The Newport Beach City Council will vote next week to approve a work contract to clean toxic deposits from the Rhine Channel in Lower Newport Bay.
If approved, the project will dredge four to eight feet deep into the channel, Harbor Resources Manager Chris Miller said.
The Rhine Channel will be the first in a series of cleanup efforts. The city hopes to remove contaminated sediment from the rest of Lower Newport Bay in the next three years, Miller said.
The estimated cost to the city for the cleanup of the Rhine Channel is $4 million. The rest of lower Newport Bay may cost up to $20 million, although the costs are expected to be covered by federal funding, Miller said.
