The Charlotte-Mecklenburg Storm Water fee pays for local efforts to reduce flood risks and reduce water pollution.   Storm water is rain water that does not soak into the ground. It flows into our storm drainage system without being treated or cleaned.   Managing storm water runoff is crucial to Charlotte-Mecklenburg’s quality of life. That includes maintaining and improving our storm water drainage system to reduce flood risks and working to reduce pollution levels in our creeks and lakes.   The cost of Charlotte-Mecklenburg’s storm water program is funded completely by a fee, not tax dollars. The fee is based on: 1)      how much each property contributes to storm water runoff and 2)      the cost of providing storm water services in Charlotte-Mecklenburg.
