Parks and forests (parks, forests, nature reserves, recreation grounds) and all greenery (plus gardens, meadows, orchards, vineyards, allotments, cemeteries, scrub) are counted from the district’s area; overlapping areas only once. Traffic noise is taken at the loudest point within 20 m of the address, usually the street-facing façade, from the 2022 strategic noise map as Lden: the average over the whole day with evening and night weighted up, so it reads a few decibels higher than daytime noise alone.
