Your views on transferring building act functions

The Building Act 2004 requires regional councils to control building work on large dams. This means that each regional council must perform the functions of a Building Consent Authority. To do this, a regional council needs to attain an accreditation, and due to the small number of dams in Southland, it was agreed that Otago Regional Council would gain this accreditation and manage the building consents required for dams on our behalf. They have been performing this function since 2007, but have now decided not to retain their accreditation. The new proposal outlines an agreement to transfer our Building Act functions to Environment Canterbury.

A building consent is required for all structures that meet the definition of a large dam, including flood control dams, significantly modified natural features and canals, as well as structures that form part of large dams, such as appurtenant structures. A large dam is defined in the Building Act 2004 as a dam that has a height of four or more metres and holds 20,000 or more cubic metres of water.

There have been no applications for large dams in Southland since 1992 and there are no proposals for any new large dams or to modify any existing large dams in Southland. There are currently 11 large dams in Southland – six of which are owned by Environment Southland for flood control.
