Looks like a bridge from arial photos, but not clear. Should be verified.

These two buildings appear to be missing from Bing imagery. Someone in the area should verify if they exist in reality or not.

The parking space has been extended down further in this direction. Will need survey (or updated imagery)

The houses in this area are highly offset and have incorrect sizes compared to aerial imagery. And not consistently between houses next to each other. Someone should go through and a) find the right imagery offset and b) move the houses.

There seems to be some major issues with unclosed multipolygons here. I tried fixing part of it, but I can't figure out what is going on well enough to fix it properly

Self intersecting way, I don't even know what it is trying to do. Do we even have tagging for waterslides by the way?

This building does not seem to exist in imagery?
