Firefighters with CAL FIRE CZU announced Tuesday evening that they had stopped igniting new ground at Locatelli Ranch near Boulder Creek, wrapping up a day-long prescribed burn even as crews stayed put to watch remaining flames smolder across the property. Winds were blowing westerly, temperatures hovered in the low to mid 70s with a brief spike to 78 degrees at 1:30 p.m. before settling back to 74, and officials said some flames were still on the ground and being actively monitored.
The operation was planned as a single-day prescribed fire covering an estimated 42 acres at Locatelli Ranch in Santa Cruz County near Boulder Creek and the end of Empire Grade, according to the Monterey Bay Air Resources District. In its update posted to social media, CAL FIRE CZU
reported that firefighting crews were done putting fire on the ground for the day, while flames continued to flicker in patches that ground personnel were keeping an eye on. The agency's post also referenced a fire whirl during the operation and used the hashtag #CAWx to flag the update for weather watchers.
Mop-Up and a Public Eye on the Fire
Firefighters remained on scene following ignition to perform mop-up and patrol remaining flames, and the public could watch conditions unfold in near real time through the Eagle Rock Lookout 2 camera on the ALERTCalifornia network, per the air district's report. That kind of live visibility has become a routine feature of CAL FIRE CZU's prescribed fire operations, letting nearby residents check conditions for themselves rather than relying solely on official updates.
Eagle Rock Lookout itself sits near Locatelli Ranch at the northern end of Empire Grade, according to Eagle Rock - forest lookouts. The lookout's location near this stretch of mountain terrain adds a layer of continuity to Tuesday's burn.
Why Crews Are Burning This Particular Ground
Santa Cruz County Vegetation Management Forester Scott Bullock said the burn was designed to clear encroaching brush and preserve oak-woodland and grassland habitats, ecosystems the air district reports are declining statewide due to development pressures and a shrinking number of working ranches. That framing casts the Locatelli Ranch project as more than routine fuel reduction — it's also aimed at protecting a type of landscape that has become increasingly rare across California.
Prescribed burns like this one are tightly regulated. Projects in the Santa Cruz Mountains must comply with Monterey Bay Air Resources District Rule 438 and California Title 17 guidelines, which require mandatory permissive burn days and favorable wind windows to ensure smoke disperses properly rather than settling over nearby communities. Those requirements govern when burns can take place. Tuesday's burn occurred amid steady westerly wind and moderate temperatures.
Burning Inside a Familiar Scar
Locatelli Ranch sits directly inside the burn scar of the 2020 CZU August Lightning Complex Fire, which scorched more than 86,500 acres across San Mateo and Santa Cruz counties and destroyed 911 homes, according to the San Lorenzo Valley Post. That history helps explain why local communities like Boulder Creek and Bonny Doon watch these controlled burns so closely, even when the fire is intentional and supervised.
Tuesday's ignition took place at Locatelli Ranch. The agency has carried out other fuel-reduction work across its jurisdiction, including a burn near San Andreas Dam, the San Andreas Dam burnout among them.
Ground Crews Built for Steep Terrain
Following Tuesday's ignition, firefighters remained on scene for patrol and mop-up work.
Residents can use CruzAware for prescribed-burn notifications. With flames still smoldering on the ground at Locatelli Ranch as of Tuesday evening, crews are expected to keep watch until conditions are fully secured.
