Logan Triangle Illegal Dumping Action Plan
Logan Triangle, like many areas in Philadelphia, suffers from excessive illegal dumping.
At the Logan Civic Association meeting on May 14th, local residents complained about this long term problem and asked for action.
Based on District 8 Trash Task Force meetings, personal investigations and Philadelphia’s Zero Waste and Litter Cabinet information, I have assembled the attached Logan Triangle Illegal Dumping Action Plan to help focus our efforts to tackling the Logan Triangle and wider dumping crisis.
Key points from this draft plan:
- Six Illegal Dumping Control Actions are available to communities and the City
- Encourage community Philly311 reporting
- Engage Area Block Captains (8 in Logan Triangle vicinity)
- Engage SWEEP officers to assess Logan Triangle situation & make recommendations
- Illegal Dumping, Truck Parking Signs
- Enhanced Barriers (specific recommendations for Logan Triangle provided)
- Surveillance Cameras ( 4 proposed for Logan Triangle)
- Logan Triangle has many specific dumping hot spots. 8 action areas have been identified to begin coordinated community – City efforts. Additional action areas will be added as we progress
- Specific action plans have been developed for each of the initial 8 action areas.
- There are 8 Block Captains in the Triangle vicinity. They could provide valuable insight and leadership to our efforts if the Streets Department can facilitate communication between these Block Captains and the District 8 Trash Task Force.
- SWEEP officers have extensive experience assessing trash sources and corrective actions which can help the community efforts. Can the Streets Department facilitate communication between SWEEP officers and the District 8 Trash Task Force?
- Streets placed dozens of concrete barriers around Logan Triangle to limit access to the open land. This report identifies several locations where dumpers are able to bypass the barriers to dump. Specific recommendations are included to move, realign and/or remove barriers by action area.
- Philly311 has accepted multi-block illegal dumping requests and currently is processing requests for 3 of the 8 action areas in Logan Triangle.
- 4 surveillance camera locations are recommended. Can Streets and Philadelphia Redevelopment Authority expedite camera deployment to these 4 Logan triangle locations?

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:
- Little to no litter
- Litter, in the amount that can be picked up by one person
- Litter, in the amount that would need a team to clean up
- 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.
Residential Access to Philadelphia’s Sanitation Convenience Centers
Philadelphia has 6 Sanitation Convenience Centers (SCC) that provide residents safe, free, reliable disposal sites for excess trash and special items like tires and TVs,electronics.
These Centers are a critical resource for the City’s Zero Waste and Litter efforts, however, there are two residential access issues that must be addressed to ensure their potential effectiveness:
- Approximately 33% of Philadelphia Housing Units do not own or lease a vehicle, presenting a serious challenge to residents with excess trash. How do they get their excess trash to an SCC?This map shows the of % households without a vehicle by Census Tract. More than 50% of households do not have a vehicle in 71 census tracts.
Residents how do not have access to a vehicle so that they can not use the City’s Convenience Centers without borrowing or renting a vehicle.
We may need some type of trash taxi service for those households without access to a vehicle. - For those households with a vehicle, travel times from residents’ home to an SCC and back can present a significant time challenge. The following map shows the estimated one-way travel times areas for 5, 10 and 15 minutes trips.
I think that a 15-minute one-way travel time (30 minutes round trip) is the upper limit for residents to transport excess trash to a SCC on a regular basis.
Residents access to an SCC is critical for reducing illegal dumping. The City will need to improve access to the SCCs for households without vehicles and those outside the 15-minute travel time zones

Using Data to Tackle Philadelphia’s Street Trash Problem
Illegal dumping is a growing problem in Philadelphia (link)! We need to understand types – locations – frequency of dumping to stop it. We have the data, we need better data analysis to effectively manage our trash problem.
Here are 3 charts that demonstrate how we can diagnose our trash dumping problem using January, 2017 311 illegal dumping service requests where citizens submitted photos.
Illegal Dumping Trash Types
Illegal Dumping Locations
Illegal Dumping Trash Events
Here’s what we can learn by studying the January, 2017 illegal dumping service requests.
- Residential trash (36%) was the most common type of dumping request, followed by tires and construction debris (12% each), mattresses (10%), mix of trash types (9%) and TVs (7%).
- 66% of illegal dumping requests occurred on sidewalks, followed by 15% on/near vacant lots – buildings.
- 58% of dumping requests occurred at single event sites, 27% at multiple event sites ad 5% at chronic dumping sites.
- Big Belly’s accounted for 5% of Philadelphia illegal dumping service request sites.
- Loose litter accumulation accounted for 5% of Philadelphia’s 311 illegal dumping service requests.

Using 311 Request Data to Understand Philadelphia’s Street Trash Problem
Philadelphia’s 311 OpenData is an excellent research tool to investigate our street trash problem. Philadelphia has used data to fight crime (link) for a long time, it’s now time to use Philadelphia’s 311 data to fight street trash!
We have many of the basic tools necessary for implementing a state-of-the-art street trash management system comparable to our crime data system. We need to increase the City’s focus on street trash and integrate our many resources into a concerted program to address this chronic problem.
In this post I want to show how the City’s 311 data system can be used to better understand our street trash problem and identify potential control strategies based on resident provided street trash data.
Analysis of January, 2017 311 Illegal Dumping Service Requests
There were 1,277 illegal dumping service requests in January, 2017 (link). My earlier posts showed that illegal dumping service requests are increasing and that illegal dumping requests are increasing as a portion of all 311 field service requests (link). What can we learn about the types and locations of trash being dumped?
We can use the photos submitted by 311 users to classify the requests by type of trash, dump site location and dump situation conditions. That’s just what I did.
I downloaded the 1,277 January, 2017 illegal dumping service requests from OpenDataPhilly, selected those requests that had usable photos (302 ) and then classified request by Trash Description, Dump Location Description, and Dump Site Characteristics. Here is a link to my on-line Google Sheet where you can view the classifications and check out the photos.
Click the Link field to view the resident’s submitted image. A new window will pop up showing the actual url with a small arrow . Click the arrow to navigate to the resident’s image.
I used a series of pivot tables to summaries of the Jan, 2017 illegal dumping requests. Here’s what I found out:
- Residential trash (36%) was the most common type of dumping request, followed by tires and construction debris (12% each), mattresses (10%), mix of trash types (9%) and TVs (7%).
- 66% of illegal dumping requests occurred on sidewalks, followed by 15% on/near vacant lots – buildings.
- 58% of dumping requests occurred at single event sites, 27% at multiple event sites ad 5% at chronic dumping sites.
- Big Belly’s accounted for 5% of Philadelphia illegal dumping service request sites.
- Loose litter accumulation accounted for 5% of Philadelphia’s 311 illegal dumping service requests.

Street Trash = Illegal Dumping + Litter
Philadelphia has a street trash problem that is being mislabeled as a litter problem. We all understand litter, the soda bottle, snack food wrapper that is tossed on the sidewalk. Unfortunately we tend to use litter for all “street trash”, both gross illegal dumping and the extraneous snack food wrapper.
I have started using street trash to label all street-sidewalk-vacant lot-park space debris, including tires, TVs, mattresses, bulky items-furniture, residential trash as well as the pedestrian snack food droppings. All is trash, all has wound up in our common space, hence the term street trash.
Here are several Philadelphia 311 illegal dumping service request photos taken from the 311 OpenDataPhilly website (link) on Monday, February 6, 2017.
-
- Big Belly overflowing with trash. Notice plastic bag with happy face next to Big Belly. Excess trash will eventually fall to sidewalk.
-
- Illegal Dumping -bags of trash may rip,spill, and scatter over a wide area, appearing to be “litter” when it is actually trash.
-
- Illegal Dumping – bags will rip and scatter trash, appearing to be “litter”
-
- Street Litter – where did it come from? Was it dropped by pedestrian or dumped in a bag that ripped and spill trash?
-
- Street Litter – looks like residential trash bag opened and spilled
We will only have clean streets when we address and begin to control our illegal dumping crisis. Much of what we call litter actually start as bags of residential trash that are placed on a sidewalk by someone unwilling to wait until the next trash day.
Let’s start to call all dumpers by their right name, DUMPERS. An old mattress or soda bottle tossed on the sidewalk comes from the same thoughtless behavior. We need to go after all dumpers, big and small.
Philadelphia’s Zero Waste & Litter Cabinet (link, link) is a great opportunity for Philadelphia to begin to control out waste & trash future. It is absolutely critical that we recognize the importance of illegal dumping in litter efforts. We need to tackle both illegal dumping and litter to get our streets to the cleanliness level that we want.
ArcGIS Story Map of LA’s Clean Street Index
LA is using ArcMap, dashcam, GPS and cameras to develop detailed street cleanliness index. Click this link to see an interactive Story Map of this innovative use of GIS to tackle a pressing urban problem.
Cleanliness Indexes are available by 39,915 street segment and are summarized into operational grids.
Philadelphia, like LA, has a serious street trash problem. We need to dramatically improve our street cleanliness efforts. Following LA’s Clean Streets Index would be an excellent start for the Mayor’s Zero Waste & Litter Cabinet.

Philadelphia’s Illegal Dumping 311 Requests increased 35% from 2015 to 2016
Many Philadelphians say that our streets are littered, we now have the numbers to back up that opinion. Here’s a comparison of 2015 and 2016 311 Illegal Dumping Service Requests City-wide and by Council District. We had 17,384 in 2016, 35% more than we had in 2015. While Illegal Dumping reports went up in all 10 Council Districts in 2016, Districts 2 and 5 saw 65% and 42% increases, respectively. District 3, on the other hand, only increased 11%.
