Identifies the Waitakere Ranges Heritage Area as described by the Waitakere Ranges Heritage Area Act 2008.

The purpose of water supply management areas is to provide for the ongoing operation, maintenance, upgrading and development of the municipal water supply infrastructure. The areas comprise the catchments that are mainly in public ownership surrounding municipal water supply infrastructure. This infrastructure includes five dams in the Waitakere Ranges,...

Identifies the Wetland Management Areas as set out within the policy framework of D8 Wetland Management Areas Overlay and Schedule 1 Wetland Management Areas Schedule of the Plan.

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-...

This dataset includes geotechnical reports available throughout Auckland Council systems. Geotechnical reports are written by suitably qualified and experienced geotechnical engineers or engineering geologists and include information on ground quality and subsurface geology. They are generally undertaken for infrastructure and building development or land...

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...

The high water levels are provided for a range of Average Recurrence Interval (ARI) events. Average recurrence interval is often referred to as a return period. These can be approximately converted to Annual Exceedance Probability (AEP), the probability of occurrence each year, by the following conversion table:ARI (yr)AEP (%)25052010102055021001The high...

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...
