A 100-year storm events analysis was conducted using the IHethodology described in the. County of San Diego, Hydrology Manual for developed site. The rational method was used to determine the flow contributions from each basin. (See Exhibit “A", and. Appendix A). It was determined. concentration (Tc) of the contributing drainage area. A is the drainage area in acres tributary to the design point. Runoff Coefficient, C. For existing conditions, the San Diego County Hydrology Manual was initially used. We chose the Permanent Open Space runoff coefficient within soil Type “D" (see section 2.2 for soil type. c) or, tº may be calculated using the following flow formula for developed areas with overland flow: t="1".801.1-C) ND (in minutes). WS. D = Length of watercourse (feet). S = Slope (percent). C = Runoff coefficient d) For limitations in using these formulas, refer to the San Diego. County Hydrology Manual.
