Land and Water Regional Plan Canterbury A3 map series grid.

During the mid to late 19th century, the Canterbury region was systematically surveyed. The maps produced through this effort are often referred to as the ‘red’ and ‘black’ maps and they typically record a pre-European, less-modified landscape. For convenience they are referred to here as the Black Maps. The Black Maps show the extent of wetlands and the locations of rivers and streams before they were modified.

Paper copies of the original Black Maps were recently transferred to Archives New Zealand. Te Rūnanga o Ngāi Tahu has taken a close interest in leading the preservation of this resource, investing significant cost and effort. Environment Canterbury is working on a cross-agency project with Te Rūnanga o Ngāi Tahu, Archives New Zealand and Micrographics to digitise the maps in order to make them more accessible he public. As maps are scanned and become available, the botanical, pedological and hydrological features are captured spatially and put on Canterbury Maps.

Enlarged Main Navigation Channel as defined in the Lyttelton Port Recovery Plan.

The Lyttelton Port Recovery Plan provides for the repair, rebuild and reconfiguration of Lyttelton Port and the redevelopment of Dampier Bay. It also establishes how transport issues and construction effects will be managed, and directs Environment Canterbury, Te Hapū o Ngāti Wheke, Te Rūnanga o Ngāi Tahu, Christchurch City Council and LPC to work together to develop a management plan to improve the health of Whakaraupō/Lyttelton Harbour and its catchment. The Lyttelton Port Recovery Plan directs amendments to the following district and regional planning documents to enable the Port's recovery: 1. Canterbury Regional Policy Statement 2013; 2. Regional Coastal Environment Plan for the Canterbury Region; 3. Proposed Christchurch Replacement District Plan; 4. Canterbury Land and Water Regional Plan; 5. Proposed Canterbury Air Regional Plan. These amendments are set out in the Appendices 1 to 5 of the Recovery Plan.

Protected Recreational, Cultural or Historic Sites as represented by areas in map series 2 of the Canterbury Regional Coastal Environmnet Plan (RCEP) 2005.

Schedule 5 (Definitions of Areas and Sites) of the RCEP defines these areas in detail.

Northern Fan FMU as shown in the proposed Plan Change 5 to the Land & Water Regional Plan.

The proposed changes seek to deal with the management of the effects of land uses, particularly farming activities, on water quality throughout the Canterbury region and the management of water quality in the Waitaki sub-region, and flows in Whitneys Creek. Proposed Plan Change 5 comprises two parts. Part A consists of provisions which apply throughout the Canterbury region Part B consists of provisions that apply to the Waitaki sub-region only, and is proposed to be inserted as "Section 15B Waitaki Sub-region" into Section 15 of the Canterbury Land and Water Regional Plan.

Coastal Water Quality Areas as shwon in Map Series 1 in the Canterbury Regional Coastal Environment Plan (RCEP) 2005.

Areas as defined in Schedule 5 (Definitions of Areas and Sites) of the RCEP.

Each unit in the layers is classified for management in accordance with the following classes: (i) Class Coastal AE waters (being water managed for the maintenance of aquatic ecosystems). (ii) Class Coastal CR waters (being water managed for contact recreation and the maintenance of aquatic ecosystems). (iii) Class Coastal SG waters (being water managed for shellfish gathering, contact recreation and the maintenance of aquatic ecosystems).

Groundwater level or piezometric surveys are a snapshot of water levels in wells (and sometimes springs and rivers) in an area at a point in time. The measurements are used to create contours of equal height above sea level, similar to topographic contours, which we call ‘piezometric contours’. Groundwater flow is perpendicular to these contours at a regional scale.Proposed disclaimer/additional information in Canterbury MapsGroundwater level or piezometric surveys are a snapshot of water levels in wells (and sometimes springs and rivers) in an area at a point in time. The measurements are used to create contours of equal height above sea level, similar to topographic contours, which we call ‘piezometric contours’. Groundwater will flow perpendicular to these contours.In using these datasets, please consider:·
What scale are you interested in? Local flow paths can be very different to regional flow paths due to changes in local-scale permeability and recharge sources. Most of our contours are regional scale, and may only provide an indication of potential local flow paths. You may need to conduct your own measurements of a site to better determine local flow paths.·
When was the survey undertaken? If the survey is older, it may be that local groundwater conditions have changed. There may be more than one survey of an area, and at more than one time of the year. Groundwater contours and hence flow direction can be different at times of lower and higher groundwater levels, and can depend on external factors such as stream flow and irrigation schemes.·
How many wells were measured to create the contours? Contours are more reliable in areas where more wells were measured. Most of the contours have associated layers showing the wells used to create them, which may be consulted to determine local-scale reliability.
