The hundreds of slabs of concrete overlay that dislodged in Santa Monica Canyon Channel during heavy rain in February do not need to be replaced, according to L.A. County Public Works.

“Los Angeles County Public Works recently completed a comprehensive assessment of the Santa Monica Canyon Channel and determined that it is functioning as intended and remains structurally stable,” said Elizabeth Vazquez, a public information officer from Public Works. “The channel continues to safely convey storm flows and provide its intended flood protection for the surrounding community and nearby properties.”

The concrete overlay, which was installed in the 1970s, broke free during intense rainfall and clogged the channel on Feb. 16, which reduced the channel capacity by about 15 percent, according to officials. After the rains ended, crews completed the removal of the dislodged concrete, which had mostly piled up in the channel between Mesa Rd. and Channel Ln., by Mar. 16.

More heavy rains are anticipated in the coming months due to the predicted El Niño weather system, and, in order to ensure that the remaining concrete overlay does not dislodge, it will soon be removed by Public Works.

“While the assessment confirmed there are no immediate safety concerns, L.A. County Public Works has scheduled proactive maintenance to remove the remaining concrete overlay in the coming weeks,” Vazquez said. “This work will ensure the channel is ready for the upcoming storm season.”
