SW_Review_Comments_22326_98thAveW.pdf Stormwater Review Comments for th 22326 98 Avenue W. 1)No upstream access on the 6 LF of 4 ft dia Detention pipe. Need to have adequate access on the upstream (north) end of the detn pipe. 2)Drainage enters the northeast corner of the property. This drainage needs to be captured and directed into the drainage system downstream of the control structure. 3)As proposed, this drainage system is being connected into the control structure downstream in the plat of Helleren Heights. In order to approve this we will need to know that the control structure for Helleren Heights was sized to by-pass the undetained flows from upstream areas. 4)Please include a note of the unit soil type in the drainage report under the design or description section.
