Site constraints 13

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 ↗

Castelnau conservation area

Demolition needs planning permission and permitted development is restricted.

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.

Council document ↗

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 ↗

Public footpath 16 m away

Matters where it crosses or adjoins the site: obstructing a path without a diversion order is an offence, and work cannot start until the order is confirmed.

Compiled from highway authority data, not the legal definitive map. A few authorities have not published, so no path shown is not proof there is none.

Air quality management area: Richmond 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 ↗

Thames Path 16 m away

Matters where it crosses or adjoins the site; the route and its margin are protected.

Habitat network: Network Enhancement Zone 2

Where habitat is joined up enough to work as a network. Context, not a constraint on its own.

Also on the record

1 listed building within 150 m; SSSI 303 m away: Barn Elms Wetland Centre SSSI; Flood defence 11 m away (wall, designed for a 1 in 1000 year flood); Inside the Richmond upon Thames built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square; Metropolitan Open Land 12 m away.
