The given map diagrams illustrate the changes which took place in the city of Langley between 1910 and 1950.
Overall, the main trend is that industrial zones were removed and replaced with commercial buildings and residential areas. The city became more developed, with many old buildings being replaced by modern facilities.
In 1910, the town contained several industrial zones with buildings for railway workers. In the west of the map, there was Jordan Street surrounded by numerous townhouses and trees. At the center, Sherman Street featured residential buildings and a café next to them. Moreover, opposite the café, a laundry was situated with a store behind it. Both the north and south sides of Sherman Street contained large areas of wasteland. While the northern wasteland included a factory, several cottages for railway workers were located in the southeast corner of the map.
Over the next forty years, the town underwent significant transformations. Townhouses were converted into modern flats. The factory site was replaced by three buildings known as the Sherman Mansions. Furthermore, there was a complete transformation into a park called Sherman Park with green grass, a lake in the middle, trees, and a play area for children. Cottages for railway workers were knocked down to build three stores next to the park. As a result, the laundry and the café, which were originally located, were relocated to the northeast corner of the map.
