The Fault Awareness Overlay indicates areas where deformation of the ground may occur due to fault rupture, however in these areas the fault is poorly defined and there is significant uncertainty regarding the specific fault location. This uncertainty is often due to the fault being buried beneath overlying soil, thick alluvium, or landslides, where no surface expression of the fault is observable on the ground surface, or where small-scale geological maps are the only available evidence of the fault’s location. Fault rupture and deformation of land in the Fault Awareness Overlay can also cause significant damage to buildings and infrastructure, and harm to people.

The Fault Deformation Overlay indicates where deformation of the ground may occur due to fault rupture. The ‘fault zone’ lies within the Fault Deformation Overlay and is the area where deformation of the ground is likely to occur. Fault rupture and deformation of land can cause significant damage to buildings and infrastructure, and harm to people.

The Fault Hazard Overlay is based on the best information available to the Council at the time the Plan was notified. The Overlay contains those known fault traces considered to be active or potentially active. It is anticipated that as development continues within Fault Hazard Overlay areas, that the precise location of fault traces will become better known. Those purchasing or contemplating development of properties located within the Fault Hazard Overlay should obtain the most up to date information held by the Council regarding the precise location of fault traces prior to proceeding. The Overlay indicates areas within which the fault traces are thought to lie. Because most fault traces have not been accurately mapped, an area wider than that which could be affected by any fault rapture has been indicated (the mapped areas are generally 150m wide). It is anticipated that as a better understanding of the risks and location of fault traces is obtained, the extent of the overlay may be reduced by plan changes in the future.

Indicates areas in the residential areas of Glenduan and Todds Valley, Rural Zone and Conservation Zone where land may be subject to flooding or hazards caused by running water such as debris flows on stream fans and the change in the position of creeks, but insufficient information is available to allocate it to the Inundation Overlay or Flood Paths Overlay.
The Flood Overlay is an advisory overlay which is given effect to through other rules in the Plan, the Resource Management Act itself or through other legislation. Examples of situations where the Flood Overlay will be taken into account include the earthworks rules of the Plan which make earthworks within the Flood Overlay a restricted discretionary activity, section 14 of the Resource Management Act which controls the damming or diversion of water, and the Building Act which takes flood hazards into account when assessing a building consent.

Indicates areas where the land may be subject to occasional flooding within Flood Paths and overflow channels of rivers and streams. The overlay is based on historic observed data. These areas have been differentiated from the Inundation Overlay because of the higher risks to safety and property associated with this type of hazard, particularly from the erosive or destructive force of moving floodwater. The Council is undertaking a long term programme of upgrading storm water drainage. As this work progresses the susceptibility of areas to flooding will change. Those purchasing or developing within the Flood Path Overlays should obtain the most up to date information available from the Council.
As part of the preparation of Plan Change 29, the Flood Path Overlay was reviewed and where modelled flood hazard (river and stream) existed for the Residential, Inner City, Suburban Commercial and Industrial zones, data from the Flood Path Overlay was deleted and replaced with the Floodway Overlay. The Flood Path Overlay data affecting the Open Space and Recreation, Rural and Conservation zones was not reviewed and consequently has not been amended.

The Inundation Overlay indicates areas which may be susceptible to localised stormwater flows, stormwater ponding, ponding of other floodwaters or tidal inundation. The overlay is based on historic observed data. The causes of localised ponding are highly site specific but generally relate to the presence of a low lying area where stormwater accumulates or tidal backwater effects prevent drainage.
Tidal inundation may occur at some sites during periods of extra high tides and particularly in combination with low pressure weather systems. In exposed coastal areas wave action is also a factor.
As part of the preparation of Plan Change 29, the Inundation Overlay was reviewed and where modelled flood hazard (river and stream) existed for the Residential, Inner City, Suburban Commercial and Industrial zones, data from the Inundation Overlay was deleted and replaced with either the High Flood Hazard or Flood Hazard Overlay. The Inundation overlay data affecting the Open Space and Recreation, Rural and Conservation zones was not reviewed and consequently has not been amended.

The High Flood Hazard Overlay identifies areas where flooding in the 1% AEP event at 2130 is greater than or equal to 0.3m deep and/or velocity is equal to or more than 2m/s.

Liquefaction occurs when strong ground shaking, such as during an earthquake, causes loose and saturated sediments to lose strength and behave as a fluid. Liquefaction may cause ejection of liquefied material and groundwater, differential settlement of the ground surface and cracking of the ground surface associated with lateral spread. Structures founded on soils that have liquefied may experience bearing failure, differential settlement, and/or large horizontal displacements. Buoyant structures buried in liquefied soils such as tanks, pipes and manholes, may rise to the surface.
The Liquefaction Hazard Overlay indicates areas where liquefaction-induced ground damage is possible in a strong earthquake.

Some activities are located in zones where they do not comply with the ordinary zone standards. An example is a service station in the Residential Zone. Confinement to commercial areas would not allow the necessary distribution of such services across all areas of the city. These activities are provided for by scheduling and regulating them especially on their identified site. The intention of this is to ensure the continuation of a service to the community and protect the investment committed to buildings and site development. Opportunity to expand on site may be provided for such activities, which is a more liberal regime than existing use rights provided for under section 10 of the Resource Management Act.
Schedules are also used in the Open Space and Recreation Zone to indicate permitted activities in different classes of land within that zone.
The rules that apply to the activity and site are stated in the relevant schedule. The schedules are located after the rule table in the relevant zone. The relationship between the schedule and the rule table is set out within each schedule.

The pattern of land use in the District that has developed over time reflects the physical characteristics of the land and other resources, people’s preferences from time to time, and planning decisions under former legislation. There are now easily identifiable areas of the District with distinctive environmental qualities. At the broadest level these can be defined in terms of landscape:
the remote undeveloped backdrop to the District (the Conservation Zone).
rural land, which is largely used for pastoral farming and exotic forestry.
the urban or built up area.
Within the built up area, historical patterns of development have led to areas with characteristics which are clearly residential, commercial, industrial or open space and recreational. Infrastructure, including roads, drains, water supply and other services, has been developed to reflect the needs of this existing pattern. Each distinct area, together with its infrastructure, represents a resource that is required to be sustainably managed under this Plan. Different sets of issues arise in the different areas and need to be addressed differently in the Plan.
The Plan recognises that areas have distinctive environmental characteristics, and what effects of activities are acceptable may differ between areas. The Plan applies a zoning approach to define the different environmental qualities sought for different areas and to control the actual and potential adverse effects of development within them.
The zones contain all of the land area of the District above mean high water springs. The Coastal Marine Area, although not called a zone, is dealt with in this Plan as a similar geographical unit. The issues affecting the Coastal Marine Area and the dry land area of the District are often related. This Plan takes an integrated approach to these, particularly by means of the Coastal Environment Overlay.
