In 2016, the park district approved plans to construct 300 new parking spaces near the main entrance. However, residents filed suit against the parking expansion on environmental grounds, after petitioning to restrict parking on public streets. The same law firm filed the 2016 action which closed the Regional Park at Vargas Plateau for nearly a year. The lawsuit, principally aimed at keeping park visitors out of the local residential neighborhood, was settled in late 2018. The settlement removed legal obstacles that had stood in the way of the expansion, which was originally estimated to cost $6.5 million in 2016. The park district had raised about $1.5 million for the parking lot as of 2018.
