CAL FIRE urges Bay Area defensible space

CAL FIRE and local Bay Area fire officials are pushing a simple message at the start of June: cut back vegetation before smoke or an inspection notice forces the issue. The warning comes as California’s 2026 fire season accelerates and as state officials point to drying fuels, early fire activity and rapidly melting Sierra snowpack. In Bay Area interviews published over the weekend, officials said homeowners should create defensible space now, especially in neighborhoods where homes sit close to open space or steep, brushy terrain. CAL FIRE’s own guidance says defensible space is the first line of defense for a home in wildfire. ### Why are Bay Area officials talking about this now? Saturday, May 30, brought one of the clearest local warnings so far, when ABC7 San Francisco reported that CAL FIRE and regional officials were urging Bay Area residents to create defensible space as wildfire season begins. CAL FIRE Battalion Chief Brent Pascua told the station that early snowpack melt and record heat in March had extended the peak fire season. (abc7news.com) CAL FIRE’s 2026 incident archive says Northern California saw a sharp rise in daily fires during May, while statewide fire activity was already trending above normal. The agency said the north Sierra snowpack fell from roughly 75% to 80% of normal on May 1 to 20% to 30% by the end of the month. ### What exactly does “defensible space” mean? CAL FIRE defines defensible space as the buffer between a structure and the surrounding area. (abc7news.com) The agency says that buffer helps slow or stop fire spread and gives firefighters a safer area to defend a property. State guidance breaks that buffer into zones. CAL FIRE says the first five feet around a home — Zone 0 — is the most important area because embers can ignite material close to walls, decks and attached fencing. (fire.ca.gov) From five to 30 feet, the state advises residents to keep vegetation lean and well spaced. From 30 to 100 feet, or to the property line if closer, residents are told to continue reducing fuel. (fire.ca.gov) ### What are officials asking homeowners to do right away? David Glenn of the Marin Wildfire Prevention Authority told ABC7 that fire departments would rather residents trim vegetation on their own than force compliance. “They’d rather that people take it upon themselves to cut the vegetation back,” Glenn said. (fire.ca.gov) CAL FIRE’s checklist is specific. The agency says residents should remove dead plants, weeds and debris from roofs, gutters, decks and the ground immediately around the house; avoid combustible mulch in the first five feet; keep branches separated; and maintain clearance around outbuildings, propane tanks and wood piles. ### Is this voluntary advice or a legal requirement? (abc7news.com) California law already requires 100 feet of defensible space in applicable areas, according to CAL FIRE’s public guidance and the Board of Forestry and Fire Protection. The Board says owners in State Responsibility Areas and in Very High Fire Hazard Severity Zones in local responsibility areas are responsible for complying with defensible-space requirements. (fire.ca.gov) The Board also says Zone 0 rulemaking was ordered under changes to Public Resources Code 4291 and related state action. That has put added attention on the first five feet around homes, even as broader 100-foot clearance rules remain in place. ### How does the Grass Valley air base fit into this? YubaNet reported on June 1 that CAL FIRE’s Tanker 88 and Air Attack 230 arrived at the Grass Valley Air Attack Base from McClellan to begin 2026 fire season operations. (fire.ca.gov) The move coincides with the broader statewide ramp-up in staffing and aircraft positioning. CAL FIRE says its aviation program includes nearly 70 fixed- and rotary-wing aircraft positioned across one airtanker base, 13 air attack bases and 10 helitack bases. (bof.fire.ca.gov) The agency says that network is intended to reach remote State Responsibility Area fires in about 20 minutes and support its goal of containing 95% of fires to 10 acres or less.

The Board of Forestry and Fire Protection is also continuing work tied to Zone 0 standards, while local Bay Area agencies are expected to keep pressing property owners in high-risk neighborhoods to clear vegetation before hotter, drier conditions arrive later this summer.
