Box Elder County declared an emergency Feb. 14, and Cache County followed suit Feb. 15.
Gov. Gary Herbert requested the federal major-disaster declaration April 7, after various state entities responded to the flooding.
The National Guard was called out to help fill sandbags, and the Utah Department of Transportation responded to road damage and mudslides. The Utah Highway Patrol closed highways and roads while UDOT and area officials cleared debris. The Utah Geological Survey monitored landslides and relayed information to officials about risks and vulnerabilities.
Before and between two major winter storms, the temperature climbed 10 to 15 degrees warmer than the 30-year average, causing the snowmelt, McInerney said. The temperature Feb. 11 was 21 degrees higher than the 30-year average, he said.
“It’s pretty radical weather, when you look at it,” McInerney said.
The state requested $5.9 million — $3.2 million for Box Elder and $2.7 million for Cache County — and that amount may be adjusted as damage is assessed by federal officials.
The federal funding will help repair publicly owned infrastructure, such as roads and bridges, and reimburse debris-removal costs, said Joe Dougherty, spokesman for the state Division of Emergency Management.
The money also will be allocated to hazard mitigation — projects that make existing infrastructure stronger to prevent future flooding — which the state will prioritize.
