Neighborhood Watch is composed of citizens interested in decreasing the amount of crimes, such as burglary and vandalism, that occur in their neighborhoods. As part of the program, unincorporated residents of St. Charles County are trained to protect their property and themselves by securing their home from unlawful entry.

The Neighborhood Watch Program stresses identifying your personal property through marking, photographing, and preparing property inventories.

Citizens are trained to report suspicious activities to the Sheriff's Department immediately and trained to report the proper sort of information that is needed by the Sheriff's Department to be effective in responding to suspicious activity calls.
