Reduce London’s flood risk by ‘reviving rivers’ says Environment Committee


The London Assembly Environment Committee has called for more impetus on sustainable drainage and river restoration to reduce flood risk.

The committee says focusing on these initiatives will create space for flood waters to be held higher in the river catchment and soak back into the ground.

It adds this will allow low-lying areas to flood safely at times of high water flow and is likely to “protect homes, roads and businesses”.

The message is part of the Committee’s summary of the flood risks facing the Capital.

According to the summary, 24,000 properties in London are at significant risk of river flooding. The Environment Agency estimates plans currently under development could protect 10,000 of these.

However, the committee also warns that the risks of flooding may be increasing. The effects of climate change in southern England could mean drier summers and wetter winters, it states.

More heavy rain in the Thames region would increase surface water risk and may lead to more river flooding in London.

“London needs to bring back its rivers to protect itself from inevitable flooding in the future,” said chair of the Environment Committee, Murad Qureshi. “The more we can restore natural banks to London’s rivers, the less likely heavy rain will cause the degree of flooding we saw in the early part of this year,” he added.

“Heavy or prolonged rain locally or upstream can cause rivers to flood. Tens of thousands of properties are at high or medium risk of river flooding. This is not just from the Thames but also from the many smaller rivers that flow into it,” he added.
