District officials said Tuesday that they have classified seven public playgrounds as having a “high probability of injury” for children playing there and that those areas will be prioritized for improvements as the city begins a $30 million effort to renovate recreation areas.

“They’re in terrible shape,” said Jesus Aguirre, director of the D.C. Department of Parks and Recreation. “When we find things, we try to address them, but it’s really gotten to the point where we need to re-do them completely.”
