10.3.2.1
Administrative boundaries must be captured using the latest version of Ordnance Survey MasterMap® Topography Layer mapping data, although other mapping products, including paper maps can be used as reference or investigation material.
10.3.2.2
To achieve consistency of Street geometry between Local Highway Authorities, Streets that cross Local Highway Authority administrative boundaries must align at the boundary. This requires Authority Street Custodians from both adjacent authorities to work closely with each other to ensure that:
- ESUs crossing administrative boundaries are coincident and match across the boundary.
- Interest Records are recorded on each other’s Streets.
- ASD coordinate Records are coincident and match across the boundary.
