This home was sinking in the back and you can clearly see the sidewalk sinking and the displacement with the concrete. Additionally, the massive stucco crack you see is more evidence of severe settlement.

This is a property in Sherman Oaks with some serious work needing to be done to the hillside. These old railroad tie retaining walls are slipping due to the soil erosion and the home is settling in their place.

This was a mudslide caused by a water leak in the property above this sidewalk. Luckily the DWP turned off the water but it was a little too late and the slide happened anyway.

The concrete footing from the wall above slid down the hillside and came crashing into the wall below.

the path of destruction.

This is where the footing was compromised and the steel post with concrete surrounding it is the only thing left.

The Wall did a pretty good job of holding back the slide, though it will definitely need to be replaced.

This was an old 1900's home in Echo Park that was very brittle. One of our guys tapped the horizontal crack on the concrete foundation and a huge chunk simply fell off.

The rebar in this foundation had expanded due to high moisture intrusion in the concrete. This causes the concrete to break apart due to the exterior pushing pressure of the steel. Most steel with be effected by this unless treated.

You can see this old retaining wall beginning to fail at the top right of the image. Dangerous.

I don't know where they got this sign, but it fits the situation well as the foundation has been undermined and now the home is sinking on the back side.

Poor little guy.

This was a hillside that was showing signs of collapsing. It was very steep and didn't have much vegetation to hold it up. We are excavating much of the hillside and putting in a pipe and board system to hold back and tier the hillside.

A parking garage about 20yrs old or less in Phoenix had the same moisture in the rebar. Spalling showed the problem. One corner sunk badly!

I wonder how many of these would just be better to demolish and rebuild from scratch? I can't imagine that they can be made 100% sound now.

Can be harder to permit a tear down, even one wall retained from original structure can make it a remodel instead of new construction

with enough steel and glue you can do anything, question is if it's cost effective ;->

I live in Sherman Oaks. The hills are littered with houses built too close to the edge.

I'm sure that's not the only house that is brittle in Echo Park. Some of those houses are super old.

We see more homes in Echo Park/Silver Lake area than probably any other area in LA County. I can totally confirm a lot of them are horrible!

Is that Sherman Oaks home (Deck over railroad tie retaining wall) on a lake? it looks very familiar.

I've had people tell me, when quoting a new policy, there's no existing damage and when the inspector goes out there it look like this. 1/2

Some try to get a new policy to pay for old damage. Hence the NOPE
