Emergency Notifications

The City has partnered with Nixle to provide an Emergency Notification System to alert residents in real-time about critical emergency information and community advisories in La Habra Heights.

Citywide Reverse 911 Test


A Citywide test of AlertLHH’s Reverse 911 system will occur on October 20, 2020 at 1:00 PM. Residents and business will receive a test message through multiple forms of communication (web-based media, text message, and telephone calls). This test is being conducted to determine the resilience of the system and to allow residents to be familiar with the system when an actual emergency does occur.

Residents will receive two consecutive phone calls with a recorded message announcing the test. The second phone call occurs to allow individuals and voicemail systems to listen to the message again. After the conclusion of the message, residents will be asked to confirm receipt of the message.  The City urges residents to select the option as it will provided accurate results for this test. A text message and e-mail  will also be distributed concurrently with the recorded phone call.  Residents are advised not to panic.
