HARLEM-BADEN RELIEF PHASE IV |
 |
|
The Metropolitan St. Louis Sewer District’s Harlem Baden Relief Phase IV (Hebert) Project has nine construction packages proposed to relieve wet weather-related overflows in the Bissell Watershed. The Harlem Baden sub-watershed encompasses approximately 300 acres within the Bissell Point Service Area and has a long history of street flooding, yard flooding and basement back-ups which have extremely negative impacts on the lives of area residents. The overall goal of the project is to alleviate the flooding by soft separating the stormwater from the combined sewer flows that emanate from the residential, commercial and industrial buildings in the watershed. The watershed and project area are located within the boundaries of the City of St. Louis, the Village of Hillsdale and the City of Wellston. The District anticipates completion of the soft separation of the combined sewers in the watershed within 10 to 15 years.
CDG is the prime consultant under contract with the District to provide the design on Package 5, (Darver to 69th) and Package 6, (Hodiamont to Cherry Trunk Sewer B). Both projects will separate the storm flow from the combined sewer to reduce the sanitary backups, increase capacity and alleviate flooding. A new “storm only” sewer will be constructed that will tie into a downstream storm sewer that has previously been constructed in a prior package. The storm sewer trunk leads to a regional detention basin, near the intersection of Clara Avenue and Hebert Avenue, which was constructed around 2012. Package 5 runs through a completely built out residential neighborhood with a small amount of industrial development and has approximately 8,000 linear feet of new storm sewers varying in size from 12-inches to 48-inches in diameter. Package 5 is in the Design Completion Phase and will hopefully be constructed in 2022-2023.
Package 6 crosses several industrial properties, as well as a salvage yard and a manufacturing facility. A section of the Terminal Railroad will also be crossed. Package 6 has approximately 6,500 linear feet of new storm sewers varying in size from 12-inches to 84-inches in diameter with over 1,000 linear feet of pipe in tunnel. Package 6 is currently in the Plan Review (60%) stage and will be entering into Design Completion Phase soon, with the design period ending in late 2021.
Preliminary Construction Cost Estimates for Packages 5 and 6 are approximately $5 Million and $11 Million respectively.
CDG assembled a highly qualified team for this effort that includes Engineering Design Source, Inc., Civil Design, Inc., TSi Geotechnical, Inc., Gresham Smith, Inc., Geotechnology, Inc., Precision Daylighting, Inc., and Vector Communications. Almost all of the subconsultant partners have worked on previous packages of the Harlem-Baden Relief Project making our team intimately familiar with project details and site conditions.

WELCOME BACK PARTY |
By now you know our employees and their happiness mean a lot to us. What you may not know is that we asked them to come back to the office full-time beginning June 1. As a token of our appreciation for their hard work and flexibility over a tremendously difficult year,
CDG’s Employee Relations Committee organized a welcome back party for each office. In St. Louis we enjoyed a night in the courtyard catered by The Gramophone. We sipped local brews from 2nd Shift Brewing, 4 Hands, Schlafly, Perennial and more.
In Sheridan, Mark Ree, Maggie Morneau, Tyler Reed and Ron Destefano played a round at Hidden Hills Golf Club. Afterward, they grabbed dinner and drinks at Mydland Market, Sheridan’s newest neighborhood restaurant.
In Charlotte, Scott Terry, Seth Inhofer and Steve Simpson spent the afternoon hitting golf balls at Topgolf. As you can see from the photo below, there were plenty of drinks and food to go around.
