Site constraints 4

CAA Height > 90m
National infrastructure project 784 m away: M4 Junctions 3 to 12 Smart Motorway
The site is 784 m from the project boundary. Highway, 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.
