AvON asks council to create wetlands in residential red zone

Creating and restoring wetlands within the Avon River red zone will greatly improve the quality of the Avon River, says the Avon-Otakaro Network (AvON).

In its submission on the Christchurch City Council’s three-year plan, the organisation campaigning for a reserve and river park on the red zone land says there is little in the current plan to mitigate the harm contaminated stormwater does to the Avon River.

“One present ‘function’ of the Avon River is to transport contaminant-laden stormwater from the urban environment to the sea,” the submission says. “This activity has proven to have high levels of negative effects on nature’s services, i.e. water quality, biodiversity, flow regimes, flood control, community wellbeing, research and education. 

“The construction of wetlands in the residential red zone of the Avon/Otakaro River catchment will greatly assist in the improvement of water quality and flow regimes of the Avon River, enhance biodiversity and provide sites for research and places for people to gather.

“Avon-Ōtakaro Network requests the construction of wetlands within the residential red zone of the Avon/Otakaro River catchment – the wetlands to act as filters, intercepting stormwater before it enters the Avon River.”

The submission also calls for sewage overflow ponds to be introduced to prevent sewage entering the river, for cycle and walking paths within the red zone land, and for an interim management group to be created to work on a plan for the land.
