UCSB WRI

Stay ahead of wildfire risk with the UCSB WRI app — an interactive mapping tool built for residents, fire agencies, and planners in Santa Barbara County. Developed by the UC Santa Barbara Wildfire Resilience Initiative, the app delivers critical spatial insights to support wildfire preparedness and informed decision-making. Explore a rich set of data layers covering key wildfire risk factors: • Hydrant-Structure Access — Assess the unobstructed shortest paths to the furthest, least-accessible points of buildings from nearby hydrants or access roads • Hydrant Spacing — Pinpoint areas where hydrant spacing may be insufficient for effective firefighting • Road-Hydrant Proximity — See which hydrant is closest to any road segment and how far road sections are from hydrants • Evacuation Potential — Assess which neighborhoods face higher congestion risk during an emergency evacuation • Live Fuel Moisture — Track recent vegetation dryness / fire ignition risk • Carbon Density — Locate high fuel load areas prone to more intense, harder-to-control fires • Fire Potential Index — See where high fire potential conditions occur most frequently in the past by month • Extreme Weather — Identify areas with recurring high winds or low humidity by month and time of day Download vector data for offline use when you're in the field without network connectivity. Save your preferred map styles, filters, and positions so the app reopens exactly where you left off.
