The old TransportNI managed car parks in Derry brought in over half-a-million pounds in revenue in the last year of their administration by the department before they were transferred over to Derry City and Strabane District Council as part of the devolution of powers to local government.
The Minister for Infrastructure, Chris Hazzard, provided the revenue figures for the twelve car parks dotted across the city for the year 2014/15.
The car parks brought in £673,123 over the year but this was offset by collective enforcement costs of £109,973.
The Department also said that the figures did not take account of rent, rates and overheads, so the figures released did not represent a simple profit of £563,150 across the car parks.
The top earner was the 176 space Bishop Street car park, which brought in £166,311.
Total enforcement costs for the car park came to £27,833.
A DFI spokesperson said: “Bishop Street therefore earned income of £166,311 in the year to March 31, 2015.
“There were enforcement costs of £27,833 for Bishop Street which means the income net of enforcement costs was £138,478 for Bishop Street.”
The other big earners were the 143 space William Street car park (£116,830 revenue; £14,217 enforcement costs); the 83 space Victoria Market car park (£100,763 revenue; £19,758 costs); and the 85 space Foyle Road car park (£87,296 revenue; £6,922 enforcement costs).
The £673,123 in revenues were brought in through car parking receipts and Penalty Charge Notice (PCN) receipts from illegal parking within the car parks.
And the £109,973 in enforcement costs were incurred by way of Traffic Attendant Costs, Penalty Charge Notice (PCN) Costs, cash collection costs and Park and Display machine maintenance costs, the Department of Infrastructure confirmed.
