Understanding Disaster Declaration Thresholds

Chart of FEMA's threshold grid

The process of declaring a disaster involves meeting specific financial thresholds set by both the county and the state, which determine whether federal aid can be requested from FEMA.
  • Washoe County Threshold: $2,237,863.20
  • State of Nevada Threshold: $5,712,489.76
To be eligible for federal reimbursement, Washoe County must meet its threshold of $2,237,863.20. The State of Nevada must also meet its statewide threshold of $5,712,489.76 before FEMA assistance can be requested. Unfortunately, for this incident, neither Washoe County nor the State of Nevada met these thresholds, which is why we could not apply for federal disaster assistance at this time.

However, Washoe County engaged the Voluntary Organizations Active in Disaster (VOAD) to assist with unmet needs in the community. If you have specific needs, please contact Washoe311, and our staff will do our best to connect you with the appropriate resources.

 

Our Response

Washoe County has consistently maintained a strong policy and response to both flooding and flash flooding over the past decade. In June and July 2015, our community faced several isolated flash flood events that overwhelmed the stormwater systems, resulting in damage that was very similar to what we've recently experienced in Hidden Valley - damaged landscaping, heavy debris deposits, and impacts to home interiors. Additionally, in 2017, our area suffered two federally declared flooding disasters, causing significant damage to both infrastructure and private property. Throughout these events, our response has always prioritized life safety, ensuring access for emergency responders, and protecting property.

In Hidden Valley, our Roads crew responded immediately after the storm. The initial focus was on ensuring the safety of residents and emergency responders. Debris removal on the roadways began without delay, and by mid-day on July 22, all roads were cleared and accessible to emergency vehicles. Our crews used backhoes and motor graders to clear larger debris, while kick-brooms, water trucks, and street sweepers tackled the finer sediment. It’s important to note that our street sweeping activities are conducted in compliance with air and water quality requirements.

To further protect private properties, Washoe County Roads and Engineering staff promptly inspected the drainage infrastructure. They developed and implemented a plan to repair and re-establish critical areas. This work began immediately following debris removal and has been carried out by both County crews and contractors. We’ve also partnered with organizations like the Red Cross and Team Rubicon to provide additional support and assessment of damage to homes.

Stormwater is a natural and ongoing part of our landscape, and our stormwater infrastructure is designed according to Washoe County’s Development Code. These systems are built to manage runoff from minor, everyday storm events. For more detailed information on drainage and flooding, please visit the Washoe County Community Services Department (CSD).
