4.3.1
All SNN Authorities should integrate their SNN function with the LLPG function. During the SNN procedure, some SNN Authorities consult with many different parties before finalising the SNN details. Authority Street Custodians should also be consulted on new Street Names within the LHA area.
4.3.2
Sometimes developers request new Street Names at the earliest opportunity. It is therefore sensible that USRNs are allocated by the SNN Authority as soon as possible. This should be done in consultation with the SNN Officer, and Authority Address Custodian. It is also appropriate to consult the Authority Street Custodian at this stage.
4.3.3
The Authority Address Custodian and the SNN Officer must work closely with the Authority Street Custodian through the Authority Address Custodian to ensure all parties assign the appropriate locality, town and start and end coordinates to the Street at this stage.
4.3.4
A level 3 gazetteer must build upon this core information with the addition of ESUs and level 3 shaping vertices to define the approximate centreline of the Street. This Street geometry must be defined by the Local Highway Authority.
4.3.5
All updates must be transferred to GeoPlace monthly or as soon as possible for inclusion in the NSG and for monthly distribution to the NSG users.
