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.

Construction for this project is anticipated to begin in early 2015 and be completed by 2016.

For more information on this project, please contact Seth Wickstrom, Project Engineer, at 253-804-5034.

Sewer Pump Station Improvements - Project CP1208

Construction is anticipated to start in October 2014 and to complete in April 2015.

For more information on this project, please contact  Joel Chalmers, Project Engineer, at 253-804-5063.

Valley AC Main Replacement - Project CP1219

The purpose of this project is to improve system reliability and reduce distribution system leakage. This project will replace approximately 2,860 linear feet of 6 inch and 8 inch existing asbestos cement (AC) pipe with 8 inch and 12 inch ductile iron pipe and the associated gate valves, fire hydrants, water meters, service lines and other appurtenances along streets in the Valley service area. In addition, this project includes abandoning approximately 2,620 lineal feet of 6 inch asbestos cement water main along Auburn Way North. The fire hydrants and service lines currently served by this main will be connected to the existing 12 inch ductile iron pipe along the east side of Auburn Way North or to a new 12 inch ductile iron pipe along the west side of Auburn Way North.

The project is anticipated to be under construction in the Fall of 2014.
