What we're doing
About the Waipaoa River flood protection scheme.
The Waipaoa River Flood Control Scheme (the scheme) was designed in 1949 and was completed in 1969. It was valued by Council in 2009 at $35.7 million which excluded the 638 hectares of land owned by Council as part of the scheme.
The scheme is considered to be one of Council’s most valuable assets. It protects some 10,000 hectares of fertile floodplain land and has increased the amount of land being used for high yield horticultural purposes.
The scheme includes 63km of stop bank and associated assets which is the length of the Waipaoa River from Te Karaka ou to the river mouth.
The project will improve the capacity of the existing scheme and:
- Address riverbank erosion. This will be through either providing rock protection or acquiring land in order to widen the existing river berm.
- Increase the width of the existing stop banks to 4 meters and increase the height by 0.6 or 0.9 meters in high risk areas.
- Maintain flood protection for a one-in-100-year flood event.
We're currently reviewing whether the project life cycle can be shortened to 10 years or less. Currently the project is forecast to occur over a 15-year period at a cost of $9.3 million.
The first stage of the project (priority 1) is set to commence construction in summer 2017/2018.
Currently, the annual construction length is 4km, with construction occurring only over the summer months.
