Seven legacy systems were migrated to Auckland Council’s GIS environment where the creation of new assets and maintenance of existing assets are now being undertaken. Using asbuilts sent to the stormwater team from development engineers and/or internal projects, the geometry and attributes of stormwater assets are captured using standard ArcGIS editing functionality. Whilst due care has been taken to capture the assets as accurately as possible, the data is indicative and cannot be considered to align to any particular boundaries or features including cadastral.

The Stormwater Management Area-flow overlay aims to protect Auckland's aquatic biodiversity. Auckland has numerous small and narrow streams. Despite their small size, these streams are home to much of our aquatic biodiversity. This biodiversity is threatened by the effects of ongoing urban development. The creation of impervious surfaces in a catchment undergoing development increases the rate and volume of stormwater runoff. This change in hydrology, unless managed, can have a significant adverse effect on streams within the catchment. Increased flows and stormwater volumes can accelerate stream erosion, particularly in steeper upper catchment areas, and can create hydrological conditions that do not support healthy aquatic ecosystems. In developed urban catchments with large areas of impervious surface, increased runoff is one of the primary causes of degraded stream health. However, in areas yet to be developed, or with existing development at low levels, development can be enabled while also protecting and enhancing in-stream biodiversity and other stream values, reducing and managing stormwater runoff, and other measures such as enhancing riparian margins. High-value, and potential value, streams at risk or particularly susceptible to the effects from development have been identified and their contributing catchment areas mapped (stormwater management area: flow (SMAF)). Future development and redevelopment in these catchments will be subject to controls to manage stormwater runoff to enable development, while at the same time protecting Auckland’s aquatic biodiversity from further decline.

Purpose:The coastal inundation hazard layers map describes the areas exposed to extreme water levels caused by storm tides, wave setup and sea-level rise under the following scenarios (where AEP is the Annual Exceedance Probability or the chance of occurring each year, ARI is the Average Recurrence Interval):20% AEP (5 year return)5% AEP (20 year return)2% AEP (50 year return)1% AEP (100 year return): to demonstrate present day risk in alignment with the Auckland Unitary Plan activity controls2% AEP (50 year return) + 1m sea level rise2% AEP (50 year return) + 2m sea level rise1% AEP (100 year return) + 1m sea level rise: in alignment with Auckland Unitary Plan activity controls1% AEP (100 year return) + 2m sea level rise: to demonstrate longer term risk with ongoing sea-level riseThis is a generalised version of the data. Download the original full dataset with layer files here:https://data-aucklandcouncil.opendata.arcgis.com/datasets/coastal-inundation-hazards-geodatabase/aboutThe layer takes into account extreme sea levels calculated between 2013 and 2019, as compiled in Carpenter, N., R Roberts and P Klinac (2020). Auckland’s exposure to coastal inundation by storm-tides and waves. Auckland Council technical report, TR2020/24. Auckland’s exposure to coastal inundation by storm-tides and waves (knowledgeauckland.org.nz)Sea-level rise values applied currently align with the projections by the Intergovernmental Panel on Climate Change sixth assessment report (2021), and the Ministry for the Environment (2022) Interim guidance on the use of new sea-level rise projections, which updates the Ministry for the Environment Coastal Hazards and Climate Change Guidance for Local Government (2017). In MfE’s (2022) Interim guidance, (excluding vertical land movement) one metre sea-level rise is projected to occur between 2095 - >2200, depending on the emission scenario used. Two metre sea-level rise is projected to occur in the longer term (beyond 2150). MfE’s (2022) Interim guidance recommends the inclusion of vertical land movement (VLM) in relative sea level rise considerations. These are not included in the above sea level rise predictions due to the high VLM variability across the region. Vertical land movement is generally predicted to increase the rates of relative sea level rise for the Auckland region so should also be incorporated in planning and design.Refer to Interim guidance on the use of new sea-level rise projections | Ministry for the Environment for more information on MfE’s interim guidance on sea level rise and vertical land movement.Lineage:3Extreme sea levels for the Auckland region were derived by NIWA in 2013 (Part 1 of Technical Report 2020/24). From 2016-2019, additional extreme sea level data was gathered for:The east coast estuaries (NIWA, 2016; Part 2 of Technical Report 2020/24)Parakai/Helensville Harbour (DHI, 2019; Part 3 of Technical Report 2020/24)Great Barrier Island (NIWA, 2019; Part 4 of Technical Report 2020/24)In 2020, these levels were projected onto the land topography (derived from the 2016-2018 LiDAR survey) by Stantec to establish the extent of coastal flooding.

Auckland Urban Heat Assessment provides a highly detailed map of how temperatures vary across Auckland and the factors influencing these temperatures. Temperature predictions were generated using climate modelling tools, data from local climate monitoring stations, high resolution land cover data, and census data. The dataset was generated over a five-month period from 1stNovember 2021 to 31stMarch 2022, which coincided with Auckland's hottest summer on record.The datasets are useful to support communication on heat-related hazards and to inform decision making and planning for future heat impacts. The data is also useful to find synergies in heat and carbon mitigation solutions and to inform climate change risk assessment for Auckland.Further details on methods and findings are available in the technical report on Knowledge Auckland:https://www.knowledgeauckland.org.nz/publications/auckland-uban-heat-assessment-technical-report/The Urban Heat Datasets were produced for Auckland Council by Arup New Zealand Limited.Creation Date: October 2024Update Cycle: AdhocContact Person:Ayushi KachharaSenior Climate Analyst, Chief Sustainability OfficeAuckland Council

The Future Development Strategy (FDS) is Auckland’s long-term approach to growth and development. It sets out how Auckland will grow and change over the next 30 years.The FDS is a key planning tool to identify strategic priorities for the coordination and alignment of the council’s infrastructure planning and investment decisions with the timing and sequencing of growth.Future urban areas are new greenfield areas which are developing or are yet to be established on the fringe of the existing urban area, and in rural and coastal settlements.The FDS identifies the sequencing and timing of future urban land for development readiness over 30 years. Development readiness is linked to infrastructure prerequisites - key bulk infrastructure which development connects to or relies on, such as transport, water, wastewater and stormwater networks. This layer is intended to be viewed at a regional scale, not to show information at the individual property level. In future urban areas, areas indicate the council’s high level, strategic approach to greenfield growth. Boundaries shown are indicative only. Any changes to zoning at the individual property level will be determined through a plan change process. and shown on the Auckland Unitary Plan maps.Further information about the Future Development Strategy is available here.

The Auckland region has a high exposure to coastal hazards including coastal instability and erosion. These hazards can present a safety risk, adversely affect property and infrastructure, and damage or destroy cultural and environmental sites. A programme of research has been undertaken to identify, at a regional level, the Area Susceptible to Coastal Instability and/or Erosion (ASCIE). ASCIE is the area landward of the current coastline that is at risk because of coastal erosion or instability caused by coastal erosion. The study forecasts the areas of Auckland’s coastline that could be affected by coastal erosion and instability under a range of climate change (sea-level rise) scenarios and timeframes.This data is mapped at a 0.5 km to 5.0 km scale and is not intended for site-specific use other than to determine whether more detailed study is warranted. Due to the large scale of the assessment (i.e., 0.5-5 km resolution) errors are inherently introduced due to the variance within a coastal cell. To identify areas that could potentially be susceptible to coastal instability and/or erosion typical upper bound values have been adopted for each coastal cell. This means that in some areas the ASCIE may be overpredicted (i.e., shown further landward). However, this also means that in ASCIE may be underpredicted in areas where values are larger than the typical upper bound value (i.e., the largest or maximum values). Therefore, this assessment isrecommended to be used as a preliminary tool. The regional-scale ASCIE can be refined by undertaking an assessment on a more detailed scale.https://www.knowledgeauckland.org.nz/publications/predicting-auckland-s-exposure-to-coastal-instability-and-erosion/The regional-scale assessment of ASCIE is based on available data and tools and understanding ofcoastal processes. Uncertainty may be introduced to the assessment by:an incomplete understanding of the parameters influencing the areas susceptible to coastal instability and/or erosionan imprecise description of the natural processes affecting, and the subsequent quantification of each individual parametererrors introduced in the collection and processing of datascale of assessment and variance in the processes occurring within individual coastal cellsother hazards such as land based geotechnical instability, or planning and landscape impacts etc. that are not accounted for within the ASCIEadopted methodologiesTerms and Conditions:You are permitted to use this website and any data, maps, plans, content and information ("information") provided by this website, on the following terms and conditions: The website and the information provided in it are the copyright of Auckland Council.

It is not intended for site specific use. To identify areas that could potentially be susceptible to coastal instability and/or erosion (ASCIE), typical upper bound values have been adopted for each coastal cell.

Therefore, this assessment is recommended to be used as a preliminary tool. The information presented relates to potential future coastal erosion, and the land instability caused by this erosion. There are other hazards that are not presented here, such as coastal inundation and tsunami. See the Auckland Hazard Viewer for these other hazards: here This ASCIE mapping should not be used for the assessment of the erosion susceptibility of individual properties. As a 'first-pass' assessment it may include significant inaccuracies at localised levels. Assessment of individual properties (e.g. for consenting, valuation and insurance purposes) should be based on a site-specific (Level C) assessment prepared by a suitably qualified and experienced practitioner. The lines shown on these maps do not show the future position of the coast. Rather, they show the area that might become unstable as a result of a smaller area of coastal erosion.

Topicality: 01-01-2025Projection: New Zealand Transverse Mercator (NZTM)This layer contains the archive of the Territorial Authority and Local Board boundaries maintained by Stats NZ.This dataset is a derived version comprising local boards for Auckland and territorial authorities for the rest of New Zealand, as defined by the territorial authorities and/or Local Government Commission and maintained by Stats NZ(the custodian), clipped to the coastline. This clipped version has been created for map creation/cartographic purposes and so does not fully represent the official full extent boundaries.For statistical outputs that use territorial authorities to aggregate and report data Auckland Council is treated as a single geographic entity. This can hide meaningful patterns and trends for a significant portion of the population. A solution was to create a new classification of territorial authorities that includes the local boards for Auckland. The Auckland Council was established in 2010 under the Local Government (Tamaki Makaurau Reorganisation) Act 2009. Seven territorial authorities within the Auckland Region were abolished and replaced by the unitary authority Auckland Council. Local boards fall within the community board classificationThis layer get updated yearly with the latest boundary data. You can use this layer when you need any year of boundary data in your map. By setting a filter on the dataset year you can filter on specific year of the dataset.For information about the fields in this dataset go to the Data tab.The layer is further generalised by Eagle Technology for improved performance on the web, therefore it doesn't fully represent the official boundaries.If you only need the latest boundary data in your map you can use the current version of this dataset.

This provides a polygon coastline and islands layer which is based on the Topo50 products. It is a combination of the following layers:

• NZ Coastlines (Topo 1:50k)
• NZ Island Polygons (Topo 1:50k)
• NZ Auckland Is Island Polygons (Topo, 1:50k)
• NZ Campbell Is / Motu Ihupuku Island Polygons (Topo, 1:50k)
• NZ Antipodes Is Island Polygons (Topo, 1:25k)
• NZ Kermadec Is Island Polygons (Topo, 1:25k)
• NZ Bounty Is Island Polygons (Topo, 1:25k)
• NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k)
• NZ Chatham Is island polygons (Topo, 1:50k)

This topographic coastline is the line forming the boundary between the land and sea, defined by mean high water.

Islands from the NZ Island Polygons layer that lie within the NZ Coastline and Chatham Islands areas (i.e. islands in lakes, rivers and estuaries) have been removed.

The GIS workflow to create the layer is:

1. NZ Coastlines were converted from a polyline to a polygon using a polyline to polygon tool.
2. The resulting coastal polygon was then used as an input into an erase tool and run against the NZ Island Polygon layer to remove all islands lying within the NZ Mainland and Stewart Island.
3. This was then merged with the NZ Chatham Is island polygons (Topo, 1:50k) that have had the islands within the main island polygon removed, NZ Auckland Is Island Polygons (Topo, 1:50k), NZ Campbell Is / Motu Ihupuku Island, NZ Antipodes Is Island Polygons (Topo, 1:25k), NZ Kermadec Is Island Polygons (Topo, 1:25k), NZ Bounty Is Island Polygons (Topo, 1:25k) and NZ Snares Is / Tini Heke Island Polygons (Topo, 1:25k) layers using a merge tool.
