Site constraints 7

Flood zone 2, rivers and sea

Medium chance: between a 1 in 100 and 1 in 1,000 annual chance from rivers, or 1 in 200 to 1 in 1,000 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 ↗

Article 4 direction

Article 4 Small Houses in Multiple Occupation (HMO) Area 1. Named permitted development rights are withdrawn here.

An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.

Air quality management area: Barnet 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.
