Concord emergency alerts start with the county warning system
Concord residents can use Contra Costa County's Community Warning System, the city's OES page, and CERT information as the backbone for local emergency planning.
Concord sits in the middle of a lot of East Bay movement. BART, busy roads, school routes, shops, older neighborhoods, and the open hills toward Mount Diablo all meet here. On a hard day, people need to hear what action fits their area.
The Office of Emergency Services page connects residents with Contra Costa County’s Community Warning System. The warning system can send basic incident info and tell people what to do next. That may mean shelter in place, leave, lock down, or avoid an area.
Concord also has CERT information for residents who want more training. That can be useful in a city where homes, apartments, schools, and workplaces may all be part of the same local plan.
For most homes, the first step is easy. Register for alerts. Save the OES page. Talk through pets, medicine, school pickup, and who checks on someone who may need help.
