Also of note, the water system built after the 50's as a result of the recurring floodings in the area [1] [1] https://en.m.wikipedia.org/wiki/Delta_Works

It is such a joy to see a methodical and rational long term planning response to a problem.

Makes one wish there was a longterm planning organ in a democracy, who could veto on short term solutions.

Nice project, it makes Berlin appear like a progressive, nice place to live. But actually it has so many problems that should be solved first before even thinking about things like this. For instance total failure to integrate the Muslim minority, increasing racism against Jews (Men usually wear a baseball-cap over the Kippah in public due to fear of being beaten up), prices that double each 7-10 years while salaries…

> increasing racism against Jews This is true. > Men usually wear a baseball-cap over the Kippah in public But this is right-wing bullshit. The rise in anti-Semitic crimes is used by Pegida to stir up fear of refugees, Muslims, and Islam, and it's also used by Netanyahu and the Israeli / Jewish right to encourage immigration to Israel. The reality is that the rise in anti-Semitism begins in 2014, prior to the refugee…

> It's tracked the Europe-wide rise of the right, not anything related to "Muslim integration"

Go to any schoolyard and observe members of which ethnic groups use anti-semitic slurs. (I'm not talking about "more frequent", I'm talking about using them at all.)

I seriously implore you to think about what it would be like to be a Jewish pupil in certain districts of Köln or Berlin and implore you to say with a straight face that anti-semitism is caused by the (far-)right.

funny just watched this yesterday night. Was really surprised by it. When you live in Berlin it's not something you see that yet. But of course Berlin is a more green city than something of the size of New York just by being smaller.

Well, that's partly true. A lot of the flooding is due to the fact that the entirety of Texas doesn't care about hydrology, and all that water is ending up downstream, in Houston. There'd still be flooding, and it would still be bad, but a certain degree of flooding was avoidable.

The other thought, I imagine, is that they felt the probability was low that they would see a flood of this scale even within their lifetime; that ended up being a poor bet. Even so, flood insurance is also cheaper when the perceived likelihood of a flood is low.

Since cities usually survive much more than one human lifetime, this is not good reasoning.

My first thought is that it might be hard to prevent decay and leaks into the structures supporting these spongy surfaces. 80cm of water logged soil above a parking garage, for example.

Planting grass on top of parking garages isn't that unusual or new in Germany (though usually done for aesthetic reasons), so I assume this is a solved problem. Sufficiently deep buildings and parking garages might also encounter ground water, so adding soil on top might not even add new problems to the engineering side. Similarly, the rooftop plants are shown on rooftop designs that would already have to deal with s…

Municipalities can (and commonly do) grant a reduction of fees for reducing sealed soil, so it's not only aesthetic reasons. https://de.wikipedia.org/wiki/Niederschlagswassergeb%C3%BChr

Isn't forcible suppression of opposition a characteristic of fascism? Sounds like antifa are, themselves, fairly fascist.

can't be tolerant of intolerance if you want tolerance to survive

Tolerance means that you can tolerate opposing views, that you respect the people who have them. Violence against people you disagree with is intolerance, and is the way of fascism (among others). You cannot create tolerance through intolerance. You can control people through violence and intolerance, but control is the opposite of tolerance.

People build houses, cities don't.

As you almost certainly know, the city controls permissions for every building.

A city that gives planning permission for a development that is probably going to be destroyed with loss of life in the next hundred years is not serving people well.

Ehm, you won't see any Kippah in public because Jews in Germany are scared since decades. I did not say anything about refugees or recent events although these things surely amplified the bad things already happening in Germany since a long time. Go stand next to a (usually Police guarded) Synagogue for an hour and see for yourself how guys leaving the thing put on baseball caps. Unfortunately, this is not right-wing…

I wonder how that is true given that Berlin has an extremely large and militant Antifa presence. I can't imagine anyone getting away with a hate crime here. If your store is even suspected of selling fascist stuff it gets vandalized! Berlin is about the biggest anti-fascist place I know.

Right-wing extremism is bad but negligible compared to uneducated Muslims. There are 5 million Muslims in Germany and 32% say openly they prefer a Sharia-state to a German-democratic state (http://www.br.de/nachrichten/emnid-studie-tuerken-koran-grun...). The left is blind to this because they think it's America's/Europes fault that they behave so badly.

Civil engineering has pretty well quantified the rate at which water is absorbed by certain soils, accounting for groundcover, trees, pavement, local detainment, etc. Berlin's sponge mission is baiscially distributed detainment, working to offset hardscaping (driveways and roofing). In other words, it's a well known and very predictable science, but we (we being US land development industry) has not cared. HOWEVER ra…

Well, that's partly true. A lot of the flooding is due to the fact that the entirety of Texas doesn't care about hydrology, and all that water is ending up downstream, in Houston. There'd still be flooding, and it would still be bad, but a certain degree of flooding was avoidable.

Eh it is wholly true. Distributed detention schemes still have a finite volume of containment, and once the detention zones are saturated, those areas behave equally to pavement for each additional unit of water. 50 inches of water across the majority of Texas with severe storm surge cannot be practically prepared for beyond insurance, evacuation, and/or a boat. To say “it was avoidable” is a strong and expensive assertion requires some hard backup. Heres an introduction to runoff coefficient (disclaimer! exciting stuff!). Everything is based on a “design storm” with a specified duration and intensity, where those two variables lead to a sigmoid curve (as i recall) for runoff, or the greater the intensity and longer the duration, the less water that gets detained. http://www.brighthubengineering.com/hydraulics-civil-enginee...
