Runoff from unpaved surfaces due to 25-year, 24-hour storm event and average winter precipitation over the storage period (cubic feet) This value is going to vary depending upon your location in the state - use Table d as a guide. These conservative values are based on a 120 day storage period (December , through March). A longer storage period (980 days) and higher than average winter precipitation values and runoff coefficients should be used in areas with high rainfall and runoff such as the North Coast. #29 x Table 4 value = 11(4no period = + #32 33.
