I places in Asia that have monsoon weather one typically walks UP a few steps before going down into a subway station (China/Taiwan/Hong Kong/etc)- for example this MTR entrance in Hong Kong:

This is a great solution to short term small floods, but wont protect you against longer term, or waist deep+ street flooding like we saw in Henan last week.

I’ve lived in Hong Kong for close to 10 years, and I never even thought about why almost every MTR entrance has a couple of steps up, only to go back down.

I thought the walls were the major variable and relatedly how well the earth blocks water in addition to well the local presence. The cost of any street opening subway is needing some pumping as even if you have over-awnings gravity brings rainwater down and it is rare that a city large enough a subway makes sense is away from bodies of water.
