The Fires That Wrote Santa Clarita's Zone Zero Rules
The Sand Fire: two weeks on the city's eastern edge
It started on July 22, 2016, near Soledad Canyon Road and Sand Canyon Road, in 110-degree heat with sustained wind. Within days the Sand Fire had burned across more than 41,000 acres of the canyons east of the city.
Eighteen homes were destroyed and two people were killed. Roughly 10,000 homes went under evacuation orders, with Sand Canyon, Placerita Canyon, and Little Tujunga Canyon cleared out as the fire pushed through the chaparral. Sable Ranch, the western movie ranch that had hosted decades of film and television production in the valley, burned to the ground.
The Sand Fire was contained on August 3, 2016. It remains the anchor event in Santa Clarita's modern fire memory: proof that the canyons that define the city's east side can carry a major fire to its doorsteps.
The Tick Fire: the night Canyon Country emptied
The Tick Fire ignited near Tick Canyon Road on the afternoon of October 24, 2019, in a hard Santa Ana wind event. It grew by hundreds of acres within its first hour, jumped Highway 14, and burned against Canyon Country's neighborhood edges.
At 4,615 acres it was a fraction of the Sand Fire's size, and it still destroyed 22 structures and forced roughly 40,000 people to evacuate the Santa Clarita Valley. That is the modern fire lesson in one event: in wind, a small fire against a city edge is more dangerous to homes than a big fire in remote country.
Between the two, the December 2017 Rye Fire closed I-5 and threatened the Valencia side of the valley during the same wind siege that drove the Thomas Fire in Ventura County. West side, east side: the valley's exposure runs both directions.
Placerita Canyon's nature preserve, the oak woodlands around William S. Hart Park, and the open ridges above Saugus are why people live here. Zone Zero is how the homes and the landscape coexist.
Zone 0 and the 2025 hazard maps
In March 2025, CAL FIRE released updated Fire Hazard Severity Zone maps that expanded the Very High zones across the Santa Clarita Valley compared to the maps drawn more than a decade earlier. The Los Angeles County Fire Department adopts and enforces those maps locally.
If your street backs open space anywhere from Sand Canyon to Newhall Pass, check your parcel rather than assuming. The ember-resistant zone follows the map, and the map moved.
Fire history questions, answered
How big was the Sand Fire?
The July 2016 Sand Fire burned more than 41,000 acres along Santa Clarita's eastern edge, destroyed 18 homes, and killed two people. Roughly 10,000 homes were placed under evacuation, including Sand Canyon and Placerita Canyon.
What made the Tick Fire so dangerous at only 4,615 acres?
Speed and position. Driven by Santa Ana winds, it grew by hundreds of acres in its first hour, jumped Highway 14, and burned directly against Canyon Country neighborhoods. It destroyed 22 structures and pushed roughly 40,000 people out of the valley overnight.
Has fire ever reached the west side of the city?
Yes. The December 2017 Rye Fire started near the I-5 corridor during the same wind siege that drove the Thomas Fire, closing the freeway and threatening the Valencia side of the valley before crews caught it.
What do these fires have to do with a 5-foot rule?
Post-fire investigations across California kept finding the same thing: homes ignited by embers landing in the first few feet, in mulch, fences, and stored items, not by the fire front itself. Zone 0 exists because of that pattern, and Santa Clarita's fires fit it.
