Any person desiring to bid on any county contract must register with the purchasing manager and pay an annual registration fee of $20. The County is seeking proposals which best provide a comprehensive, intuitive, centralized warning system. This system is expected to integrate National Weather Service (NWS) warnings, existing outdoor siren systems, automated emergency notification systems (to include telephone, text, email, and TDD/TTY), the Emergency Alert System, and an email alerting system.
