What this means for your coverage
St. Charles sits where the Missouri and Mississippi rivers meet, and with about 43% of unincorporated county land in a floodplain, homeowners and business owners here often need a separate NFIP or private flood policy on top of a standard home policy, which excludes flood. The region's large-hail events (baseball-to-softball-size hail in May 2016) and tornado history make wind/hail roof coverage and comprehensive auto coverage especially important. A growing population with a renter share around one-third and a heavy manufacturing/logistics employer base also drives demand for renters, landlord, commercial property, and workers-comp coverage.
