Wildland Urban Interface

---

The Wildland Urban Interface (WUI) represents the boundary between unoccupied land and human development, where structures and human activity interface with natural wildland or vegetative fuels. This transition zone can vary from a distinct line to a broader area where development and natural landscapes converge.

In areas of the WUI where buildings lack access to fire hydrants or immediate local fire department response, compliance with Fire Codes and local jurisdiction requirements mandates the development of a specific fire protection plan. This plan must address various strategies, such as building compartmentalization with self-closing fire doors and rated walls to limit potential interior fire spread. Additionally, on-site water storage tanks are often installed to ensure responding fire departments have adequate firefighting capabilities. Exposure protection systems are also employed to minimize heat transfer from wildfires to buildings, further safeguarding structures.

These measures are essential for mitigating fire risks in vulnerable areas where human development and natural landscapes intersect, ensuring the safety and resilience of communities in the Wildland Urban Interface.
