Thursday 1/7/2009 – Residents Briefly Return

Thursday 1/7/2009

  • Finally: KGO-TV 7, Residents visit threatened Pacifica apartment. Folks were given a few minutes to retrieve the last of their belongings.
  • Resident report that more dirt fell last night from the bluff on Esplanade, but I don’t have a clear idea of the location. UPDATE: no other confirmation of this… it might have been a delayed reaction from Sunday.
  • Nice clear description of the most ambitious / expensive repair plan in this KPIX CBS5 TV report Engineers Work on Saving Pacifica Cliff. After a slow start, the piece has nice video and archive pictures that show the huge loss of the bluff to erosion.

Did you feel it? Thursday, January 7, 2010 at 10:09:35 Local


Minor shake just now, Thursday, January 7, 2010 at 10:09:35 Local… one of the cats looked around, and I thought at first it was big truck outside, but it was an earthquake. According to the USGS it was magnatude 4.1 just northwest of Milpitas, about 44 miles from here.

The USGS website “Did You Feel It” is an excellent resource for gauging the strength and reach of shakes, as well as reporting your own experience. http://earthquake.usgs.gov/earthquakes/dyfi/

What happens next may depend upon the building

KTVU.com, PACIFICA: Owners Of Cliffside Home May Pay For Guard Against Forces Of Nature [John Fowler] – Video – KTVU San Francisco

According to this KTVU story the emergency repairs that added rock rip rap to base of the bluff are all but done, and it is time for owners of the effected buildings along Esplanade Ave. to decide what sort of permanent fix should be done. Today engineers and the building owners met to review options and prices, and a follow-up meeting to discuss owners’ decision is planned for the beginning of next week. The story quotes an estimated cost for repairs at about $1 million and supposes that the cost might possibly be shared by 4 owners. Aside from some pretty pictures and an ominous mention of high waves this weekend (it’s winter and it’s the Pacific – can you say potential for “Mavericks” surf competition?) that’s about it.

Unfortunately, John Fowler, the correspondent in the piece, did not address the critical difference between the problems faced by the 330 Esplanade owners, and that of the neighboring buildings along the bluff. Mr. Fowler also did not mention a permit application already before the Coastal Commission, but it’s unclear to me whether that will ultimately matter much.

330 Esplanade had been “red tagged” – deemed unsafe for human occupancy – and the rock had only stabilized the building’s structure. According to Pacifica (building inspector? sorry, I’m not sure), people will not be allowed back inside until a permanent fix is in place. The neighboring buildings along the bluff were probably never in danger, though the rock rip rap behind them was built up, too. At this point they don’t seem to need any more attention to weather the rest of the winter.

So the owners of 330 Esplanade urgently need 40 foot horizontal soil nails to reinforce the top of the bluff, stronger wave-level armoring, and possibly a full-height concrete sea wall. All that does sound expensive. Meanwhile the other owners may have no urgent need for work to rescue their property at all. No urgent need, but in fact the other buildings do need additional work done to the bluff.

The building owners are currently waiting for the Coastal Commission to take action on a permit application dating back to late 2008 or early 2009. While I have not seen the application myself it has been reported to include sinking a concrete wall 15 feet below sea level to deflect the velocity of the ocean’s waves, and a concrete-and-steel stitch pier retaining wall sunk into the top of the cliff to hold the bluff together. I understand the owners expect to get the permit approved and planned to get the work done this summer, perhaps starting in June.

Since I don’t know more, and I’m neither a part of the engineering team nor a building owner, I can’t judge how similar or different the urgent work is versus the planned permit before the Coastal Commission. I also don’t know if the existing permit application complicates things for the owners. Also unknown (to me) – can the new work be OK’d as emergency repairs, since that seemingly short-circuits the normal slow / conservative Coastal Commission, and would that allow the pending work to start as well? I think it’s safe to guess that work done on an emergency basis during the winter will cost more than if it’s scheduled and during the summer.

Given the different challenges facing the owners of 330 Esplanade and the other owners on the street, I would not be surprised to hear that they want to take different actions, and spend different amounts of money.

The KTVU story’s conclusion was quite correct, we need to wait to hear what the owners decide.

After the Initial Crisis, Questions about Direction and Cost

As work on the rock rip rap installed and built-up at the base of bluffs behind the apartment buildings on Esplanade Ave in Pacifica wraps up, attention turned to the options, stumbling blocks, and costs of permanent repairs.

Julia Scott of the San Mateo County Times reported this evening on making the buildings safe to be occupied in an excellent article, Owners face costly options for saving imperiled Pacifica apartment complex.

I’ll summarize the highlights that caught my eye and editorialize and extrapolate a bit, but there’s a lot more to Ms. Scott’s fine article and I urge you to read it yourself.

Apparently the near-total loss of the bluff behind 330 Esplanade means that a sea-wall at the beach, the seemingly typical approach to reverse and prevent damage from waves and tide, will not be enough to make the building habitable. Work will have to be done at the top of the cliff to reinforce and hold it. Before any work could start though, plans need to be drafted and then presented to the Coastal Commission for a work permit. In addition to the time required just to get the permit, this approach appears to face several major problems: it’s expensive and the building owner hasn’t approved the cost; it would be necessary to convince Pacifica officials to allow residents to return without the buffer of the wider bluff-top; and, owners of neighboring buildings may be asked to spend their own money to extend the repair along the bluff.

Meanwhile the neighboring buildings do not seem to be facing a similar threat from the collapsing bluff. Even though a noteworthy chunk of cliff dropped away from the south behind 320 Esplanade, engineers did not see it as serious. “Unfortunate,” Tony Fortunato of Engineered Soil Repairs called it, and the property was thoroughly inspected and measured, but the work on the rock rip rap at the base of the bluff was judged to be good enough to protect the building.

Doing nothing beyond the rip rap is not an option for the owners of 330 Esplanade according to Steve O’Connor of Engineered Soil Repairs: “they can’t just leave it unrepaired because it’s going to threaten the neighbors and the road. They do have some responsibility to prevent this from impinging on others.” I’ve seen the cliff behind 330 Esplanade and I agree that doing nothing is not an option, but I’m not sure that the owners of that building are the ones who will step up and do something.

The silence from the owners of 330 Esplanade seems noteworthy to me, though I guess reporters such as Ms. Scott are getting plenty of current information from the company hired to do the work, Engineered Soil Repairs, and a representative, possibly the building manager (I’m not sure), Bart Willoughby. Apparently there are more meetings between the engineers, the owners and the city planned for this week, so perhaps we’ll know more soon.

Beyond engineers and regulations, permits and plans, there is so much that has not been discussed or revealed that I barely know where to start. Why was no rock put at the shore behind 330 Esplanade this summer, when rock was put behind the other buildings? Isn’t “doing nothing” almost certainly a very viable option for the owners of 330 Esplanade? The building is no longer a profitable business, at least for quite some time to come. Couldn’t they just default on a mortgage, walk away, or do something else that would require the property to be foreclosed. Once the property is the bank’s or Pacifica’s hands, wouldn’t they just demolish it and be done with the whole problem? (Maybe that’s too simple because the bluff erosion is already threatening the neighboring buildings, but no one has said that yet.) I understand that several property owners along Esplanade already have an outstanding permit application before the Coastal Commission for the bluff; what is that work for, and what is the status of the application? (I’m not certain but Ms. Scott may already have answered this here.) Finally – where are the lawyers? This is California, isn’t it?

Mavericks Competition Soon & Surf Photos from November 2008

According to a KGO-TV report, the  Mavericks surf contest could happen Monday. According to Mark Sponsler, surfer and developer of the surf forecasting tool Stormsurf.com, “For Mavericks, we need continuous waves that are twenty feet high or more.”

I’ve seen the big surf at the Mavericks break and it is beautiful and overwhelming and awesome; some day I’d like to get out on the photographer’s boat with a 400mm or 500mm tele and get some real photos of it. You can see what I got from Pillar Point in November 2008 on Flickr and below, on this Cooliris Photo Wall.

(Neat thing to do with this wall… click the top left photo and it will zoom to fill the wall. Now tap the down arrow key on your keyboard to see the next picture. If your mouse is over the picture, you can read the text I provided for each image.)

Engineers Make New Plans to Save Crumbling Pacifica Cliff

Tuesday 1/5/2010. KRON 4 report from their 5:30 AM newscast “Engineers Make New Plans to Save Crumbling Pacifica Cliff” (no direct link, just try their home page).

Engineers met Monday to plan conclusion of the rock rip rap and start of emergency bluff stabilization below 330 Esplanade. The neighboring building, 320 Esplanade was inspected and measured, and there were no plans to evacuate it. 330 Esplanade is almost stabilized but there are no plans to allow residents back. Highlights from the video:

  • most work on the rock rip rap is complete
  • no mention of adding 10-ton boulders to the 4-ton rock as was mentioned in their report from yesterday noon
  • engineers measured the bluff around 320
  • no plans to evacuate 320
  • confirms that the next phase will probably include soil nails (long metal rods) and retaining plates for the bluff below 330
  • workers to use the crane to work on the bluff, though drilling and driving the soil nails from a moving basket sounds difficult
  • no word on when the next phase will start, but keeping the crane here must be expensive, so figure it to be ASAP
  • good video showing the loss of bluff behind 320 resulting from Saturday’s fall
  • no mention of any work planned for 320
  • no mention of moving 330 back from the street
  • no mention of allowing residents into 330
  • sad interview of an ex-resident of 330 who wanted to get back into her apartment to get some stuff out of the kitchen
  • no plans for residents to return to 330 yet

April 2009 Coastal Commission Permit Approval for Rip Rap

In a recent Pacifica Riptide article Coastal Commission: Esplanade Bluff and Riprap we get a link to the north central coast district Deputy Director’s report from April 10, 2009. The Deputy Director determined that installation of rock rip rap below 310 – 340 Esplanade did not require a coastal development permit… “because the development is necessary to protect life and public property or to maintain public services.”

As I read through the report (included below, or here Deputy Director’s Report, North Central Coast, April 10, 2009 (F3-4-2009), or go to the Riptide article for a link to the official PDF) these were some of the questions and issues that came to my mind:

  • This decision cleared the way for the work done last summer for 310 through 340. No rock was put down below 330, though.
  • Decision explicitly limits the work to “Phase 1” of an existing larger project applied for under regular calendar permit 2-03-018. (See CONDITIONS OF APPROVAL item #2 below.) I’ve searched all over, in the Coastal Commission website and out, and can’t find permit “2-03-018”. This is unfortunate since we’ve heard various players refer to “Phase 2” without having it defined.

(NOTE: This post is part of my coverage of the cliff erosion and collapse at 330 Esplanade Ave, Pacifica. For a complete chronology and links to many photos see Evacuation underway at 330 Esplanade.)

Here is an excerpt from the Deputy Director’s report:

Collapse behind 320 Esplanade

12:00 Midnight Saturday December 2, 2009. In a report at about 5:00 PM Saturday  Local news KTVU Channel 2 picked up on the substantial new cliff fall I mentioned earlier in the day, and added some useful additional details. The key points were:

  • This took place behind 320 Esplanade, the building next door to the one that had been evacuated.
  • Residents and neighbors were worried but the chief engineer was not overly concerned. “We didn’t want to see it go. We were hoping that it wouldn’t but it did and it’s not really the end of the world at this point…looks worse than it is,” said Tony Fortunato and engineer with Engineered Soil Repairs. Fortunato said, unlike the condemned apartment building, enough cliff-side still remained behind the neighboring building.
  • Nevertheless, it was significant. According to the report, approximately a ten by thirty foot long section of cliff-side collapsed.

See the KTVU report for details: Huge Chunk Of Pacifica Cliff-Side Falls In Ocean.

Pacifica cliff no longer in emergency state (soil nails)

Wednesday December 30, 2009

  • ABC7 KGO-TV Focus of Pacifica cliff repair shifts to second phase. Great story, knits together the end of the emergency phase one repairs and the plans for phase two work to reinforce the top of the cliff.
    • “330 is pretty much completed. Coastal Commission came down and looked at it. We’re going to tune it up a little bit per their requirements,” said engineer Tony Fortunato. The engineers are reviewing several methods for stabilizing the still-eroding top of the cliff. The one they will probably go with is called a “Soil Nailing System.” The City of Pacifica still has to approve the use of a horizontal steel rod system and engineers have to pre-determine precisely what angle to insert them to hold the soil together. If permits are fast-tracked the work could begin in a couple days.
  • SF Examiner, Pacifica cliff no longer in emergency state. According to Tony Fortunato, superintendent at Engineered Soil Repairs Inc., the company hired to put the boulders in place, “The upper bluff is falling as well,” Fortunato said. “We have to fix that somehow.” He said the crews have been considering inserting soil nails, or large metal rods, into the cliff to stabilize it, but said he doesn’t know how long that process would take.
    Perhaps the quote from yesterday’s KGO-TV story was in error when it referred to using metal plates or sheets at the top of the cliff.
