ᐅ Is it normal to have a slope from the street down to the house? Looking forward to your feedback!

Hello.
We have received the final construction application documents ready for signature. In them, I found a document with the elevation details of the street and the plot. Somehow, it seems to me that all the water from the street to the west would flow over the paved parking spaces towards the house because the house is planned at only 97.45 m (house corner points, road surface pavement) or 97.50 m (finished ground floor level). Or am I mistaken and can we leave everything as it is? I would appreciate any ideas.
After the house is built, it cannot be raised anymore...

PS: There is a road to the west, and neighbors will be on the other sides. To the south, we are allowed by the building authority to fill up to 1 m (3 feet 3 inches), possibly with retaining walls according to the contractor. A basement will not be built.

I wouldn’t worry about the street; it clearly slopes downward to the south.

Ask the planner why this height was chosen. If there is no reasonable explanation, I would go one step (17cm (7 inches)) higher, even though I don’t see any major issues with the current height.

That sounds good. So let's put aside the rainwater coming from the street. But what about the rainwater falling on our paved parking spaces? Shouldn't that flow toward our house, or am I mistaken?

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

The site has a north-south slope, which the planner averaged out to avoid having to add too much fill on the south side. That costs money. As a result, the northwest corner is about 0.4 m (16 inches) above the house level, while the southwest corner is roughly the same amount below the house level. For the parking area, you need good drainage, or what I would do is build it using gravel with granite chippings, Rhine pebbles, or similar material on top, which works very well and absorbs a fair amount of water. Try to minimize the use of retaining walls; do as much as possible with earth instead, since these walls are expensive and can easily reduce the usability of the property. Karsten
