There are 4,552 homes in Aylesbury at risk of flooding according to Friends of the Earth which wants to see action taken on climate change.
According to an analysis of Environment Agency data released today by Friends of the Earth, there are 13,429 homes at flood risk across Bucks, of which around a third are in the Aylesbury area.
The figure includes 534 homes in Aylesbury which have been judged by the Environment Agency to be at significant risk – more than a one in 75 chance during any given year.
Friends of the Earth says its figures show there is a much larger number of properties in the UK that could face flooding in future.
This it says is a concern as climate change is set to make flooding more widespread.
Friends of the Earth south east regional campaigner Brenda Pollack, said: “Flooding is devastating for anyone that is affected by it and as a country we must do much more to prepare for the impacts of climate change.
“Without proper investment in flood defences, hundreds of thousands more homes could be put at risk of flooding.
“Prevention is better than cure, so it’s also vital that the Government redouble efforts to stop climate change becoming worse.”
“We are asking Buckinghamshire MPs to support the call for flood defences in line with the risks posed by climate change, and for more investment to make homes energy efficient, switch to renewable energy and get off climate-changing and polluting fossil fuels.”
