Public safety
Hidden Hills sits in a Very High Fire Hazard Severity Zone. The City’s wildfire posture is the most consequential public-safety work it does, and the framework that protects residents is the strictest in California.
Ordinance 393: the wildfire framework
Evacuation routes & assembly points
Primary evacuation route exits Hidden Hills via the Long Valley Road gate to Calabasas Road; secondary route follows Spring Valley Road to Mureau Road. Residents should choose the route appropriate to the wind direction announced by City staff during an active incident.
