Department of Parks and Recreation. 

This piece of underutilized parkland is surrounded by a fenced off ballfield, highways (Bronx River Parkway, and a Verizon building.  Bronx River Ave terminates here with a good portion of the street sloped towards this location.  Department of Sanitation has put up no dumping signs indicating previous loitering (and/or the washing of garbage from the street).  A great opportunity exists to turn this location into a rain garden/bioswale and create a pleasing entrance to this currently neglected piece of parkland.
