Horizontal infrastructure

What is horizontal infrastructure?

Horizontal infrastructure includes roads and bridges, water pipes, sewer pipes and stormwater pipes. Horizontal infrastructure in the residential red zones can be:

  • 'In service' – temporary or permanent roads or pipes that are functioning.
  • 'In service' with a reduced level of service - this only applies to roads.
  • 'Out of service' - pipes or road that no longer function.


‘In service’ and ‘out of service’ infrastructure

Most 'in service' horizontal infrastructure in the residential red zone is there to service areas outside the residential red zone.

Horizontal infrastructure crossing the residential red zone is typically major pipes or roads that provide essential services to people in areas of Christchurch outside the residential red zones.

Some functioning infrastructure in the residential red zone continues to service occupied properties in the residential red zones.

It is not possible to build over existing pipes as they may collapse and damage the buildings and structures above them.

Some existing 'in service' infrastructure in the residential red zones could service potential future opportunities. This may make some future options easier and more cost effective. Some existing roads in the residential red zones could provide access for potential future opportunities if it was decided they are in suitable locations.

Damaged infrastructure in the residential red zones that is no longer required has been disconnected. This is to ensure infrastructure outside the residential red zones continues to work as efficiently as possible.


Removing or relocating infrastructure

Existing 'in service' infrastructure may impact upon future opportunities in some areas. Some future opportunities may need horizontal infrastructure to be moved. This can be a very expensive process and it is not always possible to move pipes or roads due to ground conditions.

Not all types of future opportunities would require the removal of existing infrastructure, for example infrastructure no longer in use that is located beneath a reserve or sports field and poses no risk.

The horizontal infrastructure maps below show fully operational, partially functioning and 'out of service' utilities and infrastructure that is owned by Christchurch City Council in the Ōtākaro/Avon River corridor, Brooklands and Southshore and required to service occupied properties in these areas, areas neighbouring the residential red zones and/or wider city networks.

This information will be updated regularly as work to replace, repair and decommission infrastructure is completed. The maps were most recently updated in December 2016.
