. Portable and mobile user radio replacements
  5. Fire station alerting radio replacements
  6. Supporting microwave system upgrades and enhancements

To implement the above many of our existing site locations require other work to site systems including AC/DC power and tower strengthening.  This is a multi-year project, and will involve both sequential and parallel work efforts.

Measuring Success

The definition of success is often difficult to define in a project of this magnitude and duration.  Systems that support the needs of First-Responders are always adapting due to the ever-changing needs of their mission.  Therefore, our measurement of success is both in what we implement, but also in how we implement it.  To that end, we wish to document our definition of success so that we can use it as our guiding principles when difficulties are encountered:

  • We recognize the urgent need to complete this work, therefore a responsible and timely implementation must be prioritized
  • We must ensure that the goals and requirements of the system are met in a quantifiable and measureable manner, yet are open to change as the needs of our agencies change
  • We are accountable to both our First-Responders and the citizens of Snohomish County to implement this system and future programs in a fiscally-responsible manner
  • We will regularly communicate our progress to our stakeholders so that all agencies can share in the decisions that can have an impact to their operations
