Parking rates at meters throughout the city have increased 25 cents an hour in most neighborhoods up to one dollar more per hour Downtown.

Rates have doubled to $1 an hour for motorists parking at on-street meters in Shadyside, South Side, the North Shore, the Strip District and parts of Oakland. Other parts of Oakland have experienced a rise from 50 cents to $1.50 while Downtown on-street meters have increased from $2 an hour to $3 per hour.

Metered on-street parking in all other city neighborhoods increased from 50 cents to 75 cents on June 1. Parking rates in the Pittsburgh Parking Authority's 36 off-street metered lots remain unchanged.

In addition, in some of the neighborhoods parking enforcement has been extended from 8 a.m. to 10 p.m., Monday through Saturday. Previously, the hours of enforcement concluded at 6 p.m. The affected neighborhoods include: Downtown, Oakland, Shadyside, Squirrel Hill, South Side, the North Shore and the Strip District.

Lengthening the enforcement period applies to nearly 4,900 of the city's approximately 6,800 on-street metered spaces noted David Onorato, the parking authority's executive director.

"The change will require us to stagger the on-duty hours of our full-time officers and supplement their work by adding part-time employees to accommodate the increased hours of coverage," Mr. Onorato said.
