My Husband, the Fire Ecologist in the News

My husband, fire ecologist and SF Chronicle columnist (Ask an Arborist, 1st Saturday of the month, plug plug) is quoted in this article on fire storms.


Wooded hillsides, narrow roads make Bay Area a 'disaster waiting to happen'
Kevin Fagan, Chronicle Staff Writer

Thursday, October 25, 2007

--------------------------------------------------------------------------------
The right combination of the wrong conditions could create a firestorm in the Bay Area every bit as devastating as the one savaging Southern California, fire experts say - and nowhere is that danger more acute than in sleepy Mill Valley.

There, sprinkled throughout the lushly forested slopes of Mount Tamalpais, lie some of the Bay Area's most expensive houses. The beauty is double-edged: The same verdant slopes that draw the wealthy and the famous also harbor heavy underbrush and trees that have not burned for nearly 80 years. And the narrow, twisting roads that give the town's neighborhoods their charm would turn into death traps with the first wreck during an evacuation.

All that is needed to light up this residential wonderland would be a couple of weeks of hot sun, a strong easterly wind and a spark of some kind, experts say.

With enough bad luck, it could happen next month, after the recent rains dry completely off.

"The fire conditions there and on the mountain in general are absolutely horrendous," said Ray Moritz, a Sausalito-based fire ecologist who advises fire departments all over the Bay Area. "The fuel load (potentially flammable wood) is tremendous. It's a disaster waiting to happen."

The Bay Area's other hot zones of high risk are not far behind.

Similar conditions - houses nestled in thick growth on hillsides with hard-to-negotiate, narrow roads - exist in parts of Contra Costa, Alameda and San Mateo counties. A lot of progress toward standardizing fire hydrant fittings, radio communications and construction requirements has been made all over the Bay Area in the past 15 years, but in those three areas in particular, there is still a lot of catching up to do.

To residents, such areas are just enclaves of fine houses in beautiful wooded settings. Fire experts call them wildland interface zones.

"A lot of the hills areas in Berkeley and Oakland, in and around where that awful 1991 Hills Fire happened, are still at great risk," said Contra Costa County Fire Protection District Chief Keith Richter, who coordinates mutual aid for fire departments from Oregon to Monterey. "On the other side of the hills, in parts of Orinda, Lafayette and Walnut Creek, conditions are also ripe."

He said road widths of at least 22 feet, allowing for fire engine movement even in a jam, have become common in new construction sites. But there are still a lot of old neighborhoods in the East Bay hills where the modern era has not caught up.

"Areas like the little community of Canyon, the south ends of Lafayette and Orinda - those are real hot spots for us," Richter said.

If a blaze began chewing up the dry brush and oaks of Contra Costa badly enough, Richter said, most fleeing residents would be sheltered at schools with fields that could act as firebreaks, such as Stanley Middle School in Lafayette. Concord Pavilion could house thousands in a pinch.

On the other side of the hills, schools like Oakland Technical High School were evacuation points in the 1991 blaze. Oakland's Coliseum could act as a gathering point if things got chaotic enough.

There are those who lived through the 1991 disaster who have no doubt chaos would happen.

"There are quite a few spots where the city hasn't been able to widen the roads, and on the ones that have been improved, we now often have a problem of too many cars," said David Kessler of Oakland, who lost his house in 1991 and heads the North Hills Phoenix Association of fire-conscious residents. He pointed to Charing Cross Road, where six people died in narrow roadways trying to flee the Hills Fire.

"And on Bristol and Buckingham roads, the city has allowed a lot of big houses, and people park where they shouldn't.

"What if someone is holding a big party along one of those roads when a fire breaks out? Nobody will be able to drive past the cars, and we'll have the same disaster we had all those years ago."

Fire ecologist Moritz said the same concerns can be found in the San Mateo County hills around Woodside, though the danger of fatalities is lessened by the sparseness of the population there. Vaca Mountain, east of Napa, is also considered by fire experts a potential tinderbox, though it too, is thinly populated.

But when fire planners gather to ponder how best to gird for the next big blaze, Moritz and his fellows always pull out the map of Mill Valley and its surrounding communities.

The last big fire there was in 1929, and it burned 1,000 acres and 115 homes. Since then, the population of the area and the size and value of the houses have soared.

The worst-case scenario, Moritz said, would involve a major earthquake during high fire season. Considering that the Bay Area is overdue for a major quake by at least a decade, by many seismic estimates, this is not out of the question. The region's most catastrophic quake in modern times, Loma Prieta in 1989, and the most catastrophic fire, 1991's Oakland Hills Fire, both happened in October.

"If you get a big quake and fires break out, it would be impossible to block the advance of the blazes around Mount Tam," Moritz said. "The roads would be blocked or damaged by the quake, services cut off, emergency personnel overwhelmed handling the quake. Very quickly, the fires could get so powerful that dumping retardant on them with helicopters and airplanes would be like spitting on them."

That was the scenario in the 1991 Hills Fire, which turned 2,900 homes to ash and killed 25 people. The same thing happened in Marin County's worst fire, the Mount Vision Fire, in 1995. It roared out of control near Tomales Bay State Park for a week, destroying 12,350 acres, forcing 500 people to evacuate and destroying 45 homes. It's what's happening now in Southern California.

Mill Valley's 13,600 residents are particularly vulnerable to such a fire because the town is situated among canyons and arroyos that would turn into blowtorches in a major blaze. Many of the hillside streets are dead-ends and 4 to 10 feet narrower than the recommended 22-foot width. A skinny roadway means one good stall would put fleeing residents on foot and force fire engines to re-route, wasting valuable time.

"Say the fire begins with an offshore wind," Moritz said, like the one that helped spread the Mount Vision Fire. "It creeps downhill, then it gets pushed by one of our easterly winds, which are Marin County's version of the Santa Ana winds - hot, blowing in from the east and very strong.

"You could have fire burning from the top of the mountain, and from down below, and all those people on foot because the roads were blocked would be trapped in between them."

In a worst-case disaster, every town around Mill Valley would be subjected to flames, and the conflagration would end only when it had burned either to the bay on the east or the ocean on the west. Just counting the bigger towns from Kentfield to Sausalito and over the mountain to Stinson Beach, that means nearly 50,000 people and more than 23,000 homes would be at risk.

Those who live in the danger zone shrug off the nasty possibilities as part of the bargain for getting to live in one of the most desirable areas of the country; Mill Valley's median home price is $1.25 million. Most give at least some thought to preparation. But once you've cleared brush around the house, refitted the roof with fire-retardant shingles and the like, there's not much else to do but hope fate treats you kindly, they say.

"We're very focused on thinning our trees, keeping the roadways clear and cutting our underbrush, but not matter what you do, man takes a gamble when he comes into areas like this that are historically hot and have naturally occurring fire," said Barbara Sykes, 75, who has lived in her shingle-sided, hand-crafted mountain house on a slope overlooking Mill Valley since 1976.

From the sprawling porch at the back side of her home, Sykes has a view all the way to the Bay Bridge. Mill Valley looks like a fairyland of wooded cottages; the homes of rockers Sammy Hagar and Carlos Santana are minutes away.

"I'm a real nature lover," she said Wednesday. "But when that easterly wind starts blowing, I always realize that if a fire happens here, the best we can do is just try to get out of the way."

A few miles up Mount Tamalpais, at the Throckmorton Ridge Fire Station, Marin County Fire Department engineer Don Keylon cast a wary eye on how vigorously the winds were flapping the flags at the station entrance. The wind was blowing about 10 miles per hour, and he didn't like that.

"We regularly take the fuel moisture reading here, and the fuel load right now is at 64 percent," he said. That means the moisture is at 64 percent of normal in the wood.

"Sixty-six percent is what we consider critical, so I'd say we have to be pretty careful right now," Keylon said. He pointed to a wide canyon leading from Mill Valley straight up to his 900-foot-elevation station.

"If a fire comes up through one of the drainages (cuts in the land) down there, it'll be kind of like a chimney," he said.

"Like a blowtorch. Not good."

Shrubbery dispute leads Anaheim woman, 65, to shoot neighbor, police say

By Dave Mckibben, Los Angeles Times Staff Writer 11:11 AM PDT, October 1, 2007

A landscaping dispute on a quiet Anaheim Hills street turned violent Sunday afternoon when a 65-year-old woman shot her neighbor in the shoulder and then barricaded herself in her house before surrendering, authorities said. Police said the argument began about 3 p.m. when Anita Spriggs apparently started trimming the hedges of a fence she shared with her next-door neighbor, 64-year-old Gary Hall.
"Spriggs then grabbed a handgun and shot the victim in the shoulder," said Sgt. Rick Martinez of the Anaheim Police Department. "We're not sure where she got the gun."
"Neighborhood disputes are not unusual," Martinez said. "But for it to elevate to this, especially on a quiet Sunday afternoon in a quiet neighborhood, is rare."Hall was taken to Western Medical Center-Santa Ana with non-life-threatening injuries. Raylene Hall, his wife, said Sunday's altercation was not the first her husband has had with Spriggs. "This has happened many, many times before," she said.Raylene Hall said this morning that her husband is still in the hospital.
"The bullet went through his shoulder and shattered it," she said. After the shooting, Spriggs went back into her house. About a dozen officers blocked off the street and evacuated surrounding neighbors on East Greensboro Lane. Over the next 90 minutes, police tried to persuade Spriggs to come out with a bullhorn and by phone. She surrendered just before a SWAT team arrived.
Spriggs was booked into Orange County Jail on suspicion of attempted murder.dave.mckibben@latimes.com

My Lost Blog

Bizarrely, this Blog vanished and reappeared as an Indian Blog. Now after complaining to Google, I've got my Blog back, sort of.

They stuck a 0 into the url and left my old Blog title with the Indians.

This can only confuse my loyal readers; I hope youa re finding me with the 0 (zero) and will continue reading.

I am truly in the dark as to how this happened. If any of my readers have a clue, let me in on it.

Thanks.

EcoSpeakers

I'm pleased to let you all know that both Ray Moritz (the popular San Francisco Chronicle "Ask an Arborist" columnist and, not incidentally, my husband) and I have both joined the team of EcoSpeakers on the subject of the Greening the Urban Environment. The EcoSpeakers homepage is at http://www.ecospeakers.com This is a great organization which provides speakers on many environmental issues.

Ray will talk mostly about his work in urban forestry, helping home owners and public agencies with tree issues. He's also a fire ecologist, so much of his work is in that area. As a "forensic forestor," Ray works with attorneys on legal cases involving trees, including wildland fire, tree hazards and liability issues. He's also a very entertaining speaker.

We are pleased to join the likes of L. Hunter Lovins, Paul Ehrlich, Huey Johnson, Betsty Rosenberg and others who are members of EcoSpeakers.

You can also check out Ray's column on the first Saturday of the month in the SF Chronicle Home section or at sfgate.com http://www.sfgate.com/cgi-bin/qws/ff/qr?term=%22ask+an+Arborist%22&Submit=S&st=s or click on the Ask an Arborist link above.

In other news, I am pleased that this Blog is generating interest and I have been fielding calls from all over the state! Thanks for reading Land Use News. Your comments are most welcome.
