ESI launches detailed groundwater flood risk map

Environmental consultancy ESI has launched a new groundwater flood risk map, which it claims offers greater detail and accuracy.

The new map is based on a 5m dataset that allows groundwater flood risk for individual properties to be assessed.

According to ESI, this new accuracy is a major step forward in groundwater flood assessment and will address an issue that costs the UK economy £210M per year.

The new map builds on the existing product, which was launched in 2013 and based on a 50m resolution map.

“Groundwater flooding is the hidden face of flood risk, and with climate change continuing to impact weather patterns, the result is a greater need for more comprehensive information about ground conditions, groundwater and flood risk,” said ESI CEO Stuart Pearce.

“Our new Groundwater Flood Risk Map reflects ESI’s ongoing investment in delivering the best groundwater data available in the market with unequalled accuracy. With more location specific data, users will have far greater confidence in knowing individual conditions than ever before. This means a far more informed choice, with major benefits for the property, infrastructure and insurance industries.  

“Enhancing resilience to extreme weather will be an important aspect of future economic competitiveness, and mapping of groundwater flood risk areas provides important preparation support for emergency response, flood mitigation and land-use planning, as well as the assessment of climate change impact.”
