"The failure of this unpermitted hillside retaining wall was triggered by the collapse of a tree in this location, which undermined the surrounding area. The remnants of the roots provide clear evidence of the tree's considerable size and its impact on the landscape.
Although the retaining wall was unpermitted and clearly not built to last, this picture shows us how plants and trees help stabilize hillsides by anchoring soil with their root systems, absorbing water to prevent saturation."
-do not build on hillsides
-avoid post and pier houses
Thanks for giving me good decision making tools i need for the imaginary house i will never be able to buy , on the quaint hillside i will never see:)
- Architects hit me up - i now have good tips for you :)
In ancient times Portuguese Bend was an island, but is now a peninsula due to slides. It is the worst place to build, made worse because of road construction 75 years ago.
Other places where they assess structural damage has clay soil which will expand and contract differently depending on the moisture. This can lead to a drop, leading to the posts not making contact and providing support.
Much of the area is rather terrible to build on, but it is California, and land prices are high.
Three years after closing, it was condemned.
