$CITR San Diego has already given this story something early-stage names rarely get: public, field-level validation
On January 30, 2025, the city said Fire-Rescue crews were spraying the treatment in high-risk areas, along evacuation routes, and near previously cleared encampments. Fire Marshal Tony Tosca said the program identified 46 acres for treatment, focused on zones 10 feet from roadways in communities with only one evacuation route. The project was backed by a
$366,949 grant and tracked with GPS/ArcGIS for monitoring
Then the follow-through got more interesting. In the Montezuma/Fairmount evacuation corridor, near Alvarado Estates, Assistant Fire Marshal Alex Kane said documented fires fell from 10 in 2024 to 7 in 2025 over the same January-November period, a 30% reduction. That is not lab theory. That is city-linked field data from an active mitigation zone
