@jk when I was visiting Hong Kong I was puzzled to see "slope registration" plaques absolutely everywhere
I wrote it off as a bizarre bureaucratic quirk, but after I left I went to look up what it was for
apparently the city was ravaged by deadly landsides until at one point in the 1970s they just decided they had enough and that landslide deaths were preventable, so they established a well-funded geoengineering office that catalogued and reinforced every slope on the entire island
they just straight up said "no one has to die from this" and made it happen, and it works; the last landslide death was in 2008
it seems like such a simple thing but I admit I was awestruck by what they did
@technomancy a family member worked on this project! 💙 i didn't really understand the descriptions at all, but it was extremely cool work. visited HK several years ago and as we went around the city on the bus it was a lot of "yeah i needed to shotcrete that slope... and that one ... that one's actually stable as-is even though it looks bad ... we had an argument over the work here ..." etc
felt like they rebuilt half the mountain
