Survey of street sweeping practices
The MPCA conducted a survey of cities to determine their street sweeping practices, their interest in a street sweeping credit, and their ability to implement different methods for crediting sweeping. We have not yet fully analyzed the data, but some general conclusions include the following.
- 75 cities responded to the survey and indicated they operate a sweeping program. This was a response rate of close to 50 percent. The responses were distributed geographically across the state and covered a wide range of city sizes (large to small).
- About 78 percent indicated they would be likely to participate in a crediting program
- All but 7 cities can track sweeping information, but 66 percent said they cannot relate material collected to a specific geographic area. This is a question we likely will follow-up with, since being able to relate material to a geographic location is potentially a way of targeting sweeping efforts.
- Most cities estimate volume or mass of material collected, but few measure volume or mass or have the ability to measure dry weight of material collected
- Most cities sweep quarterly or less and most do not specifically sweep in response to fall leave drop
