Useful for
- Use cases llm-inferred
- Screen a site against ACDP boundaries to decide whether Environment Agency consultation is needed (Devon and Cornwall) · Overlay ACDP coverage on constraints maps for drainage strategy scoping · Flag ACDP status in flood risk assessment desk studies for Devon and Cornwall sites
- Audience llm-inferred
- flood consultants · drainage engineers · planners · GIS analysts
Limitations
- Constraints llm-inferred
- Only Devon and Cornwall currently have ACDPs, so most of England will return no features · Dataset created 2016-06-10 and last revised 2025-07-25; boundary currency should be checked against the publisher · Distributed as a ZIP; the geodata format inside the archive is not stated in the docs · Coordinates are in EPSG:27700 (British National Grid), so reprojection may be needed for web mapping · Attribution required: © Environment Agency copyright and/or database right 2016.
