Available to LG Inform Plus subscribers, it provides information on what current legislation gives English and Welsh councils the power to do and what it requires them to do in law. Advanced searching and filtering options make it easy to find specific powers and duties based on legislation, business function and keyword, and results are easily exported in commonly used formats.

Percentage of the population exposed to road, rail and air transport noise of 55 dB(A) or more during the night-time (12030) Metric type
- Help text
- Percentage of the population exposed to road, rail and air transport noise of 55 dB(A) or more during the night-time. Noise exposure is determined by strategic noise mapping (produced in connection with the Environmental Noise Directive (END)) using national calculation methods and input data supplied from the relevant authorities. The results overlaid on a residential population dataset to determine number of people exposed per authority. The data have been derived from the results of the separate mapping of the three sources. The number of people exposed to more than 55 dB(A), Lnight (LAeq,8h) from each source has been summed to produce the overall result. This method does mean that an individual exposed to more than this value from more than one source will be included more than once in the overall total.
