Council updates dredging progress and lake-depth mapping; insurance renewals pending
Summary
Councilmember Chip Zimmer reported dredging at Treasure Island back channels is under way at a cost of $36,000 (dredging fund), work is only partially successful (50–70%) due to excavator limitations, and lake depth mapping continues; he also briefed the council on pending July 1 renewals for UST and cyber insurance.
Councilmember Chip Zimmer reported that dredging work has begun, focused on Treasure Island back channels, at a cost of $36,000 funded from the dredging fund. He said the operation is achieving roughly 50–70% effectiveness because the excavator’s weight and reach limit access, and that an extended‑arm machine is being used with increased equipment‑sinking risk.
Zimmer also provided an update on a lake depth‑mapping project: deepest areas were mapped, shallower areas remained inaccessible, and with the snow gate closed water levels are expected to rise; a tentative follow‑up review was scheduled for April 23. Zimmer additionally noted two pending insurance renewals effective July 1—UST coverage likely to stay with Great American and cyber insurance currently with Tokio Marine, with brokers asked to seek comparable or improved rates.
