Norwich is set to join New York, Shanghai and Cardiff as a "spongy" city. 

City Hall will be combatting the growing threat of flash flooding by transforming the city into a 'sponge'.

Spongy cities are designed to absorb rainwater by using green spaces to help lower the amount of extra rainwater hitting sewers.

This closely follows the recent flash flooding in Valencia in Spain in which 224 people died and there are hopes that this initiative could make Norwich more resilient to additional flooding caused by climate change.

"Aviva reports that 100,000 homes have been built on floodplains in the last decade, with many now becoming uninsurable.

Councillor Gary Champion highlights that the council, businesses and city locals need to work together for this to work.

He added: "Spongy city principles have been shown to work in various Chinese and Latin American cities with success and have restored the city's capacity to absorb, infiltrate, store, purify, drain and manage rainwater.

The move to transform Norwich into a Spongy City also helps stop the growing trend of urban areas becoming increasingly grey and concrete, which makes areas more vulnerable to flooding.

The council's new initiative seeks to reverse this trend and create a more sustainable balance between development and green infrastructure.
