Article 4 direction
Other Article 4 Direction Area. Named permitted development rights are withdrawn here.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: Waltham Forest 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.
Opportunity area
Where the London Plan expects significant growth.
Boundaries are indicative and the borough holds the detailed plan.
Also on the record
Radon affected area, class 2; Inside the Waltham Forest built-up area; Public transport access: PTAL 2 (poor), TfL 2023, for the 100 m square.
Not affected
