The coordinates must fall within the SNN Authority administrative area associated with the BLPU.

If the curtilage of a BLPU extent spans a SNN Authority administrative area boundary the area providing access from the Street to the BLPU in the SNN Authority is deemed to be the reference point for the BLPU using an RPC = 1. This means that the BLPU point is by the Street associated with the SNN Authority.
