Neighbors in Makiki are happy to see city crews hard at work clearing vegetation and silt built up in Makiki stream.
They're scared of what happened in 2006, when the stream overflowed trapping residents in their homes and tearing down walls along the stream.
"The water basically ran through my house. We became the Makiki Stream basically, and it was total chaos, total chaos," said Makiki resident Raymond Lalosin.
"We are thinking it might happen. It's basically just brick and mortar, it can collapse again and if it collapses again, it will go on the street once more," said Makiki resident Spencer Lau.
To them it's just a matter of time before the stream over flows again during heavy rain. Those living in the area say the dredging is years overdue.
"Endless emails, contacting politicians, department heads, state and city a like. This is the end result, you got to be persistent to get something done," said Lalosin.
Parts of the stream are clear, but there are still many areas full of vegetation blocking the flow of water. The view of miles of silt and vegetation is keeping neighbors unsettled.
"There are homes that sit along the stream, anyone can be home when the next big storm happens, and if they get flooded again someone could get hurt," said Lau.
The work is expected to take at least months.
