Flood Map: Flood Zone 2 Areas in Wales

Wales is the geographic scope of this dataset, which shows areas with a 1 in 1000 annual chance of flooding from rivers or the sea. It was produced by the Government Digital Service and includes flood defences and the areas they benefit. The dataset was discontinued and superseded by a new Flood Map for Planning in late Summer 2021.

Use Cases

• Assess property and infrastructure flood risk based on the defined flood zones.
• Plan land use and development restrictions based on areas with a 1 in 1000 annual flood chance.
• Model the effectiveness of flood defences based on the areas they are designed to protect.
• Raise public awareness of flood likelihood for residents in the mapped zones.

Strengths

• Provides a defined geographic scope covering Wales.
• Includes a specific flood probability metric (1 in 1000 annual chance).
• Contains multiple information layers, including flood defences.

Limitations

• The dataset is discontinued; its relevance and accuracy may be outdated.
• Row count, file formats, and column-level documentation are unknown.
• Last update date is unknown; freshness unverified.
