Monthly parking permit rates will increase $10 in the city next year.

The parking authority Wednesday night voted to increase rates for most of its parking spaces to $60 per month from $50.

The hike will help cover costs associated with the Centre City parking garage and make up for the future loss of rent from the county’s Adult Probation Center in the tier garage on Cunningham Street.

“The probation office is the big loss,” said authority treasurer Jeff Smith. “We get about $7,000 per month from that.”

The office is moving to the new county office building.

The authority manages the surface lots and the tier garage in the city. Its monthly permits range from $30 to $50. All monthly permits will increase by $10 on Jan. 1.

The authority issues more than 450 permits per month. The hike will raise about $45,000 in revenue a year.

The last rate hike was in 2010.

The authority had previously said it expected to raise parking rates by $5 to $10 per month at all of its lots to help pay for the city’s new parking garage.

The authority had originally agreed to contribute $500,000 to the garage, which will join a proposed Marriott Springhill Suites hotel in the Centre City project.

However, that figure has since increased due to restrictions on some of the authority’s available funds.

The authority expected to use about $330,000 it had in different BNY Mellon Bank accounts for its contribution, but later learned $220,000 of that money can only be used to pay off existing debt.

That debt — about $1.8 million — has already been refinanced into the city’s bond issue that will pay for the garage.
