This LocalRisk report for TR17 0AG draws on four official UK open data sources: Environment Agency NaFRA2 flood modelling, Met Office UKCP18 climate projections, Defra UK-AIR PM2.5 monitoring, and British Geological Survey GeoClimate subsidence mapping. Risk ratings are a screening tool, complementing - not replacing - the searches and surveys ordered as part of a property transaction. Data covers Cornwall and is updated as new official datasets are published.
Cornwall has an exposed coastal and rural setting with upland moors and river valleys and experiences cool, wet winters and mild summers, shaped by Atlantic influences and varied topography.
