2017 Map of O'Fallon

About this map

O'Fallon and the surrounding Saint Charles County landscape show the results of rapid suburban integration in this 2017 survey. The map records a dense network of residential developments and commercial corridors such as E Terra Ln and Mexico Rd, which have largely bridged the gap between established centers like St. Peters, Lake St. Louis, and Cottleville. Despite this growth, older community anchors remain visible, particularly through religious and genealogical sites including the Sisters of the Most Precious Blood Cem, Assumption Cem, and Sage Chapel Cem.
