1 <br /> Intermec/Kenilworth Hills Stormwater Analysis Everett, WA <br /> minutes). This is whyonlythe return frequency and not the duration of the <br /> q Y <br /> storm was given in the underlying drainage condition -the storm duration <br /> ' was inherent to the method used to calculate the release rates and detention <br /> volumes. <br /> At this point, you may wish to route the 25 year, 1 hour storm through the <br /> detention facilities and see if the underlying detention condition can be met with <br /> the City's current standards." <br /> This report provides a stormwater analysis of the 25-year, 1-hour storm event through the <br /> proposed pond for Intermec Lot 2, the existing Intermec Lot 1 ponds and the Kenilworth <br /> Hills No. 1 pond. This analysis shows that the development of Intermec Lot 2 would not <br /> create a peak flow out of the Kenilworth Hills pond greater than 0.5 cfs. <br /> ' If either of these analyses showed deficiencies, the City of Everett would require the <br /> stormwater management facilities for Intermec Lot 2 to be designed to the 2005 <br /> Washington State Department of Ecology Manual (DOE Manual). However, since this <br /> report shows that (1) Edgewater Creek has adequate capacity and (2) the development of <br /> Intermec Lot 2 utilizing the 1992 DOE Manual does not create a 25-year, 1-hour peak flow <br /> of more than 0.5 cfs from the Kenilworth Hills #1 pond, Intermec Lot 2 can be designed <br /> utilizing the current City of Everett requirement of the 1992 DOE Manual. <br /> I <br /> 111 <br /> I <br /> I <br /> I <br /> 1 <br /> 1 <br /> 1 <br /> PACLAND Job# 50175001 Page 2 <br />
