I am in the building permit process and have just learned from a call to the building authority that I am located in the HQ100 EXTREM area and must take precautions against flooding, which has apparently been required in BW since 2018.
For explanation: HQ100EXTREM means that there is a dam protecting me here next to the Danube, but it could break (which is really far-fetched....) and I should implement additional flood protection, whatever that means, literally stated: "At locations in risk areas outside of flood zones for which no development plan exists, construction projects may only be built or significantly expanded in a construction method adapted to the respective flood risk according to the generally accepted rules of technology, insofar as such a construction method is technically possible according to the type and function of the facility."
I am building solidly and without a basement, I am 61cm below this theoretical extreme water level, but I do not want to raise the terrain further, which would basically be possible, just expensive and would not look good.
Now I spoke with the responsible lady by phone about whether I could build a wall around my property, which might be a possibility. She said that she did not know if such high walls are allowed there and I would also have to consider the driveway. She would recommend building 81cm higher, but if necessary 61cm higher. But I had the impression that she did not know much. Perhaps barriers could also be installed on the doors, a kind of slider, I have already seen this on the internet. Overall really annoying and none of the over 100 houses around here (built before 2018) have anything similar, there has also never been extreme flooding and I think the damage would probably be less than the investment. I also have insurance, which costs an additional €100 per year for flood coverage. I will probably install my heat pump 0.5m higher as a precaution.
Who has experience with this or a good idea on how this can be solved as cost-effectively as possible???
