Personal Observations

Saturday, 2/6/10, 1:50pm - Drove around and checked a lot of spots out.  Stonehouse still looks good.  Auburn debris basin is at about 5% capacity, I'm told.  One Carter looks good.  Went up to lower canyon, and there were crews and residents working in the road just above the bridge by Mary's Market.  I've got some pics I'll be uploading.  I'm told that the mud came down from Yucca Trail.  When I walked by Yucca, it was pretty clean, I was surprised to hear that's where the mud came from, but it was SMPD that told me that.  I talked to Elisa Weaver, the City's Public Information Officer, and she told me that the debris basin at the top of Yucca Trail is pretty much at capacity, and it will take eight to nine hours till they can clean it out.  So cross your fingers.  I asked what happens if it hits capacity and overflows?  She said we'll probably lose some structures, so people really need to heed the City's call for evacuations.  As to the evacuation, there are about 270 homes currently under mandatory evacuation, with an emergency center set up at the Rec. Center, 611 E. Sierra Madre Blvd.  Surprisingly, there's nobody there except staff.  According to Elisa, there's been no major structural damage, though obviously some homes and garages have gotten some water and/or mud inside.  The Fire Dept. made a rescue this morning, freeing somebody that couldn't get out of their house.  No injuries, so far, though.  National Weather Service says we have 100% chance of rain this afternoon (hasn't been raining for a while), and 80% chance of showers tonight.  Crews are working up at Skyland, which had some pretty severe mud flow (the most I've seen in the couple years I've been covering things, but that's only 8 or 10 storms.  I've got some pictures I'll be posting in a few minutes.

PEOPLE - Bailey Canyon and the Mt. Wilson Trail ARE CLOSED!!  I went by Mt. Wilson Trail and somebody had torn down the caution tape.  One of the Trail Race winners from an earlier year was coming down off the trail, and while I was there, a woman with her dog started up the trail.  Use your head...If the rain starts, you're in danger if you are on those trails.  And even if it's not raining...it could be that there's something blocking a bunch of mud or water above you, that suddenly shifts and no longer is able to hold it back.  And then you're in its path.  I understand that happened locally about ten years ago and two people were killed.  STAY OFF THE TRAILS!!

Here's the pics (click to enlarge):

This is "upstream" a ways from Mary's

The dam

This is looking up Yucca Trail toward the debris basin.  Hard to believe this is the source of the mud, it looks so clear.  Wondering if SMPD might have got some bad info...

Looking down Skyland from 801, toward Fern

 

Saturday, 2/6/10, 8:30am - Just saw a post on Facebook that there are sirens in the canyon, following a downpour of 1/2" rain in ten minutes.  Unfortunately, I have a Chamber-related meeting at 9:15 that I'm getting ready for, which prevents me from checking it out.  Following the meeting, I'll head up and see what I can see, and post a report here.

Saturday, 2/6/10, 6:30 - Mud Update  I just took a look around, and with the exception of the mud in the road at Skyland, most everything seems to be clear.  There’s some mud in the road at Stonehouse above Grand View, but not enough to close anything down or cause any damage (yet).  Stonehouse is barricaded on the south side of Grand View.  There’s a little dirt in the road by the bridge above Mary’s Market, but otherwise everything in that area seems clear, Alta Vista, Yucca Trail, etc.  Went to the end of the road, no issues.  One Carter is clear at both driveways. 

I think I may have misreported something in my 5:05am update, when I said that the resident at 801 Skyland was evacuated.  I think what was said was that they were put on voluntary evacuation, not that they were evacuated (it was 5am and I had just woke up).  Now that I’ve had a cup of coffee and gone by and seen all the upstairs lights on at 6am, I’m thinking, I’ve seen lots more mud there and they didn’t evacuate, so I think I just misheard the watch commander.

Stonehouse above Grand View, 6:01am

1 Carter above Baldwin, 6:06am

East end of 1 Carter, 6:07am

801 Skyland, 6:20am

2/5/10, 10:45pm - Just went and checked on Skyland, and it's clear as a bell.  Since it's usually the first place to have issues and there weren't any issues, I decided not to bother checking other places.  However, 1 Carter was kind of on the way home, so I drove by there, and the streets are clear there, as well.


My Observations

How It All Started City Stuff Online Resources SM Mud/Debris Flow Incidents

Santa Anita Fire - 4/26/08

Less than 3% of the predicted ten year storm mud-flow is expected to come from the One Carter property, some of which was denuded by fire, and some by the developer.  So the development at One Carter was also a (minor) contributing factor to the potential mud and debris flow problems the City is facing.

Map of Potential Mudflow Area, Phase I - Definition of Phase I

Map of Potential Mudflow Area, Phase III - Definition of Phase III

Evacuation Area 1 - Santa Anita west to Camillo, evacuate to SM School Upper Campus

Evacuation Area 2 - Lower Canyon, evacuate to SM School Upper Campus

Evacuation Area 3 - Upper Canyon, evacuate to SM School Lower Campus

Evacuation Area 4 - Mountain Trail west to Auburn, evacuate to SM School Lower Campus

 

Phase I = Small isolated debris and mudflows possible at specific locations.  Streets may be flooded or blocked by debris.  Reports of debris on private property may be received.  Few, if any, structures may be endangered.

Phase II = Moderate debris and mudflows possible at more widespread locations.  Some streets may be completely blocked by debris.  Depending on location and terrain, some structures may be endangered by debris and mudflows.

Phase III = The potential exists for significant debris and mudflows to be widespread over specific areas.  Streets may be blocked and considered unsafe for travel.  Many structures could be endangered by debris and mudflows.  Extreme caution should be exercised below uncontrolled canyons due to sudden debris and mudflows.
