Artificial turf is in the process of being put down at the Dean Street Playground, which is between 6th Avenue and Carlton. The project was supposed to be finished last month, according to a Parks Dept. worker who was on the site last week, and the new target completion date is this Thursday. The Parks employee said the contractor on the job has been having trouble getting the turf to adhere to the playground’s asphalt surface. In addition to the synthetic turf, the ballfield is slated to have new dugouts and spectator benches. GMAP
