The project was reviewed under the assumption that all stormwater systems are to be owned and maintained <br /> by the Port of Everett.The conveyance system specifically is designed to a previously agreed to standard which, <br /> in some aspects, is a lesser standard than would be applied for City owned and maintained facilities. <br /> 2. The provided plans were reviewed in conjunction with the Waterfront Place Central Phase 2 and 3 Development <br /> Hydrologic and Hydraulic Report, PND, December 2017.This report was originally submitted as a "for reference <br /> only" document.The calculations for the specific area included in the SE Millwright Loop and Open Spaces <br /> submittal were reviewed and found to be consistent with the agreed project standards.At the completion of the <br /> greater Waterfront Place Central Development a final stormwater report will be required for review,approval, <br /> and archiving by the City. <br /> 3. Ecology's GULD approval for the Linear Modular Wetland requires that each installation be reviewed by the <br /> manufacturer as noted in the approval Conditions of Use: <br /> 2. Each site plan must undergo Modular Wetland Systems, Inc. review and approval before site <br /> installation. This ensures that site grading and slope are appropriate for use of a MWS—Linear Modular <br /> Wetland Stormwater Treatment System unit. <br /> Please provide documentation that the system has been reviewed and accepted by the manufacturer.The <br /> review should address the fact that the treatment media will be regularly inundated and the fairly significant <br /> bypass flows which appear to be being handled by the internal bypass system. <br /> 4. Please add design treatment and bypass flows to the Modular Wetland table on sheet C3.05. <br /> grr CELEBRATING Erik Emerson PE <br /> 125 Senior Surface Water Engineer I Public Works <br /> YEARS P:425.257.89951 3200 Cedar Street, Everett,WA 98201 <br /> A story worth telling everettwa.gov/publicworks I Facebook I Twitter <br /> Note:Emails and attachments sent to and from the City of Everett are public records and may be subject to disclosure pursuant to the Public <br /> Records Act. <br /> 1 <br />
