SITE AND SITUATION
- Site is the specific place where the city is established. At the beginning it played a very important role. Cities were near rivers or on a hill top for a better defense.
- Situation is the relation of the city with the surrounding areas for example ports, road intersections, in the center of a country.
A plan is the graphic representation of the distribution of the built-up areas (houses and other buildings) and the open spaces such as streets, parks or squares.
There are three types of plan depending on the shape and arrangement of the roads:
- ORTHOGONAL PLAN is also called grid plan or checkerboard. This plan has straight, wide streets that cross at right angles.
- RADIOCENTRIC PLAN starts at a central point and from there streets radiate crossed by others that form concentric circles.
- IRREGULAR PLAN does not have a defined geometric shape. It is formed by short and narrow streets and alleys of irregular layout.
