Site constraints 7

Flood zone 3, rivers and sea
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.
The Environment Agency flood map for planning. Homes in zone 3 must also pass the sequential test. Surface water flooding is a separate map.
Flood map ↗
National infrastructure project: Thames Tideway Tunnel
The site is inside the project boundary. Waste water treatment, decided. The project page says whether consent was granted.
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.
Planning Inspectorate project page ↗
Air quality management area: Ealing AQMA
The council has declared the area as failing an air quality objective.
Schemes that add traffic, parking or combustion plant are assessed against the area's action plan and may need an air quality assessment.
Council record ↗
Conservation area 8 m away: Bedford Park
The edge of the area; work outside it can still affect its setting.
The council must give weight to preserving or enhancing the area's character and appearance. Not every council has published its boundaries as open data.
