The best thing about it, for the non-engineers and poets among us, is that it rhymes.
A less fanciful pursuit today: Supervisory Control And Data Acquisition. When I was in the thick of asking questions about whether the pumps worked, last fall, we had some hurricanes in the Gulf. It occurred to me that they had cameras on the canals; peeling that video would have cost me 10 thousand dollars, they said, in man hours and costs. So I tried for the SCADA data. And got it.
Clearly, you've noticed by now that I'm not an engineer. But when I got the data I could see where the zeros were.To quote Doogie Howser, M.D. for a minute, it doesn't take a genius to see some of SCADA's story. But my aspirations to do something complete in plotting data got dashed pretty quickly.
Nevertheless, engineering is more science than art, after all, and engineers best understand what engineering data does. Maria Garzino also obtained SCADA, and discussed it with the Apariq consultant, Gil Lucas. She spent over a month making calculations from that. I make of that two things: first, that she's still doing everything she believes is necessary to figure out what's happening. And second, that she doesn't sleep much.
New Orleans specializes in muddy waters.
I was living there, covering a “Night Out Against Crime” for my peeps at the brilliant, beautiful, and sadly deceased Day to Day when I met Matt McBride. He was at the Broadmoor night out. Matt is an engineer, a husband, a devoted dog dad, and a tireless advocate for his former neighborhood. He pointed out that sometimes, all I had to do was ask for the information I wanted.
One of the reasons I really understood that I could ask for information comes from what is also one of my favorite ancient concepts of law: the public trust doctrine. I was raised in California law; when I was small, my dad and my grandfather explained it to me, I recall very clearly, in a blue dining room in St. Francis Wood in San Francisco, behind lace curtains like a good Irish house should have. My grandfather said it came from Justinian. I was about 7; I think I found one of his cases in his law reporters a dozen years before I actually learned anything else about who Justinian was.
The day Maria Garzino left Florida for New Orleans, in early May of 2006, I was in New Orleans, interviewing Jurjen Battjes: he first launched me down this river. In person, he’s sort of like if you combined the elongated ovularity of Bert with the glasses of Beaker, and just a pinch of Ernie in his grin. Like a lot of scientists and engineers I’ve met, his affection for what he studies was infectious. We met at the 17th street canal: that canal, and its breach, gets the most attention. But he also took me to the spot at the south end of the Orleans canal where water flooded through a hole left on purpose between the end of the outfall canal and the historic water pumping station, whose brick walls wouldn’t support water of any height either. And to one of the two holes in London Avenue’s canal. All of the canals have houses that back up close to them. For a long time, decisions about the city’s protection have been made piece by piece, pile of money by pile of money. Dr. Battjes said, engineering often can get decided that way; but rarely is it decided well that way.
LA City Councilman Bill Rosendahl’s office has been working with Mar Vista residents to demonstrate a rain barrel project. They’re rolling out the barrels now. (ha!) I plan to go check them out. I was reminded that back in winter, I went up the hill to TreePeople’s village of yurts atop Mulholland to talk to Andy Lipkis and Jim Hardie about the group’s demonstration cistern.
Jim Hardie went down into the cistern for me. Not very far, though – at the time, it was full to the brim: 8 feet deep, 70 feet across, 216,000 gallons of water from the sky. TreePeople thought it would be enough water for the rest of the year.
So I figured I’d check back with TreePeople for an update. Turns out that between mid-February and mid-July, they used just under half the water in that cistern for their climate-adaptive landscape: 46 inches, almost 4 feet, so at 2250 gallons an inch, that’s 103,500 gallons. Keep your fingers crossed for them – they’ll probably need a wet winter to get through 2009.
The LA Times today reports on a proliferation of Asian clams in Lake Tahoe. The clams have been around for seven years, at least; it's in the last couple that they're really taking off. Some scientists fear they will make the lake more hospitable to other invasives, like the quagga and zebra mussels that are all over the Great Lakes, much of the west, and even in the Colorado River system.
Here's one of our invaders:
Quagga mussels sampled from Metropolitan Water District facility near the California-Nevada border. Full grown, they'll be thumbnail size; at this point, they're like really swollen poppy seeds. MWD reports success with its efforts to control quaggas. But their spread remains a concern. I was in the eastern Sierra several times so far this year, and saw inspection stations for quaggas, and boats with inspection stickers as the state now requires. Still, all it takes is one pair of waders, one boat, one person. In the sea, one piece of plastic trash that cut loose from the gyre and lands where it didn't come from.
