Where does this data come from?

This LocalRisk report for M9 0GG 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 Manchester and is updated as new official datasets are published.

These are postcode-level indicators - conditions vary between individual properties.
