How should these points be understood in the development plan?

Hello,

maybe you can help me again this time. I have already spoken with the building authority, but the caseworker seemed to have a bad day and was not very willing to explain it to me, or maybe I’m just too stupid to understand...

we want to start planning our outdoor areas. we border three neighbors and the sidewalk.
Neighbor 1 is somewhat lower (40cm), neighbor 2 somewhat higher (70-80cm), neighbor 3 significantly higher (120cm and more) and the sidewalk lower (60cm).

basically, whoever digs out or fills in has to stabilize it, right? but I guess we will come to an agreement...

what matters to me now is what is actually allowed according to the development plan.
As far as I understood the caseworker, you can do whatever you want within the property, but then I don’t understand the part about "raised terraces and steep slopes". when is a terrace considered raised and when is a slope steep?
I was told walls are only allowed up to 20cm high, and may be made of natural stone (but only 20cm high as well). When I read the corresponding part of the development plan, I understand it as saying that base walls of fences may only be 20cm high, but natural stone walls are allowed??? how are you supposed to compensate for the height differences then?
Fences max. 120cm high from the top edge of the natural ground? then neighbor 3 wouldn’t be allowed to build a fence at all because with the fill it’s already over 120cm.

by the way, the maximum height of the finished ground floor floor level (EFOK) was prescribed.

thank you very much and happy Easter!

In the second picture, I think an important part is cut off. At 1.9.1 it says at the end: the height differences to the edge of the road or the adjacent properties must be overcome by a slope on the own property. Wouldn't that then mean that no walls for support are allowed? At least at the borders? Not even the 20cm??? Are planting rings a slope?

For fencing, you may only use fences; however, these fences do not have to extend all the way to the ground, but may be walls in the bottom 20 cm. Dry stone walls may enclose a terrain model at full height, but this is limited to the plot-specific EFOK. At the boundary, you must have returned to the original level, and it must be sloped – not a steep slope. Slopes are "roof slope" ground profiles. Using planting rings in this context is not excluded. You should not use welded mesh panels and the neighbor picket fence or vice versa.

At 1.9.1 it says at the end:
the height differences to the edge of the roadway or the neighboring properties must be overcome by a slope on the own property.

This is how it was also stated in our development plan: Retaining walls, whether high or low, are prohibited. If a height difference exists, the higher neighbor must create a slope of max. 30 degrees on their own property, meaning 30 cm in height per meter. Thus, one must "sacrifice" 2 meters of their property at the relevant boundary if they want to correct 60 cm.
Most have then also carried out hedge planting in this section. There was no re-measurement later.

That would mean that no walls for support are allowed at all? At least not at the boundaries? Not even 20 cm???
Are planting rings a slope?

Since the 30 cm relates to our area, I would say that with planting rings you can of course make a slope. Just arrange them offset. This applies to property boundaries.

Terraces with steep slopes would be walls for me, as well as anything executed steeper than 45 degrees.
No guarantee.

Thank you very much first of all. It hasn't quite clicked with me yet though.

So, for the neighboring properties, you have to make a slope, possibly with planting rings but no form of wall whatsoever.

If I now build a wall in the front yard to have a flat level in front of the entrance, am I allowed to build a wall (Max, EFOK) with some distance from the sidewalk and have a surface at sidewalk height between the wall and the sidewalk?

if I now build a wall in the front yard to have a level area right in front of the entrance, can I then build a wall with some distance to the sidewalk (Max, EFOK) and between the wall and the sidewalk have an area at the height of the sidewalk?

From my point of view, yes. However, every "straight" section on the path between the EFOK level and the (also street-side) boundary increases the physical effort to then let the further course flow smoothly again. Height difference, slope steepness, and plateau section form a magic triangle
