Risk of Flooding from Rivers and Sea: Property Area Assessments for England

England's Environment Agency provides an assessment of flood risk from rivers and the sea for areas linked to properties. The dataset includes Ordnance Survey references for linking to AddressBase and OS MasterMap. RoFRS outputs estimate flood risk to an area of land and are generally not suitable for property-level assessment.

Use Cases

• Assess regional flood exposure for land-use planning based on the RoFRS area risk assessment.
• Link flood risk areas to property databases for aggregate analysis using the provided Ordnance Survey references.
• Model potential flood impact zones for infrastructure projects based on the likelihood of flooding in an area.

Strengths

• Data is sourced from the authoritative Environment Agency and the Centre for Ecology and Hydrology.
• Includes Ordnance Survey references enabling linkage to detailed address and topography datasets.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The method does not provide information on floodwater depth or timing of property damage.
