does not bypass the oil/water separator (see attached <br />photocopied page). <br />The natural "discharge�� point for runoff fr.om much of the <br />adjacent property to the south is sheet flow onto this <br />property. Sometime in the future, they will need to <br />discharqe their runoff somewhere. The swale along the <br />southwestern portion of this site is c�llecting some of the <br />sheetflow. liowever, an easement should be provided from <br />catch basin 11 to the existing drainaqe easement to allow <br />future developers of the property to tie into the system on <br />this site. It may also be appropriate to stub a pipe out <br />into the existing easement to avoid future disruption of <br />Washington Natural Gas facilities. Along these lines, the <br />current runoff from the adjacent site for the 5 year storm <br />(the probable desfgn storm for the detention system) must be <br />estimated and the lower swale analyzed to be sure it would <br />continue to meet City design standards if or when the flow <br />from the adjacent property was added. Modification of the <br />detention pond outlet structure is not necessary. <br />Many of the circled pipe crossing call-outs are not <br />"attached" to anything. <br />Details on the containment vault, such as sizing, valve <br />requirements, etc., must be submitted and approved before <br />these plans can be approved. <br />Cross-section arrows are not labeled (i.e. A-A). <br />
