The coastal environment is constantly changing as the shoreline moves and sea level varies. These natural changes become a hazard when they threaten human life and property.
Coastal erosion and coastal flooding are the main coastal hazards in our city. Coastal hazard risks will be made worse in the future as climate change leads to rising sea levels and an increased frequency of damaging or disruptive weather patterns.
We want to manage the risk from coastal hazards in Porirua and improve the resilience of our communities, now and into the future.
Porirua City Council is undertaking a full review of the District Plan. The District Plan tells us what we can and can’t do with our land. It makes rules about where we can subdivide, what activities we can do and where we can do them. For more information visit our District Plan page.
As part of this review, the government requires us to address a lot of things to keep our communities safe and to protect the local environment. This includes a requirement to identify areas that could be impacted by coastal hazards over the next 100 years, and to appropriately manage these areas.
Through robust research and consultation with the community, we want to ensure that the District Plan helps us to build resilience in Porirua to coastal hazards.
We have engaged the Focus Resource Management Group to help us to understand the coastal hazard risk in Porirua. Principal members Jim Dahm and Bronwen Gibberd have a great deal of experience with the assessment and management of coastal hazards in New Zealand, and a long history of consultation with communities.
Our coast differs across Porirua.
To understand the specific coastal environment, community values and coastal
hazards that affect particular areas we have held two rounds of community
workshops. These were undertaken in Titahi Bay, Plimmerton, Pukerua Bay,
Pauatahanui and Paremata in August and November 2018, and led by our coastal hazard
experts Jim Dahm and Bronwen Gibberd.
The first step was to build a shared understanding of the coast by hearing from the local communities about their experiences and knowledge of the coastal environment. We received a huge range of valuable information including historical photographs and observations of coastal storms and shoreline changes.
In November we ran a second round of workshops. This was our opportunity to feedback to the community on the information we had gathered as well as to present some potential hazard management options.
Titahi Bay – Coastal Hazard Presentation
Pukerua Bay – Coastal Hazards Presentation
Pauatahanui – Coastal Hazards Presentation
Paremata, Golden Gate & Browns Bay – Coastal Hazards Presentation
Please note that these presentations were prepared to provide information and outline options for coastal hazard management at community meetings in November 2018. The slides are reproduced here to encourage further community discussion and feedback.
We are keen to hear from the community about these potential management options and any other information or knowledge you have on your local coastal environment.
