Oh no! I wish I could help!

From what I saw at your photos... I mean your garden... I think that you know the problem from your own experience.
Thanks for chiming in!

Too much rain or no rain, too hot, too cold, that's the world today and it's not finished...
Hang in there, Marta.

It's not the world (and weather) at fault. People are.
I wasn't born yesterday.
I remember droughts and floods, abominably hot summers and ultimately cold winters.
We used to deal with it. Now people think that modern life and technology protect them from those common inconveniences.
My current problem illustrates what happens when people forget how things were done not so long ago, when their ancestors actually cared for environment (and ideology of ecology was not even invented yet!)
You see, we have old drains and flood control channels here where I live. The system was built at least 100 years ago and functioned perfectly then and was still in good condition twenty years ago. Then yuppies came and started building their big houses, cutting and plugging drains, filling channels with dirt and soil, paving everything and so on.
I live by a road that used to be a dirt road (partly mine) and at its other side there was a ditch large enough to absorb all water coming from my property (and from my neighborhood). Then the previous mayor decided to use some EU funds to asphalt it. They did away with the ditch, they ruined existing drains. The new road is like a dam. No wonder water gets out of control.

Oh no. Flood protection would be my business. Good look Marta!

There is no protection against people irresponsibility and thoughtlessness, Berny. That's what I am dealing with. Water is not a problem. People are.

sh.....
wish you all the best!

Thank you, Markus!
Good news is that there was no rain since Thursday and I managed to get rid of water in my basement. I pumped it out into sewage system. It's illegal but what can I do?
Now I am stoically waiting for another round: next storm = next flood

Sorry to hear about your awful problems. Lack of care (or something more $inister, perhaps?) seems to be a common feature of land development. In the UK developments still seem to be constructed on river flood plains ...
