At this evening’s conference call with the Incident Commanders, we learned the following things:
During today’s rains, there were no injuries, no damage and no reportable incidents attributable to flooding, mud or debris flows
None of the debris basins breached their capacity today

The Weather Service is indicating that there is another band of showers expected to arrive in the area around 11 pm tonight and it will be followed by a trailing cold front that is expected to produce thunder storms and showers with the potential for rainfall amounts at times up to 2 inches per hour
Today’s rainfall as measured in LaCanada/Flintridge was approximately 0.72 inches today

All debris basins are draining and all inlet structures are being monitored 24/7 and cleared as necessary
Crews from the Department of Public Works will continue to work to clear the mud and debris from the basins and inlet structures through the weekend, or as long as necessary

While there are evacuation orders in place for La Crescenta, LaCanada/Flintridge and Acton, there are none in effect for Altadena except the Millard Canyon Campground
There is still a possibility of additional rainfall on Saturday
There are no further road closures for Altadena, except the one in place at the Chaney Trail gate

The news for today was better than all of the agencies planned and prepared for.

We owe our thanks to Supervisor Antonovich and his staff for making sure that information is being made available to all of us and for making sure that the communication and sharing of information among agencies is working well, and we owe all of the agencies our thanks for being ahead of the incident and for keeping us all safe.

Updated information on the status of the debris basins should be updated around 8 am tomorrow by the Department of Public Works.  You can find that information at www.dpwcare.org.
