Sewer and Stormwater Improvements
Project Update June 27, 2014
SPU held a community meeting Wednesday, June 18 to present information and gather feedback from residents about leading alternatives to improve drainage in the 12th Avenue NW basin (western portion of Broadview), and to improve the function of the sewer system in the Dayton Avenue N basin (southern/eastern portions of Broadview).

Project Update March 24, 2014
SPU continues to plan for improvements to the sewer and drainage systems in Broadview. We are currently evaluating alternatives for sewer solutions in the 12th Avenue basin in western Broadview. Next we will pair leading sewer improvement alternatives with drainage improvement alternatives for this area, which has the highest frequency of sewer backups in Broadview. We are also concurrently planning for sewer and drainage improvements in southern and eastern Broadview (Dayton Avenue basin).
SPU held a public meeting on Tuesday, March 18 to present details about the leading 12th Avenue basin sewer alternatives. At the meeting, we also outlined upcoming project and public involvement opportunities throughout 2014 for this project, and shared recent study results including geotechnical study results and priority areas for drainage improvements.

Project Update October 10, 2013
The following updates provide the latest information about our efforts to improve the sewer and drainage system in the Broadview neighborhood.
Recent draft geotechnical study completed in western portion of BroadviewIn the summer of 2013 a geotechnical study in the western portion of Broadview was completed by SPU’s contractors to gain a better understanding of the hydrology in the area. A good understanding of the groundwater conditions and flows is necessary for SPU to develop effective sewer and drainage solutions. The western portion of Broadview has the highest frequency of sewer backups in all of Broadview. This study was needed because of the high ground water table and steep slopes in this area.
Next StepsSewer and Drainage Options Analysis for Western Portion of Broadview
SPU is analyzing the most viable sewer and drainage solutions in Broadview. SPU is evaluating alternatives for regional and local solutions to sewer backups and stormwater flooding in the western portion of Broadview (named 12th Ave basin, see map). We will examine potential options in terms of cost, time to implement, potential effects to residents during construction, environmental benefits/impacts, and other key factors. As we analyze alternatives, we will work with the community for input on recommended solutions. We anticipate beginning design for these capital improvements in the 12th Ave basin toward the end of 2014. We are currently projecting to break ground on the capital improvement project in Broadview in 2016.
Sewer and Drainage Options Analysis for Eastern Portion of Broadview
SPU will also be conducting a similar Options Analysis for the eastern half of Broadview (named the Dayton Ave. basin) which will begin after we complete the analysis on the western portion of Broadview. The reason for this timing (as noted above) is because the 12th Ave basin has a significantly higher frequency of sewer backups. Design for Dayton Ave basin sewer and drainage improvements is currently projected to begin in early 2015.
Thank you for your patience during the technical analysis phases of this large capital improvement project. Working with the members of the community, we will build effective long-term sewer and drainage system improvements in Broadview.
September 25, 2012 community meeting
Thanks to everyone who attended the September 25 community meeting about the Broadview sewer and drainage improvement project. SPU shared an overview of the work completed to date and identified potential approaches for improving sewer service and reducing health and safety risks related to stormwater flooding in the area.
