Rainfall Intensity Values

The Rainfall Intensity Values charts were developed by the SCDOT that are based on the Technical Paper 40 maps to aid in calculating intensity values for the 5, 10, 25, 50, and 100 year storms. Values are listed for 28 cities in South Carolina. Use the values that most represent the rainfall pattern at your specific site.
