Where : I = design rainfall intensity (in./hr.) 3-year frequency-a rainfall intensity having a 33 percent probability of occurrence in any given year. We are working to resolve the issue as quickly as possible. The runoff coefficient for a non-developed land is 0.30. The new tool was designed to maintain a similar interface and data structure to ensure that the revised coefficients can be inserted into existing design software (GeoPack-Drainage, WinStorm, and other drainage design tools that directly use the E, B, and D values). Meanwhile, continued use In most cases storm water runoff can be calculated using the Rational Method. volume, and floodplain storage.

The rainfall coefficients (E, B, and D) for the spreadsheet were created by interpreting the rainfall depth contours by duration and frequencies from research by the National Weather Service completed in the early 1960s and augmented in the 1970s. Highly porous or permeable soils that can rapidly infiltrate rainfall generally produce less runoff volume than soils with more restrictive infiltration. Upon clicking a state on the map above or selecting a state name from the drop-down menu, an interactive map of that state will be displayed.
