Is the slope from the street to the house normal? Please provide feedback!

Hello. We have received our building application documents ready for signature. There I found a document with height specifications from the street and the property. Somehow it seems to me that all the water from the street in the west would flow over the paved parking spaces towards the house due to the slope, since the house is only planned at 97.45 hM (house corner points roadway top edge paving) or 97.50 hM (top of ground floor screed). Or am I mistaken and can we leave everything as it is? I would be grateful for any ideas. After the house is built, it cannot be set higher anymore... PS: There is a street to the west, in the other directions we have neighbors. To the south, according to the building authority, we are allowed to fill up to 1m, possibly with L-stones according to the builder. A basement will not be built.

I wouldn't worry about the street, it has a clear slope to the south

Ask the planner why he chose this height. If there is no plausible reason, I would go one step (17cm) higher, even though I don't see any major problems with the current height.

That sounds good. So let's leave aside the rainwater that comes from the street. But what about the rainwater that falls on our paved parking spaces? That should flow towards our house, or am I wrong?

There has to be a drainage plan for that, right?

The site has a north-south slope, which the planner has averaged in order not to have to fill too high in the south. That costs money. Thus, the northwest corner is about 0.4 m above the house level, the southwest corner similarly below the house level. You need good drainage for the parking space, or, what I would do, build it out of gravel with granite chippings, Rhine pebbles or similar on top, which works very well and absorbs quite a bit of water. Use retaining walls as little as possible, do as much as you can with earth, these walls are expensive and easily spoil the usability of plots. Karsten
