Neighborhood Operations Division (NOD), a division of the Department of Public Services (DPS) is responsible for maintaining a large portion of visible city-owned property.  Using the city's Greenspace Maintenance Plan, NOD cleans and maintains city green spaces, areas in the right-of-way (ROW), steps, public fences, bridge underpasses, guardrail buffers, alleys, walls, concrete islands and lots owned by or in the care of DPS (includes mowing, weed spraying, and litter pick-up).  Grass cutting occurs April through November: the Department provides a schedule listing the tentative dates for cleaning neighborhoods' green spaces and other related neighborhood cleanup projects.

While the Greenspace Maintenance Plan covers work that the City does to proactively maintain clean neighborhoods,  DPS also responds to citizen service requests (CSRs) for litter, tall grass/weeds, and dumping on both public and private property (for more information on private property cleaning, see Private Lot Abatement Program).  The above visualization shows all green space cleaning/abatement activity in response to CSRs.
