Which Areas Are Most at Risk for Wildfires?

Each year, wildfires take lives and burn countless structures, resulting in mounting costs that have enormous economic and environmental impacts on communities and businesses. The Fireline Wildfire Risk Analysis identified 45,152,000 properties, located in the 13 western states, at high to extreme risk of wildfire. California has the most homes located within the WUI, followed by Texas, Florida, North Carolina and Pennsylvania. Wildfires also have devastating impacts on the environment and damage forests, rangelands, watersheds and wildlife.

A total of 5,972 structures were reported destroyed by wildfires in 2021, including 3,577 residences, 2,225 minor structures, and 237 commercial/mixed residential structures.

As the wildland urban interface grows and the risk of fire in these areas increases, communities must be prepared to implement strategies that enhance their resilience, including adhering to fire resistant construction standards.

How Communities Can Mitigate Wildfire Risk

To mitigate their risk to wildfires, communities must develop and update Community Wildfire Protection Plans to ensure the planning and implementation of resilience construction and landscapes. The new U.S. Department of Agriculture (USDA) Forest Service Cohesive Wildland Fire Management Strategy RFA 2022 will make available roughly $5 million to support the goals of the National Cohesive Wildfire Management Strategy, including development and implementation of Community Wildfire Protection Plans.

There is also funding available to support wildfire protection planning and mitigation projects through the FEMA grant programs. Engagement of wildfire planning, through Wildfire Protection Plans, should be coordinated at the community level, not just the neighborhood level to ensure safe and effective wildfire response.

Wildland-Urban Interface Codes Support Communitiy Resilience report

The adoption and enforcement of building codes – particularly the International Wildland Urban Interface Code – is one method to mitigate the impacts of wildfires and enhance resilience.

2021 International Wildland-Urban Interface Code

Building codes are an essential strategy in mitigating risk and achieving resilience. The effective adoption, implementation and enforcement of building codes, particularly the International Wildland-Urban Interface Code (IWUIC), supports the goal of making homes and other buildings more resistant to ignition.

Retrofitting structures to the Code Council’s Wildland-Urban Interface Code could provide $2 to as much as $8 in mitigation benefits for each $1 invested. The IWUIC addresses the specific risks to people and structures in the WUI, providing solutions to manage vegetation and fuels, protecting homes, communities, and other systems at risk.
