permeable pavement

The discharge towards the street is not permitted and is at least controlled here in the region by the building regulations office.

ok, if they show up with a spirit level it gets more difficult. Then only infiltration is an option. Big hole in the garden, three 120 mm sewer pipes vertically into the ground. KG pipes from the drainage channel into the infiltration system. That should be sufficient.

I don't want to cause panic. But I experienced it live and in color last year because of 2.1 m² of sidewalk paved with small cobblestones! I slightly raised the middle of the path so that the water runs off to the right and left. That was enough.

Appropriate to the topic:
what do you spread in winter against ice? According to the manufacturer, salt is not allowed on permeable pavement.
Do you use regular chippings or something else? Has anyone ever used lime granulate?

Salt is not allowed on permeable paving according to the manufacturer.

Just out of interest, since this does not seem to be known to the neighbor (aside from the fact that it is prohibited here anyway): What could possibly happen?

You are not allowed to salt because it damages the soil.
permeable paving = salt in the soil.

Salt in the soil = Less weeds in the joints
