Folsom Fire Department personnel helped manage the 622-acre Floriston Fire near Truckee during a weeklong deployment. The team joined the Sacramento Regional Incident Management Team, which assumed command of the fire at 7 a.m. Thursday, Sept. 17, and transitioned control back to local agencies at 7 a.m. Tuesday, Sept. 22, according to CAL FIRE's incident page.

The department said its members served in roles spanning Incident Command, Logistics, Operations, Planning and Safety, according to Folsom Times.

The Floriston Fire ignited at about 10:01 a.m. Wednesday, Sept. 16, near Interstate 80 and Floriston Way, roughly nine miles northeast of Truckee in the Truckee River Canyon. CAL FIRE initially reported the blaze at about 20 acres with a dangerous rate of spread. Strong winds pushed it east, and crews reported long-range spotting. The fire grew to nearly 300 acres within hours.

Westbound Interstate 80 was closed at the Nevada state line during the early stages. Evacuation orders and warnings went out in Nevada and Sierra counties.

By Friday, Sept. 18, the response had swelled to 1,579 personnel with 107 engines, 51 hand crews, 18 helicopters, 14 bulldozers and 16 water tenders, CAL FIRE reported. Staffing peaked at 1,613 on the morning of Saturday, Sept. 19. The Union Pacific Railroad Fire Train provided 100,000 gallons of water to support firefighting operations, according to CAL FIRE.

The regional team draws from Sacramento Metropolitan Fire District, Sacramento Fire Department, CAL FIRE and agencies in Amador and El Dorado counties, among others, KCRA first reported. Floriston Incident Management spokesperson Chris Vestal told KCRA on Sept. 17 that the team was preparing for an extended stay. "We'll be out there for probably at least a week," Vestal said.

As of CAL FIRE's Tuesday, Sept. 22, evening update, the fire stood at 622 acres and 96% containment, according to Folsom Times. One CAL FIRE incident page entry listed 95%. All evacuation warnings had been lifted, and both westbound lanes of I-80 were open, though the Farad exit remained closed. No structures were destroyed or damaged, and no injuries or fatalities were reported. The cause remains under investigation.

The deployment also brought an unexpected moment. Susan Bower of Creekside Charter School, a K–8 school in Olympic Valley near the fire zone, delivered handwritten thank-you cards from students to Folsom Fire members on the assignment.

Crews remained in the fire area as of Wednesday, Sept. 23, to secure containment lines. A forest closure stayed in effect to protect personnel still working the scene, according to 2 News. CAL FIRE reported 1,175 personnel still assigned, including 62 engines, 34 hand crews, eight helicopters, 25 water tenders and three bulldozers.
