High chance: a 1 in 100 or greater annual chance from rivers, or 1 in 200 from the sea. Any development here needs a flood risk assessment. Defences are not counted.

Council record ↗
National infrastructure project about 295 m away: Thames Tideway Tunnel
The site is about 295 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: Silvertown Tunnel (decided, about 1722 m).
Nationally significant infrastructure projects (power stations, electricity lines, pipelines, major roads and railways, harbours, airports and reservoirs) are consented by a Secretary of State under the Planning Act 2008, after an examination by the Planning Inspectorate, rather than by the council. The boundary is the one the Inspectorate consults on and can change as the scheme does. Projects are shown within 2 km of the site.
