The comments below were generated from this project's City of Everett Stormwater Reviewers.All questions shall be routed through this project's Public <br /> Works Reviewer with City of Everett Permit Services. <br /> # Document Sht/Pg Reviewer's Comment Designer's Response Initials <br /> Review Comments from DEPARTMENT NAME:_Surface Water Management ,REVIEWER NAME:_Erik Emerson <br /> 1 SSP Backwater • Include a labels for the lettered pipes in the <br /> Calculations downstream map. <br /> 2 SSP MGS What do the structures "outfall"and"Null" represent? <br /> Calculations These are large structures,but I'm not sure how they <br /> impact the stormwater design. <br /> 3 SSP Is there any concern that very high tides/storm surge will <br /> impact trees with salt water? Record high tide is well above <br /> the outlet IE of the Filterra device. Include a backwater <br /> valve or ensure (with note on plans) that the selected tree <br /> species is tolerant of occasional saltwater inundation. <br /> (Downstream analysis did not indicate a tidegate at outfall. <br /> If there is one this comment can be ignored.) <br /> 4 SSP WQ sizing Please connect the dots from design WQ flow rate to facility <br /> sizing. I was not able to locate a description of the required <br /> treatment footprint or facility capacity other than a <br /> statement that the treatment vault flow rate is 0.069 CFS in <br /> the text.There is no way to verify that the oil control <br /> design rate was used, etc.A sizing letter from the <br /> manufacturer is also acceptable as long as it states the <br /> design assumptions. <br /> 5 Plans C3.01 Existing CB in SE corner of site is noted to be raised to <br /> grade and solid lid.Why not remove as this does not <br /> appear to be junction or serve any purpose. <br /> Page 2 of 3 <br />
