Street Sweeping Program Improvements

By 2022, the City of San Mateo will be required to prevent all trash from entering the bay through our storm drains to meet mandates set by the San Francisco Bay Regional Water Quality Control Board.

You can view your new sweeping day on the MyStreet web tool. To learn more about how trash generation determinations were made, click here to skip to the bottom of this page.

Sweeping Based On Trash Generation

In 2018, the City modified its route schedule and frequency based on the amount of trash generated on a given street. The change meant that service adapted to the needs of the community, and that the sweeping program could meet trash reduction requirements including keep our Bay clean. Please see below for more detail on the designations. Click to enlarge the map below.

  • Green/Low generation streets:  During leaf-season (October to March), these streets will be swept bi-weekly.
  • From April to September, these streets will be swept monthly.
  • Yellow/Moderate generation streets:
    Year-round bi-weekly sweeping
  • Red/High generation streets:
    Year-round bi-weekly sweeping, and addition of parking restriction signs (see below)    TrashGenerationStreets Opens in new window        

Parking Restriction Signage

Parking restriction signs are expanded in red/high generation areas to keep streets clear for their scheduled sweeping. Without cars blocking the gutter of these high-priority streets, the sweepers can thoroughly clean the street and prevent litter from entering the bay. These signs will only restrict parking on the days and times where the gutters need to be clear for sweeping. See the map at right for the proposed new signage.

If you need a prompt to move your car, sign up for email notifications, you’ll get an email prior to your sweeping day.

Trash Generation Assessment Process

To meet the 2022 goals, the City assessed the amount of trash generated on every street throughout San Mateo and put them in three categories. Trash generation ratings of Low, Moderate, and High were determined through a multi-step process:

  1. A draft Trash Generation map was prepared based on land use, population density, and demographic data as part of the Trash Generation Project to address trash reduction and compliance with the National Pollutant Discharge Elimination System (NPDES) permit. For more details on the Trash Generation Project, see the Technical Memo (2012).
  2. Based on this established methodology, City of San Mateo staff gathered trash collection data from the street sweeping program, and conducted site visit observations over a period of time to verify 90% of the City’s moderate and high generation trash areas.
