"It's amazing how many nutcases go out and start more fires when a fire makes the news."

Firestarters are deeply rooted in some serious pathology. My sister was a host home provider for homeless and emotionally disturbed kids for several years, and one theme she found repeatedly in a frighteningly large percentage of them was the propensity to start fires.

Today I was thinking about Arverne and Edgemere, two seaside communities in Far Rockaway, New York, that my parents would drive us through during the late sixties (I am sure native Noo Yawkers toggles, shane, and ross will remember).

It was an old resort area with hundreds of blocks of abandoned wooden bungalows and Queen Anne mansions. The City designated much of it a slum clearance area and, in their infinite wisdom, chose to warehouse large numbers of psychiatric patients, many of whom were sexual predators or had serious past histories of abuse, in institutions or out.

Many of them would hang out, wander about unchallenged, and set fire to these old structures. It was said that some of the arsonists set these fires to facilitate orgasm; others did it simply for kicks, and held impromptu contests on whose bungalow would burn brighter.

Urban legend held that incoming pilots on approach to JFK Airport would home in on a Rockaway fire. As the years went by, I remembered watching, during our infrequent drives through the communities, what was left vanish into burnt wrecks and piles of sand.

It was sort of a precursor to the more obvious fires that later plagued neighborhoods closer to our own, in the Bronx and Brooklyn. These were far more deadly, and equally senseless, but there, greedy landlords and tenants desperate for priority placements on the housing lists, but the Rockaway fires stand out in my memory because they were set for ENTERTAINMENT value.

When you are a kid and you hear your elders discuss such things and see the aftermath for yourself....well, what a weird intro to human nature!

It's a pretty apocalyptic regression to what is happening in California, knowing at least some of these fires, in so many separate locations, surely have to have been not only deliberately set, but by more than one arsonist.

On the radio, they are speculating that at least one of the fires may have been caused by some sort of beetle.
 
Re: I'm safe up North:

I'm way North from these Fires, at about 7-hours driving distance, but if the Winds start changing direction, we might get some Smoke up here, although I know that it would have to be quite a lot of heavy Wind and for a long time.

I will also say some Prayers for those who are in or near that area and hope that those of our AW-ORG people down there are safe and hopefully none or minimal if any damage and in no danger.

Peace, Blessings, Prayers and Friendship Hugs, Steve

I think there are a lot of rumors and speculation around these fires. Estimates range from 500,000 evacuated to 1,000,000. With that type of broad estimating it's hard to know what the real number is. It also seems odd to me that smoke could be detected in New York when the winds are blowing the smoke from east to west and satellite photos confirm it. It's just the usual case of information around impacts of a natural disaster becoming embellished as it passes from person to person.

Today there's a weak sea breeze off the southern California coast so things are improving. By the weekend a weak weather system could help to moisten things up further. If all goes well the firefighters could get the upper hand on most of this in a few more days.
 
Smoke . . .

I was out of town from last Tuesday to Monday afternoon, first in Sacramento for a business seminar through Saturday, then visting friends in San Jose and Morro Bay. When I drove down the 101 from Morro Bay on Monday everything was clear until I hit Ventura where the 101 turns east. You could see the smoke in the air, probably from the Malibu fire.

I live about 12 miles from Malibu as the crow flies, but on the other side of the mountains so I didn't anticipate too much smoke making it through. Oh was I wrong, it has been nasty here, with the smoke probably being blown up Topanga Canyon. It has really kicked up my allergies, but being in an older neighborhood well away from any chapparal we're safe so I'm not about to gripe too much about a stuffy nose and sneezing.
 
Methinks we need to start building with concrete and have (standing seam) non-combustible metal roofs instead of combustible asphalt shingles.
I'm thinking concrete can be built to withstand earquakes, obviosuly, n'est-ce pas?

For exisiting construction, in places where there is no frost, does it makes sense to have a lawn sprinkler (think the golf course kind that wets a huge circle) installed on the roof that will protect the whole house? Worse comes to worse it can draw from the swimming pool.........

Aren't there also landscaping requirments to prevent the spread of fires (to homes) in dry climes? I forget what the procedure/concept is called........
 
Fireproofing homes

It's not as simple as putting on a metal roof or putting up concrete walls.

Metal roofs themselves don't combust, but they are excellent heat conductors, and can ignite the wood underneath unless there's plenty of special insulation. Stucco is basically a type of concrete, and rather fire-resistant. But it doesn't stop the heat radiated from a big fire from going through the windows and igniting the rooms inside. For this, one needs insulated steel shutters. That's assuming someone will be around to shut them in case of forest fire.

Then there are the eaves. Good building practices usually call for ventilated eaves. But ventilated eaves can also result in fire entering the structure through the vents.

Tile or slate roofing is the most fire-resistant, but it's also quite heavy and can be a real problem in an big quake. Not just from tiles falling off the roof, but from all the extra weight which may torque the underlying structure in a big shaker.

Let's face it: if you build your home in the middle of chaparral or dry forest, and don't clear vegetation at least 30 feet on all sides of the home, there's not a lot you can do to save the home if the surrounding land is engulfed in flames. For small lots (typical 1/6th acre lots in the Oakland hills, for example) that can mean no vegetation to speak of on most of the property. Hey, if I wanted to live that way I'd move to El Paso.

Even so, with houses set less than 100 feet from each other, just the heat from one structure burning can set the other ablaze. That was a big problem in the Oakland fire: putting out a house fire is far more complex than putting out a brush fire, and the firefighters there said once a home on the edge of the wildlands caught fire, things got a lot more difficult to control.
 
My cousin and her husband live in Rancho San Bernardo section of San Diego, they have been staying at the QualCom staduim for 2 days, don't know if thier home is gone or what, the road is blocked and things don't look good. However, they have a cell and people to the north mountian neighborhood say that things look OK in the neighborhood, but there area few burned houses, one good, one destroyed, it is really random.
They have a stucco home with a tile roof, those homes tend to resist cinders blowing. We are all hoping.
 
Concrete and tile . . .

Concrete doesn't burn, and neither does steel. However, cast in place concrete is a hugely expensive material to build with due to the hand labor required to construct the formwork and install reinforcing steel, and has terrible insulation properties as well. Concrete block is a bit cheaper, but still expensive once you factor in all the steel, and it still has poor insulation value. In the right climate, thermal mass can be used to offset the insulation issue but you don't need concrete in all of the walls to do this. Concrete is also far from a green material in that producing it makes lots of CO2, and the weight of concrete walls requires even more concrete in the foundation. I love the look of properly done cast in place concrete, but I doubt I'll ever get to design such a building due to the costs and environmental issues.

Most roof tiles today are made of lightweight concrete or fiber-cement and aren't much of a problem structurally. A tile roof on a wood-framed stucco building is a pretty good way to go in fire-prone areas, especially if you have minimal, sealed overhangs and ventilate the attic through roof vents with louvers and screens.

One issue rarely talked about is the popularity of vinyl windows. They're cheaper to make than wood, don't rot, and have good thermal properties, but at some point the vinyl will melt and once the glass falls out all bets are off. I have no idea if this has been a factor in some of the damage here. I don't like vinyl windows because they rarely look as good as a real wood window, and in a fire I think I'd put my money on an aluminum-clad wood window. I might be wrong on the latter point though . . . I'd really love to see some research on the matter. All-metal windows are certainly the best for fire resistance but they're expensive and must have thermal breaks in the frame and sash if they're to have decent insulation properties.

Regarding using sprinkler systems to stop fires, I once worked on a house on a two-acre hillside site next to a state park which had special provisions for just that. The system worked like this: if activated either manually or by special sensors, the sprinkler system would turn all zones on full force. If the system dectected low water pressure, then it would switch on a pumping system to draw water from the pool. In the event of a power failure, a generator system would start up to power the pumps. Needless to say, this was not a low-budget house and the owner was a computer guy who understood how to keep the system up.
 
There are some fire-resistant homes that have been built in the Oakland Hills fire zone. But I don't think any of them have cast-in-place concrete walls. Their landscaping tends on the desert type. There were a number of articles in the local papers after the '91 fire storm about what it takes to fire-proof a home. Codes have been updated and what's been built up there is definitely safer in a fire season than before, if for no better reason than that the 10 meter safe zone around structures has been rigorously enforced.
 
~However, they have a cell(mobile phone)........

Heard on the news that oh so many keep calling their temporarily evacuated home and have some encourgement when the answering machine picks up.

It could technically now be sitting (outside) exposed to the elements, but one can hope...........
 
As long as it's a real free-standing customer-owned answering machine and not the telco's voicemail product. Voicemail will pick up just like normal even if the house is gone since all of the equipment is located in a telco facility.
