Auburn Way South Flooding Improvements, Phase 2 - Project CP1202
The intersection of Auburn Way South (AWS) near the SR 18 underpass frequently floods during large and/or intense rain events. The low-slope, gravity storm drain adjacent to the underpass provides limited capacity for upstream tributary flows. A combination of trunk line improvements and installation of a pump station has provided some benefit, but has not alleviated all the flooding at the depressed underpass. The downstream drainage system is also capacity-limited causing a "recirculation" of the pumped discharge, thereby limiting its effectiveness during large rain events.
The Comprehensive Stormwater Drainage Plan (2009) identified a two phase project to reduce stormwater flows to AWS at SR 18 by diverting upstream flows from the impacted area. The total 25-year flow to be directed away from AWS is being estimated at 10 cfs. Water would be redirected by gravity flow at AWS and 17th Street SE, toward the existing stormwater ponds located at 17th and A Streets SE, and 21st and S Streets SE. Final modeling will be conducted by the City's on-call modeling consultant to determine pipe size and slope.
Phase 2 will intercept all flow from the diversion structure at AWS and 17th Street SE to the west. At the intersection of K Street SE and 17th Street SE, a new flow control structure will in installed to maintain the current discharges pattern to K Street SE. From this point west, approximately 3,100 LF of 24" - 30" pipe will be required to replaced the existing lines in 17th Street SE. The existing pipes along 17th Street SE at the intersections of J Street SE and B Street SE will be plugged, diverting existing flows away from AWS. Eliminating the discharge into these two pipes will add 4.5 cfs to the 17th Street SE line. Inlet spacing along the project shall be considered to meet design standards. This project also includes deepening the existing pond, and modifying the outlet control structure at 17th Street SE and A Street SE to gain an additional 7 acre-feet of storage. Once complete, the diversion structure at 17th Street SE and AWS will be modified to prevent flow to Auburn Way North.
