Design Matters: Fire Safe Design in Land Planning

As development continues to expand into Utah’s Wildland-Urban Interface (WUI), wildfire resilience is becoming an increasingly important consideration in the land planning . While wildfire mitigation is often associated with emergency response or building materials, many of the most impactful decisions happen long before construction begins.

For Bryan Wilson, Project Manager in FOCUS’s Land Planning department, fire-safe design starts with understanding how a community’s layout, landscape, and surrounding environment influence wildfire behavior. He explains that fire-safe design is the intentional planning of buildings, landscapes, roads, open spaces, and vegetation to reduce wildfire exposure and the potential for structure ignition.

Beyond the Flames

When evaluating wildfire risk, it is important to look beyond the flames. According to Bryan, embers are often one of the greatest threats to structures because they can travel significant distances and ignite vegetation, mulch, decks, fences, and other combustible materials throughout a neighborhood. As Bryan explains, “Fire-safe design needs to consider not only the wildfire itself, but also what happens when thousands of embers land throughout a neighborhood.”

Planning for Resilience

Effective wildfire mitigation begins during site planning. Evaluating existing vegetation, slopes, drainage patterns, prevailing winds, and adjacent fuel sources helps project teams make informed decisions about where development should occur. Community layout can also reduce risk. Roads, trails, parks, irrigated open spaces, and strategically managed landscape areas can help interrupt continuous fuel sources while enhancing the character and function of a development. Bryan notes that wildfire preparedness is most successful when planners, engineers, landscape architects, municipalities, and fire agencies work together early on and throughout the design process.

Designing the Landscape

Landscape architecture contributes far more to wildfire resilience than plant selection alone. Plant spacing, irrigation, maintenance, fuel separation, mulch selection, and tree placement all influence how a landscape responds during a wildfire event. A common misconception is that fire-safe landscapes must be sparse or unattractive. Bryan believes “the most effective fire-safe landscape isn’t necessarily a barren landscape. It’s a thoughtfully designed landscape that manages fuel continuity, protects the structure’s immediate surroundings, respects topography, provides emergency access, uses appropriate vegetation, and can actually be maintained over time.”

Thinking Long Term

One of the most common mistakes Bryan sees in fire-prone areas is treating wildfire mitigation as an afterthought. Continuous walls of vegetation, inadequate emergency access, poor maintenance planning, and failing to consider surrounding properties can all increase long-term risk. Ultimately, wildfire resilience is not achieved through a single design feature. As Bryan puts it, “Good landscape design isn’t just about how a community looks today. It’s about how that landscape performs when conditions are at their worst.” By incorporating fire-safe design principles early, communities can become better prepared for the realities of growth in Utah’s WUI areas.
