The El Dorado County Sheriff’s Office of Emergency Services (OES) is excited to announce that they have recently acquired Perimeter Platform to bolster their emergency operations and improve communication channels with the public during critical situations. In collaboration with local fire districts and Cal Fire, they’ve worked diligently with Perimeter to segment the County into named zones within this innovative online mapping program. These zone names have been carefully chosen to aid in community recall and facilitate swift action when needed.

Accessible via Perimeter Map (, the platform provides a comprehensive array of vital information for residents. By simply enabling location services or entering your address, you can locate your position with a blue dot on the map, granting you instant access to critical data such as evacuation zones, routes, road closures, shelter locations, and more. We encourage everyone to take note of their designated zone for prompt action in emergencies.

Perimeter serves as a centralized hub for essential information during crises, particularly wildfires. No registration is required, ensuring accessibility for all. Furthermore, since our mapping covers the entire County, you can stay informed about evacuation orders across various areas. This feature can prove invaluable for assessing proximity to affected zones or monitoring the safety of loved ones residing elsewhere in the County.

It’s important to note that while Perimeter provides comprehensive mapping services, it is NOT an alerting platform. Emergency alerts will continue to be disseminated through El Dorado County Emergency Alerts powered by Rave. Nevertheless, they will include Perimeter’s link in the alerts to facilitate swift access to critical information. We encourage members of our community to bookmark the Perimeter website for rapid retrieval during emergencies. For instance, if you detect smoke in the air, a quick visit to Perimeter can provide clarity on evacuation statuses.
