Maybe I’m an idiot but how does “mm per year” classify you as being at a high risk of sinking? Seems a lot different depending on your elevation. The highest peak could sink a meter per year and still not be at risk of flooding
True, for not being at risk from flooding from the ocean given elevation (from sea level).
Local flooding: entirely possible. For example, over a few years city X sinks by a cm, because of that in a flood situation there's slightly more flood water. Over a large area that might be quality a few acre-feet of water: that's quite a lot more water.
It's less that the likely hood of a flood increases and more that the severity of a flood increases.
I suspect the Houston number is actually Katy or the gre at Houston area as a whole because last I check Houston-proper has taken some action to reduce the pumping of ground water and mostly stabilized? But the surrounding suburbs think not wanting flooding is commi BS probably.

the circle is the city location, not the tip of the cone, for anyone else who was confused

How much is that in milli-school buses?
nocturne@slrpnk.net · 2 pts · 195d
If we use a bus at 45' and convert that into milli-school bus you get 0.045 feet = 1 milli-school bus. 1 milli-school bus = 13.761mm.
1 mm = 0.00328084 milli-school bus
