Professional services are sought to update, develop and deliver coastal flood hazard zone (CFHZ) assessments for Northland.

The recent acquisition of LiDAR data has made it possible to undertake bathtub modelling of the Northland coastline. The main objectives of this project are to define water levels around the coastline including mean high water springs and a number of different storm surge scenarios including but not limited to 0.2%, 1% and 2% AEP. Sea sea level rise scenarios will then be mapped in 0.1m increments on top of these levels and translated as hazard lines. A limited number of these scenarios will be published by NRC as regulatory maps, with others used in sea level rise assessment tools.

It is expected that the coastal flood hazard zone assessments will be undertaken in accordance with good practice, consistent with the methodology used in the 2016 Tonkin and Taylor report “Coastal Flood Hazard Zones for Select Northland Sites”, and in general accordance with the guidance of the 2017 MfE ‘Coastal Hazards and Climate Change: a guide for local government’.

Coastal flood hazard zone assessments and mapping will be carried out along the entire coastline of Northland, with the exception of the Awanui and Kaipara harbours, where hydrodynamic modelling has been, or will be undertaken in the near future.
Wave set-up will be assessed on open coasts, sheltered coasts and harbours. Wave run-up will be assessed on open coasts only.

The tender will close at 4pm on 16th January 2020. We expect the project to be completed before 1st May 2020.

This tender has been awarded.
