Growing fire threat puts Sonoma County’s wooded towns on high alert
Standing on the south slope of Healdsburg’s Fitch Mountain, Cal Fire Battalion Chief Marshall Turbeville surveyed a distressing scene.
Above him, a towering fir tree was close enough to fall across two roads, blocking access and bringing down power lines that could remain live and dangerous on the ground. To one side, the roof and gutters of a residential structure were full of leaves ready to ignite from a windblown wildfire ember in dry weather.
On the way up Spring Street, Turbeville’s four-wheel drive pickup had met a descending UPS truck, forcing him to pull off the substandard, single-lane road. In an emergency, fire engines and evacuating residents could be at a similar standoff.
“When you think about everything that needs to be done to make this place safe, it’s mind-boggling,” said Turbeville, a 24-year veteran with the state firefighting agency.
Fitch Mountain, a tree-covered, 990-foot-high point on a bend in the Russian River, is an idyllic rural area, teeming with wildlife and screened off from urban noise and lights.
It is also a Cal Fire-designated high fire-risk zone, abounding with potential to erupt in flames threatening the lives and property of residents in about 340 homes.
“Wind from any direction could fan an ignition source,” states the Fitch Mountain Park and Open Space Preserve Management Plan. “Steep slopes all around can allow for the uphill thermal rush of flames through areas of continuous fuels from ground to treetop.”
And Fitch Mountain is just one of 40 Sonoma County “communities at risk” cited in a Fire Management Plan for Cal Fire’s Sonoma-Lake-Napa Unit. Across the three-county region more than 70 populated areas are at risk.
The list includes areas around the cities of Santa Rosa, Rohnert Park, Windsor, Cloverdale, Sonoma and Petaluma, as well as the smaller communities of Camp Meeker, Bodega, Glen Ellen, Kenwood, Bennett Valley, Valley Ford and Boyes Hot Springs.
The 1,576-square-mile county, bludgeoned by the firestorms of 2017 that killed 24 people, destroyed 5,334 homes and did about $9 billion in insured property damage, is an ideal breeding ground for such conflagrations, experts say.
Wildland fire behavior depends on three primary factors - fuels, topography and weather - and Sonoma County has all three conducive to big burns. The same holds true for neighboring Napa and Mendocino counties, and Lake County, where wildfires since 2015 have burned more than half of the territory.
Climate change is stoking the risk, according to experts, with rising average temperatures that can make fire seasons longer and more severe.
More than half of Sonoma County has been rated by Cal Fire as moderate or high fire hazard risk, with very high hazard zones in the mountainous eastern range, along the coast north of Salt Point State Park and in small pockets in west county and around Lake Sonoma.
The upshot, Turbeville said, is ominous: “Every square inch of California can burn. It’s just how bad or how often or how soon.”
No one knows what 2019 will bring, but there have already been 14 major wildfires reported by Cal Fire from Siskiyou to San Diego counties.
In some fire-prone Sonoma County communities, residents are well aware of the situation.
“There’s just a ton of risk up here,” said Priscilla Abercrombie, a Fitch Mountain resident for seven years.
During the 2017 firestorm, cellphone, WiFi and landline service on the mountain went down, leaving residents with only radio for information, she said. No fires came close, but it reminded Abercrombie that evacuation could easily be compromised with just one road going around the back side of the mountain and a web of one-lane roads on the slopes that could easily get jammed.
If a fire started along South Fitch Mountain Road, it could threaten ?10 to 15 homes in the first half hour, Turbeville said. Evacuation would be Cal Fire’s top priority and residents should be prepared to walk out, if necessary, he said.
The mountain’s Citizens Organized to Prepare for Emergencies group, known as COPE, held a training session May 17 with Turbeville and Don McEnhill, executive director of the nonprofit Russian Riverkeeper group. The session focused on using the river as a community refuge area in the event of wildfire.
The “homework assignment,” Abercrombie, the group’s co-leader, said, was for residents to plot a way to reach the river in the dark. The best option would be a large gravel bar, while going into the water would be a “last choice.”
Residents along the river could consider posting signs at the access points, she said.
Turbeville said in an interview that the manicured green Healdsburg Golf Club on the mountain’s west flank would be a more suitable community refuge.
