Why build a substation higher than surrounding ground?

This may seem like a very odd question, but yet again the recent floods have highlighted how locating substations on lower level ground can mean that they become flooded, with the high likelihood of the switchgear tripping or, even worse, being damaged. So there you are in your house, which isn’t flooded, but without power because the substation itself is flooded. It’s not always possible to avoid all flooding events, but by locating substations on higher ground you can significantly reduce the chance of flooding.
