[narrator] Nearly a year
after the collapse, work began on a new
retaining wall, downhill of the original. This time, more
than just gravity would hold it in place. [Jack] The original wall
is still here. And that provides
some additional support. But an additional
wall was built, and that wall
consists of pilings
that are drilled down, very deep, with sections
between the pilings

[narrator] Nearly a year after the collapse,

00:00:03.366 --> 00:00:05.005

work began on a new retaining wall,

00:00:05.566 --> 00:00:07.004

downhill of the original.

00:00:07.004 --> 00:00:09.667

This time, more than just gravity

00:00:09.667 --> 00:00:11.001

would hold it in place.

00:00:12.566 --> 00:00:14.003

[Jack] The original wall is still here.

00:00:14.366 --> 00:00:16.005

And that provides some additional support.

00:00:16.566 --> 00:00:19.167

But an additional wall was built,

00:00:19.167 --> 00:00:23.267

and that wall consists of pilings that are drilled down,

00:00:23.267 --> 00:00:26.466

very deep, with sections between the pilings.
