The percentage noted is the percent of the FY20 capital budget by dollar amount. Obviously the largest portion of the program is comprised of SSO projects. This makes up 58% of the program for about $202 million dollars. The next few slides will provide descriptions of the various project types and review some of the program highlights from this year’s capital program. 5 stormwater design projects totaling $4,275,000 have been removed from the Stormwater category, due to the No vote on the stormwater capital rate this month. This slide represents a location map of all projects planned for FY 20, as well as contingency projects that could potentially happen in FY 20 should budget and schedule allow. This same map and the index matching the page numbers with the corresponding project name and number can be found on the third page of your supplement, or on the website. Green shading denotes the combined sewer area, located within the 66 square miles of the City and 21 square miles of surrounding area Red represent wastewater projects, with circles representing FY 20 projects and squares representing contingency projects. Blue identifies stormwater projects, again with circles for the planned FY20 projects, and squares for the contingency projects. The table at the top left hand corner identifies projects performed throughout the District. Cherokee Street Sewer IR on right, Koeln Combined Sewer IR on left Construction on this project began in May of 2016, with completion projected for September of 2020. The photos show a shaft which is being constructed as a part of this project, the depth of the shaft in these photos is about 75 feet below the surface. The Maline Creek storage facility will run generally under Riverview Drive, from Chain of Rocks Drive to Church Road. The Maline Creek project will divert the excess water and sewage from two CSOs to the storage facility during times of significant wet weather. A pump station will then transfer the stored flow back to the system when the wet weather subsides. The flow will be treated at the Bissell Point Wastewater Treatment Plant. This project is in the Maline watershed. Construction on this project began in May of 2016, with completion projected for September of 2020.

This project is in the Maline watershed. One of the major projects beginning construction this year is the replacement of the Lemay No. 3 Pump Station. These are examples of the projects built under the CSO Green Infrastructure Program. Green Infrastructure, or Rainscaping, includes a combination of vegetation, engineered soils, permeable pavements, and rainwater harvesting that are incorporated into the environment to reduce and manage stormwater runoff near its source rather than quickly entering sewers. To date, $31.7M has been appropriated for this effort. Of this amount, $19.8 M has been spent, and $11.9 M has been committed to future projects. One of the major projects receiving supplemental appropriation in fiscal year 19 for ongoing construction work, is the Jefferson Barracks Tunnel (Lemay WWTP to Martigney PS) project. This project consists of the construction of 17,000 feet of 7 foot diameter deep tunnel. Another major projects receiving supplemental appropriation in fiscal year 20 for ongoing construction work, is the Deer Creek Sanitary Tunnel (Clayton Rd to RDP) project. This project consists of the construction of 22,000 feet of 19 foot diameter deep storage tunnel. Photo: The photo shows construction staging and shafts at the downstream end of the project near Interstate 44, tunnel, and tunnel boring machine. This chart shows past and planned SSO removals by calendar year. The calendar year 2018 total reflects removals from past fiscal years’ construction projects that were completed in calendar year 2018. The SSO removals previously noted in the SSO projects summary are for construction projects starting in FY20, and those removals will be accomplished in later calendar years once construction is completed. We are progressing towards the goal of having no more than 33 constructed SSOs remaining on Jan. 1, 2024, per our obligations under the consent decree. We removed 13 SSOs in calendar year 2018. In calendar year 2019 we expect to remove a total of 5 SSOs. The SSOs removed in calendar year 2018 are: 03/09/18: BP-222 03/09/18: BP-516 04/02/18: BP-086 05/16/18: BP-617 05/21/18: BP-471 05/23/18: BP-610 05/29/18: BP-305 07/20/18: BP-401 07/24/18: BP-456 07/25/18: BP-419 08/15/18: BP-435 10/01/18: BP-289 10/18/18: BP-619 meters provided flowmeter data for regulatory purposes, as well as pre and post construction data for more than sixty projects. The data from these meters, and subsequent modeling efforts, have resulted in the elimination of, or reduction in scope of projects, saving the District design and construction costs. The data have also been used to verify the existing scope of many other projects. 16 storm sewer, and 4 bank stabilization projects.
