Site constraints 12

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 ↗
Article 4 direction
Old Kent Road North District Town Centre. Named permitted development rights are withdrawn here.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.
Archaeological priority area: North Southwark and Roman Roads
An assessment or field evaluation may be asked for before ground works.
The council or Historic England considers archaeology likely here. A desk-based assessment, and sometimes trial trenching, can be asked for with the application.
Air quality management area: Southwark 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 ↗
National infrastructure project 888 m away: Thames Tideway Tunnel
The site is 888 m from the project boundary. Waste water treatment, decided. The project page says whether consent was granted. Also within 2 km: London Strategic Heat Main Project (at pre-application, 616 m).
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 ↗
Conservation area 15 m away: Thomas A'Becket and High Street
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.
Council document ↗
Opportunity area
Where the London Plan expects significant growth.
Boundaries are indicative and the borough holds the detailed plan.
Also on the record
Wider setting of protected view 23A.1 Centre of Bridge over the Serpentine to the Palace of Westminster; Radon affected area, class 2; 1 listed building within 150 m; Inside the Southwark built-up area; Public transport access: PTAL 5 (very good), TfL 2023, for the 100 m square.
Not affected
Not green belt · No scheduled monument at the site
