I was speaking of construction of highways that could survive lava flows with no harm.
Once lava encountered the gentle curve of the elevated roadway, it would be diverted to a causeway built using cement piers.
Alternate if the County has such a bug about defending thousands of homes in favor of "nobody" it could be a causeway the whole way.
The causeways in Southern Florida Keys were not built using the money of a few people living in Key West. Instead they were built by people with vision and determination. It is true Key West in turn became a tourist mecca as a result when they could simply jump in a car and drive there.
Certainly some people back when Key West was isolated highly objected. Becoming less-isolated was forced upon them. Here the situation is reversed. Becoming more isolated is forced upon everyone and some think that is a good thing too.
This isn't the diversion thread so back to topic.
Post and pier for homes is the obvious way to go. Several homes in Kapoho are already lava ready since they were built on cement piers. I financed one of them.
Bob2 is the name I gave to a different home in Kapoho that is also lava ready. I own Bob1. Bobs are works of art and engineering by someone named Bob. Bob2 is also known as the Great Wall of Kapoho. A large amount of fill was brought in to elevate the home above local grade and retained with lava rock walls.
The problem with Bob constructions is adjusting after a lava flow is not as easy as pouring higher cement posts.
Cement is not the only building material that need be used. Many metals and alloys melt at higher temperatures than lava.
The underside of the building should have a simple heat shield of galvanized metal if the beams above are wooden.
About how much? Simple cement piers can be fabricated and brought to site and erected with a crane.
Cost over conventional post and pier... perhaps $4-$7k for a typical home.
Cost over slab one grade, perhaps about $10-25k.
Retrofit prices higher.
