Council hears stormwater projects, flood‑reduction pumps and smoke‑testing plan
Summary
Staff described stormwater capital projects including a pump and floodwall project near Eastgate/Par Building, portable pumps, and a smoke‑testing program to locate sanitary sewer defects that can allow pollution to enter storm drains and waterways.
City stormwater staff presented planned capital work July 15, focusing on flood‑reduction measures at the Eastgate/Par Building area, new portable pumps and a smoke‑testing program to identify sanitary‑sewer defects.
Staff described a multi‑phase plan to clear sediment, repair pipes and install a storm pump and flood walls in a low‑lying block near 40 Ninth/50 Third Street (the Eastgate area). Staff said recent heavy rain showed the improvements working as planned in normal flows but noted that when river levels are high the system will need pumps to move water past the berm.
Staff also said a portable diesel generator and additional large storm pump are budgeted for deployment to critical subbasins, and that the city will continue smoke testing of sanitary systems to find defects where groundwater or stormwater can bypass treatment and enter sewers. Staff said smoke testing uses contracting engineers who produce maps and notify the public when testing occurs, and encouraged residents to report smoke sightings when testing is publicized.
Ending: Staff will proceed with design and environmental work for the Eastgate pump project and will return with construction timelines and project resolutions; smoke testing will continue as a tool to prioritize sewer repairs.
