Christoph, Thank you for the observation.
Specific to "roads now intersect buildings indicating that mapping is inaccurate - like here:" They are mostly unreviewed TIGER import, I also saw one instance where we have building but no roads. This was already discussed by the import team and will be fixed during the cleanup/validation stage. Keep your comments and suggestions coming! Will ticket each one and fix whatever we can. Thanks!
