An emergency project to replace a 50-year-old pipe in a culvert in the Avila Fire burn scar area is underway.
The original pipe was 36 inches, while the new pipe is 28 inches, according to Caltrans crews.
Caltrans officials say crews conduct maintenance work at the culvert year-round.
"We have a camera crew that goes through cameras, so whenever they see a failed area, that's when we have to come in," said Robert Bonilla, field inspector for Caltrans.
Crews began the emergency project on Monday. Caltrans officials expect completion of the project in two weeks.
