DPW reports on heavy-rain flooding, urges residents to use claims process and mitigation options
Summary
Department of Public Works told the committee that intense, short-duration storms caused street flooding and some sewer backups; staff described immediate response steps, longer-term resiliency projects, and options for homeowners such as Palmer valves and the city claims process.
Department of Public Works staff told the Improvement and Services Committee on July 1 that a heavy storm a week earlier and additional storms this week produced rapid, localized street flooding and isolated sewer backups across Green Bay.
Staff said most flooded streets drained within hours, though some areas required longer cleanup. They described ongoing maintenance work, a pilot lateral-replacement program tied to street reconstructions, and flood-resiliency projects intended as longer-term improvements. "When you get a storm like this, there's really not ... there's nothing you can do at that point in time," a DPW presenter said, explaining that sewers could not be practically sized to handle the most extreme short-duration events.
Committee members asked how residents who have flooded multiple times should respond. Staff recommended using the city's online claims process for damage reports and urged residents to call DPW while flooding is happening so crews can inspect sanitary mains. For sanitary-sewer backups, staff noted private measures such as installing a Palmer valve can prevent sewage from backing into basements; for surface-water yard drainage, options include regrading or installing area drains.
Members also described specific local impacts, including a city garage and a fire station that experienced flooding. Staff cautioned about safety hazards such as floating manhole covers and urged residents to avoid driving through floodwaters.
The committee thanked staff for the rapid cleanup work and asked DPW to continue public outreach about how and when to file claims and to report on progress of pilot and resiliency projects at future meetings.
