Is water seeping through the plaster?

Our property is located on a slight slope on the inside of a curve. Because we did not align ourselves with the highest point of the former construction road, our property is partly a little below the level of the road. Now we have noticed that during the heavy rains of the past weeks, water is pushing up from beneath the pavement both partly in our driveway and on the public road. This water has now naturally turned to ice.

We have two drainage channels that normally collect and drain this water. But on public ground there is a manhole too high up the slope and another too far behind the curve to effectively collect water. Is this normal or was there possibly shoddy work done during the road construction?

If you expect good answers, it is recommended to describe the problem more clearly.

Do you have two drainage channels on your property, on the right and left of the driveway? Or where are the channels? And do they have an insufficiently designed slope, so that water remains standing in the channel?
You are responsible for the drainage on your property.
Or what exactly is the problem?

I don't quite understand the part about the public road. It is surely paved and therefore impermeable to water?

As for your paving...with a subsoil that has poor infiltration, water remains standing in the gravel for a certain time. If you have a depression there and it rains a lot, water can collect there and push back up. Water can also seep sideways across the gravel along the slope. A channel there helps against the symptom but not against the actual problem. If your paving substructure and the joints are full of water and it gets cold (like currently), this can lead to frost damage.

I will attach a few pictures. My explanation might not be so optimal for an outsider.

First, the view out of our driveway:

Then the view uphill:

And finally the view downhill:


You can see (or recognize) the water is pushing up from underneath through the pavement. In all other curves in the development area, at the spot where I am standing when I took the two photos on the street, there is an additional drain in the middle gutter to let water flow off. Only in this one there are just the ones I marked. The one opposite the driveway feels too high on the slope. The second one, further down the street, is currently not reached at all by the ice or the water.

In my driveway, the water is pushing up from underneath through the pavement at the places where it is now frozen. Normally, it would then make it into the drainage channels, but there was probably too much water and it got too cold too quickly, so now I have ice there.

Does this look "normal" to you or should I maybe raise a fuss with the city?

On the phone it looks like there is a dip in your driveway. So no slope towards the gutters. ==> Poorly constructed driveway. But the picture can be deceiving.

I dug up another picture of the driveway from above. The red arrows point to the channels. The slope also ends approximately at the red arrows. On the left is the channel in front of the garage, the garage is dry and the water in the channel is also not standing. The water, when it rains, does try to go in the right direction. The water you see here seems to come from below, as it remains there for quite a long time after rain or pushes up from below. As you can see, the street is wet even though it is no longer (raining) and the upper parts (uphill) have already dried or are drier.
