While looking online to confirm there is no street sweeping today I found this site, and since I've never seen it here before I thought I'd share:

http://www.cityofjerseycity.com/today.aspx

This is what is has:
City Hall Hours Closed - Election Day
Special Events No special events scheduled
Meetings No meetings scheduled
Taxes Due No taxes due at this time
Trash Pickup Normal Schedule
Street Sweeping No Street Sweeping - Election Day
Street Closings No street closings

Good to bookmark for a quick look at trash/Street cleaning.

The only thing I wish is that it had the actual date on the page.
I can imagine an instance where they don't update it one day and someone gets a ticket.
