And since the school is in the middle of a residential neighborhood, there’s not really any other use of the sidewalks either…
As a European, this statement sounds completely insane. I honestly can not comprehend how a nation got to the point of saying "we don't need to be able to walk somewhere from our house so lets not bother building sidewalks".
You and your daughter should cycle to school though. If she's not old enough to go on her own bike, take her with a trailer bike. If she's too young for that then a child seat, and when she's old enough she can cycle on her own.
The idea of using a car to go 900m is just crazy to us.
