The City is located on land that is geologically sensitive and partly in a coastal environment which is hydrologically dynamic. It is also located within a volcanically active region which may present localised effects.
Natural hazards are defined in the Resource Management Act. Natural hazards identified within the Tauranga City environs include, but are not limited to:
- Earthquake induced subsidence and/or flooding, including liquefaction;
- Peat deposits and other highly compressible soils;
- Erosion and land slippage associated with relic land slips and slip debris or overly steep topography;
- Flooding associated with stormwater overland flow paths and/or ponding;
- Flooding associated with sea-level rise;
- Tsunami or storm-induced flooding and coastal erosion along and within the open and harbour coastlines.
Two key pieces of legislation empower Council to manage and control natural hazards; the Resource Management Act 1991 and the Building Act 2004. Under the Resource Management Act 1991, subdivision, use and development is required to avoid, remedy or mitigate the effects of natural hazards.
The Building Act 2004 has similar responsibilities when granting building consents on land subject to specified natural hazards, with certain exceptions.
The emphasis in the management of natural hazards is to encourage people to avoid situations in which they, or their property, could be at risk.
Subdivision, use and development, and the protection of natural and physical resources contained within an area subject to, or likely to be subject to, a natural hazard are subject to the provisions in this Chapter.
