Stormwater flooding hazard information

Why NPDC is publishing this data

 

NPDC is sharing information about flooding risk to:

  • Help the community understand natural hazards and prepare for potential emergencies caused by extreme weather.
  • Establish the limitations to development and construction of buildings on areas that are affected by flooding hazards, affecting District Plan conditions.

The Resource Management Act 1991 makes NPDC responsible for controlling any effects of the use, development or protection of land to avoid or mitigate natural hazards. Our stormwater discharge consent also requires us to avoid or minimise adverse flooding of land and property. Mapping flood hazards helps us fulfil these requirements.

NPDC’s FLOOD VIEWER is an interactive tool to share the data about flooding hazard that council has available. The tool is a map where you can look at the flooding risk district wide and search for a specific address to view details.
