Climate Risk Engines collates data on rising sea levels, shifting terrestrial heights, historical tides and extreme sea events to assess the risk to a property. The frequency and extremity of previous sea events are taken into account, as are adjustments for land movements.
The vulnerability of a property flooding from coastal inundation is determined by a range of characteristics; proximity to the coast, elevation, foundations of the building and materials used are key determinants. Properties that have a low elevation and are close to the coast with no physical barriers or protection are more at risk of extreme weather events.
The way a building’s foundations and materials respond to water also helps determine its vulnerability (materials like concrete slab, waterproof membranes in the walls and glass blocks are more resilient than wood and traditional brickwork.)
