Site constraints 10

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 ↗
Public footpath 18 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 ↗
Habitat network: Priority Rivers
Where habitat is joined up enough to work as a network. Context, not a constraint on its own.
Also on the record
National infrastructure project 18 m away: Expansion of Heathrow Airport (Third Runway), at pre-application; Flood defence 24 m away (natural high ground, designed for a 1 in 200 year flood); Inside the Richmond upon Thames built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square; Priority habitat 18 m away: Deciduous woodland; Metropolitan Open Land 18 m away.
