On Richmond’s website, Juneteenth is listed as one of several holidays when the city doesn’t enforce parking time limits. Because of a mishap last Thursday, the city’s parking enforcement contractor ticketed nearly two dozen cars and had two towed despite the holiday.

The city recognized the mistake early in the morning and halted the enforcement, but not before enforcement contractor SP Plus Corp. issued 22 tickets.

“They have since been voided,” said city spokesman Michael Hinkle.

Hinkle said none of the 22 tickets in question have been paid yet, and anyone going to pay them online should see that they have no outstanding tickets. Vehicle owners the city has mailing addresses for should also receive a letter notifying them the ticket was in error and doesn’t need to be paid.

For the two vehicles that were erroneously towed, Hinkle said one owner was reimbursed and the other had their vehicle returned to them without paying a fee.

The city website lists 17 official holidays when parking enforcement is either suspended entirely or limited to towing vehicles in areas where parking is prohibited during the morning and afternoon rush hours.

Juneteenth — a relatively new federal holiday that commemorates the end of slavery — is listed as a full parking enforcement holiday.

It wasn’t fully clear why ticketing occurred. The city spokesman said the parking contractor receives a list of annual enforcement holidays as well as reminders for each day.

SP Plus Corp. didn’t immediately respond to a request for comment.

According to data provided by the city, about $460,000 in tickets are issued each month in Richmond.
