(25) "Ten-Year Storm" means a rainfall of an intensity that, based on historical data, is predicted, by a method acceptable to the approving authority, to be equaled or exceeded, on the average, once in 10 years, and of a duration that will produce the maximum peak rate of runoff from the watershed of interest under average antecedent wetness conditions.

(26) "Twenty-five Year Storm" or "Q25" means a rainfall of an intensity that, based on historical data, is predicted, by a method acceptable to the approving authority, to be equaled or exceeded, on the average, once in 25 years, and of a duration that will produce the maximum peak rate of runoff from the watershed of interest under average antecedent wetness conditions.
