Kernrechtsfrage
Whether the antenna permit could be granted without NISV calculations for the unbuilt parcel Nr. 4572J.
Extrahierter Entscheid
No. Unless it is secured that no zoned use will occur, the expected sensitive-use areas on the parcel must be included in the NISV calculation before any permit is issued.
Extrahierte Begründung
Unbuilt building-zone land must generally be treated as if the zonally permissible structures already existed; an exception requires a clearly established non-sensitive use or a proven, at least temporary, waiver of zoning-compliant development.
