The link to the report is here:
It's a great find as it shows how the council uses parking permits, pay and display as a significant source of revenue:
Parking permits made them £3.6m last year
Pay and display another £3.7m
Penalty Charge Notices a whopping £6.2m
No wonder they love CPZs and the meters and charges that go with them.
As you point out in total they made a £6.1m surplus last year from parking charges of which £5.8m was spent on road maintenance. I would love to know what is included in road maintenance as that has risen from £1.7m in 2011/2012 to the £5.8m figure - yet there are no more roads than in 2011!!!
