Fire departments and law enforcement agencies across the Spokane region are absorbing sharply higher operating costs this year as diesel fuel prices climb toward $6.35 per gallon, straining budgets and complicating long-range financial planning for agencies that cannot simply park their trucks.
The pricing pressure has real dollar consequences. The Spokane Fire Department projects it will spend roughly $100,000 more on fuel in 2026 than originally budgeted, driven by a fleet that covers an average of 600 miles per day. Each fire engine holds between 40 and 50 gallons of diesel, and at current pump prices the department is absorbing approximately $340 in extra daily fuel costs across its largest apparatus alone.
Every Gallon Costs More — Even When Volume Stays the Same
The numbers from Spokane Valley Fire illustrate just how dramatically the price spike is outpacing actual consumption changes. Between March and May 2026, the department used just one additional gallon of diesel compared with the same three-month stretch in 2025 — yet its fuel bill came in $25,408 higher. The increase was almost entirely a function of price, not use.
The Spokane Police Department entered 2026 already spending close to $70,000 per month on fuel. When diesel prices surged in March, the department paid approximately $23,000 more that month alone. The city had allocated roughly $1 million toward police fuel for the full year, a figure that appeared adequate in January but has since come under pressure.
Spokane Fire Department spokesman Justin de Ruyter said the pricing environment is creating downstream problems beyond the immediate budget hit. “It affects long-term planning,” he said. “Compounded with frequent budget cuts or threat of cuts, it increases the complexity for our chiefs to forecast our expenses.”
Smaller Districts Feel the Pressure More Acutely
Smaller fire districts operating on tighter margins are finding the price environment particularly challenging. Spokane County Fire District 4 spent approximately $10,894 on fuel in the same period a year ago; this year that figure has grown by roughly $9,000, a proportionally significant increase for a smaller operation.
Spokane County Fire District 3 offers perhaps the clearest picture of what climbing prices mean over a full budget cycle. The district spent $121,455 on fuel in all of last year and set its 2026 fuel budget at $130,000 — a figure that already reflects an anticipated increase. Through the first four months of 2026, District 3 averaged $8,780 per month on fuel, then saw May jump to $12,689 as prices escalated. The district’s heavier spending months are still ahead: last year it paid $14,754 in August, $12,180 in September, and $16,352 in October as fire season drove up vehicle use.
District 3 representative Cody Rohrbach said the nature of firefighting equipment makes fuel a uniquely unavoidable expense. “For us, how we get around and the size of our vehicles, gas prices are significant,” Rohrbach said, noting that the agency cannot downsize its apparatus or reduce response miles to cut costs.
The challenge facing all of these agencies is structural: emergency response vehicles must respond regardless of fuel prices, and the fleet compositions are dictated by public safety requirements rather than economic efficiency. Unlike a private business that might reduce vehicle trips or renegotiate delivery schedules, a fire department runs the same routes on the same schedules whether diesel costs $3 or $6 a gallon.
What Comes Next
Fire officials are watching the summer months with particular concern. August, September, and October historically represent the peak of wildfire season in the Inland Northwest, meaning fuel consumption — and therefore costs — typically spike precisely when prices remain elevated. District 3’s budget of $130,000 for the full year may face a serious stress test before October is over if prices hold near current levels and fire activity demands extended operations.
For municipal and county budget officers, the sustained high diesel environment is also likely to surface in mid-year budget reviews. Agencies that locked in fuel allocations during annual budget cycles now face the prospect of returning to governing boards for supplemental appropriations — adding another layer of fiscal pressure to departments that are already managing constrained resources. Residents and taxpayers across the Lewis-Clark Valley and broader region may see similar patterns play out in local agency budgets as the fire season approaches.
