Thank you for a thought understanding of what actually happened in Montecito. I’ve seen too many articles and comments already from people applying their own agenda on “how the soil must be taken better care of”, to the “mudslides will just continue to damage houses in California”. This was an event of very strange circumstances that had to do with voluminous hydraulics combined with the after affects of a ravenous fire.

Please don’t take the 166, take the 46!!!! The 166 is too dangerous!!! Thank you for writing this.

I am the gardener for Penny and Adam Bianchi, 1721 East Valley road. You list the three buildings on their property as destroyed, as have others. Their daughter has been to the property twice to rescue their cats. I can email you photos that show the house very much untouched by any mud or water. Their guest house and garage did have some water and mud, but are intact.

Thank you very much. This is very informative. Your hours and hours of research and compilation are most appreciated. 🙂

I have 2 questions.
1. We have flood control professionals, we have professional geologists, we have professional meteorologists. Wasn’t there a team of them who could look at a worst case scenario and say: evacuate people from these areas?2.And here is a post I sent to Tracey Lehn of KEYT: Hi Tracy, I’ve been frustrated with the general shallow coverage of the 101 closure. How about the old: WHO in in charge, how many workers WHAT is their plan, the problems they are encountering, what they are doing to mitigate those problems WHERE is this all happening (get a AAA map, blow it up, put a red marker on where the mud is and WHY have they missed two previous deadlines, why is it taking to long, why is there not an army of personnel and equipment on the scene. It is my view that Caltrans would take a supervisor, quality engineer, two watchers and one engineer to drain a bathtub. How about some real reporting on this issue. It is both nuts and unacceptable to have this road closed for 2 weeks…. just nuts.
Your thoughts would be appreciated.

The one thing I realize, after the fact, is that the sheer size of the brush was also reflected in the size and depth of the roots.
Many slopes in areas above the developments hit with debris flow have what geologists term “nested boulders”, as well as what they call “floaters” Both are strictly held by the mantle of soils which also has the brush growing in it.
I recall walking up through some remote areas of the Gap fire in 2009 and looked with a strange kind of concern that was not cognitively based, at the holes left where big stands of toyon and laurel sumac has been. Intuitively I felt a problem was represented there, but cognitively I really didn’t put it together.
Now it is clear.
The super dry conditions and low humidity caused the fire to burn into the soil to the ends of the roots. With the root ball cavity there acting a a sump, the roots were a conduit into the deeper mantle.
The rain happened to start fairly light, which caused the dry ash covered soil and ash filled roots to begin “wicking” the water downwards increasing its ability to soak it up.
I have 30 years experience in excavation and have worked closely with geologists and have dismantled a number of “nested boulder” structures on slopes so have seen how the roots encircle the bottoms of rocks, and how the rocks are often bearing on one another on a sloping plane.
After the light rains, heavier rains started, and that began soaking in, weakening the cohesive structures of soils holding the rock in place. Then the 1/2 inch in 5 minutes hit, and that was way too much. Slopes that were already failing and falling into the flowlines of gullies had bloked those minor gully systems. The 1/2 inch caused them all to break at once, and any major flowlines that were blocked by the same effect gave way too. This while major slope planes of nested boulders and floaters were also triggered to move.
I had always wondered about the rich black soil when excavating in some areas of Montecito, as well as the masses of huge boulders strewn around.
Clearly, wood framed structures have no place in this environment, and all construction near water ways needs heavy structural shielding from the downstream flowing debris that happens a couple of time a century perhaps.

—Very detailed and thanks for highlighting many sources of info for public. Many top points such as giving contrast of the drainage infrastructure in San Gabriels with the lesser efforts in Montecito area.
—One detail on the 631 Parra Grande mansion having a “red dot” nearby:
Likely referring only to the garden “pavilion” that is right by Montecito Creek. (Assumed named “Montecito” in that area as downstream from where Cold Spring and Hot Springs join.)That “pavilion” or whatever it is called, is two stories but just large enough to have stairs and then an area on the top floor to walk around a little, and look down on Montecito Creek and up the “Persian Gardens” rising to the mansion, which must be 30-40′ higher or more.

Why don’t you just take the Amtrak train from LA?

Hi Doc,
A bit of history here, my husbands family (Neal) owned the property on Olive Mill from Casa Dorinda down to the beach back from 1870 – 1955. Back in the 1870’s there was a historic flood that came down Montecito Creek and wiped out “Old Spanish Town” which was located at East Valley Road & Para Grande, then head down Olive Mill Road destroying many out buildings on the Neal farmland. So this area is not new to flood disaster.
Thanks for the info on your blog……hope you, Joyce & Jeffery are well. I love retirement!

Thank you so much for your detailed report, it is so very helpful and explains so much of what happened here. My big question is with the fore knowledge everyone had, why on earth did they not have a mandatory evacuation for the whole area? The Mandatory evac was for north of the 192, but no flood or mudslide is going to stop north of the 192, what & mud keep flowing down all the way to the ocean, whoever made that decision is liable for all of the lives lost in the voluntary area below the 192……it seems to me the authorities knew enough to make that call.
-
Good history. It’s important to stress that this disaster would never have happened at this particular time if the Thomas Fire had not denuded the hillside.Over 20 inches of rain fell during the Jan/Feb 1969 floods, but there were no significant mudflows the size of the recent one, just a lot of water flowing down the creeks and some debris and a few houses destroyed. No loss of life then either.
-
Thank you for citing John McPhee’s excellent book, The Control of Nature. I keep a copy at my desk. The section “Los Angeles Against The Mountains” should be required reading for anyone thinking of living downslope of the Coastal Ranges, Santa Ynez or the San Gabriels. Of course, 30 years ago I prudently chose to relocate from the L.A. Basin up here to Bakersfield in Kern County, though just as close to the San Andreas Fault.
-
Hi Doc,
I will add a thank you for your report. I will also add to the bit of history that I know of the area, as Sue Burk did. These accounts should be shared and added to our history base.
The current debris flow event is tragic and if more stories of past events in the Santa Barbara area were in the fore-front of current residents thinking, perhaps people would have taken the evacuation notices more to heart.
El Capitan Creek has experienced two significant events within my family’s time in the area. Both were large enough that if El Capitan canyon was populated the same way Montecito’s canyons have developed, a similar loss-of-life tragedy could have occurred.
My grandparents ran the general store and campground at El Capitan State Park when it was still in private ownership. According to the story my grandparents told me, during the spring time of 1956, after the September Refugio Fire of 1955, a large debris flow came down the El Capitan canyon demolishing cabins higher up the canyon, rearranging the stream bed, taking the general store (located by the current day train trestle) off it’s foundation and depositing it downstream along with several feet of debris over the campground (located at that time under the large sycamore trees close to the ocean). I do not think there were any deaths.
A similar event happened in January 2017, as a result of the Sherpa Fire. This time the damage was to the private campground at the base of the canyon above the train trestle. This was described more as a flash flood, but if you were in the path of the water, the damage was still catastrophic. It demolished the cabins, moved cars as far as the beach and stranded multiple campers. Luckily there were no deaths.
My family lived in Mission Canyon (on Foothill Rd) during the Coyote Fire. I was surprised when I read yesterday that homes and bridges were lost when rains came after that fire. Now, at my then-age-of-three, I wasn’t keeping up with current events, but I lived there for many years after that and never knew (or heard stories) about that debris flow.
Knowledge through first-hand stories is a powerful motivating factor for events like this. I now live on a barrier island on the east coast of Florida. This is considered a high risk location for hurricanes. I know what “Evacuation Fatigue” feels like. I also listen to the stories of people who didn’t evacuate, even if it was the third time that season, and the tragic consequences of staying on a low lying island in a Cat 3-4-5 hurricane. I have heard enough stories; I evacuate.
My thoughts, prayers and condolences to all effected by the fire and flow. I hope the history of this tragic event stays at the forefront of resident’s minds and is told over and over again. People living in the canyons and their basins need to know..and listen. Another debris flow, flash flood or mudslide will happen again.
-
Thanks Doc. Maybe if we had better news coverage I would not be as grumpy about the length of road closure. A friend said they took 90 truckloads out in one day and my thought was: why not 900? Seems they need to make it into an assembly line, not one truck backing up to one track-hoe.
Thanks for your great report and response to my questions.
I look forward to the lecture on the 25th. I’m somewhat of an amateur geologist after owning a home in south western Utah for 17 years.

Hwy 58 is a very small, winding, unlit at night, two-lane country road with nowhere to stop for anything.

County Public Works presented the map showing all the possible flooding several days before the rain at a press conference. Trouble was, the mandatory evac map cut off at 192 but the flood map went all the way to the ocean. Hope you can enlarge the map on your screen. They said flooding was expected and “He identified “four critical areas” that are dangerously vulnerable to flash floods and attendant mud and debris: within the burn scar; immediately outside its perimeter; creekside properties; and lowlands with histories of flooding. He encouraged residents to visit countyofsb.org, where they can punch their street address into an interactive map pinpointing homes in dangerous areas. https://www.independent.com/news/2018/jan/05/significant-storm-way-santa-barbara-county-officia/

Here is a better flood/debris flow map and warning from the County on Jan 6th…https://www.edhat.com/news/map-released-of-flood-and-debris-flow-areas

https://www.independent.com/news/2018/jan/12/scrutiny-grows-over-mandatory-vs-voluntary-evacuat/
I sent this to the SB Independent in response to an article that contained the predictable and predicted flow map. Had my friends who lived on East Valley Road (Hwy 192) who were designated in the “voluntary evacuation zone” seen the map which the County already had, they would have evacuated and Josie would be alive today.
The big question is why the powers that be did not publish the actual predicted flow maps!
The mandatory evacuation orders for West Goleta were obviously based on a realistic assessment of topology and burned areas. Montecito obviously was not. Refer to the evacuation order maps published Monday morning. It does not take an “expert” to figure this out. The flow maps now published were predictable and predicted. Lives tragically lost due to sheer incompetence. The courts will decide if this is criminal negligence for the victims in the “voluntary” zones
-
Well, watching news videos of a track-hoe loading a cubic yard at a time into a truck doesn’t look like a recovery effort to me. But maybe that work is in a different area of the flow. I would think they could predict within the flow she was lost in where the body might be and take that section of freeway sludge, remove it and sort through it somewhere else. Cadaver dogs would locate it pretty easily. It is also possible that they will never find her remains.
Yes, we build a home 12 miles west of St. George in the Kayenta subdivision 18 years ago. Just sold the house this year. Incredible scenery and geology, terrible heat in the summer, a nutty place to build any home except in a south facing berm. Lots of photos of it all on my Facebook site.

To Ron Buckley,
According to my daughter in Carpenteria: There is a constant continual line of trucks hauling mud and dumping it onto the beaches in Carp. It is an emergency. Cannot be concerned about all the pollution of mud, ash, fire retardant, et al. The ocean is sweeping it all away!
-
I was so sorry to hear about this, and thank you for explaining it all. Don’t understand all of it though.

Your info was great.
I would like to know WHY the Post Office officials have not been included in any of the public briefings? People have a lot of concerns about the mail delivery. -
Thank you for the informative article.
Note to those that think the clean up efforts aren’t fast enough or there should be more equipment and trucks, it needs to be an organized process. The contractors and government personnel are moving as efficiently as possible. They are working long hours and diligently but if you try and cram too much equipment in one space it will slow down the process. More equipment does not necessarily equal faster clean up especially given the constrained space and lack of haul routes. -
In very recent history locals have seen the horrible mudslide that killed several people in La Conchita, so we do know about mudslides, but that one did not have a burn scar above it. I remember a couple who were swept to their death on Montecito Creek, during a flashflood, not a debris flow, still holding each other. Last year, a debris flow washed cabins in El Capitan Canyon, 20 miles or so, north of Santa Barbara down the canyon after the Sherpa fire burned in the hills above. Here is an exhaustive article on debris flow disasters in SoCal…https://www.newyorker.com/magazine/1988/09/26/los-angeles-against-the-mountains-i

Looks like I just posted the same article by John McPhee in a 1988 New Yorker Magazine posted by Doc Searls in his original post. Sorry for the repeat.

Disaster happen. But can we compare the abatement practices of the 1990’s and perhaps discover ways to reduce the damage.
Time to clear our creeks and reduce the size of the chappetsll -
Thank you for the informative article. My heart goes out to all of the victims families. When I lived in Ventura, I worked a lot of jobs in and around the Santa Barbara, Goleta, UCSB, and Montecito area. On many of the jobs in the foothills of The Santa Ynez range large boulders would have to be removed from the job site in order to construct the foundations, so it does not surprise me that the mud flows contain many boulders. After reading your article and the comments, what is clear about human nature is the “it won’t happen to me” syndrome. Some people do not even read or listen to the news, and would not evacuate if they had. So, blaming the authorities for not making it mandatory when they were guessing at best about where the storm would hit California, seems unreasonable. JMHO. Thanks again!! BTW, my son is one of the many Sheriffs deputies that are working 7 days a week right now to keep the Montecito area safe.

Perhaps the whole concept of emergency evacuation orders needs to be re-evaluated. Instead of issuing blanket “mandatory” and “voluntary” zones as was done for the fire and then the flood, it would be better to first identify the particular type of threat and deal with it in an intelligent manner depending on the need and risk assessment. For example: The fire is a relatively slow moving, observable condition. Equipment and personnel are moved into and fight fires in a warlike, strategic and tactical manner. Affected and surrounding areas need to be evacuated not only for the safety of the residents, but to facilitate the movement of said firefighting assets. A flood zone(s), such as what we have seen in Montecito, was accurately predicted based on a set of factors including unstable burned areas, weather forecasts and especially topology. Some of these are absolutely known like topology, others like weather and hydrology may not. In any case, with our supposed and demonstrated expertise in scientific modeling and almost universal communication, one would expect advisories with a degree of risk/ danger assessments to be provided to the residents based on their location. Gee, they (the authorities) already had such a map worked out days before but for some reason did not send that out instead choosing to demarcate the “voluntary zone” at East Valley Road (192); they even announced “free sandbags” to be available! This really lead a lot of folks and victims to a false sense of “understanding”of the impending danger. East Valley Road was not closed that night. Yes, let’s appreciate the dangerous, effective and great work those on the ground are doing, including sheriffs and others but law enforcement is just that; the higher authorities are to blame for irrational lack of judgement and mismanagement.

Tom – there is no such thing as criminal negligence.
There is either a crime – someone did something bad with intent to do it. Or negligence, which is pure thoughtlessness to do or not do something that other reasonable people would have done or not done.This is such a great article. I never knew. Growing up here and hiking and wondering why rocks were where they are. Now we know. With the Coyote Fire, with that much damage, was there loss of life?
I will never forget my friend Dr Montgomery and I will never let someone say fake news without pushing back. And I will always push friends to listen to evacuation orders and not let “the news always hypes rain” statements get made without arguing. After both La Conchita events and the Sherpa fire mudslide aftermath and now this, I want to learn and share so next time we have this happen, no one gets hurt. Devastating sadness for the families of the victims.
-
Well, somebody or others who knew better and beforehand, and actually had a map describing such, willfully disregarded the impending threat. As taken from a simplistic Wikipedia definition for “criminal negligence”, here is a snapshot for consideration.
The degree of culpability is determined by applying a reasonable person standard. Criminal negligence becomes “gross” when the failure to foresee involves a “wanton disregard for human life” (see the discussion in corporate manslaughter).
The test of any mens rea element is always based on an assessment of whether the accused had foresight of the prohibited consequences and desired to cause those consequences to occur. The three types of test are:
subjective where the court attempts to establish what the accused was actually thinking at the time the actus reus was caused;
objective where the court imputes mens rea elements on the basis that a reasonable person with the same general knowledge and abilities as the accused would have had those elements; or
hybrid, i.e., the test is both subjective and objective.The most culpable mens rea elements will have both foresight and desire on a subjective basis. Negligence arises when, on a subjective test, an accused has not actually foreseen the potentially adverse consequences to the planned actions, and has gone ahead, exposing a particular individual or unknown victim to the risk of suffering injury or loss. The accused is a social danger because he or she has endangered the safety of others in circumstances where the reasonable person would have foreseen the injury and taken preventive measures. Hence, the test is hybrid.

As per the previous comment by Susan Belloni on January 17, 2018 at 10:05 pm: EXACTLY. If these were published by the press for the public before the storm, 1) who developed them? 2) why were these not used to inform the residents, businesses, et al in the “voluntary zones?; 3) who was it the decided to create the 192 demarcation and not even close the 192 that night? 4) why were the residents in the danger zones informed by the authorities like they did to the “mandatory” zones who were not even going to be affected due to topography?

It is interesting to note in the map showing damaged homes that only one home was damaged in Toro Canyon. I lived in Toro Cyn during the 1969 catastrophic flood. It flooded all the way to the ocean and closed the freeway for a time. Obviously the storm cell that caused this flood was small and concentrated on Montecito between Eucalyptus Hill and Sheffield Drive/Romero Canyon. Which means that areas below the burn not under the cell are still laden with debris and subject to what occurred in Montecito. That would include the City of Carpenteria which like Montecito is built on a low lying flood plane. Let’s hope should more heavy rains arrive this winter the people who determine mandatory evacuation maps are not the same ones responsible for this tragedy.
-
I did not see any meaningful mention of the role that Montecito water disctrict broken water mains and 9 milllion gallons of water may have played in making this disaster worse. They are man made hence geologically new. You could potentially say the Skofield is a “dam” break and definitely made that debris flow worse.
-
Tom, they did publish the flood maps, had the flood map at a press conference, developed by County flood control, many agencies participated, people were warned but they apparently decided to stay. You would have to aske those who stayed, why did they stay? They didn’t see any warnings at all or they disbelieved the warnings or what??
Emergency crews were pre-positioned, they saved people who refused to evacuate. Why would you close a road to people who did not heed the mandatory warning and thus trap them there?
Please read this, I thought I posted it already…https://www.noozhawk.com/article/urban_hikers_magnificant_7_recount_intense_day_rescues_in_montecito_floods

The critical issue is the evacuation map and the fact that mandatory evacuation procedures were based on that map which was a fire evacuation map, not flood. Had the in person evacuation message given by sheriff deputies to people living above Hwy 152 been given to those in the flood zone as depicted by the flood map I would guess that a lot of the deaths could have been avoided.
