Storm Drainage Report, RAM Engineering 8/14/2015 Section E. WWHM2012 has had several updates since the 2015/03/18 version (used in the report).Please download the most current version (Clear Creek Solutions website) and use it for this project. Section 5.7.4.2 of the Edmonds Stormwater Code Supplementstates that the minimum orifice size for a detention system is 0.5 inches, an orifice smaller than this is proposed in the report.As stated in Section 3.2.4 of the 2005 Ecology Stormwater Management Manual for Western Washington, if the allowable discharge cannot be met even when the live storage depth is reduced to 3 feet using a 0.5 inch orifice, that’s all that is expected.The allowable discharge rates can be rounded to 0.009, 0.018, and 0.042 cfs, if that helps. Plans Once a notched weir has been modeled for compliance, place the depth and width on the riser pipe shown the Plan Sheet GN-01.
