Resilient River Communities

Tawaha floodway sill, Site No. 10

Region:
Council:
Greater Wellington

Project Start Year: 2025

This project is one of 16 being carried out across South Wairarapa and Kapiti.  The work will see the upgrade of the Tawaha floodway sill which feeds/controls the overflows from the Ruamāhanga River, thereby upholding community flood resilience. It will involve a combination of rock protection and realignment of sills on the Waiohine River as well as vegetation removal, surveying and levelling. ​

Benefits: Each project aims to deliver improved climate resilience and safety outcomes for the community, businesses and industry  and infrastructure caused by repeated river flooding and erosion at an overall reduced cost to ratepayers​

Adaptation: Ecosystems and biodiversity will improve by providing more space for river channels. This will lead to a more diverse aquatic and riparian habitat, better connections between terrestrial and aquatic ecosystems and improved safety outcomes for nearby homes and facilities. ​

Resilience: Continued flood hazard management and erosion protection for land using sustainable management approaches enhance flood resilience in the area. ​

Collaboration: The work is co-funded by Greater Wellington and central government through Kānoa’s Regional Infrastructure Fund and provides the opportunity for mana whenua to be actively involved in decision-making and mātāwaka to be working on the ground, as well as upskilling and developing professionally. ​

Greater Wellington’s purpose is to enrich life in the Wellington region by building resilient, connected and prosperous communities, protecting and enhancing our natural assets and instilling pride in what makes us unique. ​
