Litter GIS Strategy
Start small Annual data updates Available data in usable form
Build Litter Data Partners SEPTA CDCs University urban researchers Phila GIS Community
Enhance Litter Index Hot Spot Tracking Support Litter Data Analysis
Trend (getting better or worse over time?) Geographic (street segment, PSD collection day, CDC, tract, Council District) Type (property, construction, receptacle) Repeat – chronic areas Relationships with other factors: vacant housing, % renters, crime, income, other)
10/27/2014 30
1. Code Violation Notices Annual updates Street segments with chronic litter code notice issues
2. Trash Receptacles City wire baskets and Big Bellys SEPTA Bus Route receptacles ID chronic receptacle dumping locations
3. Litter Index Survey results very dynamic Release Sub area data - close to segment level Potential Enhancements
Combination of Litter CVN and Litter Index may be helpful Trend by area
4. Develop Data on Street Cleaning Routes with Method, Frequency Information Streets Department CDCs & Neighborhood associations
5. Develop Location Data on Potential Litter Sources Fast Food –convenience stores
6. Establish Illegal Dump tracking log
Start with Focus on Litter Data
