Derek Wright was concerned that the Ladyboys tent went beyond the hard surfaces.
Brighton and Hove City Council said that work was under way to return the areas to their original state.
The council said: “We have a contractor booked for later this week to do basic remedial works and reinstatement on the areas that were occupied by the Ladyboys, the Warren and the Spiegeltent.
“All works are being paid for by the event organisers.
“We are also working on a longer-term plan for bringing this area back to its previous condition, which will start in the coming weeks.”
Work on the final phase of the project to transform part of the city centre is supposed to begin this year.
