The strategic noise maps (CBS) are derived from the European Directive 2002/49/EC on the assessment and management of environmental noise. They are intended to inform the public about the levels of exposure to noise through graphic representations.
In accordance with article R572-5 of the Environmental Code, the CBS include maps, areas where the noise level exceeds 68 dB(A) in Lden (level day evening night, day-evening-night noise indicator, 6am-18h, 18h-22h and 22h-6h). They are called ‘C-type card’.
Limit values in dB(A) are defined by article L572-6 of the Environmental Code.
The CBS of the major road infrastructure, whose annual traffic is more than 3 million vehicles, with a deadline for the Val-d’Oise, were approved by prefectural decree of 5 December 2018.
They must be reassessed every 5 years.
