The Brownfield Ground Risk Calculator is an award winning spatial decision support tool for understanding ground conditions and is developed by the British Geological Survey (BGS). "The Brownfield Ground Risk Calculator is a digital planning tool presented in a geographical information system (GIS). The Calculator has been developed to understand and communicate the scale of risk and cost associated with brownfield ground conditions. The conditions considered are above and beyond those expected when normal development conditions prevail - these are often referred to as 'abnormals'. The ground conditions considered by the Calculator include:
- soil and groundwater contamination; and
- land stability and ground gases.
The Calculator is designed to inform decisions made early in the planning process by public bodies, developers and land owners. Decisions made early on in this process, can affect the economic viability of building new homes on brownfield land, this includes any land that has a record of having been previously developed, including waste disposal or mineral extraction activities."
