Beneath the bright lights of the Las Vegas Strip lies a hidden underground world. An estimated 1,200 to 1,500 people experiencing homelessness live in the flood control tunnels under the city, according to multiple reports. These tunnels, which stretch for about 600 miles, were designed to divert flash floodwaters but have become one of America’s most unconventional homeless shelters.
Why People Live in Las Vegas Flood Tunnels
Las Vegas has a well-known homelessness crisis, and the tunnel system offers some residents an alternative to living on the streets. Here’s why many choose to live below ground:
-
Shelter from Extreme Heat and Cold: In a desert climate where temperatures regularly exceed 110°F in the summer, the tunnels offer relief from the elements.
-
Privacy and Safety from Law Enforcement Sweeps: Individuals can avoid frequent evictions and citations for camping in public spaces.
-
Community and Stability: Despite the harsh conditions, many tunnel dwellers build makeshift homes using plywood, scrap metal, and furniture—creating a sense of home and belonging.
Dangers of Living in Flood Control Tunnels
Living in these tunnels comes with serious risks:
-
Flash Flooding: The tunnels can fill rapidly during storms, washing away homes and belongings—and posing life-threatening danger.
-
Health Risks: Limited access to hygiene, along with exposure to extreme dampness and trash buildup, can lead to infections and chronic illness.
-
Substance Use and Mental Health: Outreach workers report widespread addiction to methamphetamine and opioids, especially fentanyl and “tranq” (xylazine), a veterinary sedative now found in street drugs.
Outreach and Support
Several nonprofits are working to support people living in the tunnels:
-
Shine a Light Foundation: This group offers supplies, hygiene kits, and paths toward housing. Volunteers regularly walk the tunnels to provide direct assistance.
-
Care Complex and HELP of Southern Nevada: Offer transitional housing and access to addiction treatment and counseling.
Is There a Way Out?
Efforts to address homelessness in Las Vegas are ongoing, but challenges persist. While some have successfully moved into housing with the help of nonprofits, many remain underground due to barriers like:
-
Lack of identification
-
Criminal records
-
Shortage of affordable housing
-
Mental health challenges
Conclusion
The Las Vegas flood tunnels are more than just infrastructure—they are home to a forgotten population. While some find temporary relief underground, the risks are undeniable. As the city continues to grapple with a growing homelessness crisis, organizations and volunteers play a critical role in offering hope, resources, and a potential path back to the surface.
