Flood Map for Planning: Surface Water Extents Under Climate Change Scenarios

Environment Agency's Flood Map for Planning Service includes Surface Water Spatial Planning Extents. These datasets show land at risk from surface water flooding for three annual exceedance probabilities, incorporating climate change projections for the 2070s epoch. The data is based on UKCP18 climate projections using the RCP 8.5 scenario.

Use Cases

• Assess long-term land suitability for development based on surface water flood risk extents.
• Model future flood risk scenarios for infrastructure planning based on climate change allowances.
• Compare flood risk across different probability thresholds (0.1%, 1%, 3.3% AEP) for strategic planning.

Strengths

• Covers three specific flood probability scenarios: 0.1%, 1%, and 3.3% Annual Exceedance Probability.
• Incorporates climate change projections for the 2070s epoch (2061-2125) based on UKCP18 RCP 8.5.
• Produced by the authoritative Environment Agency for the UK.

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.
• Data is designed for indicative area-level risk, not for assessing risk to individual properties.
