You can thank a lack of maintenance on some of these rinks for that.
I didn't say close them all down but...the City better be prepared to put money into them or sell them to groups who would be willing to upgrade or maintain them.
Is there a way to make it safe for someone who is blind/issues with seeing safe to cross? That may be why the bells go off.
I guess if there are pedestrian crossing arms that would be a deterrent too.
