Correct, that is probably the simplest solution: let the terrain fall away with a 2% slope around the house before the terrain rises again, possibly collect water in a channel and drain it into the downspouts. In a hillside location you will need various slopes and retaining walls anyway. But all that belongs to the landscaping and is not part of a house construction contract.I don't quite understand the problem yet. The planner said that only a small portion of the terrain in the rear area has to be excavated. But the fact that something had to be excavated was clear from the outset. What is a small portion? Excavating 20 to 70 cm is small to me?
Assuming your house is at 0.00 and the neighbor is at 0.60. I would immediately slope the neighbor's side down to -0.10 or -0.20 and then slowly let it rise back to 0.00 toward the house. Where is the problem?
For other neighbors at 0.20 just slope down to -0.20 and then slowly rise back to 0.00.
That neighbors are not allowed to drain onto your property is also not correct. If it is given by the natural terrain slope, then that is completely legal.
But nothing has to flow toward the house. In general, it is always correct to build with a slope of at least 1-2% away from the house in all directions. Not just the terrace. That is stated, for example, in the guidelines and technical information of the plaster/insulation manufacturers.
