A grass fire broke out Tuesday, Aug. 4, between Tanner Park and Interstate 215, marking the third time in less than a month that the wind-prone corridor at the mouth of Parleys Canyon has ignited.

The fire came less than 24 hours after the 15-acre "Millcreek Fire" was declared out Monday evening. KUTV reported the new blaze Tuesday night, raising fresh concerns about wildfire risk in the area. Specific details about the Aug. 4 fire's size, cause and outcome have not been confirmed by Unified Fire Authority.

The corridor has now burned three times since mid-July, when a 1-acre grass fire near Tanner Park drew an aggressive initial attack from firefighters. Monday's larger fire forced closure of the eastbound I-80 to southbound I-215 ramp and southbound Foothill Drive, threatened homes in the Canyon Rim neighborhood and drew helicopters and air tankers from Idaho that used Canyon Rim Elementary School as a water-drop dip site. Unified Fire Authority declared that fire out by about 7:45 p.m., with no evacuations or structure losses, as we reported Aug. 4.

UFA spokesperson Nate Cochran told Fox 13 during coverage of the Aug. 3 fire that the burn scar from the mid-July blaze actually helped crews fight Monday's fire, and that the network of trails in the area acted as small fire breaks.

Residents along Louise Street, which sits adjacent to the fire corridor, say the recurring fires have become an unsettling pattern. Julie Naeth, a Louise Street resident, told ABC4 on Aug. 3 that the street's notorious wind gusts could push flames into the neighborhood quickly. As we reported that same day, the wind corridor has long worried Canyon Rim homeowners.

"We jokingly call it 'hurricane Louise' which is the street that I live on," Naeth told ABC4 on Aug. 3. "If the wind shifts, it can change things pretty dramatically in this neighborhood."

Naeth also told ABC4 that neighbors have gathered on the street to watch smoke rise on multiple occasions, calling it a strange form of neighborhood bonding tempered by relief that flames have not yet reached homes.

The fires come during Utah's record-breaking 2026 wildfire season, which prompted UFA to deploy crews to Oregon in late July for a 14-day mutual-aid assignment, as we reported July 29.

The cause of all three fires remains under investigation. Residents can report fire hazards or suspicious activity to Unified Fire Authority or call 911 for active fires.
