City removes one stormwater project after MSD review; CSO Mary separation now scheduled for 2026
Summary
Public works staff reported MSD concluded one bid‑package site (Park Ridge/White intersection, Site 352217) would offer limited hydraulic benefit because it connected to an overloaded combined sewer; the larger CSO Mary separation project is expected to start Sept. 1, 2026, and may not resolve overland flooding at a low‑point home.
Public works staff reviewed progress on a stormwater bid package and relayed MSD’s hydraulic evaluation of one parcel, Site 352217 (Park Ridge/White). MSD concluded that constructing the planned inlet and pipe connection at that site would connect to an already overloaded combined sewer and therefore would provide little mitigation for the existing problem. MSD advised the city that separation work tied to the larger CSO Mary project — separating sanitary and storm systems — would affect the area but is not expected to remove overland surface flow to a low‑point property. Staff said CSO Mary’s construction is tentatively scheduled to begin Sept. 1, 2026, and will take about 3½ years because it covers multiple neighborhoods.
Public works staff recommended dropping Site 352217 from the immediate bid package; removing it would free about $82,800 that could be redirected to higher‑priority projects on the list. Aldermen asked staff to press MSD about earlier mitigation options and to cross‑reference the full Gonzales project list with the CSO Mary schedule to identify overlap and opportunities to coordinate work.
Staff noted homeowners at the low point may still face flooding even after sanitary/storm separation and that private engineering and property‑level solutions could be necessary. Committee members asked staff to follow up with MSD about possible earlier interventions and to include cross‑referencing information in ongoing reports to the committee.
Why it matters: The change affects capital priorities and timelines for stormwater work and clarifies limits of relief from the CSO Mary project for certain properties.
