10.1.3.1
Streets (other than type 2 Streets for Motorways) must be split at the external boundary of the Local Highway Authority administrative area. For further information about recording Motorways, see Section 7.
10.1.3.2
Streets within a Local Highway Authority must not be split at internal administrative boundaries, except at District Council administrative boundaries in a two-tier government structure. Streets must not be split at parish, wards or other internal administrative boundaries – these should be regarded as “soft” boundaries.
10.1.3.3
If a Street passes from one TOWN_NAME to another there must be separate Street Data for each TOWN_NAME. The separation must be at a point approximate to the boundary.
10.1.3.4
Typically, this means splitting the Street at a junction close to the boundary. The TOWN_NAME is normally that in which the major length of the Street is.
10.1.3.5
A location is described as a TOWN_NAME or as a combination of TOWN_NAME and LOCALITY. LOCALITY must be used only if it is necessary to distinguish between two Streets of the same name within the same town. Acceptable exceptions to this rule are identified below.
10.1.3.6
Punctuation must only be included within the TOWN_NAME and LOCALITY if the punctuation is part of the official TOWN_NAME and LOCALITY, for example “Stoke-on-Trent”. Ampersands must only be used as a replacement for the word “and” if it appears in the official version of the name of a town, locality or Street. Full stops or commas must not be used as part of any TOWN_NAME and LOCALITY.
10.1.3.7
The Attribute name TOWN_NAME can be misleading particularly in sparsely populated areas. It must be populated with one of the following geographical identifiers, where continuity of the TOWN_NAME can be achieved for the Street Name or Street Description:
- The name of a city.
- The name of a town.
- The name of a village.
- The name of a hamlet.
- The name of a parish.
- A recognised settlement name.
- A geographical identifier.
10.1.3.8
The TOWN_NAME therefore represents one of the above and not the post town allocated by Royal Mail, although they are often the same name.
10.1.3.9
A TOWN_NAME must always be recorded for a type 1 and a type 2 Street and may be recorded for a type 3 and a type 4 Street.
10.1.3.10
LOCALITY defines an area or geographical identifier within a town, village or hamlet that must be a recognised geographical name.
10.1.3.11
LOCALITY must only be used for Streets in the following scenarios:
- If there is more than one Street of the same name in the same town.
- If the inclusion of a locality is necessary in addition to TOWN_NAME to avoid ambiguity in the identification of that Street and there is evidence of a recognised geographical identifier.
- If a settlement, with its own settlement name in common use, is in the same parish as another settlement but is distinctly separate, particularly in sparsely populated areas.
- If a site contains named Streets and the site name is included in the Postal Address, for example airports, out of town shopping centres, industrial estates. This allows for Postal Addresses to be constructed which are meaningful to users.
- If the Street falls within a London Borough, apply the following rules. For a map of the London Boroughs, see Appendix C.
- For all Streets within Inner London Boroughs the TOWN_NAME must be recorded as ‘London’ and an appropriate locality must be added to each Street. This applies to:
- Camden.
- City of London.
- Hackney.
- Haringey.
- Hammersmith & Fulham.
- Islington.
- Kensington & Chelsea.
- Lambeth.
- Lewisham.
- Southwark.
- Tower Hamlets.
- Wandsworth.
- City of Westminster.
- For all Streets within Outer London Boroughs the appropriate local description for the town must be used, for example Wimbledon, Enfield, Harrow etc. and the Locality only used to avoid ambiguity within that ‘Town’.
- Outer London Boroughs must reach agreement as to how this Field is populated consistently across London Boroughs to avoid duplication. This applies to:
- Barking and Dagenham
- Barnet.
- Bexley.
- Brent.
- Bromley.
- Croydon.
- Ealing.
- Enfield.
- Greenwich.
- Harrow.
- Havering.
- Hillingdon.
- Hounslow.
- Kingston upon Thames.
- Merton.
- Newham.
- Redbridge.
- Richmond upon Thames.
- Sutton.
- Waltham Forest.
- For all Streets within Inner London Boroughs the TOWN_NAME must be recorded as ‘London’ and an appropriate locality must be added to each Street. This applies to:
