As a general guide, post offices should be provided so that large groups of population in urban areas should have access to facilities within 0.8km from where they reside or work. For rural areas a distance of 3.2km should be assumed. Other factors to be considered include population in proposed catchment areas which would normally not be less than 30 000 persons; the nature of the terrain over which customers must travel; physical features such as busy main roads and railway lines etc.; the existence of any special social or postal need, and where the location is being considered as a focal point at which most of the day-to-day needs of the community will be provided.
The planning standards and guidelines should be applied with a degree of flexibility, having regard to land use demands, local conditions, development constraints, resource availability and financial viability.
