Does trenching belong to property management?

The key is where this ditch is, what is the purpose of digging this ditch, whether it was dug by the municipal government or the construction team of the developer or property company.

Unclear and uncertain.

Of course, if this ditch blocks the road and there are no aisles and tips, the property company is negligent.

If the ditch is not completely blocked and there is still an aisle, you can drive in by yourself if you are prompted. That is a problem of driving by yourself.
