Purpose of the meetmg was to discuss the potendal <br /> impact tl�e 3team Plant could have on Bceing Lake. A 3096 set of design documenis had <br /> been fumished to the Ciry of Everett for review and with thc compleuon of thc 6090 <br /> documenis,addidonal concerns wartanted a�view of the changes. I <br /> Sin�e the use of the exisdng ditch as a bio•filvation area could not be used as proposed on <br /> the 30�Ro design documenis, altemate methocls of convol were discusscd. ; <br /> I 1. A determination of the watcr quality would bc requi�d before a direct outfall ro the <br />( lake would be allowed. Since this could vary wuh the potential contaminants, it li <br /> was decided the direct outfall would only be acceptable with the proper wntainment <br /> upstream or if rouung the outfall would allow enough bio-filtrauon to provide the I <br />, necessary protection. <br />� 2. Since the 60R6 design indicates the outfall will be adjacent to the ezisting rip-rap <br /> inlet to the lake, a discussion followed to uy and determine how to modi[y the arca <br /> to provide the proper bio-fllvadun. The drain line could be extended ro the East, <br /> past the rip-rap area,.modify the contour to aliow a swale to be added and redirect <br /> the inlet to the lake. After discussing thc potential cost it was decided this was not a <br />� cost effective solution. <br /> 3. 5uggested open grated trench across road was discussed and it did not appear this <br />'� would provide the proper depth to accommodate the new oiUwatcr separator. <br />� <br /> 1801 Flfth Av�nu�,�ult�900 • s..tti.,w..tiin�tton • asios <br /> (408)8ZS0717 PhoO� (208)824J776 FAX <br />
