In-Construction Stormwater Projects
Saylor/Swain/Vallette Stormwater Improvement Project
In an effort to further investigate large-scale infrastructure improvements, the City hired CBBEL to complete conceptual engineering analyzes. Because the infrastructure improvements would require increased pumping along Salt Creek (Creek), City staff and CBBEL staff met with DuPage County stormwater officials multiple times. Pumping more water into Salt Creek would not be allowed by the County unless mitigation would occur with the project or if the increased pumping would not raise flood elevations downstream on the Creek. CBBEL completed the County’s requested stormwater modeling and the County reviewed the submitted information.
Additionally, in 2018, CBBEL completed a topographic survey of both McKinley Avenue and Crescent Avenue, between Swain Avenue and Sunnyside Avenue/Rex Boulevard, which would be the likely “route” of any future infrastructure improvements between the problem area and the Creek. CBBEL staff then reviewed the survey data, defined the best and most cost-effective route, and analyzed the cost estimates.
City staff and CBBEL staff then presented the findings to the Public Works and Buildings Committee and the City Council in 2018 and 2019. Because of the excessive cost of the large-scale infrastructure improvements the City began to seriously consider residential property buyouts for neighborhood detention as an alternative. Over the course of 2019 the City was able to acquire 5 properties in the neighborhood. The City then hired CBBEL to complete engineering design.
