The plans illustrate the center of a small city (Islip) that has gone through some changes.
Overall, it is clear that this part of Islip has gone through radical alterations more significantly in the center of this region, as it was developed and converted into a massive commercial and residential area.
First, as can be seen from these maps, on the western side of this area there used to be the main road which is expanded to a dual carriageway and created a circle design to facilitate transportation to various parts of this town. Also, in the north of this region, there was countryside which destructed for the expansion of the road.
Besides, in the middle part of these plans, there were several shops by the main road among them, as all of them were removed with exception of the shops, which were located on the south of the main road which remained intact, while the main road converted into pedestrians only. Moreover, all shops were removed, yet a bus station, a shopping center, a car park, and new housing were erected. In the bottom right-hand corner there used to be a large park which diminished in size, due to expansion of the road. In the south of this region, there were some scattered housing which they separate into two parts two housings, and with new housing being constructed. Finally, there used to be a house in the bottom left-hand corner which expanded in size.
