The $2-million Buck Gully erosion control project is nearly complete and already has proven to work as intended, slowing down this spring's storm waters that streamed toward Little Corona Beach.
But some neighbors along the gully say the system, which uses rock-filled cages to slow and divert water flow, might be creating an unintended problem — stagnant pools of water that could harbor mosquitoes.
"The water is starting to turn green, and I'm afraid it'll be a mosquito farm," said Sandie Haskell at the April meeting of the Corona del Mar Residents Assn. board.
Robert Stein, an assistant city engineer who oversaw the Buck Gully project, promised to visit the site.
Later, in an email, he said there were "no signs of mosquito larvae."
"The contractor has made some adjustments and the water is flowing better," his email said.
But Haskell and others who live along lower Buck Gully remain concerned.
