AT times when the Rams play at home, there will be just 79 parking spaces at Derby's new Arena, a report has revealed.
This is 21 fewer than the authority believes there would be a demand for.
But Derby City Council says this was not an oversight and that no major events will take place on the site at this time.
It has said that it will be encouraging people to walk or take public transport to the venue.
There would usually be 1,179 spaces available.
Councillor Alison Martin, cabinet member for leisure and culture, said: "The football club has the rights to use the spaces at that time. "But we have a reciprocal relationship with the football club so at other times we can use some of their car parking. "At all times, we are urging people to walk or take public transport. There is a park and ride facility that runs from the city centre."
She said the 79 space rule would apply during games, in the two hours before a match, and in the hour afterwards.
She said: "We won't be holding major events at that time."
Mrs Martin added: "It's not an issue we have been surprised by. It's the kind of compromise you have to make with developments like this."
Of the 1,179 spaces available, 28 would be for blue badge holders.
A travel plan drawn up for the Arena by the council predicts a demand for 100 spaces at any one time when there is not a major event on.
It says: "The site's promoter and TRICS analysis carried as part of the site transport statement shows there to be a demand for 100 spaces to be available for Derby Arena."
