Fire Factor by Risk Factor™: Calculating Fire Risk on Your Street

Warm, dry summertime weather is ideal for building houses, but these conditions can increase the likelihood of wildfires. As you may expect, California was ranked as the top wildfire-prone state in 2021 (2,233,666 acres burned), but the devastation of wildfires is also felt in mixed-humid areas like Missouri (40,262 acres burned), North Carolina (25,838 acres burned) and Mississippi (21,037 acres burned). 

To offer greater support across the U.S., LP Structural Solutions is partnering with the First Street Foundation, which helps builders assess and protect against environmental threats from fire, flooding and wind. Let’s dive into the First Street risks for fire and learn how to build for greater resiliency when the risk of fire is high. 

What is Risk Factor From First Street?

Risk Factor® is an online assessment tool that makes it easy for builders and homeowners to understand environmental threats at an address level and to learn how risks can change with changing environmental threats.

What’s different about this tool is that builders and homeowners enter a home’s specific address to review current and future risks of a changing climate. You may not expect that a home in Missouri, for example, may be affected by wildfire, but if Risk Factor specifies that the fire risk for that address is high, the builder can take steps to mitigate those specific risks. 

How Fire Factor by Risk Factor® Calculates Risks 

The Fire Factor tool considers the vulnerability of the property’s building materials, distance to fire risk areas and potential burnable materials, like vegetation, to determine the risk of being impacted by wildfire, assigning the address a score ranging from 1 (minimal) to 10 (extreme). 

An Integrated Approach to Fire Risk

When the risk from a potential wildfire is high, builders can consider incorporating preventative measures into the structure to help slow the spread of fire.

“If you’re building in an area prone to wildfires, it’s good practice to go beyond the minimum building code to add additional resilience in the structure,” says Scott Johnson, Construction Services Manager at LP.
