I'm not a planner and I really need help. In planning a new urban centre which will have retail, offices, accommodation and other facilities, does anyone know of an objective way of determining the amount of different amenities that a community may need?
For example, for a new community of, say, 20,000 people, how many doctors, dentists, clinics, schools, plumbers, builders, fire stations, church, library etc. should there be? Is there an objective or widely used ways of determining the number of these, say on a per capita basis?
If anyone know, please point me to the right direction, would be much appreciated.
