Obtaining platform support - development plan

Hello everyone,
We have received a plot of land from the city. In the development plan, it says for our and neighboring plots [Erhalt Plattformen unterstuzung].
I searched a lot but could not find any information.
Can someone help?
Thanks in advance
Harry

What?!

Please provide original text excerpts and sketches/photos.

Receipt “Plattform” possible
That is how it is written
Thank you

can you not upload the corresponding document here partially redacted / censored?

I have already pondered what the OP’s native language might be, and from what - presumably in joint collaboration between google Trans later and spell check "correction" - the support of a platform to be maintained could have been distilled - so far without success.

Here is the plan
Thanks again
Harry
