Case study figures and drawings

The drawings, plans and maps on our case study pages and several service pages are Flood Risk Environmental's own project deliverables, reproduced at web resolution. Maps are built from open data: Environment Agency flood mapping and LiDAR (Open Government Licence v3.0), BGS geology (© BGS/UKRI), on a basemap © MapTiler © OpenStreetMap contributors (ODbL). Drawings are shown over topographical survey bases commissioned by our clients. Site photographs on the Pulborough case study and the soakaway testing page are from the June 2026 BRE 365 test pack by Simon Harvey Designs Ltd, reproduced with permission.
