There was less than 3500 sf of <br /> impervious area on the site at that time,therefore,only minimum requirements 1-5 are required for the project. <br /> Do not connect roof downspouts to side sewers or laterals, use splash blocks(route first through landscaped area, <br /> where feasible)and sheet flow to the storm drain system. <br /> The drainage in the right of way needs to be directed to the 12"separated storm drain line in the 33rd/McDougal <br /> intersection (preferred)or across the street to the 8"SD in McDougal. Revise the alignment and profile of the proposed <br /> storm drain in the right of way,as needed, so that it discharges to the existing SD. Do not discharge the proposed storm <br /> drain to the combined sewer in McDougall, and do not discharge it to the private drain line from the •roperty. <br /> Catch basin#4 and #6 should be revised to be inlets per COE standard drawing 401. Reduce the number of structures in <br /> the ROW, if feasible. <br /> r <br /> f <br /> A floatable material separator structure shall be 'rovided, per standard drawing 413 or 414, as the last structure on the <br /> drainage line coming from the parking lot and privided in the ROW prior to discharging to the combined sewer. <br /> Also,their survey shows that the drain line at th south side of the property is on their property and not the neighbor's <br /> property to the south. This differs from what is spawn in our GIS(the GIS shows the property line farther north).As long <br /> as their surveyed property boundary and drain location is correct they will not need an easement to connect to it. <br /> Also, I noticed they are connecting to a wa erline\behind the sidewalk,on the opposite side of McDougall. Our GIS <br /> shows the water behind the sidewalk is a 4s" tran mission main and the 8" DI main is in the north bound lane. If the <br /> water department hasn't already commen -d on t S is,we will want to confirm they are connecting to the right water line <br /> here(!) <br /> 7 -2.6" -17 <br /> Thanks, _ <br /> C�mc� / <br /> Arnie Roshak, PE <br /> City of Everett Public Works Neel C® ie el4r1(I At, -h--0 yl' <br /> 3200 Cedar St / / �,l'/ - <br /> Everett,WA 98201 L e/s ,s6e z ?C egse. <br /> Direct:425-257-7249 <br /> Fax:425-257-8882 <br /> ARoshak@everettwa.gov /(;i't <br /> 1 <br />
