During the housing bubble of the mid-2000s,  a few new subdivisions were planned to be built north of town.  When the housing market crashed, the city had already incorporated a large portion of DeKalb county north of town ranging from the Sandwich Township border to Governor Beverage Highway, remaining south of Pratt Road.  Since then, no talk has indicated that the subdivisions will be built.

The nearby [[Lake Holiday, Illinois|Lake Holiday]] area includes a man-made lake created by the damming of Somonauk Creek.<ref name="lh">{{Cite web|url= http://www.lakeholiday.us/|title= Lake Holiday|access-date=February 15, 2013|work=Official website|publisher= Lake Holiday Property Owners Association|date=February 14, 2013}}</ref> An old gravel pit was also flooded and is part of the lake.
