The suburb of Naperville, Illinois is marked by several characteristics: rapid growth from the 1960s onward, particularly between 1980 and 2000, and lots of land annexation; wealthier suburban residents and numerous white-collar jobs; and a lively downtown with national retailers, local stores, plenty of restaurants, and a nice Riverwalk. Will any Chicago area suburb trace a similar path in the future?

Here is why I would guess no:

1. Limited population growth in the Chicago suburbs. The whole region is not growing much. Population growth in the suburbs could still be uneven; some places are perceived as more desirable or are more affordable and they could grow faster will others stagnate or even shrink. But explosive population growth in the Chicago area looks like it is done.
2. At multiple points in Naperville’s history, leaders and residents discussed possible development and regulatory options. They tended to choose growth and in particular forms. These sets of decisions helped give rise to the particular traits of Naperville today. Even if another suburb tried to pursue the same path, not all the pieces might fall together in the same way.
3. When Naperville grew from 1960 onwards, it was closer to the edge of the metropolitan region. Land was cheap and available. The city could annex land without running into other communities. That growth has since moved out further beyond Naperville’s ring, out to places like Aurora and Plainfield and Oswego. Any future Naperville will be 10-30 miles out from Naperville.
4. Naperville itself – and other older suburbs – will likely change in the future. If Naperville wants to continue to grow in population, it will need to grow denser and taller. Infill development on small parcels could add lots of townhouses, condos, and/or apartments. Redevelopment in desirable areas and around mass transit options could lead to taller or denser buildings. This all could happen in numerous Chicago suburbs but this will move them away from homes dominated by single-family homes and lifestyles.
