Town planning has been going on for centuries and no matter how clever we think we are in modern times we are but living off the knowledge of those that have gone before. Most major cities have been planned at their inception and have grown over time into large populated areas but what they all started with was a centre and the rest of the development was worked out from there.

No matter where you go the thing you will most find in any town or city is that the majority of streets are laid out in a grid pattern, with the centre being where all commerce is conducted, it makes sense to have the middle of a town where everyone goes to trade, this is a throwback to times when it was prudent to have your supplies well-guarded against intruders and invaders.
The trading is in the middle, generally official buildings are not too far away from this area and then comes the mix of industrial and housing areas, during the industrial revolution there was a hodgepodge of the two mixed up together and this led to a more structured framework for where industry could set up and which areas were to be strictly residential. England had immense problems with pollution and the populace being adversely affected during this time and it was a horrible time to be a pauper and if you were a child, well you might as well have just thrown yourself under some carriage wheels and saved yourself some time.
America and its rapid growth, saw little town’s spring up everywhere and they were traditionally laid out in the same fashion, a long main street with intersecting roads, businesses along each side and then in the streets behind were where the residents lived. Many business owners lived above their shops or out the back of them and there were the farmers and homesteaders who came to town for supplies and recreation, none of these towns were specifically planned, they grew organically over time and it was only when the town became large enough to elect town officials that the planning became more formalized.

This is the way of many small towns and the initial beginning of cities, they start out with a simple plan of two intersecting streets and then as the city grows the plans have to become more complicated. Taking into account city growth, the hygiene of residents and where the sewerage is going to be going, organizing residential and industrial areas and the laying out of roads. This is where rezoning has come from, where people have had to move because the area they have lived in is now an industrial area and they are surrounded by factories and manufacturing. You can still find a few hold outs who have remained in the family home but it is only a matter of time before these are gone as well and the area is completely industrialized.
