The canyon that learned the hard way.
In September 2017, 7,194 acres of the Verdugo Mountains burned in the La Tuna Fire — the largest wildfire in the City of Los Angeles in fifty years. Five months later, rain on the denuded hillsides sent 36-inch debris flows down La Tuna Canyon Road. Those nine days of fire and the winter that followed reshaped how canyon residents think about readiness.
Why the canyon is at higher risk
La Tuna Canyon sits inside a Very High Fire Hazard Severity Zone as mapped by CAL FIRE. The combination of factors is, by now, a textbook California wildfire setup: steep slopes, aged chaparral, Santa Ana wind corridors running down from the high desert, dry summers that extend later and later into the year, and a road network with limited redundancy. The 2017 La Tuna Fire ignited in a drainage on the 10800 block of La Tuna Canyon Road and was in four separate sectors of the Verdugos within hours.
This is not abstract. For residents, it means a meaningful portion of the year — typically June through the first heavy winter rain — requires operational readiness, not just awareness.
The canyon preparedness checklist
A working minimum. None of this is exotic. All of it is worth doing before you need it.
Alerts and information
Sign up for LA County emergency alerts at lacounty.gov/alert. Add NotifyLA (City of LA) at emergency.lacity.gov/notifyla. Both push evacuation orders and red-flag warnings directly to your phone — the only reliable way to know when a specific block is under order.
Defensible space
Zone 0 (0–5 ft from structure): no combustibles — no bark mulch, no firewood piles, no dry plants. Ember-resistant materials only.
Zone 1 (5–30 ft): irrigated plants, spaced apart; no ladder fuels (tall grass or shrubs connecting ground to canopy); clear roof gutters seasonally.
Zone 2 (30–100 ft): grass mowed to 4 inches, tree canopies thinned, deadwood removed. LAFD inspectors check this zone annually in fire-hazard areas.
Go-bag
One bag per household member, ready by the door during fire season. Inside: three days of water and non-perishable food, essential medications (and a separate copy of prescriptions), N95 masks, phone charger and battery pack, flashlight, paper copies of insurance policies, IDs, a small stash of cash, a change of clothes, sturdy shoes.
Evacuation routes
Know at least two ways out of the canyon. La Tuna Canyon Road has limited through-capacity during a major event — in 2017, it closed in both directions on Day 1 of the fire. Alternate routes worth knowing: Sunland Boulevard (west end), Tujunga Canyon Boulevard and the 210 Freeway (east end), and the back-route via Shadow Hills to Foothill Boulevard. Drive them once, in daylight, before you need them.
Horses and large animals
Canyon residents with horses: have a trailer plan before fire season. If you don't own a trailer, establish a mutual-aid arrangement with a neighbor who does, or identify an evacuation service in advance. Hansen Dam Horse Park and the Los Angeles Equestrian Center (Griffith Park) have historically accepted evacuated horses during Valley fires.
Red-flag days
On any red-flag warning day: keep vehicles fueled and pointed out, bring go-bags into the main living area, close windows, charge phones, bring pets indoors, and monitor alerts actively. Santa Ana events in the Verdugos can push a small fire into a major event in under an hour.
Post-fire: the mudflow risk
After a major fire, the hillsides above the canyon pose a second, slower threat: debris flows. Hydrophobic soil produced by high-heat burns cannot absorb rainfall; storms that would normally infiltrate instead run off the surface, picking up ash, rocks, and burned vegetation. In January 2018, four months after the La Tuna Fire was declared contained, a winter storm sent a three-foot debris flow down La Tuna Canyon Road and into 40–45 homes along Country Club Drive in Burbank.
LA County Public Works issues Phase 2 debris flow forecasts for burned watersheds during major rain events. If you live in the impact box defined by Horse Haven Street (north), Martindale Avenue (east), Penrose Street (south), and Ledge Avenue (west) — and a Phase 2 forecast is in effect — plan to leave before the rain arrives, not during it. See the 2018 mudflows chapter for the full account.
Local responders and community resources
LAFD Fire Station 77, at 9224 Sunland Blvd in Sun Valley, is the nearest primary structural response. For wildland response in the Verdugos, LAFD coordinates with LA County Fire and CAL FIRE depending on incident size. The volunteer group La Tuna Canyon Fire & Rescue, formed after the 2017 fire, runs community readiness programs and neighborhood outreach — worth connecting with if you've just moved in.
"Don't take this lightly. The unpredictability of the way the slides occur is something we cannot control." — Councilwoman Monica Rodriguez, during the 2018 post-fire storms.
