LAIRD, Acting Director County of San Bernardino Transportation/Flood Control File: l(FC)-53 SUBJECT SAN BERNARDINO COUNTY DETENTION BASIN DESIGN CRITERIA As requested the subject criteria the determination of pre -development to the existing criteria the County calculated peak flow rate will equal at a given concentration point if available. Therefore, the County ca a detention basin outflow will no properties (not considering erosion) was reviewed with respect to peak flow rates. According can be 85% confident that the or exceed the peak flow rate adequate streamflow data was n only be about 15% confident t adversely affect downstream The County should be at least 50% confident a detention basin outflow will not adversely impact properties downstream of the basin. Based on the calibration study of the county's hydrology method the input parameters (procedures) described in the Manual should be modified as follows: a) 10 year peak flow rates should be calculated using 5 -year rainfall, b) 25 -year peak flow rates should be calculated using 10 -year rainfall, and C) 100 -year peak flow rates should be calculated using 25 -year rainfall and AMC II. If these design parameters are used for determining the pre - development peak flow rates, the basin outflow metered to 90% of these calculated pre -development peak flow rates and the post - development peak flow rates to the basin calculated in accordance with County Hydrology Manual, the County will be over 50% confident the resulting basin design will not adversely affect adjacent or downstream properties (not considering erosion). The desired confidence level for detention basin outflow is a policy decision. Once the desired confidence level is determined the required input rainfall amounts can be developed to calculate the peak flow rate at the corresponding confidence level. I have discussed this policy issue with John Pederson of the U.S. Army Corps of Engineers, Ron Moore of the Soil Conservation Service and Al Nessinger of Orange County. Al Nessinger pointed out by using basin inflow hydrographs based on a 85% confidence level 12.1367000 Rev. 9/85 petention Basin Desirm Criteria for San BernarcLino County page 2 , W II. Basin Capacity and Outlet. gain A. When a basin (regional, local, temporary or joint use) is to be used to mitigate downstream impacts due to increased flows generated by a development, the basin capacity and outlet size shall be such that the post -development peak flow rate generated by the site shall be less than or equal to 90% of the pre --development peak flow rate from the site for all frequency storms up to and including 100 -year (i.e.) the peak 2 year post -development flow rate is equal to or less than/ 90% of the peak 2 year pre -development flaw rate from the site and etc. for all frequency storm events through 100 year). 1. Only 2, 10, 25 and 100 -year storms need to be analyzed. 2. Post -development peak flow rates shall be calculated in accordance with the "San Bernardino County Hydrology Manual". 3. Pre -development peak flow rates shall be calculated in accordance with the San Besnaitlino County Hydrology Manual" with the following exceptions. a) 10 -year peak flaw rates shall be calculated using 5 -year rainfall. b) 25 -year peak flaw rates shall be calculated using 10 -year rainfall. c) 100 -year peak flow rates shall be calculated using 25 -year rainfall and AMC.` -II. 4. Additional studies shall be submitted where there exists more than one basin in the drainage area under review. The studies shall address the timing of the peak flow rates from the basins to ensure downstream flow rates are not increased. Nemo to Charles Laird September 4, 19 Page 2 and by creating adequate storage to reduce the peak flow rate from the basin to 90% of pre -development condition based on a 500 confidence level, the resulting confidence level that downstream conditions have not changed will be greater than 50%. Also, the rainfall pattern used in the hydrograph method was chosen to be the most severe test on basin design. When these facts are combined with criteria of using multi -day storms, the resulting basin design should be adequate to ensure downstream properties will not be subject to increased peak flow rates. Ron Moore felt the revised criteria better fit the actual pre -development conditions in the field. John Pederson and Al Nessigner both felt the criteria should be tested against actual occurrences in gaged watershed. Attached is page 2 of the design criteria with the proposed changes shown in bold type. Should you have any questions, please call. RWC:mjs Attachment cc: Ken Miller IF NO I'AI NO I.
