11.6.2.1
A Street is an access route to a BLPU, so the last Street used to access the BLPU should be the Street by which the property is referenced. Each ASG shall consist of a register of all Streets within a geographic area, regardless of maintenance or responsibility.
11.6.2.2
BLPUs must only be associated with a type 1, 2 or 9 Street Record.
11.6.2.3
This means that the Approved Preferred LPI of a BLPU cannot be associated with a type 3 or type 4 Street Record. However in some circumstances it is possible to associate an Alternative LPI with a type 4 Street.
11.6.2.4
If access to the BLPU can only be described via a river, canal, railway or waterway this should be recorded as a type 9 Street. In this case the Approved Preferred LPI references the type 9 Street and the BLPU must be associated with the most appropriate type 1 or type 2 Street through an Alternative LPI. The Street referenced in the Alternative LPI must be the last road or footway traversed before the type 9 Street referred to in the Approved Preferred LPI.
