Progress Report
November 8, 2009
Landslide Repair Foundation is pleased to report
that the emerging hillside looks very neat – tidy, as we see Phases
I and II completed. But if one could see a hundred feet into the
ground one would be absolutely amazed at the amount, substance and
quality of the work that has gone on.
Phase III.
The 31 shear pins that make up Phase III have been drilled, the
reinforcing cages set, and the concrete poured. This phase is now
ready for the construction of its tie beam. The greatest challenge
in this Phase has been the limited space within which to work,
because of the steep hillside and the relative nearness of the
residences below. Work has progressed rapidly.
The tops of the poured shear pins can be seen in
the attached photo. At the lower left one sees a blue panel. Just
above and to the left of that panel one sees the orderly layout of
the shear pin array for the Phase III wall, as it stretches toward a
palm tree and beyond and awaits the installation of the tie beam,
next up. Tie-backs have already been installed.
Phase VI.
We are also working on Phase VI. A map depicting the relationships
between the phases is attached. A chart depicting the relationships
between the phases is seen below.
There are 39 shear pins in the first (upper) row,
and 40 in the lower. The shear pins will be connected by a tie beam
and up to 6 rows of tiebacks securing the shear pin-tie beam layout.
A chart depicting the relationships between the phases is seen
below."
Here is Condon-Johnson’s update for Phase VI, Wall
1 as of November 3, 2009:
"Two shear pins remain to be installed. We anticipate
completing them on November 4, 2009. The grade beam rebar
install commenced prior and is completed to approx 40% of the
length and continues to be installed. We will form and pour the
beam in three sections. The first section is scheduled to pour
this Thursday, November 5, 2009 (Friday at the latest). A
similar section will be poured the following Wednesday, November
11, 2009, or Thursday. The last section will follow 4 or 5 days
later November 16-17. Tie backs are scheduled to begin at the
first section Wednesday/Thursday, November 11, 2009."
Landslide Repair Foundation is very excited about
this progress. See the map that follows. The location of the two
walls of Phase VI is indicated in brown.
See the photo below, taken on or about
October 30, from across Sycamore Canyon on Las Alturas Road. The
crane being used to drill for the shear pins (white, located just to
the right of center) is positioned to begin work on what is
approximately shear pin #22-24, working left to right, of the 39
shear pins involved in this first wall. Wall #2 of Phase VI, will be
similarly constructed and will have 40 shear pins.
See
also, however, the completed work at the Halstead and Sneddon
properties located upper center. These residences are being
re-landscaped, with a view toward protection from the rains that
will inevitably come.
Just to the right and above the crane on the slope,
is where the site office is now located (on what was the former
building pad for the McKenna property, the house having been
destroyed by the original slide.).
Particular attention invited to how the keystone
wall outlines Canon View Road, and to the keystone retaining walls
above on the Halstead property; a view that is a vast aesthetic
improvement over the pre-landslide layout. See also the photos in
the progress report on the website.
 Phase IV and V.
Phases IV and V were deferred in favor of Phase VI, which is now
under construction. These phases are still in development, and will
address issues at the lower elevation of the slide area. We expect
to see completed planning around mid-to-late December, 2009.
Phase VII.
Our effort to date has pretty much by-passed planning for Phase
VII. Phase VII is generally a clean-up phase where we will address
issues of landscaping, road maintenance and repair, sewer, and
demobilization.
With regard to landscaping, we will be striving for
plantings that are generally native, or are generally accepted
plantings in our area and otherwise enhance the aesthetic appearance
of the work area. We would like to see a native hillside, but one
that is not cluttered by overgrowth and weeds and is not a transient
hotel or home for bedding coyotes. How it stands up over time will
depend entirely on what maintenance plan is set in place and who is
responsible for such maintenance.
Landslide Repair Foundation has not, as of this
time, retained a consulting arborist, and probably will not for some
months to come. We have no idea whatsoever about what may become of
the McKenna property; that will be up to the owner after we are
finished. Also, the sewer and paving issues may drive our budget. We
can only wait and hope in that regard.
How the LRF properties (formerly Loberg and Peyton)
will be used has never really been addressed by the board of
directors or others. Those properties will probably not be developed
for many years to come, if ever, because of the subterranean
improvements that have been installed and/or the need for City or
County permitting.
Eventually, "as-built" drawings will be available
to any inquiring party as they will be recorded in City/County
records.
