Our town has only one high school and one middle school. There are two elementary schools, one on the “good side” of town and one on the “bad side”. There is multi-unit housing, public housing and a trailer park on the bad side and an identical house would sell for $50k-$100k less if it is on the wrong side of the catchment line. Conversely, when a 50 unit townhome development was built on the “bad side” of town, there was intense lobbying to determine which cul-de-sac(s) would be moved from the good side to the bad side. The cul-de-sac with McMansions won, with the buses for the “good” school now driving past several neighborhoods in the “bad” side to get to that cul-de-sac. Who knows what favors were exchanged.
Oh yeah, the “bad” elementary school has much better test scores than the “good” one. That’s the side of town from which kids aspire go to Harvard, Yale and MIT rather than Bowdoin, Skidmore and Colgate.
