2017 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. 

To accomplish this, 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. 
For in-depth information on the City’s trash load reduction strategy, see the Long-Term Trash Load Reduction Plan and Assessment Strategy (8 Mb).

Based on these designations, route schedules and frequency will be modified by the end of 2017 so that high generation areas and new development will receive adequate service and lower generation areas are not swept as frequently.  These improvements to the sweeping program will help us meet the trash reduction requirements and keep our bay clean.   Please see below for more detail on the designations, what adjustments will take place, and maps so that you can see how your home or business will be affected.

Sweeping Based On Trash Generation

  • 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)

Parking Restriction Signage

Parking restriction signs will be 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.

Route changes and signage will be in place by 2018.  Once these changes are implemented, you will be able to check your current sweeping day on the MyStreet online service. You can also sign up for email notifications to move your car prior to your sweeping time.
