In addition to containing more elaborate homes on larger lots, the western section of Highland-Douglass featured a street pattern which represented a departure from the grid style subdivisions that were popular at this time. In addition to showing a greater respect for the natural topography of the land, there was a growing trend around this time towards subdivision design which included large lots, encouraged natural topography, and preferred street patterns which discouraged through traffic in residential neighborhoods. This proved to be more profitable in the long run as well as more appealing to affluent home buyers.
The area which made up the eastern portion of the Douglass Park sub- division developed more slowly than the western portion. Most of this area was subdivided between 1938 and 1952. The prevalence of more contemporary style homes and ranch houses along with the occasional historical revival home along Carolina Avenue, Moyle Hill Road, Mill- vale Road, and Valletta Lane are an indication of the numerous subdivisions and re-subdivisions that took place.
