Weekend Update


Deeply Undercut Rear of 320 Esplanade

Deeply Undercut Rear of 320 Esplanade


Monday March 1, 2010 – Weekend Update

  • Continued erosion at the open space (“dog park”) but no word if it has increased the risk to building 112 of the Lands End complex
  • No work on Esplanade or at Lands End this past week
  • Work continued on the project to protect the Dollar Radio buildings. This work has been termed “temporary” and expected to provide a year or so of protection only.
  • Fence installed around 330 Esplanade.
  • There are so many posts regarding the erosion-related problems in Pacifica that it’s getting harder to find things. The search functionality on the side of each page helps, as does the Esplanade page. I’ve been tinkering around with a more visual representation of the posts here: Experimental Esplanade Timeline – Version 1. Let me know what you think.

US Army Corp of Engineers, Continuing Authorities Program, Section 103

During the Study Session hosted by the Pacifica City Council on February 10th, one of the possible funding sources that was discussed was an Army Corp of Engineers program called “Section 103”. You can see Section 103 for yourself here, or hit the More link below for the full text.

After passing a pre-selection assessment, a municipality can request a feasibility study. The first $100K of the study is fully Federally funded, but all work after that is paid in a cost sharing arrangement with the local municipality responsible for 35% to 50% of the total, and a cap of $3 million.

The sense at the Study Session was that no solution that might require funds from Pacifica could be considered. It is possible that the Army Corp of Engineers could start a study with no promise of actually doing the work, as was reported in the Feb. 18 Pacifica Tribune story on MercuryNews.com Cliff issues explored in city study session; Agencies offer assistance explaining procedures and permits. This seemed unworkable at the Study Session, though I suppose nothing was ultimately ruled out.

The full text of Section 103, surprisingly readable, follows:

Weekend Update – February 22, 2010

Monday February 22, 2010 – Weekend Update

  • City Council Meeting Agenda items:
    • Adopt Proclamation Confirming Existence of a Local Emergency (Proposed action: adopt proclamation confirming existence of local emergency). For more information see my post Pacifica Declares Local State Of Emergency.
    • Adoption of Resolution Initiating Historic Landmark Designation Process for the Dollaradio Station, 100 Palmetto Avenue (Assessor Parcel Number 009-401-060) (Proposed action: move that the City Council adopt the resolution next in order initiating the historic landmark designation process for the Dollaradio Station). The Dollar Radio (Dollaradio) property on Palmetto Ave. does have an interesting history, see my post Sampling Dollar Radio’s History.
    • Both of these actions seem to be intended to make it easier for property owners to obtain funding outside of the municipal government or local agencies.
  • During the Study Session hosted by the Pacifica City Council on February 10th, one of the possible funding sources that was discussed was an Army Corp of Engineers program called “Section 103?. The main drawback of the Section 103 program seemed to be that even though an initial project analysis could be funded with federal monies, 35% to 50% of the overall expense would have to be paid by Pacifica or a local agency. The consensus at the Study Session seemed to be that requirement for local funding was a non-starter. You can see Section 103 at my post US Army Corp of Engineers, Continuing Authorities Program, Section 103.
  • Work behind 330 Esplanade stopped Monday or Tuesday 2/15 or 2/16, and the crane required to do the work was removed. Some people may be happy for the peace and quiet, but the very real problems faced by the remaining residents and landlords are just waiting to get worse.

Sampling Dollar Radio’s History

One of the properties threatened by this winter’s bluff erosion event is the historic site of Mussel Rock, 6XBB / KTK: Dollar Radio (Dollaradio), an early radio communication site with many notable “firsts” in communications with ships in the Pacific. Long time owner Joan Levin is urgently seeking financial help for her historic home. Dollar Radio is located just north of the Pacific View Villas condo complex on Palmetto Ave. How historic is Dollar Radio?

Dollar Radio played a meaningful role in a number of historic events. Here is some information about just three of them.

  • Admiral Byrd South Pole Expedition
  • Electronic warfare with the Japanese before Pearl Harbor
  • Submarine Attack

Admiral Byrd South Pole Expedition

The three radio towers at Little America, 1929, Richard E. Byrd Papers, #7801_15.

From the Maritime Radio Historical Society, The Robert Dollar Story, Part 1 – By Edward Prather:

Admiral Richard E. Byrd took H & K equipment on his expedition to the South Pole in 1929. After he reached Little America, and set up his radio station 30 feet below the snow, he began communication with the Dollaradio station at Mussel Rock. Night after night the operator on duty would copy material from Admiral Byrd for relay to the New York Times for publication in the morning newspaper.

BYRD ANTARTIC PLANE

Electronic warfare with the Japanese before Pearl Harbor

The Dollar Radio site operated as station KTK before World War II, and one occasion deliberately interfered with a Japanese transmission.

Communication Intelligence Summary, 21 October, 1941 

General. — Traffic volume returned to about normal today. There was no
dummy messages in the TOKYO broadcast. Last night this TOKYO to Fleet
Circuit was interfered with by station KTK (Mussel Rock, California, Globe
Wireless). This interference also bothered the Japanese for TOKYO shifted
his frequency down 10 Kcs. to avoid it.

Source: Pearl Harbor attack : hearings before the Joint Committee on the investigation of the Pearl Harbor attack, Congress of the United States, Seventy-ninth Congress, first session, pursuant to S. Con. Res. 27, 79th Congress, a concurrent resolution authorizing an investigation of the attack on Pearl Harbor on December 7, 1941, and events and circumstances relating thereto .. (1946). Archive.org link.

Submarine Attack

Japanese RO-33 submarine. Date unknown, but before 1942. Source N. Polmar, D. Carpenter. Submarines of the Imperial Japanese Navy 1904—1945. — Conway Maritime Press, 1986

FROM: Radio Spies, Bart Lee, 2002, 2006, page 76:

On December 7, 1941, the radiomen at KFS heard, on 500 khz, the signal for submarine spotted (SSSS SSSS SSSS) then an S O S, then silence. Globe Wireless operators at KTK, at nearby Mussel Rock in Pacifica, also took the traffic. The ether thus carried some of the first signals of America’s Pacific war.

Pacifica Declares Local State Of Emergency

City manager Stephen Rhodes declared a state of emergency Wednesday to help building owners affected by cliff erosion seek low-interest loans to cover expensive bluff repair work. Pacifica City Councilwoman Mary Ann Nihart explained the decision:

We’re not in a position right now where our streets or utilities are going to be immediately at risk, but we wanted to help the property owners as much as possible.

The city’s proclamation covers an the area from Manor Drive to Muscle Rock on Palmetto Ave., and must be approved at various governmental levels up to and including the Governor. If approved, it would allow: owners to apply for low-interest Small Business Administration loans; and, additional work to be undertaken immediately without the Coastal Commission’s approval.

The Federal Emergency Management Agency has repeatedly denied the Esplanade area’s elibility for aide due to the threat being to only private property, and to long-standing pre-existing conditions.

Two More Property Owners Take Action

According to today’s KGO-TV 7 (ABC) story Crumbling cliff in Pacifica prompts new precautions, two more owners are taking action to delay or stop the erosion that threatens their properties along the bluffs in Pacifica.

  • Lands End is reported to have received a permit to build a rock rip rap wall at the base of the bluff below their property. (Story does not say but I presume it was an emergency permit granted by the Coastal Commission.)
  • Work is also reported to be starting at Joan Levin’s home, north of Esplanade on Palmetto Ave near Muscle Rock. According to the story crews are drilling 23, 50 feet deep holes and planting in reinforcing steel and concrete columns. I’m not sure why this owner is NOT having a rock rip rap wall built below her propery. Tony Fortunato described the work:

To buy her time, it’s not a total fix, what it is buying her time. Hopefully in a couple of years they can make a decision. She has a lot of property here, she can move back. They are talking about moving to a house down the road possibly – something like that.

Meanwhile I have heard that the owner of 310 & 320 Esplanade will have bluff reinforcement work begin on his properties shortly.

No word on the status of the Pacific View Villas condo complex on Palmetto Ave.

More on Dollar Radio (Dollaradio)

Joan Levin owns a historic home just north of Pacific View Villas condo complex on Palmetto Ave. The property was once site of Mussel Rock, 6XBB: Dollar Radio (Dollaradio), an early radio communication site with many notable “firsts” in communications with ships in the Pacific. The original tiny 20 feet square wooden structures were replaced with red brick buildings in about 1930. The two 225+ foot tall towers were demolished in the 40’s, but one brick building lives on as part of the residence.

Joan Levin has established (or is still working to establish) a non-profit foundation to underwrite the rescue of the Doallardio property. More information:

No further damage to Pacifica cliffs


Photo credit: http://www.flickr.com/photos/kristiewells/ / CC BY-NC-SA 2.0

The high surf was the headline this weekend. Also this weekend workers took a well-deserved rest and there’s word that work will begin behind 320 Esplanade and Lands End may receive a permit to begin work soon. There has no news regarding the properties north of Lands End along Palmetto Avenue.

High Surf

The Mavericks Surf competition saw waves over 40 feet tall, but at Esplanade, away from the uniquely ramped sea-floor topology at the break, the waves were a much more manageable 18 to 20 feet. Even combined with high tide, the waves washed harmlessly at the 30+ foot tall rock rip rap revetment at the base of the Esplanade bluffs.

Current and Future Work Along Esplanade

Referring to the buildings and the work of the team he is overseeing, Tony Fortunato said

They held up well. We have most of the flashing in under the cliff, now, but not the finishing coat.

Fortunato expects to begin similar work beneath the apartments of 320 Esplanade in the near future.

They’re at the point where the other apartments were when they needed work.

Lands End

According to the KGO-TV 7 (ABC) story No further damage to Pacifica cliffs (2/15/2010) the owners of Lands End are close to receiving a permit from the California Coastal Commission for work beneath their crumbling cliffs, as well. At this point I do not know what would cause any delay, since the Coastal Commission has seemed to turn around emergency permit applications quickly.

Note that the text on the KGO-TV web page is current as of February 15th, but the video is old and dates back to January 25th.

Mavericks IS ON for Saturday, February 13th

The Maverick’s Surf contest is ON for Saturday, February 13th. See MavericsSurf for details and live streams. The first heats are scheduled from 8:00 AM on.

Why We Care

Here’s the Surf Height Forecast from StormSurf.com. Note the peak of 30′ on Saturday February 13th:

The impact along Esplanade Ave could be significant:

    6.2 feet : height of high tide
  +  30 feet : forecast wave maximum height on Feb 13
  ==========
   36.2 feet : combined height of seas plus tide

OK, how about that rip rap rock piled along the base of 320 and 330 Esplanade?

     31 feet : height of rip rap rock along the base of 320 and 330 Esplanade Ave

You can do the last bit of math for yourself, I'm sure!

Our hopes and best wishes go out to the folks who still live and own property in harm’s way. We’ve moved a little bit inland, though still in the neighborhood.
