The region now consists of all the traditional areas noted above as well as the newly emerging suburbs and exurbs to the northwest, north, east and southeast of the city.

This allowed many new homes to be built on large blocks of land with no future urban provisions taken into consideration and in areas that were otherwise used for agriculture.
