As part of the Selwyn District Plan Review, the Council has identified areas that may be at risk from coastal erosion and inundation (flooding by the sea) and developed proposed rules for how to manage that risk.

On this website you can find all relevant information on identified coastal hazards in Selwyn and how we propose to manage them in the new District Plan.

Background

Selwyn has a relatively small coastal environment with limited development opportunities, given the rural zoning of the area. The exceptions are the residential part of the coastline at Rakaia Huts, and the proposed Māori Purpose

Background

Selwyn has a relatively small coastal environment with limited development opportunities, given the rural zoning of the area. The exceptions are the residential part of the coastline at Rakaia Huts, and the proposed Māori Purpose Zone at Taumutu with the Ngāti Moki marae.

When reviewing coastal hazards as part of the Selwyn District Plan Review, we have considered the following hazards:

  • coastal inundation (flooding by the sea of low-lying coastal areas; this is particularly likely when high tides and extreme weather occur at the same time);
  • coastal erosion (where the shoreline retreats on a temporary or permanent basis); and
  • tsunami.
