Peace of mind when moments matter

Life can change in a moment, so it's important for emergency response personnel to be able to connect with residents during an emergency. Changes in technology are allowing governments to do so in more ways than ever before.

In an effort to take advantage of new technology and to continue to ensure accurate crisis communication with residents, the Town of Castle Rock and all other Douglas County agencies are transitioning to a new mass notification system called CodeRED.

Safety in numbers, connecting during crisis situations

CodeRed is a high-speed telephone emergency notification system that allows public safety personnel to send messages directly to residents - whether they are home or away - during an emergency. It uses geo-tracking to target specific areas with prerecorded phone messages, emails or texts.

CodeRED alerts may be implemented in situations such as police activity in the area, wildfires or other emergency incidents. However, the system does not include weather alerts. The Town encourages our residents and businesses to use NOAA weather radios, subscribe to any of the free weather apps, and/or monitor local media for information during severe weather.

In order for CodeRED to perform at its best, it needs an accurate database of contact information, associated with addresses. To ensure your information is included in this database, you must sign up.

Required information

Required information includes:

  • First and last name
  • Street address (no P.O. Boxes), city, state, ZIP code
  • Primary phone number.

All data will be kept confidential.

Residents can also sign up using cell phone numbers and emails, because dispatch centers can also use CodeRED to send messages via text message or email. Signing up allows residents to set their contact preferences. Should residents move, they will need to register again with their new address.

CodeRED will alert people of incidents in their area. The Town also uses its Facebook and Twitter accounts to keep the public updated on events, news and emergencies. Visit Facebook and follow the Town @CRgov.
