The Infrastructure Development Code (IDC) is the document that outlines Tauranga City Council’s and Western Bay of Plenty District Council's required standards for how infrastructure and land should be developed.
Where the City/District Plans describes what kind of structure or development is able to occur in any given area, the IDC describes the standards to which that structure or development should be constructed. It covers things like the steepest gradient you are allowed to build on and the sort of materials and methods to use when installing stormwater pipes.
