If there was an emergency in your neighborhood, how would you find out?

Many cities and counties have a notification system that will call your home phone and text or call your mobile phone when there is a fire, flood or other emergency situation.


Adams County uses the CodeRed system to contact residents for evacuation notices, bio-terrorism alerts, boil water notices, and missing child reports. Learn more here.


Arapahoe County said residents and businesses with landline phones are already listed in Arapahoe County's 911 database, and are therefore automatically included in the notification system. You may sign up to register mobile devices here.
