St. Charles & Kane County specifics

St. Charles has a population of roughly 33,000 and its Kane County portion lies in Wayne Township and nearby areas, with the county seat at Geneva. The Fox River runs through the city and carries substantial FEMA Special Flood Hazard Areas, making accurate as-built elevations especially relevant for grading and floodplain compliance. City engineers use the as-built survey to confirm that a new subdivision or commercial build was constructed as designed before acceptance. Recorded plats and related documents for the Kane County portion are filed through the Kane County Recorder. The survey gives all parties a verified account of the finished work.
