Did not respond when scanned

The site did not respond when it was scanned (page.goto: net::ERR_CONNECTION_TIMED_OUT at https://diamondbarca.gov/ Call log: [2m - navigating t). That is not a pass and not a failure — nothing was measured.

What this does not show

Homepage only. One page was tested. This site may pass its homepage and fail everywhere behind it.
Automated only. Automated testing catches roughly a third of real accessibility problems. It cannot judge whether alt text is meaningful, whether a form works with a screen reader, or whether a keyboard user can escape a menu. Passing every automated check is not compliance.
This is a floor, not a verdict, and not a legal opinion.
