On 28th February the Environment Agency held a Flood Awareness Event sharing how they are managing flood risk and what's next for the Flood Alleviation Scheme.
"Significant flooding occurred in Leatherhead and Fetcham in 1947, 1960, 1968, 1974, 1990, 2000, 2008 and most recently during the winter of 2013/2014.
All of these floods had a major impact - damage to property, disruption to business, distress and upheaval to people's lives, and the continued threat of another flood. We have therefore been working to identify and implement ways to reduce flood risk in the catchment.
In response to these devastating floods, the Environment Agency has worked to identify and implement ways to reduce flood risk in the catchment.
The current project is looking at the risk to Leatherhead and Fetcham from river and surface water flooding.
20 options for reducing both river and surface water flood risk were assessed. These options were identified in partnership with Surrey County Council, Mole Valley District Council and Thames Water. They have previously been shared with the Leatherhead and Fetcham Flood Action Group. We assessed these options technically, financially and environmentally to see which ones had the potential for further consideration.
The preferred way forward to reduce the impacts of both river and surface water flooding in this area is a property level flood resilience scheme. Property level flood resilience offers more benefits to properties than the other options considered and had the highest scoring cost benefit ratio.
A variety of measures can be used to manage flood risk. Resistance measures help stop flood water getting into a property. These include permanent flood doors, removable flood barriers and airbrick covers. Resilience measures help minimise the damage flood water can cause, these include tiled floors and raised plug sockets.
170 residential properties in Leatherhead and Fetcham have been identified as eligible. The aim of these measures is to minimise the impacts of flooding and significantly reduce the time and cost of restoring the property after a flood event.
As property resilience projects are simpler than large civil engineering works, we will be able to start putting these measures in place quickly. Consequently residents will reap the benefits of the scheme much more quickly.
The next steps are:
