In a city full of special news comes something even more special than usual.
The columbarium at the municipal cemetery on the island of San Michele is aging and deteriorating faster than some of its past and future residents. This means that the dear departed are not resting in much peace anymore, and they’re not going to let you be feel too serene either.
Today the Gazzettino announced: “If you want to go put some flowers on your loved one’s tomb, you have to wear a helmet.”
Grieving relative takes cover. (Credit: Il Gazzettino).
Yes, lack of money (“no ghe xe schei“) has brought us to this: A cemetery where you have to protect yourself from your relatives even after they’re dead. Three hundred final resting places have become public hazards.
I can hear the helpful advice now, as you set out with your little bunch of chrysanthemums:
“If you’re going to visit Uncle Max today, watch out — he could be throwing bits of rock and cement at your head.”
“He never liked me very much….. “
Veritas, the private agency that oversees the cemetery (and, let it be noted yet again, also disposes of Venetian garbage), says that the necessary funds for repairing the cemetery have been allocated by the Special Fund (money being spent on something that isn’t part of the MOSE floodgate project? Astounding) — but that the money hasn’t been freed-up yet.
“Dig we must.” It takes on new resonance when the guys are drilling and backhoeing around your family. So meanwhile, wear your hard hat. And try to ignore the fact that the stuff that keeps falling on your head will probably not be raindrops. It could be cousin Lola.
It’s probably way past everybody’s bedtime, so I’ll wrap up this little philippic.
Imagining momentarily that a satisfactory conclusion could ever be reached in the Gordian convolutions of the “floodgate” project, permit me to make a few very brief observations.
First, let us make a concerted effort to ban all those irresistible emotional words that acqua alta seems to force from journalists’ subconscious. “Venice under siege,” is a common one. CNN said that the high water of December, 2008 had been caused by the Adriatic “bursting its banks.” (Banks? Bursting? Are we in Holland?). The Discovery Channel stated that the high water was “cannibalizing” the city’s buildings (OMG). And on and on. One could smile if this kind of reporting wasn’t cannibalizing common sense.
If the city can't manage to find some money for people, even when we've got MOSE we may no longer have any people. Good thing we have pictures.
When I think about it really calmly, it appears to me that it’s actually impossible for the planners and builders of MOSE to be able to make any promise (guarantee, statement, claim, whatever you like) about their creation that they can prove is accurate.
There are simply too many unknowns in the many different scenarios devoted to its use: How well it will function — that’s the big one — how much its maintenance (routine or extra) will cost, where the money for feeding and caring for it will come from, etc.
Every claim from its proponents is supported so far only by data assembled by them.
Probably the two major areas of concern for its success are:
First: How high the highest tides are likely to become. Some estimates only give MOSE 100 years of usefulness, after which the highest tides will spill over its maximum height. The frequency and duration of these exceptional high tides are also subject to interminable debate. But nobody knows.
I wonder who will hang out the laundry everybody (including me) loves to photograph. Maybe they'll hire somebody.
Second: How well the individual caissons will remain aligned. As I mentioned in my last post, if they begin to lose their perfect uniform surface (even if only one of them doesn’t rise as high as its neighbor, or the seal begins to leak), the strength of the entire “wall” of caissons will be compromised.
I have rowed against the incoming tide at the inlet at San Nicolo, in normal weather with no hint of wind or surge, and it is nowhere near being a joke. If the barrier isn’t perfect, the tide will come in whether MOSE is ready or not.
But let us not be downhearted. Let’s say that the machinery functions perfectly, precisely as planned. Let’s say that exceptional high water occurs ever more frequently. as expected. Let’s say that every prediction is fulfilled, even though there is no way to assume they will be.
Here is the real question: Has Venice been saved from anything except some water in the street for a few hours?
The true inundation, the most implacable and destructive, is the endless tide of tourists. The number increases 3 per cent every year; in 2009 it reached 21 million in an area of about three square miles.
No need to waste any time worrying about the old folks, they'll be gone anyway.
Whether this fact inspires emotion or not, it is more measurable, and predictable, than the inexact, politically driven “science” that has given birth to MOSE.
So let’s say that while assorted interested parties continue to water and fertilize the popular obsession which the press has with acqua alta, some very real problems continue to be neglected.
Young families will continue to move away because they can’t afford Venice (housing, primarily, though lack of jobs is a close second), the older generations eventually die off, and before MOSE has become obsolete the city will be devoid of residents. In their place will be the tsunami of tourists — tended to by merchants who mostly live on the mainland — which will finally render the city completely unliveable.
So even if MOSE performs perfectly, the Venice that has been “saved” will amount to nothing more than a collection of really old buildings, beautiful or not, according to your taste.
If no comparable effort is made to revive and protect the life of Venice, then even if MOSE turns out to be an engineering marvel to rival the invention of the arch, the once-thriving city will be as devoid of life as Machu Picchu.
When that happens, there’s won’t be much point in vilifying MOSE, or bewailing the triumph of politics and fear over basic municipal common sense.
But unfortunately, and perhaps even unwillingly, even the not-so-old will be gone too.
But it seems clear, even now, before the first button is pushed, that if the time, energy, and billions of dollars that will have been spent to hold back the tide had been dedicated to resolving the chronic, debilitating problems that Venice experiences every day, in 50 years there would still be a living city worth saving.
Having reviewed the barest basics of acqua alta, and the barest technical outlines of the “floodgate” project intended to keep Venice as dry as the Nebraska Sand Hills, I’d better warn you that not everybody is on board.
“This is a way of funneling a huge amount of money to business allies of the government,” a city councilor told TheChristian Science Monitor last year. “There are better alternatives but they were never considered. There is a big question mark over whether it will really work.”
So has anybody spoken up? Only thousands of people. The project been protested, sued against, blocked and stalled in all sorts of ways for 30 years (yes: it’s taken three decades to get this thing to where it is today), and even now the arguments pro and con continue to be lobbed back and forth between the opposing believers.
Construction proceeds at the inlet at San Nicolo, the one closest to Venice. The artificial island in the middle, built to accommodate construction equipment, has already affected the tidal flows. It will not be dismantled.
There have been a few times when it appeared that perhaps the project would be annulled for various reasons: lack of money, the bizarre absence of the required Environmental Impact Statement, legal loopholes that kept being found and then quickly closed. But nothing has been able to stop its implacable progression toward completion. It’s like throwing gravel at the Kraken.
By the end of 2009, despite all the myriad stops, starts, and slowdowns, 63 percent of the project had been completed. There isn’t enough money to restore historic palaces and churches which are visible every day, but somehow money has been found to block exceptional high water, an event which might occur four to seven times a year. Or maybe not at all. You may have noticed that the weather is not operated by the Swiss railway system.
But doesn’t everybody in Venice want to save their city from the sea?
In a word: No. At least not everybody in Venice wants this to be the way to tame the tides. In fact, it is difficult to find anyone who is not directly benefiting from the project who thinks it’s a good idea. Quite the contrary.
There are four general categories to which most objections belong. Let’s look at the them:
Political: Not much to say here, because this is a sphere in which nothing is ever resolved. The political fortresses from which accusations have been hurled like stone cannonballs are very well defined: right, left, extreme right, extreme left, and a mass of foot soldiers in the middle with all sorts of commingled ideas. But if you don’t belong to some group, nobody will ever listen to you (not that they listen so much anyway). Only thing is, each group has an agenda which includes lots of other issues as well, so if you join one to reject the MOSE project, you could find yourself on mailing lists as being against a batch of other undertakings as well. Maybe you’re not against those, maybe you don’t even care.
The lagoon has no idea there is a famous city sitting out there somewhere.
Others point out that the Special Law for Venice, by which federal funds are earmarked for the city, specifically authorized interventions to stop pollution and re-establish the morphologic equilibrium of the lagoon. It doesn’t appear that MOSE will satisfy either of those requirements. Au contraire.
Even more important, each side considers it a good day’s work if it has managed to frustrate or thwart the other. No other result is really necessary. This reality is the cholesterol in the political metabolism, hardening and constricting the arteries through which ideas and energy and good will might otherwise have flowed to produce something beneficial to the organism (the city and the lagoon) as a whole.
Economic: Every enormous public work since the Great Pyramid of Cholula (and perhaps even that one) has exceeded its projected cost. The original date of completion was given as 2010. This has now moved to 2014. Hence the costs have also changed. MOSE was budgeted at $4.5 billion, more or less, depending on whose estimates you follow, a number which it has now overtaken without even slowing down to wave. In 2008, the cost had risen to $7 billion.
There is also the cost/benefit aspect to consider. I think it’s fair to say that anyone who is not personally involved would concede that the costs and the benefits of this colossal undertaking do not come anywhere near matching up.
One foreign newspaper reported that $30 million a year is lost in business each time the Piazza San Marco floods (meaning that these 40-some shops can make $30 million in six hours, when the tide is in? Wow…. ). But let’s say acqua alta does cost $30 million, even if that number is cited only by the people who would benefit from the effects of such a prediction.
MOSE, as already mentioned, not only has cost $7 billion by now with 35 percent and two more years to go. Few if any mention is made of the estimated cost of annual maintenance of this behemoth: a mere $11.5 million. Of course, this will be eternal income to the interested parties. The project will be finished, but maintenance is forever.
Plenty of people would like to keep living here, if they could. But to the locals, it can seem like it's one of the great forgotten cities of the world.
But that isn’t the crux of the objections to its price tag. Simply put, it’s that money dedicated to MOSE is lost to anything else.
Stories which focus on the cost/disturbances inflicted by a few hours of water on the ground don’t tend to refer to the financial scorched earth the MOSE project has made of the quality of daily life for everybody everywhere in Venice, not just the shopkeepers around San Marco. Paying for this project, which might bring a temporary benefit to the city a couple of times a year, has deprived the city of the money required for numerous, more humble needs (schools, ambulances, restoration of monuments and private buildings, etc.).
Just about every facility or service which is important to city life, more important than the occasional need to put on the Wellies, has been cut in some way. The administrations’s constant cry “We have no money” tends not to explain why.
Environmental: When UNESCO designated Venice as a World Heritage Site in 1987, it specifically included the entire Venetian lagoon. It is the second-largest wetland in Europe (Europe has lost 2/3 of its wetlands in the last 100 years). It is vital area for plants, fish, and birds, some of which are already endangered. Every year some 200,000 birds winter, nest, or pause here in their twice-yearly migrations. One could make a reasonable case that the lagoon has a value which rivals that of Venice.
Local, national and international environmental groups have raised countless alarms about the effect of this project on the lagoon environment. Prominent among these are the World Wildlife Fund, LIPU (the bird people), RAMSAR (international wetland protection), Italia Nostra, and more, down to a local citizens’ group called simply “NoMose.”
In one of many reports, Italia Nostra summarized its concerns: “The dams will render permanent the Lagoon’s environmental imbalance: The deep channels dredged in the last century through its outlets will become concrete. The erosion that is now eating away the Lagoon’s precious wetlands would become permanent, and this rich coastal lagoon, protected by European law, would be transformed into an area of open sea.”
What is so elegantly called a cavaliere d'Italia (knight of Italy), in English is merely the black-winged stilt. Still beautiful, though.
The deepening of the channels to accommodate the cement frame for the caissons has already intensified the tidal flow — I can see and feel it every day. Faster and stronger tides mean many things: More erosion of the bottom sediments (one of the defining characteristics of a lagoon environment), consequent damage to the eelgrass which serves to anchor the sediment and which provide a habitat for many small marine species, and so on up the chain.
My favorite of many favorite ducks is a wintering species called a "tuffetto" (little diver). Their arrival and departure are parentheses around the winter.
There is also great concern about the physical impact of the materials used, specifically the caissons’ zinc plates (zinc is forbidden by European law) as well as the anti-fouling paint, which contains many toxic chemicals such as TBT compounds, assorted heavy metals, and solvents. Coats of anti-fouling paint have to be periodically renewed, so that will contribute another dose of this stuff to the environment. Damage to the lagoon and the Adriatic is seen as virtually inevitable. I must mention that the builders deny this.
Data and forecasts which justify the project have been questioned by many different sources. Some of the data does not appear anywhere but in the builders’ documents.
Engineering: Plenty of engineers from assorted countries, those who are not directly involved in the project, have always voiced doubts about whether it’s likely to work the way it’s supposed to.
Another perspective on the system, which clearly shows the the caissons fitting snugly together, forming a perfectly even wall. It will be great if nothing shifts or leaks.
Some of their concerns are:
It has never been completely tested.
The only positive assessment rendered by an independent panel of engineers was restricted to saying whether the design could function as intended — that is, whether it would work as designed. Virtually all other independent evaluations have been extremely cautious, if not negative. No engineers except the builders, to my knowledge, have risked saying whether it should be built. Maybe that’s not what engineers are supposed to do. UNESCO wrote an analysis in 2003 which concisely evaluated the project’s drawbacks, including the meteorological predictions on which it is based.
There are discernible aspects of the design which must ALWAYS function PERFECTLY (difficult in a salt-water environment),or they won’t perform the way they’re supposed to. For one thing, there is a high risk of the seal between the caissons not being watertight. If water begins to pass between the caissons, the wall they form could be dangerously compromised (fancy word for “weakened”). If the caissons for any reason do not align perfectly, ditto.
If for some reason encrustation of any sort remains on the caissons and/or their anchoring hinges (salt-water is great for fostering encrustations of minerals and critters), the barrier may not rise in the manner or at the rate necessary.
If sea-level increases fulfill the darker prophecies, not only will the caissons have to be used more often and kept in place for longer periods of time than predicted (undergoing stresses for which they were not designed), but eventually their maximum height may not be enough.
After decades of legal battles, the design was already obsolete before construction even began. Thirty years is an eternity in engineering terms. (Imagine buying a car designed 30 years ago.) Whatever its flaws, it should have been modified or updated in some way by now. But no.
Perhaps most important, critics point out that this titanic construction flouts several principles sacred not only to the hydraulic engineers of the Venetian Republic (not exactly amateurs) but also to commonly-accepted principles of environmental and engineering prudence. Those principles are:
The project should be gradual, to permit evaluation of the results obtained at each stage and, if necessary, permit changes to the original plan. This obviously isn’t the case here.
The project should be reversible. MOSE obviously isn’t.
The project should be experimental. By “experimental” the Special Law clearly intends that a project should be tested experimentally before it is definitely approved and funded and built. That never happened.
How did this project ever get approved?
I can’t swear that I know. Here is what I do know: That the project was assigned to the Consorzio Venezia Nuova, a consortium which the city has exclusively authorized (some have used the word “monopoly”) to intervene in the lagoon. This consortium is made up of more than 20 Italian engineering and construction companies — in a word, businessmen. Scientists who promote or defend the project are often consultants for the consortium.
So here we are. It’s too late to be any use, but I’d like to recall a comment by Wendell Berry, the farmer/writer/environmental critic.
“A good solution to a problem,” he said, “is one which does not create new problems.”
Now that I have pounded the subject of acqua alta into unconsciousness, you may be wondering if there are any solutions. It’s not unreasonable, I guess, to want to suppose that there could be some action(s) that would limit or even prevent water from inconveniently covering your street, even for only two hours.
Certainly many of the articles which continue to appear, year after year — there must be a workshop in a cave where some crazed Geppetto keeps producing stories on how Venice is being engulfed — tend to make it sound as if Venice’s health and future happiness depends almost exclusively on keeping the water out.
This is not acqua alta, it's just acqua.
So let me urge you, before we continue, to disregard, as far as you can, the drizzle of extravagant statements drenching almost every article about this project. Such as comments by journalists in love with their clever way with words (“…soaked Bruno Maglis have become more the rule than the exception…” You’ve got money for Maglis — or for any kind of shoes — but you haven’t figured out that you can take them off to keep them dry? Wow… And by the way, it isn’t true), or this, by an Italian professor of physical oceanography at MIT: (“”The gates are really the only solution.” Really? The only?), or the claim that high water really, really distresses the old people. All the old people I’ve ever talked to are the ones who make the least fuss about it of anybody.
The good news: There is no lack of useful and feasible ideas on how to limit or prevent high water in the city. In fact, we have been inundated by a plethora of proposals, many of them simple, easy, not damaging to the environment and cheap.
The bad news: Only one solution has been chosen, and it is none of the above. Sometimes referred to as the “floodgate project,” this savior is called MOSE. It is the biggest, most expensive, most drastic, most irreversible, heaviest-impact-on-the-lagoon-as-a-whole solution that anyone could have imagined. I say that because if there were a solution that could have been more drastic and more expensive, they would have picked that one instead.
What is it?
MOSE stands for Modulo Sperimentale Elettromeccanico, or Experimental Electromechanical Module. It consists of a sequence of a total of 79 steel caissons — boxes, really — lying on the lagoon floor, which can be raised to form a wall which will block an exceptional incoming tide.
Where is it?
A view from the Adriatic, looking over the Lagoon and the three "mouths," or inlets, through which the tide comes and goes every six hours. (R to l): San Nicolo, Malamocco, Chioggia.
The Venetian lagoon is enclosed by a long strip of barrier islands which block the Adriatic Sea except at three inlets (called “bocche,” or “mouths”) through which the tide passes every six hours, coming in or going out. This exchange of water is crucial to the lagoon’s ecosystem.
How does it work?
Each of the three “mouths” of the lagoon has been dug to accommodate a concrete frame installed on the bottom and sides of the channel. Attached to this frame, by means of hinges, are the aforementioned 79 metal boxes which normally will lie on the channel bottom, filled with water.
These diagrams show the steps involved. Note that one caption states that there 78 of these caissons; there are 79.
If an exceptional high tide is expected (or more than 110 cm [3 1/2 feet]) above median sea level, the water will be pumped out of the boxes and compressed air pumped in which will cause them to rise up and form a wall preventing the water from entering the lagoon. When the tide subsides, these caissons will be filled with water again and they will return to their dormant state on the inlet floor.
When will it be used?
The job of this colossal construction is to prevent — not just any high tide, but an exceptional one — from reaching the city. The frequency of a tide of this magnitude is predicted by the city as being four times a year.
Therefore, any high water up to 110 cm is going to come ashore just as it always has, and we will continue to break out the boots and merchants in low-lying parts of the city will continue to stow their merchandise and keep their squeegees at hand to sweep the receding water out the door. Their keening laments will also be primed and ready to go.
Who thought this up?
As with many large public works, it is the love child of politicians, engineers and builders. In this case, an assortment grouped together as the Consorzio Venezia Nuova (New Venice Consortium). These are not lagoon-huggers. Many of its members are in business, often doing the sort of work that MOSE requires.
1973: The Special Law for Venice is passed, which declares the city’s welfare to be of “preeminent national interest.”
1975: The Ministry of Public Works announces an international competition for project designs which would limit high water. Five projects are accepted for evaluation.
I will leap ahead here and spare you the year-by-year chronicle of yes/no, he said/she said, did so/did not, claims and counterclaims. It’s like Jarndyce and Jarndyce. A full account of this 30-year struggle would be a ponderous assortment of lists of names and companies and government agencies and ministers, environmental organizations, suits and countersuits at every level, from Venice itself to the European Court of Justice in Luxembourg. By now, the only people in the world who have not been involved in this in some way are you and me.
By now, 63 percent of the work is finished. But the controversy is still very much alive.
