The maps are published to mark National Noise Action Day, which was 7 June. CPRE hopes that public concern over visual and noise intrusion will pompt the Government to action. “We’re campaigning to gain official recognition for tranquillity in the Government’s rural white paper,” a CPRE spokesperson told edie.
The maps were originally produced a couple of years ago by CPRE and the Countryside Commission. To create them, tranquil areas were defined as areas:
- 4km from large power stations
- 3km from the country’s busiest roads such as the M1 and M6
- 3km from large towns (the size of Leicester or larger)
- 3km from major industrial areas
- 2km from other motorways, major trunk roads (such as the M4 and A1)
- 2km from smaller towns
- 1km from “medium disturbance roads” (defined as difficult to cross in peak areas)
- 1km from some mainline railways
- beyond military and civil airfields and airport noise
- beyond extensive opencast mining
Tranquil areas are a minimum of 1km in radius and analysis shows that such areas reduced in size by 73% in 30 years. The total “area of tranquillity in England” dropped by 21% in the same period, from 91,880km² to 73,012 km².
CPRE’s maps are available in A4, A3 and A2 sizes.
