Philadelphia Updates, Significantly Improves Street Litter Index

Philadelphia has taken a major step forward with the recent release of the interactive 2017 Litter Index map (link) and supporting data (link).

In my January, 2017 post, I compared Philadelphia’s earlier litter index to the then recently released LA Street Litter Index. LA had made significant improvements in their index. I am thrilled to report that one year later, Philadelphia has a state-of-the-art litter index that  provides litter status data for every street segment in the City.

The new index is based on city block surveys where surveyors assessed the litter  situation on a 4 point scale:

  1. Little to no litter
  2. Litter, in the amount that can be picked up by one person
  3. Litter, in the amount that would need a team to clean up
  4. Litter, requires a large clean effort and/or heavy machinery to remove

Surveyor data included date(s) of survey, litter count for the block as well as a link to field photograph(s).

Users can download the City’s detailed litter survey data at 3 levels of detail:

  • Detailed Survey Points – detailed data for each survey point
  • Street Segments
  • Ward Divisions, aka voting precints

The data is available in CSV files, shapefiles and GeoJSOn files. The best place to start is to look at the Metadata for the point, line and polygon data.

I have started analyzing the 2017 Litter Index Data for Council District 8. These 2 maps show the point survey data and the block – street segment data for Council District 8.

 

 

Congratulations to the City’s Zero Waste and Litter Cabinet for implementing this comprehensive litter measurement system. This data will help community groups, individuals, litter activists and City Departments to focus attention on both city-wide and neighborhood priorities and measure progress as we work together to solve the City’s chronic street trash problem.
