PHILADELPHIA (WPVI) --A City Council hearing called into question whether the PPA is short-changing the Philadelphia School District.
A portion of money from parking meters and red light camera tickets is supposed to provide money for schools.
Those two revenue streams typically generate more than $100,000 a year.
But some council members are trying to figure out why PPA payments to the school district are going down, even after the parking-rate hike.
The state-controlled PPA says those formulas are set by law.
