September is National Preparedness Month!

Emergencies and disasters don’t always come with much warning. Taking a few steps now can make a big difference in how you, your family, and your community respond when the unexpected happens.

Throughout September, Lewisville Emergency Management will be sharing practical tips, resources, and local preparedness events to help you get ready before disaster strikes. We’ll focus on simple steps you can take at home, like building an emergency kit, knowing how to receive emergency alerts, creating a family emergency plan, and other ways to help you and your loved ones be ready.

Preparedness isn’t about being ready for everything. It’s about knowing what to do, having a plan, and taking steps now so you’re ready to act when it matters most.

When individuals, families, and neighborhoods prepare together, we help build a stronger, safer, and more resilient Lewisville.

This year, FEMA’s National Preparedness Month theme is “Americans Stand Ready,” encouraging communities across the country to take an active role in preparing for emergencies.

So, Lewisville: are you ready? Follow along throughout September and take steps to become !

Preparedness starts with you.

As part of this routine maintenance, if a natural gas leak is discovered, crews will investigate and grade the leak. If a Grade 1 (hazardous leak) is found, immediate action will be taken to eliminate the hazard. Grade 2 and 3 leaks are monitored and scheduled for repair based on state and federal guidelines.
