New York City Department of Sanitation: 311 Complaint Spatial Analysis Assessment

New York City Department of Sanitation: 311 Complaint Spatial Analysis Assessment
Author(s): Sarah Williams, Nick Klein
Published on: November 1, 2007
New York City rolled out it’s 311 call system in 2003 and according to its web site it “is New York City’s phone number for government information and non-emergency services.” That means if New York citizens have a complaint, instead of calling 911 – they call 311. Calls requiring service are logged by location and time. People call about everything from dead birds and potholes to juvenile loitering and noise control. The 311 system has increased citizen knowledge about the ability to complain about municipal services, and therefore, has raised the numbers of complaints logged into their systems. This increase in data has captured the attention of municipal managers through-out the city. Among the complaints that are logged, New Yorkers use the 311 call system to report missed trash collection to New York City’s Department of Sanitation (DSNY). Incorporation in the 311 program provides DSNY with the ability to create new statistical analysis techniques on their complaint data. Like all 311 calls, complaints are logged, and the department of interest inspects them for service and review. In the case of missed trash collection New York City’s Department of Sanitation (DSNY) reviews the complaints. Sanitation has always had a system for reviewing complaints, however, their incorporation into the 311 system has offered them a new opportunity to analyze their information spatially. This is because the data now comes with verifiable geographic location information in the form of X and Y coordinates. DSNY also benefits from 311’s advertising campaign because it has widened the amount of people who are aware that they can call 311 about trash collection. The combination of the geographic location information and the new 311 system has caused DSNY to review how they evaluate their complaint data. It has also created a heightened awareness about using the data to look at the spatial relationship between high complaint areas and socio-demographic This study looks at the spatial patterns of DSNY missed pick-up complaints. It also analyzes whether there is a relationship between spatially clustered complaints and neighborhoods with low density housing, people living in poverty, and minority status.

From Waiting Rooms to Resource Hubs

From Waiting Rooms to Resource Hubs
Author(s): Laura Kurgan, Craig Hosang
Published on: April 6, 2011
In 2010, as a result of the Million Dollar Blocks Project and extensive work on Justice Reinvestment in Central City New Orleans and Brownsville Brooklyn, Laura Kurgan was invited by New York City’s Department of Probation to undertake a project with a department team exploring changes in the infrastructure of probation in the city. The project combined extensive use of DOP data on probationers, in order to understand the spatial dimensions of the city’s probation system, with a design strategy that brought a range of voices, from probationers themselves to their probation officers, into the process. Our report, From Waiting Rooms to Resource Hubs, recommended new design guidelines, services, and networked structures for probation rooms across the city. The outcome was a complete overhaul of their public spaces, transforming inert waiting rooms in court buildings into active information centers, and inserting what we called NeONS — Neighborhood Opportunity Networks — into high-probation zones in all five boroughs. The project, now almost fully implemented, has been recognized by the Bloomberg administration as an exemplary data-driven public policy initiative.
