The development of an area must not affect residential areas. The principle of concentration is to be applied in this context as well, leading to few but busy development roads.

Areas with truck deliveries as well as the transportation and handling of goods must be thoroughly shielded in a noise-sensitive neighbourhood. What must also be taken into account is noise from parking areas and parking garages (e.g. through the banging of doors).

Spare designations of access and departure roads of commercial sites can help to localize development noise and keep it away from adjacent residential uses wherever possible. Sufficient parking and shunting possibilities should be available for the truck traffic which is to be expected in these cases. Although separate access and departure roads contradict the principle of concentration, they may help to prevent the particularly disturbing shunting and turning noises from heavy goods vehicles, which also supply to small grocery stores situated in residential areas.
