This edition of Zoning Practice is available free to all.

From wine country in California to suburban homes in Colorado to small towns in Tennessee, large wildfires threatening homes and communities are in the headlines more often than ever. As development increasingly spreads into areas that border or commingle with forests, grasslands, and other open spaces — an area known as the wildland-urban interface, or WUI — more communities are taking steps to proactively address the risks associated with wildfire.

This edition of Zoning Practice discusses how key characteristics of development in the WUI influence wildfire risk, and it highlights a range of land-use and development regulations that affect the extent, design, and ultimate safety of WUI development. These regulatory tools include zoning overlays, transfer of development rights, WUI codes, subdivision controls, defensible space regulations, landscaping standards, use-specific standards, and code enforcement.
