Key takeaway: we need to be able to change crossings in bulk from open to warning.
The minimum requirement is to be able to set an entire community to warning/open. This is uesful when we're in a time crunch to update.
Example: The seven Spicewood springs crossings changed to closed around five or six times a year. They all change to closed at/around the same time.
We talked about setting up a relationship between crossings. If you change one crossing to warning, all the other crossings related to it (e.g. downstream crossings) will also change to warning.
The problem with this is that it could be very time consuming to set up.
Would be cool to be able to draw a polygon around a bunch of crossings and update their status all at once.
Some other ideas
Allow communities to show a warning banner.
Allow admins to draw a orange polygon around a warning area. This doesn't affect the crossing status. It just lets users know that there is something going on in the warning area.
