SEPA k6596 <br />This memo is written to assure the City of Everett that Wetland Resources, Inc. has been <br />deeply involved in the concept and final design for water quality mitigation for the filling of <br />.98 acres of Can -.gory H wetlands at the proposed HomeBase development site in the <br />Eastmont area of Everett, Washington. Wetland Resources, Inc. has reviewed the Civil <br />Engineering Designs prepared by Barghausen Consulting Engiuoorings for water quality <br />and stone waW detention mitigation and find that titey meet the origtaal intent of mitigating <br />for the lost function of water quality and storm water detention for the filling of the on site <br />wetland. <br />In addition, Jenna Scholz has prepared a Final Wetland water Quality Monitoring Plan, <br />dated October 1997, for the development site, which requites water quality moWtoxi ng at <br />pre -construction, construction and for five years following construction. Monitoring sites <br />are established immediately south of the wetland fill site, in the central on of the <br />existing wetland and below the Skate Deck to the north of the wetland site. Annual <br />reports will be supplied to the City of Everett related to trip activity, sampling results and <br />description of regulatory compliance with water quality criteria developed during the pie <br />construction monitoring condition. <br />Dd9emtoefftolEtancthodel. owgyMateWrr. qeStultaaonleidtykdBsaiaload loshgtaoissrmt,reEwvriaiectewSretddoectkethndetailoeWn, hmataeistir gbQaetieunoanliitynfovroMrlhvooendfiiltti'olitrnintghgoe fPptlhWainsi <br />isPr!asses Scholz and has verbally indicated, tiirec'1y W me, that he plans on <br />Department of Ecology 40l Water Quality Ceiti9eadon within the next few <br />days. <br />In my best professional opinion the implementation of the planned water quality and storm <br />water detention facility, for the IlomcBase - Everett development, will replace the pre <br />existing functions for water quality and storm water detention supplied by this .98 acre <br />wetland. The plan is described in the approved Civil Fngineedng Design prepared by <br />Barghausen Consulting Engineers, along with the Water Quality and Storrs Water <br />Zmtention Midgation Analysis revised July 28, 1997 and prepared by Wetland Resources, <br />and the Pint Wetland Water Quality Monitoring Plan prepared by Jenna Scholz and dated <br />Ortobor 1997. <br />Cordialuy, r� <br />wil.'iam tgailcott <br />Certified Professional Wetland Scientist <br />
