What is Groundwater Flooding?
Groundwater flooding is responsible for about a quarter of all property and infrastructure risk and can cause a multitude of damages. It is particularly prevalent where chalk, sandstone, localised sands or river gravel in the bottom of valleys are present.
There are multiple ways that groundwater can have an effect on a property or development, and it is important for developers, planners, architects and anyone involved in a project to understand the risks.
How can GeoSmart help?
If your Site has a high risk of groundwater flooding, you may need more information, whether you’re purchasing a property, or developing a Site and need planning permission.
GeoSmart can provide Groundwater flood risk data, as well as more detailed Flood Risk Assessments with a focus on Groundwater.
GeoSmart’s Groundwater Flood Risk Assessments (GWFRA) are the first ever reports to demonstrate the risk to a site from groundwater flooding. It provides the most accurate method of screening and assessment at postcode level available.
Our reports are based on GeoSmart’s 5m Groundwater Flood Risk Map (GW5). The assessment will screen for groundwater flood risk and then our highly experienced hydrologists will investigate the physical and environmental setting, including local geology, groundwater levels and topography. As a further cost option, LIDAR data can be used for more complex sites.
Based on a simple traffic light system, the flood risk report is quick and easy to understand. Detailed guidance and clear recommendations on next steps are provided.

- Quick turnaround options available
- Low cost / fixed price
Based on:
- Site location plan and proposed development plans are available
- Site walkover survey is not required
- No intrusive site investigation is required
- Advance payment is made
- For more complex sites where highly accurate height data (usually LIDAR data) is deemed necessary to inform groundwater flood risk, it is assumed that data will either be supplied to GeoSmart, or GeoSmart is permitted to purchase the data on your behalf (a fee applies). If highly accurate height data is recommended but not included, the report findings and conclusions cannot be guaranteed. This is because the assessment of groundwater flood risk may be inconclusive without this level of topographical detail
If your site doesn’t fit these assumptions or you require a site walkover survey, we can still assist but please do get in touch as one of our other packages may suit you better.
