Los Angeles County Public Works crews have cleared the wreckage basins and storm drains, and handed out sand bags to residents ahead of the heaviest rains from the mid-February storm.
As part of those preparations before the brunt of Thursday’s storm, LA County is working with federal agencies to develop a system that includes debris that could start flowing from within the Pallisard and Etonfire burning zones. . The goal is to contain the flow in the streets and prevent mud, water, rocks, tree branches and other debris from reaching the property.
At a county press conference Wednesday, Los Angeles County Public Works Director Mark Pestralla said that rainfall rates exceed 0.5 inches per hour are due to mud and debris flows depending on the condition of the topography, soil system, geology and flood control system. It said it could lead to. . He works 24 hours a day to ensure that the county’s 154 fragment basins are clear and ready to catch any mud and debris that could cause the mountain’s slopes to crash. He said.
“We’re ready at these facilities,” Pestrala said. “We have the ability to be storm-sized and magnitude of the storm we expect to see come with this storm.”
A system of thousands of miles of K-rail and hundreds of thousands of sandbags will be used to help capture debris before reaching the street, Pestrella said. If so, the flow will be diverted onto the streets and contained in the streets to prevent them from reaching the waterway, which will lead to the oceans in the Pallisard area, he said.
“This is unusual,” he said. “We don’t usually want the wreckage to end on the street.”
It’s raining in there and enough to make today’s roads slippery, but the heaviest rain is still expected on Thursday. The rainfall rate is high, causing great concern about mud and debris flow.
In Altadena, bright green compost filter socks in mesh tubes filled with composted material were placed around the properties to contain dangerous materials. Barriers have also been placed around storm drains to prevent dangerous waste from flowing into the stormwater system. The K-rails were placed on the road, adding another layer of flood and debris flow protection.
Pestrella urged residents who believe they are at risk of contacting the county at 800-675-4357 to evaluate their property. The service is available not only in recent fire areas but also in locations in any county.
“The service will be offered soon to the point that we can no longer reach your property,” he said.
As the system moves west to east and evening to overnight, it rains on Thursday afternoon. During that period, the risk of flood problems and debris flow is highest in wild burn scar areas.

“Recent burn areas from fires at Palisade (Pacific Palisade), Hearst (Silmer), Kenneth (West Hills) and Sunset (Hollywood Hills) have been reported to have been reported to have been reported to have been reported to have been reported to be recent burn areas from debris and water spills that could contain dangerous substances. There is a higher risk of this,” he said in a statement in Los Angeles. “Additional safety messages may be directed towards these areas, especially if you are in areas affected by recent wildfires, be prepared and take extra precautions.”
Flash flood clocks will be in effect in most parts of the area from 1pm on Thursday to 4am on Friday. Flash flood watches show conditions that can lead to flash flooding. Flash flood warnings that could be issued during the storm indicate that flooding is occurring or imminent.
The rain will turn into a shower on Friday and decrease that afternoon.
