They will really only get hit on county taxes which aren’t very high for starters. And oddly the newest stuff might actually be the least impacted. It will be all the little Ryan homes built in the 70’s that are now going for over $300k that will see the big shift.

Their township taxes should be pretty much the same since there haven’t been big shifts in value within the township itself.

The same is probably true for school taxes. Places like Zelienople and Evans City that had more value relatively speaking in 1969 will see some of their school tax burden shift out to the townships. But since the levels of development have been so lopsided, even if Zelie’s share of school taxes got cut in half that would be a pretty small increase absorbed by all the development everywhere else in the district to make up for it.
