Project Background Update
Greater Wellington is developing a Floodplain Management Plan that is the culmination of many years of work and is used to understand the flood risk across the Upper Ruamahanga Valley.The development of this plan has distinct stages. Phase 1 has been completed and we are currently finalising Phase 2. You can read an overview of the first two phases below.
Phase 1 - Gathering and reviewing local information
Between 2012 and 2014 investigations into flood risk across the Upper Ruamahanga Valley were completed, this included identifying flooding and erosion problems, and collecting information about the environment and how people use and value the rivers. This culminated in a community openday to share and verify this information.
A new flood risk map was produced which used 20 years of data and well established mapping techniques. The techniques were peer reviewed by industry experts, and finally the information was released on the 22nd August 2014.

In October 2014, the GWRC project team and subcommittee started looking at ways to manage the identified flood risks which could also protect or enhance the environmental, economic, social and cultural characteristics of the floodplain.
Masterton
Greater Wellington Regional Council and Masterton District Council are carrying out work to further refine the flood risk affecting the Masterton area. Options development is currently on hold for the Masterton Urban area until this information has been confirmed.
Outside Masterton
The flooding and erosion issues are broader than than those affecting the urban area, and many rural landowners have lived with first hand knowledge of flood and erosion risks for many years.
The project team, subcommittee and landowners are working to develop management options for these rural rivers which will deliver on flood and erosion management objectives, but also protect and explore opportunities to enhance the river environment.
